a question about SendRequest Function of InternetSession class
Posted on 2003-11-05
I write a ATL Service program using VC 6.0, and some problems happened are very strange.
This program connect a website page in Internet. by post method using the SendRequest function of InternetSession class. All the connecting codes are writed in a function called "SendOrder" in a dll file, and the Service program use the function of this dll. The "SendOrder" will be run every time pre minute in the service program. The operation system is WIn2000 professional. My computer connect Internet through the WinGate proxy Server in another computer.
When I run this service program from the WIndows Service Manager, The first three time connections are successful, but from the fouth connection, the "SendOrder" function will be broken and every code after the SendRequest will no longer run. I don't know what cause this program?
But if I run the Service program directly by clicking the exe file, all the connections will ok.
who can help me?
