I've been trying to get a custom control working, a DGV and some embellishments, in a DLL. In a test project the new control shows up OK once added to the toolbox, and I've managed to get it to show...

Quick Update
The project is still going strong, and has been renamed Majorsilence Reporting although My-FyiReporting lives on in the URLs involved!...

Simplest way is to have a public variable in the chqdetail form, and set it (oForm.YourVar=whatever) to whatever you require before you show the form.
-
For starters,
Dim oForm As chedetail
oForm = New chedetail()
oForm.Show()
oForm = Nothing
There are various ways to pass data into the new form.

Ah, brilliant, many thanks!
What a great way to play with data, impressive stuff :)

Quick Question, I hope, is there a way to Select from a Select in LINQ?

Is it someone else's database, or your own (as suggested by "tbl1964 is sitting in design mode grid unused") ... so it's not too late to re-organise it?
-
That's the problem with programming, it's like "the blind leading the blind". There's often an elegant and sophisticated way to do something, but unless someone tells you about it, or you read it...

The general idea of a relational database is to NOT have duplicate data in different tables. You put it in one place, and join to it as required :)
-
Are tblEPData2 and tbl1964 joined by particular fields? If so, add this in your WHERE clause : AND (tblEPData2.field1 = tbl1964.field2)
And please explain what you mean by "need to output another...

And whatever you do, beware of SQL Injection. The user could type in all sorts of nasty things in the text boxes that would end up as SQL commands. Use parameters instead.

There's "ideal and proper", and then there's "what's good enough and what he wants to do for his own reasons" :)

You could shell out to a command line to export the required tables, using sqlcmd or bcp -

Try sqlsrv_connect using SQLSrv. Goggle for : mssql_connect sqlsrv_connect

Well at least I can serve as an example of how not to do it, LOL.
I'll get my coat.
Thanks for educating me :)

You could have another datatable and when the Search Text changes, copy the matching rows from the original to the shown datatable (or just unhook the DGV from the original dt and manually fill it...

You can loop around the DGV contents (or the original dataset)...

Try to break down your problems into simple steps, verifying along the way what works and what doesn't, then you'll find where the problem lies.
In this case, try a simple sql query and see if that...

Thanks, it's all very intriguing and puzzling. I thought I had a grasp on it, but now I'm very confused!
I'm keen to see what anyone else could contribute...

Thanks, anyone else care to chip in with more technical detail?

I assume that backwards compatibility is built in? i.e. a .DLL compiled for v3.5 should be ok to use with a v4 project?
I ask because I'm about to play with some Open Source widget and their...

Thanks, I dialled in my key and it seems to have worked, it doesn't say Evaluation any more, and trying the registration option again it says it's already registered. That's about as hopeful as it...

Thanks, it all seems to be behaving itself. Just 4 lines of code (including the End Using) gets me a SQL query result loaded into a datagridview, so I'm happy with my first real class :)

Got it working, thanks.
Example: Add a column to a dataset read from XML, and check all rows for a bad field and set the new "Errors" field :
oDSet = New System.Data.DataSet
...
-
Thanks. Unfortunately the XML isn't mine, it's an export from some other system - hence I'll need to check carefully each row contains valid values before doing anything with it - and alert the user...
-
Aha, sounds like a plan :)
Thanks!
-
Thanks - so I have to manually copy the XML dataset to the DataGridView, so it's unbound - set up the columns by hand, etc - and all will be well....?
