Hi there.
I'm learning how to write programs for my mobile, and at the moment, I'm working on an app which will generate a playlist for TCPMP and then launch TCPMP.
I've got right to the last bit, but now I can't find out how to execute the app.
I'm assuming that you do something like
system.shell("\path\to\app.exe")
But I can't find the system.shell (or equiv.) to run.
Can anyone point me in the right direction?
Thanks

JonTheNiceGuy: with such a question, you really need to specify language, development environment (ideally) and target OSi.
I'm a c++ man, for which I'd createprocess or shellexecute.

Oops! Stupid of me. VB.net
In the Compact Framework system.diagnostics.process allows you to start an application and provide arguments for it
I've just tried to add the following code (each without success)
Dim process as system.diagnostics.process
Dim process as New System.Diagnostics.Process
Is this right? All I seem to have under system.diagnostics is stuff to do with tracing and debugging, not to start new processes, and I there doesn't seem to be any references I can add for it either...
Rgds,
Jon
I do not believe you can use System.Diagnostics.Process to run processes if you are using Compact Net Framework 1.x, (you can in the full net framework). Not sure about 2.x as I have not migrated yet.
try (this is C#)
[DllImport("coredll.Dll",EntryPoint="CreateProcess")]
private static extern int CreateProcess(string strImageName, string strCmdLine, IntPtr pProcessAttributes, IntPtr pThreadAttributes , int bInheritsHandle, int wCreationFlags, IntPtr pEnvironment, IntPtr pCurrentDir, Byte[] bArray, ProcessInfo oProc);
......
......
then
ProcessInfo pi = new ProcessInfo();
CreateProcess("myprogname", "-myprogargs", IntPtr.Zero, IntPtr.Zero, 0, 0, IntPtr.Zero, IntPtr.Zero, new Byte[128], pi)
So... here's my code so far (stripped out non-essential bits). Clicking on a button on the form triggers the sub doLaunchPlayer().
Code:
Imports System.Runtime.InteropServices
Public Class Starter
Dim strOutFile As String = "\stream.m3u"
Private Sub doLaunchPlayer()
SpawnProcess(strOutFile, "")
End Sub
Private Declare Function CreateProcess Lib "coredll.Dll" (ByVal strImageName As String, ByVal strCmdLine As String, ByVal pProcessAttributes As IntPtr, ByVal pThreadAttributes As IntPtr, ByVal bInheritsHandle As Integer, ByVal dwCreationFlags As Integer, ByVal pEnvironment As IntPtr, ByVal pCurrentDir As IntPtr, ByVal bArray() As [Byte], ByVal oProc As ProcessInfo) As Integer
Private Sub SpawnProcess(ByVal Application As String, ByVal Arguments As String)
Dim pi As New ProcessInfo
CreateProcess(Application, Arguments, IntPtr.Zero, IntPtr.Zero, 0, 0, IntPtr.Zero, IntPtr.Zero, New [Byte](128) {}, pi)
End Sub
End Class
Public Class ProcessInfo
Public Process As Integer
Public Thread As Integer
Public ProcessID As Integer
Public ThreadID As Integer
End Class
It's not running the associated application for a .m3u file. Changing to the following doesn't work either:
Code:
Private Sub doLaunchPlayer()
SpawnProcess("\Program Files\TCPMP\Player.exe", strOutFile)
End Sub
Any thoughts?
1) You should check the return code of CreateProcess.
2) Does VB need CreateProcess("\\Program Files\\TCMP\\...... ?
3) Try with a fullpath to Word or another integrated app, to check your code is correct.
I'd got the code wrong. Thanks for the pointer - I was looking in the wrong place for the exe!

