Default stack size is the same for MFC apps vs console apps (1MB if I remember correctly). However with an MFC app, you'll find much more of your stack being used by MFC itself. The console app doesn't have this overhead which is why it was running OK. Also, if you're running a debug build, a lot of the stack is being used by all the debugging info.
Since you're pretty close, fails sometimes and not others, you could probably just bump up your stack size a bit and be OK. This is done via a link option, covered in MSDN here[^].
Another option would be to dump this code out into a worker thread, which will have it's own stack and won't have the MFC overhead using alot of it.

You have not loaded the rich edit DLL. This can be done by calling AfxInitRichEdit(). This is laid out in detail here.

Hi !
Our team just moved to VS.NET and we are facing some problems with the build-in debugger : very often, variables seem uninitialized in the debugger, where they actually are. This makes the debugging very difficult.
Any idea what's wrong ?
Other problem : very often, when the app crashed in a DLL it is using, the call stack is useless because it is almost empty and I cannot track back to the function which called the DLL function.
And, as aside question : would you recommend using another debugger on the Windows platform ?
Thanks for your advices,
Jerome

I've seen odd debugger issues in VC 2003 as well, and a rebuild-all of the solution has always cured them.

Hey all,
I am trying to get the page size of the page and then printing certain words on the page.
This is what I have so far.
<br />
<br />
CPrintDialog dlg(FALSE); <br />
CDC dc; <br />
#if 0 //Show print dialog. <br />
if (dlg.DoModal() == IDCANCEL) <br />
return; <br />
dc.Attach(dlg.GetPrinterDC());<br />
#else //Don't show print dialog. <br />
PRINTDLG prtDlg; <br />
AfxGetApp()->GetPrinterDeviceDefaults(&prtDlg);
dlg.m_pd.hDevMode = prtDlg.hDevMode; <br />
dlg.m_pd.hDevNames = prtDlg.hDevNames; <br />
dc.Attach(dlg.CreatePrinterDC());<br />
#endif <br />
dc.m_bPrinting = TRUE;
<br />
dc.GetDeviceCaps(LOGPIXELSX/LOGPIXELSY); <br />
<br />
CRect printArea;<br />
printArea.SetRect(LOGPIXELSX/3, LOGPIXELSY/3, dc.GetDeviceCaps(HORZRES), dc.GetDeviceCaps(VERTRES));<br />
<br />
CString str("Delayed Entry");<br />
dc.DrawText(str, printArea, DT_NOPREFIX | DT_WORDBREAK);<br />
<br />
<br />
It is printing, but not where I need it to print. Am I doing it wrong or is there something I am missing?
Thanks

Hello,
I wanted to know how one can handle an installation of the application only once.
I mean to say that, if a software has to be installed on a system, then it can be installed only once on that system and if a person tries to install it on another system then that person should not be able to do it.
I hope the problem which I have mentioned is clear and hope to hear for a solution at the earliest. I would like to have a solution either in VC++ or VB and would also appreciate if there is a sample program to guide me.
Regards,
Mythri

I know of no easy way to do this. A remote possibility would be to extract some sort of unique identifier from the machine and hardcode that into your application. The installation would then be limited to that machine only, since no other machine would have that same number.
Since the program might be installed from a CD, you can't alter the state of the .exe file.

Hi All
I have some problem in dialog box application.
I insert two dialog box namely Dialog1 and Dialog 2. Dialog1 contains a command button (Click).Dialog2 contains static text(“Hello Word”) and add member variable m_Hello of CStatic type.
I know “How to call dialog box on pressing the Click command”.
I would like to know that When I press Click button on a dialog1 then second Dialog2 should be called and static text should be hide on dialog2.
What should I write a code on the Click button.
I wrote code on the click button something like that
void Cdialog1::OnClick()
{
// TODO: Add your control notification handler code here
Cdialog2 dlg2;
//m_.ShowWindow(SW_HIDE);
m_Hello.ShowWindow(SW_HIDE)
dlg2.DoModal();
}
Any help is appreciated.

Hello,
you must do the hide action in the OnInitDialog function from dialog2 ( use class wizard to add this function)
|
|
|
|
|
If the static control on the second dialog is just going to be hidden once the dialog is instantiated, why bother showing it in the first place? Is there going to be some sort of mechanism on the second dialog that could potentially unhide the static control.
Rajesh_K_Sharma wrote:
m_Hello.ShowWindow(SW_HIDE)
This will not work because m_Hello does not belong to Cdialog1. The compiler no doubt pointed this out.
If the second dialog is modal to the first, there is no way the first dialog can communicate with the second dialog once DoModal() has been called.

1. I created an SDI application with Document/View support.
2. I added a COleDropTarget to the main view
COleDropTarget m_DropTarget;
3. I added this in OnCreate handler of the main view
m_DropTarget.Register(this);
It should have worked. Unfotunately, DropTarget.Register(this) returns FALSE. WHY???  Please help!!!

Is it possible to flatten multiple memory bitmaps into one device context? I just spent the whole day writing a class for layer management, where you can create as many layers as you like, then address them by name and draw to them, and when your all ready, call one function and it bitblt's all the layers into the dc of your window. The only problem is after I wrote all the code, I realized that the memory bitmaps have a black background, and when you bitblt one bitmap onto another, it just replaces what was there before. is it possible, or did I just waste my whole afternoon?

Sounds like a good candidate for TransparentBlt()

My directory always get much temporary files after compiling. I always need to pick source files (like *.cpp, *.h etc) one by one when I want to copy them to another folder or backup them. It's so pain 
Fortunately, I found a program today, it's very useful to me, maybe it's useful to you too. It can copy or clean specfied type of files and integrate with Explorer, very easy to use.
It's name is Clean Now！(http://www.liuxz.com/cleannow/index.htm) I have installed it in my computer and feel good  Usually, I develop with VC6 and C++Builder 6. So I create my own "File Group" like following:
VC 6 Source Files: dsw;dsp;cpp;c;h;hpp;def;clw;lib;opt;rc;ncb;
CBC 6 Source Files: h;hpp;cpp;c;lib;dfm;res;bpr;bpg;
Now, it's very easy to copy my source files to another folder or backup them without garbage: (1) Right click at my source folder (2)Move mouse to "Copy"->"VC 6 Source Files" (3) Select a destinition folder. After a few seconds, all source file and only source files will be copied to destinition folder. I don't need to pick them manually anymore!
If I don't want to copy them out, I just select "Clean"->"VC 6 Source Files", and HOLD SHIFT while clicking. All files EXCEPT source files will be deleted. My source folder become clear
You can try it out if you have interest

Here is another one. It also shows how to create a disk cleanup handler with source code.

hai,
In my module, i've 2 multiline edit box, 2 control buttons for send and receive,1 check box.
Here, in 1 editbox i've to give characters and by clicking send control button, store that value in a temporary variable.
By clicking receive control button, i've to display the stored value in the second edit box. Since it is a multiline edit box, all the values in the first edit box are displayed in the second edit box.
So if the check box is checked, then i should receive the values stored in the temporary variable line by line only.
Can anyone help to do it?

Yes, but what specific piece are you having trouble with? I'm assuming you've tried this on your own but are not quite getting it all to come together.
Do you have OnClick() handlers for the two buttons? Do you have a temporary variable? Are you using GetWindowText() and SetWindowText() properly? Are you getting the state of the checkbox with GetCheck()?
