How do I tell Visual Studio C# 2005 about a DLL supplied with my USB hardware (motor control - MotorBee). I need to be able to call the functions in the DLL. Is it so trivial that its obvious? (not to me!)

See a previous message[^]
Plus:
chances are your USB dll is not a .NET dll but rather a native code dll.
In that case you dont need references and using, but you need PInvoke, i.e. the
techniques required to call native code.
Lots of examples are available on CodeProject. Prerequisite is some documentation
as to what functions are available in your USB dll.

Thanks for pointing me in the right direction - I will investigate.
Is it only me or does anyone else find the Visual Studio help system difficult to get meaningfull answers from?

Well I am satisfied with Help/Index... which leads to the reference info,
although I often feel I would like each item to have an example;
and I am not impressed much by Help/Search... , IMHO it needs a better search engine.
A useful feature is Help/SyncContents: when in one of the reference pages, it leads
you to the matching location in the Content pane, so you can easily browse
neighbour information.

It is mostly the search I have trouble with. The problem is really me in that I should learn C# and Visual Studio properly. I never seem to have time, always pressure to make something work "quick and dirty".

used to scale picturebox control or form

You can position and size your picturebox any way you want.
You can assign an image to the PB, and finally there is PictureBox.SizeModethat defines
what to do when picturebox and image happen to have different sizes.
When in doubt about some class, first thing to do is read the page(s) in MSDN, the help
information that is built in Visual Studio. (Menu Help/Index... or Help/Search...).

how to create multiple instance of a windows service in the same server.I have to run 5 instance of a single windows service in the same server .Environment is .Net and c#
people laugh at me because they say im different and I laugh at them because they are all the same.
|
|
|
|
|
I am not sure this is possible.
Cant you organize a single service in such a way that it can serve multiple clients at once ?
Can you explain a bit what functionality you want to achieve ? This is likely to yield more
and better answers...
Luc Pattyn

|
|
|
|
Right. Other than that they each need a unique name. It can be done, but there is likely a better way.
|
|
|
|
|
i got the answer.The situation is like we have to monitor multiple server from the single service for perfomance reasons we are using a single service .
people laugh at me because they say im different and I laugh at them because they are all the same.

I need to create, to edit, to eliminate contacts of outlook with the servant exchange server 2003 from an application web (c *.net with framework 1.1).
Since I can do this?
.net

|
|
|
|
Outlook and Exchange Server are not the same thing. They each have there own programmatic interface. Perhaps you should read some Microsoft documentation on each of them.

Hi,
I have a C# class which has a number of properties. I want to create a collection for this class to pass to a method. Can anyone tell me how to do this? There must be a standard way I think.
|
|
|
|
|
Take a look at Generics in .NET 2.0. List<ClassName> or Dictionary<key, ClassName> are probably what you need.
|
|
|
|
|
What is the collection supposed to hold: multiple instances of that class ? the public properties ? or something completely different ?

Hi
I am trying to explain my problem clear enough. I have a dataset DataSet1 which has some data retrieved from the database. I have a copy of DataSet1 called DataSet2. In DataSet2 user are doing some transaction..modifying and deleting rows in a datatable. Now I want to reflect deleted records of DataSet2 in DataSet1.
I tried with "Merge", but it reflects only the modified not deleted records.
Can anyone help solve this?
Thanks in advance
Muthu.

You don't need a second copy of the dataset to track the changes yourself. Each row has a RowState property which tracks this so you can validate / undo / whatever
|
|
|
|
|
Thats right. But in this case, second dataset is generated by another application. So I need to get modified and deleted details of second dataset.
Thanks
Muthu.
|
|
|
|
|
Are changes being made to dataSet1 while changes are being made to dataSet2 in the other application?
|
|
|
|
|
Yes. Exactly. Second application returns the modified Dataset. I want to find out the deleted records for each datatable without using any loops.
Thanks
Muthu.
