Hi,
Thanks for the response.
In the tutorial, this works:
CString strTitle;
int nIndex;
nIndex = GetDlgItemText(IDC_TITLE, strTitle);
The function you posted, GetWindowText() seems to be of the same form as GetDlgItemText() in that it completely ignores the value of the control, m_nTitle, that we already have.
I wondered what was the point of creating a variable to hold the value of the combo box control, if it wasn't going to be used. In turn, I wondered if there is a way to get the text from a combo box using the value of the control.

I spent several minutes reading your sig and wondering what the heck you were trying to tell me before I noticed the line with the method.
Thanks for taking the time to help a beginner.

is there an ASM instruction (or opcode) that normalizes a double value (i.e. adjusts the exponent so the mantissa is .1xxxxx)
(And - if you don't mind - MSVC C++ inline assembly to normalize a double d)
we are here to help each other get through this thing, whatever it is Vonnegut jr.

The real numbers are always stored in normalized form. The high-order bit of the mantissa is always 1 and it is not stored in the real*4 and real*8 formats.
More info: MSDN Library Visual Studio 6.0 - "IEEE Floating-Point Representation and Microsoft Languages".

I have my dll injected into another process. Is there a way from that dll that I can tell what other dll's are mapped into the process, and be able to get the module handle to one of them? Any help is appreciated.

EnumProcessModules() will do that for you. MSDN has a page called "Enumerating All Modules For a Process" that should have you the code you need.

Hi dudes,
I want to change the default background color of SDI client are to black color. Actually it is in white color now. I mean I want to change the background color of View. In dialog box we have WM_CTLCOLOR. But I don't know what to do in view.
Thanks in advance for helping.
Promise.

This is one of the features I plan to add to FooButton[^]. Will let you know when the article is updated.
Meanwhile, you might want to check out (pun intended) some of the other owner drawn buttons here[^].

Hi,
I'm a beginner but I tried to figure it out for you. The following code doesn't work, but it's what I came up with, and maybe it will give you some ideas. I have a simple dialog box with a few controls and I added this function to the Dialog class(CCodeProject_Dialog2Dlg):
HBRUSH CCodeProject_Dialog2Dlg::OnCtlColor(CDC *pDC, CWnd *pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
if(pWnd->GetDlgCtrlID() == IDC_WIN98)
{
pDC->SetTextColor(RGB(255,0,0));
pDC->SetBkMode(TRANSPARENT);
}
return hbr;
}
How did you set the background color?
I can't believe the previous poster wouldn't help you. I clicked on the link he posted, and any of the author's of those button programs should be able to tell you how to do that.
Also, what's up with a programming forum that doesn't allow you to post indented code?

My program has a debug assertion failure and it appears when i close the program the ASEERT failue dialog box is diplayed for a fraction of a second and disappears i am begining to sespect that this is due to the thread i create in my CView constructor in the thread there is an infinte loop and it never exits it postmessages in each second i never worked with THreads is it because the thread associated function never returns a value that i am receving the debug asserion failure ???

Run the program under the VC++ Debugger and when the ASSERT occures press Retry to go into the debugger. Then look at the Stack Backtrace to find the cause.
Threads should be closed properly by your code. There are several waits to do this. One is to wait on an Event that you signal when your app is closing. Another is to force the thread to raise an exception. See: http://www.codeproject.com/threads/threadlibrary.asp [^] for a good example of this.
I have to wonder why your thread is posting a message once a second and what the thread is being used for. Threads shouldn't be an infinite loop. They should either Wait or Exit when processing is complete.

First I wanted to make a thread to post a message each second because i was not satisfied with windows timer WM_TIMER messages i wanted to make a timer that is more or less accurate and won't be affected by other messages placed in the queue such as fast mouse cliks or so.

The main problem is the Dialog box saying i have a debug assertion failure is displayed for a very short time and boom!!! it goes. i could not even see what the error message. let alone to push the button retry, i tired to capture the screen when the dialog box is displayed and it was to fast to do so by pressing the print screen key on the key board.
The debug assertion is caused when i close the window and especially for the first time i boot my comupter and run it from the VC++ editor, after the first build it occurs occasionaly

This makes little sense to me. If your thread is using PostMessage() then you have no better gaurantee of the timer message being received at a specific time than WM_TIMER messages.

I would say you have a serious problem somewhere (not helpfull I know). I'd set a breakpoint in the debugger in the MFC ASSERT code that opens the message box. I'd also have a close look at the thread function. Maybe it is Posting to a Window that no longer exists. Multithreading is a complex area and should be avoided unless you have a very good understanding of how it all works.

Yeap u are right i added a sleep function in the destructor of CView and was able to see the "ASSERT falure dialog box" and saw the file and line number with the assertion failure it seems that the CWnd::PostMessage() first checks to see if the CWnd is valid and hey it fails there.
Thanks a lot (now i have added a volatile bool variable to exit loop and a check to see if the CWnd is valid before posting a message and if not to exit loop)
