Perhaps you're overriding OnShowWindow(), causing the default behavior (that would eventually cause OnPaint() to be called) to not occur? Try overriding OnShowWindow() in the following manner:

CMyDialog::OnShowWindow (BOOL bShow, UINT nStatus)
{
  // Do default operation
  CWnd::OnShowWindow (bShow, nStatus);

  // Force window repaint
  Invalidate();
  UpdateWindow();
}

Thanks for your answer Ravi!
In fact I had already tried that, unsuccesfully...
I don't know exactly when this function is called, but I thought it is only when the application is opened for the first time... no??

Thanks again

Actually, WM_SHOWWINDOW is sent whenever the window is shown, hidden, minimized, maximized or restored, not only at startup. But you're right - what I should have said is, add these lines to your OnPaint() handler:

CMyDialog::OnPaint (...)
{
  m_myPicStaticCtrl.Invalidate();
  m_myPicStaticCtrl.UpdateWindow();
}

This should force an immediate repaint of the static control. If this doesn't work, I'd put TRACE() statements in your static control's OnPaint() handler to see if it's doing anything funky. It might be getting called, but not painting after the first invocation.

Hi,
Did you tried the RedrawWindow() of your CStatic control in your OnPaint()?

Regards,
Eli

Hi Eli,

I had also already tried the RedrawWindow(), but unsuccesfully...
Are threads use for that kind of things??
If you have any other ideas... don't hesitate!

Thanks a lot for your answer!

http://www.nongnu.org/chmspec/latest/Internal.html[^]

Actually I believe, as you are S/W developer you should know the internals working of app that why I am providing you with documentation only.

Anyway, if still need Source code for your problem. I can provide you that too.

You can decompile the CHM file to a set of files in the CHM file.

I use PowerCHM to decompile and compile it.

I am getting an error message, tried hard to come out of this. anybody can help????????????????????
Please Treat it as urgent

sysInfo :- is a class which is calling 'getIPAddress()' which is of type 'std::string'
in sysInfo class the result is returned in the form of std::string,
this is being called in main() function.
os.m_IP_Address = sysInfo.getIPAddress();'
'os' is a object of class which inherits the Recordset class and
'm_IP_Address' is of type CString which is the column name in which the value of "sysInfo.getIPAddress()" should be placed
(os.m_IP_Address = sysInfo.getIPAddress();)
But ,I get the error message as shown below.

error C2679: binary '=' : no operator defined which takes a right-hand operand of type 'class std::basic_string<char,struct std::char_traits<char="">,class std::allocator<char> >' (or there is no acceptable conversion)

I doubt Borland C++ has such a class.

It's been almost 15 years since I've used a Borland compiler, but can you do something like:

SetWindowLong(hwndEdit, GWL_STYLE, GetWindowLong() | ES_CENTER);

Sounds like a job for the sheet's SetActivePage() method.

SetActive() is for select page among the set of pagess.but my requirement is delete the page and addpage into property sheet from another view dynamically.

Then use RemovePage() and AddPage() respectively.

Yes i used but i couldn't delete or add.since i couldn't get the handle of property sheet from my treeview.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
