hi, ok this maybe a stupid question, but from what i understand from the above posts, that if i use this command it will tell me that the column has been assigned in the dataset for the datatable when it read in the xnl file?<br />
so lets say there are 5 rows in the dataset, and column1 has 4 number values and 1 string value, would then the above command return as a string datatype?<br />
<br />
then what datatpye do i declare and assign this function to so i can see the datatype?<br />
thanks

Hi,<br />
<br />
I simply need to test the datatypes in a datatable in my dataset in vb.net.<br />
I need to check that there are no invalid values in my total columns.<br />
I am reading in an xml file into a dataset, does it automatically assign the datatype to the coulmn based on the values in the xml file?<br />
<br />
<br />
thanks allot

how to check data type in dataset

Visual Basic .NET (VB.NET) is an object-oriented programming language implemented on the .NET framework, but also supported on other platforms such as Mono and Silverlight. Microsoft launched VB.NET as the successor to the Visual Basic language. Though it is similar in syntax to  Visual Basic pre-2002, it is not the same technology,
