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'm currently working on an application that detects a color on a defined area on the screen and together with a panel that displays the color I show the values in a label and represent them with a vscrollbar. (The goal of the project is to output the color of the computer screen via an usb to dmx interface to create an ambilight effect) Now I don't want the user to be able to move the scrollbars up and down so I figured disabling them would do the trick but then the little square you click on to scroll it up and down isn't visible anymore.

If I have two buttons, one to start a song being played and one to stop it. The start button has enabled set to true and the stop button is enabled to false. What I want to happen is the stop button to only become active when the start button is pressed. I was thinking of putting stopMusicButton.enabled(True) within the start method, but this doesnt seem to work
View 2 RepliesI have a form with a button which is disabled by default, and a CheckedListBox with 68 items in it. What is the simplest way of enabling the button, when an item in the CheckedListBox is selected or unselected? I'm looking for something like If CheckedListBox1...any of the items state changes...Then Button1.Enabled = True
End If

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
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?
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?
ok I have an array and based on whether their is information in all the arrays nodes is dependent on whether a button is enabled.

I'm disabling a button in vb.net and when I do, I cannot control the BackColor or ForeColor properties to change the appearance. I set new values for them but they don't get picked up. The disabled button looks almost exactly like my enabled buttons so you can't tell the difference. I'm using Flat Style buttons, but have tried changing this and it still doesn't seem to work. Is there some sort of trick to be able to do this?

View 3 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

I would like to know how to make a button click only so many times until it becomes disabled.
I would also like to know how to keep what is put in a RichTextBox there, without erasing the other text;
Example: Two buttons, the first puts "1" into the RTB, and the second puts "2" into the RTB. However when I press the second button, it over writes the first value.
How can I prevent this?

View 1 RepliesI 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:

I'm using visual basic 2005 express edition I am having trouble with comboboxes and a button I want the button to be disabled "button1.enabled = false" when the program starts Then when the user selects a listing in all the comboboxes have the button become enabled "button1.enabled = true"
View 4 RepliesHow can i get the combo box to keep the value that was partialy keyed in and completed with auto complete.Pressing enter doesn't select the value so when you tab out it keeps the entered auto completed value. The only way to keep the auto complete value is to click on the combo box with the mouse and then tab out of it. I would like some how of being able to tab out of the combo box and it keep the auto completed value that the user has entered so as to save time entering data so no mouse clicks are needed and the data grid view can be tabbed through and all data entered from keyboard.
