I have a comma delimited text file. I need to write this file to xml. I was thinking of first loading a dataset from the text document and then working from there. Is this a good way to go about it?Also how would I load the dataset from a comma delimited text file. The text is enclosed in quotation marks which I want to be removed
View 7 Replieshow to load a XML file Embedded in the resource project?
I've do some google, but did not found anything useful
I've place my XML document in the project resource, and I wish to load it in a DataSet/Datatable.
I have created a local database using the DB wizard in 2008 express.I have created a table called users and I can access the sample data that I have entered into it using a windows form.When I try to add a new record things come unstuck. The record shows in the windws form as being present and the record count increases to indicate this. But when i check the DB itself there is no sign of the record.I am using the tableadapter method as outlined by MSDN. So the question is what am i doing wronghere is the code from the form:
Public Class frmS4

With one xml file it loads the schema and data just fine, but with another xml file it only loads the schema and not the data. There's no error thrown - just no data loaded.
Anybody have any ideas? I've attached the .xml file for your review. I would have attached the .xsd but the system wouldn't allow it.

[Code] .....
so what I want to do should be pretty simple. I've been following the examples found here Using the BackgroundWorker Component - VBForums . I've been successful, but I'm not smart enough to put it in my project.
What I'd like to happen is this
1. I hit a button to load data from a dataset....
2. have a progress bar show until this action is complete.
The main problem is that I can't figure out how to tie the "progress bar" to the action of "pulling the dataset"
I'm sure this is a crazy question for you all, but hey...
Would I put all of the coding in the button_Click sub?
I want to load minimum 150MB of XML into dataset,
simple way of doing that is
XmlDataDocument xmlDatadoc = new XmlDataDocument();
xmlDatadoc.DataSet.ReadXml("C:\books.xml");
But i feel on Lagre size message this code make some performance issue.

I have returned xml data in a variable and need to loop through the returned xml and pull certain data from select nodes.
I was thinking the best way would be to load into a dataset (or datatable) and loop through that.
I also have the xmlschema. What's the best way to code this?
I thought I could do something like so but it gives me the following error: DataTable 'newdt' does not match to any DataTable in source.

I've had a vb.net application for quite a while. Today, when I tried to load a form (one of many in the app) in Design mode, I got the error: "Could not load file or assembly 'Interop.MSMAPI, Version=1.1.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified." This form is the only form using msmapi, and the only one that won't load in Design mode.I can edit the form's code, run the application, and deploy the application. But I cannot access this form in Design mode. It's been a few months months since I've opened this form in Design mode, but it worked last time I tried it.

View 12 RepliesI am looking for some guidance with the most optimal or efficient way to export a dataset to an excel file. I have searched the forums and found a number of methods to do this. However, the code I am currently using is very inefficient as it is itterating through the rows and columns to create the excel file. The app I am working on needs to be able to create 50 or so excel files each with 500+ rows and 40-50 columns. This method seems to inefficient for my use.
I have seen some code out there to use an ODBC call to excel to create the file. I am wondering if someone can verify that this is the most efficient way to meet my goal. It should also be noted that after the export I will want to do some basic formatting of the sheet. Adding bold column headers, autofilters, and autofit all columns.
I've only dealt with firing a single SQL statement at a SQLServer table and returning a single result... easy....
however....
is there a way to fire a dual sql command and load the results into respective tables within a dataset?.. I'm thinking something along these lines (this code of course does not work)
Dim ds As New DataSet
Dim dt1 As DataTable = ds.Tables(0)
Dim dt2 As DataTable = ds.Tables(1)

have a lot of experience with LINQ, but should your verb be attached to the array?
data.Tables("people").LoadDataRow(parsed(int1, 1), True) S/B
data.Tables("people").LoadDataRow(person.parsed(in t1, 1), True)

I'm still in my novice stages of .net development, and I think I may be trying to make something too complicated.In VB.Net 2008, I'm using a SQLDataAdapter to Fill a dataset with records being returned from a Stored Procedure (SQL Server 2005).I'm using that dataset as the datasource for a gridview.
