Use ModifyStyle(WS_OVERLAPPEDWINDOW,0) in OnCreate of your function, instead of this.

send message WM_CLOSE for close button. and minimizing you need to use ShowWindow().

If you have use WS_OVERLAPPEDWINDOW style, there will be no menu.

this doesn't mean anything. you have to know what is stored in this file, if it is binary or text file first. if it is binary, you have to know what is structure of the datas.
what application does generate such .dxf files ?

I think it depends to AutoCad

Hi,
On a toolbar I am working on, the button is erased but it still responds to mouse clicks. I have already tried NOT to ANSWER the WM_ERASEBKGND; use BeginPaint-EndPaint, or GetDC-ReleaseDC instead, but the background is either erased or it is completely transparent and not drawn. Either way, the button does not show, but is active. Now, if I don't respond to WM_PAINT messages, the toolbar is correctly drawn, and the button is ok...
Do you know what I should do?
ThanX

What is it exactly that you're trying to do?

I am just trying to change the bkgnd/text color of a static control, created during OnCreate(). To do this, when the browser is resized and Windows sends a WM_PAINT message, I wrote the OnPaint()->BeginPaint() to change it. Exactly: There is a main toolbar which holds a static control and a button. The OnPaint() is inside the .cpp of the main toolbar. Inside the OnPaint() I try to paint the main toolbar and the static control. The static control gets painted ok, and so does the main toolbar. However, the button disappears even if I don't paint anything like:
LRESULT CMFToolbar::OnPaint(UINT uMsg,WPARAM wParam, LPARAM lParam, BOOL& bHandled)
{
return 0;
}
->Result: Everything is in place, except for the button that disappears.
In sumary, what I need to do is this:
-> Create a static control to receive scrolling text feed;
-> Change the color of this text and the control's bkgnd;
-> Put an image on the toolbar;
-> Create a button that DOESN'T DISSAPEAR 
Sorry if I can't explain very well, but I am more used to C programming, so talking about classes and how they are called, when there is no main function is a bit confusing for me
For instance, I do not understand very well the following piece of code:
<br />
HBRUSH CMyDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)<br />
{<br />
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);<br />
<br />
if (pWnd->GetDlgCtrlID() == IDC_MYSTATIC)<br />
{<br />
pDC->SetTextColor(RGB(255, 0, 0));<br />
pDC->SetBkMode(TRANSPARENT);<br />
hbr = GetStockObject( NULL_BRUSH );<br />
}<br />
<br />
return hbr;<br />
}<br />
-> What is CMyDlg? Is it the main toolbar?
-> Where do I put this kind of code?
-> Where is the BRUSH returned to?
Oh Well...
Sorry...
Thanks

What are you trying to do in WM_PAINT ?
Whatever area you paint you should validate, then let the default handler paint the rest.

Ok, here's what I need to do:
|----- Edit Control (Child Window)
|
Main_Toolbar---- ----- Button
|
|------ Static Control (Child Window)
-> Create a toolbar with an edit box, for user input; (OK)
-> Create a button that responds to mouse click; (OK)
-> Create a static control with text; (ok)
-> Create a bitmap on the toolbar; (not ok yet, but i have not worked on it yet)
Now, how am I trying to do these:
-> Create everything inside the OnCreate(); (ok)
-> Position everything inside the OnSize(); (ok)
-> Change Static Control's Text/Bkgnd color inside OnPaint(); (NOT OK)

<br />
<br />
After the WM_PAINT message, even if I don't paint anything inside the OnPaint(), the button disappeas...
Some answers to other posts I had posted people said that I shouldn't call BeginPaint()-EndPaint() of the child window (m_ReadRssWnd) inside the OnPaint() of the main toolbar (m_hWnd).
I don't understand this... isn't there just one OnPaint() method?
Thanks in advance

You need to read up on how messages are handled/pumped/routed, WM_PAINT, Begin/EndPaint, Rebar controls, and OnCtrlColor.
I'm afraid the MSDN docs for all are too lengthy to replicate here.
In short, i think you may be making things harder than they need to be.
Try using a rebar and handle OnCtrlColor in the parent control.

hey all,
iam trying to do the following.
the data gets stored in a group of files. the files have to be called back or opened at a later stage to plot.
on selecting a checkbox, the default or the first file name (of say, 4 files) should be displayed in an edit bar. the edit bar goes active only on clicking the check box. the edit bar should be able to scroll through to find all the available files. the files are stored with .txt extension.
the file that gets selected gets plotted which is done by clicking another pushbutton "plot".
I cannot get the file names to be displayed in the edit bar. how do i do it?
Thanks in advance.

I didn't understood what was your problem exactly. If you don't know how to search for the files (and find the appropriates one), take a look at CFileFind[^] class.

thathvamsi is it possible to say your problem i cant understand your problem is plot or files or get files or datas in files?

Hi Guys,
Need a clarification...
I have an MFC Server/Client multithreaded Application, now i'm looking to rewrite in C#.Net. It uses Oracle 9i as database. Before i jump to my development work, i need to clarify if it is a right move to write in .net when it comes to performance (server), ease of development, etc.
Could any one please suggest an idea?
Thanks
Rove

MFC is not managed, C# is...
choose your performance side.

If someone agrees to pay enough money and is enough patient, then no problem, go ahead!
Else, my sincere advice is to let it as it is.

.Net is new technology, better you switch over to it or become extinct
