Tried that.
And I tried setting the normal windows styles (in addition to and instead of the extended styles) as well.

That sounds like the non-client area isn't getting calculated or painted properly. When the scrollbars are added, they go in the non-client area and force a recalc/repaint, which also makes the border appear.
Try calling:
tree.SetWindowPos ( NULL, 0, 0, 0, 0, SWP_NOZORDER|SWP_NOMOVE|SWP_NOSIZE|SWP_FRAMECHANGED ); SWP_FRAMECHANGED is the important flag, that will make the control recalc its non-client area.

You, sir, are a god. That did it.
I tried MoveWindow earlier, but neglected to include that flag.

Hi !! I'm programming in MFC. I want a CStatic label control to have font color at red. I don't know how to do it, because I'm using this code:
CFont* my_font = new CFont;
my_font->CreateFont(here all the parameters that I need...);
but I can't see anything for the color... What can I do ?? I think that I've to do something with CDC or something... but please, if you could show an example...
Thanks in advance !!

Yes you have to use CPen pen(..) and then pDC->SelectObject(pen);
don't forget to free resorces DeleteObject(pen)
because after some time our application my behave in funy way

CPen is for line drawing. You need to use CDC::SetTextColor(COLORREF) to choose what colour the text gets drawn in.

Thats because the control's font has nothing to do with the colour being displayed.
One method that I use is to implement the WM_CTLCOLOR message handler, and set the draw colour (SetTextColor()) for all or individual static control.
Or you can use a derived label class like this: CLabel[^].

Does anyone have a tutorial about adding C++ (Visual Studio) code as a macro in Excel. Need to know this for some job interviews. Thanks
|
|
|

That I know of, the macros used in Excel (and all of Office) are VBA (a derivative of VB), not C++.

Do you mean how to create a COM Add-in? Because Excell macros are VBA code, not C++, but if you are referring to Add-ins, your COM class must implement the IDTExtensibility2 interface in order to work with any MS Office program.
Do a search on the MSDN on IDTExtensibility2, also you can take a look to this article, Comaddin.exe Office 2000 COM Add-In Written in Visual C++, it is a Win32 project that you can use as starting point, but I suggest you to use ATL to help yourself with this task.

Hi, I must get a string from a function included into a DLL, imported in a ASP.NET page.
The code:
----
Into a .aspx.cs page:
//def. function included into a DLL
[DllImport("WebUtility.dll", EntryPoint = "getDescr")]
public static extern string getDescr(int id);
//call the function:
string descr=getDescr(123);
---
into the c++ program, the function is definied as:
char* getDescr(int id) {
char* ret=new char[LUNGHEZZA_STRINGA_MEM];
strcpy(ret,oggetto[id].descr);
return (ret);
}
If I throw the application, the server give me the error: System.NullReferenceException: Object reference not set to an instance of an object.
But this error is generated not every time, but random!! some time I can view the string correctly! Why?
Thanks for the help!!!

You can try
[return: MarshalAs(UnmanagedType.LPStr)] However, that's going to be tricky: what frees the string?
If you control both the C# code and the DLL, I'd change your API so it takes a string pointer and a size:
BOOL GetDescr( int id, char* pBuffer, int bufLen )
{
if ( bufLen < LUNGHEZZA_STRINGA_MEM )
{
return FALSE;
}
else
{
strcpy( pBuffer, oggetto[id].descr );
return TRUE;
}
}then call from C# like so:
[DllImport( "WebUtility.dll", EntryPoint=GetDescr )]
public static extern bool UnsafeGetDescr( int id, StringBuilder buffer, int bufLen );
public static extern string GetDescr( int id )
{
StringBuilder sb = new StringBuilder( LUNGHEZZA_STRINGA_MEM );
if ( !UnsafeGetDescr( id, sb, sb.Capacity ) )
{
return null;
}
else
{
return sb.ToString();
}
}
Stability. What an interesting concept. -- Chris Maunder

Hi Friends,
Our product uses shell integration to extend the functionality of the explorer. when doing some internal operation i may get crash. Explorer then dies. Instead of try/catch in each functionality I need a generic solution so that i can do some cleanup at the time of crash.
(i)I tried with Hooking windows messages but i am not getting the quit/destroy message when the explorer crashes abrubtly(Terminate process)
(ii) I tried with some solutions in the internet for monitoring the process but it is complex with additional server / dll that is injected with all process. Also this solution causes performance difference.
Can any one of you please help me to find a simple solution so that i can handle this situation.

Have you tried some low level debuggers like softice or WinDBG?

Thanks for your reply.
Sorry, I dont know the usage of these debuggers.
Can you please explain more details about that.

the vertical scroll bar doesnt get enabled if i add string which doesnt fit a list box. Any ideas what seems to be the problem here. Horizontal scroll bar seems to work fine.
m_lstboxMessages.AddString(sServerMsg);<br />
UpdateData(FALSE);
where m_lstboxMessages is control variable of CListBox
Any suggestion regarding this??

Make sure that the Vertical ScrollBar property of your control is enabled. You should be able to see this in the resource view.

This indicates that the horizontal scroll bar is not working. The vertical scroll bar is not concerned with a string's length. It comes into play when there are more items in the control than can be displayed (e.g., the control can only show 10 strings but 15 have been added).
If I am correct, it sounds like you simply need to call SetHorizontalExtent() in the dialog's OnInitDialog() method..

There is no need to (ever) call UpdataData().

nopes thats not the case the horizontal bar shows correctly...
when i add a long string. It only shows a part of the string according to the vertical height i.e it just shows only the last 10 characters or something like that...

I think I understand, but a picture is worth 1,000 words. Can you provide one?
