Execute SQL Command For A Dataadapter?
May 14, 2012
Is there a way to execute SQL command for a Dataadapter rather than regular approach.
I i have parameters to pass to the SQLCommand. In he below model DAtaadapter at declaration itself we need to pass the SQL as string, and Conn. But i wan to send SQL Command to the adapter to execute instead command as string
Previously i have used to fill dataadapter as below
dbSource = "Database= DataBase;"
conn.ConnectionString = dbProvider & dbPassword & dbSource
If conn.State = ConnectionState.Open Then

I'm having problems loading a csv file using dataadapter with ODBC command. Here's what I have:
Dim conn As OdbcConnection
Dim dt As New DataTable
Dim da As OdbcDataAdapter
Dim connectionString As String
Dim iFileRecords As Int32
[Code] .....
I get the following error:
"ERROR [42000] [Microsoft][ODBC Text Driver] Syntax error (missing operator) in query expression 'CAST([Preferred Phone Number] AS varchar(30))'."
The reason I was trying the CAST([Preferred Phone Number] AS varchar(30)) AS PNo was:
If all of the Phone Numbers are added with spaces e.g. 086 1234567, it works using SELECT [First Name], Surname, [Preferred Phone Number] AS PNo FROM [" & Me.ImpFileName & "]"
but if they are without i.e. 0861234567, it doesn't work hence trying to use CAST.
My guesses are to either force the import process to treat the [Preferred Phone Number] as text or get the CAST expresion to work but I've failed on both counts! I've tried the command in SQL database (albeit using SQL rather than ODBC connection) selecting from a table using CAST and it works fine.

Its something in the syntax for the command.
They provide this example in VB:
Dim MtbApp As New mtb.Application
Dim MtbProj As mtb.Project
Dim MtbCom As mtb.Command
[Code]....
what I'm expecting should happen is Minitab should open, and the command should execute. However, whats happening is that two instances of Minitab are being opened and neither are showing user interface, I have to find them in processes.

I have an executable that I normally execute from cmd window. Now I want to write a vb program that does it, captures the output that the program would normally show on commandwindow and does some further stuff with it. Shell would be the starting point, I guess.

I am trying to execute a shell command with vb.net that includes variable from the vb.net code.I have experience with batch, and Unix scripting. I had to modify the contents of the code as it is confidential to me at the moment.Example of my problem:
Dim Variable1 As String = "Location_to_.exe"
Dim Location As String = "UNC_Path_Goes_Here"
Dim Options As String = "/Options go here"
Shell("cmd.exe", /C Variable1, Location, Options) This is something that must be run from CMD.exe and I am trying to do it this way to make it as dynamic as possible.

Lets just say we have this as Command1 Dim Command1 = "whoami.exe >> C:Hello.Txt" The program will read a list of users from a text file and then perform the action on each of them. If the user does not exist, or they are part of a password protected computer, I would like to see that in my printout. I have this but am Unsure how to write the If Then Statement (If that is the ebst route to take)

I need to convert a .tex file to a .dvi file (latex file), which I can do simply using a command in the cmd window: "latex C: est.tex" for example, would create the "test.dvi" file from the "test.tex" file.
I know how to start the cmd window (Process.Start("cmd.exe")), yet how to get VB to actually 'type' a message and execute it...

I've done a little bit of LINQ but I almost exclusively return some elements from a collection based on some criteria. Now I'm trying to do something similar; let's say I have 50 winForm Controls in a collection - I want to set the .Visible property = True based on the controls name.
How would I do that? Below is my failed attempt.
myControls.AsEnumerable.Select( Function (myControl as Control) ( myControl.Visible = (myControl.Name <> "Hidden")) )
It compiles and even executes but does nothing.

I am using ASP.NET
If I want to execute my Insert command from my SqlDataSource in my code behind I would do this.
SqlDataSource1.Insert()
But how would I be able to do this in JavaScript?
<script type='text/javascript' language="javascript">
function valSubmit() {
//Need to call the Insert Command here!
[Code].....
Where in my code behind can I place the Insert() command to make sure only after my valSubmit() function in JavaScript have executed it will then execute the Insert Command?

I have been searching for a good code example that will place a small server program on my server and then allow me to use a client on my pc that will tell the server program to run a batch file on the server.
I thought this would be simple... I am finding it not that easy.
We have a server that users need to execute a command on however we do not want them to have login rights to the server so this will allow them to execute the batch file without having to log in.

I'm working on creating a windows service that will send emails to a customer when they are within a month of having their submission expire. I'm using vb.net in Visual Studios 2008
Because it's a windows service it's very difficult to debug. Trying to narrow down my error I created a "sendDebugEmail" method that sends me an email if it gets to a certain line. The emails never make it past "dr = cmd.ExecuteReader()"
I'm wondering what I am doing wrong. My SQL statement should work fine. I've tested it in my SQL server database.
I've created a dummy_database that I just made in sql server as well. I added an INSERT sql statement for the dummy table i have in there just to see if i could actually access a database. All the table takes in is the line number and time it was sent. When I run my windows service that database updates just fine.[code]...
