Draw Lines On Charts With Mouse Movements In Visual Basic 2010
Apr 13, 2011
I display a Chart with several graphic lines on it. What I want to do is draw a line (using the mouse) overtop or below the chart such that it can be seen on the chart. The mouse line draw code is below. What is required is either make
the line always be on top or make the chart transparent. I don't know how to do either and I don't know if it is possible in Visual Basic 2010 as it was in VB2.
Private Sub frmComDashBrdGraph_MouseDown(ByVal sender As System.Object, _
ByVal e As System.Windows.Forms.MouseEventArgs) Handles MyBase.MouseDown
If e.Button = Windows.Forms.MouseButtons.Left Then

I want to make an auto log off feature, I want to detect if there is any user input, and if there isn't the user will be automatically logged off. So I want to know how to detect mouse wheel events when the form doesn't have focus.

I have a Richtextbox and I would Like the user of the program to be able to drag and drog the richtextbox in other specified places in the program.
I have this very basic
Private blnLifting As Boolean = False
Private Sub richTextBox4_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles RichTextBox4.MouseDown
[Code]....
Firstly its very inaccurate. I want it so the Richtextbox moves with the mouse and not after the mouse. So I want a smooth drag and drog.
So I don't know if this is the wrong code for something that I want perfect like that.
Secondly I dont know if its possible but I would like it so the box can only be dropped in certain area's in my program and if there is a box already occupying that space, It goes back to where it was before.

I have few questions regarding the cursor movement. As you all know, moving the cursor is as easy as cursor.pos = new point etc... but that jumps your mouse to the new location. Anyway, here are my questions.
1.How to simulate mouse movements to look like humans'? I want my cursor not to jump around but move/ flow from point to point.
2. How do you click a point/place without moving your cursor? I know this is possible, just not sure how people do it. For example, say my mspaint. exe is minimized. I want to to random click at a coordinate in the mspaint.exe without actually having to move my original cursor.

I am working on mouse recorder and I got it where it will record and playback the mouse movement by using 2 simple listbox and some codes. But now I am stuck on how to get it to record the clicks and also playback that as well. I was wondering if I could just use another list box to store the clicks in it? But I am sure I got to do something more extreme.

I am trying to create an application that logs off a computer. I want it to check for mouse movement. If the mouse hasn't been moved in a certain amount of time then log off. I created an application for a form that if the mouse isn't moved in the form in 5 seconds the application closes. The reason I am trying to create this is because I work for the board of education and we have a problem with the teachers not logging off. The students get on there computers and mess stuff up. So my questions are:
1.) Is there a way to record mouse movements in windows instead of just the form? tutorials/info?
2.) Is there a way to execute a command like you would in a command prompt? For example if you type in shutdown -r it will restart the computer. tutorials/info?
3.) I do not want an interface for this just an icon in the task bar and for it to start on bootup. tutorials/info? When it reaches the time I want it to pop up with a form and say logging off in however many seconds and then logoff.

I've seen posts on deleting the lines from a text file that are specified as a function parameter, but I only need to delete the first and last lines from the file.
I'm still a newbie when it comes to working in files, but it seems that it should be simple to delete the first line... Just delete all text from BOF to the first CrLf character. Am I right?
As for the last line, I understand that I'll have to get a count of the lines in the text file to find it (as the file won't always be x amount of lines long).

I'm working on a custom scroll bar. When dragging the slider, things work smoothing with what I have... that is if the users movements are smooth and slow-ish. When moving quickly the mouse move event doesn't seem to fire as accurately as I had hoped.. I attempted using the up and down buttons enter event for re positioning or "resetting" the slider whenragging is activated but still those events don't even fire when the mouse move event is firing. So I believe I hit a barrier of my .Net knowledge and hope someone here knows a way around this little issue.

I have started to work some more on my 'shape editor'. If you're not familiar with it,ust imagine the Visual Studio form designer: a 'canvas' (the form) with a bunch of 'shapes' (the controls) that can be selected, moved, resized, etc. I have just finished implementing snapping between shapes and the canvas boundaries. But now I am having some slight issues with painting the snap lines.Just FYI: this is what I mean by snap lines:The blue lines that indicate that the 'buttons' are snapped to each other, and a purple line indicating that button1 is snapped to the boundary.
My shape editor is based loosely on jmcilhinney's 'manipulating GDI+ drawings' codebank entry, and a central idea in that post is to only draw what is necessary. In other words, when I move a shape I could re-draw the entire canvas, but it is much faster and smoother to only re-draw the old and the new location of the shape. Since nothing else has changed, I don't need to draw the rest. So, I simply invalidate the old bounds and the new bounds, and even with a lot of shapes all moving simultaneously it still feels very smooth.

Does anybody know which version of Visual Studio 2010 contains the full set of Visual Basic SharePoint Templates? I am about to embark on a project to create Visual Web Parts to be used in a SharePoint report.
At the moment I am using Visual Studio 2008 and even though the WSPBuilder is installed none of the relevant SharePoint templates are present.Having searched SO and the web, most advise to install the templates via the Visual Studio command prompt: devenv /installvstemplates
Alas the Visual Studio command prompt is also missing from my VS2008 installation.So, the question remains: which version of VS2010 contains what I need for pain-free SharePoint development? There is a rather large price different between VS2010 Professional and VS2010 Premium, so can anyone tell me if the cheaper version (VS2010 Professional) contains all the Sharepoint templates?

I am just wondering how I can add Direct X references to Visual Basic in Visual Studio 2010 Beta 2. I cant find them in the .NET reference list, or the reference list, or anywhere. I downloaded the Direct X SDK for August 2009, but I can not add the .dll files to the reference list. Is there anything I can do to add them? I need the references for programming reasons.

I m making a chart using MS Charts. Now the chart has mark points from where i want to get the coordinates if user clicks on the mark points.
I want interactivity in the chart such that on clicking on the mark points i can retrive the cordinates (x-axis and y-axis) for the mark points.
For example for the graph:-
on clicking on the orange dots or blue dots i want to get the cordinates for that point,
