I'm not sure where you're headed here. You've got a formview (fair enough ) and you're trying to call DoModal on it ? You can have your formview, but if you want a modal dialog, you will need to create a dialog template, even if it's the same as the one for the formview, and derive a class from CDialog by double clicking on the form and creating a class. This class you can call DoModal on, you cannot do this to a formview, as you have discovered.

hi,
i want to move a dialog based window. this isn't a problem but i do not
want to redraw the dialog along the way, but a rectangle with the size of
the dialog. This results in faster drawing. I tried to return HTCAPTION whenever
i received a WM_NCHITTEST message but the drawing speed left a "trail", that's
why i want to use the rectangle outline.
However i don't succeed in doing this. I have to work with the fullscreen dc
because my app is a dialog and thus the main window.
How do you fill the screen dc again or better delete/restore the space previously
occupied by something else for instance the dragging rectangle and then redraw the rectangle?
Is there any sample code that uses a rectangle to show the new windows position instead
of immediately redrawing the window being moved?
thanks

Why don't you handle the behviour you want in OnPaint and let Windows worry about redrawing ?

Because the redrawing is far from optimal when i use a non rectangular region on my dialog. I even use an offscreen dc to hold the bitmap and so on but when i quickly move the dialog, it leaves a trail behind.
The only way to avoid that is not drawing the window but drawing a rectangle for it's new position when moving and only actually redrawing it at it's new location when the left mouse button was released. You only need to draw a rectangle instead of the whole window that way.
If you know of a more efficient way of drawing, i'll gladly listen because i'm out of ideas and i can't use direct x to draw more efficient.

Yes, but, like I said, if you actually set a variable to tell you if you're dragging, and have two draw methods ( one that draws the dialog normally, and one that draws the outline ), won't that mean Windows will handle the rest ? Dragging a dialog is not normally a problem, so even if you suspend drawing operations while you drag you will surely get what you're after, in that you won't get trails, etc. ?

i tried but i don't succeed in doing this.
looked like a valid method. i'm really annoyed by this.

Calling SystemParametersInfo(SPI_SETDRAGFULLWINDOWS, FALSE, NULL, 0) when initializing dialog based window.

If you modify the class bits of your dialog window that you are dragging over the main window with the CS_SAVEBITS sytle, windows will save the bitmap image that is below your dialog, and when you drag the dialog, windows will automatically replace that region with the bitmap that it cached.

Can the file size exceed 4G in a FAT32 system?
Thanks.

I believe so, but it depends on the API you use to create it. Be careful though - creating a file does not mean you can use it. For example, I used a video ripper that allowed me to create an AVI greater than 2 Gig, but nothing would play it, or load it to convert to MPG.

Thanks my pal.
If I use "CreateFile", is there still a size limit?
Best regards.

I *think* so, but I know from reading here, not from doing it myself.

In the "OnCreate" funtion of the class "CInPlaceFrame" of a Server Application, there is a statement like this "m_dropTarget.Register(this)". Here are the comments from Microsoft:
// By default, it is a good idea to register a drop-target that does
// nothing with your frame window. This prevents drops from
// "falling through" to a container that supports drag-drop.
I can not see the funtion of the statement. If I remove the statement, my server application runs like before.

Thanks.

It depends on the container that is containing your Frame window. You may write a control that is supposed to work in one way, but because the control frame window does not act like a catch all for drop actions, the container window may change the behavior of your control. It really all depends on the container window.

It is well known that the data member "m_pDocTemplate" points to the CDocTemplate that owns the Document.
But in the CDocument::CDocument(), "m_pDocTemplate" is assigned a "NULL" value.
How does the "m_pDocTemplate" get its own value?
Thanks.

I've written an ATL dialog class CAddComputerDialog, which looks like a windows computer search dialog (e.g. in regedit where you can connect with another computer's registry). If you're interesting, I will mail you the files.
You also can search for a computer with the shell dialog "SHBrowseForFolder". This dialog can be configured to display computers only.

Use following APIs:
BeginPath, EndPath, PathToRegion, SetWindowRgn
and shape functions.

CFile myfile ;
LPCTSTR lpszFileName = "myfile.dat" ;
myfile.Open(lpszFileName,CFile::modeReadWrite) ;
It is safer to use this function within a TRY CATCH Block
Read or write using the CFile function
CFile::Read or CFile::Write
Close the file using CFile::Close;)
