Steve,
I'm not sure if you are asking how to change it to something else, or remove it. I'm assuming that you know that it says "Untitled" until the initial document is named while saving. This snippet below tells you how to remove the filename (or 'Untitled') from the Window title
I dug this up from an old copy of the MFC FAQ I had kicking around:
Override the PreCreateWindow() function in your MainFrame class and do the following in it..
cs.style &= ~FWS_ADDTOTITLE ;
You can also set the initial window position (cs.x, cs.y, cs.cx, cs.cy) this way and change your class (cs.lpszClass) this way! Remember to call CFrameWnd::PreCreateWindow at the end...

Sam, thanks. I tried the link at www.stingray.com/mfc_faq but it seemed to be broken, I'm happy to find this again in the MSDN.

The document name can be changed using CDocument::SetTitle. Also see: http://support.microsoft.com/support/kb/articles/q129/0/95.asp

Does anybody have an advice on how to first locate which drive on a Windows 2000 system is the CD-ROM drive and then how to execute a file on the CD-ROM (the file name is known). I cannot use a CFileDialog in order to have the user specify the drive and file name, it must be done without the user seeing anything.

Hi Roger,
A simple way could be a loop from "A:\" to "Z:\" in which you call GetDriveType(). Then you may stop at the first DRIVE_CDROM result or collect all CD-ROM drives and then choose the best.
Hope this helps,
Paolo.

I have a problem setting the colors of my MFC application. I have set the background of my dialog
window with SetDialogBgcolor(); but the border is still using the system colors. How do i set the color
of the border?
Another problem I have is that the little arrow on my ComboBox is also set by the system colors, and I can't find a
way to change it.
I have a slider in my application, wich background changed with SetDialogBgcolor(); but I also want to change the color
of the thing you slide and the area witch it slides on, but I have no clue how and where to change these.
I also need to know how I change the color om my menu.
Thankful for any help =)

Hi,
Add the following code to your Dialogs OnPaint() method. If a method like this doesnt exist, you can add it from Class Wizard.
void CYourDialog::OnPaint()
{
CPaintDC dc(this); // device context for painting
CRect rect;
GetWindowRect(&rect);
ScreenToClient(&rect);
dc.FillSolidRect(rect, 0x00000000); //set bk color to black
}
I am sorry that i cannot answer your other questions.

Hello,
When you open a CFileDialog, the tree-control displays the folder that is given in the ofn.pszInitialDir string. Once opened, the tree-control displays the folder that is selected by user action.
But how do you force the CTreeCtrl to display another folder by software? I have a class that is derived from CFileDialog. But i don't succeed in making the tree-control display another folder once the dialog is running.
I hope i'm not supposed to fill-up the tree control myself, am i? Since the file dialog has all the functionality to do so. But i don't see any CFileDialog function that can be of any use.
Can someone help me with this one?
Thanx

You're talking about thousands, if not tens of thousands of lines of code. This isn't a simple proposition. I'd ask yourself if the effort necessary is really required, and if it is, then you best go looking into OLE because that's what drag-n-drop is connected to.

If you want to use a modeless dialog then extend your window from CDialog. Here is an example:
CShowMessage *swRem=new CShowMessage();
swRem->Create(IDD_SHOWMESSAGE_DIALOG);
swRem->ShowWindow(SW_SHOW);
Here CShowMessage is a CDialog created by 'New Form' menu that is located in 'Insert' menu. If you want to make it modal just write the following code:
CShowMessage swRem;
swRem.DoModal();

See http://home.socal.rr.com/samhobbs/VC/ModelessDialogs.html for my notes about modeless dialogs.
Unfortunately, what you have here is not a modeless dialog. It is a window that is not a dialog, so Mustafa's reply is also relevant. The easiest solution is to create a dialog as he suggests, and perhaps my notes will help you to show it successfully.
If you wanted to, though, you could create a window and then create a static control in it, but I think it would be best to use a modeless dialog first, then get fancy later. You could use CMiniFrameWnd for the window, though.

Is it possible in Microsoft Visual C++ to get the build number of an application (e.g. to display it in the About dialog)
Best regards,
Peter de Hon
|
|
|
|
|
Look at documentation on GetFileVersionInfo(), GetFileVersionInfoSize() and VerQueryValue() (to retrieve a VS_FIXEDFILEINFO structure).
I never did it to retrieve the build number, but I suppose you have to find out which are the corresponding bits in the FileVersion or in the ProductVersion.
Hope this helps,
Paolo.

Env: Vis C++ 6.0 SP3 WIN98 updated.
Doc/view application under debug.
I have a class constructed with CW that consists of standard variable declarations, an array of records of byte arrays that accept serialization and is included in this class, etc.
In the wiz constructed document class, I create this class object with the new operator from within the document constructor:
MFDPreFileDoc::MFDPrefileDoc()
{
CMFD_RCRD* pCMfD_RCRD = new CMFD_RCRD();
}
All works well with the app (static linked exe), pointers, etc.
Under debug, if the app (SDI or MDI) is closed with exit, no problem. Id the app ic closed with the mainframe "X", debug dumps a mem leak error pointing to this new statement.
The CMFD_RCRD has a virtual destructor as does the document itself created by the WIZ. I have tried placing a function in the doc destructor pointing to the CMFD_RCRD destructor, but get an assertion err.
Within the app, there are no errors associated with closing child win views associated with their instances of the relative document instances as indicated by debug, only with the mainframe X end app.
Any ideas? Do I have a real mem leak or is this due to the debug environment?
|

Looks like a real leak - once the constructor exits, the app will have no way of deleting the object.
The different behaviors you describe on closing are puzzling. If a document is opened or created, this should leak.
Try a more standard approach? Declare
CMFD_RCRD* m_pCMFD_RCRD;
as a doc class member, call new in the doc constuctor and delete in the destructor, and this 'strange yet puzzling' feature should go away.

Hi,
I just want to guess a solution. I dont know if it works or not.
In the destructor
<br />
delete this;<br />
I hope it works.
