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.

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?

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.

I'm returning a database query into a List object and using that list object to fill the X and Y axes of my chart as seen below. (_runData is a "List(of DatabaseTableName)" style Object filled with the results of my query.
Primary_Chart.Series(0).Points.DataBindXY(_runData, "DateTime", _runData, "UPPER_PRESSURE")
My Datetime field is returning as a Serial Number (i.e. 40116.76111) so I want to format the X Axis to display the field more readably. Enter my problem code.

I have a ListView where ID and date is entered. The date is in the format dd/MM/yyyy.
In the SelectedIndexChanged Property I have written this
If lvRecruitmentList.SelectedItems.Count > 0 Then
txtID.Text = lvRecruitmentList.SelectedItems(0).Text
dtpRecievedOn.Text = lvRecruitmentList.SelectedItems(0).SubItems(1).Text
End If
In the dtpRecievedOn DateTimePicker, the Date is displayed like this

I am trying to change the cursor type to a crosshair but am having no luck. The program I am writing initially starts up as taskbar notfiy icon. Once one of the menu items is clicked the mouse cursor should change from an arrow to crosshair. This should remain like this when the mouse button is pressed again, held and then released and then it should go back to being an arrow cursor once again.To start off, I wrote the following code:
Private Sub changeMouseCursor(ByVal sender As System.Object, ByVal e As EventArgs) Handles DisectMyScreenToolStripMenuItem.MouseLeave
Cursor = Cursors.Cross
End Sub
This does not work but do not understand as to why this is. Visual basic 10 on Windows 7 SP1. dot net framework 4.5 Beta?

Using VB on a graphics screen I want to have the cursor move on a grid as opposed to every pixel. I believe I must hide the cursor and then draw it myself over the background, but I do not understand how to do this.

This is maybe an weird question because I don't know if its possible so prepare .I am working on a project its a kinda autoclicker.It moves the cursor to positions and perform mouseclicks it all works perfectly.So when it runs you can't do something else on the pc because the cursor gets moved every 1-5 seconds.So I wanna now if its possible to kinda attach it to the program I am making it for so it moves the cursor and do clicks within the form of the program.

I am working on a contract to repair problems in a application that interfaces with a custom built digitizer tablet.The application recognizes the tablet at startup, initiates calibration to locate the pad limits and then saves those limits to file.During the run of the application the user has a cursor that is changed to a line with a X on the left hand side of it. The user then uses this custom cursor to click in a PDF document where they would like the contents of the Digitizer pad to be placed. When they click a box signifying the size of the digitizer pad along with the same blank and X appears. What I have been having issue with is that the box and the line with the X appear most of the time but on occasion the line and X appears at either the top or bottom of the box and the click is no longer at the line with the X but somewhere in the middle of the box. This really screws up things and often the user has to uninstall and re-install the application to get it righted.
The values that save the calibration points are bound to variables during the build process, there is a separate routine to calibrate the digitizer pad if the user desires to do it again.

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.

I am currently reading a table from Access database and displaying it a DataGridView. Here is my
Dim ConnString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source= ....db1.mdb"
Dim SQLString As String = "SELECT Cost, Average, FROM expense_summary"
[Code]....
All the files in my access data base are numeric (database cannot be changed) but I need to change the value formats in the table. I want to convert one particular cell in the table to a percent with one decimal and also display the '%' symbol. Similarly, I want to round and display a '$' symbol in another cell. How would I do that? How would I select a specific cell in this table to change?

I have a datagridview populated using a csv file. I have a column named Date. The csv file has mixup of different date formats. So I need the date column in datagridview to be in standard "MM-dd-yyyy" format. I used below code
Me.dataGridView1.Columns("Date").DefaultCellStyle.Format = "d"It didnot have any impact.
So I used the below shown code Me.dataGridView1.Columns("Date").DefaultCellStyle.Format = "MM-dd-yyyy"Still no effect.

I created a new cursor (it works properly, I tried it in windows 7) but is not working for me in the program.I took the Windows cursor (aero_helpsel_xl, from C:WindowsCursors) and it appears to me the same error.i use with this code:
Me.Cursor = New Cursor("Patch..")
The problem say:: "{"Image format is not valid. Image file may be corrupted.
Parameter name: stream "}"
edit: I realized what the problem ... It can read only cur files with 24-bit color and lower - but it shows only two colors: black and white.

Bit of a strange question but I have a refresh button which clears my screen but after clearing the screen the textbox2 get selected (even though its readonly) so would it be possible for no control to get selected or textbox1 to get selected after i have hit refresh?

my code is as below.
vb
Dim RegKey As RegistryKey = Registry.LocalMachine RegKey = RegKey.OpenSubKey("SOFTWAREMicrosoftWindowsCurrentVersionAuthenticationLogonUIBackground", True) RegKey.SetValue("OEMBackground", "00000000") RegKey.Close()
If I output the contents of it on a msgbox, things are fine, but when I go to regedit, the change doesn't happen where it should as it actually happens in another registry key located at
HKEY_LOCAL_MACHINESOFTWAREWow6432NodeMicrosoftWindowsCurrentVersionAuthenticationLogonUIBac
k ground which I guess happens since I am on windows 7 64 bit, but I don't want that to happen as doing that doesn't change anything. The key I'm trying to change makes changing the default logon screen possible in Win7, but it's not working like this since the wrong key is being modified.

Problem:I am not getting the cursor (4 arrowheads) for moving the form.I am using the Panel1_MouseHover to display the cursor. Right now if I choose any other cursor then it is working but the same cursor also displays when I hover the mouse over any other control. I want the cursor to show only in the areas of the Panel where there are no controls.How do I show Tooltips for the images? The play,stop,next, previous,playlist,Hideme(with the smiley),volume are all images and not buttons?

I am trying to read a file and note the last position in the file. The next time I look at it, I want to pick up where I left off. What I'm finding is that sometimes when it comes back to the file it is 2 characters further in than it should be. The code I am using is:
Private Sub Read_Log(ByVal skip As Boolean, ByVal recursive As Boolean)
Dim logfilestream As FileStream
Dim logreader As StreamReader
[Code]....
I'm thinking about backing up to check previous characters - but I'd rather not hack over the problem if there is an actual fix to it.

I'm trying to set a new cursor position but I get this error:
A call to PInvoke function 'mon! WindowsApplication1.Form1::SetCursorPos' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.
Here is the code:
Declare Function SetCursorPos Lib "user32" _
(ByVal x As Long, ByVal y As Long) As Long
SetCursorPos(457, 603)
It used to work when I used VS 08 but now I use VS 10 and this problem has started to appear.

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 know how to get the cursor position but how do I add a character to that position. Like I want to have a button that adds a specific character at the position of the cursor.
I don't see any richtextbox properties that allow me to add anything at the cursor position.
If TypeOf Me.ActiveControl Is RichTextBox Then
Me.ActiveControl.SelectedText = Chr(176)
End If
