Making The Program Response To The Enter/return Key Inside A Textbox?

Feb 14, 2009

I'm looking for a solution for making the program response to the enter/return key inside a textbox. After browsing the forum I end up with this

Private Sub TextBox1_KeyPress(ByVal Keyasii As Integer)
If Keyasii = 13 Then
Label1.Text = TextBox1.Text
End If
End Sub

As this seems to be the answer to the problem, I still can't make it work. I just get a 'beep' and nothing happens.

Return Inside Try/catch/Finally?

Sep 15, 2009

I have a (begginner) question on VB.NET. Is this good code (I mean, is it "bullet proof")?. It seems to work, but I understand the Return is executed AFTER the Finally. So how does it call a method on an allready disposed of object?

.net - What Character Value Does Control + Enter/Return Key Send

Feb 11, 2010

We have a multi-line control that we are attempting to prevent the Enter/Return key from being used to create a new line.Strangely enough, "AcceptsReturn" as False does not prevent this.So we added the following:

Private Sub txtAddr_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtAddr.KeyPress
If e.KeyChar = Microsoft.VisualBasic.ChrW(13) Then
e.Handled = True
End If
End Sub

This works fine, however one of the QA people discovered hitting Control + Enter still puts in a newline.How would we prevent this?And why does AcceptsReturn being False not work as it appears it should? What is the intended purpose of it?

Hit The Enter Button Which Is VBCrLf(carriage Return And Line Feed)?

Jun 3, 2012

I've seen this type of line in many post on here..I been rolling this over in my head and i think that this line or something close to it is a bad idea. For index As Integer = ListView1.Items.Count -1 the above line assumes that on the last line the person has hit the enter button which is VBCrLf(carriage return and Line Feed) in which case the above line would be ok..however if the last line does not contain a CrLf then you in effect are skipping the last line.

Error - Catch Cannot Catch Type 'Microsoft.Office.Interop.Outlook.Exception'

Mar 25, 2011

I have a program in VB.Net that receives mails from Outlook, extracts attachments and inserts the attachments into a table through a query. I would like to put the query/queries in a Try/Catch block, but cannot do so as Outlook exceptions cannot be caught, and it gives me an error, and unless I put a very specific exception, I cannot catch it. Is there a workaround?


Catch ex As Exception
End Try

Exception is underlined and when I hover on it, it says: "Catch cannot catch type 'Microsoft.Office.Interop.Outlook.Exception' because it is not in 'System.Exception' or a class that inherits from 'System.Exception'". This is affecting all my other code which I'd like to put into a Try/Catch block.

Catch Log4net Exceptions / Use Try / Catch Approach

Jan 23, 2012

I need to catch log4net exceptions (its own exceptions not app exceptions logged by it). I wish there's a way of doing it this way: [code] I have this code implemented and there's no errors in compilation but i force log4net to have an error (pointing to a non existing database in the config file) and nothing is threw.I've tried the listener aproach: [code] and it's writing the errors to log4net.txt, the forced ones i mean.This last aproach has a couple of drawbacks: it won't append every error to the file, if the error is the same it doesn't write it, i can't get the listener to write every error to that file, only one (I don't know how to fully configure the trace listener, it might be that). Thus it won't append the date and hour to every line wich is a necesity for me. Finally i can't give structure to it (xml). Even if the listener work i need to use the try/catch aproach, since i'm using ExceptionHandling from Enterprise library to log the errors in my app.

Textbox.Select() Also Add The Enter Key

Apr 22, 2012

I have a validation class that I use to validate data entered into textboxes on my form. If the data entered does not pass the validity test then the function does the following: [Code] All that works like a charm BUT What triggers the validation routine is when the user either presses the Enter Key OR the Tab Key. If the data is validated the next textbox, (textbox2) is populated with the same data as textbox1 and given the focus then waits for the user to enter new data or press enter which the goes through the validation routine for that textbox.

My problem is way back at the first textbox when the user enters invalid data. As I mentioned above the validation routine populates the textbox with valid default data BUT It also seems to somehow include the enter key because once the default data has been entered by the validation routine it then re-evaluates the data as though the user had pressed enter. Because the data is now valid it moves to the next textbox and never lets the user enter his/her own data.

Enter Information Into Textbox1 And Textbox 2?

Apr 8, 2012

So what i have is textbox1 textbox2 and richtextbox1 I want to enter information into textbox1 and textbox 2 and then hit submit so it records the data in the richtextbox as if it is a chart.

My current code for this is RichTextBox1.Text = TextBox1.Text & (" | ") + TextBox2.Text & (" | ") + "Pending"

But every time you hit submit it erases the current data and puts the new one. i want it to record it on 1 line, then when u hit submit again it will go to the next line in the richtextbox and record the textbox information on that line and so on.
