Grouping many Messageboxes

Question

Hi I'm developing an application that uses an XML sheet with ID's. There are over 3000 ID's and when I start the application if some ID's aren't in the file that were there before.. I have error checking that makes a MessageBox popup that says ID: 12345 is not longer in DB except if there are many it is very annoying for the user to click OK or press the Enter key many times. How can I make somekind of check that would not display all those messages but rather just ONE message. (The message does not have to show all of the ID's just a general message of text indicating there was an error finding many ID's) Thanks in advance John

Wow what a convinient solution! Thanks Scott! Then logging the error ID's would be as easy as exporting them into a text file using a FileI/O object?

Just dump all of the errors into a stringbuilder and when you have the whole group either dump the list out into a messagebox or a custom dialog. StringBuilder sb = new StringBuilder (); // whatever test is collecting the failed id's for ( int i = 0; i { sb.Append( Error Message  + i + Environment .NewLine); } MessageBox .Show(sb.ToString() Error );
