I am building a website using visual studio and an access database. When more than one user is entering data and they submit the info is going to multiple pages. It should only go to the pages that are designated. this does not happen if it is only one user. Is this my dataSets or am I missing something.

What do you mean by "the data is going to multiple pages"?

The data is going to multiple records in the access database if there are more than one person entering data at the same time.

I was wondering if I could insert a file into resource (.RES) file during runtime instead of inserting a file using resource editor at design time. Could anyone help me with this information ? Thanks in advance.

No, you can't.
Since the resources are compiled into the target .EXE at compile time, any changes you make to the file won't be reflected in the target .EXE until you recompile it.
The resource editor is part of the Visual Studio IDE and is not available to your .EXE at runtime. That is, unless your making a Visual Studio add-in...

I am not sure I am calling this user defined function correctly. I have set the variable ID equal to the value from a drop down list and am trying to pass the variable to the user defined function.
Dim id As String
id = ddlDriver.SelectedValue.ToString
Dim conn As SqlConnection
Dim cmd As SqlCommand
Dim dn As DataSet = New DataSet
Dim da As SqlDataAdapter = New SqlDataAdapter
conn = New SqlConnection(server information)
cmd = conn.CreateCommand()
cmd.CommandText = "dbo.get_tractor'" + id + "'"
da.SelectCommand = cmd
da.Fill(dn, "tractor")
I keep getting an error and have checked the dataset through the quickwatch and it always comes back null.

I just need some help on how to build a file & folder finder (any).
I want to use a textbox, a button and a msgbox to display the findings.
I can find files by using " exists " and hard code path, but I'd like to do it
differently, like more user friendly, like typing the file name (any file) in the textbox and then
clicking the " find " button.
I'd know how to use the system.io namespace for file & folder manipulation, but i do not know how
to combine both.
Like how can you type a file name in a textbox, and get the location of that file?
Is that possible?

I created a dataset in form1. A button on form1 calls form2. How can I get access to the dataset on form1 while in form2? Thanks for any help provided?

Read this[^]. It's alittle bit on the VB6 to .NET upgrade, but it also shows you how to pass data between forms.

I am currently trying to read binary values from the windows registry, with the requirement to compare and set a specific option in my program. I have tried using the following: Imports Microsoft.Win32, but have so far failed to read or write binary to the registry. If any one has code or knows how this is possible, your help would be much appreciated.

Got a sample of the code your using? Also, what's the registry data type you're trying to read and under what key?

k, at the moment i dont have sample code to read and write binary, thats what i need. However this is the key im trying to use
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Video\{3A293CEE-EFF6-475C-9F1F-730951135E97}\0000
This stores entries for the settings for the NVIDI Gfx settings which im making a tweak tool for, and cant read most of the values as they are binary.
Any help would be appreciated. I can get this working in VB6, but however would rather use .NET as I am able to add Navigation bars and office style buttons.

First, yoiu should be opening CurrentControlSet, not ControlSet001.
Dim rk As RegistryKey
rk = Registry.LocalMachine.OpenSubKey("SYSTEM\CurrentControlSet\Control\Video\{yada yada yada}\000")
Dim data as Byte() = rk.GetValue("ValueName")
Will return whatever the data for ValueName is in the registry. If you have to return the default value (unnamed) for a key, just use:
Dim data as Byte() = rk.GetValue("")
I think you can figure out how to write the data back.

Thanks for the reply Dave Kreskowiak, however, this does not work.
What I need to do is read a value from the registry, which may be:
01 00 00 10, then I need that to go to a variable, which I then need to check and change a picturebox.image and listbox.selectedindex, depending on what the value is. Also need to write a specific binary value back to the registry, if the user changes the setting.
The above method just won't work and I'm unsure why.

I have no idea what your doing wrong because "just doesn't work" doesn't explain what's going on. Does it return Nothing when you call OpenSubKey? If so, then you have the registry path wrong.
This works perfectly on mine:
Dim rk As RegistryKey
rk = Registry.LocalMachine.OpenSubKey("SYSTEM\CurrentControlSet\Control\Video\{3BAC59C8-BD30-404A-9093-F454D23FF17F}\0000")
Dim data As Byte() = rk.GetValue("_Wow.exe:D3DOGL_67207556")
It returns the 4 byte value array of 0x01 0x00 0x00 0x08.
