Error 12005 Trying to Call WINHTTPCONNECT Function in WINHTTP DLL from VB

Asked by lonefox_illuminus in WInsock, Visual Basic Programming, VB Controls

Tags: Visual Basic, 2008, VB, 12005 ERROR_WINHTTP_INVALID_URL

I am trying to call Winhttp.dll from a VB app. I specifically need to carry out this process using windows native DLL's, not COM objects.
When I run the attached code, I get the error 12005, could someone explain why, and offer a solution.
Please note my final solution will be adapted to run in an uncommon language (Omnis 7), so please keep this in mind for your replies.Start Free Trial
