I have got quite a messy text file and put it in a list box so I can extract certain information from it. I need to interrogate it a line at a time and ask things like, 'what number comes after this word' and 'ignore this line if it says this' . Is this possible using the list box loop method (which I have only heard of never used) and does anyone have any examples of code? I'm on the latest VB Express.
View 16 RepliesI want to remove items from a listbox 1 at a time. I have two timers set up to remove the two types of items that are put into the list box. When there is a "Player 1 killed Button 1" following a "Player 1 killed Button 2" or vise-versa they get removed at the same time. Is there any way to prevent this?

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?
