Should I be doing something more along the lines of what you did, using mouse coordinates like a map, swapping different versions of the entire bitmap into place for the rollover state of each of the 8 arrows?
That's the question that .dan.g. asked. I'm sure it's possible, but not being a full-fledged GUI person, I'm not sure how to go about it.

Search for namespace extensions. It's a shell thing.

Hi all I using MSComm to send ASCII characters to a robot. The robot uses 7 bit ASCII and a char is 8 bit. I have set up MSComm to transmit 7 bit ASCII. Which bit is dropped when MSComm converts from 8 to 7 bits?
Thank you

I'm not sure exactly what you are after, so let me start here. If you know the account name and want the SID, use LookupAccountName(). if you know the SID and want the account name, use LookupAccountSid(). Am I way off?

VS.Net 2003/Visual C++.Net
MFC
Windows 2000
I have a CTreeCtrl in a dialog box (created programmatically, not from a resource). Even though I specify the WS_EX_CLIENTEDGE extended style, the tree control is inially displayed without a border, and without any kind of 3D appearance.
HOWEVER...
If I expand the tree items to the point that either a horizontal or vertical scrollbar is displayed, the 3D appearnce magically appears, and does not go away as long as the property sheet is displayed.
Anyone got any hints?

What if you force the control to repaint?

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
