View 7 RepliesLocking Multiple Sections Of Code With Same Lock?
May 30, 2011I have 3 web methods in a WCF, called 'DeleteGroup', 'AddGroup', 'ModifyGroup'.Each method has its own code. I want to place a lock on code within each method, so that only one method executes at a time. For example, if 'DeleteMethod' is being executed then no request for 'AddGroup' or 'ModifyGroup' can be executed. So may be I could use something like what is below, but not very sure ? Also, where in the WCF would I declare the locker object, and would it be private, public or static (i.e. shared)?
SyncLock locker
--Delete Method Body
End SyncLock

ASP.NET UpdatePanel Lock All TextBox Controls After Post-back?
Nov 2, 2010My code behind is VB.NET. I use ASP.NET UpdatePanel like the following. However, after the post-back, it locks TextBox controls , I cannot type anything, except when I move the mouse over and click on the TextBox.
why it locked all TextBox controls after the post-back?
Here's why I use UpdatePanel:
During the post-back, after inserting data into DB, set all TextBox text property to String.Empty After the form is submitted, the Panel pStudent should be refresh , not the entire page and the TextBox txtId should be in focus again.
here's the mark-up of the ASP.NET page: [URL]

View 1 RepliesHtml - Removing "Design-time-lock" Attribute From Legacy Code
Apr 4, 2011I'm converting a project from .net 1.1 to 3.5, and everywhere the following is used in the markup:
Design_Time_Lock: true
e.g.

I've read up about the Design_Time_Lock attribute, and I can see when it will and won't be generated. However I don't really understand the point of it. And- more importantly- can all instances of it be safely removed throughout the code?
Restricted Textbox Code (Specifically, Building A Class Library With Code)?
Jan 2, 2012I 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.

Asp.net - User Enters Code Into TextBox, Code Gets Added To URL (using Session)?
Sep 1, 2011I'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?
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim IB As String
IB = Session("IB")

Code When Leaving A TextBox?
Oct 6, 2010When 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 RepliesApply CODE Formatting To A TextBox?
May 28, 2010I'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.
