It's usually happend that I have some arrays with same length. For example name(), surname(), age() Is it the best way to leave all info in 3 arrays or it possible ( better ) to concatenate somehow?
View 5 RepliesI am working on a media player, and I would like to setup a local playlist feature. I am using a single ListBox and its "Display-" and "Value-Member" properties. 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 18 RepliesIn VB6 I load a recordset containg all of the records (6 fields per record)in a table into an XArray and then manipulate the records in the array and then write them back to the original table. The array issorted by the first field (1 to maybe 8000 or more) I need to find records in the array by an ID field and then move them (because of some external criteria that happens many times) from say number 400 to number 375. Then all of the other records between 375 and 399 were renumbered up 1 to fill the gaps left by the move.
The XArray worked well as it could find and also move to a next record easily to facilitate the revisions to each record quickly. Everything is done in VB6 in code and nothing visual needs to be shown to the user until say 2000 of these external changes are complete. What is the best, most efficient way to do this in the .Net framework in VB2010. Datasets, Dataviews. tableadapters, arrays. enums ?
My assignment is to have a user enter in big integers using what i think is two parallel arrays. I got this far but now im stuck. I think i need to actually convert the text box input into an array but i do not know how to do that. I am all over the place in this project.

I have a VB.net console app and I am opening a function in a dll written in fortran. I am passing 3 arrays through the function by reference. When they come back out the otherside they ahve all tunred to arrays of only one element And that element is 0.I read on the internet somewhere that when doing this kind of thing it is a good idea to only pass the first element of the array into the function.I tried changing my function declaration to accepting single elements rather than single dimensional arrays, and now the arrays are the same length before and after the function call, but they don't seem to be changing at all, so i'm not sure that this is working

way to "reset" a tooltip, so you don't have to leave and re-enter a control to make it pop? I have a form that is pretty much entirely taken up by one control. I want to have its ToolTip text change based on which region of the control is being hovered over (which I can do now). I just have to leave the control and re-enter it to make it pop. I'd like to have the Tooltip pop, then if I move the mouse to a different location (still inside the control's bounds) have it pop-able again in the new spot.
View 5 RepliesI am working on a new assignment. Our instructor wants us to code a shared leave event for three textboxes (txtBox1, txtBox2, txtBox3).I understand how to code the shared event and how to make a generic tbox for it:
Private Sub txtDescription_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtBox1.Leave, txtBox2.Leave, txtBox3.Leave
'generic textbox
Dim txtText As TextBox
txtText = CType(sender, TextBox)
We are told that if the generic textbox contains data and the data has been modified (against the database record), we need to : Determine the name (name property) of the textbox that casued the evend and Determine the value (text property) of that textbox.I know to check to see if anything is in the generic box by the length property, and if it is modified by the modified method, but how do you determine the name and value? Is it a case statement?
