I'm building a Visual Basic program to allow me to change my desktop background through VB. I've made it so the user can select a file and set it as the wallpaper but i'm wondering if there is a way to allow the user to decided on the position eg Stretch, tiled or centre.
View 1 RepliesI am having in VB.NET 2010. I am writing an app to change the background wallpaper kinda a little project I am making for my wife's grandma. It is a multiple wallpaper changer to change the wallpaper based on a list of images she adds. Anyways! I have everything setup except the fact that it doesn't change the wallpaper...
This code here:
Public Declare Auto Function SystemParametersInfo Lib "user32.dll" (ByVal uAction As Integer, _
ByVal uParam As Integer, _
ByVal lpvParam As String, _
[CODE]...
Will NOT change the wallpaper but the same code works in VB6 I tried it because I have made something like it before in VB6 but it was a game that changed the wallpaper. Anyways, using the above code in VB6 works(well with a change to the SystemParametersInfo declare to work within VB6. But it doesn't work in VB.NET. I have NO IDEA why everything gets set in the registry just fine from VB.NET but I just cannot seem to get it to update the wallpaper...

Below is a short section of code from an application I am working on. What I am trying to do is to get a counter value to show when the application is minimized. When restored back to normal state, the name string is applied. It works, but it takes several minutes to change, and then never updates again. Not sure what the issue is.

I also tried a direct string conversion in the "elseif" part. No difference.

View 3 Replieshere a simple class to change the wallpaper in winxp and win7. i think it will work on every windows version.
[Code]...
I thought this would be easy but for some reason it's giving me a rough time. I have a windows form with three equal size panels on it. Each panel takes up about 1/3 of the window width, less some inter-panel spacing.
The effect I want is if the user stretches or shrinks the form the panels maintain their relative 1/3 width and spacing, similar to how divs on an html page would size as the browser window is sized.
So I anchored the left panel to left, top and bottom, the center panel to top and bottom, and the right panel to top, bottom and right. This works fine in keeping the left and right panel anchored to their respective sides, and all panels now stretch with a form height change.
So in form resize I adjust the width of each panel to form.width/3. As expected this is close but does not account for the inter-panel margins I want to preserve and the form border width.
I played around with various constants and noting I do gives me the desired effect.I'm sure there is a pretty straight forward solution to this but I can't seem to find it.
I have a class that contains one function: "ShowDialog()" It creates a new openfiledialog and sets its title, but when it is run, the title of the openfiledialog is set to the current directory that is shown in the dialog. I would not like this behavior. Here is the code:
Public Class LoadSet
Public Shared Function ShowDialog() As System.Windows.Forms.DialogResult
Dim Dialog As New System.Windows.Forms.OpenFileDialog
Dialog.DefaultExt = ".bsfci"

I have a panel, 80 pixels wide and 720 pixels high. However, this panel will stretch to whatever height the user's display is at as the form border style is none and the form is set to maximise.
Inside the panel I have another panel, 78 pixels wide and 400 pixels high. As the form loads, how do I centre the nested panel?
x = Panel1.Width / 2 - Panel5.Width / 2
y = Panel1.Height / 2 - Panel5.Height / 2
If Panel5.Height < Panel1.Height Then

At the moment when i run my form1.vb program it runs in the top left of my screen, when i save it as an application and then open it from a shortcut will it still do this or will it open in the centre of the screen? In the designer it is in the top left of the screen, is there a way to move it here? as my assumption (which is probably wrong) is that the position it is in the designer is the position it is as an application? Is that right? and if it is how to i change the position in the designer?
View 4 RepliesBasically I currently have the following code which enables me to print the form perfectly.

However, with the coding above on the print preview the form screen shoot/dump isn't centred. So I was wondering what would be the way to go about doing it? This is using the printform in the power packs available btw.
Also I figured it might be using height/width/location/margins etc, but I'm not to sure how one goes about assingning values to them. Like the two above I commented don't work.
I have a single form windows application and here is my question; When I set the property of the form's start position manually to centre parent or centre screen it starts up in the centre of the screen. When I do the same thing in the form load event:

I am writing a Media Centre Addin in Vb.net and it was all going good until i got to the point where i want to find the "Currently Playing song FilePath or URl"I have spend a number of hours racking my brain to figure out a way of seeing what the "Currently Opened Files" are on a machine at any point of time.
My idea is to get all the currently opened files, and then filter the Extensions from these and find the media item that is currently playing, and get the filepath.Does anyone know how i can do this? and what methods or classes or Librarys i should be looking at or importing In..

I am calling the OTA API from HP Quality Centre and one of the calls requires sending a NULL. This is the actual line of code:

I have a tough situation that I don't really know how to code. I have one main list of point that contains all the points on a picture that are black.(1point=1pixel) I need to group all the black pixels that are less than 15(more or less) pixels away from each other into one Separate list. In the end I want about 5 lists.
What I said above is what I think is best to detect the centre of a shooting target. This information is just for those who think they know a better way. Each card has 5 targets on it and I need to detect the centre of each target. Ignore the sticker on the top target, in all cases the top one will look like the rest.
How do you get the current wallpaper? do you use SystemParametersInfo? what about the picture position setting?
View 1 RepliesI've made a program to change a computers wallpaper through VB which works perfectly UNLESS as your browsing for the picture you press the cancel button. The code on the browse button:
Dim dlg As OpenFileDialog = New OpenFileDialog
dlg.Filter = "Image Files (*.bmp, *.gif, *.jpg)|*.bmp;*.gif;*.jpg"
dlg.Title = "Select the image to load."

Is there anything that can be added to the code so that the user is able to cancel looking for a picture without it crashing?
I am developing an application for an emergency services organisation using VB 2008 that will enable users to select a map zone of a city centre and plot icons onto it, then save/export the layered map with icons as an image.My problem at the moment is that I am struggling developing the point where the user imports in the icon (for example, a flame icon where a fire started) and drags it around the map within the picture box to the required area.I want them to be able to select their desired icon from a series of commandbuttons and for the icon to 'appear' on the picturebox and be enabled to be dragged around and dropped as required. The organisation already has such a thing working in Microsoft Word (!) and that uses the ActiveDocument.Shape.LoadImage function on a pushbutton to import the icon and then it is placed on the map as required, but this is really unreliable for them.I dont even know if you can layer images onto an existin picturebox within an application in this way and then export as a flat image.
