You might be missing some of the modern WM6 calls. Here's the relevant code from the working ported version of Graphics for the Masses.
I started with working code from the AppWizard. tabs/spaces is pushing the formatting everywhere:
Code:
int WINAPI WinMain(HINSTANCE hInstance,

// Perform application initialization:

I'm using evc4, so I can't build for a THUMB ( wince 5.0 ) device... any way you can recompile the lib for ARMv4?
Otherwise, I'm still linking w/ the Vincent lib.
Anyway, I started a whole new app ( appwizard hello template ) instead of writing the winmain from scratch and I still cannot generate a surface when I have anything but EGL_NONE in the config requests.
One thing I note is that fps is about 47-48, but once again, the texture is not mapped onto the object. If I put it in my folder w/ the Vincent dll, the texture is mapped and the fps is about 11-12.
I'm not quite familiar w/ EGL, but... does anyone know the EGLConfig structure? I tried searching for it to see what the requested width/height per config was so I can debug why the surface just doesn't get created.
anyway, here's my code:

That's ARMv4 or ARMv4i? I'm going to assume latter because that's what most of the dlls seem to be targeting. I'll put this up soon.
Meantime, GetClientRect() on your hwnd and make sure the rect is sane before you pass it on to eglCreateWindowSurface().
Also, Imageon may work better with GLfloat values although it probably kills Vincent (with software emulation on the ARM without native FP support in armv6 by the compiler) with anything but GLfixed. Try some benchmarking to see which works out better.

100000xtimes thanks!

can you make a sourceforce project??

ARMv4 is what evc4 targets...
GetClientRect() is giving me very sane values, 268x240... 268 due to the bars up top & below.
I guess I'm just confused as to why Vincent is able to properly create the proper surface while our drivers cannot...
Edit:
//eglDisplay = eglGetDisplay(EGL_DEFAULT_DISPLAY);
eglDisplay = eglGetDisplay(GetDC(hWnd));
eglInitialize(eglDisplay, &majorVersion, &minorVersion);
eglConfig = select_config(eglDisplay, EGL_WINDOW_BIT, 16, 16, 4);
ctx = eglCreateContext(eglDisplay, eglConfig, NULL, NULL);
eglWindowSurface = eglCreateWindowSurface(eglDisplay, eglConfig, hWnd, NULL);
eglMakeCurrent(eglDisplay, eglWindowSurface, eglWindowSurface, ctx);
/* rest of app init */

I just realized that you don't provide egl config attribs for for eglCreateWindowSurface or for eglCreateContext... huh. Doing that, the surface and context are created ok, but the texture still isn't loaded... mebbe a problem w/ texture loading.

Anywho, it looks like the problem w/ texturing is that our drivers do not seem to support mipmap. By commenting out the linear mipmap flag when loading the texture, we get a fully working opengl es test app. I get about 44 fps.
See for yourselves.
View attachment testapp2.zip
@nushrike, both of your libgles_cm.lib's are designed for the 'THUMB' device. It's ok. I'll just keep on linking to the vincent lib.
Just remember that our driver does not support mipmap.

I think it's eVC is too old then. It's been thumb since WinCE5. Most all the system libs I have to link to insiste on Thumb -- if I set it to ARM, it refuses to link. Hey, that's an idea.. I'll try ARM to see if it generates any .lib.
For hardware, or supported mipmapping (software or not), look up glGenerateMipmapOES(GL_TEXTURE_2D). The tech demo I posted earlier demonstrates this. It's that blurry looking rotating texture behind the checker-board and various other textures.
edit: nope, can't create a dummy .lib by trying to link ARM.
Instead, you can modify Vincent to fake-support the extended functions as you need them and as they exist in the HWA .dll exports list. Here's an example:
Code:
#ifdef __GL_EXPORTS
# define GL_API __declspec(dllexport)
#else
# define GL_API
#endif
#define GL_APICALL GL_API
#define GL_APIENTRY
#ifdef __cplusplus
extern "C" {
#endif
{
GL_APICALL void GL_APIENTRY glGenerateMipmapOES (GLenum target)
{ return; }
#ifdef __cplusplus
}
#endif

No code to make it a SourceForge project. Now, if it was code to make the drivers, that would be worthy.
ycavan: figured out your bug. You have to pass NULL for configAttrib (the last parameter) for eglCreateContext, and eglCreateWindowSurface. Also, using glGenerateMipmapOES(GL_TEXTURE_2D) with your source, texture works fine now. Same FPS. I'm seeing if converting to GLfloat will speed it up.
edit: float is no speed increase so far, but no decrease either.

