To prevent multiple clicks on button in VB6 I have add button.enabled=false in start procedure and button.enabled=true in end. But in Vb.Net all clicks are stored in memory and wher procedure is over - then it started again. You can see it in this example:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Button1.Enabled = False

I've messed with something such that I can no longer prevent the dialog from closing when the user clicks the Ok button but has entered invalid information.
Here is the handler for the OK button's click event:
Private Sub cmdOK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdOK.Click

I have an app where I need to dynamically choose an SQLDataSource for a GridView so I can use 1 of 2 stored procedures, depending on who is logged into the system. My problem is that I am using logic like this, in the button click...
If Session("SiteType") = "Type1" Then
GridView1.DataSourceID = "SqlDataSource2"
Else
[code]....
This happens when you click the button that reveals the panel with the gridview in it. The user then makes changes (basically adjusting a text box on one or more liens of the grid) and then clicks "save". However, the gridview no longer knows its DataSourceID once this happens, so when I try to go through the gridview's rows - there are none.
If, in the save button's click, I put the same code, it (of course) blanks out any of the data changes I made in the form. So, simply put - how do I dynamically choose the SqlDataSource, but only one time, so that the program then keeps that SqlDataSourceID associated with the gridview until the end of the cycle? Is this a ViewState thing? I don't totally understand ViewState...
I have been trying to figure out how to do this program for a few days. Here is the question.Write a Windows application that allows the user to enter a seven-letter combination corresponding to that number in a multiple line TextBox when the user clicks the Generate Words button.Avoid phone numbers with the digits 0&1.

Im creating a noughts and crosses game, what I want to happen is for the user to choose either an X or a O from a combo box then click the button to try and win the game, now the game is just about finished, ive finished the design work and all the code is written.HoweverThere is one problem, the buttons are not behaving correctly, when I first load the game the first two button select a character and they shouldnt until a character is selected, also when I choose a character only the first two buttons work, if I press the new game button which resets all the fields then everything works fine.Below is the code I wrote for my combo box - human player is a form level variable as a string data type

View 1 RepliesI am working on a Text editor. The problem I have come to, is that when a user clicks a button, I want all the text to be displayed on one line. The reason for this is I am having problems being able to upload CSV email files on a website I am working on, because the format isn't like email, email, email, email. Instead it is like
email,
email,
email,
So I have written a program that will format it. Only It still isn't working. I need it to recognise when there is a ".com," or something.
I have a form in which I draw a rectangle and a line depending on the button click. I basically want a dynamic line/ rectangle that moves when the mouse is clicked on another point on the picturebox. I found some code online for a rectangle, and I'm trying to extend it to draw a line too, but i'm having some issues. The line is not displayed when the mouse is lifted(mouse up event).
Here's my code:

Dim selection As Rectangle = Nothing
Dim m_Drawing As Boolean = False
Dim m_Start As Point
Dim square_click As Boolean = False

I'm running a survey to count how many times a user clicks the left mouse button. But the mouse click applies outside of the form, even applies to clicking start or other locations of the of the PC when the form has been minimized with a NotifyIcon. I know how to count the mouse clicks within a form but not outside the form. Somehow I feel I need to use a timer event but need it to apply outside the form. The timer tick event doesn't have a e.button event or mouse down event or mouse click for that matter. Whats a good way to get this function to apply outside the form?

1: counting button clicks and saving them to a variable and adding two. For example, if a button was clicked 10 times, the value of the variable would be 12.I would start with:Dim Buttoncount As IntegerButtoncount = ....This is the part i dont know. I would think it would be something like button1.click.numberofclicks or something, but i cant find anything that works
