I'm relearning VB.net just for fun, so consider me new at this. I'm trying to write a program where the user can input a list of names or numbers, and the program will randomly pick one of those names or numbers. So far, I can get it to randomly generate numbers based on what I put in the code, but I don't know what I should use for the user to input the data, and how to code it so that the program will pick from that data.
View 3 RepliesI 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 am going to create a windows form and add a push button (pretty simple right?) I want the push button to randomly cycle through about 10 pictures and display the randomly selected picture.
A few problems I am facing, 1) I do not know how to do do "randomization" in VB.Net and 2) I do not know how VB.Net would handle displaying an image, would it display on the form i am building or would it display in the default photo viewer for Windows?

I am trying to change the background randomly from a selected list after a certain amount of time. I have the array set-up and I have it picking a random path (ex c:images est.jpg). I found in the registry the background image settings. I tried setting the registry key to the path but it seems like there is more to it than that because it doesn't change it. I also saw where it stored the file and tried changing it but again it doesn't change it. The funny thing is if I go to display properties afterwards it shows the correct image just doesnt set it. If I then click a different image and go back to it then it sets it. How can I make it update the background?

I have a multi-threaded client and server application written in VS 2005. The server application runs thousands of SQL Server 2005 stored procedures and a lot of file IO. The client application does a lot of file searching, file IO, and string comparisons.Right now everything targets the 2.0 framework. Would it be advantageous to upgrade one or all 3 of them to the 2010 versions? I'm mostly interested in seeing speed enhancements. I haven't been able to find much saying 2010 is better than 2005.

View 7 RepliesI have an application that, when I finish it, will generate a graph of data drawn from a My SQL Database. It's going to be a simple time graph, with time on the bottom and a few stuff on the y axis.What I want is for the user to be able to enter the date. I would like it to be like a numeric stepper. Before I had two numeric steppers in the form but I decided one would be best.The idea was it would be like this: mm:hh [UP/DOWN ARROWS HERE]I saw one that was in use in an actual program. It had it so when you clicked the minutes, it selected the minutes and you could change them. The you could select the hours and change them. How would I do this?
View 2 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...

I need my code to be able to choose 5 random files from a folder. I was hoping I could instantiate the Scripting.FileSystemObject then grab the target folder as an object and do something like FolderObject.Files(12).Name but apparently that's not doable. What I did works, but is sloooow:

Folder = FS.GetFolder("c: emp")
