Handling multi-dimensional array in vbscript

Was trying to build excel data provider, which can be used for Test Complete and QTP scripts. Created a VBScript to keep all excel contents into a multi-dimensional array.

Problem
Declared array with lower limits and then used ReDim to fix with right count. But I was able to retrieve the data only upto the initial array size.

Solution:
Tried different ways. Then declared array without any size as given in below code.

Code:

MSN Money Quotes

Few months back, I was searching a solution, which can get the current stock value for the given quote. I did not find proper solution to get current quote. I have done few VBA procedures in Excel, to do few more calculations after getting current stock quote.

I found Microsoft's Excel 2003/2002 Add-in: MSN Money Stock Quotes. It can be installed with Excel 2007 version also. This Add-in is very useful to the people, who wish to maintain or track their stock investments. It is used only for US stock markets. Microsoft provides better online help to this addin as MSN MoneyCentral Stock Quotes help.

However I cannot use this add-in for NSE or BSE markets. I used selenium to retrieve the quote from net.

Closing Excel instance by VBScript

We have a test suite for Excel plug-in. Silktest built-in function does not work for Excel 2007. It is working fine for Excel 2003. Silktest is unable to close the Excel 2007 instance. We used Taskkill to kill the excel. It has created few other issues. I was looking for alternative solution. So I decided to write a vb script and got success. I have given the code below.

VBA - Extract Pictures from Excel

Last month, I have written Excel Automation Using VBScript. Today this post is to extract Pictures from Excel. Generally We can not use Export method for pictures. But we can use for Excel charts. I tried to extract our SVG chart image by macro and I succeed on it. I got help from Export pictures from Excel Below I've given the VBA Macro code.

Excel Automation Using VBScript

Using VBScript, we can automate most of the Excel verification activities. In one project we can export reports to Excel. I have to verify the cell value, font color and Background color. It is difficult task to verify each cell property by any GUI testing tool. All tools are used to identify Excel Grid (Workbook) as Custom Object. I am using VBScript to read the excel contents. Another advantage, you can use the VBScript against different versions of Excel such as 2002, 2003 and 2007. But you need to change the code for Excel 2003 and 2007, if you have done by using GUI objects.

Below I put one Visual Basic script code. It reads the given excel file and put the details of each cell into a log file. Copy all contents from below textbox and save it as MyExcel.vbs and try to run this VBS file. You can run this script by using any GUI Testing tool. Command line call should be cscript MyExcel.vbs sExcelFile iStartRow iStartCol iEndRow iEndCol iSheetIndex

To Know more about this VBA Help, download help from this link Microsoft Office 2003 Editions: Excel VBA Language Reference

If you are unable to run any VBScript, See my earlier post Unable to run VBS or CScript in Windows XP .

Accessing Excel - SilkTest

Few tools are providing built-in functions to read and write the data from Excel. Testers are comfortable with Excel than text file formats.

Silktest does not have any built-in functions to access data from Excel. But you can retrieve the data from Excel by treating Excel as Database. By using below code snippet, you can access the Excel data without pre-defined DSN. For this code snipper, You need to provide Excel filename with full path and worksheet name.

Silktest Excel - Code:

[+] public void ProcessExcelData(STRING sExcelFile, String sExcelSheet)
[ ] // Purpose: Drives test suite based on excel sheet(testcase) information.
[ ] //    Executes for given worksheet.  
[ ]  //SQL declaration
[ ] HANDLE hDB
[ ] HANDLE hSQL 
[ ] List of STRING glsData    //To get testdata
[ ]
[ ] Print ("Test data:{sExcelFile} & Worksheet: {sExcelSheet} ")
[ ]
[-] do
[ ] hDB = DB_Connect ("DRIVER=Microsoft Excel Driver (*.xls);DRIVERID=790;FIRSTROWHASNAMES=1;READONLY=FALSE;DBQ={sExcelFile}")
[ ]
[ ] //execute a SQL statement
[ ] hSQL = DB_ExecuteSQL (hDB, "SELECT * from [{sExcelSheet}$]")
[ ] //while there are still rows to retrieve
[-] while DB_FetchNext (hSQL, glsData)
[ ] GetListData (glsData) //Get all data without null
[ ]
[ ]
[ ] //clean up the query
[ ] DB_FinishSql (hSQL)
[ ]
[ ] //disconnect from the database
[ ] DB_Disconnect (hDB)
[ ]
[-] except
[ ] ExceptLog()
[ ] Print ("Excelsheet {sExcelFile} couldn't be accessed by SilkTest.")

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....

ON LOCAL ERROR GOTO Errhandler

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

 Exit Function
