Focus Moves To Next Textbox When Any Text Entered
Oct 22, 2010
I'm working on an application to write reports for the work I do. I have a Grid filled with Textboxes inside a Scrollviewer to input data for the report. I am using the arrow keys to navigate around the grid. The focus moves to the expected Textbox when the arrow keys are pressed but if I press any other key it is immediately followed by a Tab to the next Textbox. Even a Tab is followed by another Tab. Following is the code I use for the navigation.
Private Sub svReportPage_KeyUp(ByVal sender As System.Object, ByVal e As System.Windows.Input.KeyEventArgs) Handles svReportPage.KeyUp
Dim focusDirection As FocusNavigationDirection
If e.Key = Key.Right Then focusDirection = FocusNavigationDirection.Right
If e.Key = Key.Left Then focusDirection = FocusNavigationDirection.Left

I have a few instances of a user control that has just a TextBox to search for items. The cursor is in one uc TextBox but the text I type appears in another uc TextBox. How can this be possible. Notice the cursor in model number, but the text is in upc.
Code:
Private Sub TxtScan_KeyDown(ByVal sender As Object, ByVal e As KeyEventArgs) Handles TxtScan.KeyDown
'When typing in the model number uc I see that the sender
'is the txtbox is the one in the UPC user control.
End Sub

I need to work with multiline textboxes. I am currently developing a web application that was started by someone else. The only problem I have is the text in my multiline textboxes is going to the next line before it needs to. I have played around with settings, removed the textboxes and added them back, and I am still having the same problem. When typing in the textboxes, the text moves to the next line after pressing the space bar.

In my keydown event handler, I am trapping when an ENTER is pressed and i want to advance to the next tab stop as is it was a TAB presses.I am currently using "SendKeys("{TAB"})" and this works but it is a sloppy way to do buisness, as there may be some typeahead keystrokes in the keyboard buffer.
I have also tried going through the controls collection off the form object, but it is too complicated as i am using containers within containers.Another consideration that TAB processing must be taking into consideration is "what if the tabindex is equal to the current tab stop? what if the next tab stop has tabstop=FALSE or is not enabled or not visible.The sendkeys approach handles all these issues but is a dirty approach and has keyboard buffer event processing quirks.There must be a method off some object somewhere that simply moves the focus to the next tabstop candidate.

I'm chasing code that is going to allow me to have multiple text boxes on my form, but when the form is first opened, it will only display one textbox. Once data is entered into said text box, i want it to display the next textbox, and so on. Is there a way to have these hidden?

I am working in VB 2008 and I have a textbox on a form that is used to enter a parcel number. I can enter the number in a 15 character string such as 12345678...... and it works just fine. The parcel number in real life contains dashes to make it easier to read, decipher, etc. so it looks like 12-3-45-67....... Under the textchanged subroutine for the textbox I have a case statement set up that checks the length of the parcel number as it is entered and inserts the dash accordingly.

And it works fine, but I'd like to do the same thing on the click event. Here's my problem. The same code of enter event in text box, apparently doesn't work on mouse down and mose up.

I'm using the code below to select the text within my textbox during the mousedown event. It works great when the HeaderChanged sub is not called. The problem is, the HeaderChanged sub will always be called on the textbox's focus event.If the user clicks the far right portion of the textbox the whole text value will be selected (like it should), but if the user clicks near the left side of the textbox only a portion of the text will be selected.

There are 2 non-modal windows displayed- 1]Form1 contains a Listbox with a list of forms 2]Form2 is the form which is selected in that list Form2 consists of a Maskedtextbox T1. In the Leave event of T1, the validation of text is done. If the data is invalid, a suitable Messagebox is displayed and Focus is set back to that Maskedtextbox (T1.Focus()).Now, if I enter any invalid data and click on the Listbox in Form1, the following things happen:
1]T1 Leave event is entered, focus being on the Listbox
2]Invalid data message box is displayed
3]Focus is set to T1(T1.Focus()) of Form2
4]After End of event, T1 Leave event is again entered. And now, Focus has changed back again to the Listbox.
5]Again Messagebox is displayed and T1.Focus() is done
The issue is, after step 3(focus set to T1), the focus is reset to the Listbox in Form1. Hence Leave event is entered twice and messagebox is displayed twice.

I have two forms, one has a textbox on it the other also has textbox on it. Form1's textbox is the source for text found. form2's textbox contains the search criteria.
This the code that I quickly bashed out to do a find functionality of a textbox. The problem is the last line of code. If I use the last line of code the the Source Form.s textbox is highlighted however if the Source Form is Maximised then the Find form will be hehind the Source Form. I don't want that to happen. Secondondly if I dont use the last line of code then the the text isn't seleceted at all.
Private Sub DoFind(ByVal xControl As Control)
Dim x As Boolean = TypeOf xControl Is TextBox
Static Dim lastfoundPosition As Integer = 1

Hi, I'm working on a program that reads text entered into a textbox and creates a list of items by separating entries by commas. Everything is working fine, except, because I am using an array to store the items in the list, I have a limited number of entries. This is only a problem because, as it is written currently, each comma counts as an individual entry. Therefore, users can enter ",,," for example, and it would use up 3 places in the array.
I'm looking for a way to check to make sure there is text after the comma before adding an entry. I've attempted to use the .substring command to check the character after, which works until it gets to the last character. Because there is no character after that, it will give an error.
Here is my code for extra clarity:
Public Class frmMain
Dim intCounter As Integer 'Stores the # of commas in the string
Dim Messages(49) As MessageProperties
