    Hi Robert, 

    Sorry for the delayed response. 

     

    I was playing around with the code and finally, I got a solution for this. I've replaced WaitAliasChild with WaitWinFormsObject method. This is working as expected and my code is successful now. 

     

    Here is the new code which fixed the issues. 

    If Aliases.cwConsole.WaitWinFormsObject("frmCrystalReport", 30000).Exists Then

     

    Thank you very much for your ideas and for helping me to fix the issues. I will be testing the new code and will get back to you if I get any further issues.

Hello Shankar, 

Thanks for your reply. 

 

  • I tried the unchecking 'Stop On Error' and it did work. But, I'd like to stop the script execution on error windows. If I disable this thing the script may not stop when there is actually an error object. Is that right? 
  • I've tried using the mapped name and I got the same error message for many times. That's why I tried using the full name. 
If Not Aliases.cwConsole.frmCrystalReport.Exists Then

It is fine if you enabled Stop On Error

 

The actual problem is occurring on this line,

Set Rep = Sys.Process("cwConsole.exe").winformsObject("frmCrystalReport")

not in 

If Not Aliases.cwConsole.frmCrystalReport.Exists Then

 

replace like below and try it.

Set Rep = Aliases.cwConsole.frmCrystalReport

    Common problem:

    How do you check the "Exists" property of an object that does not exist?  If the object does not exist, there is no object to have an "Exists" property.  To check for "Exists", you need to either use a "Find" method to search for the object or a WaitNNN method of some sort.

     

    I'd replace the code below with the following.

     

    If Not Aliases.cwConsole.WaitAliasChild('frmCrystalReport', 5000).Exists Then

    WaitAliasChild will wait the indicated number of milliseconds for the object to return.  If it returns sooner than that time, the object is returned immediately and the method continues without waiting the full time.  If the timeout expires, a "stub" object is returned which consists of ONLY the "Exists" property with a value of "False".

     

    This is the recommended best practice method of checking for existance.

      Thanks for this Robert Martin.

       

      It works when the Crystal Report object does not exist. But when it is available the checking fails again. 

       

      Scenario #1 - Crystal Report object does not exist. (Success)

      Both the 'IF' and 'IF NOT' conditions are working fine. Got the expected result. 

       

      Scenario #2 - Crystal Report object exists. (Failed)

      IF and IF NOT conditions gave the wrong result. It shows similar to Scenario 1.

       

      My code is ready when Scenario #2 works.

        Can you post in here your actual code you used to implement the "Wait" methodology? There may be a syntax or logic problem that can be solved.

    Hi Shankar,

    Yes, I tried this as well. The same error again. 

    Aliases.cwConsole.frmCrystalReport.Exists

     I'm trying the steps provided by Robert Martin.
