Use LINQ?

var list = new int[] { 1, 2, 7, 8, 3, 5, 8, 8 };
		
var query = from i in list

Just write the code to try opening the port. If you get an exception, it's not available.

Using OCX control in C#

Hi,

My project has layered architecture. Business logic has separate project and in this project I have to use some registered OCX method.

Current situation:
In presentation layer I have window forms. It is easy to add OCX control in toolbox and draw it on any form. Object of drawn OCX control can be used for calling its methods. But I don't want to do it in presentation layer.

I have following question:

Should I manually add reference of OCX in business logic project? If yes then how I can use it in cs files?

Please tell me how to call method of OCX without having forms. That means no creation of control at design time.

Thanks.
Hassan Nisar

You probably need to create an interface which exposes few methods that acts like facade methods. This methods should eventually call the methods on the control. With this, your business logic project will not be aware of the OCX controls. You can inject this interface instance into your business classes from the presentation layer.

Best wishes,

I am using the code at the botoom to generate the monthly contracts invoices and save every invoice as a separate PDF I am generating all invoices to have the same GUID so it will be easier to retrieve all but it will be more than one invoice so for example they will all have same GUID but I will have 5 or 6 companies. I want to use the same code below to generate the separate PDFs using the invoice_number as file name.

Basically you need to create a column and add it to the columns collection. As far as it's duty, I have no idea what you are talking about!

Additionally i want a gridview that has a deleting ability and i want to add this ability to my datagrtidview in code.

Well, in my applications, selecting the row header and pressing the delete key deletes the row. If you need something different, then maybe using a checkbox or button column and doing the delete when that is selected would work, but it seems convoluted to me.

Or maybe I still don't understand what you want to do?

Hi,
add a ButtonColumn to DataGridView and name it like Colremove
then write code for dataGridView CellContentClick event like shown below

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
    if (e.RowIndex > -1)
    {
        if (e.ColumnIndex == dataGridView1.Columns["dataGridView1.Colremove"].Index)
        {
            dataGridView1.Rows.RemoveAt(e.RowIndex);
        }

    }
}

Circular Dependancies!

Hi all,

Design question, I have three library projects, A, B and C.

Project A - error logging class
Project B - properties class with static methods
Project C - eventing class with static methods

Unfortunately, I want project A to use the properties class B, B to use the eventing class C, and C to contain an error logger object, resulting in a circular dependancy:

A <<uses>> B <<uses>> C <<contains>> A

How can I get around / redesign this? I'm a bit of a novice and might be missing the obvious but I don't see how I can use an interface, as C contains an error logging object, it is not passed an error logger as a method parameter.

Thanks in advance, am so confused!

Re: Circular Dependancies!

Combine C & A or B & A. That's the simplest way. By combine I mean either the whole project, or just the code that relies on the other reference.

Assuming each project doesn't really contain a single class - move the class that is offending out into a fourth project - that can then be referenced by the others as necessary.

But it could be... it could be. Cool | :cool:

Or why not as a constructor parameter? Or, if it's not required, perhaps as a property?

And what is an "eventing class"?
