The code I am having problems with is supposed to take a ID number and load the information from several different tables into a game object, then return the object. When it tries to load the data into the object I get an error saying there is no data in the row or column. [code]
View 2 RepliesThe program is currently trying to pull information from three different database tables and compiling the information onto one screen, to do this i am using three different connections and a function to handle the data at each stage. The issue is as my code hits PageLoadStage of "2" and runs the QueryDatabase() Function i am encountering an error of: "OleDB exception unhandled: No value given for one or more of the required parameters." This occurs on line 15 of the first code snippet. Can anyone explain this and/or identify any code issues if that is the cause.

what i need to do is to get information from 2 tables and show it to the listview. for example, i want to get the surname, first name and middle name from the student_info table and the Payment_Status from the accounting_system. i don't want to show the information that is already on the accounting system that has 'Paid' on the Payment_Status.[code]but the listview only showed the first data on the database

From rows In db.Locations, clientRow In db.Clients, stateData In db.Ref_States
Where rows.State = stateData.ID
Select ClientName = clientRow.Name, rows.ID, rows.Address1, rows.Address2, rows.City, StateName = stateData.Name, ShortStateName = stateData.ShortName, rows.ZipCode Order By Address1
That's what I have and it is very wrong. Everything shows up, but the data displays incorrectly, displays more rows than exist.

I have to tables into my SQL Server 2008 database
1st table: tblUser (user_id, user_name, user_photo);
2nd table: tblAccess (id, user_id, status_access);
I need to permit access or denied access using this 2 tables....
The problem is: When the user type a 'user_id' in textbox, the application go to table tblAccess and verify if the status_access is true or false.... if is false, the application show a msgbox saing "Access denieded"... when status_access is true the application go to table 'tblUser' and get user_name, user_photo and show the user photo to the picturebox, show the user name to the labeltext and a message box saying : access permited...

Is it possible to send information to a USB Video game controller in VB.Net? The kind of information I want to send to it is information causing the device to think that a button is pressed on the controller when it really is not. Or even better, is it possible to make a USB wire that connects to your computer and another USB port on something such a computer and send information that a video game controller would send to the other computer or whatever? Basically what I want to do is emulate a guitar hero controller sending the data of the buttons being pressed to an xbox 360 console.

View 3 RepliesI 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:

View 1 RepliesI've tried to implement this highscore saving feature, so that when my application closes, the highscore saves within the my.settings storage function, and when my program loads up again, the same highscore loads up from this file. atm, it works ONLY within the application (I can close forms and it's still there, but if i end the program it resets to 0 next time it's loaded).it's basically 2 lines of code..1 for saving and 1 for loading..is this the best way to save a highscore for a game? I was initially thinking of making a database and linking it to that, but apprantly it's easier with the My.settings. even thought of using stremawriter but it's more uneccessary work over my.settings.[code]

I've found how to retreive multiple tables like,
Da = New OleDb.OleDbDataAdapter("Select groups.groupid,groups.userid,lots.groupid,lots.lotid from groups inner join lots on groups.groupid=lots.groupid order by groups.groupid asc", DB) But the only way I have found to update is to use seperate Update commands for each table.
