splitting the window - C / C++ / MFC Discussion Boards

Edit->Find and Replace->Replace in Files

Check out the regular expression you pretty much can do anything old grep used to do.

Nope, you gotta do it the old fashioned way. Find/Replace.

My guess why DevStudio doesn't have this feature is that it may be difficult to do accurately every time. They'd rather avoid the risk of renaming something inappropriately.

Hello,

I would like to make something similar to the Start menu of 2000/XP: you can double click on any popup menu to open the item (therefore you can select items that are not leaves in your menu). Anyone has an idea how to do this?

Hi!

I'm doing this:

if(bRectangleFlag)
{
if (bAddTenHousesFlag = true)
{
CBrush myBrush;
myBrush.CreateSolidBrush(RGB(255,0,0));
HBRUSH hMyBrush = (HBRUSH)myBrush;
pDC->SelectObject(hMyBrush);
pDC->Rectangle(Anchor.x,Anchor.y,DrawTo.x,DrawTo.y);
pDoc->pMetaFileDC->SelectObject(hMyBrush);
pDoc->pMetaFileDC->Rectangle(Anchor.x,Anchor.y,DrawTo.x,DrawTo.y);
}
pDC->SelectStockObject(NULL_BRUSH);
pDC->Rectangle(Anchor.x,Anchor.y,DrawTo.x,DrawTo.y);
pDoc->pMetaFileDC->SelectStockObject(NULL_BRUSH);
pDoc->pMetaFileDC->Rectangle(Anchor.x,Anchor.y,DrawTo.x,DrawTo.y);

}

But the return from SelectObject is killing mu program!

Anyone know why?

Thanks,

pDC->SelectObject(&myBrush);

You don't need hMyBrush.

Many thanks, it now works !

Try something like this:

[...]
{
CBrush myBrush;
myBrush.CreateSolidBrush(RGB(255,0,0));
CBrush* pOldBrush pDC->SelectObject(&myBrush);
pDC->...
...
pDC->SelectObject(pOldBrush);
}
[...].

This way, you are sure to select the brush out of the DC (by selecting in whatever has been there before) before the variable that contains it goes out of scope.
Hope this helps

Hi Friends

I created an MFC Application using AppWizard with the option "Split Window"(something like this) in the 4th step's advanced section. It splits the window dynamically.

Can I make this dynamic splitting static ??
by calling 'CreateStatic' instead of 'Create' in CFrameWnd::OnCreateClient
i.e

BOOL CmyMain::OnCreateClient( 'parameters' )
{
// creating splitter
m_wndSplitter.CreateStatic(this,
1 // one row
2 // two columns
)
return TRUE;
}

Will it solve my problem or i need the other stuffs ??
If YES the please identify them also

BTW Do I need to create view for each splitted window ??

you can reply me at aatifaqeel@yahoo.com

Thanx for helping me

Hy people!
My CRichEditCtrl is taking me out of control... I don't know what to do...
It haves an CString variable and a control variable associate. When I type more than 256 chars, it just crash... Frown | :(

If someone have some idea...
thanks all for the attention.
cheers!

Ricky

I just tested this with a RichEditCtrl using a control and text variable mapped to it using the DDX_COntrol and DDX_Text functions, and couldn't reproduce the problem. Are you doing anything special in the EN_CHANGE handler or anything else?

Could you also run in debug mode and get the line of the crash and a stack trace, as that may help pinpoint the problem.

Yes Roger, I found the problem...
I'm using SendMessage(EM_SETEVENTMASK, (WPARAM)NULL, (LPARAM)ENM_UPDATE), just to count the number of chars.
The problem was in the CString variables that was associate with the control. I delete them, and used GetWindowText instead of UpdateData(); and works fine.
Thanks for your help! Smile | :)

cheers!

Can I use CPaintDC outside OnDraw() and other related functions ? And if so, how ?

This is because I have a big problem: When I draw objects using CClientDC they appear on a screen location (inside the client's area) different from when I use CPaintDC, in the OnDraw() routine because of the Invalidate() message....
What is going on ?

Thank you Smile | :)

In CView::OnDraw you don't need CPaintDC and CClientDC. You have CDC* parameter:

void CMyView::OnDraw(CDC* pDC)
{
pDC->...
}

Yes, I know. I explainied my problem wrong:

I call the OnDraw() routine when I need to repaint the client area. But when I need a device context in other routines, like OnMouseMove(), I create a CClientDC device context. The problem arouses when I move the ViewPort. I don not know why, but the CPaintDC device context already knows this, whereas the CClientDC does not.

So, whenever I scroll and then draw something with the mouse I get the objects I drew in a position. But when I redraw the whole client area the objects change position....

Thank you

The general approach is drawing only in one place - OnDraw (or OnPaint, if class is not CView). Drawing from any other places is overwritten by OnDraw, in any case. In mouse message handler you make the changes in drawing objects (for example, change some variables in CDocument) and invalidate the view or part of it.

I agree with you, but in this case I need to draw outside the OnDraw() or OnPaint(), although I a have a CView class. I solved the problem by writing a clone of OnPrepareDC for a CClientDC device context type, and use before I use the CClientDC class. Big Grin | :-D

By the way, how does one do to invalidade only part of the client area OMG | :OMG:

?

Thank you for your time and patience

InvalidateRect ?

BOOL InvalidateRect(
HWND hWnd, // handle to window
CONST RECT* lpRect, // rectangle coordinates
BOOL bErase // erase state
);

It was always there.

Yes it was Big Grin | :-D

!!! Thanks

I have a CHeaderCtrl with icons in some of the columns. When I resize the columns and make it smaller the divider partly overwrites the icon. It appears to be 6 extra blank pixels on each side of the divider. Is it possible to make that smaller.

Thanks for help
