May be i can get some negative points on this question but, really this question is boggling in my mind from last many days that what is the basic/raw code behind textbox(or other such controls).i mean i understands that, we can inherit the textbox class and make our changes, we creates its object and use it.
View 3 RepliesI recently found this code (provided for third party use on another VB site), however,ll of my attempts to insert it into a class library have failed.I open a new class library and past the code in, and immediately get several errors pertaining to how certain objects can't be found. I find it it is crucial to use this code, unless someone can suggest to me another example of existing code that will do the same thing: make a restricted textbox who imputs can be restricted, that can handle pasting, shortcuts, text property setting, and script-entered text.

I'm using ASP.net 4.0 VB,I am using a session variable to add a user entered code into the url of each page. I can get the code to show up at the end of the page's URL that my textbox is on, but what do I add to every page to make sure that the session stays at the end of every URL that person visits during their session? This is the code from the page that the user enters their user code.
Protected Sub IBTextBoxButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles IBTextBoxButton.Click
Session("IB") = IBTextBox.Text
Dim IB As String = Session("IB")
End Sub

This is what I have in the page load of one of the other pages. What else do I add to make sure that variable is added to the URL of that page?

When a user leaves a TextBox on the form I execute a format and save to a variable. This is saved to a database by clicking on a ToolStrip button.
The problem occurs if the user moves the mouse directly from the TextBox to the Button. Neither the Leave event or the Lost Focus event is triggered, the variable is not created and, of course not saved.
If I put the code in the Save Button and the User moves to another control, the formatting(data type Double to currency format in the TextBox) that I want to show is not executed.

View 7 RepliesI'm playing with a simple string replacement editor for editing VB.Net functions outside of VB. Is there a way to apply VB.Net code formatting to a string?
For example. The txtboxCodeEntry looks like this:
If strVar="dummy" then 1 else 0 Endif
I would like it to "autoformat" to:
If strVar = "dummy" Then
1
Else
0
End If
The formatting would match whatever formatting VB.Net does when you're editing code in the Visual Studio IDE.
