I have done lots of searching but came up with nothing. How do I simply move an object on my form? For example, how would I change the position of a button when I press a button? I'm sorry if this topic has been beaten to death

View 2 RepliesI'm making a space invaders game and have simply used pictureboxes for all the aliens and the tank etc. This is really slow during gameplay so i'm hoping gdi+ will be faster. I've been researching how to do this for hours on end with no success. All I want to do is create a gdi object in the form of a bitmap or jpeg and for it to move across the screen smoothly at reasnoble speed.

how to make a collision between the player object and the wall which is a picturebox
i can move the player object (which is also a picture box) with the arrow keys and i've made it move inside the form border, but the porblem is how to make it stop when it touches the wall (picture box) if im moving left and the left border of the player touched the right border of the wall then it should stop and only the up, down and right keys will be working!!!
With vb.net code a Word document is manipulated. In this Word document there is a TextBox object that needs to be moved to a specific position in the document.I tried to start from a recorded macro in the Word document but I can't select the TextBox object while recording.
I tried to find a way using ActiveDocument.StoryRanges(WdStoryType.wdTextFrameStory) but I got stuck here.
Is there a way to move (the left upper corner of) the TextBox object to a specific position in the Word document?

View 4 RepliesI am working on a simple program which requires me to be able to select a picture box and move it to a new location by dragging it with my mouse. This is all the relevant code I have come up with currently. however, when I run the program it tries to move to where I want it to go then it seems to revert back to its previous location.

What is the best way to resize & move a form using just VB commands? I have a form that I need to set the Height and Top props, problem is that takes two calls and there is a noticable flicker. I tried using SuspendLayout/ResumeLayout, DoubleBuffered, swaping the top and height calls around, etc, but nothing seems to help. The test forms only have one small listview and one or two buttons.

View 2 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 have one form lays on the top of a form or a panel. I would like be able to drag the top form within the boundary of the bottom form or panel. How can I do that?
View 4 RepliesI'm having this problem with my code and cannot seem to get past it although it was working fine before. The error is "An error occurred creating the form. See Exception.InnerException for details. The error is: Object reference not set to an instance of an object." The code is:
CODE:
I am trying to get information to be pulled out of a database and show in text boxes on another form (frmviewsdets). The error occurs when it gets to the line frmviewsdets.txtsnumber.Text = rdr("StudentNumber") and even when a breakpoint is applied there it just moves on to the next and so on.
I have tried to show frmviewsdets before I pull the data out of the database beut I get the same message.
I have a solution with several Projects in it. There is a Windows App project (called ImportClient), and a Class Library (Import.Library). The Import.Library has functions to perform data imports (I have other applications in the solution that also need to call it). But the interactive application, I want to be able to pass in some form controls, and have it update the GUI. No problem. But, I also want to execute a DoEvents() so that the loop execution doesn't hang other interaction to the app.
So, ImportClient has a reference to Import.Library. But I can't add a reference to ImportClient to the Import.Library, because the compiler complains about circular reference, etc. I don't know how else to define the My.Application object of ImportClient as a parameter to the data function in ImportLibrary.
(I realize this is a dumb question - problem is, for this project I have a tight timeline, and haven't learned how to do the BackgroundWorker process. If you think I could pick it up quickly, I'm open to some hints about how to update the progress bar on the GUI, and how to pause / cancel the background task.)
I've got 3 forms that have exactly the same functions, so I decided to create an interface.
public Interface IExample
public sub Add()
Public sub Edit()
[code]....
At this point, objfrmExample is now instantiated, even though I've not done a "objfrmExpample = new [what-goes-here?] " and I'm curious as to why.I could possibly guess that because you cannot instantiate an interface variable, then vb.net automatically creates an instance. But thats just a guess. The question is , what is meant by declaring a variable of type Interface, and how does it work?
I am getting this error "Object reference not set to an instance of an object" and I dont know where/how to fix it and it does not tell me where the error in the code occurs, just a pop-up windows saying the error. Here is the code on the "start up" Windows form..

i want to be able to click anywhere there isn't a control on the form and be able to move the form to anywhere on the desktop...
the control box is off and the form text is blank, so there is nowhere on top of the form to click and move the form..
I was wandering if there is a way to move pictures around in a form and where ever you move them to, when you close program and open the program up they come up exactly where you lift them, And how can i add pictures to a form by say right click the form and select new picture and it adds it to the form, is there a way to do this, on how to do this or point me in the right direction.
View 1 RepliesHow do i load the Main form of a WPF so that a seperate thread goes and gets data from the database while the form is in an apartmentstate ? (drag-able / movable) I Know this is possible with opening a new window from your main form like this :
Private Sub openOrderWindow()
Dim OrderWindow As Orders = New Orders
OrderWindow.ShowDialog()
End Sub
[code]....
I've tried putting MyBase.ShowDialog() and .Show() and .9000+ other things The only benefit I've got out of using a seperate thread to load from the databse is i can see the screen right away (as oppose to it being a transparent box until it loads) but i cannot move it around or minimize itis there any way to make it Movable while it loads?

I wont lie to you, i havent really touched VB since I was about 16 (i'm 25 now) so I'm pretty lost on what the heck that means. I can get rid of the as any by changing ANY to LONG or INTEGER but I still cant figure out the speedo_frm part (that is the form name, go figure.
Edit: I'm using visual studio 2008..
I just started VB.NET coding, and I think I come along quiet well. Offcourse, I get a few errors, but When googling it, I always come to dream.In.Code, so I thought I'd better register here.
Now, my problem is, that when I set FormBorderStyle to None, it looks so cool, but I cant move my form around in debug mode (Nor when launching my finished builded application)
Here is my whole Code in my application, as I dont know what parts I should post here:
Public Class Form1
Private Sub Button8_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button8.Click
