ReadXml fails please help

[Rainer Queck]

Hello NG,

I am using a typed DataSet, created with VS dataset designer.
I have the problem , that a table in the dataset refuses to read a xml file.
The strange thing is that if I create a seperate datatable, using the Typed
DataSet.Table this reads the xml file without any problems:

To make it a little more clear:
public class MyClass
{
....
DsMyDataSet myDataSet; // gets initalized in the constructor

....... some when at runtime this method is called ....
void MyReadFromFile(fileName)
{
myDataSet.myTable.ReadXml(fileName); // fails to read the xml
fail, table has 0 columns
DsMyDataSet.myTableTable tbl = new DsMyDataSet.myTableTable tbl();
tbl.ReadXml(fileName); // works fine, that table holds a bunch of
rows.
}
}

PLEASE HELP. What is it that I am doing wrong?

Regards

I would start by removing any constraints .. like "primary key"
ones....while you're in the dataset designer.

And when you find the magic constraint that is killing you..you can figure
out your plan of attack for it.

This is a total guess.....please look at others who post ideas as well.
