So here it is : how can iI get info about the file that user selected in windows ? For example: the user browse to C:windows (it isn't important where maybe desktop) through explorer and select a file ( he/she just select it, not open ). the moment that the file is being selected, how can I get info about that file? I think the file path is enough. I can get the rest detail with path.

View 6 RepliesI am using the OpenFileDialog component with a Button Sub to use the text file that the user selects (it can change everyday) in the next part of my program that will read that file and then covert it into an xml format. How do I get the second part of my program to use the file selected?
Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button1.Click
If OpenFileDialog1.ShowDialog() = DialogResult.OK Then
Dim sr As New System.IO.StreamReader(OpenFileDialog1.FileName)
MessageBox.Show(sr.ReadToEnd)
sr.Close()
End If

When .Clear() is invoked, is the memory freed up that was allocated when all of the items were added? I need to load several lists of codes from a database depending on the import selected by the user. Each list of codes will be a List(Of String). My idea is that I will load only small strings into a List(Of String) along with a List(Of <class>) for the data I will be validating and manipulating. When I am done, I want all of the data from the Lists to be purged from memory. Will .Clear() take care of that or does the memory still remain allocated and have to be dumped by the OS once memory gets full? (And, incidentally, what causes the OS to decide which memory blocks to dump? FIFO concept?)
There are so many lists, I'm not sure if I just want them sitting in memory or not. Granted, the lists will just consist of a single string value for each code pulled from the database. So there won't be a ton of data, so maybe I could just load all the validation lists at the beginning of runtime and only worry about purging the data List since it will contain between 35-50 "fields" per record and there will be a couple thousand records each import that is run. I don't want my program to actually cause a hit in performance in the long run. I ultimately don't see a problem because I won't be running millions or even hundreds of thousands of records at once, but I just want to be sure.
I need some help with the input validation of my application. Attached is the code that I have written as well as a screenshot of the front end.

Please feel free to critique my attached code. [Code]

After reading through a bunch of stuff, I was curious what production developers use for config files. I know that there is an app.config file that can be modified by the user of the program w/ settings. I also know I can create my own .xml file or .ini file to store settings as well. I wanted to know from the production side, what do you use and why?
View 1 RepliesI've mainly been doing ASP programming up 'til now, and I have a pretty simple question.
I'm creating a program that will copy a selected file to a selected directory, and I want to store recent files/dirs so that they can be selected from a combo box. I was planning to just create a settings with "files" and "dirs", and just store the strings as | separated values (since that's an illegal file character).

All things point to a database but for several reasons I can't use a database.
I have my desktop app, bound to an access database. I want now to improve a button so the user can make a backup of the *.mdb file.So i used this
If FolderBrowserDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then
If FolderBrowserDialog1.SelectedPath <> "" Then
FileCopy("BDGRACIA.mdb", FolderBrowserDialog1.SelectedPath & "/BDgracia.mdb")
End If
End If
It works fine when i try the app from within Visual Studio. But when i install it it won�t find the database because it was installed elsewhere.Is there a way to control where the DB is installed and follow that route? Does this depend on the OS the app is installed? Or did I face the problem wrong and i should do something completely different with my button?
I am developing an application that will call to the current user path so that a text file can be saved. I have seen a few forum threads that call to the current user path but I have been unsuccessful in making it work. Id like to try and save a text file, lets say 'test.txt' to 'C:Users(current user)My Documents' [URL] The above link has a way of calling the current user name, but when I publish the application, all it does is call to 'C:UsersMy Documents' and ultimately does not work. I have searched multiple terms and about 20 pages deep into google each time.

I'm building an online shop, but have run into a problem.When the user click that they want to add a product to their basket, i add the product ID to an array that is held on the session.This all works great and i display how many items they have selected etc..The problem comes when i get to the checkout page.Whats the best way of displaying the items that the user has selected?
should i use a datagridview? if so, how do i pass the array into the SQL in order to get all the data rows that i need?
should i use a repeater? this gives me the same problem as above though.I just cant seem to work out how to get the values fro the array and then run the sql for each ID to get the information to show on the screen.I could loop through the array using each ID as a parameter in the SQL but then where do i put the data? in a dataset? a datatable?
