That is tantamount to a challenge of the highest order. Now not only do I have to win that contest, but I have to do it well enough to impress Rama Programmer Guru Krishna, hehe. Well I don't fully understand the problem yet, but I have got the code working by not using a bool and rather using a String*. I assume it has some managed types explanation behind it.

Niko Tanghe26-Jul-02 1:54 Niko Tanghe 26-Jul-02 1:54  Is it possible to assign a thread to a single processor in C++ with Visual studio ? Re: dual processor - multiple threads. Tomasz Sowinski26-Jul-02 2:14 Tomasz Sowinski 26-Jul-02 2:14  Check SetThreadAffinityMask. But better be sure what you're doing.

Paul M Watt26-Jul-02 5:40 Paul M Watt 26-Jul-02 5:40  If you are simply concerned that windows is optimizing your threads processing effectively, you should know that it runs all of your threads on different processors until it has to double up on a processor. So it tries to maximize the through put of the multi-processors parallel processing.

Current Process Path - Not Name Giles26-Jul-02 1:32 Giles 26-Jul-02 1:32  In MFC, how would you go about getting that PATH of the current executable - AfxGetAppName is not enough. Help Re: Current Process Path - Not Name Tomasz Sowinski26-Jul-02 1:46 Tomasz Sowinski 26-Jul-02 1:46  __argv[0] should do the trick. It's global variable in MFC.

Re: Current Process Path - Not Name - Correction Tomasz Sowinski26-Jul-02 1:50 Tomasz Sowinski 26-Jul-02 1:50  __argv[0] will contain incomplete path when you launch the program from command line. Seems that most reliable way of getting the path will be ::GetModuleFileName. Tomasz Sowinski -- http://www.shooltz.com - It's for protection - Protection from what? Zee Germans? Re: Current Process Path - Not Name - Correction Giles26-Jul-02 2:24 Giles 26-Jul-02 2:24  Cheers. I had a feeling about GetModuleFileName, but thought it would only provide the filename again.

It'll give you complete path, including filename. If you want to have only directory part left, copy the filename into CString, then use CString::ReverseFind and CString::Left.

I tried to outsource some common classes from some existing projects into a shared static WIN32-library. The classes were implemented into a MFC dialog application and make use of MFC templates such as "CMap" and also of MIDL base_types like "hyper"... The problem is: If I try to compile those classes within a static WIN32-lib workspace, Visual Studio mourns about that "hyper", "CMap", etc. are unknown (Error C2501). Although I've set the option that I want to use MFC in this library. I think that I have to link some more headers or set some switches in the properties of the static lib workspace... But I found no suitable hints at the MSDN library at all! So... Maybe someone can give me a tip how to implement "hyper", "CMap" & Co. into a static WIN32-library...??? *pls* Many thanks in advance! With best regards, Andreas Dilling Trouble with DestroyWindow klm26-Jul-02 0:58 klm 26-Jul-02 0:58  Hello, when i exit my application, i get this message from the debugger: Warning: calling DestroyWindow in CDialog::~CDialog -- OnDestroy or PostNcDestroy in derived class will not be called. What is the meaning of this Warning? Thanks for your Help! Re: Trouble with DestroyWindow Tomasz Sowinski26-Jul-02 1:03 Tomasz Sowinski 26-Jul-02 1:03  This means that you're having problems with lifetime of your dialog. Is your dialog main window of your app? Tomasz Sowinski -- http://www.shooltz.com - It's for protection - Protection from what? Zee Germans? Re: Trouble with DestroyWindow Scott H. Settlemier26-Jul-02 1:47 Scott H. Settlemier 26-Jul-02 1:47  That msg occurs when you have a class instance that is being destroyed before its window. The class destructor will automatically destroy the window for you, but since this is done from the destructor, the instance is no longer around to handle any messages. This is sometimes the behavior you want, just make sure that your destructor AND OnDestroy both call a cleanup routine in common. Re: Trouble with DestroyWindow klm26-Jul-02 1:51 klm 26-Jul-02 1:51  Hello Thomas and Scott, Thank you very much for your help! I have found the error: I have a view, he create via new dialogs. When i exit the dialogs, in my OnDestroy-function of the view, i delete the dialog. Now i delete the dialogs in the destructor of my view. quick question about message reflection Anonymous26-Jul-02 0:56 Anonymous 26-Jul-02 0:56  I've just started to read about this. seems like custom controls can have relected messages. so a regular old button added from the toolbox is not able to do reflection?

Re: quick question about message reflection ns26-Jul-02 1:29 ns 26-Jul-02 1:29  The article I was reading was adding handlers for messages starting with = via the classwizard. One selects the class of the control and then handles the = message. Since I added my button through CW I dont have a control class for it in my CW. Thats why I incorrectly deduced that standard controls couldnt refelect. Thanks, ns comctl32 crashes alaulu26-Jul-02 0:43 alaulu 26-Jul-02 0:43  Hi All ! One problem pursues me for a few years already: all my Win32 apps, written in VC++ (5.0-6.0), crash on the second run under debugger. Toolbar code in comctl32.dll causes access violation. In more details: 1)The crap arises only when the app is run 2 times successively from the VC++ IDE. When running my app standalone, all's ok. 2)The program crashes when a mouse is moved over the toolbar. WM_MOUSEMOVE is finally dispatched to DefWindowProc() in comctl32.dll, and there fails. The mouse coordinates seem to be correct. 3)If toolbar is hidden, it's allright. 4)This bug seems to be not accidental concatenation of circumstances: this happened on different Windows versions, under both VC5 and VC6, after many reinstallations of the VC++ and OS etc, and, finally, with all my Win32 GUI apps - independently of tyhe architecture of the app, and of the way I use tollbars (containing ReBar, different styles, etc.) 5) The bug arises and disappears from time to time, during the course of program development. It seems that it depends somehow on the size of the .exe or something like that. Anyone ever faced this problem ? Any help or hint would be appreciated ! Thanks in advance ! Plugin Extensions laphijia26-Jul-02 0:35 laphijia 26-Jul-02 0:35  I was wondering what are the principles of creating a plugin extendable program. I mean a program that accepts custom functions being created by third party developer, following certain rules. Like Winamp, or Windows Media Player, that with plus has the Speaker Enanchement pluging: you install the plugin and there is a new Item in the Windows Media menu. Is there any tutorial, guide, etc about this? Thank you. "Nelle cose del mondo non e' il sapere ma il volere che puo'."

Zee Germans? Re: Plugin Extensions Chris Losinger26-Jul-02 4:25 Chris Losinger 26-Jul-02 4:25  for the plugin system i use, i simply came up with a COM interface for the plugins and just told people that if they want to write a plugin for my apps they must: create an ATL object with this interface, name the object thusly, and place it in this folder. at runtime, my app scans that folder and finds all the DLLs there. then it does a CreateObject call on each of "%DLLNAME.MyInterfaceName" . if that works, the object is a plugin. it works great. i can elaborate, if you'd like -c To explain Donald Knuth's relevance to computing is like explaining Paul's relevance to the Catholic Church.
