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?
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?
A] Is there any way of stopping a user from entering text or changing text in a textbox without disabling it or
B] Is there a way of changing the texboxes back and fore color whilst it is disabled?
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.
View 20 RepliesI 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.
How do I disable a submit button until all controls are filled? Is there a way to do this without adding conditional statements to each controls?

In the project I am doing at the moment I want to disable the Exit ( X ) buttons in the top right corner of all my forms. So I found out this code which I�m using and is working fine:

I have 2 DatagridViewChecKboxColumn. What I want to happen is that a(Submit)button will be disabled until the checkbox2 will be checked. How will I do this if my checkboxes are DataGridViewCheckboxColumn? What loop will I do,because there's a possibility that I'll be checking the last checkbox?
I found this, but it's not working.
If (DataGridView1.Columns(e.ColumnIndex).Name = "Child") = True Then
btnConso.Enabled = True

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) {
[code].....
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.

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?

i've got buttons i'd like to highlight on mouseover. how does one change the image associated with a button?
i'd like to use the mouse enter and mouse leave events in order to change appearance of the button when the mouse is over it.
my environment: windows xp pro (sp3), visual studio 2008 pro, (sp1, sdk 1.1)
I have been trying for about a hour to get this to work but I cant. Want to do is change the location of my button when I check my Checkbox I tried If CheckBox7.Checked = True Then Button3.Location = (100, 277) End If is this wrong? It seems like it should work but it doesn't.
View 4 RepliesI'm making a simple text game over the summer for something to do and was wondering if it's possible to change a buttons OnClick functions on the fly?
For example, if they enter a door I want to change the buttons OnClick to call a different subroutine instead of the one that's already predefined in the code.
I have a form which has ONLY three buttons. Somehow they got named Button5, Button6, and Button7.
When I try to rename them Button1, Button2 and Button3 to match code, I get a Dialog box which, if I look at Details, says the Button name is already in use.
Is there something I can do to enable the renaming?
I made a code that will change the background button when the mouse cursor over it, the user press and release it ,and it work great.The code below is a part of the code I made, which will change the background of the button when click by user.
Method to use:
butclick(sender)
Sub butclick(ByVal butname)
'code reset of button background start
Main.bestassi_bluebut_about.BackgroundImage = My.Resources.buttonbg
[code]....
But I had to reset all of the background of the button first, the picture below explain why I need to do like this:
BEFORE ALL BUTTON CLICKED BY USER:
IF NOT RESET AND ALL BUTTON CLICKED BY USER:
IF WITH RESET:
So is there any better code for this? Because my method seen a bit silly. Is there any code that can change the background of all the button in one time?
Although my code compiles, it does not result in a change of the background picture of button1 here is my current code. Is it possible that my condition contains some error? or is the command itself wrong? [code]
View 1 RepliesI have a problem with my program. I have a form with 2 buttons UP and DOWN. I use this buttons to change the size of the form. The first step works fine. If I press the down button I get MsgBox ("Go Down", vbYesNo,) if I press Yes the form resize from 300 to 600 and if I press no it stay 300. The problem is, if the form is already at 600 everytime I press the down button I get the MsgBox ("Go Down", vbYesNo,) if I press Yes it recycles it self the form goes to 300 and then back to 600 and if I press No it stays 600. What I want is if the form is already 600 and I press the down button it skips the MsgBox ("Go Down", vbYesNo,) and the form stay at 600.
Public Class Form1
Private Sub ButtonUp_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonUp.Click
