Thank you very much. That is my missing link.

Use CreateProcess() and keep the handle around. If the handle is NULL, don't let the program be executed again.

James thanks, This turns out to be messy. I couldn't figure out how to put the command (with full path?) once and for all into the command line. Up would come a message box and if I have to enter full path each time, I might just as well attach to a process. Up until now I've always used c++ and it was simple to put the break point in the calling routine and then just step into the routine under the dll. With java I first thought maybe I could use a get character from keyboard to trap it and then attach to the process, but then I remembered the old int 3, which may do the job for me. (In any case I have to recompile the dll with a one line change when I want to debug it.) Int 3 is now __debugbreak(), but it does the job. Up comes a message box telling me my program has crashed and if I want to send a report to Microsoft? There is a debug button which allows me to attach a debugger, which is what I wanted to do in the first place. In short, this looks like the easiest solution. You asked me to reply if your suggestion helped. I couldn't reply so long as I didn't have a solution. You should be aware that even your offer to help is of great value. It gives additional thought for consideration which is always of great value when you are stuck with only your own way of thinking. So, if you helped? I think the answer is always YES! Thanks. Ilan

ID_FILE_OPEN is not a message, it is a command. One could get away with posting a WM_COMMAND message with ID_FILE_OPEN as the menu item. PostMessage(AfxGetMainWnd(), WM_COMMAND, MAKEWPARAM(0, ID_FILE_OPEN), 0); You may be right I may be crazy -- Billy Joel -- Within you lies the power for good, use it!!!

Thanks for your kind answer.

Alex, I am really impressed. I want to thank you for pointing out the code to me. I was just thinking of making a simple graph with some text and wanted to avoid reinventing the wheel. This isn't a wheel but the whole automobile! I see I can use it in c++, so I'll use it there as well. My trivial question in Visual Basic turned out to a super answer. Ilan

quite right. I think you need to override CStatic class to use in you app. Prasad Notifier using ATL

I decided that your method was SO much nicer that I would throw out what I did and use your method. Just for general education if you happen to know how I would capture the WM_PAINT for the static control, it would be nice to know. In any case, I will no longer pursue it so it is of minor importance. I threw out the WM_PAINT message, threw out the invalidateRect and I just call it once. It turns out that I need an initialization routine for setting up the radio buttons depending upon the study type. It was most natural to just call my routine from there (like your WM_INITDIALOG suggestion). My code is simpler now: void CMyToolbar::SetPatInfo(void) { // font size can start at 16 if 3 lines are permitted. // start with font size = 12 for 4 lines. int fontSize = 120; int i, j; CFont hFont, *hOldFont; CWnd *wnd1; CSize sz1, sz2; CRect rc1; CString textOut[4]; CDC *pDC; CCardiacDoc *pDoc; CCardiacView *vw = CCardiacView::GetView(); pDoc = vw->GetDocument(); textOut[0] = pDoc->m_patName; if( textOut[0].IsEmpty()) return; textOut[1] = pDoc->m_patID; textOut[2] = pDoc->m_imageData[0].m_acqDateTime.Format("%d-%b-%Y"); textOut[3] = pDoc->m_styName; if( vw->m_masterFlg <= CCardiacView::VW_CARDIAC_DISP2) textOut[3] = "Myocardial Perfusion"; wnd1 = GetDlgItem(IDC_PATINFO); pDC = wnd1->GetDC(); sz1 = 0; for( i=j=0; i< 4; i++) { sz2 = pDC->GetTextExtent(textOut[i]); if( sz2.cx > sz1.cx) { sz1 = sz2; j = i; // j will be the maximum string } } wnd1->GetClientRect(&rc1); wnd1->SetWindowText(textOut[0] + "\r\n" + textOut[1] + "\r\n" + textOut[2] + "\r\n" + textOut[3]); sz1.cx = rc1.right; sz1.cy = rc1.bottom; while( fontSize > 80) { hFont.CreatePointFont( fontSize, "Ariel", pDC); hOldFont = pDC->SelectObject( &hFont); sz2 = pDC->GetTextExtent(textOut[j]); // the longest one if( sz2.cx <= sz1.cx) break; // found a size pDC->SelectObject( hOldFont); DeleteObject( hFont); hFont.Detach(); fontSize -= 20; // reduce font size by 2 } wnd1->SetFont(&hFont); hFont.Detach(); ReleaseDC(pDC); } I have a question about DeleteObject(hFont). Do I need it in my loop if I use hFont.Detach()? I noticed you didn't use it in your example, so I also didn't use it when I found the font I wanted. Will I add garbage if I change the patient to a new patient? Thanks again, Ilan

IlanTal wrote: Should I use Dispose() at the end of the button routine? You can call the Dispose() method when you no longer need your class. If you call it at the end of your button routine you'll throw a null reference exception if you try to make use of the class later in another sub as you cannot access a disposed object. A basic use of the Dispose() method in your click event would be something like Option Strict On Public Class Form1 Dim myScope as ScopeClass 'declare the class Private Sub Test_Click(...) 'create new ScopeClass instance myScope = New ScopeClass 'do whatever the ScopeClass needs to do 'call other methods/functions etc ...... 'ScopeClass is no longer needed, 'all processing that needed to be done is complete myScope.Dispose() End Sub End Class Because of the automatic garbage collection of the .NET framework you don't HAVE to call Dispose() but it can be used to manually reclaim memory.

IlanTal wrote: It doesn't recognize 'this', but on the other hand it knows what 'Me' is. Likewise it doesn't know what 'Form1 mainForm' is but it does know what 'ByRef mainForm As Form1' is. Right. I'm only programming C# myself, so I mixed up the syntax a bit. Sorry for that. There is no reason to specify ByRef for the reference, though. You are not going to replace the main form with a completeley new form in the method, are you? IlanTal wrote: Do you know if I could save the value of mainForm in my class in case I need it outside of the Init function? I could make it a class variable, but the question is if it could change? My gut feeling is that it wouldn't change since it is the main form. Yes, you could. The reference to the main form won't change as long as the form is open. However, as I suggested before, I reccommend that you just send a reference to the control that the method is going to change. That way it's obvious what the method is going to update, and as the method isn't locked to a specific control you might be able to use the method for more than one control. --- b { font-weight: normal; }

I found the problem in WinBase.h. It has #ifdef UNICODE #define CreateDirectory CreateDirectoryW #else #define CreateDirectory CreateDirectoryA #endif // !UNICODE I added #undef CreateDirectory and it now compiles.

Now, thanks to this board, I know it is a problem with managed extensions. When I started, it never occured to me that the problem could be there.

As usual, searching CodeProject articles is a good place to start - there is an article called "A simple interface to the Video for Windows API for creating AVI movies from individual images" (and here's the link: http://www.codeproject.com/audio/aviutil_.asp[^]) I have no idea how well this article works - it didn't get a great score, but it may give you some tips.

Oops, I didn't see other replys just now. Obviously, my suggestion is the worst one. hehe, ignor it. Regards, Chris

As an aside, i ran into this earlier this week in a WinCE (PocketPC 2002) app i was working on. I found that calling CWnd::GetFont() for a CDialog window always returned NULL. Turns out this is expected (from MSDN WM_GETFONT for WinCE): The WM_GETFONT message does not return a font handle if the message is sent to a dialog box created by the DialogBoxParam, DialogBoxIndirectParam, CreateDialogParam, or CreateDialogIndirectParam functions. ...cmk Save the whales - collect the whole set
