Hello
I am searching for a method to capture an area of screen to a media file with an extension (*.wmv). Microsoft already provided a tool for said purpose such as Windows Media Encoder 9. But the point is I want to achieve that without utilizing Windows Media Encoder Services / Software / Tool. Any help in this will be highly appreciated and Please feel free to share your ideas.
thanks.

This get's asked about every 4 months...
There is no reliable method of doing this. You'd have to use some OCR methods to actually attempt to read the screen. Different fonts will throw off the OCR's ability to read the text though...

Nope. Nothing will give you a consistant interface to do this.

You need an external service to do this. Basically, you have to time the download of a known large file from a known source that is relatively close to your machine on the Internet. There is nothing you can query on your local machine to find out what the Internet connection speed is.

You can probably use WMI and the System.Management namespace to get a collection of Win32_NetworkAdapters. You can then try checking out the Speed and/or MaxSpeed properties to get what you want.

If you want to do it the hard way, feel free! The WMI Win32_NetworkAdapter, Win32_NetworkAdapterConfiguration, and Win32_NetworkAdapterSetting classes will give the the same information without P/Invoking the Windows Network API to death.

Hello ppl
Assume I have a ListView containing 5 columns. For a particular reason I'd like to be able to read the subitems of column 5 (index 4) into an ArrayList or a common array. I've tried different approaches, but the listview and I don't hit it off. Can somebody please give me code example of how this can be accomplished?

OK, I'll answer my own q. Here's one solution for those of you who have gotten into trouble with the mighty listview class...
For i As Integer = 0 To Me.MyListView.Items.Count - 1
Me.MyListView.Items(i).SubItems(5).Text
Next
'Where 5 is the index of the sixth column

You didn't sned the contents of your ss variable. You sent the string "ss" to the other app (without the quotes).
The line should look like this:
SendKeys.SendWait(ss) ' no quotes!!

Hi
I want to work with data in an excel worksheet in my vb6 program, but I don't know what to do...
Could anyone introduce me a tutorial?
Thanks

What do you mean by working with Excel from vb6? Do you just want to display only data on the form or display it in any control and you could edit its data? But first, try to check from google search result.[^]
