I am creating XML files and load them back again. I use this following code to write xml to a folder. the code below will put date and time to the file name. and this code works fine.[code]...
Again, I want to load the last xml file back and put in a dataset. I normally write code like [url]...
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

how 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 am not sure why my dataset is not being posted into datagridview
Sub to load the form and datagrid view

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.
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 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)
How do you load a variable directly from a db record entry Thought it would be something like this
Code:
Dim TempUserName as string
Me.TblUsersBindingSource.Movefirst
TempUserName= Me.TblUsersBindingSource.List("UserName").Tostring()
Apparently not....
I dont know how to dynamically populate a dataset based off the tables in an existing database.Once I can get the dataset to populate, I can then move forward with the next step of the project.

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. Up to this point, everything is great and I understand what's happening.I'm getting ready to make my first-ever attempt at updating the data in thegridview and then pushing the updates back to the SQL dB.Here's where I'mgettingconfused...to cut to the chase, what's the simplest way to load the updates back into SQLServer?

In a VS2010 solution I have a license.licx file that contains:

DataDynamics.ActiveReports.Export.Pdf.PdfExport, ActiveReports.PdfExport, Version=6.1.2814.0, Culture=neutral,
[code]....
If I build the solution on a machine that HAS a license for ActiveReport then everything is fine. If I build the solution on a machine that DOESN'T have a license for ActiveReport I get:
Error 1 'Could not load file or assembly 'ActiveReports6,
Version=6.1.2814.0, Culture=neutral, PublicKeyToken=cc4967777c49a3ff'
or one of its dependencies. Operation is not supported. (Exception
from HRESULT: 0x80131515)' LC
On the machine that DOESN'T have a license for ActiveReport if I remove the above lines from the license.licx file then everything builds fine. I always thought that if the license couldn't be found then the unlicensed version will be used but it wouldn't kill the build. How do I get this solution to build on any machine whether it has a license or doesn't?

I want my app to load a .exe file specified by the user, crypt it then save the crypted .exe file on a path also specified by the user. I need some guidance on this. First of all, I am currently using IO.filestream to store the .exe file. When I save the completed file (so far in development, that means a copy of the file as I haven't added encryption yet) the .exe file appear there alright, but without the icon (it has the standard/no icon instead) and it does not work. I tried outputting it to a .txt for examination and it was a bunch of tokens as one would expect. Here is the statements:

I have an issue where I need to load a fixed-length file. Process some of the fields, generate a few others, and finally output a new file. The difficult part is that the file is of part numbers and some of the products are superceded by other products (which can also be superceded). What I need to do is follow the superceded trail to get information I need to replace some of the fields in the row I am looking at. So how can I best handle about 200000 lines from a file and the need to move up and down within the given products? I thought about using a collection to hold the data or a dataset, but I just don't think this is the right way.[code]....
