View 8 RepliesI want that it is not possible to type anything in a textbox, but i do need to place something in it. This is my temporary
Private Sub textbox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles textbox1.TextChanged
If textbox1.Text = Nothing Then
Else
textbox1.Text = Nothing
End If
End Sub
But in this way I cant place anything either. I want only that it is not possible to type something in it.
how do you restrict letters from being entered into a textbox?I know it invloves textbox_TextChanged but i don't know who to do so.
Edit: I figured out that Letters(25) = (a b c etc...) can be used but how to not enter the letter? Uhm.. Like, the user enters "a" and the program recognizes it using an IF statement. How will it NOT enter the letter into the textbox?
OK, SO i have this program that outputs all the servers on a specific game. It outputs it to a text file. HOWEVER, There is a lot of annoying spaces. This is kind of hard to explain, so ill try to explain it. This is what The text file looks like. [Code]
As you can see, they have these annoying spaces. What I want to do: 1. Get rid of the spaces, BUT KEEP A SPACE BETWEEN THE IP AND THE PORT. 2. After the spaces that are bad are gone, I want the program to output each single IP AND port To its own text Box. It doesn't matter is the textbox of the IP and Port are separated, It can just be one textbox with the IP and port, with a space between them. Thats about it. I have the GUI done, and the rest of the programming, all I need now is this. Reformat without spaces > output each separate line of text to a separate textbox > TYTYTYTY
PS, is there a way for VB to send a command to the command prompt? Say, I wanted it to open a CMD box and send ipconfig into that box, what would that be?
I just changed a control on a form from a masked textbox to a normal textbox because I wrote my own code to validate the data. I'm trying to clear the leading spaces that were created for this column in an Access database using the LTrim function and it doesn't work for some reason. The column is " :30" in the table and when I LTrim it and save the changes, it's still " :30" , not ":30". Is that leading entry not a space character?
View 4 RepliesI need to write a program in VB 2008 express that takes an user entry from a textbox and strips out all the spaces, changes it to either all upper case or all lower case then checks to see if it is a palindrome. I must also include a loop structure and a decision structure. I have seen bits and pieces of code but I do not really know how to put them together. Basically I need it from the button click to the end. ?

I want my user to only be able to open files in the initial directory that I set on OpenFileDialog. I have googled a bit and found you cannot restrict, but that was information from a few years ago and I'm not sure what version. Has this control changed at all in VS 2008?
My application is handling it okay if the user does navigate out, but it would be more concise if I could prevent him from doing so in the first place. And the fact that I have found others who wanted to do this also, makes me think it might be a nice property to have built in.
Not really sure if the title is fitting but couldnt figure out a better one.
