Ya sir i have done all things which required even i run that code on x64bit machine as well as x86 and also on x32bit machine but it is not working.

when you run your script, if you go to the expert tab of the terminal window, what is the error code?

cannot load library 'ClassLibrary1.dll' (error 126) this error.

mt4 can't load your library because you have the wrong name or it is not in the right folder. make sure that your dll is in the folder named "library" inside the "expert" folder. make sure that the name of your file.dll is the same in your script and in the folder. it is probably not classlibrary1.dll.

i have your code running smooth on my mt4.

sir i have also save that classlibrary1.dll in to right folder and also calling with right name but yet showing the same error.

sir can you come on skype or on gtalk and run code on my machine
