To generate random numbers, use Random class.
Not so detailed, I know, but you post wasn't that clear...

Have you looked and tried to follow what the error description says

It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.

Is the virtual directory configured as an application in IIS?

Is the GDIPlus functionalty in .Net threadsafe?

e.g For Bitmap class, the MSDN states "Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe. ".

I am using the GDIPlus functionality inside .Net web services, is that safe?

Thank you,

Using a C++ function (defined in a dll) with char* param [modified]

Hi All,

I'm reasonably new to C# and have recently been coding parts of a C# user interface which operates in tandem with a C/C++ back-end. Things have been going O.K. until I had to make use of a function, whose prototype looks like this:

int functionName (const char* param1, const char* param2, char* nastyParam)

In my C# code, I have been dealing with the const char* params by mapping them to C# strings...that has been working quite well. Now the problem with nastyParam above is the intention is for the function to (possibly) return some string value to the caller via nastyParam. The following is what I have done thus far for the function above:

...<br />
      private static extern int functionName(<br />
            [MarshalAs(UnmanagedType.LPStr)] param1,<br />
            [MarshalAs(UnmanagedType.LPStr)] param2,<br />
            [MarshalAs(UnmanagedType.LPArray)] IntPtr nastyParam);

I've been trawling the net for solutions and came across a suggestion which involved mapping the char* to a C# IntPtr (as above)...the explanation in that article made sense to me, so I gave it a go but no luck thus far.

Anyone have any ideas?

cheers!

Hi,

you want a StringBuilder of sufficient capacity.
And it would be safer to pass the capacity (of buffer size) as a parameter as well
(so your C/C++ function can be made safe, in order to prevent buffer overflow problems).

An executable is made whenever you compile your application. It resides in the Debug or Release folder of your project.

Please help me to find a .NET cording.
