CYourDialog dlg; //(CYourDialog is the class where the CTabCtrl is)
CEdit* pEditdlg = (CEDit*)dlg.GetDialogItem(IDC_EDIT); //Is the Control Id in the tabcontrol

CString str = _T("");
dlg.GetWindowText(str); //Ready

Youssef, I'm sorry, I found an error in my answer.

CYourDialog dlg; //(CYourDialog is the class where the CTabCtrl is)
CEdit* pEditdlg = (CEDit*)dlg.GetDialogItem(IDC_EDIT); //Is the Control Id
in the tabcontrol

CString str = _T("");
pEditdlg->GetWindowText(str); //Ready <= This is the corect.

Cheers!!!

Exception Question

12-Jul-01 8:07

I have just started using exceptions, catching both built in types and defined objects. However, as I see it it would be very rare that I actually have a use for doing this. There is always a way around it, usually just error checking. I recall from using java that there are special types defined such as ArrayOutOfBoundsException which you can catch- these types also have relevant methods inluded for diagnosing and working with the exception. Is there no similar concept apart from std::exception...

Thanks in advance.. Smile | :)

Not always. If you have a library that uses throw to report errors, your only solution is to use try and catch. And don't forget about operator new - it throws an exception when there's not enough memory to satisfy the request. Visual C++ is not up to standard in this area (yet) and will simply return NULL. Hopefully, they will fix this in VC 7 (any Beta2 user to comment on that?)

mfc text editor

12-Jul-01 7:49

hello, i really need urgent help with this problem, i look about everywhere but i just can't seem to find an mfc based texteditor program. The problem is this: i have a textbox and i declare a member variable for it as a CString.
Now i have to write the text from this textbox to a file. just like that. i know this really can't be a problem for you guys so please post a quick response here. i can't use getwindowtext and all that because it works with HWND's and u know the mfc stuff is with CWnd.

Thanks
Smile | :)

You have two samples in the MSDN, One is the SUPERPAD, and the other one is MULTIPAD.
If you have not the samples I can send you by e-mail.

Cheers!!!

Using MFC objects in no way prevents you from dropping down to the APIs. Call the GetSafeHwnd() method of any CWnd-derived object to get its window handle.

If you create a MFC App doc/view project with the App Wizard and select CRichEditView as the base class for the view in the final step, you will get a fairly functional text editor - might be all you need!

yeh i know, but its a dialog based app so...

You could use this code to pull your string from the text box and dump it to a file..

CFile fileEditText;
//Write the edit box text to a file
if (fileEditText.Open("text.txt",
	CFile::modeCreate + CFile::modeWrite))
{
		//Write out the full string
		fileEditText.Write((LPCSTR)m_edit,m_edit.GetLength());

		//Close the file
		fileEditText.Close();
}

Hope this helps

I want to dock below the main frame, like so...

 _______________________________
|                               |
|                               |
|          Main Frame           |
|                               |
|_______________________________|
|                               |
|           Dialog              |
|_______________________________|

so that its not a child window being docked, but its docked on the bottom side of the main frame border....

Something like Winamp windows snapped one to another? Make dialog modeless and handle WM_SIZE, WM_SIZING, WM_MOVING and WM_MOVE in frame and dialog. The messages are sent when user moves/sizes the window - in the handler call SetWindowPos to keep other window snapped.

You should be able to you a model dialog also because it get these messages also.

It gets them for sure, but users can't access mainframe when modal dialog is displayed - the main window is disabled.
