View 2 RepliesOk, so this is VERY simple to do IF I was working with a regular Textbox control. But of course, Microsoft does not have an "AcceptsReturn" property for a MaskedTextbox Control.
So, if the user finishes typing in the MaskedTextbox control and hits the [Enter] key.... How do I capture that key stroke with this type of control? Also, what if this MaskedTextbox is on a UserControl, not a regular WindowsForm?
create an Enter event.
Private Sub txtField_KeyPress(ByVal Index As Integer, ByVal KeyAscii As Integer)
Dim vbkeyreturn As ValidationConstraints
If KeyAscii = vbKeyReturn Then
MsgBox("hello")
End If
how I can use the Enter key on my keyboard as an event. So when the user click the enter key then it will do some code like an event handler.
View 2 RepliesWhen the enter key is pressed, I would like to have <br /> added to the end of a each line in multiline textbox then allow me to type next line. Then repeat for each line.
using:
Private Sub TextBox_Body_TextChanged(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox_Body.KeyDown
If e.KeyCode = Keys.Enter Then
Works ok for single line. Does however insert a blank line above current text and cursor is at start of second line containing text.

3. another object named "penbutton" to change it's text, that u can see on the picture to "write"..
4. originally the book will have the text "Start" on it

I am trying to add to items to a combobox by using the "enter" key. It does work when I add the first item, but if I manually clear the box and add another items it does not get added to the list.
(1) I click in the combobox and type "hello" and press the "enter" key
(2) I click on the dropdown arrow and see that "hello" is in the list
(3) I select "hello" in the box and erase it, item is still in the list
(4) I type "goodbye" in the box and press the "enter" key
(5) "hello" is still in the list but "goodbye" is not
Here is the code:
Private Sub CopyrightCombo_Keypress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles CopyrightCombo.KeyPress
If e.KeyChar = Microsoft.VisualBasic.ChrW(Keys.Return) Then
[code].....
if I comment the if/end if line and type "hello" the items added to the combobox list are: "h", "he", "hel", "hell", "hello" wich makes sens since the add items is run on every keypress? I know that my commands for adding items is good, I know that my keypress event is handled properly but not when I specify using the "enter" key.
I am using the Event Handler below for the Enter Key Press Event, it is running when ever any of the keys is pressed. This is not so much a problem when the app. is running, unnecessary yes. It is giving me problems when ever I am Debugging using Breakpoints. How can I change the Handler so it only runs when the Enter Key is Pressed, doing away with the If statement?
Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Me.KeyPress
If e.KeyChar = Chr(Keys.Enter) Then
'Different code blocks will run here depending on what
'TextBox or Label is selected.
End If
End Sub

View 1 RepliesI have created VBA form in which I have list box and few buttons. I want to handle the enter key event when some one has selected some item from list box and pressed enter. If I can make some specific button click event default for enter key then also fine.
View 4 RepliesI'm not sure if this is possible, but if someone could explain as to why it might be happening.I have a form which has some textboxes: txtDateFrom txtDateTo Where the user would enter the date from and date to that he would like to search for. I've given these textboxes default values in their properties: e.g. txtDateFrom's text is 'Date From' and txtDateTo is 'Date To' . I've then added a onclick event to each of these text boxes informing them what format they need to enter the date :

This method however seems to be invoked as soon as the form is opened, does putting a default value for a textbox invoke textchanged? surely not?

How Do I Make Button.click Event Perform both the enter and period(del) keys on the numeric keypad? [Code] Case Keys.Enter and Case Keys.Separator do not work. Nor does anything like Keys.OEMPeriod for the period(del) key. I've also tried calling the enter key in a KeyPress event etc. But to no avail. Any ideas?
