"Enter parameter value" dialog box keep showing even I declare values on it.

25 Jul 2023 by Raf-Reyes

I'm new in VB.NET and I want to pass the value from vb.net to crystal report. I have a problem that the "Enter Parameter Value" keep asking a value even in my code there's already a value. When I remove this code I know "Enter Parameter Value"...

None of that code sets anything in report_Batch other than the two parameters. So at a guess, the command string (which we can't see) that the report is based on contains parameters you aren't setting. Use the debugger: find out exactly what...

"this" keyword in Extension methods

17 Sep 2013 by YourAverageCoder

Hi, my question is about "this" keyword's meaning in Extension methods. Here's an example from http://weblogs.asp.net/scottgu/archive/2007/03/13/new-orcas-language-feature-extension-methods.aspx[^]:public static class ScottGuExtensions{ public static bool IsValidEmailAddress(this...

"this" keyword in Extension methods

17 Sep 2013 by Zoltán Zörgő

It is a matter of syntax. The "this" keyword is only marking that you make an extension method for the type of that parameter. But I like this syntax because it is really in line with the keyword's other usage.

No, it won't mean the same thing, not even close. Every parameter counts and make the difference. Without "this" how would you access the object you want to operate on.You are confused quite well. Probably, all you need it to read on the topic more carefully:...
