2. Set the breakpoint correctly in the control code. 3. Specify Explorer.exe as executables used to debug. In Visual C 5.0, you can set up from the Project menu, and the method is to click Settings and select the Debug tab. Under "Executable Files Used to Debug Session", specify Explorer.exe or click the arrow and select "Default web browser". 4. Under "Program Parameters", type "-new". This will initiate the new Internet Explorer process that the debugger can join, which is opposite to the new thread. Another option is to perform steps 1 through 3, then continue to perform the following steps: On the Start menu of the Windows taskbar, select Close System. 5. When you appear, click Close All Programs and Log in with Other Users, and then hold down the Ctrl Alt Shift key and click No. In this way, the Windows shell including the taskbar will be turned off, but the Windows session will not end. To switch between applications, use the Alt Tab key. To start another application, press CTRL Alt Delete to start with the Task Manager. 6. Once the Windows shell is completely closed, start the debug session and ignore a warning that is unavailable for the debug symbol of Explorer.exe. 7. Open a browser or resource manager window and specify the address of the HTML page of the reference control. After loading the page, the focus will jump to the debugger, and the debugger will pause at the first breakpoint set. After debugging the control, you can use the Task Manager to restart the housing. 1. Under Windows 95, double click on any location of the desktop to open the Task Manager. Under Windows NT, press CTRL Alt Delete and click the Task Manager button. 2. On the File menu of Task Manager, select "Run", then enter the path of Explorer.exe to restart the housing.
