Asp.net - Disabling Button After Click
Nov 5, 2011
Private Function StoreCouponCode() As String
Dim con As New SqlConnection(ConfigurationManager.ConnectionStrings("DBConnectionString").ConnectionString)
[Code]....
When the user clicks on the CmdGetCoupon it takes some time to redirect..so the user clicks on the CmdGetCoupon more than once,which results in multiple coupon generation from a single user account.
I want to display a message "Please Wait While Your Coupon Is Being Generated" and disable the CmdGetCoupon so that the user cannot click multiple times

Take the following fundamental code:
Private Sub btnStop_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStop.Click
btnStop.Enabled = False
'Lengthy code procedure
btnStop.Enabled = True
End Sub
I've just notice that when I click on a button, and try to disable it in order to avoid the user clicking on it several times during process (or disable the entire form for that matter), the application somehow records the subsequent clicks and processes them after the button has been re-enabled. But that's not the behavior that I want at all. I just want to disable any user interaction with the button (or the form perhaps) until processing of the Button_Click event is completed. How can I do this?

I've used (buttonName).enabled = false to disable buttons when the user clicks on them but I don't like how the button becomes faded.
Is it possible to disable a button without changing the look of the button?

im wondering if it is possible at all to bisable a button after it being clicked because i have no idea on where to start on doing this. I only know how to get it to disable for the one session but when the program is run again it is enabled again. Is there any way to just keep it disabled because it nly ever needs to be clicked once.

I have a split container in my vb program that has 2 buttons right on top of each other in container 1. In container 2 I have a datagridview. The buttons are to mark a row as a blanket order that is in the DGV, so I'm only wanting the button enabled if the user is in the DGV. I was using another way of doing this by using the backgroundcolors of the rows like this :

I am trying to work on an application that disables the close button (X) on the upper right hand corner of a window. In order to do that I need to use calls to API methods like GetSystemMenu, EnableMenuItem and RemoveMenu. I can figure out how these methods work but there are certain parameters that these methods have whose values that need to be passed to them as argument is unknown to me. How can I know them.
E.G.- for EnableMenuItem, the parameters are- hMenu (handle to the menu), uIDEnableItem (The menu item to be enabled, disabled, or grayed), uEnable (This parameter must be a combination of at least two of the following:
MF_BYCOMMAND or MF_BYPOSITION
MF_ENABLED, MF_DISABLED, or MF_GRAYED)
Now when I call this method from my application I supply the current window handle as the first argument, the item no. to be disabled/enabled as the second argument but I CAN'T UNDERSTAND WHAT TO SEND AS THE THIRD ARGUMENT. What exactly are the possible values for those parameters- MF_BYCOMMAND or MF_DISABLED. I checked certain examples where they are supplying hexadecimal values like &HF060, &H1, 0x400, 0x1000, 0x2 etc. or integer values like 1024, 2 etc. But how would I know what exactly these values are and when to use which value. The same problem arises in case of calling RemoveMenu method. If you know about any chart or tutorial that lists the values of these parameters

im trying to disable a button until anything has been entered into two text boxes simultaneously.
So far i have tried:
If String.IsNullOrEmpty(TextBox1.Text & TextBox2.Text) Then
Button1.Enabled = False
Else
Button1.Enabled = True
End If
However it doesnt work simultaneously, the button will become enabled if i enter anything into either textbox, i cant have any of them left blank.

I 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) {

I was looking for quick assistance with disabling the write button based on wrong user input. Program works great just feel like it needs a little more.
[Code]...
I don't like validating through the TextChanged event either as I believe that to be the cause of some issues. Doesn't the Textchanged event validate on each time a letter is typed?

Using 2 forms how would I click one button, from another form? ie In VB 4,5,6, I would used to do it as:-
Form 1:
private sub Command1_Click()
msgbox "Say Hello"
End Sub[code].....
If I clicked the button in form2, it would automaticlly, click the button in form1. Do I, do it the same way in VB Express or has it changed?

I have a vb.net application that uses Flash movies (AxShockwaveFlashObjects.AxShockwaveFlash). I have buttons in the flash movie. When they first start using the application, they can single click on the buttons in the flash movie and button responds accordingly. But after a while (and I haven't been able to pin-point an exact thing that changes it or my issue would be solved), the user has to double-click on the button in the flash movie for them to work.

How can I make a program so you click a button and select a File using a OpenFileDialog and click send on your computer and it will send the file to a different computer and then a SaveFileDialog will show asking where to save the file on the other computer. Oh ya I cant use WinSock or whatever becuase im using Windows Vista 64 Bit. I need it because I for some reason cant use printer sharing. It might be because im on A 64bit Vista Machine and I want to print a file off of a 32bit XP Home Machine.

I want to create a server control that inherits System.Web.UI.WebControls.Button but gives it special capability, now what do i mean? i want my button to be a confiorm button that will work like so:
Renders to the page as a button of lets say cancel after the user clicks it i want to catch the click event (within the server control) and now after the click makeing the button not visible and makeing some kind of content placeholder (that will render from the server control) visible. that content place holder will have 2 buttons inside of it: yes and cancel. I want the programmer that adds this control to be able to register a function to the click event of the yes button. and the second cancel confirmation button should make the first button appear agian. (i know how to do this all in the client side but this time i need it all as server events)
My question is this: how do i catch the click event? i want it all to be handled inside the server control itself. so a programmer that adds this control wont have to worry about anything but just needs to register to the click event of the "yes" button.

1. Retrieving data from an .mdb
2. Displaying the table(s) in a datagridview
3. Populating an array of structures with the table data
4. Searching the array of structures for a member value equal to a string
5. Displaying the matching array elements in a listbox.
[code] Any suggestions? Am I missing something simple? Should I be using a Multidimensional array instead of a structure?

I have a basic window that has 20 buttons (One, Two,.....,Twenty).Currently if you click on a button its background color changes, and changes back on next click.I'm looking for a way to make it so when the mouse button is held down I can drag across the screen and it will change every button I hit.Disregard the "Shut Down", "Restart", "LogOff", "Clear", and "Invert" buttons. This idea doesn't apply to them.

We are having problems with the speed in parts of our application, Standard .NET 4 Windows forms application. We have a ListView containing some commerce items and the user can click on items to put them in a shopping cart. The problem is that when clicking 10 times fast on one item, only 4-6 items is added to the shopping cart.I get the same result when building a simple test application with only one ListView, with one item and a debug.print in the click handler.I have tried to add a Button in the same testapplication and this is fast..[code]

i just started playing with the menu toolbars in the toolbox. neat stuff. this thread is mostly for a contextmenustrip, since i'm trying to do a virtual right click on a regular click so the context menu shows..
i would like to know how to do a virtual right mouse click, so that's primary and reason for this thread, but if there is another way to have the context menu act on any other commands, then do post..

I have a button on my form where I'm showing a ContextMenu when the user left clicks on it, I'm actually using MouseUp right now to show it.What I would like to have happen is the user click on the button, the button stays pressed while the ContextMenu shows, it returns to normal when the ContextMenu closes (Either a menu item was selected, the user hits the escape key or they click/tab to somewhere else). Also I'd like to position the ContextMenu in the lower left corner if the menu opens down or the top left corner if it opens up. So the left edge of the ContextMenu is flush with the left edge of the button.Moreso the button staying pressed until the ContextMenu is closed.
Edit: I'm also ok with this being it's own control inheriting the FW's Button that used the assigned ContextMenu as well.
