RE: passing string array to C++

Hi

The .NET P/Invoke Layer will help to pass the ansi version string to
unmanaged dll.
Here is a simple test. You may have a try and let me know the result.

[C++]
CPPDLL_API long MyAdapt( long g, char **strings, long numStrings)
{
for(int i=0;i<numStrings;i++)
{
printf("%s \n",strings[i]);
strings[i][2]='A'+i;//Change the string
}
return 0;
}

[C#]
[DllImport(@"..\..\..\CPPDLL\Debug\CPPDLL.dll",EntryPoint="MyAdapt",CharSet=
CharSet.Ansi,SetLastError=true)]
private static extern int MyAdapt(int g,[In,Out] string[] users, int
numUsers);

public static void InteropStringArray()
{
string[] strs = new string[]{"Hello","World"};
int rt = MyAdapt(2,strs,2);
foreach(string s in strs)
{
Console.WriteLine(s);
}
}
[STAThread]
static void Main(string[] args)
{
InteropStringArray();
}

BTW:
I am not very familar with Embeded develop very much, the code above should
work but I tested only on .NET framework.
For compactframework or evc issue, you may try to post in the newsgroup
below.