How do you get this to run? I've already asked you in PM that WinCE doesn't support the concept of "current working directory" and you use in your code.

I'm sorry about not responding to the pm's... lol, I just didn't see them.
Anyway, just unzip the file on your pc and copy the exe and resources folder to your device and run the exe. Just make sure to keep the exe and resources folder together.

It doesn't work for me after I drop it into the "Program Files" folder because this code is hard-coded for root directory then.

really odd... i ran the program in its own directory w/o a problem... i'm @ work, so i'll check it out when i get home.
it looks like the "resources" directory must be on the root of the device...
I'm working on finding the cwd, but loading resources fails even though it's the correct wd...
You guys can try and see if this works...
Code:
TCHAR tPath[255];
char sPath[255];
// get full path to this executable
GetModuleFileName(NULL,tPath,255);
// find the last '\'
TCHAR* pos = wcsrchr(tPath,'\\');
// end the string after the last '\'
*(pos+1) = '\0';
// copy wide char array to multi-byte string
wcstombs(sPath,tPath,255);
sPath should contain the working directory... but my app is failing the resource loads even though this is the same full path as before...

this can be very intresting for xda flame with goforce? can you build the libs because there is no SDK avialeble, the test app doesn't work message:
OpenGL ES init error:
eglInitialize

EDIT:
Just realized that you're talking about another phone w/ the goforce... lol
You will need to prolly google "goforce opengl es sdk" There should be quite a few out there.
On another note... I figured out the problem with working directory resource loading.
I prefer to make a call once when it's something configuration-related... like storing my current working directory... it seems that evc4 doesn't like it when I do that so I had to update mesh.cpp and texture.cpp to perform the GetModuleFileName calls in each load function.
Here's an updated TestApp2. You just need to keep testapp2.exe and the resources directory together.
View attachment testapp2.zip
Updates include:
+ fullscreen now
+ up/down rotation
+ left/right acceleration -100 to 100
+ spouting of particles
Have fun guys.
The resources directory contains these files that you can change if you want to try different things.
spot.raw - the particle system's balls texture
font.raw - the font texture
knot.gsd - the main object mesh
fire128.tga - the mesh object's texture

lol for goforce there are none zero nada

Hi ft1860!
I don't think you can do it that way, although I never tried it. You should check out power management API:
http://msdn.microsoft.com/library/d...pplicationsToTurnSmartphoneBacklightOffOn.asp
This example is for smartphones but should work on a PPC just as well.
P.S.:
Error 161 is "The specified path is invalid" so you should check the device name (no idea what that might be).

hi levenum
Thanks your comment,but according to this document
http://windowssdk.msdn.microsoft.co...r/base/ioctl_video_set_display_brightness.asp
It say we can set the current AC and DC backlight levels by invoke DeviceIoControl with IOCTL_VIDEO_SET_DISPLAY_BRIGHTNESS parameter.
So first I must create a handle of LCD,but I cann't open it successfully,
why?
oh,I make a mistake
IOCTL_VIDEO_SET_DISPLAY_BRIGHTNESS is Win32 function.
On smart device,I should use SetPowerRequirement to set the backlight.
But when I invoke SetPowerRequirement on my Universal with D0 or D4,it say success ,but nothing happened.
maybe you have to access backlight by BKL1: device.
CreateFile(L"BKL1:", ....
or write the brightness value into registry.. that works for sure.

