Unresolved external

[Sugi]

Hi all,

I knew that this topic has been posted, but still couldn't found
solution for my problem, so I post again.

I am using C++ Builder 6. I created just a button on a simple form.

This is the code on ButtonClick
ShowMessage(GetEnvironmentVariable("temp"));

and I got this error :
[Linker Error] Unresolved external '__fastcall
Sysutils::GetEnvironmentVariableA(const System::AnsiString)'
referenced from C:\TEMP\TEST\UNIT1.OBJ

I have already included sysutils.hpp, so how do i resolve this
problem?

Thanks in advance,
Regards,
Sugi.

Use something like this:

#include <winbase.h>
.
.
.
void __fastcall TForm1::Button1Click(TObject *Sender)
{
char str[255];

GetEnvironmentVariable("temp", str, -1);
Caption = str;
}

Olli.
