VS 2010 - Masked Textbox Cursor Start Position
Dec 23, 2011
I have created a maskedtextbox to do a simmple validation >L99999. My problem is when the user clicks on the empty box the cursor stays where they clicked it, not at the beginning of the box as it would with a normal textbox. I have found some suggestions but these all seem to affect the way the cursor moves within the box rather than just changing the start position. As far as the end user is concerned the box should behave just as any other textbox but with validation.

I have a MTB with the mask "00 / 00 / 00",
now when the user fills the mask, say he enters the value for the first two zeros(days part), after that i want the cursor to be automatically at the third zero. (yes the cursor automatically move when the user enters the next input, but i want it to move before the user enters the input)

Using VB 2010 Express
My program writes text to a multiline textbox. After the input is finished, the cursor is at the end of the text. I want the program to position the cursor at the start of the text so that I can see it.
MSDN suggests:-
tbPositionCursor.Select(0, 0)
I believe the cursor is now repositioned, but I cannot see the start of the text. How do I scroll back automatically, refresh or whatever so that I can see the start of the text?

I Would like to position the cursor in a text box using X,Y coordinates with X being the line number and Y being the column number. Is there any way to determine the line and column numbers of a textbox that is full of text. Using the .selectionstart paramenter only lets you position the cursor a certain distance from the beginning of text but there is no line information that I know of. By the way, I not an expert at VB so bear with me if these questions seem kind of basic.

I need to be able to take some co-ordinates from textbox and set them to the mouses position. I have tried a few things such as trying the 'new POINT' but i get the following error RDU.Form1.POINT has no constructors'What i am doing is sending the co-ordinates to a listener which then goes into a textbox and i want mouse to go to them co-ordintes.

I am working in VB 2008 and I have a textbox on a form that is used to enter a parcel number. I can enter the number in a 15 character string such as 12345678...... and it works just fine. The parcel number in real life contains dashes to make it easier to read, decipher, etc. so it looks like 12-3-45-67....... Under the textchanged subroutine for the textbox I have a case statement set up that checks the length of the parcel number as it is entered and inserts the dash accordingly.

I need the cursor to appear in my text box when the program is started so you don't have to click on the box to start the input. I have been trying tons of different things, including the .focus() command and "selstart" and no matter where I put them, they don't put the cursor there when the program is started. So I guess my question is what code do I use and where do I put it so that the cursor starts in the textbox for input.

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.

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

I've got a masked text box that throws an invalid cast exception if I try to put anything in the TextChanged event:
Private Sub mtbZVal_TextChanged(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MaskInputRejectedEventArgs) Handles mtbZVal.TextChanged
MsgBox("OK!")
End Sub
Even more oddly, it throws the exception in a completely different part of the program. The masked textbox is on a form that opens when you press a button, and that's the bit that gives the error:
Private Sub cmdAddLoc_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdAddLoc.Click
If frmLocation.ShowDialog() = DialogResult.OK Then
End If
End Sub

Trying to set the cursor position in a RichTextBox. The contents of a document are opened into the RichTextBox and I would like the cursor to move to the very start of the text.
At the moment, I'm using:
Me.tbLowerBody.SelectionStart = 0
Me.tbLowerBody.SelectionLength = 0
However, this seems to provoke my "Would you like to save changes" dialog on closing the RTB even though no actual changes have been made.

However the problem is that I am having problems displaying the form at my cursor position. I have a mdi chaild form in my app and when I right click I want to display my custom contextmenu form at the point where I right click in the mdichild form. The only other thing is that I want the middle of the form to be displayed at the cursor point.