Hi there,
OK, I took the hint about using shellexececuteex, but I can't find a code snippet which does the trick!
I found this link which gives some good code, but when I put it in my VB.NET app, it doesn't seem to like it.
At the line
Code:
DllImport("coredll") _
Private Shared Function ShellExecuteEx(ByVal ex As SHELLEXECUTEEX) As Integer
it says "Statement is not valid in namespace."
and
Code:
<DllImport("coredll")> _
Private Shared Function LocalAlloc(flags As Integer, size As Integer) As IntPtr()
says "Statement cannot appear within a method body. End of method assumed.
Can anyone point me in the right direction? Once I know what I'm doing (which may be a while!), I've got some funky stuff I want to do, but I need to figure out what I'm doing wrong first...
Thanks

I need to execute a m3u file, or (in another case) a cab file.
I can't help you with the .NET stuff, but if you are trying to install cabs programatically you should read up on wceload.exe and it's parameters.
Unfortunately this will still require the use of CreateProcess (something that is very easy in native code, but apparently not so in .NET) but you will have control over several things like messages asking were to install and progress bar being shown.
http://msdn.microsoft.com/library/d...n-us/wcepbguide5/html/wce50lrfWceloadTool.asp
Bump
Just to let you all know, I got around needing the .cab file thang by installing the MrClean AUK2 ROM. I still want to be able to launch files with any extension though.
Jon
Use the registry to find out what program should launch for that extension and then launch that program with the file name as a parameter.
Which is what I was after in this thread where people told me to use ShellExecuteEX! LOL
If you can tell me how to get the application handler from the registry based on a file extension, then I'll write it into my app, otherwise, I'll need to use the ShellExecuteEX to launch the file, and let Windows handle the extension.
Hi,
i try to access ril functions from VB.NET
but get an NotSupportetException if i call RIL_Initialize.
Need help please:
Code:
Private Shared hRil As Long = 0

If (hRil = 0) Then
Try
Dim cbResult As dRilResultCallback = AddressOf RilResultCallback
Dim cbNotify As dRilNotifyCallback = AddressOf RilNotifyCallback
nRetVal = RIL_Initialize(1, cbResult, cbNotify, 0, 0, hRil)
Catch ex As Exception
MsgBox("Execption: " & ex.Message, MsgBoxStyle.Critical)
End Try
End If
i have found 1000 samples in C++ but i to really hard to translate it in VB.
I am not familiar with VB.NET, but few suggestions:
1. If you debug the program with emulator, make sure you choose the EMU image with virtual RIL support.
2. If you debug the prog with WM5 device, make sure you have priviledge signed your prog.
3. In C++, I use &g_hRil instead of g_hRil in the last para of Ril_Initial function, any idea?
4. Pay more attention to the CALLBACK functions, Result callback and Notify callback.
ahe said:
2. If you debug the prog with WM5 device, make sure you have priviledge signed your prog.

I test this way. Perhaps if i use certificates it works.
Then simply signed it with WM5 SDK test priviledged cert.
Ok, my certification is installed and isgned the app.
But same error.
It looks like an error in declaraion....

The RIL declarations are not correct
Code:
[FONT=Verdana, Arial, Helvetica][SIZE=2][COLOR=#333333]typedef void (CALLBACK *RILRESULTCALLBACK)(
DWORD dwCode, // @parm result code
HRESULT hrCmdID, // @parm ID returned by the command that originated this response
const void* lpData, // @parm data associated with the notification
DWORD cbData, // @parm size of the strcuture pointed to lpData
DWORD dwParam // @parm parameter passed to <f RIL_Initialize>
);
typedef void (CALLBACK *RILNOTIFYCALLBACK)(
DWORD dwCode, // @parm notification code
const void* lpData, // @parm data associated with the notification
DWORD cbData, // @parm size of the strcuture pointed to lpData
DWORD dwParam // @parm parameter passed to <f RIL_Initialize>
);
[/COLOR][/SIZE][/FONT]
[FONT=Verdana, Arial, Helvetica]
[/FONT] lpData is long in the C declaration, then try to cast it later, not in the declaration directly.
[FONT=Verdana, Arial, Helvetica]Change your Byte() in the callback to IntPtr. And use Marshal.PtrToStruct to put it in one of the RIL structs to get the data.[/FONT]
Then in order to simplify your job, why don't you write a library in C/C++ that you call in your VB.net appl. in place of trying to port the code directly and reinvent the wheel.
ps.: as I said .NET is crap, just use a real programming language.

