The root cause for this issue is missing Super() method in DataSet.init() method.

Excel download and open error from portal

Once we download excel file from portal and try to open file the below error will be shown.

The code used for the download is as follows.
HttpContext.Current.Response.TransmitFile(filepath);
System.IO.File.Delete(filepath);
HttpContext.Current.Response.End();

Here the issue comes because the file will be deleted immediately once the file transmitted. During this time the original file will be locked by other process.

So changing the code as below will resolves the issue.

HttpContext.Current.Response.TransmitFile(filepath);
HttpContext.Current.Response.Flush();
System.IO.File.Delete(filepath);
HttpContext.Current.Response.End();

Error in Batch Job: Stack trace: Invalid attempt to call WinAPI.fileSize running in CIL on the client.

Batch Job end with error in Log as follows..

Stack trace: Invalid attempt to call WinAPI.fileSize running in CIL on the client.

The reason for this error is WINAPI in DocuActionArchive.add() method. Which will not work in batch job.

To solve this modify the method by using System.IO namespace classes as below..

fileInfo   = new System.IO.FileInfo(attachFileName);
fileSize = fileInfo.get_Length();

This will solve the issue and Batch will work without errors

A generic error occurred in gdi+ (C#.Net - while saving image to a file from image control)

Sol: Grant the write permissions to the folder. It will solve the issue
