I have two issues. The first is that I want to make a textbox scrolling similar to how credits scroll. I don't want it to move on the form, just to scrolling the text down a line/pixel. I thought I could do it with the "Lines" element, but I'm not exactly sure how to execute it.
The other problem is with my flash screen. Right now I have it set so when a button is click, it goes onto the main form. I don't want to use the button but rather have it so if Enter is pressed at any time, it'll go to the main form. All the solutions I've tried to use involve the "e.Keycode" code, but for some reason its unavailable.
how can I detect if press Enter in the Textbox Change event and not in Textbox Keypress?
View 3 RepliesI have a simple question regarding the KeyPress event. I'm trying to make it to where my TextBox on my form can only accept numbers 0-9, backspace and '.' /without quotes. I've successfully got it to accept numbers 0-9, accept backspace, I'm just wondering - what line do I add so that it can accept periods as well?
Here's my

View 9 RepliesI 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

I have been out of VB since VB 6, but am back into it to write a basic app. I have created a listbox and am able to add data to it from a textbox via a command button. However, I want to give the user the option to simply press the enter key after they have entered the info the textbox, instead of clicking on the command button. I tried calling the function the command button is using from the "ENTER" event on the textbox, but all that does is execute the function when I click on the textbox? I'm sure this is very simple. What am I missing?
View 5 RepliesI'm building a Dialog in Winforms. It's got the two OK and Cancel buttons that are there when you create it, which is what I want. In this dialog I also have a TextBox and a Sub (coding in VB.NET) that handles its KeyPress event. I need stuff to happen when the 'Enter' key is pressed. Now, I've done such KeyPress handling times and times again. This situation, however, is different, because as soon as 'Enter' key is pressed, the dialog automatically assumes you're pressing the 'OK' button, returns a result and closes.
In both the Designer and the actual form when running the application, the OK button is highlight, which means is has some kind of a focus (for the lack of a better term) at all times. How can I disable this feature of a dialog? When I debug my code, pressing enter does not even get to the sub handling the KeyPress event. It simply closes the dialog and returns the result, therefore I can't really step through the code and see what happens behind the scenes. To restate the question, how can I disable this functionality?
I have a problem opening a new form with ShowDialog when pressing the AcceptButton on the first form. Consider the following example

I have a Telerik Radgrid containing all the valid usernames and passwords that can be used to unlock functionnalities on my web page. The password is encrypted, so you have to click the row to decrypt and show the actual password. All usernames and passwords can be changed by an admin When the admin presses [ENTER] to submit the new username/password combination (instead of pressing the submit button), the new combination is actually submitted (which is fine).

I know you can validate textbox text by using the keypress events. But the form i'm working on has multiple groupboxes with multiple textboxes. So rather than having a sub routine to validate every groupbox, i was wanting to have just the one keypress event that handles the textbox entries, and depending on the textbox calls a specific validation routine.[code]

I want to validate all the characters. How I can make the event keypress validate all characters in a text box?
I have a TextBox which Is allowed only to read certain characters. I use KeyPress event to handle this event. I understand that The KeyPress event does not handle the pressing of the DELETE key on the keyboard. I do not want the user to be able to delete characters in the txtbox by using the DELETE key, I want the user only to be able to use the backspace key. I am writing this code in Visual Basic 2005. The following code appears to work in handling the DELETE key, but I am concerned that I might get bitten by the fact that I am using KeyDown and KeyPress on the same control (txtSource).
private sub txtSource_KeyDown(byval sender as object, byval e as KeyEventArgs) handles txtSource.KeyDown

This input string could contain a format that I do not want and whilst the keypress event caters for the need when the user is typing I need to handle it in the case of a text assignment.I thought firing the keypress event after I assigned the text property but I dont think that will offer what I want.

View 2 RepliesI have several multi-line textboxes that I want to lose focus (i.e. when the user presses the right arrow key) but the control wil not relinquish the focus.Simply put, I first verify if the selection start is at the end of the text, if it is, and the user presses the arrow key, it should move to the next textbox. some debug.print code placed in strategic locations indicates that the target textbox gets focus and immediately loses it and the source textbox gains focus once again. Essentially not allowing the textbox to lose focus.

Case Keys.Right
tbRight.Focus()

After changing the source textbox multi-line property to false, it behaves as expected. Is this a "feature" .. surely I don't have to resort to "SendKeys"
