Open a MDI childframe without using the menue

Hi,
I have a MDI application with one open childframe.
I want to open a new childframe automaticly. I call OpenDocumentFile(file) and the childframe opens, the correct data will be displayed. When I look on the Document template I can see that for every childframe it exist an doc. But when I want to use the document functions for saving for example then I use only the document of my childframe that exist before I used OpenDocumentFile().

Must I do something to bind the document template to the right childframe?

Thanks for help

Problem with SetClipboardData on Win98 [modified]

I have code written as below :

CString csText;
HANDLE hData=NULL;

m_emailAddress.GetWindowText( csText );

if( (hData=GlobalAlloc( GMEM_MOVEABLE|GMEM_DDESHARE, (csText.GetLength()+1) )) )
{
LPVOID lpLockedMemory=NULL;
lpLockedMemory = GlobalLock( hData );

CopyMemory( lpLockedMemory, csText.GetBuffer(csText.GetLength()), csText.GetLength() );

if( SetClipboardData( CF_TEXT, lpLockedMemory ) == NULL )
{
AfxMessageBox( "Unable to set Clipboard data" );
GlobalUnlock( lpLockedMemory );
lpLockedMemory = NULL;
CloseClipboard();
return;
}
}

Now, this code works fine on Winxp, but for Win98 I get NULL as return value of SetClipboardData(). Can anyone help on this?

Yes, but not in the Lounge. That's why there's a red "No Programming Quesions, Please" sign at the top of the page...

Post in the correct forum and you might just get some assistance with your problem.

What work does this require ? I mean, I have no knowledge of databasis and SQL and so, but is this done easily or do you have to dig somewhere to find the thread and reput it in another table ?

No win98 system , to check this.
Can you use GetLastError to check what error its returning.

Your memory management is a bit off. Call GlobalUnlock() before SetClipboardData(). If SetClipboardData() succeeds, the clipboard owns the memory, so you're done. If it fails, you need to GlobalFree() the memory.

It is not necessary to call GetBuffer() since you are not modifying csText.

sachinbhave wrote:

Which means you should be calling GetLastError() to find out why.

sachinbhave wrote:
GlobalUnlock( lpLockedMemory );

You should be calling this function regardless of whether SetClipboardData() fails or not.

sachinbhave wrote:
CloseClipboard();

There's no reason to call this if SetClipboardData() fails. Nothing is open at that point.

Hi all,

I am creating a Edit Box Dynamically in CDialog Box. And when i Right Click on the Edit Box what i have created i want to show a Menu.

//===========================================================================
//Source for Creating the Edit Box when mouse is clicked.

CEdit *ptr = new CEdit;
ptr->Create(WS_VISIBLE|WS_CHILD|WS_BORDER|WS_TABSTOP|ES_AUTOHSCROLL,CRect(point.x,point.y,point.x +100, point.y +20),this,NULL);

Note : the Last Parameter is the ID for the Edit Control in Create(...) Api.

You need to add the entries of the control in the message map manually. The best way to do it is to look how class wizard does and do the same for your control.
So, add an edit box to your dialog, add the handler with classwizard look at the message maps entries (in the dialog class header file and source file) and see what has changed. Now you can do the same for your control.

Hi Cedric Moonen,

My Doubt is that the CEditBox doesn't Handle the WM_RBUTTON_DOWN Event. The Events handled for the Edit Box are.

EN_CHANGE,EN_ERRORSPACE,EN_HSCROLL,EN_KILLFOCUS,EN_MAXTEXT,EN_SETFOCUS,EN_UPDATE.

What about the Event Handler of WM_RBUTTON_WOWN Event.

please tell me your suggestions.

These aren't events handled by the edit control. These are notifications posted by the edit control to it's parent. In that case you can use WM_PARENTNOTIFY[^]. Or if your only interested in a right-click there is NM_RCLICK[^] notifications.

23-Aug-06 20:46

Hi all,

I have created a device independent driver. For which i want a application launcher. My drivers name is "TestIOCTL" and its symbollic link is "\Device\TestIOCTL ". I now want to open this driver file for which i have used the following code segment.

hDevice = CreateFile ("\\DosDevices\\TestIOCTL",
0,
FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL,
OPEN_EXISTING,
FILE_ATTRIBUTE_NORMAL,
NULL
);

The hDevice returns 3 thro GetError() Method meaning File not found. Can anyone tell me how to open this driver file.

Thanks In advance.
Regards
Kenny.

Correction:
Error 3 means ERROR_PATH_NOT_FOUND
(Error 2 means ERROR_FILE_NOT_FOUND)

Just a hint, I never opened a driver myself.
But I suggest you try these for the "file" name:

L"\\\\.\\Device\\TestIOCTL"
L"\\\\.\\TestIOCTL"
L"\\\\.\\DosDevices\\TestIOCTL
