netshareenum()

[maya123]

The following code compiled find and when I run it, I am getting error 1113
which means the following
No mapping for the Unicode character exists in the target multi-byte code.

I dont know what is wrong with the parameters being passed to the
NetShareEnum () function.

I am using VS.net 2003 to compile.

NetShareEnum (http://msdn2.microsoft.com/en-us/library/aa380481.aspx) takes UNICODE string as the 1st parameter, so if you pass ASCII, it is wrong

Yes, I fixed the problem using the following code,

char name[] = "moscow";
wchar_t SomeUnicodeStr[1024];
MultiByteToWideChar(CP_ACP, 0, name, -1, SomeUnicodeStr, 1024);
When I run, I get 1326, logon failure, should I pass any other value in the first paramter?


res = NetShareEnum ((LPSTR)SomeUnicodeStr, 502, (LPBYTE *) &BufPtr, -1, (LPDWORD)&er, (LPDWORD)&tr, (LPDWORD)&resume);

well, actually I've confused you with that UNICODE parameter, it depends on SDK version you use. simply have a look in appropriate header file to be sure. and you should cast the 1st parameter to LPTSTR to be consistent with your SDK.

I guess you run the code under correct permissions (e.g. levels 2 and 502 require Administrator, Power User, Print Operator, or Server Operator group membership)
