View 1 RepliesIm building a, lets say kiosk, that has only one form of input and that is a keyboard. I've got an up/down/left/right arrows and the enter button. I have a form that needs to have hundreds of buttons. I've arranged all my buttons in a giant grid and want the user to use the arrows to navigate through the buttons. The button that is 'highlighted', lack of a better term, has different colors so we know which button we currently are on. So when the user hits the down arrow the button below the current button gets highlighted. My issue is that when the user hits the left and right arrows the 'cursor' doesnt move left and right it moves up and down.
The left and right arrows follow the tabindex sequence.

View 1 RepliesI am having trouble removing a line from a text file. When I click on the button in order to remove the line it gives me an error that access to the file is not possible. Now I assume that the file is in use during me wanting to change it and therefore cant save it while it is loaded in ht application. I have tried a few things but cant seem to get it to work.Essentially what it does is that I have another dialog that a used can add data, the data is then written to the file FilingLocations.txt and then it saves it and loads it again. But once the line is no longer needed I would like to have the option to remove the line agaise.
Here is the code:
Private Sub cmdRemoveLocation_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdRemoveLocation.Click

I'm having a little trouble deleting multiple lines for a listbox. I know how to remove a single line, which is this: [code]If I change the value for IndexOf to SelectedItems, I get an error stating that -1 is not valid for index.I am guessing this needs to be done using an integer array and a for each but I don't know how to do that. I really never bothered to look much into arrays.

I'm using text files as an array to store and remove information, however I do not know know how to adapt this code so the line I search for is removed.
My text files are set up as such:
021,Donovan,56 Eynesford Crescent,Bexleyheath,CT5 1TR,09/08/1967,13 March 2012,Bronze
062,Fredrikson,6 Freil Road,Gravesend,CT9 1RB,12/06/1995,13 March 2012,Silver
So I can search and locate the ID, in these cases 021 or 062, but I want to be able to remove the line I want, once it's been found.
I was playing around with my duplicated code to try to do the the following:

give me a working regex expression (C#/VB.NET) that can remove single line comments from a SQL statement ?I mean these comments:
-- This is a comment
not those
/* this is a comment */
because I already can handle the star comments.I have a made a little parser that removes those comments when they are at the start of the line, but they can also be somewhere after code or worse, in a SQL-string 'hello --Test -- World' Those comments should also be removed (except those in a SQL string of course - if possible).Surprisingly I didn't got the regex working. I would have assumed the star comments to be more difficult, but actually, they aren't.
As per request, here my code to remove /**/-style comments (In order to have it ignore SQL-Style strings, you have to subsitute strings with a uniqueidentifier (i used 4 concated), then apply the comment-removal, then apply string-backsubstitution.
static string RemoveCstyleComments(string strInput)
{
string strPattern = @"/[*][wds]+[*]/";
//strPattern = @"/*.*?*/"; // Doesn't work

I know there's ton of examples on the forum but i could not get it to work the way i want.
Sample CSV :-
Unused,172.22.21.2,SD103001
Unused,172.22.21.3,SD103002
Unused,172.22.21.4,SD103003
And what i wana do is change the Unused to Used so basically once this is done it will look like.
Used,172.22.21.2,SD103001
Unused,172.22.21.3,SD103002
Unused,172.22.21.4,SD103003
One thing to mention is i dont want to loop through the whole file and change all the Unused to Used. So basically software fires up opens the file and looks for Unused and changes it to Used and does the rest of the function and shuts down. Next time the software is fired up it goes through and does the same thing.
