.net - Set Mouse Pointer Location To The Selected Item In A Combo Box?
Feb 10, 2012
I have a combobox that drops up instead of down. I'm setting the selected item to the one on top of the list. I'd like to move my mouse pointer to point to it, so that the user that wants to click on that item doesn't have to move his mouse. I found how to move the pointer, it is with this command:
Windows.Forms.Cursor.Position = New System.Drawing.Point(x,y)
but I need to know how to get the location of the selected item in the combobox.
how do i program by saying if a certain item is selected in a combo box then that item will not appear in a second combo box. i have this code for now but it does not work

I ahve a combox (cbnames) on a login form which is populated with items. I make a selection and click on ok. Form1 appears and I have a textbox which I want to fill with the selected item from the combo box.
However, on form1 (view code) I don't appear to see cbnames. cbnames is available on the login form. How do i make a combobox public? or accessible to other forms?
I am having difficulty using the selected value of the combobox while calling it from the ok button click event procedure. While debugging in the Ok button coding none of the values are their, but for the comboxbox coding it appears that it is working properly.I made a seperate funciton to handle the combobox, could this be my error?

Visual Basic Express Edition 2008 Problem. I have a Combo Box containing Country Names "New York" & "New Zealand", when "New York" is selected it shows the time and date of New York in label1 on the form and the time is updated every second by the timer, but when I make another selection by selecting New Zealand in the combox dropdown list then New York's time updation is stopped in label 1 and only New Zealand's time is updated in label 2. Why the timer control stops functioning for the first selection after we make a second selection in the combo box. I want that time for both label 1 country as well as label 2 country updates simultaneously on the form. My code is as follows:I have added 2 label controls and one combo box control on the form and following code.[code]Can any one advice me how all countries selected in the combo box one after other are dispplayed with updated time every second?
I've been working on a GUI in WPF which I'm fairly new to, having only used Windows Forms up until now. So far, my GUI is very simple: it contains two rectangles, each of which drops a shadow. The shadow creates an effect of rectangles "floating above the canvas" so to speak.
When one of the rectangles is pressed, the myRectangle.MouseDown event is handled such that the shadow goes away, thus creating an effect of the rectangle being pressed down onto the canvas, like a button.Similarly, when mouse button is released, the myRectangle.MouseDown event is handled such that the shadow reappears and the rectangle "floats" again. This behavior make them resemble buttons. Note, there a reasons I want them to be rectangles and not custom buttons.
[Code]...
If the pointer leaves a rectangle while mouse button is pressed, I'd like shadow to reappear. This is arguable simple, because theoretically in this case, any time myRectangle.MouseLeave is raised, the shadow should come back on, even if it was already there.If the pointer left a rectangle when mouse button was pressed, then came back while before the button was released, I want the shadow to disappear again. This one is what gives me problems. No idea how to do this.
Now I can't use cmbReplcmnt.Text because what I actually need is the value of that SelectedItem
So problem is, if the user leaves the combobox as blank, it throws a null exception.I decided to use the IIf function then:classEquipmentItem.ReplacementTo = IIf(IsNothing(cmbReplcmnt.SelectedItem.ToString), classEquipmentItem.ReplacementTo = "", cmbReplcmnt.SelectedItem.ToString)
Unfortunately I still get the error I tried using a Try-Catch for it and it worked, but I don't want to rely on the Try-Catch, so I was wondering is there a another way to work this through?
VB.NET Winforms Application... When a user starts typing in the search box of the application it automatically populates the name list dropdown box with the valid results and sets the droppeddown value to true... Everything is working fine except the fact that the user is forced to select a value from the name list or press the esc key because without doing so the mouse cursor just disappears and you have to move the mouse all the way outside the application for it to come back and it will only do so while outside the applicaiton.. Below is the code that I am using for this and it should be noted that I am using the droppeddown value else where in the application and none of those instances have an issue its only this one..
Private Sub u_lastName_Box_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles u_lastName_Box.TextChanged u_nameLook_Box.Items.Clear()
I am creating a program that allows a user to view a list of foods in a combo box, add that food unto a list box, and adds all of the calories of that food together. When the user highlights their select food, the program automatically shows the amount of calories for that particular food in a text box. The program is getting the food and calorie information from an access database. I managed to get all of the food calories to add up properly, however, I ran into a problem. Sometimes, well, most of the time, when I select certain foods from the combo box, the program automatically reselects another random food, usually a food that begins with either an A, B, or C. Also, the other random food that the program chooses usually has the same amount of calories as the food I originally wanted to choose. I have over 6,000 items in the database. I don't understand why this is happening. This is what my code looks like for the button that adds each food to the list box:
