U can use ShellExecute() fucntion n specify one of it's parameter as above file path... But again U have to expand %SystemRoot% too.
I did it that way n didnt use createprocess().
thanks anyways. Bye

Hi All,
I am trying to print postscript file using ExtEscape(), and I want check whether printer support postscript printing or not.
Please help me.
Thank you very much.

To check whether a printer supports PS, then if you have a latest MS device driver Kit (DDK), you can find a sample PS driver under
%DDKROOT%\src\print\oemdll\oemps
you can build using build -cZ command and try installing it.
Fire a print from a notepad application to the printer and check if it prints.
Hope this helps..
Thanks,
Shiva P

Thank you very much.
here my printer is supporting postscript printing it is working with java.

Hi,
I'm writing an app which has a transparent dialog SetLayeredWindowAttributes, But I need a transparent dialog witout transparent Child Windows, I mean not a transparent button, text, combo, ... .
Is there any idea? link ?
Thank you in advanced.

SetLayeredWindowAttributes tkes a HWND, can you pass in th HWND of the controls to set them to be solid ?

I tryed it before, but unfortunately when the HWnd is a handle to a child window It does not work. (however SetWindowLong works!)
Thankyou, at least one cpian (wow a MVP) answered after 2 times of trying.

Easy answer: You can't. SetLayeredWindowAttributes() only works for top-level windows, and effect all children.
A solution: You can use two dialogs, and carefully keep them positioned so that one is always directly above the other. Set the "bottom" dialog to be translucent, set the window region of the upper one to clip out everything except the controls (you could also use SetLayeredWindowAttributes() with a color key to accomplish this). You'll then see past the (fully-visible) controls through the translucent background to whatever is behind them.
Another solution: Draw the entire dialog yourself using UpdateLayeredWindow() (perhaps sending WM_PRINT messages to render the child controls). This is the most flexible, you can have varying alpha across the window. It is quite likely the most work as well.

Hi,
Thankyou. Get my 5!
I have been thinking to answer 1 but personally, did not like it!!
Solution #2 might be a better approach, however I've not been working with UpdateLayeredWindow yet!! I know something of WM_PRINT, I used it before in my codes ( for a better alpha blending ). If you have time, would it be possible to describe the process more clearly! (How should I render child controls?)
Thank you. Thank you very much, indeed.

I wish i could give you a more complete answer, but while it's something i've put a bit of thought into, i've never gotten around to actually trying to implement it (the second solution, that is). The idea is, all the standard controls will respond to WM_PRINT by rendering themselves into the specified device context. If you can detect (or correctly predict) when they need to be redrawn, you can maintain an offscreen bitmap containing the current appearances of all the children, and use UpdateLayeredWindow() to update the screen with this. In practice, it would probably work better with some controls than with others.

Dear Mr. Shog9,
Hi!
Thank you very much to have this kindness, you helped me alot. At least I have a clue to follow now and in my humble opinion It's value is times and times more than these 5's (votes).
I think finding code proect has been a great chance in my life 
Best regards.
[I've read some of your articles, they are nice. I'm engaged with writing an article at the moment.My first one!! Pray for me, Please!!]

I've fought my way through to building DCMTK, which is a cross platform DICOM toolkit that I am suddenly saddled with. Now I try to build my main project, which uses it, and I get these linker errors:

Both my project and the toolkit are compiling as multi threaded. The work I'm doing is introducing the STL to this code, removing headers like iostream.h, etc.

Hi,
Do you have any other libraries, which is linked with your application? We faced similar issues long time back..
I am just sharing what was our problem and how did we fixed it. It might help you..
We have a MFC application which is compiled as a Single threaded model..
You can see this in Visual Studio 6.0 MSDev Project Setting-->C/C++ tab-> Category : Code Generation and Use runtime library combo button..
WE had another library which is mistakenly set as Multi threaded library and linked with our MFC aplication..
Hence the application has two versions of standard librarires, one is for single threaded and another one is for multi threaded.. So the ambiguity hence linker error.
What you can do is Check for "Use Runtime Library" options for your every C++ library you are using, your project etc...

Totally a wild guess, but what if you try linking statically?

You mean link statically to MFC ? I can't see any options for static linking ( VS2005 )

To whatever, MFC, the CRT.... it's just a guess, since I don't have VS2005 installed (I have the DVD right in front of me, but I guess that doesn't help much  ).

Christian,
I just created a MFC project with VS2005 and at the bottom of the "Project" menu the last item has the project properties. The MFC option is under "Configuration Properties" -> "General".

It means a call to the Kernel32 dll, I believe. Something you don't have source for. ( You have the MFC source, you see ).

The CWnd class wraps a Win32 message loop, MFC is just a Win32 wrapper, after all.

CWnd::OnWndMsg
That looks suspiciously like the place that Windows messages end up.

I need to update a global variable that gets manipulated in InitInstance() and a wrapper function. The variable is initialized to FALSE in the main constructior but gets set to TRUE in the wrapper function. Both threads are reading the variable in InitInstance causing a race condition.
How can I grant priority to the thread that belongs to the wrapper class? I created a mutex in the main constructor for all threads to access. In the wrapper function, I have the following code:
STDMETHODIMP CWrapper::StartApplication(DataNotificationType notifyType, VARIANT data)
{
HANDLE openMutex;
openMutex = ::OpenMutex(0, FALSE, "notify");
DWORD dwMutexErr = GetLastError();
if (dwMutexErr == ERROR_FILE_NOT_FOUND)
AfxMessageBox("cannot open mutex");
else
{
WaitForSingleObject(mutex_handle,INFINITE);
variableToUpdate = TRUE;
}
....execute some program.exe....
ReleaseMutex(mutex_handle);
}
BOOL CMainApp::InitInstance()
{ .....
if (variableToUpdate)
{
....code...
}
}
Thanks!
