View 2 RepliesOn my login form I have a username text box and a password text box...
The TxtUsername text box is preset with the following:
Text: Username
Colour: Gray
Here is the code for the TxtUsername (on click):
Private Sub TxtUsername_Click
TxtUsername.Text = ""
TxtUsername.ForeColor = Color.Black
(So it's like the facebook login if your familiar with it)When user clicks the text box, the gray text already inside gets erased and user is able to type with black text.The problem is that even when the user has typed in the box, every time you click the text box the text still gets erased....It's like the code should be something like If TxtUsername.Text = Anything but "Username" then dont change it to ""
I have a text box labled QTY, which feeds the QTY column on a datatable. the table then is ran through a function that takes the data and converts it to a string which my production machine can read. My problem is this, and its probably really simple (these problems usually are) how to i force the user to use a specific type of input on the txtbox so they would have to put the QTY in the format of 01 02 03 etc etc, i have it set to default to 00 but i want to force the user to haver to input 2 chars.

For a class project I am thinking of doing a Spelling Bee game. I would like to have a button that will place the word in a sentence, and a button that will give the definition. Are there .txt dictionaries out there with this information? I've checked a few places like WordNet but I didn't see a dictionary that also includes sentence info. My other concern is using custom classes. I don't have a lot of experience creating classes, and I really want to become more familiar with them, so it is important that I integrate them into this project. What would be a logical way using classes in this project? Maybe a 'word' class?
View 1 Replies am trying trying to write some code for a ComboBox that does the following:
1. Allow the user to enter text into the combo box to type entries contained in the list source.
2. Enable autocomplete to assist the user in selecting entries in the list source, both from dropped down state and non dropped down state.
3. Restrict the user from typing an entry that doesn't exist in the list source.
My requirements are:
1. The ComboBox must run some code after a selection has been made or the user has finished typing an entry (not after the focus has been moved to another control)
2. The code must only run once after the user has made a selection from the combobox or has finished typing an entry
The problem: To achieve the above functionality, I had to run code on numerous event's. Sureley there is a better way, here are the events and the reason for the code:
SelectedIndexChanged:This is the code that is run when the user makes a selection. No Mystery here
KeyDown:
Must Run
If e.KeyCode = Keys.Return Then
ComboBox1_SelectedIndexChanged(Nothing, Nothing)
End If

Well I've been working on a web designer and I wanted to be able to color different keywords and strings enclosed in quotes. Now I've been able to color the keywords but every time I try to color a string in quotes it colors the from the beginning of the document to the end of the quoted string. I've tried looking at samples and apply those methods to the code but it still colors all the text in front of the quoted string as well.This is the sub I'm using to color the text.

I need something tje user can type in data to such a parts QTY cost etc. There are no predefined parts list so the user can enter any part name/Number and there is no limit to amount of parts that can be entered.
Does anyone have any idea what might be useful. It was thinks of a listview bu i can't see that you can type into that. I cant use comboboxs because there are no predefined list and i know there is some way to generate text at runtime (i think) but i don't know how to do it and i would prefer a clearer approach.
i want to know how to type cast to user defined type in vb.net.I have a mark object which contains student id , subject name,subject id and mark. I have to read the subject id from a combo box and read corresponding mark value from it to a text box.
