It sometimes returns true for composite numbers. oh and I know if you google it you get functions that do this, but most of them look inefficient so i'm trying to make my own.
I wanted to create a function that checks to see what button has been clicked on the windows form. For example If I had 10 generic buttons that open up different audio files. I would I create one Sub that can verify which button has been selected. I was either going to use a case statement or an if else. I did not want to create one sub for each button since it would be a lot of duplication in code.
View 2 RepliesSimple code! where am I going wrong. I get end of statement expected in line 4 after valid.
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If valid('0') Is True Then msgbox("HI")
End If

I have a class that needs to check for errors in the data contained in a object.The routines that will check for errors could be implemented in concrete interfaces of supertype IErrorCheck. That way error checks can be discrete and added or removed from the class that requests the error checks.Each IErrorCheck implementation would be programmed against the supertype IErrorCheck (Strategy).But it would be nice not to recompile when checks are added or removed.Is there an accepted procedure for abstracting the error checks all the way out of the program, such as to read the checks from a file?

Has anybody done it successfully without having to resort to pre-printed checks.
Can not resolve this. Two radio buttons data binded inside a group box.

He needs to put it on a private network and downloading exe files is not an option.
View 2 RepliesI am developing a hotel software product, and one of the features required is to be able to display the room numbers in the hotel, and then the status of them for each day of the month.
I am trying to create something similar to a DataGridView control where at the top the column names are the dates of the month, and to the left is the room numbers as rows. Please see the below screenshot of the function I wish to have. However I do not know what control or function they use to create this grid below (it is from an existing product). I need to not just be able to join multiple cells together when it is the same person in the room for multiple days, but also allow drag and drop ability.

I'm working on a WinForms solution in VB.NET. It's been a while since I'm mostly a web developper. So what I need to do is to replicate the behavior of Microsoft Office product for the Cut, Copy, Paste and Undo menus and toolbar. Which meens, I need to enable Cut and Copy when and only when there's some selected text on the Form. The Paste menu have to be enabled only when the is some text in the clipboard.
Do you have any ideay about how to accomplish that ? I probably would have to check some event in the TextBox's to check if some text is selected (MouseUp ?). Then in the Enter event, I would check if there's something in the Clipboard to enabled Paste menu..
I am developing an application which will keep track of various information about medical practitioners that are affiliated with my place of work. One thing that we are tracking, is their availability by time of day (morning, afternoon, and evening) for each day of the week (monday - sunday). Additionally we will store an optional comment about the practitioners availability, something like "Does not work during full moon."
The input/display form for this information will be table with days of the week as column headers, and times of the day as row headers. Check boxes will indicate whether the practitioner is available during the specified time.
I am having a hard time figuring out how to store this information in the database. The most obvious solution to create a table with 24 columns (21 for 7 days * 3 times, 1 as the primary key, and 1 for the foreign key referring to the practitioner, and 1 for the comment). Which is a crappy table, but at least it's easy to select and update.[code]....
