How to use Corflags tool of Visual Studio to check 32/64 bit of dll ?


Hi

Corflags is the inbuilt tool of Visual Studio which is used to find out the type of .dll i.e 32 bit, 64 bit or any CPU. This tool is available in Visual studio 2005 onward. i.e. VS 2005/2008/2010/2013

These are the following steps to check in Visual Studio

Step1 : Go to visual Studio command prompt like this

Step 3: Go to the file Location of DLL and type the syntax like this in below image

This is the short summary to determine the type of dll

Any CPU: PE = PE32 and 32BIT = 0
x86 bit: PE = PE32 and 32BIT = 1
64-bit: PE = PE32+ and 32BIT = 0

I hope this will help to some body.
