Error when comparing larger

Post by diogogmaio » Fri Jul 01, 2016 2:10 pm

I am facing an major issue when comparing to excel files.
When the excel files are basic...few columns and rows...every comparison works.
When the files are huge like 2500 columns and rows i got the following error.

Code: Select all

/// <summary>
		/// method to compare two excel files
		/// </summary>
		/// <param name="refFile"></param>
		/// <param name="cmpFile"></param>
		public static void CompareExcelFiles(string refFile, string cmpFile)
			//validate path to configuration file
			//create CSV data connector
			string refConnector = "ExcelConnector";

			//create CSV data connector
			string cmpConnector = "ExcelConnector";

			//get data from ref. Excel
			Ranorex.Core.Data.ExcelDataConnector refExcelConnector = new Ranorex.Core.Data.ExcelDataConnector(refConnector,@refFile,"Book Value","",System.Windows.Forms.CheckState.Unchecked);
			Ranorex.Core.Data.ColumnCollection refExcelColumns = new Ranorex.Core.Data.ColumnCollection();
			Ranorex.Core.Data.RowCollection refExcelRows = new Ranorex.Core.Data.RowCollection(refExcelColumns);
			//load Excel connector
			refExcelConnector.LoadData(out refExcelColumns, out refExcelRows);

			//get data from cmp. Excel
			Ranorex.Core.Data.ExcelDataConnector cmpExcelConnector = new Ranorex.Core.Data.ExcelDataConnector(cmpConnector,@cmpFile,"Book Value","",System.Windows.Forms.CheckState.Unchecked);
			Ranorex.Core.Data.ColumnCollection cmpExcelColumns = new Ranorex.Core.Data.ColumnCollection();
			Ranorex.Core.Data.RowCollection cmpExcelRows = new Ranorex.Core.Data.RowCollection(cmpExcelColumns);
			//load Excel connector
			cmpExcelConnector.LoadData(out cmpExcelColumns, out cmpExcelRows);
How I am not able to retrieve the data from the Excel files? Is this because the files are too big? Or the format of the columns and rows?

Thanks for the help

Hi diogogmaio,

May I ask you why you are using the Ranorex Dataconnector to compare the excel files? As far as I know, the Ranorex Excelconnector is not intendet to compare two files. In my opinion it would be much easier using the .NET functionality as described in the following msdn post.

Well, that will be my fault ;) I've suggested using Ranorex data connector for simple csv/excel file comparison. I'm using it quite successfully with relative simple csv files. The advantage is that there is not required an additional csv/excel library and complex custom code. Just couple of loops ;) However, I agree with Robin that for proper comparison of large/complicated excel files, there should be used a dedicated solution. I'm not aware of any data connector limitation related to number of rows or columns. But Excel file with 2500 columns sounds quite crazy and not something I would ever consider to use ;)

I understand.

I have one more doubt. ... tNames.htm

I cannot put this to work in my code.

I want to load the file...then retrieve the worksheet names. How can I do this?
