Justin Somerville7-Jun-02 3:09 Justin Somerville 7-Jun-02 3:09  I am trying got get the horizontal scroll bar to be displayed on a list box, then the item text is wider than the list box, like the vertical scroll bar. Please can someone help me as I am very . Re: Question on horizontal scroll for list box. Roger Allen7-Jun-02 4:29 Roger Allen 7-Jun-02 4:29  OK, this is a guess/from memory. A list box will be using the in-built scrollbars (which you cant get a ScrollBar* pointer to). You have to access and control them by using the CWnd scrollbar base class functions. You may also need to modify the style opf the list box to have the WS_HSCROLL style set. Then you should be able to use the CWnd functions to control the scrollbar visibility/scroll range etc Roger Allen Sonork 100.10016 If I had a quote, it would be a very good one. Re: Question on horizontal scroll for list box. PJ Arends7-Jun-02 5:25 PJ Arends 7-Jun-02 5:25  Create your list box with the WS_HSCROLL windows style ( Horizontal Scroll check box in the properties->Style page ) and then set the width with the SetHorizontalExtent() function. You can get the width of the text using the GetTextExtent() function. HTH --- CPUA 0x5041 Sonork 100.11743 Chicken Little Within you lies the power for good - Use it! How to get the exitcode of a thread Klaus Petersen7-Jun-02 1:33 Klaus Petersen 7-Jun-02 1:33  Hi I hope someone can tell me how to retrieve the exitcode of a thread the right way. The code below shows how I retrieve the exitcode now. But it doesn't work and i don't understand why. DWORD exitcode = STILL_ACTIVE; //set autodelete to false. This allows us to retrieve a handle for m_pThread. m_pThread->m_bAutoDelete = false; //tell the thread to end m_pThread->PostThreadMessage(WM_STOPTHREAD, 0, 0); //get the exitcode of the thread do { bool temp = ::GetExitCodeThread(m_pThread->m_hThread, &exitcode); Sleep(1); } while (exitcode == STILL_ACTIVE); //when the thread has exited delete the CWinThread object if (m_pThread) { ASSERT(m_pThread); delete m_pThread; } The message handler for WM_STOPTHREAD looks like this OnStopThread() { ::PostQuitMessage(0); } Re: How to get the exitcode of a thread Tomasz Sowinski7-Jun-02 1:29 Tomasz Sowinski 7-Jun-02 1:29  Use WaitForSingle object instead of loop. WaitForSingleObject returns when thread is finished, or specified timeout is reached. Tomasz Sowinski -- http://www.shooltz.com - It's for protection - Protection from what? Zee Germans?

In that case, complete client area is invalidated. Why are you doing this to CDialog? Tomasz Sowinski -- http://www.shooltz.com - It's for protection - Protection from what? Zee Germans?

But to force a repaint, you should do: Invalidate(); UpdateWindow(); /ravi Let's put "civil" back into "civilization" http://www.ravib.com ravib@ravib.com Re: forcing a repaint on a dialog Nish Nishant7-Jun-02 5:39 Nish Nishant 7-Jun-02 5:39  Thanks Ravi It was basically for my demo app in my new article By the way it repainted without the call to UpdateWindow()() on my Win XP prof Maybe if none of the other threads or processes are busy an Invalidate() alone will do, but if the system is real busy, then we can force it by an UpdateWindow() I am correct I hope Nish Author of the romantic comedy Summer Love and Some more Cricket [New Win] Buy it, read it and admire me Re: forcing a repaint on a dialog Ravi Bhavnani7-Jun-02 9:14 Ravi Bhavnani 7-Jun-02 9:14  Yes, UpdateWindow() causes Windows to send a WM_PAINT message to an invalidated window, while Invalidate() cause WM_PAINT to be posted. I use UpdateWindow() to force a repaint when I can't afford to wait for the posted WM_PAINT to eventually arrive. It probably doesn't make a difference in your demo app. /ravi Let's put "civil" back into "civilization" http://www.ravib.com ravib@ravib.com File extension 7-Jun-02 0:51 7-Jun-02 0:51  Hi How can i associate a file extension with my app? i want that all double clicks will will open the files in the same instance of my app. thanks Re: File extension Nish Nishant7-Jun-02 0:53 Nish Nishant 7-Jun-02 0:53  Anonymous wrote: How can i associate a file extension with my app?

In the C++/MFC section, it's called "Avoiding Multiple Instances of an Application". No generalization is 100% true. Not even this one.

Since I don't have the doc-view framework, AddDocTemplate() doesn't work. Thanks!
