Hello,
Is it possible to call a SqlDataSource from a DLL within a method like you can from the CodeFile? I'm getting this error: The Name SqlDataSource1 does not exist in the current context when trying to call it from within a method defined in a DLL. Thanks!
<!-- Trying
to create a GridView Survey form:
Hi [User]
Do you have these assets?
[Gridview]
Tag Number Response
123
[Yes ] [No] [Comments textbox]
234
[Yes ] [No] [Comments textbox]
Goal: The desire
is for the user to click Yes or No and have the database updated with the
user's name, date, response and any comments.
So far, I have
created SqlDataSource with Select and Update commands, created the gridview and
response buttons, setup the RowCommand and On_Updating Functions.
Problems:1) If I call the update() function for SqlDataSource1 and misuse the Defaultvalue parameters to run the sql, no update is posted to the database.
2) If I use the On_Update function to set the parameter values, I get "Data type mismatch in criteria expression." (Additionally, the On_Update function runs twice which I don't understand)Can anyone tell
me what/why? (and how to fix it?)Sorry for the deluge, but here is the code:

Ive run into a situation where some code im using will not function the same when between these two cases. So, this has me wondering what is going on behind the scenes. What is the sequence of events that are occurring that would possibly be messing things up.Here is the sample codeIts a gridview that is using a sqldatasource control. The code works fine, but if you want to bind the grid to a dataset and call databind yourself, things dont work as expected and the other features that the code performs just isnt happening, at least not for me.
View 1 Replies View RelatedWhat is the C# code I use to do this?
I'm guessing it should be fairly simple, as there is only one row selected. I just need to pull out a specific field from that row and then insert that value into a different SqlDataSource.
i am using visual web developer 2005 with SQL Express 2005 with VB as the code behindi have one database and three tables in itfor manipulating each table i am using separate SqlDataSource() is it sufficient to use one SqlDataSource() for manipulating all the three tables ? i am manipulating all the tables in the same page only please help me
View 1 Replies View RelatedHi all, i have a DTS package that i call from a C# app, i had it working great until i decided to use an activeX script to do the data transformations instead of the row copy. I need to use ActiveX to add a standard name to the last column in the destination table. the problem is the task is executing without errors (from c#) but nothing is happening, its failing silently. If i modify the Data Transformation back to a standard column mapping (with separate DTSTransformations for each column) it works fine, but as soon as i use activeX to handle the transformations it doesn't work. Can anyone tell me what i may be doing wrong. heres the calling code from C# if(f.Name.Substring(13,7).ToLower() == "product")
{
try
{
activity.Log("Starting Product DTS Package...");
DTS.Package2Class package = new DTS.Package2Class();
object pVarPersistStgOfHost = null;
package.LoadFromSQLServer(
"192.168.8.8",
"username",
"thepassword",
Microsoft.SqlServer.DTSPkg80.DTSSQLServerStorageFlags.DTSSQLStgFlag_Default,
null,
null,
null,
(string)ConfigurationSettings.AppSettings["productDTSPackage"],
ref pVarPersistStgOfHost);
package.GlobalVariables.Item(1).Value = f.FullName.ToString();
package.Execute();
package.UnInitialize();
//force release of COM object
System.Runtime.InteropServices.Marshal.ReleaseComObject(package);
package = null;
}
catch(Exception e)
{
activity.Log(string.Format("Failureprocessing {0}",WorkingPath + f.Name) +" - "+ e.Message);
} and the activex i tried to use for the transformations is: '**********************************************************************' Visual Basic Transformation Script'************************************************************************' Copy each source column to the destination columnFunction Main() DTSDestination("Yesmail Id") = DTSSource("product series") DTSDestination("Customer CKM CustId") = DTSSource("product family") DTSDestination("Product SKU") = DTSSource("transaction date") DTSDestination("product model name") = DTSSource("serial number") DTSDestination("serial number") = DTSSource("product model name") DTSDestination("transaction date") = DTSSource("Product SKU") DTSDestination("product family") = DTSSource("Customer CKM CustId") DTSDestination("product series") = DTSSource("Yesmail Id") DTSDestination("fileName") = DTSGlobalVariables("sourceFile").Value <-- this is why im using the activex for this field to get a Global Variable. Main = DTSTransformStat_OKEnd Functionthe weird thing is the PACKAGE runs fine from ENTERPRISE MANAGER with this activex, it just doesn't do it from my Calling app, perhaps i have missed something i need to change in the package constructor? BTW: i do have my assembly signed in C# for the COM wrapper.thanks in advance, mcm
Hello,
I have done extensive work with Classic ASP for 9 years now. Working with Stored Proceedures etc
However now am working in c# am adviced by a friend that its best to use the
1. The "Object data source" to call SP
2. Are there any documentations pointers on best practices, how its done ?
I want to use the "on click event" in my class file.
thanks

