Hi,

I coded a DLL in Visual C++ and placed it into experts\libraries directory.
Now I want to code an EA in MT4, but the following code gives me an Error:

#import “TestDLL.dll”
   int Sum(int a, int b);
#import

The error: ‘import’ - double quotes needed

I already googled, but didn’t found an answer.
Do you have one? Thank you very much in advance!
Kind regards feuerfuchs

I found it, what a stuipid error. I copied the text from somewhere. Obviously there’s a difference between the signs " and the used sign ”.
I replaced it and it works now. :slight_smile:

MQL4 is painful like that. Haha :stuck_out_tongue:

Hope everything is working fine now. :slight_smile:
