View 4 RepliesI am writing a Windows Forms Application using Visual Studio 2008 Pro .NET version 3.5 with STRICT and EXPLICIT options both ON.
I am having trouble using ".Start()" and ".Stop()" for my stopwatch method from other methods. I have tried several different methods of writing the line that calls the start and stop, but none work, and VS keeps sending me in circles with its correction suggestions.
Form Level
vb
Imports System.Diagnostics
Class Level
[Code]....
and promptly gives me the same error with no options for correcting it. The same thing happens for the stop command.
Is it possible to pause and start the timer (so the current time doesn't get reset when the user clicks the button the second time)?

I'm searching a stopwatch like: HH:MM:SS. I need start and pause buttons. How i do this?
View 16 RepliesI am a total newbie when it comes to VB but I'm starting off with a few simple projects I've completed already! Basically Ive seen MANY stopwatch tutorials but none so far have been able to do a simple format of Second and Milliseconds 00:00 and NONE have been accurate in the slightest and have been totally off! create a simple stop / start stopwatch that is actually accurate that would be great as Im going around in circles trying to find a tutorial on this!

View 2 RepliesSo a timer's maximum interval is 1 which is a thousand ticks a second. A Stopwatch's frequency is 2238906 ticks a second on my pc...
I am wondering if there is a reliable way to trigger an event for each tick of the stopwatch without missing any ticks...
If I can somehow get a Tick event for the stopwatch, I believe I can increase the resolution of my input recorder....

Is there relialbe alternative to Timer class in .Net?We are having issues with System.Timers.Timer and System.Threading.Timer, e.g., they start immidietly, or sometimes fire out after long period of inactivity (after 49 days).I've seen that there seems to be a lot of issues with them like here: url...We can not use Forms timer.We are thinking to pause the thread for certain period of time instead of the timer...
View 4 RepliesI am reading a file and loading the records read to a database. At the end of this process there needs to be a check that the counts match. This code was already written and the comment doesn't give me great confidence in it: ' Description: Get the number of lines in the record file. Thisshould give a good indicator of the number of recordsIt should or it will, using this code?:
Dim i As Integer = -1
Dim line As String = ""
Dim sr1 As StreamReader

Then i is returned as the count of records in the file. Is this the best way and is it reliable? Records in the file are delimited with a newline
What is the most reliable path to export data? I have a Access db used by many. I have a button that export the data to the desktop.

View 7 RepliesI see so many programs take command-line arguments with flags, for example gcc hello.c -o hello. Of course, I can implement that in my application:
Dim args() As String = Environment.GetCommandLineArgs()
Dim oi As Integer = Array.IndexOf("-o", args)
If oi > -1 AndAlso oi < args.Length Then
CompileTo(args(oi + 1)) 'Or whatever
Else
CompileTo("out.exe") 'Or whatever
End If
But it's ugly and annoying to use, prone to errors, and inefficient. What's the better way that I keep overlooking?
Does anyone know of a reliable way to cancel the ItemCheck event on a CheckedListBox? I am in a situation where the ItemCheck event should basically discard changes on a form, however, if the person decides to cancel the discard I would like the ItemCheck event not to fire so as not to change anything.
View 2 RepliesI eyed VB.NET 2010 Express and created the damn app. It's up and running and it does what it's supposed to do (in v1). Now I'd like to distribute it for free while:
(1). Have a reliable way of knowing (and everybody can check this out) the number of downloads.
(2). The app cannot be passed from one user to another, but has to be downloaded from the reputable biz (there can be more than one biz) that accurately provides the number of downloads.
(3). I can have total control over the app (once it's downloaded by the users), that is if I want to inform the users of updates or whatever, or if I want to add some ad windows to the form I can do it whenever I want and how I please.
How do I do (1) to (3)? What am I supposed to read to do (3)? ADO.NET and ASP.NET? Any shortcut? What's the easiest way of doing it? I'm not sure I'm looking for a career in programming, for now I just want to take this app off my shoulders and go back to daydreaming.

View 7 RepliesWe have a VB.NET program that needs to periodically call a function in an external, unmanaged DLL to communicate with our legacy application. We are having a problem with the application (seemingly) randomly not being able to find the DLL with the unmanaged code. Currently we use DECLARE FUNCTION blah LIB for the unmanaged code. Would it be better/more reliable to use DllImportAttribute instead? Or am I missing something else?
View 1 RepliesI have made my application to start automaticly when windows start (registry ../currentversion/run/appname + path). In this mode the application start minimized and an little icon appear in the notification icon area. With this icon you can maximize the app or exit it.If you exit the app and start it again using the Menu (Start/programs etc) than the application start in minimized mode (and in this case I would like to have it in normal mode) because the setting autostart is still true.Is there a way you can detect when the application start when windows startup using the above registry or when people click on an icon in the programs menu (or desktop)?
View 2 RepliesI'm using Process.Start method to launch another application from my application. Until today, there was no problem. But I have tested my application in a different OS, Windows XP (SP3), and my application didn't work right on that. I'm also using arguments to run that application. I guess for some reason my application couldn't send arguments to other application correctly under Windows XP. Maybe it is related to my code. But you should know, it works great on Windows 7.

I have a Listview on my form with different files. I can selet a file en open it with the proces start method. To open the file i use the OpenFileDialog method and select the filename. This work very good. With the code below.
My question is if there is a method to get the selected file without using the OpenFileDialog Box. So when i dubbelclick the selected file the proces will start with open the selected file. Something like:
proc.StartInfo.FileName = Me.SelectedCell.FileName
instead of proc.StartInfo.FileName = Me.OpenFileDialog1.FileName
PS) May be i can preduce the Filename using the OpenFileDialog method on the background.
Private Sub ListView1_MouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListView1.MouseDoubleClick
If Me.OpenFileDialog1.ShowDialog() = Windows.Forms.DialogResult.OK Then
