char szPath[_MAX_PATH], szBase[_MAX_FNAME], szExt[_MAX_EXT];
GetModuleFileName(NULL, szPath, sizeof(szPath));
_splitpath(szPath, NULL, NULL, szBase, szExt);

Call GetModuleFileName(), and then PathFindFileName() on the full path.

I am going to develop apps for autocadd. I have some ?'s.

Some customers only have AutoCad2004 or above.
I would like to use c# for all dev, but I want my screens to appear like they are part of the Autocad application. Some will be extremely complicated. Speed is an issue also

It must be compatible with 2004 or above. I cannot expect customers to use any energy at all to use my products

With those in mind, what version and should I go for MFC or .NET and, if .NET can it be c# or am I forcerd to use c++.net?

Can you give advice. Obviously I woulkd prefer c# for ease of use.
thanks,
nick

I'm not an expert yet, but I play one at work. Yeah and here too.

What does Autocad expose to allow you to write plug ins ? Is it COM based ?

yes its com based. But I answered my question. Because to modify you must wrap the ADS library so its easier to do MFC.

thanks for helping though

If you're targeting AutoCAD 2004, then you'll be forced to use c++. The .NET framework is only supported in AutoCAD 2005 and 2006. Also note, with c++ you'll be forced to use Microsoft Developer Studio 2002, NOT 2003 and AutoCAD itself is based on that version.
If you need more questions answered, please feel free. My company (http://www.cadfx.com) does this all day as we specialize in AutoCAD developement (but not limited to).

CMenu menu;
menu.EnableMenuItem(ID_MENU00, MF_GRAYED);

}

but the result is an error of 'debug assertion failed'

Re: Change the property of a menu

It doesn't work that way. When you have a menu item selected in the IDE, there are two messages you can catch. One is the click event, the other is called just before a menu item is shown. You keep a bool in your app to tell you if a menu item is disabled, and in that method, you take the menu item ( which is passed in from memory, as a pointer ), and you set if it's enabled or not using that boolean value. The same goes for check marks, etc. Any change to a menu items state happens in this event handler.

The preferred method for this is in the ON_UPDATE_COMMAND_UI() handler.

It would help if you gave us the line in question, but the second error usually means that you have precompiled headers turned on, and you've not included stdafx.h

Won't that lead to a part of the message like: "... while looking for precompiled header."?

Check for a missing parenthesis, brace, comment, semicolon, or #endif. The file must also end with a carriage return–linefeed pair.

How to detect the browser version?

4-May-05 3:05

This works fine for me:

char szBuffer[64];
HMENU hMenu = GetSystemMenu(hWnd, FALSE);
GetMenuString(hMenu, 0, szBuffer, sizeof(szBuffer), MF_BYPOSITION);
GetMenuString(hMenu, 1, szBuffer, sizeof(szBuffer), MF_BYPOSITION);
GetMenuString(hMenu, 2, szBuffer, sizeof(szBuffer), MF_BYPOSITION);

Dear all,
How to detect what kind of browser is running and its version? For example, Netscape or IE; IE 5.0 or IE 6.0, ect.
Best regards,

David Crow3-May-05 16:51

3-May-05 16:51

Your question cannot be answered in its current form (as more than one browser can be installed at any given time). If you want to know the default browser, simply use FindExecutable().

Yes, just use GetFileVersionInfo() and VerQueryValue().
