Hello,
We are having a recurring problem of a typed dataset that
we have in a form dissapearing from the VS designer and
all bindings being lost. The dataset is defined in
another component and we reference that component, and
use the dataset designer tool to simply create the
dataset variable on the form. Every so often though,
with no...

Can someone point me in the right direction? Somewhere I read that you
reference a strongly typed dataset as if it were a class structure. For
example,
<SomeTests>
<TestsGroups>
<Group>
<TestName>TestA</TestNmae>
<Test>Run1</Test>
<Test>Run2</Test>

1) I make an exact copy of my "DataSet" and delete one record from a given
table (in the copy)

then I will show my code, which has most of the...

The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it. ...
