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.

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.

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")

Is possible to add, a file to the solution explorer, and setup, at compilation time, the file to be automatically copied to the output directory. I wish to copy it to a subdirectory, but it looks like there is not an option other than the output directory. I cannot embed the files as a resource, because the user should be capable of modify or replace them. There are other options, as content files, but I cannot find how to manage them, or if they are useful for this purpose.

I'm trying to figure out how my program can automatically select a file to upload. I use the following to open the dialog box:
wbMain.Document.GetElementById("upload").InvokeMember("click")
and the focus is on the input, so i was thinking i could just directly send the string of the path of the file i want to upload. So I used SendKeys.Send(FilePath) But nothing happens. This is on a try/catch and I'm not getting any error either. How can I make this work?

I'm trying to make an HTML Editing software with vb.net and one of the features is debugging with a webbrowser. I want the webbrowser to open up the file that the user is currently working on.

I started making a program, and I wanted to insert music to play. i just added music to the resources and used the code my.computer.audio.play(my.resources.name_of_the_file and so on. this worked perfectly until I added the 5th song. the resource file became to large and vb said it was corrupt. so I thought of a new way: making a music file opener. I made a code so a window opens where you can select your .wav files. that all worked, but I couldn't get it so the music would start automaticly or that it would actually play. this is the code I have so far:
vb.net
Dim Open As New OpenFileDialog()
Open.Filter = "Wav [*.wav*]|*.wav"
Open.CheckFileExists = True
