Hi all,
The other day I developed a small test application in VS2005 CLI and include an ODBC class that I downloaded from CP to be more specific it was this: A set of ODBC Classes[^]
I included it into my project and changed a few setting of the project and everything worked. Untill I ran it on another computer. When I received a "application configuration is incorrect..." so I removed the ODBC class from the project, without changing any of the settings and tried again and this time it ran on the other computer.
Why did this happen ??? Can anyone please help.
Many thanks

Hi,
I have a dll written in C# that works well when i use it in .net environment. i need to load it from unmanaged code. according to MSDN documents i have used "REGASM /tlb.... " and "GACUTIL /i ..." for calling managed code from unmanaged code. it worked in some of my samples. but unfortunately i have an odd problem now.
i have created an OCX control in VB (not vb.net) an i called some functions of my managed DLL. when the managed function is called, it doesn't works completely well. i mean some of processes in managed code work well but some others don't work well. for example where i use RASCryptoServiceProvider Class it fails. the odd thing is that this dll works perfect when i call it from .net environment.
it has taken a lot of time from me. do you have any advice? HELP!
thanks
ps: there is no data passed between managed and unmanaged code then i thins it is not a subject of marshaling

This is the managed C++ board. You may want to post this question on the Visual Basic board[^].

The arguments are passed in to your main method, if they are passed in at all. I thought they were, they sure are long gone by the time you get to a button event.

Hi all,
I have read the article on MSDN about Redistributing Visual C++ Files, but was left wondering whether there isn't another way of compiling ones application (fiddling in the project properties or something) so that it can run on another computer (without having to run any of the Microsoft Visual C++ 2005 Redistributable Packages) ??
Many Thanks

Sure, try Googling: Fiddle with Project Properties
Seriously though, you can't avoid installing the C Runtime library but most of the others (MFC, ATL, etc.) can be statically linked by "fiddling".

You can link statically to the dlls, which makes your app bigger, as it will copy them into your exe.

This normally works for me
char* echostring = (char*)Marshal::StringToHGlobalAnsi(ip).ToPointer();

you would have to point to ip[0] or &ip
echostring = ip[0];// << this will make it be the address of the first position[0] of the string same as &ip.
by the way this is for C++.

echostring = ip;
is fine.
The error is here:
ip = txtIpAdd->Text; //textbox
You can't do that
As programm3r mentioned, something like this should work:
char *echostring;
char ip[RCVBUFSIZE]; //32
const char *chars = (const char *)(void *)Marshal::StringToHGlobalAnsi(txtIpAdd->Text);
strncpy(ip, chars, RCVBUFSIZE);
Marshal::FreeHGlobal(System::IntPtr((void*)chars));

Hello,
I converted VS2003 code to VS2005 (C++, C#).
I try to use DLLs which use: System::Runtime::InteropServices.
Do you know if it is OK? I got runtime error...
Thanks!

You're not giving us much to work with
I'm going to guess it's not ok, since you get a runtime error.
Does debugging yield any clues?

Firstly, this is incorrect forum. You should have posted this here: http://www.codeproject.com/script/comments/forums.asp?forumid=1647
Secondly, here is answer to your question:

My contract rate is > $100 an hour. Alternatively, you can do your own homework, and then I'll help for free, when you ask specific questions that show you've done somethig yourself.
I suspect you meant to post this in the Visual C++ forum.
