You shouldn't type a very long line in VB. It's really inconvenient. You may write it to a file such as *.txt, then load it to your string var. It's convenient that: you can easily repair the text.:cool: GF bos

Thank you for your great help.

Hi Boni, Boniolopez wrote: How can I say the IE that if it meets a tag "Transistor" to take a picture "transistor.gif" You actually don't say it to IE. Yes, you are supposed to use XSLT. What XSLT do? You have some XML document, and in XSLT you say how to transform it. Result of transformation is usually another XML document, but not allways. You can have XSLT transformation which will output CSV, plain text or whatever. So you will have XLST which will transform XML tag "Transistor" into tag "<img src='transistor.gif' />" The point of use CSS is in absolute positioning, which allow you to arrange images on page. Example: <img src='transistor.gif' style='position:absolute;left:5px;top:5px'> will render image with upper-left corner 5 pixels from top of the page and 5 pixels from left border . btw I've learnt XSLT from (MSDN[^]) I think it's good for u to learn it too (whereever), cuz I think XSLT is very powerful and useful technology... It's not so difficult as it might look ;) I hope these information are helpfull... I don't want to write it all, a) it would be so loong post ;) b) I want to leave something for u :) David Never forget: "Stay kul and happy" (I.A.)

The code compiles fine in VC++ .NEt 2003. Try something like on the problematic compiler. template class a {}; class b { friend class a; }; Kuphryn

Thanks all for your help

I'm not sure if this technique is possible in Windows, but it is under Unix with ELF loaders. Write a shared library (.so - equivalent to .dll in Windows), in which you define extern "C" void* malloc(size_t s). Then have the shared library to be preloaded before all other DLLs are loaded. Then the linker will not link the system malloc since it has already been loaded. To chain your malloc with the system's malloc, you simply load the system shared library dynamically in your shared library, and retrieve the pointer to the system's malloc. So, in your DLL you will have code kind of like this: void* (*real_malloc)(size_t); DllMain() { HANDLE h = LoadLibrary("whichever_dll_that_contains_malloc.dll"); real_malloc = (void*(*)(size_t))GetProcAddress("malloc"); } extern "C" __declspec(dllexport) void* malloc(size_t s) { do_some_stuff(); void* ptr = real_malloc(s); return do_something_more_perhaps(s); } Then have the linker preload this DLL. I'm not sure it's possible in Windows, but I have a hunch it is. I know it's possible to hijack DLLs, and that's basically what this is. Needless to say, you'll need to link against the runtime dynamically. -- Suche Wissen über Alles. Der Student

Hi Nick, thank you so much for the answer. But can't windows notify me with an event, when the mouse is over my rectangle? (I could imagine to register the rectangles "contain"-method somewhere(?)) I fear, that if track mouse for all of my 1000 objects (not only rectangles but even more complicated figures) for each move this will slow down the PC very much. Thanks for your time, boni

The file and line number information is not exposed through the BCL or through compiler constants or directives. The best you can do is a Strack Trace from the System.Diagnostics namespace.

Hi, Thanks for this advices. But I needed a regular expression. The reason is, that I have a bunch of files which are from other providers. And they produce many warnings(which are mostly ok).

That's Intellisense doing that. Smart Tag support will show up in VS.NET 2005... RageInTheMachine9532 "...a pungent, ghastly, stinky piece of cheese!" -- The Roaming Gnome
