Depending on how you use CreateProcess() there's different ways to do it. In one of the parameters you write something like notepad.exe, just write notepad.exe c:\\test.txt or whatever you call your document then notepad should open it...

I used this code:

STARTUPINFO si;
PROCESS_INFORMATION pi;
memset (&si, 0, sizeof (STARTUPINFO));
memset (&pi, 0, sizeof (PROCESS_INFORMATION));
si.cb = sizeof (STARTUPINFO);
si.dwFlags = STARTF_USESHOWWINDOW | STARTF_USESTDHANDLES;
si.wShowWindow = SW_SHOW;

CreateProcess("c:\\WINDOWS\\notepad.exe c:\\My Documents\\test.txt",NULL,NULL,NULL,NULL,
CREATE_DEFAULT_ERROR_MODE,NULL,NULL,&si,&pi);

????It doesn't work?

Try with CreateProcess("c:\\WINDOWS\\notepad.exe \"c:\\My Documents\\test.txt\"",NULL,NULL,NULL,NULL,
CREATE_DEFAULT_ERROR_MODE,NULL,NULL,&si,&pi);

You have problems with My Docuements, I found the solution converting to ShortPath.

You must to execute with C:\\windows\\notepad.exe C:\\My documents\\test.txt

But C:\\My documents\\test.txt must be used with short path, because the application found a space between My and Documents.
For convert use GetShortPathName(). Or put the test.txt field in other directory without spaces...

Use ShellExecute() instead, which will automatically run the app associated with .TXT files.

You should be able to include the file name you want opened on the command line parameter (2nd argument in CreateProcess).

e.g. "notepad.exe c:\test.txt"

Hope this helps,

get a pointer to the document

Help me please
I am not able to find my semantic error
I want a pointer to the document (MDI, Doc/View) in the application class.
I tried this way:
void CMyApp::OnFileNew()
{
CWinApp::OnFileNew();
CMainFrame *pFrame = (CMainFrame *)AfxGetMainWnd();
CMyDoc* pDoc = (CMyDoc*)pFrame->GetActiveDocument();
pDoc->SetModifiedFlag(); //Error: Access Violation!!!!!!!
}
Why is pDoc not a pointer to the active document??????

Any suggestion would be very appreciated
thanks in advance

I have'nt tried the solution you suggest, and I don't know why it fails. But since the document has nothing to do with the frame class, you should obtain it from the Application class. Copy and paste this code into you CMyApp class:

CCommixDoc* CCommixApp::GetActiveDocument()
{
	POSITION pos = GetFirstDocTemplatePosition();
	ASSERT(pos);

	CDocTemplate* pTempl = GetNextDocTemplate(pos);
	ASSERT(pTempl);


	pos = pTempl->GetFirstDocPosition();
	ASSERT(pos);
	if (pos==NULL)
	{
		return NULL;
	}

	return (CCommixDoc *)pTempl->GetNextDoc(pos);

}

Hi christian
thanks a lot. I have tried your solution and it works in this case very good
My aim is to open several documents with the belonging childwindows depending on a loop in a global function. And fill the data member of the document class
When i try your solution in the global function:

CMyApp * pApp = (CMyApp *)AfxGetApp();
CMyDoc * pDoc = pApp->GetActiveDocument();

and try to fill the data member of the document class:

pDoc->m_data = x;

i get an error Frown | :-(

in your function GetActiveDocument() in the evaluation line:

ASSERT(pos);

Can you explain me this behavior?
What is my error in reasoning?

thanks in advance

If you have an MDI app you need to go
AfxGetApp()->MDIGetActive()->GetActiveView->GetDocument(); ( or possibly AfxGetApp()->MDIGetActive()->GetActiveDOcument();, but I'm not sure on that one ).

Great! fantastic! excellent!
Thank you very mutch for your suggestion
It works fine.

Some small correction:
MDIGetActive() is not a element from derived CWinApp class (CMyApp), but CMDIFrameWnd::MDIGetActive. So I insert a pointer to the CMainFrame:

         CMainFrame* pmyFrame = (CMainFrame*)AfxGetMainWnd(); 
         ASSERT_VALID(pmyFrame);


//	CMyDoc * pmyDoc = (CMyDoc*) pmyFrame->MDIGetActive()->GetActiveView()->GetDocument(); it works too
	CMyDoc * pmyDoc = (CMyDoc*) pmyFrame->MDIGetActive()->GetActiveDocument(); 

	ASSERT_VALID(pmyDoc);

thank you

SetWindowOrg() screws with my layers!

I have some code that draws a filled rectangle with a CBrush and FillRect(), changes the window origin, and then continues to draw lines with a CPen. My problem is that the lines are being drawn behind the filled rectangle, and messing with the window origin with SetWindowOrg() seems to be doing it. Commenting out my call to SetWindowOrg() draws the lines on top.

Why is it doing this?

Sorry. I found the answer in a previous thread.

"You can set a background color for selected text using RichEdit 2.0 or later. Just pass CHARFORMAT2 structure to CRichEditCtrl::SetSelectionCharFormat and set crBackColor member to whatever you want."

Toolbars supprt their own built in tooltips. You should be able to set them up as follows:

When creating the toolbar, and looking at the properties of each button, you can enter a string which is the staus bar prompt. The tooltip of the button can be entered in the format:

"Status bar prompt"\n"Tooltip"

Just set the associated text for each button.

You may need to call EnableToolTips on your toolbar to get he me to work. I have never used a toolbar in a dialog project, but it should work this way.
