I looked for WM_DISPLAYCHANGE but I couldn't find a way to add that using the wizards.

The class wizard only handles a subset of the WM_ windows messages. For ones like WM_DISPLAYCHANGE you'll have to add the code by hand.

Add into your message map

ON_MESSAGE(WM_DISPLAYCHANGE, OnDisplayChange)

And then add a function to the class

LRESULT OnDisplayChange(WPARAM wParam, LPARAM lParam)
{
// Do processing of WM_DISPLAYCHANGE here
return 1;
}

Invalidate(TRUE) or RedrawWindow(). See MSDN for details.

CFilePrevDialog::CFilePrevDialog(BOOL bOpenFileDialog, LPCTSTR lpszDefExt, LPCTSTR lpszFileName,
DWORD dwFlags, LPCTSTR lpszFilter, CWnd* pParentWnd) :
CFileDialog(bOpenFileDialog, lpszDefExt, lpszFileName, dwFlags, lpszFilter, pParentWnd)
{
m_ofn.lpTemplateName = MAKEINTRESOURCE(IDD_DIALOG_PREV);
}
-----
CString strFileDlg = "Jpg Files (*.Jpg)|*.Jpg|";

CFilePrevDialog dlg(TRUE, "Jpg", NULL,
OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_ALLOWMULTISELECT,
strFileDlg, NULL );

dlg.DoModal();
-----------------------

The simple answer is: you can't.

But you can get project paths and names and try to deduce the workspace path from them (perhaps even use CFileFind).

What do you need it for?
Maybe there is a different solution to your problem.

btw: I've written a thin wrapper library for DevStudio 6.0 interfaces. Maybe you'll find it useful. It is part of the following project: http://www.codeproject.com/macro/SmartReplace.asp

thanks for reply,

i found a code to get the dsw, it appears in one of the add ins here is code project (in the project http://www.codeproject.com/macro/restoreclassviewaddin2.asp?target=restore%7Cclass%7Cview#xxxx )

here is the code:

CString CCommands::GetWorkspacePath()
{
	CWinApp* pApp = AfxGetApp();

	CString szWorkspace;

	POSITION posdt = pApp->GetFirstDocTemplatePosition();
	while (NULL != posdt)
	{
		CDocTemplate* pdt = pApp->GetNextDocTemplate(posdt);
		if (0 == strcmp("CProjectWorkspaceDocTemplate", 
			pdt->GetRuntimeClass()->m_lpszClassName))
		{
			// found it, grab the first (and only) document:
			POSITION posdoc = pdt->GetFirstDocPosition();
			if (NULL == posdoc) break;

			CDocument* pdoc = pdt->GetNextDoc(posdoc);
			if (NULL == pdoc) break;

			// stash the workspace path+file:
			szWorkspace = pdoc->GetPathName();
			if (0 == szWorkspace.GetLength()) break;
		}
	}

	return szWorkspace;
}

the problem is this code doesn't work for me !!!
the line

POSITION posdt = pApp->GetFirstDocTemplatePosition();

returns null for posdt

i've debug the project restoreclassviewaddin2, and there it works! it returns the full path for the dsw...

can any1 help me here???

Hi,
I'm new to COM tech. My few COM experiences are just a few OLE Automation samples in MFC. But now I have a Project that will require me calling an object mtd across machine boundary.
Can I achieve this in MFC 7.0? If yes how?

Thanks in advance! Wink | ;)

As has been pointed out ( and this is where I was headed ), VC7 has a new version of ATL, and there's no reason you can't use it with MFC.

How to get Full Path of a file by just giving the file name

Hi VC++ experts,
I want to get the full path of a file(For example c:\Mytrial\Sample\Display.txt )by just giving the file name(For example Display.txt)as input

The File may be present at anyone of the drives in my PC (Any random directory path). I want to find the full path of the file by running a C++ or VC++ code from some other drive in the same PC and giving just the file name as input( For example Display.txt ) to the code.

I tried with CFileFind class without success. Any VC++ experts help me by sending some sample code.

Yes you can do it but in a different concept...
You can get what you want if the file is in the path.. But there could be a problem if more than one file with the same name is in the path.
Any way here is the sol.

1.Get the evironment string path
2.Seperate the string that are ; seperated for each path.
3.Look into that path.

While you do provide a solution to a subset of the original problem, a reliable solution is unattainable (as Michael has already pointed out).

I stand by my solution again. The original problem can not be solved as micheal has stated i agree with that. But no one had provided any solution. It can not be done is easy to answer but if you can provide solution for atleast part of the problem may be it is what the the original author of the question was looking for. Smile | :)
