Do you need to WM_CHAR or WM_KEYDOWN or WM_KEYUP?
|
|
|
|
|
print means what ??
Do you want to show char on dialog box??
If yes you can take dialog DC and use function Textout()/DrawText()
|

You don't like text boxes, do you?

Hi Pallini,
Can you see your votes on your profile or its my problem?
|
|
|
|

Nope. I cannot see the votes of my replies. I don't know if it is a new CP feature (at first sight format has changed too) or is a temporary flaw.

It's a temporaly flaw, the reason here [^]

I m opening the image in OnFileOpen() but when i scroll vertically or horizontally it disappears. When done from OnDraw it is doing fine.Please Help.
|
|
|
|
|
when you will scroll the window it will be repainted always.
if you want the the image to be displayed all time you have to handle in OrDraw/OnPaint only.
|
|

I dont understand,can you more explain?

When the it is done in OnDraw function it is displaying image while scrolling. Please Help.

First you need handler methods for scrolling, which update the scrolled coordinates (usually the upper-left corner's coordinates). In these methods add: Invalidate ();
The Invalidate () method will cause OnDraw () to be invoked. Your OnDraw () method should draw the image, starting at the current scrolled coordinates.
An alternative is to use the CScrollView class, which handles scrolling for you. If you do this, the OnDraw () method should just draw the whole image.

How to change the name of MFC single document application
from Untitled to desired one?
|
|
|
|
|
If you wish to change the window title you can simply use SetWindowText.
if you just want get rid of "untitled" then you have to change in initinstance to say cmdNothing explictly.
|
|
|
|
|
Thanks SetWindowText working fine...
|
|
|
|
|
In CMainFrame::PreCreateWindow add this.
cs.style &= ~FWS_ADDTOTITLE ;
This would remove the "untitled" string form the title and then you can use SetWindowText to show what you want.
Somethings seem HARD to do, until we know how to do them.

Hi,
I have an application very similar to the MTMDI sample from MSDN but instead
of deriving CBounceWnd from CWnd and drawing a flying ball I derived it
from CDialog and placed there some controls (CButton and CEdit).
So I have a window running in a separate thread with a parent window in the
main thread.
But on moving/resizing the CBounceWnd is not painted correctly. It has areas
which are not repainted.
We have a workaround for solving a problem with painting in 2 UI threads and
I would be VERY glad if you have any ideas about risks of implementing it.
Say, CSeparateThreadWnd is a CWnd that runs in a separate thread and has a
parent in the main thread. And we do the following:
BOOL CSeparateThreadWnd::PreTranslateMessage(MSG* pMsg)
{
return m_pParentWnd->SendMessage(ID_SOMETHING, reinterpret_cast<wparam>(pMsg), 0);
}
LRESULT CParentWnd::OnID_SOMETHING(WPARAM i_wParam, LPARAM)
{
return AfxPreTranslateMessage(reinterpret_cast<msg*>(i_wParam));
}
</msg*></wparam>
I suppose it's related to the fact that MFC has two different
Permanent HWND<->CWnd maps for 2 threads and when PreTranslateMessage()
is executed in the second thread it reverses by a tree child-parent and
when finds a parent from the first thread assumes that CWnd is NULL and
aborts further traversing.
So we manually throw a message to the main thread to handle all parent
windows operations that were not done.
Is it acceptable?
Is there another solution for the task of placing a child window in a
separate thread?
Thanks a lot!