Private Sub Button4_Click(sender As System.Object, e As System.EventArgs) Handles Button4.Click Foods_Selected.Items.Add(ComboBox1.Text)
Static i As Single
[CODE]...
And this is what my code looks like for the button that adds all of the foods together:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim x As Single Dim TotalCalories As Single
[CODE]...
I have no idea what to try. It's like the program just skips over random foods, even though all of the information for them is in the database.
How do I change my mouse cursor/icon to use a image or icon. I want to make a simple "wack a mole" type game but I dont know how to change the pointer to a icon or at least get a image to follow the pointer.
I am attempting to hide the mouse pointer when there has been a few seconds of inactivity and then re-show the pointer again when the user moves the mouse. I have been able to get the mouse pointer to hide and re-show as I require it, however when I execute grid.Children.Clear() and grid.Children.Add() the mouse pointer re-appears (but again hides after a few seconds of inactivity).
My code is as below: Private Sub Window1_MouseMoved(ByVal sender As Object, ByVal e As MouseEventArgs) Handles MyBase.MouseMove
i want to make a custom mouse cursor but I found that can be hard so I want to go the next best route. I want to see how you make an image follow the mouse pointer. I assume it would use some kind of image = mousepinter new point (x, y) or somethign like that. Suggestions or samples? In the end i want to take this code snippet and make a duck hunt game and a whack a mole type game
I have a problem in a vb.net windows application.I have a form with Sizable form border style. but i want to resize it only from TOP & BOTTOM. I have done the code for this.
But when i move the mouse on form's RIGHT & LEFT border, the mouse pointer gets changed to resize mode. When i drag it form size does not change. but when i try to resize it from LEFT whole form moved to LEFT. I do not need it.
I'm trying to move the mouse pointer to a certain position on the screen.I've done the declarations for both the SetCursorPos as well as the mouse_event, however I keep getting a Declaration expected error at this line: SetCursorPos(x,y),Perhaps something is wrong with the project or vb as well, cause I used an other declaration as well and when I wanted to use that I also got a Declaration expected error.[code]....
I have a program that has two list boxes. I want to have the user right click either listbox and remove an item using the context menu option. I have tried to use GetChildAtPoint (control.mouseposition) but I cannot return a control the mouse is over. I then tried to use the _Click event of the context menu to get the sender, but the sender is the contextmenu control. Here is the code I am using:
Dim ctrl As Control = Me.GetChildAtPoint(Control.MousePosition) If ctrl Is Nothing Then Exit Sub
I have a main form "Parent" and another "child" form. When I am filling a textbox in the child form the mouse pointer disappears. Then I hit the tab key to jump to a combobox. At this time when I move the mouse, the pointer doesn't come up until I click the mouse button. This is annoying and the user of my program doesn't like it. How can I keep the mouse pointer always on top. NOte: although the main form has the parent property as true, the other child form are not defined as child forms.
I want to make a small application for my web designing needs that will display the color of the current pixel under the mouse pointer. I need this to work on the entire screen (no matter what form/application is in focus) and it needs to update in real time.
I'm not worried about the math or working with coordinates, but I don't know (and can't find) anything that might get the color of the pixel under the cursor on any form. I've found a small number of VB6 examples, but I'm with .NET 2008. Does anyone know of a method or anything (DLL even >.<)
Pressing a Hotkey, I want to click the button of another application (a game table), knowing it x and y coordinates, without to move on the screen then mouse pointer, because this generate an annoyng fluttering.atm I use mouse_event, that works fine, but with the fluttering..In you opinion is this job is possible with a direct Api? I tried to hide the mouse with ShowCursor(False), but it works only over my forms, not over the screen...
I am using Vb.NET to build a windows application. In menu-strips by default the submenus will appear on clicking on the menu items. I am willing to display the submenu items by hovering the cursor on menu items. What is the procedure to do that?
Anyone know why the Mouse_Leave event fires when you don't leave the control with the mouse pointer?Put a large button on a Form so your mouse pointer does not leave it easily.Then try this codeWhen you do, leave the mouse pointer in the middle of the button and then click the button.By the way, if you uncomment the 1st line of code in the Button Click event and comment out the MessageBox, this does not happen.Can someone please explain this behaviour?

I am developing an application with multiple picture boxes, each displaying a line graph. I want to be able to have a label following the mousepointer showing xy coordinates of the point. I also want to allow a user to zoom in on a specific picture box by double clicking on it. The code does what I want as written (changes backcolor so I know double click event fires) except moving the position of the label to follow the mouse pointer.
However if if uncomment the line in the MouseMoved sub: LB.Location = New Point(e.X, e.Y) Then the label moves as desired however the double click event no longer fires.
Public Class Form1 Dim PB As New PictureBox, LB As New Label Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.Controls.Add(PB) With PB [Code] .....
