Parameters - User Login Before Program Loads
Nov 30, 2010
I am writing a program where the user has to log in before the program loads. Right now I have all the users and passwords hard coded into the program. Recently I have written a Oracle function that the username and password is sent to the DB and a yes or no is sent back after comparing the passwords. I am getting the correct response back and it will display in a label (I tried it to make sure the response is correct). The problem I am having is that the program after receiving the response doesn't recognize the response so I always get an incorrect password error.
Below is my code:
empName = tbxUser.Text
passWord = tbxPassword.Text
dbConn.ConnectionString =
"Data Source=!!!!; User Id=!!!!; Password=!!!!"

How would I go about writing a program that would run before the user logs in to the system?The application would use a timer to start about 10 programs without the user needing to click either the application that starts the 10 programs or one of the 10 programs.
what I need it to do:
1. application needs to start before user logs in.
2. should use a timer to start 10 programs (with admin permission) successive after XX seconds.
3. should run the programs as if it's a shortcut, thus being able to add for example the -win parameter.
4. require a password to change it settings
The thing I really need to know is how to add a parameter to the file i want to execute. and how to set up the program propperly to run with administrator permissions before the user is logged in. (bassically I want the program to run as a service.)

I'm using Visual Basic Express 2010 and SQL Express 2008 in Windows XP. At first I couldn't add a datasource (the .mdf file for the database) because of a "Operating system error 32" which I seemed to have resolved by giving myself full permissions for .mdf file (by right clicking on the file and going into properties and then Security) and restarting the SQL SERVER (SQLEXPRESS) service. The dataset for the database is in my solution explorer but when I right click on a table adapter to add a query and attempt to open up the query builder, I get the error in the title above.

I have a simple web for that has a dropdown list and a button on the form.The dropdown list is bound to a table in my database and holds three values with idents between 1 and 3 (Weekly,Monthly, Please Select).I have set my datasource to pull back item 3 (Please Select) as the first item in the dropdown list to prompt the user to select an option. Items 1 & 2 have data assigned to them and this pulls back the relevent data for these options.
Here is my problem. I need to hide my button when the page loads until the user selects item 1 or 2 and would like the button to be hidden of option 3 is selected. I have tried to complete this in my page load event and the code for the dropdown list but i cannot seem to get this to work.
If IsNumeric(DropDownList1.SelectedValue) = 3 Then
btnAddAgendaTemplate.Visible = False
End If

basically i want to create a login to my program which uses the same username and password as windows login.I already know how to retrieve username and auto place it in the username box using
TextBox1.Text = Environment.UserName.ToString
i wondered is there an easy way to only allow access if the password matches up to their logon? i dont know about setting up databases but i dont think this option would work because each member of staff can personally choose their password.

I created a SQL DB named MainDB.mdf and a small VB 2010 application with some forms and datasets.Everything was working OK until i got a new computer and re-installed Visual Studio 2010 and SQL server 2010 on it. I copied my DB from the old to the new computer and also copied by VB 2010 project to it. I used Windows Authentication to connect to the DB in the old computer and also in the new one, i am using different Windows user account names though.
I was able to connect to the DB in the new computer in the Server Explorer section, i created a new connection string to the DB and i can seed there is data in the tables. When i run my VB 2010 application created in the old computer get error:
"Cannot open database "MainDB" requested by the login. The login failed. Login failed for user 'D630Admin'."
I need to get rid of that error and be able to add/mod/del data from my DB using my VB application as i used to.

I have a basic page which has fields that I read from the database and write to it. I would like to know where I should call the insert and read commands. I know about age_load but heard about page_loadcomplete.I noted that when the user refreshes the page, for some reason the sqldatasource loads the old data(before the write) even though new data has been loaded on the form.

I have been trying to solve this for 2 days now, every text book I own and google have been well and truely exhausted and I am still no closer to solving my problems.I have a login facility reading in user info from a main user file. This takes all info into a temp array and then splits usernames into a username file, passwords into a password file and a current score in a score file.
I have the login working fine and everything else in my program works as intended but touching up cosmetic aspects I want to add a Message box after login to say hello and display current score. This works great for the first name in the user file i.e - after login User1 welcome to the game. Your current score is 45 As intended.But the problem arises with any other users, my message comes out as
User2 welcome to the game. Your current score is 55 I do not understand where the random new lines are coming from. I have tried assigning the message as a variable and removing new line using

I have my program working that loads flash movies and games for my son to play offline. Some of the games have http links in them. Is there any way that still allows playing the game without launching a webpage request? I have no code for this part of the program because I don't know where to look. I think I am just looking on how to block requests for launching anything outside of the program, or catching the request while my program is running, but not quite sure what to do.

I am trying to write a program which loads a tiff image on picturebox. Then the user clicks somewhere on loaded image to set the starting x,y coordinates and clicks again to set the ending x,y point. Then clicks the run button and the starting and ending x,y points are written on label.
Just to test the program a loaded a tiff image that has a dimension of 75x75 pixels. When I click upperleft and downright corners of the image, the program outputs the coordinates as starting x,y as (103,89) and ending points as (170,157). The program outputs wrong coordinates becayse the image has 75 rows and 75 colums only. To me, it should have outputted starting point as (0,0) and ending points as (75,75).
Public Class Form1
Dim StartX, StartY, EndX, EndY As Int16
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

My problem is, I just finish creating a program, that loads a picture and description of a selection from a radio button.
Everything works on MY comp, but when i go to my lil sister comp and load the .exe file there, everything works too EXCEPT the image....the error is something along the line " C:documentspictures ame.jpg" not found.
My question is: how would I store the image to the program via another file or the program itself. so that when I "build" my program, I just need to run the .exe and lets say another file "for ex: .dll ", with all the images stored inside. And I dont know how to create and work with .dll file or whatever file is more convience.

I'm trying to execute CREATE USER with a given username (via sql parameter)
exec sp_executesql N'CREATE USER @LoginName
FOR LOGIN @LoginName;',
N'@LoginName varchar(5)', @LoginName='myuser'
Heres the code thats generating the above:
Dim myCommand As SqlCommand = New SqlCommand("CREATE USER @LoginName
FOR LOGIN @LoginName;",
ClassDatabaseConnection.CustomInstance)
[code].....
I get and error:Incorrect syntax near '@LoginName'.I think this is due to the parameters being passed as VarChar causing 'MyUser' rather than MyUser Can I not do this with sql parameters?
