Amend A List Box At Runtime?

Feb 24, 2010

i have been trying to work out how to modify a list box at run time ( i.e add in the detail when some presses a button ).I found some code in a sample program, which I thought I understood, but when a cut and pasted this code into my program, it didn't work as expected.The code which I cut and pasted was

Me.resultsView.Columns.Add("Match", CType(Me.resultsView.Width / 2, Integer))
Me.resultsView.Columns.Add("Position", CType(Me.resultsView.Width / 4, Integer))
Me.resultsView.Columns.Add("Length", CType(Me.resultsView.Width / 4, Integer))

[code]....

Obviously the top few line are meant to be column headers. Seem simple enough but they don't work in my program, I get no column headers.
When I run the program and pressed the command button, the only thing that appeared in the listview box was the word "This". When i pressed the command button again there was another instance of the word "This" appearing next to the original. The same thing happened the next time I pressed the command button.

Automatically Amend File Name?

Apr 21, 2009

My.Computer.FileSystem.MoveFile to move logs of a command line application to the directory that I want.The problem I'm having is that, if the file already exists, the program errors out. Which makes since.I could just use conditional logic to replace or rename the file if it exists. The problem with the former is that I need to keep all of the logs and the problem with the latter is that, without knowing how many files could exist, I wouldn't know when to stop renaming files.If I knew that there were only going to be 5 files, then I could work with it. But since there probably won't be a finite amount of files, I need something automatically amend the new log to another name. For example, if I had "Test", then the log would amend the next file Test1 and so on.

Copy Selected Rows And Amend/update Database?

Aug 10, 2011

I am trying to create a sign in program for my members. They come to the computer, input their birthday (already in the database), and up pops a Form with DataGrid that shows all the members with that birthday. Here is where im getting stuck. I want the user to select their name (row) from the DataGrid, click the button Sign In, and have the database be updated in the "Attendances" column to previous+1.

I first approached using the DataGrid1.SelectedRows.CopyTo method but had no luck. If someone could please help me to read which row the user selected, and then search the database for that persons name (which the row contains), and add 1 to a column in the database.

'Begin Code
DataGrid1.DataSource = Nothing
DataGrid1.Columns.Add("first", "First Name")

Combo Box List Populated At Runtime?

May 10, 2010

I have a project that currently uses an XML config file to create some groups. Based on these groups, you can search a database for information. What I want to do is create a form for editing that file. I can get to the information via messagebox, but when putting it into a ComboBox, I can't get the list updated. I have tried the text property which only populates the initial selection, and the Items is a read-only property. Nothing else looks close to what I want to do.

My other thought is to populate a datatable with the information and then populate the combo box from the database. It seems like an extra step that I shouldn't need, but it may be the only option right now.

The reason it can't be hardcoded is that the XML config file is already being used by a program, and the file may be updated from two or three computers, meaning I need a central location for the file.

Creating/Populating List Boxes At Runtime?

Oct 8, 2009

I am building a form that will eventually list a group of functions on the left. If you drag a function onto the form, it will create a listbox and a label at the loction you dropped it to. If you drag a function into a listbox, it will add that function as a listbox item. I have this working kind of. The problem is that once I create a new listbox, I am no longer able to add items to the previous ones. Here is my code:

Public Class Form1
Private MouseIsDown As Boolean = False

VS 2008 Load The "runtime" And "genre" Into Label3 (runtime) And Label5 (genre)?

May 24, 2012

I'm creating an app to manage the movies I've watched and get some info about these movies and then display these info in labels.At moment I'm trying to load the "runtime" and "genre" into label3 (runtime) and label5 (genre). Once the movie name is clicked in the listbox control, these info are loaded from a website (webbrowser control) and then displayed in the labels. My question is: Is there any way to make the My.Settings save these info for EACH movie? Something like this:

Saving the info:

vb
If ListBox1.SelectedItem.ToString > 0 Then 'LOADING THE INFO CODE... 'SAVING... 'create: My.Settings.(ListBox1.SelectedItem.ToString & "1") = Label3.text 'create: My.Settings.(ListBox1.SelectedItem.ToString & "2") = Label5.textEnd If

Create A Toggle Button That Switches A List To A Range And Then Back To A List If Needed?

May 14, 2009

II am trying to create a toggle button that switches a list to a range and then back to a list if needed. I am able to get it to do both but when I add an item to the list, convert to a range and then convert back to a list it leaves off the last items I entered.I tried to work in a code to select all cells but I must not be putting it in the right place.This is what I have so far:

ActiveSheet.ListObjects.Add(xlSrcRange, Range("$A$3:$AE$7"), , xlYes).Name = _
"List1"

I realize the problem is the $AE$7 (the $A$3 is correct)

DB/Reporting :: ODBC To SQL Server 8 Shows List Of Procedures But Not List Of Tables Or Views?

Oct 27, 2009

In VS 2008, VB.Net, I am successful connecting to a local SQL Server (version 8) and seeing all tables/views/procedures in Server Explorer. The local OS is Win XP Pro SP3. I created an ODBC data source to a remote SQL server (also version 8) with a database of the same structure as the local one. The connection tests out ok. The remote computer runs Windows Server 2000 SP4. In the VS 2008 Server Explorer I add this ODBC source. When I click on the plus-signs to expand items, neither the tables nor the views show anything, whereas the full list of procedures appears. Is it the old SQL Server version? Is it the old Server OS version? Something else alltogether?

Determine If Property Is Generic List<of T> Via Reflection And Loop List Items

Oct 1, 2009

I'm looping all the properties in an object via reflection:

For Each p As PropertyInfo In values.[GetType]().GetProperties()
If p.CanRead Then
'Do stuff
End If
Next

how to determine whether the property in question is a generic List(Of T)? If it is I need to loop the list itself.

I've experimented with GetType and TypeOf but have not managed to get anything working.

To clarify, I want to keep this generic. I do not want to specify the type of T, I need to loop the list items and call the ToString method on each item. T could be one of a number of different types (application specific reference types). Is it possible to do this without specifying types?
