NetShareEnum more problems

Ultimately I'm trying to make a combo box typedown the autopopulates itself by enumerating the shares of the servername that is typed into the box.  (i.e. just like Start, Run, \\Someserver\ <- at this point the shares are enumerated and populated in the combo box and the combo is expanded.)

Anyhow, In my production code I would be getting the servername from a call:

wchar_t szTmp[256];
GetDlgItemText(hDlg,IDC_COMBO2,szTmp,256);

How do I pass the servername to NetShareEnum.  (I've added some Proof of concept code I can't even pass a server name without it giving a error of 1113 or it just plain blowing up.  Any help would be great.
