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'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.

I'm using the code below to take a string and split it up into an array. It will take: Disney Land and make it two separate elements. If the string contains "Disney Land" then it is one element in the array. Works great, however it adds some empty elements to the array each time. So I just iterate over the elements and remove them if they are empty. Is there a tweak to the code below that will prevent those empty elements from occurring?

I am wanting to take a string of say the following:

So that in C# or VB get a match set of:

Essentially it splits on the spaces unless there are quotes around the spaces, then those words between quotes are considered a single phrase.
i wanted to link options selected from Comb box A (general) to specific options in combo box B (specific). I want to pick a word in Combo box A that has specific words/phrases in Combo Box B show. But not all the words to show in the combo box B if they aren't associated with the Word picked in Combo Box A. Ex.When "Soda" is picked in A, only "Coke, Sprite, Fanta" should be visible in combo box b, not everything else.This is the code i used to make the boxes, but i don't know how to link them.

how to get different backcolors and how to change them using ListView.ItemCheck.
I am using ListView in a self written control (basically to improve padding). In some deployments, CheckBoxes is set to true and I use a RaiseEvent to return the Index of the row selected using an ListView_SelectedIndexChanged event.
In other deployments, I am using the control with the CheckBoxes set to false. But clicking on a row does not fire the ListView_SelectedIndexChanged event to be able to use RaiseEvent to return the Index of the row chosen. I have tried using a MouseUp event to capture the mouse Y coordinate. But conversion of that coordinate to an Index position is both inconsistent and inaccurate with my primative code of
return = (point.Y - me.top) / some constant
I have used ItemHeight on a ListBox in a similar situation but ListView does not have an ItemHeight property.
how I can capture the Index of a row clicked in a ListView without checkboxes?
I would like to know if there is a command to make a program choose between certain integers. For example, I would like my program to make a random choice between the numbers 12, 118,224 and 300.

View 6 RepliesI have a VB.NET application with a connection to an SQL Server 2003. On the server there are two databases, MyDatabase and MyDatabase_Test. What I would like to do is to show a dialog when the program starts that let's the user choose which database to use. My idea is to create a new form as the starup form that sets this property and then launches the main form.Currently the connectionstring is specified in the application config file. Best would be if I can specify two different connection strings in that file to choose from, but for now it is also acceptable with other solutions like hardcoding the two connectionstrings into the startup form.EDIT: In the dataset.xsd file there seems to be the relevant part
<Connections>
<Connection AppSettingsObjectName="MySettings" AppSettingsPropertyName="MyDatabase_ConnectionString" ConnectionStringObject="" I

I have multiple comboboxes(12 total) on a form.I am attempting to update some settings from what ever the user selects from the combo boxes. I am trying to keep the code as small as possible, so I thought about having all the comboboxes have similar names only different by a number being changed at the end. (ex: cbo_1, cbo_2, cbo_3, etc...)And using a For next loop to advance through each combobox and update the settings as the for next loop advances.(This might be a stupid way of doing it, but its the first idea that came to mind.)

I'm trying to design a windows form application. By default, .NET had put Tahome 8,25 on toolbar and Microsoft SansSerif 8,25 on everything else. To improve general look and feel of the forms I'd like to change them.
Which font family should I use as a default? And what size should they be?
For:
Classic data input form (label + textbox, label + combobox...)
Data grid
Is there any recommended way?
