Just curious if you were still waiting for a response and still drowning?
snicker, snicker.
Any suggestions, ideas, or 'constructive criticism' are always welcome.

Your question is so general that it borders on unanswerable. Noone can give you a clear answer because your asking about how you should design your application, but provided no details about it that would drive an appropriate answer.
Also, the various parts of your question have nothing to do with each other! "Dynmaic relations" does imply any differences between how your data model would react to a users privilege level. On top of that, I fail to see how "Socket Programming" would affect how your data model is designed.

Is this homework, or has some country actually outsourced such software to people who don't know what they are doing ? Is there any chance that your bugs will kill people when two trains collide ?

I have been working on a database program with a Access database. I have on one form a datagrid and it has "Employee Table" table on it. Now what I want to happen is if you click on a row and click "Open" button (btnOpen" it fills the information to another form with text boxes like "TxtAdd1" (Address) and so on.
Also, I have a save button on the form with the text boxes (Save Form) and what I want is to be able to save the information in the text boxes as a new employee in Employee Table, but if the employee ID is same as already in the database table, it will say message "This employee ID already exists, would you like to overwrite current employees information?" (Yes or no)
Any help would be appreciated. I am trying to make this so I don't have to use databound items on text boxesThanks in advance.
In the end we're all just the same

You need to write code in the button click events of both the buttons. In case of open, get the selected row and fill its data in the textboxes. In case of save button, use classes in OleDB namespace to save data.

Assuming this will be the primary key, it should be auto-incremental or should be generated through code. Why are you letting user create the IDs?

I fixed that, just realised the ID should be an autonumber. Anyway is there a way of adding the information on all the textboxes to the database table as a new user... the txtAdd1 text will be stored in Address 1 cell and so on.
In the end we're all just the same

Create a stored procedure in your database and send the textbox values as parameters or build a query in your code and perform insert/update using Command object.

u should use command builder to save or update which will generate command dynamically insert for new and updated for existance.

Obviously you need to step through and work out why m is not -1 when you want it to be.

I think you actually want to do a replace rather than remove

You can't, unless you do an indeterminate one. Of course, it also needs to run in another thread.

I would like to know how to write out excel 2003 excel worksheets to separate files. Basically I need to write out each excel 2003 file generated by a vb.net 2005 desktop application to separate workbooks. Each separate worksheet is going to be email and encrypted for each customer.
Thus I would appreciate any suggestions that you have how to accomplish this task.
Thanks!

I'm assuming you already have Excel interop code written that creates the worksheet.
All you do is create a new Workbook, add a new Worksheet to it, populate it, and save. Rinse and Repeat.
Google results for "vb.net create new workbook"[^].

Dave Kreskowiak:
Thank you for your immediate response. However my question is can I reuse the excel object embedded in the vb.net 2005 desktop application? I need to put the output from sql server 2005 on separate spreadsheets for different customers. To accomplish this tak, it looks like I need to close and reopen the excel object each time I need to write to a new excel worksheet. Thus is there a way that I could reuse the object?
Thanks!

Yes.

Not true. You just close the existing workbook after you save it and create a new workbook, then add a new worksheet to it.
jazzgirl wrote: is there a way that I could reuse the object?
The simplest route, though no the most proper, would be to just create a class-level variable to hold the Excel app object, then you can use it through out the form class.

Hi I programmed Xcell Object in VB6 , and Here is My Idea ,How it works , it may not be
much different from VB-Net Code :
To Read from a specific cell on the Sheet --> to a variable use following Formats :
-----------------------------------------------------------------------------------
NUM = Val(Form1.Spreadsheet1.Cells(9, 5))
BRN = Val(Form1.Spreadsheet1.Cells(10, 5))
And To Write a value from a Variable to a Spesific Cell on a sheet Use Format below :
----------------------------------------------------------------------------------------
MM = 4 :' Say or any other value.
Form1.Spreadsheet1.Cells(MM + 3, 1) = MM
-----------------------------------------------------------------------------------------
If You are in Sheet1 and you want to send Output to sheet3 , this is Simple, Just Change
the sheet # and provide the Cell adress exactly as an example see :
JK ... has some value send it to sheet3 :
Form1.Spreadsheet3.Cells(7, 5) = JK
I hope I helped .

As far as I can see, i needs to equal 1 for this to work ? Have you stepped through the code to see what is blowing up ? Have you googled the HRESULT ? Is that all the error message you get ?
I googled the HRESULT and this was the first hit:
