Placing Multiple Pictureboxes To Different Location By Using Keypress Event?
Dec 19, 2011I have this code. credits to jmchiney. My goal is when I press a certain key, the picturebox corresponding to that key should be moved to a certain location. Exactly like in the text twist game.
I have a code running and doing what I want but It is only applicable for single letter. For example the word alabama. all letters without duplicates are placed properly but for letter a, only one letter a is being accepted and moved. that goes for all letters.
Here is the
Dim pb As New PictureBox
Select Case (e.KeyChar)
Case CChar(letterPicbox1.Tag)
[Code].....
Another one. when a certain letter is already placed to the location I set and once I press again the same letter, the location changes. What I want is when I already gave pictureboxA a location and then I press "a" which correspond to pictureboxA again it should be stationary and check if there are other letter "a" in my pictureboxes and move the next detected letter "a" to the next position. Like i said. just like text twist game.

C# - Use KeyPress Event Logic For Textbox.Text Assignment?
May 31, 2011I have the below code on the KeyPress event of a textbox howver a need has now come in meaning I have to do myTextbox.Text = "A input string"
Private Sub ChequeAmountKeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtChequeAmount.KeyPress
Dim tb As TextBox = sender
If (e.KeyChar = "." AndAlso tb.Text.Length = 0) Then
e.Handled = True
[Code]...
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.
Forms :: Multi-line Textbox And KeyPress Event Unusual Behavior?
Aug 13, 2010I 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.
Select Case
Case Keys.Right
tbRight.Focus()
[code]....
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"

KeyPress - Beep And Loops - Occur Multiple Times During The Execution Of A Program
Aug 10, 2011I've written a keydown event that needs to occur multiple times during the execution of a program, and it needs to play a sound each time. The first time the keydown event is triggered, the sound plays without a hitch. However, the second time (and all subsequent times) the keydown event is triggered, a system beep accompanies the sound. I'm using Studio Express '10 and I've already integrated e.SuppressKeyPress into my code:

MemoryStream Truncating Input - Replace All Instances Of A Certain Character With A Unicode Character?
Jul 10, 2009I am working on a sub that essentially needs to open a text file, and replace all instances of a certain character with a unicode character. I'm trying to do this by reading the original text file byte by byte, converting it to a character, and then either adding that character to a memory stream or writing the unicode character to the memory stream. Then I'm saving the memory stream to the original file.

View 2 RepliesFind / Replace Multiple Text In Rich Textbox?
Apr 12, 2012I am trying to open up a text file that contains some text. I have 3 text boxes on my screen. What I need to figure out is how to replace multiple words (1 in each textbox) with text it finds in the txt file.
I can do this by using the single find / replace feature but I'm trying to be able to fill out the 3 textboxes and then click my find / replace button to have my Regex find each predefined word and replace it with what is in the text boxes.
Here is my code to get the find / replace one word at time feature. I've tinkered with this to just add more variables to my Regex but it doesn't seem to work.

Replace Multiple Selections In Listbox With Textbox.text?
Oct 23, 2009I have code that works to place two items in listbox into two textboxes when selected (multiple select extended).
Private Sub lstOutput_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstOutput.SelectedIndexChanged
Dim i As Integer = lstOutput.SelectedIndex
[code]....
I need also to be able to modify the data in the textboxes and replace the lines in the listbox. The reverse code doesn't work properly, it only replaces the first selected item. The "lstOutput.Items(i + 1)" appears not to lead to the second selected item.
Dim i As Integer = lstOutput.SelectedIndex
lstOutput.SelectedItem = lstOutput.Items(i + 1)
lstOutput.Items(i) = txtName.Text
lstOutput.Items(i + 1) = txtPhone.Text
I have scoured the web for ways to manipulate the selected index/indices, with no success.