I'll try it.
It seem that SetPowerRequirement D0-D4 just Open or close backlight,
but what I want is adjust the backlight's brightness.

It almost work.
It works fine on my Universal,but it doesn't work on my x50v with WM5.
I should not debug it on my x50v,there is so many bugs in Dell's WM5 update.

WM6 - how to Query WLAN "connection" status

I am desperately trying to work around some unknown problem caused by our NDIS IM driver on WM6 and HTC TyTn ( TyTn at least, but most likely other devices as well ). I started some other threads regarding different facets of this problem, and no help is coming. Now I am just trying to work around it.
in short the problem is when power events happen the WLAN will never connect.
The work around is programmatically open the control panel with STControlPanel class and press the down button 1 time then the f1 key ( right dash ). This "presses connect" on the last configured access point. This works around my problem, however, I need to detect when the access point has connected. There is a "connecting" and "connected" message for the access point in this control panel dialog ( control panel # 17 ).
My Question: Is there some way to get this text "connecting" or "connected" from the control panel #17?
I have tried wzc, ndisuio, winsock, and other "non control panel" ways to detect connected state, but the IM problem fools all these methods. The only thing I have ever seen that successfully shows when the problem has occurred is the "connecting"/"connected" status in the control panel 17.
Please Help Someone.
p.s. If I can get this worked around, we sell a commercial grade ndis intermediate driver toolkit letting you easily write plugins without any of the hard driver details. We have redirectors, transparent proxy, tunnelers, virtual adapters, lots of good stuff. Also the same plugin will work on all windows desktop platforms vista - 98, WM5/6 and CE and also linux and solaris...

Need C# xml ready/write example - Stummped!

OK I am writing my first Mobile 6 App, based on compact framework 2, obviously finding some differences from Framwork vs compact when dealing with reading and writting simple values to xml;
Here is what I want to do: write two textbox values to xml as follows:
<settings>
<hostip>192.168.0.14</hostip>
<hostport>8011</hostport>
</settings>
So I got the above accomplished using the following code:
--------------------
string hstip = "";
string hstport = "";
hstip = this.HostIP.Text.ToString();
hstport = this.HostPort.Text.ToString();
XmlWriterSettings xml_settings = new XmlWriterSettings();
xml_settings.Indent = true;
xml_settings.OmitXmlDeclaration = false;
xml_settings.Encoding = Encoding.UTF8;
xml_settings.ConformanceLevel = ConformanceLevel.Auto;
using (XmlWriter xml = XmlTextWriter.Create(GetApplicationDirectory() + @"\settings.xml", xml_settings))
{
xml.WriteStartElement("settings");
//xml.WriteStartAttribute("hostip", "");
xml.WriteElementString("hostip", hstip);
//xml.WriteString(hstip);
//xml.WriteEndAttribute();
xml.WriteElementString("hostport", hstport);
//xml.WriteStartAttribute("hostport", "");
//xml.WriteString(hstport);
//xml.WriteEndAttribute();
xml.WriteEndElement();
//ds.WriteXml(xml);
xml.Close();
}
-----------end of write code------------
Now the part I am stumped on as I have tried all varietions to get the data back into the textboxes, I either get and exception or blank values in the textboxes.
Here is the code:
------------------
private void SrvSettings_Load(object sender, EventArgs e)
{
XmlReaderSettings xml_settings = new XmlReaderSettings();
xml_settings.IgnoreComments = true;
xml_settings.IgnoreProcessingInstructions = true;
xml_settings.IgnoreWhitespace = true;
xml_settings.CloseInput = true;
try
{
using (XmlReader xml = XmlTextReader.Create(GetApplicationDirectory() + @"\settings.xml", xml_settings))
{
xml.ReadStartElement("settings");
xml.Read();
xml.ReadElementString(,,)
//xml.ReadToFollowing("hostip");
this.HostIP.Text = xml.GetAttribute("hostip","");
//this.HostIP.Text = xml.GetAttribute("hostip");
//xml.ReadToFollowing("hostport");
this.HostPort.Text = xml.GetAttribute("hostport","");
// Close it out----------------
xml.ReadEndElement();
xml.Close();
//ds.ReadXml(xml);
// }
}
}
catch (Exception ex)
{
System.Windows.Forms.MessageBox.Show(
ex.ToString(), "Error Loading IP settings");
}
}
------------end of read code
obviously I get an exception with this:
"System.xml.xmlexception:
"Text" is an invalid XmlNoteType. Line 2, posistion 11 at
System.xml.xmlReader.ReadEndElement()"
-----
I suspect I need to use ReadElementString, but I have tried and no workie...
Somebody have an example/class for both reading and writing per my requirements above, I would really appreciate the help..
Use XmlDocument
Try using the XmlDocument instead. It's alot easier to use for simple xml reading/writing.
Well Partially working now - I get the Hostport populated but for some reason hostip is blank even though it appears it falls through it in the case statement.. wierd..
DataSet ds = new DataSet();
XmlReaderSettings xml_settings = new XmlReaderSettings();
xml_settings.IgnoreComments = true;
xml_settings.IgnoreProcessingInstructions = true;
xml_settings.IgnoreWhitespace = true;
xml_settings.CloseInput = true;
try
{
using (XmlReader xml = XmlTextReader.Create(GetApplicationDirectory() + @"\settings.xml", xml_settings))
{
xml.MoveToContent();
xml.ReadStartElement("settings");
while (xml.Read())
{
//xml.Read();
switch (xml.Name)
{
case "hostip":
HostIP.Text = xml.ReadString(); <--I get Blank text
break;
case "hostport":
HostPort.Text = xml.ReadString(); <--POpulated OK
break;
default:
break;
}
// Close it out----------------
//xml.ReadEndElement();
}
xml.Close();
//ds.ReadXml(xml);
// }
}
}
Solved, Had to remove the line: xml.ReadStartElement("settings");
Thanks..
Just out of curiosity, what will your app do ?
I'm writing a WPF Windows App that monitors Server Services, IPs, Websites for up or down status; buiding a client server component to it, so the end goal will be to use the mobile app to connect to the host and download status on said servers being monitored and populate them in a listview whith thier up or done status.
Simple app but still in the works.
if you can make it customizable (to set up parametres, adreses) it wil be useful for many website administrators
a cool little app

