how to capture the text that a user enters in a textbox when they press the enter key? I thought there was an event that handles this but I can't quite seem to get anything to work.
View 3 RepliesI am using VB.NET for Windows applications. What is the difference between Load event,Activate event and Enter event in the Form and in which order the above event is executed.
View 2 Repliesthe scenario is the following: I have a textbox ,next to it a button. The user types a value in the textbox, he presses tab, I search this value in the database in the LostFocus event, if there is no match, a browse form shows and the user can select the desired value. After closing the browse form, the focus goes to the next textbox control (and exactly this I want to prevent). The user can click the button next to textbox to choose a value (the browser form appears), but in this case, after closing the form, the focus remains on the textbox control, because before clicking the button, the focus was on it.
So, my question: how can I disable the LostFocus event? Ok, I figured it out: I must use the validating event. It works. But in this case, if I close the form, the event fires up. How can I disable this?
I am finding it strange that the lostfocus event is always executed once when I launched my application. in my lostfocus event, I have some code that queries the db based on the textbox value. It is supposed to be 13 characters. So when i launched my app and presses the first character in the textbox, it is givin an error. When i debug the application, I found out that the lostfocus event is getting called once when i start the application.

View 3 RepliesWhat did I do wrong below? When I pass the enter key but for somehow the enter key event doesn't get triggered.
CODE:
I have a method in place to capture the "Enter" button when pressed and then move to the next control in the tab order. I do this to mimic Access (my users are spoiled).The problem arises when the current control is TextBox. I changed all my TextBoxes to multi-line and it got rid of the beep. However, it also added a "carriage return" and entered it as such in the DataBase.

View 6 RepliesWith a listbox visible, I have clicked on the windows form hoping to use the listbox.lostfocus event to let me hide the listbox - but the event does not occur. I suppose I can use the form.click event to hide the listbox, but how would I get the form to accept focus?
View 2 RepliesI have a TextBox in a Windows Forms application in VB 2008 (.NET 3.5) where a user can key an estimate amount. I am allowing them to key dollars and cents, and I want to round to the nearest dollar. The original code had the rounding down when the data was written back to a table, and that worked fine - I have this code in a "Save" routine that fires when the user moves to a different screen or record:
Dim est As Decimal : Decimal.TryParse(txtEstimateAmount.Text.Trim, est)
Dim estimatedAmount As Integer = Math.Round(est)
I decided that it might be nice to actually do the rounding as soon as they leave the field instead, so they're not surprised when they reload the screen and find that 1822.60 is now 1823. So I took the exact same code and added it to the TextBox.Leave event handler. And the weirdest thing happened: instead of the variable est being populated with 1822.60 after the parse, it gets set to -1! What the...?
Debugging the handler shows that the value goes into the parser correctly, and if I do the parsing manually via the Immediate window, it parses correctly, but when I let the code do it, it invariably gets set to -1. What's even weirder is that any number gets parsed as -1, not just decimals, and any non-number gets parsed as 0 (which is correct).
Has anybody else ever run into this before? I tried moving the code to the TextBox.LostFocus event instead, but with the same results. I have no idea what in the heck is going on, and obviously there are workarounds galore for this, but it just makes no sense whatsoever.
EDIT: Here's the full event handler (current behavior for which is to put -1 in the TextBox):
Private Sub txtEstimateAmount_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtEstimateAmount.Leave
' Take any dollars-and-cents amount and round to the nearest dollar
Dim est As Decimal

View 10 RepliesHave a project which, in one place, has a form with a number of textboxes on it to receive user input. My intention is that, when user tabs out of one box into the next in the sequence, a checking subroutine is called via the textbox.lostfocus event. When I run the app, which this procedure is called by tabbing out of, say, txtTitle without entering any data, I get the Msgbox message, but it refers to the next textbox (txtFName).
It would appear that the focus moves into the next textbox before the lostfocus event is dealt with. Consequently, when the Msgbox opens, it takes the focus away from the next textbox and fires its lostfocus even, which is processed. OK-ing the warning here causes the initial lostfocus event to be processed and the Msgbox shows again. Exiting the sub for the second time leaves the focus in the second textbox. If I then use the mouse to move the focus back to the first box, I fire yet another lostfocus event for the second textbox, etc, etc
How can I trap the lostfocus event and deal with it BEFORE the focus moves into a subsequent control?

View 5 RepliesI have a richtextbox which has CSV values in each line. Whenever a line is inserted, after pressing a command button the program lets the user know how many categories each line has.
Example:
Line1: a,b,c,d,e
Line2: x,y,z
Pressing the command button would say: Line1: 6 categories, Line2: 3 categories. This works fine, except from when I want a line to NOT contain any categories.
[Code]...
I understand that VB recognizes the vbCrlf on Line2 as a char, hence a 'category', hence the line is not empty. But what happens when I want to consider a line as empty (ie Line2:0 categories)? Should I go with something like if txt.line(i).text = vbcrlf then...? This solution seems kind of like bypassing the problem instead of actually solving it.. Or maybe it's just me?

View 1 RepliesSo I have a LostFocus handler for my TextBox, and it gets called whenever I press "m", "o", or "-". Why is that? [Code] Is all that's there. I thought that I might have access keys or something interfering, but I would have to be pressing Alt, "-" wouldn't work, and there's also the fact that I have no access keys on the form. What's happening?
