GetOpenFileName structure member variable is tricky...

I suggest you *wink wink* cough up US$79 - a laughably small price for a great productivity improvement.

Don't you yourself earn your income (or plan to) from the fact that others pay for your efforts?

Here is my problem:

In order to use GetOpenFileName I use a OPENFILENAME structure which has a member variable called lStructSize.
In MSDN I am advised to use sizeof(OPENFILENAME) to initialize this one IF WINDOWS IS WIN2000 OR LATER!!!
otherwise I should use OPENFILENAME_SIZE_VERSION_400.
All is fine. I determine which type of Windows is my app running and use different initializations but this

OPENFILENAME_SIZE_VERSION_400 seems undefined! What can I do?!

TNX! Wink | ;-)

OPENFILENAME_SIZE_VERSION_400 is defined in <commdlg.h>

Call GetVersion[Ex] to determine which version of Windows your application is running on then set the lStructSize field of the OPENFILENAME accordingly.

It doesn't work!
My commdlg.h header file supplied with VC++6 does *not* include this definition at all. In fact no .h file from my distribution doesn't contain it. In a moment of desperation I searched brute-force-style ALL files on the hard drive for this string. None. Except cache files of Opera (web browser and text files that I wrote).
Let's say I might (??!) have an incomplete distribution of this Visual Studio. What if I would nicely ask you if you could tell me the number value of this constant?
It's probably unnecessary to tell you how to do that.

Thank you.

PS: Could it be the fact that I don't really like C ?!? Maybe it has a mind of its own and senses my hate? Smile | :)

I am thinking about purchasing Visual Studio.Net and would like to know if there is a cheaper version of VS.Net since I can't afford an $899 product. I am a student though, I just want to transfer to new technologies... Is there a cheaper way of getting visual studio.net?

MFC questions

Hi,

1. I have put a TabControl inside a formview in the MFC-SDI application. If I resize the window I want the tab control to always fit in the window (that means if I make the window bigger the control inside will become bigger and if I make the window smaller I want the control to get smaller). Please advise how I can do that?
2. How can I make a SDI application non-resizable?

Thanks,

Add a WM_SIZE handler in your view class. In it, do the following:

CRect rectView;
GetClientRect (&rectView);
m_tabCtrl.MoveWindow (&rectView);

This will cause the tab control to fill the view's client area.

I used following code Onsize
but I'm getting asserting error at line 279 of winocc.cpp

CFormView::OnSize(nType, cx, cy);

CRect rectView;
GetClientRect (&rectView);
m_TabCtrl.MoveWindow (&rectView);

Perhaps you haven't linked m_tabCtrl to the tab control in the dialog template? Put this line before the call to MoveWindow():

ASSERT (m_tabCtrl.GetSafeHwnd() != NULL);

to ensure that m_tabCtrl has been properly created before you try to resize it.

It worked. Thanks.... I have another similar question Smile | :)

I have two tree controls attached to the tabs in the tab control. To fit the tree control in the tab control what should I do? 'cause I can't write the wm_size handler for the tabcontrol as I'm adding the tree controls in the formview, not in the tabcontrol class.

I think you might be confusing a CTabCtrl with a CPropertySheet. A CTabCtrl doesn't "contain" child dialogs or controls - all it does is allow the user to select a tab. A tab control's parent receives notifications when the current tab selection changes.

That being said, what you probably want to do (to mimic the behavior of a CPropertySheet) is to create a bunch of child controls/dialogs (whose common parent is your view), one of which is displayed in response to the change in the currently selected tab. You'll also need to check the "Transparent" attribute of the tab control so that it doesn't hide the child controls/dialogs. The appropriate control/dialog is displayed in response to a change in the currently selected tab in the following manner:

// First hide all controls
CWnd* pDisplayedWnd = NULL;
m_treeCtrl_1.ShowWindow (SW_HIDE);
m_treeCtrl_2.ShowWindow (SW_HIDE);

// Next, determine which one should be shown
int nCurTab = m_tabCtrl.GetCurSel();
switch (nCurTab) {
  case 0:
    pDisplayedWnd = &m_treeCtrl_1;
    break;
  case 1:
    pDisplayedWnd = &m_treeCtrl_2;
    break;
  default:
    // Did you forget to support a tab?
    ASSERT (FALSE);
    break;
}
ASSERT (pDisplayedWnd != NULL);

// Display the control
pDisplayedWnd->BringWindowToTop();
pDisplayedWnd->ShowWindow (SW_SHOW);
pDisplayedWnd->Invalidate();
pDisplayedWnd->UpdateWindow();
pDisplayedWnd->BringWindowToTop();
pDisplayedWnd->SetFocus();

If this is too much work, you might want to consider using a CPropertySheet. See the examples at CP if you need help.

Don't forget to call SetScaleToFitSize(cx, cy) at he end of your OnSize() procedure otherwise you will get scroll bars shown if the client rectangle size is smaller than the size of the dialog template used to create the form view from.

I'm using a formview here, setscaletofitsize() is for the scrollview. can you please tell me how I can use it for the scroller in the formview?
