Help on URLOpenStream () Tdr9982-Feb-04 0:22 Tdr998 2-Feb-04 0:22  Hello to Everybody, My name is Thomas, I am a student in computer science. I need to implement in visual C++, a code that requests something to a PHP database server using a url (ex.: "http://192.168.1.110/csa/csasql.php?tipo=select&sql=SELECT Cali_CardPresent,Acc_Operator,Acc_IR FROM IR_ERRORS " ), and the server returns the answer thats can be: + an error or a success and in case of success, in some cases can be followed by data. I first used to do this the function URLDownloadToFile(), but when the server is down, I have downloaded the file stored in the Internet cache. Its a big problem because I don't want cached files to be stored and retrieved because its was an past answer of not my last request. I would like that for each request the server sends a new answer, and not taking the cached file. I tried reconfigure IExplorer or bypass the problem using other ways but It is not so efficient... I dont know if there is any way to bypass the caching of files but I see there is another function: the URLOpenStream(). Maybe with this function, all requests are straight for the server, and therefore bypass the cached stored files? But there is another problem for me to use the URLOpenStream(): I am trying to understand how to implement the IBindStatusCallback interface, because I am not so experienced in C++ and if you would like to contribute with an example project in VC6++ that compile, I will be very thankful. Regards, Thomas.

In the dialog class I do some stuff and need to have handle for the window (dialog window). I use ::SetTimer and ::KillTimer and they require the handle (HWND type not CWnd type!) of the app. BTW.. Is there any example of how to use SetWaitableTimer? TIA! Re: newbie question of the day: How do you retrieve your app's HWND handle?
