I hid my edit box by ShowWindow (.., SW_HIDE), and then made it visible by ShowWindow (.., SW_SHOW) and
as a result, the caret is missing. The window has a focus because I can write in it, I can make selections and so on.
The only thing that bothers me, is that the caret is missing.
I had tried ShowCaret (), SetFocus (), it doesn't work.
Can you help ?

I made a test and it works ok. Could you give some more details?

I use straight WinAPI, but anyway thanks for interest, I have figured it out just a moment ago.
The solution is:
1. take the focus from an edit box, make it hidden
2. give the focus to the edit box again and make it visible
And the caret is here. Obviously, the caret is created and destroyed when the window gets and loses the keyboard focus.

Are you using BeginPaint anywhere in your program, DId you make sure to call EndPaint.

I use:
m_dw=_beginthread(ThP, 0, NULL); // successfuly
// ...
PostThreadMessage(m_dw, WM_APP+10, 0, 0); // unhappy
in a dialog-based MFC application.
The thread function is:
void ThP(PVOID pv)
{
MSG msg;
while (GetMessage(&msg, NULL, 0, 0))
{
AfxMessageBox("676767");
}
}
This doesn't work. Have any idea why?

_beginthread returns the thread handle, whereas PostThreadMessage requires the thread ID. Use CreateThread instead to create the thread, as it provides both.

Hello,
I would like to program a kind of dialog screen containing a sort of header (with input area, text fields, buttons, radio buttons, ...) and, under this header, a zone where other dialogs can be displayed (one by one), these dialogs being selected with a tab bar .
To give an example of what I would like to do ... have a look at the dialog "System properties" or "Display Properties" of Windows.
Instead of having buttons on bottom of screen, I would have a header with various controls above this tab bar.
How can I do this kind of stuff in VC++ ?
Thanks in advance

Hi ! I´d like to change the mouse cursor of my app (MFC-Dialog). I looked in the Code Project FAQ, where it is written Put a SetCursor when handling the WM_SETCURSOR message.
So I tried this :
<br />
BOOL CTestDlg::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message) <br />
{<br />
HCURSOR Hcur=(HCURSOR)LoadCursor(AfxGetResourceHandle(),MAKEINTRESOURCE(IDC_CURSOR1));<br />
SetCursor(Hcur); <br />
return CDialog::OnSetCursor(pWnd, nHitTest, message);<br />
}<br />
but this does not work ... what´s wrong ? BTW, is it the best way to do it ?
Thanks

Unfortunately, brute-force solutions tend to be slow
even when performed by modern-day microcomputers,
which are capable of several MIPS except when I'm late
for an appointment and want to finish a compile and
run just one more test before I leave, in which case
the crystal in my computer is apparently designed to
automatically revert to 1 Hz.

In this example, the given code is only for preshaped windows cursor. But the trick is the same : just comment out the return CDialog::OnSetCursor... (that is, the call to the base class) and it works.
Thank you very much Nish (as always..)

You're must write
return TRUE;
instead
return CDialog::OnSetCursor(pWnd, nHitTest, message);

Why not go straight to the source if you wanna burn money? Fraunhofer (sp?) or Thompson would probably be more than happy to rip you off.
Xing might also have something.

Hi,
I'm working with a MemDC and was wondering what is the easiest way to apply a watermark ?
I was going to create a second memDC which I simple write the text to for the watermark the check each bit and use that to add or subtract a small amount from the original memdc to get a watermark effect ?
Are there easier ways ? I need it to work under w95 -> w2000
Thanks..

If you want this to work across all Win32 platforms, you'll need to perform the alpha-blending yourself. Just don't use SetPixel/GetPixel unless your bitmap is very small - performance will be abysmal. You should create DIBsections and access data without GDI.

How do I copy the data from the dc into the DIBsection and then back to the dc when done ?
I looked at DIBSectionLite and it seems to only dealy with using a bitmap as the source and not a dc.
Is it possible to directly draw fonts on the DIB or do I need to draw the text on a dc then copy it to the DIB ?
Are there an examples of this out there ?
Thanks

What do you mean by "open" ? Do you want to launch it from within your application, or to open it in order to read some data ?

Call ShellExecute on the doc type. If it has a program associated with it, it'll be opened in that program.

MS Excel can be automated using COM and be made to do lots of things. If you want to control MS Exccel a lot, good idea would be to use COM. How much control do you want?
