READ With a Control Property Hangs the VBDOS.EXE Environment

• Microsoft Visual Basic Standard and Professional Editions for MS-DOS, version 1.0

SYMPTOMS

Using the READ statement to assign a value to a control property hangs the interpreter environment or incorrectly produces an "Out of String Space" error message.

STATUS

Microsoft has confirmed this to be a bug in the Standard and Professional Editions of Microsoft Visual Basic for MS-DOS, version 1.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

The READ statement allows you to read data that is stored within your program in DATA statements. However, when the environment unexpectedly encounters a property name instead of a variable name to store the data in, it hangs the interpreter or produces an "Out of String Space" error message. This does not happen in a compiled program.

The following steps can be used to reproduce this problem:

1. Start VBDOS.EXE.



2. From the File menu select New Form... (FORM1.FRM). Form1 is created by default.



3. Exit the Form Designer, save all changes.



4. Add the following code to the Module Level of Form1:

   
         DATA 10 




5. Add the following code to the Form_Click event procedure of Form1:

   
         SUB Form_Click()
             READ BackColor
         END SUB 




6. Press F5 to run the application. Notice that the READ statement changes to random characters and the environment hangs or gives an "Out of String Space" error message.