Direct X and PNG Transparency on WM6.1 with .Net CF3.5

Hi all,
I'm trying to have transparent PNGs on my screen.
What is the best way to doing this ? I'm in C#, I tried DirectX, but it doesn't work.
What am I doing wrong ?
My code :
Code:
using System;
using System.Drawing;
using System.Windows.Forms;
using Microsoft.WindowsMobile.DirectX;
using Microsoft.WindowsMobile.DirectX.Direct3D;
using System.Runtime.InteropServices;
namespace Microsoft.Samples.MD3DM

Texture texture = null;
Sprite sprite = null;
Rectangle rect;
public SimpleSMS()
{
// Set the caption
this.Text = "SimpleSMS";
this.MinimizeBox = false;
}
// Prepare the rendering device
public bool InitializeGraphics()
{
try
{
// Now let's setup our D3D parameters
PresentParameters presentParams = new PresentParameters();
presentParams.Windowed = true;
presentParams.SwapEffect = SwapEffect.Discard;
device = new Device(0, DeviceType.Default, this, CreateFlags.None, presentParams);
this.OnCreateDevice(device, null);
}
catch (DirectXException)
{
return false;
}
return true;
}
void OnCreateDevice(object sender, EventArgs e)
{
texture = TextureLoader.FromFile(device, @"badge.png");
sprite = new Sprite(device);
rect = new Rectangle(0, 0, 48, 48);
}
// All rendering for each frame occurs here
private void Render()
{
if (device != null)
{
device.Clear(ClearFlags.Target, System.Drawing.Color.Black, 1.0f, 0);
//Begin the scene
device.BeginScene();
device.RenderState.SourceBlend = Blend.SourceAlpha;
device.RenderState.DestinationBlend = Blend.InvSourceAlpha;
device.RenderState.AlphaBlendEnable = true;
sprite.Begin(SpriteFlags.AlphaBlend);
sprite.Draw(texture, rect, new Vector3(0.0f, 0.0f, 0.0f), new Vector3(100.0f, 100.0f, 0.0f), Color.White.ToArgb());
sprite.End();
//End the scene
device.EndScene();
device.Present();
}
}
// Called to repaint the window
protected override void OnPaint(System.Windows.Forms.PaintEventArgs e)
{
// Render on painting
this.Render();
// Render again
this.Invalidate();
}
// Called to repaint the window background

