.net - Winform: Cursor In Wrong Location On Backslash Or Delete

May 25, 2012

I set up a sort of filter on my textBox in WinForms, to exclude particular characters from being entered by the client.

a) Clicking BackSlash causes the cursor to move to the front of the string of characters, rather than remain at the correct position

b) Subsequent clicks of BACKSLASH still causes deletion from the correct location but the cursor remains at the beginning of the string

Private Sub txtExp_KeyPress(sender As System.Object, e As System.Windows.Forms.KeyPressEventArgs) Handles txtExp.KeyPress
Dim strtext As String = txtExp.Text

[Code]....

What I would like instead is to have the cursor in the correct location at all times.

Picturebox Cursor Coordinates Wrong In Win 7

Oct 25, 2010

With VB2008 I am working with a picturebox that I am capturing the pointer position on a mouseup event. I am using the following to get the mouse location

Private Sub PictureBox1_Click(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseUp
Dim mp As Point = PictureBox1.PointToClient(MousePosition)
'...
End Sub

This appeared to work fine until I tested it on a Windows 7 system. The mouse position it captures is wrong (is offset from the actual click). If you make multiple clicks, they are positioned correctly relatively to each other, but they are skewed away from the point(s) you are actually clicking. It�s like they are off a fixed amount. It works 100% in Win XP. Could it have something to do with the Aero theme on Win 7? Would this happen to be a known issue or result from a common coding mistake?

VS 2010 Changing Cursor - Format May Be Wrong

Nov 6, 2011

When I use the code
Public Class Form1
Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Integer) As Integer
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code] .....
I get an error saying that the cursor format may be wrong. It is a .cur which is the standard for cursors. How to rewrite this so when GetAsyncKeyState(1) then the computers cursor will change to the currentcursor.

Get Location Of Mouse Cursor Within Picturebox On Click?

Dec 25, 2009

I need to know how to get the position of the mouse within a picturebox just as you would with e.location, but you can't use e.location with a picturebox and you also can't use Picturebox.Mouseposition which is very unfortunate.

How To Change Cursor Position To PictureBox Location

Jun 30, 2011

I created a game where you use the mouse to play, it's like the game labirynth. You can't touch the walls or you lose. When I start the level I want the cursor to appear in it's starting position, which is a red picturebox.

Here is the code I used:
Windows.Forms.Cursor.Position = New Point(679, 650)
The location where the cursor appears is actually dependent of the resolution of the screen.

For example: with my monitor resolution, the location (679, 650) is right on top of the picturebox i need it to appear on. but if you have a different resolution on your monitor it will appear on a different place. I need to actually make it appear on top of the picturebox.

Control Added On The Fly Is Added To The Wrong Location Of An Auto-scroll Panel?

Jun 21, 2010

I have a program that adds controls on the fly to an auto-scroll panel. When the panel is scrolled (viewing the bottom of the panel for example) and a control is added, it looks like it is added assuming the top left corner of the panel is still at 0,0 when in fact it may be 0,500. To see what I am talking about, create an empty "Windows Forms Application" project and insert the below code into it.

Friend WithEvents Panel1 As System.Windows.Forms.Panel

Datagridview - Remove Wrong Columns And Display The Wrong Data

Jan 12, 2010

I've got a DataGridview I want to remove columns from as it greatly increases performance when I format the DGV. The first time I remove columns in a loop (using the removeat) property, everythings fine. But when I try to remove more columns in another loop, it appears to remove the wrong columns and displays the wrong data. In other words, it displays the wrong data and headers; and the columns it does show has headers and cells that don't match.

Replace Default Windows Cursor With A Custom Cursor (winforms)?

Feb 16, 2011

This VS010 solution is not providing my intended outcome as a custom override of a 'crosshair' or 'reticle' cursor e.Graphics.DrawPath() is the function that isn't working. This

WORKING solution demonstrates how it's supposed to work. The additonal PictureBox added to a Panel is, for reasons I don't understand, not allowing the 'new' cursor to appear.

Dim value As Point

value = instance.HotSpot But I don't know how to set the point value to (0,54) which is where I want the hotspot to be located.
