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.
How to get the line number where the cursor is in a RichTextBox? I'm using VB 2010
View 2 RepliesI 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.
View 6 RepliesI am using a WPF richtextbox to create a syntax highlighter for code provided in a textbox. I want to have it automatically adjust the rich textbox as I am typing, using a thread timer I reset the contents of the rich textbox. I am trying to keep the cursor where it is suppose to be. I don't loose any text characters during the parse (except line breaks).
I don't know how to keep the caret position where the user has left it in the text. It defaults to the end of the document. I attempt to store the current caret position in the text and then set it to the document after I make my changes, however the error I receive is "Cannot set CaretPosition to be outside of RichTextBox." So I set the caret position to the bottom of the document.

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 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.
View 1 RepliesI am trying to use a windows form as a custom contextmenu which is fine as I have done a form with translucent background colour.

View 2 RepliesHow do I get the name of the (topmost?) control at the cursor position? The background: I implemented drag'n'drop from a dgv to a label and need to identify the control where the mouse button is released. I have enabled dropping on the label where the drop is going to take place. However, this label is the parent of say a hundred labels that are created dynamically in codebehind (I use this way to create a "dataview"). Therefore, I need to know which of these "child" labels the user drops the data onto.
I can get the mouseposition without problems (Me.PointToClient(Cursor.Position).ToString), but as I said, I can't get the name/text/ID of the control the user dropped the data on. Also, I ned to get the child control's name/ID/Text, not the parent label of course.In addition, it seems as if I can't select the row I click on in the dgv anymore, after I implemented the DoDragDrop on the CellMouseDown event. Any ideas? Should I use another event?

View 1 RepliesWould someone advise as to why the cursor position code does not work in the downloaded code snippet this code is from the second tutorial located within VB 2010. The debugger moves through the method but the cursor is not affected in any manner i.e does not move to position 10,10 when called to do so.I am using XP windows 2003 as a virtual machine through Macintosh OS X 10.5.8 -maybe this has an effect somehow?

View 2 RepliesI 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.
I want to insert a Link at cursor position in WebBrowser control.
