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.
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.

View 1 RepliesHow would I leave the vertical scroll position as it is and set the horizontal scroll position all the way left if it isn't already in that position? I've been using Me.AutoScrollPosition and have come up with code that is satisfactory but I haven't been able to always leave the vertical scroll position exactly as it is and just move the horizontal scroll position to the left limit.

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.
I'm making some snippets and I want to position the cursor. I've come acros "$end$" but all examples I see are in c#. Since recently I've started programming in vb.net again and it seems $end$ isn't recognized or doesn't work here. Is there another keyword in vb to do the same?

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.

I have an ASP.NET form with multiple steps (using the Wizard control). When advancing to the next step, I want the page to start at the top, but for some reason it is maintaining the scroll position. I set the Page.MaintainScrollPositionOnPostback property to false, and I have the next button event handler set it to false also. I don't have the property set to true anywhere. But it is still maintaining the scroll position. What could be the issue here?
View 1 RepliesI was wondering if there is a way to keep the same scroll position in a datagrid view as the app jumps around to various rows (driven by the user selecting different timestamps or address). After the jump happens, the horizontal slider moves all the way to the right, but I want it at the same position as before the jump (or at lease go all the way to the left).
I have tried numerous things (datatable.AcceptChanges(), etc) but haven't been able to figure it out yet.
I'm looking for a simple, efficient way to get the position of the browser vertical scrollbar and save it into a session variable in an ASP page. What I'm trying to do is when the user changes a page I've the scroll position stored in a session variable so that when the user returns to the page the page will scroll to their last position.Is there a way to do this? I've seen examples of persisting the scroll position on postback but nothing yet doing exactly what I'm trying to do [code]
View 1 RepliesWe have a page which will diplay around 150 records at a time and for each record there is a link to input data. I want to be able to click that link on any record and have this one div with all the fields and updatepanel popup next to it.
I have found many JQuery examples of this, however none of the JQuery examples will allow me to Async-postback from the div which is very annoying. I also found examples where I place a div below each link and it pops up nicely, however this wont work because I need this to be only one div which contains the updatepanel and the associated inputs.
Do you know of a simple way to popup a div relative to the link? preferrably to the lower left of the onclick link/object.
I cant use the CSS left/top/right/bottom stuff becasue I need this to be relative to the object and not the entire page.
I am now using a datagridview that uses just 1 col and 1 row, but is set such that it has a large display width to display a lot of graphics.
The horizontal scroll bar is active to help me view all the data, but the scroll bar defaults to the LHS.
How can I make it default to the RHS?Additionally, when I move the scroll bar, the displayed data seems to get corrupted - do I have to re-paint the graphics every time the scroll bar position is changed?
What I am doing is I have an image in the webbrowser control that I am trying to capture and save to my computer but the image url is created dynamically and destroyed on the loading of the page (which keeps me from being able to use httpwebrequest to retrieve the image that corresponds to the page I am currently on). To get around this I am resizing my webbrowser control to the size of the image and taking a snapshot of the browser window itself.
The problem isn't with taking the snapshot... it's that when I take the snapshot it is snapping an image of the browser window prior to scrolling. I would like to figure out the scroll coordinates so I can basically write a function that will "pause" the routine and wait until the scrolling coordinates match that of where the image is located and then proceed to take the snapshot.
I have tried the .ScrollTop / .ScrollLeft values and .ScrollRectangle.Location.X/Y but I keep getting 0 as a return. Does anyone have any information on this? I've searched all over google but only find people asking the same question as me but recieving no answer.
i need to add an text at the end of the cursor position in vb .net .i tried
