If a class exposes an event, and another class subscribes to it, then where those classes come from is irrelevant.

Events are only detected on Windows Forms. So you can pass whatever action you want to your class library from your Form's raised event. Dont worry about the class library being unable to handle events.

Allow the Form to do that.

Live in fragments no longer. Only connect.

MIME and DIME with Web Services

Hi.

This one is realy nasty.

Does anybody know if there is a free .NET library for handleing MIME messages(used for SOAP attachments)?
I'm accessing a java-powered web service and I need to send attachments to it. The standards it supports for receiving atachments from clients are MIME and DIME. However, there are also functions that send files from the service back to me. And here is the problem: THE ONLY FORMAT USED BY THE SERVICE FOR SENDING ATTACHMENTS IS MIME. AND .NET HAS NO SUPPORT FOR MIME. So I get exceptions when getting the response from the server.

Is there any way to work with MIME in .NET??

Thanks.

You want to find the textbox control ? There are windows APIs for that, you can PInvoke them in C#. I think it's WindowFromPoint, or something like that.

Can you give me some sample code? please!

Christian Graus15-Jan-07 22:40

Does google not work where you live ? The API just takes a point ( well, an X and a Y ), and it returns a HWND ( so, what's returned needs to be an IntPtr and you create a control, and set the Handle property to be the return value, to get a instance of the control.

If you google for C++ help, then you'll find all the help you need, if you add the bits I just told you.

You know, just because we know how to find info, that doesn't mean we've used this API. I've never written C# code that uses WindowToPoint.

how to access a sub item of a ListView control??

Re: how to access a sub item of a ListView control??

15-Jan-07 21:22

hello
i'm stuck on the problem of accessing the sub items of a listview control. the values of sub columns are not being accessed.
i'm using the following code

private void ColumnList_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)<br />
		{<br />
			ListViewItem selection = ColumnList.GetItemAt(e.X, e.Y);<br />
			if (selection != null)<br />
			{<br />
				MessageBox.Show("Item Selected: "+selection.Text);<br />
			}<br />
<br />
		}

how ever the following code only accesses the values of the left most column only.

how do i access the values in sub items.

plz do reply.

The item has a sub items property, you can iterate over that.

through the sub item property, items can only be 'added, cleared or removed' and those too only statically.
i want to access the values of the sub items at runtime when the mouse is pressed down on a value.

how can i do this?

I don't see the issue. The ListViewItem class has a SubItems property. lvItem.SubItems[1].Text will give the text of the second item, for example.

Re: how to access a sub item of a ListView control??

15-Jan-07 22:22

well
u can do it ur way but i don't want to give a specific index to lookup its value statically.

i want to give the index od the subitems at runtime, choosing the value of the index by clicking with the mouse on the respected cell of the listView subitem.

can u guide me about it?? Unsure | :~

Christian Graus15-Jan-07 22:29

Re: how to access a sub item of a ListView control??

15-Jan-07 22:29

OK, then you need to work out the subitem from the point that was clicked, that's another problem. I'm sure it can be done, doesn't the control expose it's column list, with widths ?

yes the control does expose its column list with widths but i don't need those column widths.
i need to work out a way to give the mouse focus on the rows of the subitem and their different cells.

Of *course* you do...

			ListViewItem selection = ColumnList.GetItemAt(e.X, e.Y);<br />
<br />
This is your code.  It finds the item, right ? And you need to find the subitem, right ? So, you walk along the column widths and find out which one contains e.Y, that's the one you need.<br />

the code i posted does retrieve the selected item for only those columns which are created through the code

ColumnList.Columns.Add();
however for items inside the sub items cannot be accessed through this code. Mad | :mad:
