Okay, MIke.
But here is one more question!

Say I am writing a console based app [NT service] that uses MFC. Now can I use _beginthreadex to start my worker threads and expect to use MFC functions safely?

Use AfxBeginThread() to start them. Smile | :)

CListView

Hallo,
can anybody help me with CListView class?

1) I can use only one column with width on all view window. Problem is with scroll bar. I get the size of scroll bar in CListView::InitDialog using GetListCtrl().GetScrollBarCtrl()->GetWindowRect(). But at this time is not scroll bar known. So what is the good way?
2) I can't select any row in list control. I filter callbacks on mouse click but how about keyboard click?
3) I can't show header. I used GetListCtrl().SetExtendedStyle(LVS_NOCOLUMNHEADER); in the CListView::InitDialog but it has no effect.

Thanks, Alex.

I have been looking at this to I find this very annoying. If you don't have a header (unless you have more that one column or it won't work) don't insert a column and the only what it should scroll is if the contents is wider that the view.

Hopefully I was helpful or somebody has a better suggestion.

1) I'm not sure I understood your question, but seems what you're after is calculating the width of the view minus the width of the vertical scrollbar so that you can adjust the column to its maximum extent without the horizontal scrollbar appearing. Am i right? If so, ::GetSystemMetrics(SM_CXVSCROLL) might be what you're looking for.

2) I don't quite understand your question. Sorry.

3) LVS_NOCOLUMNHEADER is not an extended style. Use GetListCtrl().ModifyStyle(0,LVS_NOCOLUMNHEADER,TRUE) instead.

avoiding multiple instances

I'm using the code from following posting to avoid running multiple instances of my app. I'm running an MFC SDI application. Where is the ideal location to create and release the mutex?

I've seen a few examples to avoid multiple instances of an application. In fact, there are a few of them here on code project. However, they all seem like a lot of code, when there is an easy solution like:

HANDLE hMutex = CreateMutex( NULL, TRUE, "MVD Load Utility" );
if( (hMutex == NULL) || (GetLastError() == ERROR_ALREADY_EXISTS) )
{
AfxMessageBox( "Two copies of this program are not allowed to run at the same time." );
return FALSE;
}
