Very sorry for waisting your time Unsure | :~

I figured it out

void main(int argc, char* flag[])
{
// acrgc = number of string param
// flag[1] = first string param
// ...
// flag[n] = n string param
}

Thanks for your time though

how can i update the dialogs of my dialog application in my own class. Currently i've inherited from the *Dlg class, and even though the compiler returns no errors, i get a error for the command UpDateData(TRUE) while the program is running, saying Debug Assertion Failed.

Anyone know what the problem is?

Probably something wrong in the DDX variable mapping declared in ::DoDataExchange(CDataExchange* pDX).
Be sure to use the Dialog classwizard to add or modify those members. Also check if member types are adequate (MSDN MFC Technical Note can help for that).

Let's swallow a small raisin.

Will you be able to post your code ?? I think it's likely that the data that you're trying to use is no longer exist. This happens when you don't overide the OK button!!

I'm writing to a database using appendChunk. it just goes and keeps adding to the same database - instead of overwriting it. THere dont seem to be any parameters that I can set in the method. I open the database using the recordset.Open function and I didnt see anything there that I could set either to make the database get rewritten.

PLease help!

How to maximize child windows

Ancient Dragon17-Aug-02 15:53

17-Aug-02 15:53

I have an MFC MDI program using VC6. When the application starts I want the initial child window to be maximized within the frame. I've tried ModifyStyle(0,WS_MAXIMIZE); in the OnActivateView() and added cs.style |= WS_MAXIMIZE; to the beginning of PreCreateWindow(); Any other ideas?

I don't know if this is the correct way, but in the ActivateFrame Method I set the SW_SHOMAXIMIZED flag, this does the job just for the intial activation of the window.

<br />
void CChildFrame::ActivateFrame(int nCmdShow)<br />
{<br />
	// TODO: Modify this function to change how the frame is activated.<br />
	nCmdShow = SW_SHOWMAXIMIZED;<br />
	CMDIChildWnd::ActivateFrame(nCmdShow);<br />
}<br />

If you have more than one window in your MDI, i have noticed it will unmaximize when you switch to a new window.. I tried to get around this by using a ModifyStyle(NULL,WS_MAXIMIZE)

<br />
void CChildFrame::OnSetFocus(CWnd* pOldWnd) <br />
{<br />
	CMDIChildWnd::OnSetFocus(pOldWnd);<br />
	<br />
	// TODO: Add your message handler code here<br />
	ModifyStyle(NULL,WS_MAXIMIZE);<br />
}<br />

As I said, I don't know if this is the correct way to do it.. Its just what I figured out while I was playing.. Please let me know if you find a better way.

Thank you for your help. ActivateFrame() alone works in my program without the problem you described. My view is derived from CHtmlView, which is derived from CFormView. I created two instances of the same view during runtime (that is, I selected File | New), switched between them (Window | <view number="">) and both windows stayed maximized.

CChildFrame::ActivateFrame() is a recomended way to do this. I don't know if your code in CChildFrame::OnSetFocus() will do anything usefull however.

With MDI only one window is ever maximized at a time. When you switch to another window, the current window is restored to its normal size and then the new window is maximized. This is all a pain in the backside as far as I'm concerned and I assume it has something to do with the early Win 3.x MDI implementation.

One of the problems with this is that you can see the windows flash to restored and then maximized size as you change MDI windows and open and close windows. This flashing varies across different windows versions.

In my CChildFrame::ActivateFrame() in ED for Windows (see sig) I wrap the call to CMDIChildWnd::ActivateFrame() in pMDIClient->SetRedraw( FALSE/TRUE ) calls.

Hi, I'm a newbie to MFC.
I have an MDI with CFormView as my base class. I can't find the ActivateFrame() function.

Someone suggested I try this in CMyFormView::OnInitialUpdate()
CFormView::OnInitialUpdate();
GetParentFrame()->RecalcLayout();
ResizeParentToFit(FALSE);

but this still doesn't work.

Any suggestions?

Cheers

ActivateFrame() is a member of CMDIChildWnd. The Help will tell you this. Wink | ;-)

To access it you need to derive a class from CMDIChildWnd. This is usually named CChildFrame.

Then you can use CChildFrame::ActivateFrame()

If you want to get at the MDI Client Window inside this then use: CWnd* pMDIClient = GetParent();

Make sure you call CMDIChildWnd::ActivateFrame() from within your CChildFrame::ActivateFrame().

I've used it in PreCreateWindow in the ChildFrm and it works great. cs.style |= WS_MAXIMIZE. I placed it after the CMDIChildWnd::PreCreateWindow( cs ); Perhaps something else is confusing it.
