what is .ocx file and .exe file? where is the site that i can get that file tnx!?

Answer 1

.ocx is short for OLE Control Extension, it is an independent program module that can be accessed by other programs in a Window's environment. OCX controls represent Microsoft's second generation of control architecture, the first being VBX controls written in Visual Basic.
Both VBX and OCX controls have now been superseded by ActiveX controls.

.exe is an extention for executable file in windows envoirment. It can be seen in programs such as setup file of any software.

u can easily get .tnx file from www.microsoft.com
search for tnx file and download it as .zip

Answer 2

.ocx is a file used in the ActiveX.
.exe is a executable file used to make a program run.
You need to know what the filename you need is. Example is Process Explorer. It a very simple stand alone program. Procexp.exe
If, you wanted this program then you would do a search for; procexp.exe
The search returns Sysinternals; http://www.microsoft.com/technet/sysinternals/default.mspx and I can go there and find the zip file to download.
