Of course I am NOT using an uninitialized Pointer!!! There is some code before, which allocates memory and puts data to this buffer. I am just new to this GDI stuff and I believe there must be something wrong in these lines....

Simpilest way:
1) Create a display compatible dc.
2) Create a display compatible bitmap.
3) Select the bitmap into the dc.
4) Draw on the bitmap via the dc.
5) Select the old bitmap into the dc.
6) Release the dc you created.
7) You now have a bitmap with text on it.
Your code is a bit to complicated and you are drawing on 2 different DCs, drawing text is the same as drawing a line or a rectangle. All your drawing must be done on the SAME DC, after all that is where your drawing area is (the bitmap).

If WM_PAINT shows up with an hDC of 0 -- does that mean anything?

It means it's working as expected. As far as I know, WM_PAINT doesn't send an hDC; both wParam an lParam in that message are unused.
Maybe you mean some other message?

Thanks for the help -- I don't know all the details anymore. My boss came in wondering why this was happening...
I didn't have an answer for him...

Hi,
I have written a program. It is doing what I expected but I am not able to detect a window within that program.
Is there any function in win32 or.... which can be used to detect that window?
Please help
Thanks

Thanks for replying...
Here's my code.
// TSCalibrate.cpp : Defines the entry point for the application.
#include "stdafx.h"
#include "CWin32AbsPointAPI.h"
void main ()
{
}
int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
CTouchScreenAPI* pTouch;
HWND hCalWin;
DWORD SYNCRONIZE;
DWORD procId;
HANDLE hProcess;
DWORD dwWaitResult;
pTouch = CTouchScreenAPI::Create();
if (pTouch)
{
if (pTouch->Init())
pTouch->Recalibrate();
else
MessageBox(NULL, "Created touchscreen interface OK, but Init() failed", "Info", MB_OK);
HWND hCalWin = ::FindWindow(pszABSPOINT_WND_CLASS_NAME, NULL);
GetWindowThreadProcessId(hCalWin, &procId); // retrieves the identifier of the thread that created this window.
hProcess = OpenProcess(SYNCHRONIZE, FALSE, procId); //returns a handle to an existing process object
/* SetForegroundWindow(hCalWin);
DWORD AllowSetForegroundWindow(procId);
if (AnyPopup())
{
DisplayWindow(hCalWin);
}
//AnyPopup();
while( true )
{
if( ! IsWindow(hCalWin) )
break; // window is gone;
// Sleep( 1000); // wait a second for window to close
};*/
while (1)
{
dwWaitResult = MsgWaitForMultipleObjects(1, &hProcess, FALSE, 30*1000, QS_ALLINPUT);
if (dwWaitResult == WAIT_OBJECT_0 + 1)
{
MSG xMsg;
while (PeekMessage(&xMsg, NULL, 0, 0, PM_REMOVE))
{
if (xMsg.message == WM_QUIT)
return 1;
TranslateMessage(&xMsg);
DispatchMessage(&xMsg);
}// end of PeekMessage while loop.
}
else if (dwWaitResult == WAIT_TIMEOUT)
{
SendMessage(hCalWin, WM_CLOSE, 0, 0);
//TerminateProcess(hProcess, 0);
break;
}
else dwWaitResult == WAIT_OBJECT_0;
{
//Calibration process completed;
break;
}
}
}
else
{
MessageBox(NULL, "Unable to get pointer to Touchscreen interface", "Info", MB_OK);
}
return 0;
}
This program is running calibration of a machine.
When I run this on command window, it does the calibration and the cursor in command window moves to the next line showing that calibration is done without detection.
I want to detect that window.
Please help

Why do you have both main() and WinMain()?
I'm still not clear as to what window you are wanting to "detect" but the first thing that jumps out at me is that the calls to FindWindow(), GetWindowThreadProcessId(), and OpenProcess() could fail. Why are their return values not being checked? Could that be a reason why the window is not being detected?

This Program is to detect the window. I associate this program with my calibration process in a machine.Calibration Process is working but it isn't able to detect this window. That's what I am looking for.
I know I need to add few lines in this code. But don't know what to add.
I really don't have any idea how to do this.
Help
Thanks

What window? The window that belongs to your program, or a window that belongs to some other process? What does the "calibration process in a machine" have to do with any of this? Is that related to this mysterious window somehow?

I am using a child frame window to display a view. The child frame window can be resized and when the frame is made smaller than the view scroll bars are appearing and ruining the effect that I want to achieve. The view was created in the resource editor and is of type CFormView. The frame is of type CMDIChildWnd. I have tried a bunch of the following combinations and this is where I am at...
ModifyStyle(WS_MAXIMIZEBOX | WS_MINIMIZEBOX | WS_SYSMENU | WS_THICKFRAME | WS_CAPTION | WS_BORDER | WS_HSCROLL, 0, SWP_NOMOVE);
ModifyStyleEx(WS_EX_STATICEDGE | WS_EX_RIGHTSCROLLBAR, 0, SWP_NOMOVE);
Doesn't work
Any insight???

What is that effect? You might handle WM_SIZE messages in your view and call SetScrollSizes from the corresponding OnSize function. But what to do exactly might depend on what you are trying to achieve.

Thank you for your response. I am actually asking this question for a co-worker so I needed to find out what effect he wanted. Basically, it is whenever the child window is resized to a smaller size he does not want the vertical or horizontal scrollbars to appear. I hope that makes some sense.

Not much more than the original question, but never mind. If your co-worker is interested, tell him/her to post him/herself to the forum, an explain a bit more.

I have an mfc ActiveX control. It exports a few functions and uses an COleControl for its main window. Basically on this machine I have running win2K it crashes when closing down.
The crash occurs in AfxWinProc due to the module state returning a null CWnd pointer given the hwnd - the message is WM_DESTROY. Somehow MFC has gone and dumped all its hWnd to CWnd* maps and the call to AfxWinProc causes the whole thing to just crash.
Unbelievably MFC doesnt simply test for a null CWnd pointer, it insists on just ASSERTing it like mad and trying to carry on regardless.

I have a dialog based application very simple (visual c++ .net). i added a windows media player control to the dialog resource. next i gave an id IDC_PLAYER. next i added a variable called m_ctrlPlayer(Add Variable). I have also a button (play) and below is the event handler for that button.
void CWindowMediaDlg::OnBnClickedPlay()
{
// TODO: Add your control notification handler code here
m_ctrlPlayer.GetControls().play();
}
i get this error when i try to compile the project....

 Quite strange. How have you added Windwos Media to your project? I suppose by "Project > Add to project > Components and Controls > Registered ActiveX Controls > Windows Media Player", isn't it?
