What exactly did you do with iframe? Can you give us a few lines of code?
Most IP cameras are able to stream the video (access through a special port / web interface of the cam). So what you have to do is to manage the stream, i.e. get a snapshot every second, save video sequences and so on. I think you need some code behind, if you want more than just display the live picture.

was very helpfull to me ...
... hope it will help you too.

the barcode scanners I used since are some kind of 'programable', that means you can configure the codes they accept and send extra items ('Ascii-codes') before and after the data that the scanner has read. I've never seen a barcode scanner without some kind of 'keyboard-mode'.
I.e. set the scanner to accept only 2of5, send 'abc'<2of5code>'xyz'.
so the only thing your app has to do is to whatch out for 'abc' to jump to the right inputbox. setting 'xyz' to "tab" or "enter" triggers the validating process of your inout box.

coding (logic, rules, etc) is upon you !!!

I don't think that theres a problem with the SQL-statement. I guess it's in parsing the delivered dataitems or in the mapping of the the table's structure. Which language do you use? What is 'GetImportRateTableDetails' ?

do I get you right if I state this is the result you want?
series SLPNAME U_AltProfile U_INRPRICE LINETOTAL TOTALLINETOTAL
223 Janet 0 NULL 2132.500000 2350317.5
223 Janet 0 NULL 4650.000000 2350317.5
223 Janet 0 NULL 2343535 2350317.5

I'm missing some "group by" in your SQL. Is SLPNAME your primary key?
Why do you select more 'columns' as you need in your resulting table?

mmhpf. your code is missing a lot of information
- there is some kind of counter (i) but no loop
- if you want to "load" your data from the table into the grid, you better use databinding, but I'm not clear about the if condition in your code ...
- you do add a new row, but don't write any data to that new datagrid row ...
so we do need more input to help

the paremeter"xyz" instances are not bounded to the report nor to the dataadapters fill method - so it has no effect ...

google has a quite good api documentation with a lot of examples.
most of the interaction can be done using http referers - try this as a starting point for your studies. have fun!

please check the following issue:

if fd.send() is asynchronous the fs.disconnect() may destroy the server before the sending has completed ...

as Andy Lanng said, there is no solution/algorithm to do this automaticly, and that can bee proofed
all you can do is manually create a table/ressource plan and let the program test, if it is valid and in the next step, if plan is complete you can make some changes and test again ...

don't know if I realy understand what you try to do here

if dynamic means that you don't know many columns you have, recursion will be a idea (if the columns are still few) if only one of your sets has an extra column you just add it to each result of the "matrix", but what's the result if two sets have an extra column?

permutations: there are n! = 3! = 6 (4! = 24) for each of your sets ...

You cannot directly access a class in the calling form from the outside easily, imagine what will go on in your "mainform"-class after you call your "inputform"-class - you never know. The "back-call" that you're planing to implement is not threadsafe.

I think there are three ways to solve the situation
1. scope to threading (slightly pushing it)
2. use events/messages (my favorit, not very difficult to understand)
3. do it in one form (hide/show input area, resize the form for your needs - the dirty way)

C# in a nutshell (o'reilly) may help with the details

thx for your answer - of course, you are right !!! (If someone's running out of logical conclusions ...) I don't deal with threads in the current project.

Nevertheless I'm clueless about what went wrong. It's a simple string that I add to my CMS .
And: before Application.Run() it works.
Any idea?
