Disabling Button Before Executing VB Code To Prevent Duplicate Records?
Feb 15, 2012I need to disable a button after its pressed so the user does not have the ability to click it again as this would replicate the process in some cases.After alot of searching I found some tips - alot of code I found I could not understand.This is what I have come up with:
On page load:
If Me.Page.IsPostBack Then
'lblDetails.Text = "disabled"
[code]....
I also read somewhere that I should use: System.Threading.Thread.Sleep(1000) to delay the process or something - not entirely sure why I would do this though.Although, the problem with my above code is that when the code behind page performs validation checks, it exits sub before executing my INSERT SQL code - so when it does this it also disables the button.I am not entirely sure if the above method is fool proof or whether it is a **** piece of code that won't work 100% of the time.On another website I found a script to put on the actual HTML page with <script> tags:
Code:
<script type="text/javascript">
disableSubmit(frm) {

Testing For Duplicate Records
Aug 11, 2011I have a windows form application that connects to an access database. When the program is running it connects to the database and populates several textboxes that are bound to the dataset. I have been researching for 2 days and cannot find exactly what..I need, although a few threads have given me a better insight into my dataset. I would like to type text into a textbox that is bound to the primary key and when I tab out of the textbox (lostfocus event) have the program do a quick search of all records in the dataset of the primary key and if a duplicate exists, msgbox the user that that particular text is a duplicate and is not allowed, however if the text is not a duplicate, continue the tab keystroke allowing the cursor to move to the next textbox bound to the database.

View 3 RepliesDelete Duplicate Records From Combobox?
Apr 28, 2010I currently have a sql database linked to vb.net and I'm populating the comboboxes using SELECT statements. However, I'm getting duplicate records in the comboboxes.I have my database setup as 1 project to many submittals and 1 submittal to many items.
I have 3 projects in my sample dataset and I'll recieve 3 duplicate submittals and 3 duplicate items.
If I have 6 projects in my sample dataset than I'll get 6 duplicate submittals and 6 duplicate items.
I've tried adding distinct to my SQL statement, but that didn't do anything. Is there any reason why its showing as many duplicates as I have projects?

View 11 RepliesForms :: Prevent A Form From Being Minimized?
Sep 12, 2011I've got this little 'Sticky Notes' type of application and the form I have is a borderless, taskbarless form and for Windows 2000 compatability I'm using VS 2008 and targeting the 2.0 framework. One of the hurdles I have is that in XP, Vista & 7 when you click the Show Desktop button all of my note's windows get minimized and without a taskbar icon, it's not easy to get them back (at least not for a normal user) & I'm looking for a way to either right after the windows minimize I just have them all show again or if I can skip the minimizing message in the wndproc altogether that'd be great.
I've put together a test app that'll show the messages in a listbox for the form, but I'm not sure how to go about skipping sending the message to the form's base class. Here's a snippet, listMessages is the listbox on the form:
Private Const WmSize As Integer = 5
Private Const SizeRestored As Integer = 0
Private Const SizeMinimized As Integer = 1
