The display is the song's Artist and Name, and the value is the song's file path (i.e 'C:UsersUSERMusicetc.').To write the file path to the .txt file, I believe I can use the following code:[code]

View 2 RepliesI want to write a program to do Markov chain, but my states are quite large. First of all I calculate all the transition probabilities and revenues for all states(1381860 total states), and store in a multidimensional array. Public RevArr(0 To 9, 0 To 750, 0 To 282) As Long
After that the iteration of markov chain should use these as inputs to calculate the steady-state probabilities. But when I try to run the main code I got this error.Exception of type 'System.OutOfMemoryException' was thrown.
The following is the declaration of second array I add just another dimension for storing all the iterations, but I get this error. Dim stateprob(IT + 1, 0 To 9, 0 To 750, 0 To 282) As single

View 4 RepliesI am trying to do a form it has 2 comboboxes and I have the arrays set up one of the combboxes is for pizza size and it has 4 selections and the other combobox is for crust style it has 2 selections. The user has to pick on of each and it pills the price from the array and then displays the price in a text box.

View 1 RepliesI'm learning about the cultureinfo and doing ok but there is one thing I can't work out.I'd like to know how to find out the display settings of the date for the user pc.For example, I have an American bought laptop using the us culture so the date will be MM/dd/YY but I have changed the date setting to read dd/MM7YY. So that means I haven't actually changed the inbuilt cultureinfo, I've just "altered" a setting and it's that setting I want to access. When my project starts I have a label that I want to read as dd/MM/YY.With another pc it might be different - the culture might be uk but the date setting might be changed MM/dd/YY so I want the label to read MM/dd/YY etc etc etc.If the cultureinfo hasn't been changed then I want the label to read whatever the date is set to etc.

View 3 RepliesI am wriing a vb.net windows application to log and store information. then display it in a sortable multiple column listbox (I personally like FlexGrid by Component One). However... I am not sure how to go about storing the information. Should I go with a .sdf file database, registry, simply storing them in a file, or some other method?
What I need is to be able to:
read/write/delete from it
read possibly up to a 20mb file and sorting it without a lot of lag
be transported to multiple systems and maintain these writes (installed on many systems)
I know I could split up the reading/writing to anther thread. Even to other .DLL's and whatnot. But as for storing. Not sure what the best option is.

My question is, what is the best way to manage GUI locks/unlocks for the different states of the program. IE: If I'm in a "insert" mode, some GUI elements should be enabled, and some not. If I'm in the "read-only" mode, a bunch of them should be disabled... etc.

I have a bit strange problem in my application. I have more binding sources then one in my different forms. All of them work great when editing, deleting the data except one. But this one is a bit different from others. I'm using it only for updating and deleting. You can't add new records using it. And also its dataset doesn't contains any Insert commands in it. That's the difference.Now problem is:
After deleted the rows (using BindingSource.RemoveCurrent), it doesn't mark rows as deleted. I call BindingSource.Count method after deleted rows, it sill counts deleted rows. So it seems it doesn't update the dataset. But it is. Dataset.HasChanges returns true.
