I am creating a custom Label control (by simply Inheriting the standard Label control and re-painting the background and text) because I need a very specific background and border. In the constructor of the control, I set the AutoSize property to false so I can have a standard default size for the new label. Public Sub New() /*Se...

The one cell has a columnspan of 7 so it runs across the entire gridview. how do i align that label programmatically?? Dim cell As New TableCell Dim lblfilter ...
If I have a string like: "26 things" I want to convert it to 26. I just want the integer at the beginning of the string. If I was using C, I'd just use the atoi function. But I can't seem to find anything equivalent in .NET. What's the easiest way to grab the integer from the beginning of a string? Edit: I'm sorry I was ambiguous...
This has been a pet peeve of mine since I started using .NET but I was curious in case I was missing something. My code snippet won't compile (please forgive the forced nature of the sample) because (according to the compiler) a return statement is missing: public enum Decision { Yes, No} public class Test { public stri...

With typed-datasets you load many tables from one sproc and then simply use statements like: //get student’s course StudentsDS.Course drCourse = drStudent.CoursesRowParent; // get course students foreach (StudentsDS.StudentRow dr in d...

I have a form with a list that shows information from a database. I want the list to update in real time (or almost real time) every time something changes in the database. These are the three ways I can think of to accomplish this: Set up a timer on the client to check every few seconds: I know how to do this now, but it would involve...
Imagine an in-house application aimed at the very technical user. The app maintains data. There isn't a heck of a load of data, but there is enough to make some sort of a query mechanism necessary. The application's UI is very simple. It basically allows the user to enter a query (as text), and shows the data matching that query. Had t...

I have a class that currently has several methods that take integer parameters. These integers map to operations that the application can perform. I'd like to make the class generic so that the consumers of the class can provide an enum type that they have with all the operations in it, then the methods will take parameters of that enum ...
This question about Timers for windows services got me thinking: Say I have (and I do) a windows service thats waiting on a WaitHandle and when woken, it dives into a wait-spin like I have shown below in a flowchart I'm curious if using a timer would be better than a wait-spin loop (sometimes called a spin-wait). I'll be honest, I'v...
I am doing an archive service for logs. Since some files are open and in use I can't archive them until they are not in use anymore. The only way I can figure out how to see if the file is open by another process is the code below. I hate the code there must be a better way. Is there a better way? try { using (FileStream stream ...
I've got an issue with nested controls not loading properly. I've tried various page methods and nothing seems to work. EDIT: The site compiles and runs fine--it just leaves a blank screen though.
