[Code]...
I Ported this code from a code project article in c# called Nscript
heres the code
Base App
Imports System
Imports System.IO
Imports System.Resources
[code]....
Okay Now I only get two errors (I dont know how to solve them)
Error3Class 'BaseApp' must implement 'Sub OnCompilerError(errors() As CompilerError)' for interface 'IScriptManagerCallback'.
And
Error4Class 'ScriptManager' must implement 'Sub CompileAndExecuteFile(file As String, args() As String, callback As IScriptManagerCallback)' for interface 'IScriptManager'.
But What I would also Like to know (as well as how to fix the errors), is would the code work?
I have an web application of 200 web pages and all has a single master page. Most of the content pages use AJAX controls so most of content pages has its own ScriptManager. Now I have a requirement to add a link with HoverMenuExtender control and for that I need to put ScriptManager in the Master page, but it is working only in the content pages where there is not ScriptManager.
View 1 RepliesDoes vb 2010 have a 'REQUIRED" property or control that allow you to make a textbox a "required" field? I googled and saw something about required property in controls in toolbox but somehow I could not find it anywhere in my vb 2010 toolbox. Would it be easier to write it? Does anyone have sample code?

Dim samples() As Single
If samples(i) = Nothing Then
samples(i) = _mPreviousSamples(i)

View 5 RepliesI'm an avid programmer, and I'm trying to teach myself more professional practices, but Ilook over my code, and point out any mistakes, or bad practices I may have attached to this actually working bit of code. It consists of a procedure for retrieving, sending, and above all connecting to a server program. As for the various amounts of sloppy commented out code, after a long time clearing my head, I came to my senses so to speak.

I want to automatically generate a reference number that is not already present in this database, to do this i know i am going to need to search the database to check whether that number is already present or not.

View 8 RepliesI've been getting the following error from time to time and have been unable to determine the cause of it:"The given key was not present in the dictionary."The line that this is occurring on is:If CType(ViewState("FieldType"), MYClass.FieldType) = MYClass.FieldType.ShowOnDirectory ThenI have no idea as to why it is throwing this exception on this line. I thought that perhaps an invalid value was being placed in the ViewState so I tried while debugging setting the value to Nothing and setting it to a value that wasn't in the enumeration and it still works. I was originally storing the enumeration in ViewState and then went to storing just the Integer equivalent in there

View 1 RepliesI've started building a small game where you move around a PictureBox control with keystrokes using the arrow keys. Everything was working fine....until I added a button.
Now the button steals the focus so that every time I hit an arrow key hoping to move my image, it just selects the button.
Is there any way to make the button selectable only by mouse click?

View 1 RepliesI am using the following code to bring up the keyboard map in an application:
System.Diagnostics.Process.GetProcessesByName("Filename.exe")
System.Diagnostics.Process.Start("osk")
It works great, but I also have three radio buttons that change the language at the application level only, and when I click one, the language on the keyboard map should update, but does not. The only time it updates is when the mouse is over the keyboard map. Is there a way to detect if the keyboard map is shown, so I can make it update to the new language?
You cannot just make a variable like:keyboardMapPresent = True - because you have to also be able to detect when the keyboard map is closed!
