Oct 27, 2011I have a timer1 and it's interval is set to (1000). I know i can change the speed in a button or something like this:"Timer1.Interval = (2000)" but is it possible to make it so it RANDOMLY changes? Like when the timer1 is ticking, maybee it will change every time to somewhere between 200-1000 ? So its not EXACTLY a preset exact time interval.
View 2 RepliesFlicker Free Listview / Add A Row At Slow Speeds
Jun 1, 2005I'm using a listview control as a log window for a self-made FTP client application.Sometimes I need to add a row at slow speeds, but also sometimes a lot of information (50-100 rows, like dirlistings, login messages of FTP servers) has to be added to the listview within a For/Next loop.Now adding rows very quickly makes the listview flicker in an ennoying way. So much, the listview is hardly to read.For me, it is important I can see every row added (using different colors to know different meanings).Searching the internet, I find solutions using BeginUpdate & Endupdate of the listview control just outside the bounds of the For/Next loop. This makes that the new rows are displayed only when the For/Next loop is complete.Does anyone know a solution to significant reduce the flickering (maybe without using BeginUpdate & EndUpdate?), but where I still can see every single row added?

Feb 2, 2010it's capability to serialize objects. In a future project I will be creating dictionaries which have a Long as a key and a Collection as an item (itself containing two other long values). These dictionaries will be large, containing around 300,000 entries.
I've worked out how serialize and deserialize the dictionary using a binary formatter.
To serialize I use:
Dim myDictionary As Collections.Generic.Dictionary(Of Int64, Collection))
' I fill the dictionary with 300,000 entries here

VS 2010 Detecting Laptop Lid Close
Nov 16, 2011I've been searching this for quite a while now, but I've come up with very little so far. I need to figure out how to determine when a laptop lid has been closed so an execute an action when this occurs. But the power settings will be setup to where the laptop does not go into sleep or hibernate mode.
View 5 RepliesVS 2010 Detecting Lid Close Change
Dec 7, 2011I've been attempting to determine if a notebook's lid has been closed when the power setting is set to "Do Nothing."I was able to get this to work by trapping the WM_POWERBROADCAST message, but it would only work when the computer when to sleep. I've tested this on many different notebooks and the results vary. Even when changing the power settings correctly, the results were fairly inconsistent.So I posted this question in General Developer and penegate offered a possible solution.[code] I'm thinking that maybe the message I'm trapping isn't correct, but I'm not 100% sure. When I Google that message, nothing comes up. Two links appear. The one on VBF and some German site. Nothing's on MSDN.

View 6 RepliesVS 2010 - Detecting Mouse / Keypress Input
Dec 5, 2011I am creating an application that creates scripts to move a mouse and to click where a user wishes to via pre-programmed code and to also press keys where required. I have the code to move a mouse and to manually click anywhere. What I am after is to detect when a mouse button is pressed and dragged and when keys are pressed.
I see that there is the following
MouseButtons.ToString
To detect when a mouse button is pressed, and have it looping in a timer. Is there a better way to do this? I would rather not use a timer. And is there a similar routine to detect which keys are pressed?

View 4 RepliesReading EXCEL In 2010 Detecting Blank Cells
May 16, 2012My Visual Basic .Net 2010 application reads data from an EXCEL spreadsheet which will be generated by my "customers". The responses to Alkis last year (23 July 2011) has been a big help and got me over a hump in my application. Now I am down to the last issue - how do I detect a blank cell? Valid data is numeric, starts at a fixed cell (A5 to be specific), and will be continuous until it ends with blank cells. While blank cells appear to print a "zero", when I try to use zero as an end criteria I get a 'System.InvalidCastException'. When I put in a specific end value (-1) in the last cell all works fine but that, of course, is an invitation to a user error.What is the difference between "Value" and "Value2" and where might I find documentation that explains the difference?

View 1 RepliesVS 2010 Launching New Process & Detecting If That Process Has An Error Message
Nov 19, 2011I am working on a small VB application that listens for commands sent from an Android app.
One of the functions is to extract an archive. I am familiar with how to listen for the unrar process to finish, so I can display a progressdialog on the phone while the extraction is happening, and clear it as soon as it's done.
BUT ... if there is an error/alert from WinRAR, WaitForExit() never gets called because WinRAR is still sitting there open until I click "OK" on the MsgBox.
For Example ... if you try to extract a file that is not actually an archive... an alert will pop up saying "No Archives Found", and basically everything is halted on the VB app and the Android app, and the Android app just sits on a progressdialog saying "extracting..." until you manually hit "OK" on the computer.
As you can imagine, this is a problem if the whole point of your app is to NOT have to go over to the computer.
So... I am wondering if there is something similar to WaitForExit() that will wait for an error and allow me to close out the alert and let the process end.
Here's my Sub for the UnRar command:
Private Sub UnRar(ByVal WorkingDirectory As String, ByVal filepath As String)
Dim objRegKey As RegistryKey
objRegKey = Registry.ClassesRoot.OpenSubKey("WinRARShellOpenCommand")
