VisualTest - Using Excel Application

Our Automation suite results were in text files. I wanted to create the excel file as results file. You can get to know more about Results Reporting. I used Excel VBA for this. It has simplified my task to prepare the compiled results for entire execution.

Similarly I will write, how to do the same thing by using VB script later....

Code: To check Excel availability in the system

 
'--------------------------------------
' Method : IsExcelAvailable
' Author : T.Palani Selvam
' Purpose :   Checks whether excel application is available or not.
' Parameters: - Nil
' Returns :   Returns integer, whether true or false.
' Caller : 
' Calls  : 
'--------------------------------
Function IsExcelAvailable() As Integer
Dim objExcelApp As Variant

ON LOCAL ERROR GOTO Errhandler

 IsExcelAvailable = False
 objExcelApp = OleCreateObject("Excel.Application")
 Sleep 0.5
 OleReleaseObject(objExcelApp)
 IsExcelAvailable = True
 Exit Function

ErrHandler:
   'LogWrite("[Failed At] " + ERF(0)+ "("+ str(ERL) +") :  "+ ERROR$ + " .Error Number: " + str(Err),1)   'Actual location.
   'Logwrite("[Trapped At] "+ ERF(1)+ "("+ str(ERL(1))+ ")",1)   'Trapped location.
  Logwrite("Excel Application is not available.", 2)
End Function

Code: To Read Excel data

 
'---------------------------------------
' Method : ReadExcelCells

'  and checks result automatically, while completing a test case.

' Returns :   - Nil -
