.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.

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?

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.

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.

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.

The code bellow should perform a mouse click at the location the cursor is pointed, however it only activates the control from that location.

Declare Auto Function sendclick Lib "user32.dll" Alias "SendInput"_
(ByVal nCommands As Long, ByVal iCommand As MOUSECOMMAND, _
ByVal cSize As Long) As Long

I am using this line of code to place a special character in a textbox at the cursor location:
Me.RichTextBoxPrintCtrl0.Text = Me.RichTextBox.Text.Insert(cursorloc, "ῳ")
It works good, but after it has been done, if you try to undo the action by pressing control Z, for example, it is not undoable. Is there a way to make the action undoable?

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
Friend WithEvents btnAdd As System.Windows.Forms.Button
Dim ButtonCount As Integer

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.

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.

I have a user control, and want to be able to update its cursor while it is disabled. For example, say that I have a user control whose cursor is Default. The below code works ONLY when the user control is already enabled; if it is disabled the below code doesn't work and the cursor remains Default: Me.MY_USER_CONTROL.Cursor = System.Windows.Forms.Cursors.WaitCursor

I have a custom cursor that I have as a ico file as cur files are only mono coloured and 32x32.
The only problem in using a ico file is that I can't set where the hot spot is and at the moment it is set in the middle of the icon which is no help
I was looking on the msdn website and it said to set the hotspot like this
Dim instance As Cursor
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.
