Stored VB.Net procedures consisting of many subroutines and a few functions
working with one SQL Server 2005 datbase. The problem is as follows:
Sub A receives a table name, a query name, and a directory path name.Using
Dim RecordTypeSet As SqlDataReader
Dim RecordTypeConnection As New SqlConnection
Dim RecordTypeCommand As New SqlCommand I open a reader
from the sql located at directory path name & query name
and While RecordTypeSet.Read()
I create a record which I want to store in the table name provided.
In order to do this I call a SUB B with the record and the Table name.
Sub B builds an insert query and using
Dim SummaryConnection As SqlConnection
Dim SummaryCommand As SqlCommand
Dim SummaryReader As SqlDataReader
SummaryConnection = New SqlConnection("context connection = true")
SummaryConnection.Open()
SummaryCommand = New SqlCommand(sql, SummaryConnection)
SummaryReader = SummaryCommand.ExecuteReader()
errors out on SummaryConnection.Open()
end sub B
wend

What's the error?? Why does everyone leave out the error description when they post "I have a problem!"?
Does the method that this error occurs in have the SqlProcedure attribute on it?

With SqlProcedure Attribute I get a deployment error on SUB_A
because it has a Byref Class instantiation to return data to the caller

This is utterly useless. Copy and Paste the code in a post. The "Sub_A" crap leaves out details that are required to see what's going on.
You also didn't answer my question. Does the "sub" have an SqlProcedure attribute? Copying and pasting the code probably would have showed that! And, the EXACT error message would help more, not your interpretation of it.
The "context connection = true" only works inside an SqlProcedure attributed function. Without it, you may as well use a seperate connection using a normal connection string.

I did not originally have the sql server attribute declared
Your first question prompted me to insert that and try again.
When I did, I got a deployment error on the byref use. I am currently
trying to find another attribute to solve that problem. Here is the code

It "aborted" with what error message?!! Do you actually want help? This is the third time you've been asked for the error message. Why are you being so evasive?
I'd love to help, but I'm not going to read through the code looking for the cause of an error until I know what error I'm supposed to be looking for.

Running the code last provided
"Error The context connection is already in use. occurred in Module: sbUpdateSummaryProfitnLossTableRecord"
"Error 5 occurred in Module: sbUpdateSummaryProfitnLossTableRecord" was obtained from my error handling
I captured the following output.
A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll
A first chance exception of type 'System.IO.FileNotFoundException' occurred in Clrtest
I think I am trying to use MARS in this environment. Is this even possible?

Hello,
[VS 2005]
I have created a user control that has a tab control, text boxes, combo boxes. I have a typed dataset with some datatables and tableAdapters for doing the inserts and the delete, and updates.
I build the control and when I want to use this control in another project.
1) open a new windows form project
2) Create a new tab on the tool box
3) Choose items
4) Browse to the dll in the release folder.
My question when I add the dll it also adds the typed dataset, table adapters. I have done something wrong as I think it should be the control itself and not the table adapters and the dataset. As when I click ok with the above selected it add them to my toolbox.
Can anyone explain about this, and if I have done done something wrong.
Many thanks for your help,
Steve

How to get or to collect all objects or controls in a form using vb.net? For example of controls are Textbox, Combobox and check box.
|
|
|
|
|
Every form has a Controls collection. This is where you'll find all the controls on the form. There's a little bit of a "gotcha" though. Controls can have Control collections of their own, so you can end up having controls inside other controls, like RadioButtons in a GroupBox or Panel.
You can enumerate the controls like this:
For Each c As Control In Me.Controls
If TypeOf c Is Panel Then
Dim tb As Panel = DirectCast(c, Panel)
' do whatever you want with the Panel you found
End If
Next

The code is nice and all, but where's he going to get the ChilkatZip2 class library from?

You can use the #ZipLib to do this. Find it here[^].

devkranth wrote: i need to blink the label in vb.net
You'll have to create a custom label control for this, easily done by inheriting from the existing Label class. You'll need to add a Timer to your control, and a couple of properties and methods so you can set the blink rate and start and stop the blinking. Then it's just a matter of making the foreground color match the background color and changing it back to what it's supposed to be on every timer tick.

Use a timer to set the Visible property of the label to either true or false.

I am using the following code to list the accounts of my operating system.
Currently i have just two accounts namely
1.Administator
2.Guest
But it shows 6 accounts.
can i filter the query to make it to show the actual accounts.
Dim oQuery As New Management.ObjectQuery("select * from <br />
Win32_Account WHERE SIDType = 1")<br />
Dim osearch As New ManagementObjectSearcher(oQuery)<br />
Dim ocollection As ManagementObjectCollection = osearch.Get<br />
Dim oresult As ManagementObject<br />
For Each oresult In ocollection<br />
TextBox1.Text = oresult("Name").ToString & " "<br />
Next
Thank You
Pankaj

I think it is showing the real accounts, with the `hidden` accounts, such as the help and support account, if you have VMWare installed, __vmware_user__ and other things.
You could try:
For Each oresult In ocollection
Dim oname As String = oresult("Name").ToString
If Not oname.StartsWith("SUPPORT") Then
If oname <> "__vmware_user__" Then
If oname <> "ASPNET" Then
If oname <> "HelpAssistant" Then
textBox1.Text = oname & " "
End If
End If
End If
End If
I don't know if this'll work very well.

hey there,
i am working in an organisation that uses foxPro for its DB needs. We are trying to convert it to SQL. how do i do that? also is there a possibility to develop a VB (not .Net) appln that uses foxpro as its back end?

No idea. I've never used FoxPro and, most likely, never will. I would assume that it would take a re-write of the entire database.
preci wrote: also is there a possibility to develop a VB (not .Net) appln that uses foxpro as its back end?
Sure. You'd use the OleDb database objects, just like you would with an Access database. YOu can find the correct connection strings here[^] at ConnectionStrings.com.
