View 1 RepliesEarlier I was working on a project, and I added a StatusToolStrip and the the ToolStrip I added a label and a progress bar. The label will say the current sub or function that is in progress and the progress bar will show how far along it is through the sub or function. I have tried this myself but I cannot figure it out as I rarely use progress bars.
An example of a code that I would like the progress bar to show would be like this:
Private Sub StopServer_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles StopServer.Click
'Checks to give server notice
If My.Settings.warningmessages = True Then
Dim cmd As String = My.Settings.warningmessagetext(2)
[Code] .....
So while the sub is running the label would say "Stopping Server" and the progress bar would show how far along the sub is.

i want to make a custom mouse cursor but I found that can be hard so I want to go the next best route. I want to see how you make an image follow the mouse pointer. I assume it would use some kind of image = mousepinter new point (x, y) or somethign like that. Suggestions or samples? In the end i want to take this code snippet and make a duck hunt game and a whack a mole type game

In VB.Net with Winforms how do I make an image follow the cursor even when it leaves the form? I want to do this during a drag and drop operation. BCL and/or GDI is better for my usecase than P/Invokes.
If you are familiar with PeaZip, it does something of this sort when dragging a file from it's interface.

In a game i am making, as the mouse cursor i have crosshairs (like those in FPS games) and i would like an image box to change images as the mouse moves so that it appears that the character in the picturebox is following the mouse cursor.
i thought i would do something along the lines of first finding out which side of the picture box its on (left or right) then finding out exactly where with some maths equations and then assigning 1 of 60 pictures so that it appears that the picture is rotating.
I�m trying to implement a licensing schema for a template that uses the follow code snippet. (using VS2010 vb.net4)

I need to utilize the GUID value in other classes within my application, as an example, as making registry entries.My goal is to have this editable at only 1 place in the template.I�ve created a Friend class that has the GUID string in it, but I�m unable to get the above to recognize the string. I�m sure that the code is simple, but it evades me.I would really like to do is to access the Guid that VS2010 vb.net creates (Project->Application->Assembly) shows and insert it into my application.
I'm working with a project that is WPF and VB.net. I want to visually simulate "dragging" an object (though I do not want to use standard drag and drop for reason of purpose).Basically, I have a label object that, on its MouseDown event, I want it to follow the mouse cursor inside a 640x480 solid-size grid (but not outside of it!). Mind you, this grid is centered inside a full-screen window. Again, the object should not follow the mouse outside of the grid (I'm guessing a "ClipToBounds = True" here)Then, on the label's MouseUp event, I want it to either stay in its current position or return to its original position, as determined by the value of a boolean variable set by another object's MouseEnter property.Note, if it would be easier to work with, I can change the grid to a canvas in a cinch. I'm guessing that would be desirable.
How do I make the object (label) follow the mouse cursor inside the grid/canvas, but not outside of it? This needs to happen on the MouseDown event of the label.How do I make the object "stick" in its current position? (From this, I can probably figure out how to make it return to its original position on my own.
I have pretty large file names that follow a standard naming practice and I am attempting to write a RegEx to match them. When you are reading the file name it follows the convention:
p_d(set of 8 numeric)_t(set of 8numeric)images.ext(any# of alphanumeric)
For example:
p_d12345678_t12345678_images.ext_0
The few I attempted brought back unrecognized escape sequence OR no matches found. For example this one brings back no matches:
fileInfo = value
'that changes depending on what file I'm looking for
RegEx("p_dd*_t" & fileInfo & "d*_images\.ext_w*")

View 5 RepliesI've come across a very basic problem which I'm sure has a basic answer.Forgive me but I haven't programmed in years and this just a hobby of mine..My problem is that I need a drawn object (say an ellipse) to move to the cursors location when I click. Imagine an adventure quest style game where you view your character in birds eye view, and it moves according to where you click on the map.I can draw the image fine, and move the image around fine - it's more so the formula I'm using which I'm a little stumped on.I have certain requirements though.
1. I need a timer that constantly updates the drawn object's (lets say character from now on) location. Each tick will essentially be the character taking 1 step towards the cursor's location.2. At the end of each tick of the timer, it'll will invalidate the form/control to invoke the paint event, and of course, the objects location will be be updated.It sounded simple enough to create a linear equation based on the objects original location and the location of the cursor when I click.However, that will not give it a fixed speed.If say for example, the gradient (rise/run) between the cursor location and objects location is very steep, the object's y-velocity will be greater than that of the x-velocity
I am developing an application with multiple picture boxes, each displaying a line graph. I want to be able to have a label following the mousepointer showing xy coordinates of the point. I also want to allow a user to zoom in on a specific picture box by double clicking on it. The code does what I want as written (changes backcolor so I know double click event fires) except moving the position of the label to follow the mouse pointer.
However if if uncomment the line in the MouseMoved sub:
LB.Location = New Point(e.X, e.Y)
Then the label moves as desired however the double click event no longer fires.

I have a form with 4 comboboxes and a button. The first combobox is enabled, but the rest of the controls are disabled. When the form is opened I fill the first combobox (cbxMethod) with a datatable. When the user selects something in cbxMethod the next combobox (cbxStudy) will be filled and so on. When the last combobox (cbxAnalyte) has a selected value I want to enable the button and give it focus so the user can move forward with the program. I basically want to force the user to move from one combobox to the other, until all are filled.I am currently using the SelectionValueChange event, but this event only fires when the user changes the value with their mouse or hits the Enter key, not when the user hits the Tab key.
