I'm working on a project which has 4 combo boxes.Each of them has a drop down list of numbers from 0 to 9.
How do I validate if each combo box is selected with one number when I click on a button?
Is validating a checkbox the same way as validating combo box?
On each of my form I have put an 'Exit' button. When user clicks it, another form is displayed (I don't want to use 'MessageBox') asking user whether he really wants to quit. If user clicks yes the form closes. If user clicks no, form is redisplayed.
However, out of 4 forms only one form refuses to redisplay. The code is exactly same on all forms. I have included 2 Express 2008 projects showing one form each in the zip file apps-ssk.zip

I add a button to a form each time the user clicks a menu option as:
[Code]....
This draws a small blue line at the bottom of the button to show it is highlighted. Just like the mouseoverbackcolor property on a button except this will draw the line. It works fine until you slide the mouse very fast between the buttons. It is as if the mouseleave event doesnt always fire.
I basically, want this to happen:
Label1.Text = Form2.Button1."number of clicks"
How do I do it?

View 2 RepliesIm looking for guidance/example on how to track if a button was pressed so that I can turn on another button and turn off the first button. I am saving a bunch of user data to a text file & that works fine. Once the user enters all of the required data, I turn on button "btnCBSave". What I am trying to accomplish is once button "btnCBSave" has been pressed once, turn itself off and make button "btnCBNew" visable so that the user can enter new data.

I want to be able to hit enter or return on the keyboard and then for the next button to automatically click. Once you're done typing in the value to a textbox you hit return and the next button clicks.
View 3 RepliesTo 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:

Button1.Enabled = False

View 3 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,

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?
