QTP Descriptive Programming

 1. logic or function of counting the no of subfolders under the main folder in tree structure.

 counter = 0
Function CountFolders(currentFolder)
    for each folder in currentFolder.SubFolders
        counter = counter + 1
        CountFolders(folder)
    Next
End Function

CountFolders
(CreateObject("Scripting.FileSystemObject").GetFolder("d:\temp") )
MsgBox(counter)
It counts only first level subfolders :)))

FCount = 0
 Set oFSO = CreateObject("Scripting.FileSystemObject")
  Set oFname = oFSO.GetFolder("D:\C:\Documents and
  Settings\cc_gubhi\Desktop\Gpubhi_folder") ' Folder Path
  Set vFiles = oFname.subfolders
  For each vFileItem in vFiles
  FCount = FCount + 1
  Next
  msgbox FCount

  Set oFSO = Nothing
  Set oFname= Nothing

   Set FSO = CreateObject("Scripting.FileSystemObject")
   Set TestFolder = FSO.GetFolder("C:\Documents and Settings")
   Set SubFolders= TestFolder.SubFolders
   MsgBox(SubFolders.Count)


1   What is use of library file and what is contains.?
2  What is difference between writing discripting programming and  writing
  code in library file.?

All the thing s that you can not do in the QTP can be done in vb script eg.
  implementing business logic.. This code can be written in the vb script in
  the library file. using library files you can separe the code so u will get
  kind of modularity in the code.

 2. When the objects in the AUT are dynamic in nature the we can use DP for
  identifying the objects DP code can be written in the library file.

  DP is a kind of programming which eliminate the existence of the OR.

   You can pass the property value pair to identify the object or Use
  Description object to do the same..

how can write a discriptive program to check first five check boxes out of ten check boxes.
Dim strChkBox
Dim intCntr
Dim intMaxChkbxCnt
Dim intTotalChkboxes

Set strChkBox=Description.create()

strChkBox("micclass").Value="WebCheckbox"

Set
intMaxChkbxCnt=Browser("YahooMail").Page("YahooInbox").ChildObjects(strChkBox)

intTotalChkboxes=intMaxChkbxCnt.Count()

For intCntr=1 To intTotalChkboxes

    If  intCntr<=5 Then
        Browser("YahooMail").Page("YahooInbox").WebCheckBox(intCntr).Set
"ON"

    Else
        Exit For
Next

 If an  object attributes are changing in runtime, it is different. Often we can
  handle dynamic changes by using regular expression, but sometimes RE doesn't
  help. Here is an example:


  Static Object Description:

          Set oDesc = Description.Create()
          oDesc("html tag").Value = "IMG"
          oDesc("image type").Value = "Plain Image"
          oDesc("html id").Value = "cal.*BOseries::Calendar::.*::on_sale::0"
          oDesc("micclass").Value = "Image"
          oDesc("file name").Value = "cal.gif"
 
  Dynamic Object Description:


          Set oDesc = Description.Create()
          oDesc("html tag").Value = "IMG"
          oDesc("image type").Value = "Plain Image"
          oDesc("html id").Value = "cal.*BOseries::Calendar::.*::on_sale::0"
          oDesc("micclass").Value = "Image"
          oDesc("file name").Value = "cal.gif"
  *        oDesc("index").Value = ActualIndex*

Sort out data in ascending/descending order in data table

 DataTable.ExportSheet "D:\Sort.xls" ,"Action1"
  RowCnt = DataTable.GetSheet("Action1").GetRowCount
  Set ExcelApp = CreateObject("Excel.Application")
  ExcelApp.Application.Visible = True
  Set Book = ExcelApp.Workbooks.Open("D:\Sort.xls")
  Set Sheet = Book.Worksheets("Action1")
  Sheet.Range("A2:A" &(RowCnt+1)).Sort Sheet.Range("A2")
  Book.SaveAs "D:\Sorted.xls"
  ExcelApp.Application.Quit
  DataTable.ImportSheet "D:\Sorted.xls", "Action1", "Action1"


RowCnt = DataTable.GetSheet("Action1").GetRowCount
  ReDim Arr(0)
  If (UBound(Arr) < RowCnt) Then
          ReDim Preserve Arr(RowCnt-1)
  End If
  For i = 0 to (RowCnt-1)
          Arr(i) =
  DataTable.GetSheet("Action1").GetParameter("RollNos").ValueByRow(i+1)
  Next
  For i = 0 to UBound(Arr)
      For j = i+1 to  UBound(Arr)
          If (Arr(i)   Arr(j)) Then
                          Tmp = Arr(j)
                          Arr(j) = Arr(i)
                          Arr(i) = Tmp
                          i = i - 1
              Exit For
          End If
      Next
  Next
  For i = 0 to (RowCnt-1)

  DataTable.GetSheet("Action1").GetParameter("RollNos").ValueByRow(i+1)
  = Arr(i)
  Next
