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.
how do i insert text for the designated object when the help button (next to the 'close' button) is pressed?

View 3 RepliesHow would I check if a key is currently being pressed?
Also how would I detect if a key is pressed without using the KeyDown event. The reason I am not using the keydown event is when the user holds down a key it calls the event, waits a second than keeps calling it. I do not want the wait period if a user is holding down a key.
I have button1 and button2.When button1 is pressed, I want the color of button2 to switch between white and red every second until it is pressed.

I have a button on a form, and I want to increment a counter an display it in a lable, while the buttion is pressed. Similiar to a numberic up down control. The reason is that I want to use a custom looking button, rather than the look of the numeric up down control.
Is there an easy way to do that while the button is being pressed? Or would it make sense to change the look of the numberic up down (I don't want UP and DOWN on the same control, though).
When I press a button on my form i need it to open a file. E.g. I want it to open a song (in windows media player, windows media player is the default program to open mp3's)

When trying the above ^ it just says file cannot be found.
I'm developing a interface in VB.net which will control two stepper motors. Counting on your tips I managed to control them manually I mean, there're 4 buttons used to move the motors clockwise and anti-clockwise. The point is, the main part of our project is control the motors automatically. Our idea is based on two editable fields, X and Y, where the user would insert the displacement value he'd like the motor to move. After filling up both fields, the "GO" buttons would be pressed. So the loop would run depending on the displacement values in X and Y.
Attached you can find the main screen:
Below you can find the main code.
Public Class Form3
Dim velocidade As Double = 0.004
Dim X As Integer = 0

Im 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.
My little chunk of code is below:
CODE:
On an form i have few labels, upon clicking on that labels i want to display an another form which contains 3 textboxes(Default,Current,New) and 3 buttons(Default,Current,new). I need to save the values of all the textboxes to the label's tag, but the label's text will contain the value of the textbox based upon the button which is pressed. i.e if 'Default' button is pressed then the 'Default' textbox text should be the label's text. I have created a class with three mem. variables to the save these class objects in the labels tag. But how should i know which button was pressed.
