Tell The User That Their Username Already Exists In The Game?
Jun 12, 2011
I am having a problem that dtAsia.rows.count>0 doesn't count at all. All I want to do is tell the user that their username already exists in the game but I'm having a bad time now because for example: I entered a valid username and its success... I entered an invalid username and got the CATCH part of this code.. So if i entered a valid username again. I still got the CATCH part of the code until the end even if I enter valid or invalid username still got the CATCH part.
If (dtAsia.Rows.Count > 0) Then ' wont work
MsgBox("Username: " & Trim(txtUsername.Text) & " is already exist.", MsgBoxStyle.OkOnly, "Message :")
[Code].....

I am trying to get my program to identify the user's screen name and input it into a file path. I use vb2008, and here is what i have: Dim strUser As String = My.User.Name This works but retrieve the info in this format: ('Computer Name'/'Username') Is there any way to code the program to get rid of the first part of My.User.Name (the 'Computer Name' part)? Or is there another way that i don't know of where i can identify the users username.

I have this MySQL Query glitch in my VB.NET program. Here is the query in VB.NET:
"SELECT Points FROM user WHERE Username = '" & UsernameText.Text & "';"
It will select the points column from the user table from the Username they entered. When I deploy this it will set the value for points to 0 on their account. I'm not even inserting anything in.

How do you save settings for a DataGridView? I'm making a game, and I want the user to be able to save their settings in a datagridview, and have it opened when he/she looks at the records form again.
I know this is what you do with a textbox, lets say:
My.Settings.Username = TextBox1.Text
My.Settings.Save()
But how would do that with a DataGrid View?

I have a login form that I made. The user enters a username in textbox1 and then enters a password in textbox2. The user then hits the submit button (button2) and from there it works beautifully. The problem is, I would also like the user to be able to hit the "enter" key after they fill out the password textbox (textbox2) and have it be like they pressed the submit button. When the user hits enter right now, the form hides.

I've made a small game that lets the user move a picturebox around with arrowkeys. The monster picturebox is moved towards the player and keeps growing while you are "alive". If it touches you, you lose.
How to improve my code. Im the worst ever at OOP programming. The main reason is i dont understand how i can pass variables between subs/functions e.t.c. I've read up on overloading operators but i dont feel that i can grasp it. If someone has any comments or any simple examples on improving my ability i wouldnt mind hearing them ^^
This is what i have now. Attached project (with "graphics") without .exe files and all code is also below. Also an image of what it looks like below.

i've created a hangman game (Fully working) but since you can only "play" with one phrase (10 letters) it gets boring fast. Basic the current game works by on form load i define the slots (10 string which each hold a letter) and give them there letter. then the user type in a text box and if the textbox = any of the slots then the lbl repasenting that slots changes its text from "_" to the letter.
Anyway what I would like the button to do is when the user presses the start button a random number is generated. The program then looks into a textfile and based on which number is generated it takes a certain line (10 characters per line in a phrase) , moves them into the slots and the game starts. Is that possible to code or it too complicated. The textfile will be in the applications folder (words.txt).

I am creating a user tool for a game I am playing (NOT a hacking tool, it simply shows information about my own character). I have a template of what I need to do with the data I recieve, here is the code, it is coded in PHP
function decode_style($r) {
//get gender
$gender_array = array('Male', 'Female', 'Male 2','Female 2','Male 3', 'Female 3');
$style['Gender'] = $gender_array[round($r / hexdec(4000000))];
//GET AURA
[CODE]...
Ok, I understand PHP a bit (As you know one programming language you can understand just about any) and this is what I have created from this
Dim Style As Decimal
Dim Rank, RRank As Decimal
Dim Gender, RGender As Decimal
Dim Aura, RAura As Decimal
[CODE]...
As you can see, it is receiving a single piece of data from a remote SQL server, I then need to run this data through the above calculations (Seen in the PHP file) although the answers I'm getting are incorrect.
Here are some simple instructions I got in what goes on between values:
gender :