Using vb.net i have created an application which listens on TCP port 85 for incoming connections via telnet, reads a line of text (until ascii 13) and then parses that line (phone number, ascii 9, sms message, ascii 13) and sends it as an sms....
I have two small problems:
1: i am unable to work out if the sms was sent ok or not, i do not know how to get the return code from the send sms function into a useable format...
2: all this works fine (apart from the above) it parses the line, and sends the sms (i know it sends as it delivers to my other phone, but i need to have it print the result to the socket) but ONLY over the USB connection on 169.254.x.x, and not if i change the listening IP to 192.168.0.12 (this is a static ip the device is always assigned by my dhcp server) i cannot connect to the server. I would like to use this wirelessly as that way i can forward the port using my router and therefore access the sms on the phone from an external server without needing my laptop to be switched on!
I have included my code below... excuse the sloppiness, i only started using vb.net today, but any help in trying to acheive what i am attempting would be much appreciated!

Read the MSDN library about minimising/closing .net cf forms. The MSDN library shows you a little image of a device for methods/properties etc that are supported, minimize is not.
Be aware though that form's by default are minimised and not closed when pressing the X in the corner. I've never tried this nor recommend it but see what happens when you call form.close() method in the load, it may minimse the form or it may crap out all together. What are your reasons for doing this?
Take it from someone who develops on these devices for a living.., programming the .net compact framework can be a very frustrating effort at times. You work with a much lower subset of functionality than in the full framework, you have to take caution to how much memory you use, some things don't work the same way as they do on the full framework and the most recent discovery I've had is that the same framework on different os's can have very different behaviour, i.e. control events firing when hiding them.
Good luck
Here are a few useful tricks using p/invoke that some developers may find usefull and some were hard to find on the net so I created my own Wrappers with a little research.
The following code is a Helper Class to apply the WM6.5 visual styles to some controls using .net framework. This Wrapper lets you apply the visual style to the Tab Control, Apply Background Image to ListView, Enable Double Buffering for ListView, Show Grid Lines in ListView and Enable Visual Style for ListView. To call these functions you just simply put the control in the brackets you wish to apply the visual style to. For Example: EnableListViewStyle(lvMyListview)

Hi, I have also wrote my own Window API wrapper which allows for enabling and disabling windows, getting the full exe file path from a given window class, a simple class for restarting an application and more will be uploaded soon. All this is used in my Touch Tools 2.0 Suite!
Great to know!, looking forward for your release
Can you add
wifi on/off/toggle
bluetooth on/off/toggle
gprs on/off/toggle
VisualStyleHelper needs WindowHelper class, which is not included. Google search for WindowHelper shows C# class only, no VB code.
Here it is:
Code:
Public Class WindowHelper
Private Const GW_HWNDFIRST As UInteger = 0
Private Const GW_HWNDLAST As UInteger = 1
Private Const GW_HWNDNEXT As UInteger = 2
Private Const GW_HWNDPREV As UInteger = 3
Private Const GW_OWNER As UInteger = 4
Private Const GW_CHILD As UInteger = 5
<DllImport("coredll.dll")> _
Public Shared Function GetWindow(ByVal hWnd As IntPtr, ByVal uCmd As UInteger) As IntPtr
End Function
<DllImport("coredll.dll", SetLastError:=True)> _
Public Shared Function GetWindowText(ByVal hWnd As IntPtr, <Out()> ByVal lpString As StringBuilder, ByVal nMaxCount As Integer) As Integer
End Function
<DllImport("coredll.dll", SetLastError:=True, CharSet:=CharSet.Auto)> _
Public Shared Function GetWindowTextLength(ByVal hWnd As IntPtr) As Integer
End Function
<DllImport("coredll.dll")> _
Public Shared Function GetParent(ByVal hWnd As IntPtr) As IntPtr
End Function
<DllImport("coredll.dll")> _
Public Shared Function GetWindowLong(ByVal hWnd As IntPtr, ByVal cmd As Integer) As Integer
End Function
<DllImport("coredll.dll")> _
Public Shared Function GetActiveWindow() As IntPtr
End Function
<DllImport("coredll.dll")> _
Public Shared Function SetWindowLong(ByVal hWnd As IntPtr, ByVal nIndex As Integer, ByVal newWndProc As IntPtr) As Integer
End Function
End Class

Lol, how could I have missed including the Window Helper Class! I will prepare some files and include all my classes in them so it will give everyone better understanding.

Good. I tried to convert VC# Window helper, everything works except EnumChildWindows (VB reports missing type Window). Any ideas on it?
Awesome work, will try it when i finish the main skeleton of my little program. Will post soon.
... and thank you
