I have an option for the user to choose their own background for the application. How do I then make the image save in the settings for the next time the user starts the application? (This is actual pictures not solid colors).
View 7 Repliesis it possible to choose different colors of different pixels on the background property of a form in vb.net?
i would like to clarify that i do not want to use an image to color the form.
i have a transparent form that will need to detect all the black colors behind it
How do I give the user a color chooser for the background of a form or anything else? I would like to be able to give him all colors in vb.net.

View 5 RepliesHere is a simplified hierarchy of a application I want to create:
1. Mainform - here should be a navigation pane, where a user can choose which modul he wants to use.
2. Childform Reports, Childform Maintenance, Childform To Do, Childform Management, ... - depending on which modul of the program the user wants to work with, a proper childform will appear as the main working part of the application
3. Childform CostReport, Childform TurnoverReport, Childform EmployeesReport, ... - if user wants to work with Childform Reports (chosen in 2. paragraph) he can work with one of these childforms.
I wanted to do this with MDI childforms, but visual basic keeps telling me that a form can be a MDI container only as a toplevel, which Childform Reports isn't. So i can make the program till 2nd paragraph but when i want to make the 3rd, its a problem.
I put the error here: "Top-level style of a parented control cannot be changed.
Parameter name: value"
Is there a workaround?
Maybe i could use TabControl for the 3rd paragraph, but its not that convient, since I want to use more "tabs" or forms...
This is my first web-based application using VB 2008. I had no idea where to start so I just chose the 'Wpf Browser Application' and started adding the controls on the form and naming them the same as I would do with a normal non-web-based vb app. I ran the XBAB file under bin/debug using IE and the form showed up but I couldn't enter text or anything even though the textbox was set to enabled?

Final step in my application. I finally got all the requirements working, but now I need to have the application run in the background.
The application was written in Visual Studio 2010 VB, Win form app.
The requirements are as follows:
1.) run the application at start up
2.) no icon
3.) always in focas
4.) always runs in the background.

I am currently working on a family project which is based on "Who Wants To Be A Millionaire?" show. There is a huge diffrence between the show and my project. My project is a christmas edition and the goal is not to get money or something, since I will not add it... Erhmm... Let me get to the point. I have already designed a layout and scripted some things. I have about thirty questions but I do not want them to always spawn in the same array, if you know what I mean. I want the program to randomly choose one of those thirty questions and NEVER choose the same question in the same program run. By the way, there are four options on my project: A, B, C and D. I have got everything, I just need a code.

I have developed a very simple application that disables system keyboard commands (ctrl+alt+del, alt+tab, etc), hides the taskbar, hides the desktop, etc.Upon entering a password the user can 'unlock' these options.This is being used with a restaurant POS system so no accidents can happen. However there seems to be one minor issue:In a separate software package (the POS software), at specific times, any application that is running (my locking application) will get focus and end up on top of the POS software.I want my locking software to remain underneath all running applications. Anyway to keep my locking application from gaining focus? I was thinking of maybe adding some line of code to send my locking application into the background whenever it gets focus..

View 4 Replieshow to re-write my application (http:[url]....) to be multi-threaded using the background worker. The use case is something like:
1. User opens a binary file, it can be several Gbytes in size so reading it into memory isn't practical.
2. User can then navigate through the file in 188byte chunks, data is read from disk, decoded, and displayed for each chunk in turn.
3. User may want to search for some data or build a report. This will involve repeating the read, decode, display, function multiple times. During this looping the GUI stops responding and there is no option to cancel so I want to make it multi-threaded. So, is it safe to open the file in the GUI thread and then read from the file in the background thread? I currently use something like this to open the file once:
Dim fi As New FileInfo(filepath)
fs = fi.OpenRead()
and then in a separate sub multiple calls to:[code]..........
I want to access a 3rd Party application in the background with the SendMessage method. It just needs to send a "space" to the software to trigger an action. It is important that this is done in the background because its a periodic event (ca. every 10 seconds), and it should be possible to simultaneously work on the same machine.
I tried to use the same approach which is shown in [URL]

View 2 RepliesI'm writing a command-line application in .Net. The app itself is fairly simple, but it has to connect synchronously to a web-service, which in turn has to connect to a Oracle database, and those pieces are fond of taking their time.
Is there a straightforward way (without dividing my app exe in two) to continue executing but nonetheless yield execution to the command prompt?
It's Windows, so no "&". Also, I cannot use cmd.exe's "start" cmdlet.
