I'm using SHFileOperation to delete folders, as shown in the following code. However, there seems to be a problem with spurious "file in use" errors when I call this function on most folders in my system. These directories don't have any special properties that I can see via browsing, so I can't understand when the command fails.
Is there some catch or trick in this? Win2K, SP1, VC++ 6.
Thanks -
Jim
// Get the path
TCHAR szOldPath[_MAX_PATH];
ZeroMemory(szOldPath, sizeof(szOldPath)); // SHFileOperation requires a double-null terminator
SHGetPathFromIDList(m_pidl, szOldPath);
// Set up the file op
SHFILEOPSTRUCT fileOp;
fileOp.hwnd = AfxGetMainWnd()->GetSafeHwnd();
fileOp.wFunc = FO_DELETE;
fileOp.pFrom = szOldPath;
fileOp.pTo = "\0\0"; // NULL;
fileOp.fFlags = FOF_ALLOWUNDO | FOF_NOCONFIRMATION;
fileOp.fAnyOperationsAborted = FALSE;
fileOp.hNameMappings = NULL;
fileOp.lpszProgressTitle = NULL;
return(SHFileOperation(&fileOp) == 0);

I found the problem...
.. I had neglected to call Release() on an IEnumIDList that had been created to look at the folder contents. This marked the folder as in use. That was a fun one to trrack down!

About:

And all other things about it ...
Thanks

ATL 3 now becoms ATL 7... It includes new features like Aggregation accros process boundaries. I didn't had the chance to experiment with it yet...
Another thing is of-course the ease of work with VC7... The user interface includes filetabs, code collapsing, and so on...
But I think the biggest change will be the managed extensions you can use (If this is an advantage, I have yet to find out)...

Hello,
I’m trying to write 3 strings out to a text file but I need each string to be on a separate line.. Here is what I have tried..
CFile fileEditText;
if(fileEditText.Open("c:\\text.txt",
CFile::modeCreate + CFile::modeWrite))
{
//Write out the full string
fileEditText.Write(
strFirstline+"\n\r"+strSecondline+"\n\r"+strThird+"\n\r",length.GetLength());
//Close the file
fileEditText.Close();
}
I've tried every combo of "\n" "\r" etc..
It still writes out the 3 strings in one continuous line in the text file..
Any help would be appreciated.
THANKS,
Rob

It's \r\n, not \n\r.  You can also use CStdioFile, and then put just \n in your strings. CStdioFile::WriteString() automagically converts \n to \r\n for you.

Is Easy.
CStdioFile fileEditText;
if(fileEditText.Open((LPCTSTR)("c:\\text.txt", CFile::modeCreate | CFile::modeWrite))
{
strFirstline += '\n';
fileEditText.WriteString(strFirstline);
strSecondline += '\n';
fileEditText.WriteString(strSecondline);
strThird += '\n';
fileEditText.WriteString(strThird);
fileEditText.Flush();
fileEditText.Close();
}
Cheers!!!!

Can anyone tell me how to remove the standard MDI window list in a CMDIFrameWnd ???

Ensure that your menu has none of the following items:
ID_WINDOW_NEW
ID_WINDOW_ARRANGE
ID_WINDOW_CASCADE
ID_WINDOW_TILE_HORZ
ID_WINDOW_TILE_VERT
ID_WINDOW_SPLIT
MFC searches through your menu (in CMDIChildWnd::OnUpdateFrameMenu) and uses the rightmost popup containing one of these items as Window menu - the one that gets the window list.

I don't even have a Window menu... MFC places it on the bottom of my second-last menu... Even if this menu's name is "Test" for example... and my menu items names "Test1", "Test2", ... The Window list is put always on the bottom of them...

Do you understand the difference between menu item name and menu item ID? Changing the names will not help. If you have menu containing items with identifiers like ID_WINDOW_xxx, the window list will be appended. You have to change menu item identifiers.

I do! I don't have a menu which has an ID that starts with ID_WINDOW_ ... As a matter of fact, MFC puts the window list on the "Test" menu's bottom... Which has the ID's: ID_TEST_TEST1 and ID_TEST_TEST2. My Child windows are created through the CMDIChildWnd class' Create method...
CSettingsDlg m_settDlg; // Derived from CMDIChildWnd
m_settDlg.Create(AfxRegisterWndClass(0, 0, (HBRUSH)COLOR_WINDOW), title, WS_CHILD | WS_VISIBLE | WS_CAPTION | WS_MINIMIZEBOX | WS_SYSMENU, r);
m_settDlg.ShowWindow(SW_SHOW);

Put the breakpoint in the line 871 of the file WINMDI.CPP located in vc98\mfc\src directory. The line contains this code:
return hMenuPop;
If your programs stops there, it means one of the following:
1) your menu has some ID_WINDOW_xxx id.
2) your ID_TEST ids have the same value as ID_WINDOW_xxx ones.
If breakpoints is not hit and you can see window list in your menu, something strange is going on...

The debugger doesn't even stop at the start of this function... It is never executed! And my ID-values are different  I think I'm going crazy here

Did you override CMDIFrameWnd::OnUpdateFrameMenu or CMDIChildWnd::OnUpdateFrameMenu in your program? Or maybe you're explicitly calling CMDIFrameWnd::MDISetMenu?

Nope, non of these three... If you have a few seconds time, I have send you a VERY small test-case (created within a few minutes from scratch using the MFC wizard) by mail (If you're upset for this, I'm sorry, but I'm quite desperate)...

OK, that was easy. Your app doesn't use doc/view architecture. To disable window menu, override OnCreateClient in your CMainFrame class, and put the following code inside:
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
return CreateClient(lpcs, NULL);
}
Just pass NULL as second parameter to CreateClient - this means that you don't want the Window menu.

Can you please tell me how to hide/delete the window popup menu from the main menu if I am working with Doc/ View application? Thats really urgent, I am using the code like
CMenu *menuVault = this->GetMenu();
::DeleteMenu(menuVault->GetSafeHmenu(),9,MF_BYPOSITION);//9 is the position of Wondows menu
::DrawMenuBar(::AfxGetMainWnd()->m_hWnd);,
everything seems to be ok but menu bar is not getting refreshed or redrawn..... what could be worng????
Never complain,never explain,just do your work.

As a CTreeCtrl is expanded and contracted, the area covered by the tree varies. Anyone know how I can find / calculate the size of this area. I don't just want to know the area of the CTreeCtrl window, but the area covered by the actual tree. Anyone got any ideas please?
I'd like to modify some of the code on this site which is a drop down ctreectrl, but the drop down window is of fixed size. I'd like to make the drop down window vary in size according to the size of the actual tree.

Seems that you have to do this 'manually' - there's no single function.
1) call CTreeCtrl::GetFirstVisibleItem. The name says it all
2) in the loop, call CTreeCtrl::GetNextVisibleItem until it returns NULL. For each item, determine its rectangle using CTreeCtrl::GetItemRect. UnionRect will combine items' rectangles into one.
