CInternetSession Problem

[Amar Sutar]

Hi, I am writing an appliction which downloads MJPEG stream from IP camera. My application supports many IP cameras at a time. So i need to download several URL at a time from single instance. But the problem is when I add my fifth camera my application gets hanged. So is there any limit on how many URLs we can open using CInternetSession's OpenURL method? From my application I am able to open upto 4 URLs for one instance. For fifth URL my application give "timeout" exception. Code: CStdioFile* m_pFile[5]; CInternetSession m_inetSession[5]; for(int iIndex = 0; iIndex < 5; ++iIndex) { m_pFile[iIndex] = m_inetSession[iIndex].OpenURL (cstrUrl, 1, INTERNET_FLAG_TRANSFER_BINARY | INTERNET_FLAG_RELOAD); . . } Thanks in Advance. Amar :)

Since CInternetSession class is a wrapper around InternetOpenUrl(), you could temporarily change your code to use InternetOpenUrl() instead. When/if it fails, you can call GetLastError() to find out why.

GetLastError() returns error code 12002.

From the docs: ERROR_INTERNET_TIMEOUT 12002 The request has timed out. Are you sure the URL is valid? Mark