// Initialize Direct3D
if (!frm.InitializeGraphics())
{
MessageBox.Show("Could not initialize Direct3D. " +
"This tutorial will exit.");
return;
}
Application.Run(frm);
}
}
}
Thanks for answers,
Scuse my bad english :-/
Not sure this helps, but RLTODAY works very well with transparent pngs in any WM version, and recently he released the source code:
http://rotlaus-software.de/forum/index.php?topic=1847.0
You can use ImagingFactory in OpenNETCF or other wrapper over the internet. PNGs with alpha work work for me.
AlphaControls
There is a project on Codeplex that can help you with transparency called AlphaControls. Also have a look on codeproject at the iPhone app clone

Thank you all for answers ...
I tried OpenNetCF, without any result.
Do you have a piece of code in example ?
Try this:

[WM6] Disabling taskbar, SIP and hardware keys (including green and red buttons)

Hello there!
I've seen a lot of questions on this topic, and just yesterday, my client asked for this feature implemented in the app that we are currently developing...
After a veeeery intensive and long night, i finally found how to disable all these things! The code is written in c# using .net CF 2.0, and has been tested successfully on a HTC Tynt device. The interesting thing is that it will also disable the End Call and Make Call hardware buttons (VK_TEND and VK_TTALK). If you intend to use this in a production environment you might consider improoving it a little bit.
[DllImport("coredll.dll")]
private static extern bool UnregisterFunc1(KeyModifiers modifiers, int keyID);
[DllImport("coredll.dll", SetLastError = true)]
public static extern bool RegisterHotKey(IntPtr hWnd, // handle to window
int id, // hot key identifier
KeyModifiers Modifiers, // key-modifier options
int key //virtual-key code
);
public enum KeyModifiers
{
None = 0,
Alt = 1,
Control = 2,
Shift = 4,
Windows = 8,
Modkeyup = 0x1000,
}
private void DeactivateUI()

try
{
// deactivate the SIP button
IntPtr hSip = FindWindow("MS_SIPBUTTON", "MS_SIPBUTTON");
EnableWindow(hSip, false);
// deactivate the SIP button
IntPtr hTaskBar = FindWindow("HHTaskBar", null);
EnableWindow(hTaskBar, false);
// deactivate the hardware keys
for (Int32 iCounter = 193; iCounter <= 207; iCounter++)
{
UnregisterFunc1(KeyModifiers.Windows, iCounter);
RegisterHotKey(this.Handle, iCounter, KeyModifiers.Windows, iCounter);
}
UnregisterFunc1(KeyModifiers.None, 0x73); //VK_TEND
RegisterHotKey(this.Handle, 0x73, KeyModifiers.None, 0x73);
UnregisterFunc1(KeyModifiers.None, 0x72);
RegisterHotKey(this.Handle, 0x72, KeyModifiers.None, 0x72); //VK_TTALK
}
catch (Exception ex)
{
Log.WriteError(ex, false);
}
}
Cheers!
Very good, helped me a lot! But how do I unlock the keys again, without rebooting?
Thanks!

Can u provide the EnableWindow method.I am getting the error in this method
Implement code
Hello!
I have created app to WM 5 - 6.5, but users can close it using END button. I see your code, but i can't implement ( i mean I don't have sufficient knowledge) it to visual studio 2008.
Could you tell me what should I do?
