The best approach is always to use the debugger. Run your program under the debugger (Build, Start Debug, Go). Do whatever you did to make the error occur. You'll get a dialog box reporting a 'First chance exception in MSVCRT.DLL (code 0xc0000005)'. Note the position of the instruction pointer. Look at the call stack window to see which part of your program called into the C runtime.

You probably passed a NULL or invalid pointer into the C runtime somewhere. Most commonly this is due to an uninitialised variable: the debug version of the C runtime will initialise the stack to 0xCCCCCCCC, while the release version does not do this. The reason for doing this in debug mode is specifically to catch uses of bad pointers.

just create and object of that dialog and call DoModal function.

eg:

CMydialog MyDlg;
MyDlg.DoModal();

But i can't.
because i create the dialog by pointer
CMydialog* MyDlg;
And i use
this->MyDlg->ShowWindow(SW_SHOW);
to show the window...

But it is not modal window...
I want to set it to be model window...
how can i do it?
Thx Smile | :)

Anybody who is very familiar with WIN CE 4.2 emulator? I 'm using VC++ 6.0, together with embedded VC++ 4 to develope 2 programs, one on the desk top, using VC++6.0, and the other on emulator platform, on the same desktop. These 2 programs are to communicate with each other using sockets. However, there seems to be limitation on the emulator as it prevents such communications.

Ensure that you have a virtual network adapter enabled. In eVC, go to Tools, Configure Platform Manager, select the emulator from the tree, click Properties, then click Configure next to 'Emulator Startup Server'. From here, select either 'NAT (Outgoing only)' if the emulated CE device has to connect to the PC, or 'VirtualSwitch'. Selecting 'VirtualSwitch' makes the device effectively appear as an additional network card on your machine.

You then may need to configure the network card inside the emulator.

You might need the Virtual Machine Network Driver[^] to make VirtualSwitch work.

Thank you for the help given!

However, I'd followed your instructions given and my PC program (developed using CSocket, under VC++) still cannot establish connection with my WIN CE program (developed using CSocket, under eVC++) , running within the emulator. Approach taken in the program development is very similar with programs reside on 2 different desktop PC. I've set the port number to be 4000 and host name as the emulator.

overide the PreTranslateMessage message function and put the following code there

eg :

BOOL CMyDlg::PreTranslateMessage(MSG* pMsg) <br />
{<br />
    if( WM_KEYDOWN == pMsg->message )<br />
    {<br />
        if( VK_RETURN == pMsg->wParam )<br />
        {<br />
            pMsg->wParam = VK_TAB;<br />
        }<br />
    }<br />
    return CDialog::PreTranslateMessage(pMsg);<br />

when the cursor came into m_edit, u will get the WM_SETFOCUS message. u can do the getwindowtext and setwindowtext from there..

eg:

BOOL CMyDlg::PreTranslateMessage(MSG* pMsg)
{
if( WM_KEYDOWN == pMsg->message )
{
if( VK_RETURN == pMsg->wParam )
{
pMsg->wParam = VK_TAB;
}
}
else if( WM_SETFOCUS == pMsg->message )
{
HWND hWindowHandle = (HWND)pMsg->wParam;
if( hWindowHandle == m_rich.m_hWnd )
{
// do GetWindowText or SetWindowText or what ever u want
}

}
return CDialog::PreTranslateMessage(pMsg);

}
