VS 2008 Cannot Import Data Into Dataset Using ReadXML
Jul 18, 2011
I have a Dataset Lets call it Dataset1. I have 1 table in this dataset created in designer called settings. I want to be able to declare the intial dataset in one form as a global variable and make a copy of it in another form. However I don't want to fill it until after I have made the copy except that it is not working.[code]The problem is the Dt returns the same amount of columns and the exact column names that I have in the settings datatable. When I do Dt.ReadXml("Myxmlfile") I don't get any rows populated yet the columns are in the xml file and in the dt copy of the datable.

Following is the code which gets xml data from web service and then dataset reads using ReadXml method. This Xml has ID and MyDate tags for each table row (so table(0) will have ID and MyDate columns) and this Xml data does not have schema associated with it. When page is loaded first time, it sorts by ID in asc order. It was working until ID was 999. When next ID came as 1000, even in ID asc, 1000 is showing before 999 in datagrid.
I wanted to confirm that when dataset is loaded using ReadXml, all the columns in its table are treated as string even they are numbers or dates and that's why in ID asc order 1000 is coming before 999.
Also, MyDate tag has date in format "01/31/2011" (mm/dd/yyyy) and it seems that sorting is wroking fine for date. Would sorting by date always work even when dataset table MyDate column is of type string (assuming that my above statement is correct)? Are my two above assumptions correct?
stream = New System.IO.StringReader(XML data returned from web service)
With dataset
.ReadXml(stream)
dvView = .Tables(0).DefaultView

Dataset's ReadXML() method would read an XML document. But how would we skip certain columns? [Code] So, if I use ReadXML(), it would read the whole document and the dataTable would have "id" column, "name" column and "price" column. But I want to have only "id" and "name" column. How can I skip certain columns from reading it?

i am getting the xml using readxml method. And then display the data in datagrid. But number type columns comes as string type in the dataset. So when datagrid displays , sortingdatagrid columns is not correct. For example it sorts like this:
Salary
1180
12133

I have a problem with the function below. If anybody knows of a simpler way to accomplish the same results,The problem that I have with this function is that sometimes, not always, it keeps the Excel process running and when this happens I can run the function again until I kill the Excel process manually.
Another problem with this function is that it is slow if the Excel sheet contains a lot of data.
And also I can't get this function to read all the sheets in the Excel workbook and put the contents of each sheet in a separate data table in my dataset.

I have a project to import data from one worksheet into database SQL Server 2008 on Windows Server 2008 using Interop. The project in debug mode works fine, but accessing the site from a client computer, I am getting permission denied message to the file I'm trying to import and it is located on the server. I wonder what it takes to make additional settings, as well as file folder. IIS? DCOM?

I created an e-mail program in VB2008. I have an excel file with a list of all e-mail addresses and attachments to those e-mail addresses. What I want to do is import thethe e-mail addresses and attachments into my program. I want my program to then take each e-mail address (automatically) and insert them with their attachments into their respectable fields in the program. The primary objective is to insert 200 e-mail addresses and attachments. Each attachement is significant to each e-mail address.

I have read and googled a ton of xml documentation but haven't quite gotten an answer to what Im trying to do. I am trying to create an XSD document that generates explicit type definitions for fields in the dataset. I am then trying to create a sample XML document that validates against the XSD document.
This works fine inside of visual studio because I can read in the schema and the document and it validates BUT, the xml document created has no real reference to the XSD via xlmns or other method. If I want to use this xml data in say MS Excel and I try to import it doesn't know where the XSD is to validate against so it assumes it based on the values. Is there a way in my code to add the xlmns to both the XSD and XML if that is what is needed to solve this? [Code]

I have tried everything I can to get beyond this error which shows below as <<<<< error here. It is trying to fill a dataset from a data adapter. If I change the SELECT statement to just SELECT * FROM xTable I get the correct number of records in each table. But anytime I try with a more complex statement I get the error message shown below which indicates System.Data.Common.DbDataAdapter.Fill(DataSet dataSet. I've completely erased all data and entered a new set of test data so I know there is no problem with relationships. Each table has primary key which is foreign key in other table. IS there something wrong with the Imports section: Imports System

I have designed an application for a company which has 5 client computers that read and write data to an sql2008 instance on a server.I would like to know the way to detect a change in a table whithout having to refill the table adapter.Let's say that all the client applications have a datagridview on the main form which binds to a table on the database lets say Members table (members binding source)Whenever a client makes a change to that table (lets say that it updates the Last name of a member) i would like the rest of the clients to detect that update and as a result ,update the specific row or cell in the datagridview.Is there some kind of event that is raised?

I have two Datagrids, One grid has all the customers garments on it with style number and contact length. The other grid has the users who have garment issued to them. the style number is in both grids. I need to loop through the users grid and say if the contract number is 1 from the first grid then the contract date on the second grid will be todays date + 365 days (year contract) I have looked at using a stored procedure and also a for each command but I am just getting stuck with it all.

I have an application has a data entry form, and currently I'm using the form validation and validated events to validate the data - along with an error provider. I've read that this logic should be placed in the Dataset rather than the form. To that end, i've started exploring how to do that.

I have a class that implements IXMLSerializable. With this interface comes WriteXML, ReadXML and GetSchema. I've noticed that the ReadXML implementation crashes beyond repair (i.e hangs indefinitely) while deserializing when the XML Data is incomplete.[code]

I have developed a program that tracks expenses for business trips that uses just a local SQL CE database on the user's pc. I chose SQL CE because the install process was much quicker and easier than Express. I have distributed the solution and I am looking for a way to allow users to backup and restore the data. I though that the readXML and writeXML methods from the dataset sounded like a good method, but I can't get it to work. I have tried a couple methods which have ended in either foreign key errors or not being able to keep the same primary keys as when the data was exported using readXML.
The basic structure for the data is:SQL CE Database -> DataAdapter.Fill -> Dataset -> Displayed to user through binding sources and other means The problem is not exporting the dataset with .writeXML, but getting the data back into database. The one shot .updateAll from the main table adapter creates foreign key failures, so I have reverted to iterating through the dataset and sending one row at a time, but I still can't get it to work.
