And i'm using MOF code for authentication

C++

hres = pSvc->ExecQuery(
       bstr_t("WQL"),
       bstr_t("SELECT UserName,Password,Uid FROM HLDS where UserName='vinod'"),
       WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY,

Solution 1

Doesn't the += operator work?

C++

   string s = "SELECT UserName,Password,Uid FROM HLDS where UserName='";
   s += this->textbox1->text;
   s += "'";
hres = pSvc->ExecQuery(
   bstr_t("WQL"),
   bstr_t(s),
      WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY,
      NULL,
      &pEnumerator);

Take a look at the following article from here on Code Project ->http://www.codeproject.com/KB/mcpp/cpptomancpp.aspx#EX3. Particularly the section on managed strings.

Hope it helps.
