Regarding the tool for finding functions and decalaration syntax in windows dll

[C# Programming]

Hi to all

I was interested in listing the sql servers available.
I found some code " using System.Runtime.InteropServices; "

Code is used like that for using windows dll.
For that we need to define the method that we want to use
as follows :


[DllImport("odbc32.dll")]
private static extern short SQLAllocHandle(
short hType,
IntPtr inputHandle,
out IntPtr outputHandle);

So I want to know that is there any tool to find the declaration of the functions available in the DLL. Please lemme know how can I find the tool to do the same ?

If I use IDSAM then it gives the same for .NET libraries only not for windows library.

Thanks in Avdvance
