How to create a GPRS connection in eVC?

As IE, MSN, when it launches, it creates a GPRS connection to Internet automaticly.
How can I do such thing in my own program in eVC 4.0 ?
Thanks.

All right.
No one answers my question, so I do it by myself. :evil:

Create file error when open LCD

I'm try write a application to addjust LCD backlight.But it failed at the
first step Create file.GetLastError return 161.
Somesone can tell me what's wrong with it?
Sorry for my poor english.
thx
Below is my code

{
MessageBox(NULL,_T("Got Lcd"),_T("MyMessage"),MB_OK);
}
CloseHandle(hLCD);
return 0;
}

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.

then just do it through registry.

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.
Another question is how to get the max brightness value.On my Universal it is 10,but on my x50v it is 8;

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...

Starting chronometer with if condition comparing strings

I have an android application that is receiving a string from an arduino via Bluetooth, names the string "data" and displays it by setting a TextView to the string "data". I want a chronometer to start when the incoming string matches a predefined string.
For example:
Code:
if data.equals(startChrono)){
chronometerLeft.setBase(SystemClock.elapsedRealtime());
chronometerLeft.start();
I actually have the arduino sending a "g" and am setting my string goL to be "g" but cannot get the chronometer to start when the g is received. My TextView shows the g. Code is below. I've tried several things and at a loss. Using same code for chronometer.start() with onClickListener with a button works great. I just need it to start the chronometer when i receive a specific string from the arduino.
Code:
beginListenForData();
// text.setText("Bluetooth Opened");
}
void beginListenForData() {
final Handler handler = new Handler();
final byte delimiter = 10; // This is the ASCII code for a newline
// character
stopWorker = false;
readBufferPosition = 0;
readBuffer = new byte[1024];
workerThread = new Thread(new Runnable() {
public void run() {
while (!Thread.currentThread().isInterrupted() && !stopWorker) {
try {
int bytesAvailable = mmInputStream.available();
if (bytesAvailable > 0) {
byte[] packetBytes = new byte[bytesAvailable];
mmInputStream.read(packetBytes);
for (int i = 0; i < bytesAvailable; i++) {
byte b = packetBytes[i];
if (b == delimiter) {
byte[] encodedBytes = new byte[readBufferPosition];
System.arraycopy(readBuffer, 0,
encodedBytes, 0,
encodedBytes.length);
final String data = new String(
encodedBytes, "US-ASCII");
readBufferPosition = 0;
handler.post(new Runnable() {
public void run() {
text.setText(data);
String goL = "g";
String goR = "f";
chronometerLeft = (Chronometer)findViewById(R.id.chronometerLeft);
chronometerRight = (Chronometer)findViewById(R.id.chronometerRight);
if(data.equals(goL)){
chronometerLeft.setBase(SystemClock.elapsedRealtime());
chronometerLeft.start();
if(data.equals(goR))
chronometerRight.setBase(SystemClock.elapsedRealtime());
chronometerRight.start();
}
}
});
} else {
readBuffer[readBufferPosition++] = b;
}
}
}
} catch (IOException ex) {
stopWorker = true;
}
}
}
});
workerThread.start();
}

Sorry to bother, but in your while loop condition, what does the '!' before Thread do?
