I'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."
[code]....
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 just want to write a function which will set the Vista's wallpaper using the file name supplied.

View 2 Repliesi got this code to change the desktop background from a forum.[code]the SetWallpaper function was written by me as the ChangeWallpaper only works on .bmp files.all these code works but my problem is that i need this wallpaper to be stretched because some of my pictures are smaller or larger than 1280 by 800 pixel which is my pc monitor dimensions. i've tried to tweak the ConvertBitmap function (as you can see in the comments) to produce bmp's to my screen size but it doesn't work.i need to set the pictures (.bmp or not) to be stretched and i don't know about dlls and stuff

Short I want to write an application that loads a swf file (or html file containing the swf), and uses it as desktop wallpaper.
First off, is this even possible? Second, how can I do something like this (If its possible)?
change user agent permenantly in my app? i currently use webbrowser control only to browse 1 site which needs to be on mobile skin to look decent in my app.the only way i can do this, is if i change user agent to mobile device like apple iphone (example)so i tried this:
vb
WebBrowser.Navigate("http://se-board.com/index/index.php", "_self", Nothing, "User-Agent: Mozilla/5.0 (iPhone; U; CPU like Mac OS X; en) AppleWebKit/420+ (KHTML, like Gecko)

What I want to do is to make my application to SendMessage to another application. I can send message perfectly when i set keys.F1 or F2 etc in code but, I wonder, is it possible that user change this key in runtime? I was thinking about doing something like:
If combobox1.text = "F1" then
SendMessage(pHwid,WM_KEYDOWN, Keys.F1,0)
elseif combobox1.text = "F2" then
SendMessage(pHwid,WM_KEYDOWN, Keys.F2,0)
etc...
But I have 19 usable keys and alot of events with SendMessage function so code will be so big and there's possibility for slowing application. Is there anything that I can do, like...
Dim hKey as STRING? INTEGER? WHATEVER...
SendMessage(pHwid,WM_KEYDOWN, Keys.hKey,0)
?
How can I change the headers (User-Agent, etc) for my webbrowser control, not just for the first page that I browse too, but for all pages.
View 1 RepliesI have a project where I added visually and successfully a datasource of MySql. I binded a datagridview with a table.
But, how do I change programatically the password, ip or user to connect with the MySql server? Because it can change at any time, so I can let the user change these values.
How do you get the current wallpaper? do you use SystemParametersInfo? what about the picture position setting?
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...

How can i get the current desktop wallpaper?I just want to save it somewhere thats all nothing complicated.
View 10 RepliesI'm trying to update my wallpaper with VB.NET and it's not working. Weird thing is, this same code works fine on my other machines (same OSes, Win XP Pro SP3). My code grabs a random picture then passes it to the SetWallpaper function:
<System.Runtime.InteropServices.DllImportAttribute("user32.dll", EntryPoint:="SystemParametersInfoW")> _
Public Shared Function SystemParametersInfo(ByVal uiAction As UInteger, ByVal uiParam As UInteger, ByVal pvParam As System.IntPtr, ByVal fWinIni As UInteger) As <System.Runtime.InteropServices.MarshalAsAttribute(System.Runtime.InteropServices.UnmanagedType.Bool)> Boolean

I have a logon script which changes the desktop brackground picture in the registry. The only problem is this change isn't applied until the user logs off and on again. I currently use a small program which uses SHChangeNotify(&H8000000, &H1000, 0, 0) but this will not refresh the wallpaper. I was also hoping this would refresh the Taskbar because I change a registry setting which removes a toolbar.

View 1 Repliesim making a Desktop Wallpaper Changer, using a timer to change the wallpaper after a select interval. I have 13 images in my directory numbered 1-13.
But im getting an error when it reaches 13 , is there any way i can maybe loop it ? so that it select no.1 again and repeats the process?
I am currently creating a tool that can manage local user accounts on Windows-PCs. I am using the functions described on
this MSDN page ; and after some struggling, I got most of them to work.
Unluckily, I haven't found a way to set the option "User must change password at next logon" while creating a new user account. I use the
NetUserAdd -Function to create the new user. I set the level to 1 and supply a
USER_INFO_1 -Structure . This structure accepts flags, and the flag UF_PASSWORD_EXPIRED seems to be exactly what I want - but when I set it, the user can log on without changing the password first...
I'm developing on Windows 7 Ultimate 64-Bit using Visual Studio 2010 Express.
Here's my code:
#Region "Constants"
Public Const UF_PASSWORD_EXPIRED As Integer = &H800000
Public Const USER_PRIV_USER As Integer = 1

View 1 RepliesI'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've created a desktop wallpaper changer and added some animation part to it.
View 2 RepliesI wish to make a wallpaper changer that can select a random wallpaper from a given directory and sub directories. I'm not asking for code at this point, I'd like a reality check to see how hard this could be. I'm still quite a newbie at VB so I just wanna check if what I'm thinking process wise would work.The basic thing I'd like to do is have it pick one picture out of a given dir and sub dirs. Then set it as the wallpaper. I'd like it to be resized if larger than the desktops resolution to fit inside it, no stretching cropping or stuff.
That's the simple things I'd like it to do. Unfortunately I have dual monitors so it'd have to pick two wallpapers, resize each one independently, stick them together, and then set the wallpaper. I'd also like to make a kind of simple database which would have the name of each pic and two values with it. I'd like a value to mark if it's been used already which would be reset when all pictures have been used. The second would be a simple tag. This way i could have all car wallpapers listed as tag 1 and all non-car wallpapers listed as tag 2. Then I could chose whether to use all or only tagged wallpapers.
iv been making a automatic wallpaper changer useing the timer, listbox, and picturebox , it works, untill i minimize it then it stops changeing the background, but when i maximize it it has actually moved down the listbox of pictures each time so the timer must be working when minimized, just it doesnt change the wallpaper when its maximized it always works,
