Hello!
I have an urgent problem concerning ASP.NET, ADO.NET, SQL Server, XML and
the TreeView control.
I have two tables; one describing the products and one describing their
relationships. A product may consist of multiple other products. So far
everything is great. But one product may exist as a subproduct to multiple
parent products.
My tables:

Hi,
We are in the process of designing an ASP.NET app, where a user will
enter some 'Customer ID' to be queried in the database. If the ID is
valid, several stored procedures will be called to populate multiple
webpages containing customer information. There isn't a one-to-one
correlation between the stored procedure and a webpage. In other
words, a webpage may have to refer to 1 or more DataTables to populate
itself. Therefore, a...

I have my code done to populate a treeview, but when I move it to the
backgroundworker I get an error "Action being performed on this control is
being called from the wrong thread. Marshal to the correct thread using
Control.Invoke or Control.BeginInvoke to perform this action (code to
follow). What am I doing wrong. I moved the LoadWIP function to the
backgroundworker DoWork method instead of calling the sub, but got the same
problem. ...

Hi,
I'm trying to populate a TreeView from an existing and filled in
ListView (lvwBuild). lvwBuild is a basic two column listview which can
have any number of rows. I would like the first column of lvwBuild to
be a node and the second column to be a branch on the TreeView
(hopefully I have the syntax correct). I've been researching how to
do this but have come up empty. I'm guessing that you would fill an
array from lvwBuild and...

Hi,
I have a Winforms 2.0 project that I'm working on that involves populating a treeview control from data contained in a fairly large dataset that has to be refreshed periodically.
I have no problems populating the treeview nodes initially, but am somewhat flustered as to how I should go about keeping the treeview control current with the dataset.
After the dataset has been refreshed, I can, of course, clear the treeview nodes and...

How to populate a treeview from a dataset
I am very new to C#. I need to create a Windows form that will read a SQL table and populate a treeview. I can connect to the DB, create the dataadapter, populate a data set. The problem is how to use the dataset to populate a treeview.
I have looked at a few examples but none use a dataset, or the data structure was different and I could not modify to work with my data or the examples were more...

Hello
I have populated a treeview from my dataset and by clicking in the treeview i want to get the corresponding table shown in a datagridview. Ive managed this by looking at each DataRow and child rows and added the nodes with a columnname from each datarow. At the same time i have put in a tag at each treenode with a filter string and the current table im looking at as a string to use for later so i can create a datatable and set a filter...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
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.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...
