I am using .net 2.0 and I am getting an exception of system is out of memory. My existing function takes datatable as input parameter which contains little bit large data (eg. more than 35000 rows) and in that function I am appending some xml node data and atlast I am returning the stringbuilder as a object.

I have a SSIS package that runs every 5min.My package has an error routine in the onError event handler but I don't want it to get in there.So in fact, the package should just exit / close / kill itself without any warning or error.Preferably this should be initiated by the script task (vb.net 2008)

How can I kill the excel.exe process in SSIS during the data flow task when it fails? There could be multiple instances of Excel.exe running from other packages that are perfectly valid so I don't want to loop through all instances killing them.My problem is that during the data flow task the process will sometimes fail due to a sheet that is named incorrectly or missing columns. This keeps an instance of excel.exe running which is now an orphan task eating up resources so it needs to be killed.At the same time there are other SSIS packages running that are accessing their own excel.exe process and aren't having any issues. So how can I kill the orphan excel.exe process without impacting the other excel.exe process?

Here is the code I am working with, everything works fine up until last line then i get evaluate exception unhandled "Cannot perform '=' operation on System.Int32 and System.String." My eyes are going blind trying to figure out whats wrong, if I understand correctly it cant count system string and REO is a string value.
The thing i have done this before ,count that is. I know you cant average strings and some other function but i have been able to count.

I am facing an amazing problem in my application. On my Developement server when I am running my application, then there is one function where I am trying to put whole stringbuilder contents in a string object. This Function is used for paging the reports.For that I am using a method of Stringbuilder.tostring() and when I chek the value of this statement (stringbuilder.tostring()) it shows no such interface is supported, which later on throws exception of system is out of memory. Here i am using .net 2.0 framework and sql server 2005 database.But when I run the application on stagging server then there is no such exception thrown.[code]

Whenever I try to modify "any" Dataset using the designer in a specfic projet, I get the error mentioned in the title. The designer works OK in other projects.Steps:
1. Open the the dataset.xsd from the solution explorer.
2. Right click in thedesigner and add Tableadapter.
3. Click the Next button twice to get to the "Enter SQL Statement" and click "Query Builder" button.
First Error Message: "The Query Builder Faied..." "The Parameter is Incorrect" Click OK and click the "Query Builder" button again...2nd Error Message: "The Query Builder Failed..." "Attempted To Read Or Write Protected Memory.This is often an indication that other memory is corrupt."
This one particular dataset has been editied a number of times. Furthermore, in this project, I now get this error in all three (3) datasets I have in the project. Is there a way to start a new prject, import the form andf class objects and create an entirely new set of datasets? I've tried this with no success.

When testing the followng code from Mastering VB2010, I get an Unable to cast object of type 'System.String' to type 'System.IFormatProvider' exception.In the Button1_Click event code Dim strmOut As New System.IO.StringWriter(SaveFileDialog1.FileName)the 'SaveFileDialog1. FileName' is underlined with a green squiggle and displays the following tool tip:Runtime errors might occur when converting 'String' to'System. Iformat Provider'.This is apparrently the problem but what does it mean and how do I fix it to get the code to work?

I have created a query method for my tableAdapter in the dataset designer. I typed the command text manually, but tested it in the query builder after I got a Constraint Exception when debugging. When running in the query builder via 'Execute Query' I get exactly the results I expect. When running the application I get this exception: "Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints." I tried temporarily setting my dataset's EnforceConstraints property to FALSE but still get the same exception. I can't understand why the Query Builder would return the correct datatable but running the app would not. Is this a bug?

My DBA has several SSIS packages that he would like the functionality of providing the end user with a way to input values for variables in the package. What would be the best solution for creating an application that would take the user input and pass the data through to the SSIS package variables?
I can get this work locally using this code
Dim packageName As String
Dim myPackage As Package
Dim integrationServices As New Application
[code]....
Problem is this requires that the user have SSIS installed locally.

I'm looking for a form builder / questionnaire system that will let me build a questionnaire and collect data for insurance applications. I don't want to have to build this whole thing by hand. I've looked at a few options out there and the closest is Formulator.Net [URL]. What Formulator is lacking, though, is a way for me to pass parameters to be stored in the results in the database so I can identify who filled out the form.

I found this piece of code which works fine for my input (a string of CSV). The package runs fine, but instead of getting 5 columns of output, I only get 2 columns. I added additional columns in the Script Component and also changed their data types to the suitable ones. The input is 643492,PV STRIP 1X1 UTILITY UP,,67.5,393446. Out of this entire string, I only get 643492 in one column and PV STRIP 1X1 UTILITY UP in another. Rest of the string comes out blank no idea why. I dont know anything about .net and I am new to SQL Server as well.

I've created a log in system using a database and query builder to return the correct values, however, once the users signed in I need to bring up the rest of their data from the same table in the database. How'd be the best way of going about this? I'm not sure whether the log in should be changed to use the primary key as well.

I have a large project where we have 2-3 dll projects that are converted from VB6 to VB.NET. We have fixed all the issues that caused compilation errors, and most of obvious issues in running, so now we have basically a program up and running. The exe is created from scratch in VB.NET, using a lot of functionality from the converted dll's (including GUI forms). What I wonder is when I run the program in debug mode, I get a bunch of warnings in the "Immediate Window" saying:
A first chance exception of type 'System.Exception' occurred in Microsoft.VisualBasic.dll
...and some of other type (but most of them in Microsoft.VisualBasic.dll).I was wondering if this is common in projects converted from VB6, or if it is caused by bad design in our code...

I am pretty new to Visual Basic and am only using it to create a very simple programme. It is essentially an interactive encyclopedia where the user can type in a subject into a text box and get a form with information on it to pop up. I am not using any data sets etc. While the forms are all very simple and the code very limited there are dozens of forms involved, this was working fine until recently when I started to run into OutOfMemoryExceptionThrown every time I try to build my program and debug it. This exception started appearing sporadically with the programme sometimes compliling fine and other times refusing to but now it is every time. I have never written code to do this before so how do I got about freeing up memory? I read in a similar post that it may be connected to allocating memory and then not freeing it up again, or perhaps having too many event handlers in my program without ending them, however I am lost and don't know how to fix these problems.

I created a simple VB application in Visual Studio 2010.My computer, which I am using to create the program, is Windows 7 Pro, and SQL Server 2008 is running on a Windows Server 2008 Enterprise, which I have full access to.
I want to click a button and have an SSIS package execute.I looked around on the Internet and found examples, but they do not seem to work for me.I try to add a reference, Microsoft.SqlServer.ManagedDTS.dll, as a few sites advise, but it is not listed when I go to PROJECT>ADD REFERENCE.
I also type:
Imports Microsoft.SqlServer.Dts.Runtime but all I get is a squiggly green line, which when hovered over states "Namespace or type specified in the Imports 'Microsoft.SqlServer .Dts.Runtime' doesn't contain any public member or cannot be found." Below is some code I copied from one of the websites and pasted in my button click event (the path is correct), but a get blue squiggly lines under "Package" and "DTSExecResult":
Dim pkgLocation
As String
Dim pkg As
New Package[code]....
What can I do to make the SSIS package run when I click the button on the Windows application a created?
