VS 2010 Detect When The User Stops Typing?
Apr 13, 2012
I'd like you filter some results in a grid, and i want the user to be able to type a value into a textbox, and then the grid will be filtered by that value. I don't need help with the grid or how to populate it. My question is in regards to the textbox; How can i tell when the user has stopped typing so i can automatically load the grid? I thought about doing a refresh automatically in the TextChanged event, but that seems silly since the user could still be typing more characters.

I'm using a custom webbrowser to display a special intranet for my company.I need to be able to display a custom keyboard whenever the user can type in the webbrowser. So if they click on a textbox within the page to type, this custom keyboard appears.when the user is in 'typing mode'. I thought maybe checking when the cursor changes to 'ibeam' which is the typing cursor? How might I do that, or is there an easier way?

I've searched around but can't find a clear answer for this. From my winforms VB2010 app, I'd like to be able to detect the country of the user's PC at runtime. Specifically, all I really need to detect is whether the user is in Australia or Canada.Most things I've seen will say "have a look at System.Globalization.CultureInfo", but with no clear example. I also know that the old-school "GetLocaleInfo" API can be used for this as well. I do have some code using the latter, which detects Australia when LOCALE_ICOUNTRY returns a value of 61. However, that won't work for Canada, as it returns 1, which is the same as USA (I know that these are based on telephone country codes).

For stopping by, is there a way to detect when a sound file (WAV) stops playing?
e.g.> There is a FORM with a PLAY button on which is coded to play a WAV file. But how does VB detect when the WAV file has finished playing?
Here is the code I have on the PLAY button
My.Computer.Audio.Play("test.wav", AudioPlayMode.BackgroundLoop)

Is there a built in way to know when a user is done typing into a textbox? (Before hitting tab, Or moving the mouse) I have a database query that occurs on the textchanged event and everything works perfectly. However, I noticed that there is a bit of lag of course because if a user is quickly typing into the textbox the program is busy doing a query for each character. So what I was hoping for was a way to see if the user has finished typing. So if they type "a" and stop then an event fires. However, if they type "all the way" the event fires after the y keyup. Like measuring the time since the last textchange event and if it was > than a certain value then it would proceed to run the rest of my procedures.

Is there a way to make the textbox stop typing when a user types numbers? I don't want an error message, I'd just like the user to be able to insert 10 numbers and then it shouldn't add any newly typed numbers.[code]....

In an application I have, when a user types in a textbox, the data in a listview is refreshed to reflect what the user is typing.As it stands, it does a refresh after each key is entered.Is there any way to smartly wait until the user has finished typing before initiating a data refresh?

This is in a RichTextBox. I'm making a string of sports stats and I need to have them aligned neatly in the RichTextBox. Here is an example: str = "12/24 (tab) 225 yards (tab) 2 TDs (tab) 2 INTs" When I use the vbTab constant in place of (tab) I run into problems as the size of the text in each column can be different which makes the tab not balance out correctly.

Been trying to figure out why my progress bars (one in the status bar when the main window is open and the other in a window by itself before the main window is shown) go up most of the way, then stop till the processing is done.I have refresh in there where the action takes place, and that made it work mostely.Basically I'm loading a file into a string, then while in a loop, I'm processing the file by lines. I have a function that retrieves a line, then it does a:
pbProgress.Value = pbProgress.Maximum - sWork.length
pbProgress.ProgressBar.Refresh()
StatusBar1.Refresh()

In my application I read data (using data binding) from an Excel spreadsheet into a DataGridView. This works, but the data columns contain text fields (strings). I would like to set the data type for some columns to "Date" and Decimal. I cant do this on the DataGridView (error: cant change properties for data-bound stuff) and I cant figure out how to do it on the dataset or data-table that I bind to the DataGridView.The following is the code I use to read and bind the data:
Using con As OleDbConnection = New OleDbConnection(cs)
'
'open the OleDbConnection
[code]....
The commented out code (below the 'Todo: comment) causes a additional table, but I want to change the table with the data.

Is there a way to find out if the "TextChanged" event is fired because the user is typing into a textbox or the programmer called myTextBox.Text = "something"? I don't want to react when the user is typing each letter into the textbox so I am using the "Validated" event to catch when the user is done so I can react. The problem is I don't have a way to catch when the programmer does "myTextbox.Text = "something". The only way I know to catch changes there is to use TextChanged but then I don't want to be reacting when the user is typing each letter into the textbox.

Once again I'm migrating to vb.net finally from vb6 and trying to get some of my old code to work. I was using the following code to let something finish running and then after the time set go to the next.
[code]...
Sleep just stops the code period but this actually runs the piece before it and then continues. I put it all into vb.net and it threw out an error with DoEvents.

I am using VB .Net 2.0. I know I can detect the OS using
System.Environment.OSVersion
Can anyone tell me if there's a list somewhere where I can find what that generates for different OS versions.
Specifically I am trying to detect if a user is running Windows 7 64-bit.

I have an application that when it starts, it checks the internet to see if a new version is available. My problem is this: If there is no net connection, the program 'pauses' as it tries to check for the new version.
Is there a function that I can use to detect if the user is currently online, with a working connection?

I'm trying to work out how to detect if the user has pressed an f key I have this so far:
Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Me.KeyPress
Label1.Text = e.KeyChar
End Sub
This detects when the user presses a character key and outputs it via Label1.text, but it doesnt work on all keys?

Dim hostname As IPHostEntry = Dns.GetHostEntry(TextBoxIP.Text)
Dim ip As IPAddress() = hostname.AddressList
TextBoxIP.Text = ip(0).ToString()
I have a windows form with the code above to get the ip address of the user. what would be the easiest way to get the country location of the user? based on the IP in the textbox. The solution doesnt need to be 100% accurate but good enough to work most of the time. the simpler the better.is there are any work arounds or built in fuctions for pulling a users country or language, this would be better than creating or managing a giant database.

I have a form where the user chooses a facility and then the list of patients for that facility are displayed in a data grid view. When I click to add a resident, the last name field on the data grid view is highlighted in blue below the last record that already exists.If I try to start typing without clicking in that cell, the facility changes - it looks like the control is still in the facility drop down box. How can I code it so that the user can just start typing in the data without having to physically click in the cell to start entering data?

No doubt a simple question, but I'm a beginner (I learnt GW BritingASIC in 3 months long ago - but after 6 months grappling with vb 2008 I am still bewidered).
I have written a program that asks the user at run time to choose 1 of 40 buttons. These are themselves defined at run time. Whichever button is chosen the same algoritm will run (using different data). Question: To save writing the same Button_Click routine 40 times, what code should I write - and where in the program - to detect which of the 40 the user has chosen?
