How to check an Excel file is already open

There are no direct methods using Exel/Workbook object to find the functionality.

Work around is, we need to find out all open tasks, and from that we will see whether any task with name "Microsoft Excel"

Here in the below code, i have a sample Excel file with name "SampleXL".

Set Word = CreateObject("Word.Application")
Set Tasks = Word.Tasks
i=0
For Each Task in Tasks
    If instr(Task.Name,"Microsoft Excel - SampleXL")>0  Then
            i=1
    end if
Next
If i=1 Then
    print "Excel file is opened"
else
    print "No excel file opened with the name specified"
End If

Word.Quit

'sCon="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\Programming Samples\QTP\SampleXL.xls;Extended Properties=""Excel 8.0;"""
sQry="select * from [Sheet1$]"

oCmd.ActiveConnection = sCon
oCmd.CommandText=sQry

How to check a browser window is minimized

Extern.Declare micLong, "GetMainWindow", "user32" ,"GetAncestor",micLong, micLong 'This is the declaration for the referencing "GetMainWindow" with the GetAncestor method in user32.dll.
GA_ROOT=2

Just opened Gmail and checked whether the browser is minimized or maximized.

We cannot directly use Browser().GetROProperty("minimized") here.


Set oBrowser=description.Create
oBrowser("micclass").value="Browser"
oBrowser("name").value="Gmail.*"

hwnd=Browser(oBrowser).GetROProperty("hwnd")

hwnd = Extern.GetMainWindow(hwnd , GA_ROOT)
msgbox Window("hwnd:=" & hwnd ).GetROProperty("minimized")

The above code returns False if the Tab/browser is maximized else
returns True if the Tab/browser is minimized

The above code worked well with QTP and IE 7.

How to display occurances of a string in a Excel file

Following code helps find the occurrences of a string in a Excel file.

It will return the count as 0, if the string is not found
else returns the number of occurrences of the string

Dim oXLObj,oXLWBObj,olXLWSObj

Function FindStringOccuranceCount(sFileName,iSheetId,sSearchString)
    iCount=0
    set oXLObj=createobject("Excel.Application")
    Set oXLWBObj=oXLObj.workbooks.open(sFileName)
    Set olXLWSObj=oXLWBObj.worksheets(1)

    set cell=olXLWSObj.Range("A:Z").find(sSearchString)
   

    If cell is nothing Then
        CloseExcel()
        FindStringOccuranceCount=iCount
        Exit Function
    End If

    sFirstAddress=cell.address

    Do
        set cell=olXLWSObj.Range("A:Z").FindNext(cell)
        'set CurCell=olXLWSObj.UsedRange.FindNext(sSearchString)
        sCurrentAddress=cell.address
        'sCurrentAddress
        iCount=iCount+1
    loop while not cell is nothing and sCurrentAddress<>sFirstAddress

    CloseExcel()
    FindStringOccuranceCount=iCount

End Function

Function CloseExcel()
    oXLWBObj.close
    oXLObj.application.quit
    Set oXLWBObj=nothing
    Set oXLObj=nothing
End Function

x=FindStringOccuranceCount("C:\Test1.xls",1,"Uday")
msgbox x
