I have a database I am creating with about 50 users over a network. There are about 6 groups of users and these users are spread across 10 branches. I want to block/allow users from particular forms and views. For example I want branch users forms to be filtered by their branch number but depending on the group they are in they can only see some forms. i.e. 50 users, 10 branches, each branch has about 5 ppl of where 1 is in group A and 4 are in group B. I want all users that belong to branch 1 to see the information they enter, but Group B enter data but cannot approved or delete, and group A can enter, approve and delete. So then. On my login form I have the user type his/her username but the i want LEAVE function to update 2 textbox where I have named GroupName and BranchNo. Basically to run a query and look for the username and return in one textbox that user's groupname and the other textbox the user's branch no. This information will be used to filter forms and block the user from certain controls. This is the code I have so far but still can't figure how to display the results.

Need advice on what is the best approach to get the auto incremented id to be the same on multiple forms.
Basically I am using VB .Net with SQL Server as the backend. I wrote a few stored procedures to insert data and then I am calling the stored procedures on the front end. I have 3 forms and once the first form is submitted it generates an autoID and then takes the user to 2nd form.
In the second form I have a separate insert stored procedure is there a way to grab the id that the first form generated and for it to be consistent. Or should I store it in a variable after they submit the form and then call it in the second form.
I have a simple application for taking Customer orders and their Products. I am using Visual Studio 2008 Express Edition and MS Access 2007.My application uses multiple forms. One of the forms is an Add form from where a New Customer along with his/her details like address, phone, city, state etc can be added. Another form is for the Product Details to be added.I want to know how to retrieve a CustomerID from an MS Access 2007 database for either the newly added Customer or an existing one and insert multiple rows or records for the same CustomerID, as a Customer can order multiple products. I am using the following code for the Add button:

Im writing a program and its pulling data from a .MDB to put in a .DAT file.
Here is my while loop:
vb
database_connection()
sql = "SELECT * FROM tlalist"
[Code].....
In my database there are currently 6 rows. and only 1 row has the TLA_DAY column equal to 1, but for some reason when I look at the .DAT file it creates it outputs the result twice rather than only once.
Once JTLA_count increments it becomes "2", but the while loop still outputs as if its still equal to "1". Ive used breakpoints and the counter is incrementing fine.

View 2 RepliesI'm creating a form in ASP.Net to replicate a paper form (I have no say in the design, I'm tasked with merely recreating it digitally). This form has many questions along the lines of "Answer yes or no. If yes, specify how much". I'm currently handling it by listing the question, and then having two radiobuttons in a group, one saying "yes" and one "no". To make this a little prettier, I've been using Ajax updatepanels that will only display a textbox to hold this yes value if the user selects Yes.Now I've been able to do this successfully, but each question is its own radiobutton group and has its own panel to update visibility, which means that the way I'm currently doing it there is a lot of redundant code like
[code]...
And so on for every question that has a yes/no option like that. I have no doubt there is a better way to do this. I was wondering if there is a way I could pass the panel associated with the radiobutton group so I could use a single method in the code that would fire for all radiobutton postbacks, something like (not real code)
[code]...
Or is there a better way to handle questions like this? I'm open to a different approach if it would cut down on the amount of redundant code that I'm typing now. I'm using VB, but I know C# so if someone is fluent in that with an answer I'd have no problem interpreting it.

View 13 RepliesI have a problem in timers, I want to display 2 forms each one after 3 and 5, how to do that? I mean when the first form appears, after 3 seconds another one will appear, then after 5 seconds the second will appear. I have a code where someone gave me here but its for message box only, thus I modify it to put a form still does not work. Here the code I put in the timer below:
Private Sub frmblabla_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
tmrnote.Start()
Private Sub tmrnote_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tmrnote.Tick[code]....
I still have problem when the message box stops, it displays all the forms together. All I want is when the message box stops, then it display the first form then stop to display the second then stop to display the last. The first form must stay for 3 seconds on the screen, then after 3 seconds the second appears then after 5 seconds the last appears.
Is it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?

Inside a form, I would like to display a pdf file which is already available in my resources (template file "untitled"). In this pdf file, I have some fields which get their values from some texboxes in another form. My aim is, when the user triggers the button to call this form, it should insert the values inside the pdf file and display the output pdf inside the form.I have written the code to an extend but could not finish it myself after my many trials... Now here are the two things I cannot manage:I can use a directory to read the template pdf "untitled1.pdf". But my aim is to use the file inside my resources. can save the output file in a directory but this is not I want to do. I want to display the output pdf.
