Hi,
I am developing a dialog based application in MFC. In my application i have a multiline edit box. For that i have added scrollbars. Scrollbars are working in WindowsXP. But if i run my application in WindowsVISTA scrollbars are not appearing for the edit box. Can any one tell me where it is going wrong? Smile | :)

Making a static labrary (to use <...> insted of "...")

Hi
I've downloaded free Interbase library - IBPP.
What I must do to use it as <ibpp.h> instead of "..\ibpp\ibpp.h" in my project?
Do I have to move IBPP files from my project folder to ... ?

P.S. I'm new to the C++ scene so if you can write more details of how to do this in MSVS 2005 or DevC++.

Thank you in advance,
Ani

I didn't fully understand what you were asking but I guess that you want to avoid specifying the full path to the include files in your sources, is that right ? If, yes, you have to specify this in the "additional include directories" option. For VC2005, open the project settings -> "C/C++" -> "General" -> "Additional Include Directories". There add the path to the include dir of the library.

Well basically in my code I want to write:

#include '<ibpp.h'>

(I use ' just beacuse of the tags)
instead of

"..\IBPP\ibpp.h"

I know that I have to use static library, but I have no clue about them Smile | :)

Well, and what is the problem with the solution I gave you ? Confused | :confused:

And why do you want to use <> instead of "" ?

no, don't !

<> is meant for the compiler that the include is to be searched from the includes in its installation folder.

this is a C/C++ standard language feature and it is not what you want.

what you want is to reduce the path in the include instruction, don't you ?
well, if you include in the project settings the path to the folder containing the ibpp.h header file, you will then be able to do the following:

#include "ibpp.h"

so, not using <>, but you reduced the relative path included.

do that satisfy you now ?

Personally I don't care if it going to be <...> or "...".

However, I have to change some things in a project written by someone else and ... I can't compile it ... for now. I hoped that if I try to stay as close to the environment that the other guy had, I will compile it.
The program was written in DevC++ 4.0 ... no project, just a make file (can't compile trough it).
I receive: [Linker error] undefined reference to IBPP::CheckVersion(unsigned int)
and so on for all functions inside.

So, this is the main reason for my question ... and I hoped around it to learn more about static library.

Hi All,

Can anyone please tell me whether may I debug a microsoft function like strcpy or IStoreNameSpace: RegisterNotification() or any othe MS functtion?

Thanks!

If the source is available, you can set a break point and step into the source. If the source is unavailable, then you cannot do it.

What does it have to do with if it is a function written by MS or not? Confused | :confused:

why ? your application is crashing in there ?

here is a better advice : fix you code. strcpy() is certainly not the cause.

so, please show your code...

Actually strcpy() is just an example but I am facing a problem with another function, in Windows Mail plugin, it's a COM DLL written in 'c' language, and IStoreNameSpace: RegisterNotification() method fails there....and the last return code which I get is not implemented.

In some cases is the sourcecode available. But you need a complete installation of the VS!!!

If there are problems with the MS-Functions check your input parameters. That are the most error case. ("The biggest problem of the PC sits in front of it" Blush | :O

Is there any Macro that can be used to know if the function that is running is called from a worker-thread or the main program? It is needed to know without use any addictional static global variable or addictional parameter to the function.
thanks

This looks the solution:

if( AfxGetMainWnd()==NULL ){
   // Thread specialization
}else{
   // Main program specialization
}

Any comment will be wellcome

May be you can use something like this...

DWORD dwMainThreadId = 0;
DWORD dwProcessId = 0;
dwMainThreadId = GetWindowThreadProcessId( hMainWnd, &dwProcessId);
if( dwMainThreadId == GetCurrentThreadId() )
{
//Main Thread
}
else
{
//Thread specialization code
}

I have not tested this snippet.

Yes! your solution looks work better then mine

inline BOOL IsThisAThread(){
	return GetCurrentThreadId()==GetWindowThreadProcessId(AfxGetMainWnd()->GetSafeHwnd(), NULL);
}

	return GetCurrentThreadId()!=GetWindowThreadProcessId(pMainWnd->GetSafeHwnd(), NULL);
