What i realy wanted to do was replace some 'C' code with a piece of VB.ÿ The 'C' code was :-

// Get a VB string from a text pointer

STDAPI_(BSTR) GetStringFromLPSTR(LPSTR tptr)
{
BSTR rptr;

char tbuf = '\0';
ÿ if(!tptr) {
ÿ ÿ ÿ rptr = SysAllocString((OLECHAR *)&tbuf);
ÿ ÿ ÿ }
ÿ else {
// Why do it by length? Because SysAllocString looks for a double
// null - which may not be present
ÿ ÿ ÿ rptr = SysAllocStringByteLen(tptr, lstrlen(tptr));
ÿ ÿ ÿ }
//ÿ MessageBox(NULL,(LPSTR)rptr,NULL,0);
ÿ return(rptr);
}

It works fine, but i wanted the functionality within VB (i dont want to have to distribute a seperate 'C' Dll)

I have added a code example to do this.ÿ See <A HREF = 'http://www.freevbcode.com/ShowCode.Asp?ID=2643'>http://www.freevbcode.com/ShowCode.Asp?ID=2643</A>.

Note that this example is for Unicode strings.ÿ I don't know if this is what is used in C.ÿ But if it's not, there are also instructions for how to change the code.
