Disabling macros while openning Excel files

My development required open and read Excel file with macros inside.
I’ve used my standard lib to open and read file-turned out that Excel macro displays dialog expecting user option selection.
What I’ve looked for was possibility to disabling Excel macros at all. 
I’ve googled a lot and finally found msoAutomationSecurityForceDisable as solution.


Example:

<br />Excel.Application excelObj = new Excel.Application ();<BR><br />excelObj.AutomationSecurity = Microsoft.Office.Core.MsoAutomationSecurity.msoAutomationSecurityForceDisable;<BR><br /><BR><br />// Create Workbook<BR><br />Excel.Workbook theWorkbook = excelObj.Workbooks.Open ( fileName, Type.Missing, true, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office<br />
