FIX: StillExecuting Property Returns Incorrect Value (182152)

MORE INFORMATION

In Visual Basic, True equates to -1 and False equates to 0.

When the Internet Transfer Control is executing, comparing the StillExecuting property with True fails. An alternative is to compare StillExecuting to any value other than False (0).

When the Internet Transfer Control is not executing, the StillExecuting property has the correct value of 0 (False).

Steps to Reproduce Behavior

1. Create a new Standard EXE project. Form1 is created by default.
2. Add the Microsoft Internet Transfer Control (Inet1) Form1.
3. Add a CommandButton (Command1) to Form1.
4. Insert the following code into the General Declarations section of Form1:

         Private Sub Command1_Click()
           Inet1.URL = "http://www.microsoft.com"
           Inet1.Execute , "GET"
           Do While Inet1.StillExecuting = True
             DoEvents
           Loop
           Inet1.Execute , "GET"
         End Sub
   
   					

5. Run the program. When you click on Command1, you receive the error:
   Run-time error 35764
   Still executing last request.

To work around the problem, do not compare StillExecuting to True. Instead, change the Do While condition to simply check for a non-zero value:

     Do While Inet1.StillExecuting
				

NOTE: This comparison will succeed where StillExecuting is 1, -1, or any value other than 0 (False). If the value of StillExecuting is compared against an explicit value such as 1, and this code is run with future versions of the control where the bug is fixed, the comparison may fail.
