How To Turn A String Into An Interger
May 11, 2011I am making a small guessing game, and I have a numerical number box in the option forms which sets the max number that can be generated. Because of the way I get the variable it wont update that value correctly. To fix this, I have a label which, upon closing the form, is set to the number of the numerical number box, and the max value is gotten from that label. My question is this: How can I convert a string to an integer? I tried one way, but got (i think, i cant remember exactly) a "First class expectation error" and something to do with "vbexpress.dll" (again, not the exact name) This then caused my Laptop to lag up so much that i couldn't do anything, and had to force crash it. So again, my question is this: How can I convert a string to an integer?

Jul 29, 2010Which options are there to make your 3-Tier System.Client / Common / Server Now we work with the entityframework and agatha. But are there other options to make a good 3-Tier system?
The agatha framework, makes for us the request/response on the common site. On the server site the response will be filled in. But are there other framework to do all that work for you? Or should you do it without such framework. And call at the server site stored procedure? Or with LINQ? With the agatha we query the repository's with some LINQ queries.
But i am wonna know if there are other ways to do the communication. Maybe there are other and better ways to do it. I hope i get some usefull answer. Where i can read some new things.

Check Value Change - Multiple Controls
Sep 29, 2010This sounds simple and I'm sure it is. I have a form with textboxes and combo boxes within a tabview that has 8 tabs. All the data is loaded from a database.

View 2 RepliesChange Check Box Status In Form While Other Code Is Running?
Jan 19, 2012I have a form which I use to read data from a text file and export it to an excel template file. The data it reads is constantly updated so I would like to add a check box to cause the data to be read every 10 seconds. It's set up so the user can either do one quick scan by clicking a button, or they can click the button while also having the check box checked and it will scan every 10 seconds.The problem is, once I check the check box, I can't uncheck it. I have created a greatly simplified version of my original code to demonstrate this concept.
