What's this conversion you're talking about then ?
When you are drawing on a window, all the coordinates are relative to the upper-left corner of the client area of your window.
|

If you use a window device context then pixel coords are relative to the top-left corner of that window client area.
On the other hand, if you use a screen device context (for instance via GetDC(NULL)) then the pixel coords are relative to top-left corner of the screen.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

I think SetPixel wil change the color of the specified pixel.

If the point that you want to draw have a dimension of only one pixel, then changing the color of the specified pixel( say to black color ) will make that pixel to appear as a point isnt it?
if the diameter of the point you want is more than a pixel, you have to follow the way mentioned by Cedric Moonen.

Hi,
I have HWND of window. How can I terminate the process using HWND?

Although you can get the process id of window and call TerminateProcess() function, i dont recommand using it.
If the HWND is HANDLE to the main window of that application, seding a WM_CLOSE message will terminate the process.
|
|
|
|
|
But this methos is giving exception after closing the application so couls you tell me like Treminate process using HWND
|
|
|
|
|
Well, then you should fix the problem. Is it one of your application that crashes ?
TerminateProcess will kill the process in a brutal way, sending a WM_CLOSE message is much elegant because it lets the application do some clean-up before exiting.

1. GetWindowThreadProcessId() to get the process ID.
2. With this process id callOpenProcess() function with PROCESS_TERMINATE access.
3. Call TerminateProcess().

You dont need to use of Treminateprocess you must send WM_CLOSE for close a program.

Sounds like a university project....
Anyway, what have you tried so far ?

I need to change printer default settings. I am using DocumentProperties function. Here is my code:
if(!SetDefaultPrinter(ptiSel.sPrinter)) return false;
HANDLE hPrinter;
if(!OpenPrinter(ptiSel.sPrinter.GetBuffer(0),&hPrinter,0)) return false;
DWORD dwSize = DocumentProperties(0,hPrinter,ptiSel.sPrinter.GetBuffer(0),0,0,0);
pDefDEVMODE = (LPDEVMODE) malloc(dwSize);
DocumentProperties(0,hPrinter,ptiSel.sPrinter.GetBuffer(0),pDefDEVMODE,0,DM_OUT_BUFFER);
if(pDefDEVMODE->dmFields & DM_DEFAULTSOURCE)
pDefDEVMODE->dmDefaultSource = ptiSel.wTray;
DWORD res=DocumentProperties(0,hPrinter,ptiSel.sPrinter.GetBuffer(0),pDefDEVMODE,pDefDEVMODE, DM_OUT_BUFFER | DM_IN_BUFFER);
if(res != IDOK) MessageBox(0,_T("Could not set printer settings"),0,MB_ICONERROR);
ClosePrinter(hPrinter);
This code is based on msdn sample (http://support.microsoft.com/kb/167345). Settings are not changed. The second call of DocumentProperties retrieves valid DEVMODE structure, I change it and save back to printer, the function returns IDOK result but does not write settings to printer. Can anybody help me?

Hi,
I have a few thread questions
Would anyone know why someone would use _beginthreadex instead of CreateThread or visa versa
What is the difference between The Value return from GetCurrentthreadId and GetCurrentThread
In processing my DLL ATTACH_THREAD message I am able to get the threadid of the thread being created but not the thread
handle The GetCurrentthread API returns -1
Can I get the Thread handle if I have the the thread id
Thankx

ForNow wrote: _beginthreadex instead of CreateThread or visa versa
_beginthreadex() internally calls CreateThread for creating thread. In addition to creating thread, it will perform some CRT initializations also. So if you want to call some CRT functions inside the new thread, its better to use the _beginthreadex() function.
ForNow wrote: The Value return from GetCurrentthreadId and GetCurrentThread
GetCurrentthreadId return the current thread ID where GetCurrentThread return the handle to current Thread.
ForNow wrote: handle The GetCurrentthread API returns -1
If you call the GetCurrentthread(), it will always return 0xfffffffe. Actually this is a pseudo handle to the current thread. This value can be used only in that thread. The GetCurrentProcess() also returns a similar value - 0xffffffff.
If you want to get the correct handle value, you need to use the DuplicateHandle() function
HANDLE hRealHandle = 0;
DuplicateHandle( GetCurrentProcess(),
GetCurrentThread(),
GetCurrentProcess(),
&hRealHandle,
0,
TRUE,
DUPLICATE_SAME_ACCESS );