I'm developing a new Stored Proc that will be taking information in to enter customer and order info. Looking at the current Stored Proc its using alot of If statements and I'm thinking of breaking the sp up into different Stored Procs and calling them all from One main stored proc. I know how to do this but I was wondering how it would effect performance. So should I simply keep all the stuff in one proc or module it out into multiple ones to make it easier to follow and read?
Thanks

Hi,
Can I call SP in the Trigger? Googled for this but din gt any satisfactory answer.
Thnkx,
Rahul Jha
I'm working in SQL Server 2005. I have an existing SP that does exactly what I need (it's the aspnet_UsersInRoles_IsUserInRole SP). I want to reuse this SP and use it's return value as a field in the SP I'm writing. How do I go about doing this? I could take the logic out of the called SP and wrap it in a function; but, I would really like to reuse the SP aspnet_UsersInRoles_IsUserInRole. Thanks in advance for any assistance.

i'm trying to call a dts package from vb.net.
i got 2 examples which both don't work.
first one gives me a [DBNETLIB][ConnectionOpen(Connect()).]SQL Server does not exist or access denied error.
source code:Dim serverName As String = "SERVERNAME"Dim oPackage As New DTS.Package()Dim oStep As DTS.StepDim pVarPersistStgOfHost As Object = Nothing
oPackage.LoadFromSQLServer(serverName, "USERID", "PASSWORD", DTSSQLServerStorageFlags.DTSSQLStgFlag_Default, _ "DTSPASSWORD", Nothing, Nothing, "DTSPACKAGENAME", pVarPersistStgOfHost)
For Each oStep In oPackage.Steps oStep.ExecuteInMainThread = TrueNext
oPackage.Execute()
Dim err As LongDim source, description, message As StringFor Each oStep In oPackage.StepsIf oStep.ExecutionResult = DTSStepExecResult.DTSStepExecResult_Failure Then oStep.GetExecutionErrorInfo(err, source, description) message = String.Format("ErrorCode: {0}, Source: {1}, Description: {2}", err.ToString(), source, description)Else message = "Success"End IfNext
oPackage.UnInitialize()oPackage = Nothing
second example tries to create a dts package dynamically. this time i get the error that the CustomTask can not be casted, somehting about the QueryInterface.

In my shared hosting environment where I am making large volumes of database calls, I am very anxious to preserve my heavily throttled threads-I presume when I make a database call, that it is going to a separate server and any threads that server may be using are in addition to my " hosting plan ".
My question (s) is, is it therefore a no-brainer to always make calls to:Dim oResult As IAsyncResult = iDBCmd.BeginExecuteReader()arWaitHandles(0) = oResult.AsyncWaitHandleiIndex = WaitHandle.WaitAny(arWaitHandles, 60000, False)
i.e. run all calls to the database asynchronously?
Is it really releasing a thread back to my asp.net App while it is waiting? (I.e. Is it worth doing)
I'm new to using DTS packages and I'm running into a problem. Hopefully someone can help me out. I have an ASP.NET page that needs to call a DTS package. Everything seems to be working right up until I call opkg.Execute. The package seems to run but nothing happens. After further investigation I have found what looks like a permissions issue. this is the message I'm getting"
Error Number:
-2147467259 {Integer}
Error Description:
"The Microsoft Jet database engine cannot open the file ''. It is already opened exclusively by another user, or you need permission to view its data." {String}
This is obviously a permissions issue. I'm just not sure who the DTS package is running as and where to set the permissions.
Any ideas????
Thanks
How to do this?thanks :-)

SQL Server Load Balancing -- Any ideas?
There is no inherent mechanism available in SQL Server (replication, log shipping, or clustering) which allows you to load balance you database server.
Clustering is only useful for a failover situation and does not allow active/active balancing.
Is is possible to use merge replication between two identical OLTP servers
and manage transactions via MSMQ? Will this mechanism allow for a load balanced OLTP server?
Will this work? If not, why not?
What will work? Will federated servers work for an entire database??
I need a simple example of calling a dll or exe with params
from a stored procedure.

hai guys
how should we have to cal the store procedure inside the same store procedure.
for Example
Create procedure A
as
Begin
Select * from mytable
execute A
end.
is this the correct one

Dear Everybody,
Hi again!
Supposing I have an SQL Server Function named Fxn1 which returns a VARCHAR(6) value. I want to use this returned value in another function named Fxn2 but Fxn2 accepts a parameter of type INT. Fxn2 itself returns an INT value. This has to be achieved in a single line.
The following line of code will not work in SQL Server. How should I achieve this?
declare @Res INT
EXEC @Res = Fxn2 (CONVERT( INT, Fxn1 ))
Thanx in advance!
I have a rather complex function (part of a production planning engine) that is written in VBA, and is part of my front end app. I'd like to be able to somehow call this function from either a sproc or DTS package in SQL. Is this possible, or am I going to have to convert the function to a SQL sproc (ugh)?
