Why do you think someone will download who-knows-what from who-knows-where? This site is oriented to questions formulated on a single page using English and some code samples.

Sir, when i import the dll from visual studio i get an error. And since i dont know much of VB i cannot use it directly in VB.
Now i just wanted to know whether i was doing some mistake in using it, or the dll was corrupt. Thats why i linked the dll and ocx files.

AND THE ERROR WOULD BE .....???? (HINT: EXTREMELY HELPFUL!) YES, I KNOW I'M YELLING AT YOU!

Tell us the error message. Also tell us what you did just before you got the error mesage.
Do you include the dll via References-COM or do you create a Primary Interop Assembly and add a reference to that PIA? Do you use a 64bit machine? Does the dll have a specific bit-ness (i.e. built for 32bit/x86 applications)?
