Capture [Enter] Key Event

Apr 29, 2010

Ok, 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?

Works ok for single line. Does however insert a blank line above current text and cursor is at start of second line containing text.

ENTER Keypress Event Only Handled Once?

Jun 22, 2010

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.

How To Handle Enter KeyPress Event

Jul 19, 2010

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.

TextChanged Event - What Format Needed To Enter The Date?

Feb 9, 2009

I'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 :

[code]...

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?

Override An Event - TextChanged Event Not To Be Triggered When The CellClick Event Occurs?

Jul 20, 2010

I'm trying to validate a few things in a form I'm building. It has a datagrid with clients info (taken from an access database) and a few textboxes where the user can type some search criteria. The thing is that those same textboxes are used to add new clients to the database and to modify a client's information if one from the datagrid is selected, so I made it that the buttons to insert and modify clients are disabled on load and thenevery time the text on a textbox changes ("TextChanged" event) they become enabled. So far so good. But then I wanted to make it so when a client from the datagrid is selected both buttons become disabled again until the text on a textbox changes (to make sure they're adding a different client and not the same one that was
selected).

I tried using the CellClick event from the datagrid to disable the buttons, but since every time a client is selected from the datagrid the info is shown on the textboxes, this triggers the TextChanged event too, and the buttons become available.So, is there a way I can tell the TextChanged event not to be triggered when the CellClick event occurs?

[Timer] Trigger Event Manually - User Must Wait For A Minute Before The Event Is Triggered

Feb 12, 2010

Eg. ""vb.net" timer event trigger on purpose". This application is meant to run at all times to download a web page every minute. To avoid freezing the UI, I read that the best solution is to move the code from a While/Sleep loop to a Timer that will be triggered every minute. The problem I have, is that the user must wait for a minute before the event is triggered:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Timer1.Interval = 60000
Timer1.Enabled = True

[CODE]...

Is it possible to force this event to occur instead of waiting for it?

Resize Event Triggered Before Load Event

Jul 18, 2012

Following on from my post yesterday (how to anchor buttons/controls to various sides of the current form when the form is resized) I have run into another problem. I am setting the width of my datagrid to be 80% of the form width on a 'form resize' event with 10% of the width at either side so it remains centred in whatever size window is available. This works fine. (mydatagrid.width = me.width/5*4)

I then decided to dynamically set the width of the 2 columns in the datagrid each to 50% of the width of the datagrid. Again, this sub is called in the 'form resize' event. This fails because the datagrid hasn't loaded the data from my sql database when the first 'resize' event is triggered. I did a bit of testing (by placing a simple msgbox statement into the resize event and the load event) and it seems the 'resize' event is triggered three times before the form's load event.

how do I stop the resize event triggering when the form loads (or at least make the load event trigger first).
