does Ranorex support fetching data from Excel document

Post by Laxmi » Tue Nov 10, 2009 11:46 am

Hi

We are looking to automate our application.
It is an excel based application.
When we login into our application, we have the abitlity to open some excel documents from with in the application. These documents are not stored in local machine in some path. They are fetched from the DB.
We place some data into the excel document which we call project and then calculate it and see if the out put cells in the project are getting populated with correct values.

I want to know if Ranorex has the abitlity to identify the excel sheets with cell names and does it identify the named regions in excel?

Also within excel, we have some custom controls created by us. Clicking on which would open new windows.
Can you please tell me if Ranorex would identify these controls.

These are our major requirements.
If these are supported, we would look at buying licenses.

Please reply ASAP.

Thanks,
Laxmi,

Using standard Excel Interop you can do most anything with Ranorex in Excel.
Here is a method I use for reading named ranges in from any sheet within Excel with Ranorex:

Code: Select all

        public static string[] ExcelReadNamedRange(Microsoft.Office.Interop.Excel.Application objXL, Microsoft.Office.Interop.Excel.Workbook objXLWorkBook, string strExcelFileName, string RangeName, string strSheet)
        {
            /************************************************************************
             * Function         : ExcelReadNamedRange(string strExcelFileName, string RangeName, string strSheet)
             *
             * Description      : This function will read and return the data of a named range of cells 
             *                  :  in the specified Excel workbook.
             *                         
             * Parameters       : objXL             - An existing Excel Object. Pass in NULL if you want to open & close excel within this function
             *                  : objXLWorkbook     - An existing Excel Workbook Object. Pass in NULL if you want to open a workbook/spreadsheet within this function
             *                  : strExcelFileName  - Full path and filename of the Excel spreadsheet to open
             *                  : RangeName         - Name of range of data to return (i.e. "MyRange")
             *                  : strSheet          - OPTIONAL - Name of the sheet in the spreadsheet the cell is on
             *                  :                   -            If not supplied will default to the 1st sheet.
             *                  
             * Return Type      : String array
             * 
             * Return Value     : Data from the cells for success, null for failure
             * 
             * Revision History
             * Date       : Author                    : Reason/Change
             * ---------- : ------------------------- : ------------------------------
             * 03/24/2009 : Chris Gendreau            : Initial Creation 
             * 07/10/2009 : Chris Gendreau            : Added pass in ObjXL & ObjXLWoorkbook
             * 08/18/2009 : Chris Gendreau            : Added check if Named Range is only 1 cell in length

As for your custom controls, what I suggest is download and install the Ranorex trial version. Use RanorexSpy to spy on your controls and see what information is available to you. Assuming your dev team follows standard operating procedure you should have no (or very few) immediate issues interacting with your custom controls.
If this or any response has helped you, please reply to the thread stating that it worked so other people with a similar issue will know how you fixed your issue!
