Application Error... When querying data

P: n/a
Hello,

Not sure how to give a quick explaination, but...

I have an application which queries a proprietary archive. I do this
using OLEDB with datasets and OLEDBDataAdapter. I am making about 500+
queries, which bring back 1 piece of data as quickly as possible. I am
querying the data using a method of a class.

Example,

iHClass.ReturnCalculated(string StartTime, string EndTime, string TagName,
string CalcType)

It is a bit of code, so I won't duplicate it here...

But, I am calling this method of the iHClass from a form button. In the
button, I call this method MANY times. I get an error accessing memory, but
never during the same call or even at all sometimes.

I have no idea how to track this down or what might be wrong...

Here is the error:

The instruction at "0x000000000" referenced memory at "0x0000000". The
memory could not be read.

It does this several times and sometimes says '.... could not be written'
and gives a different memory addy.

Ideas??

Thanks in advance,

Andrew Mueller
