You can't.. object pascal is a different animal. You can however make a DLL to do tons of stuff. I also have source to do most of the common indicators in Delphi, but you will need to give it your own bars of data..

1- They don't work in backtesting
2- They don't write outside "MetaTrader 4\experts\files" path.

Today I opened my Visual C++ and wrote a file handling dll for MT4, I hope you enjoy it, and its source code, and tell me your

.

Setup:
1- Extract the "mtguru1.dll" to "MetaTrader 4\experts\libraries" path.
2- Extract "FilesDemo.mq4" to "MetaTrader 4\experts\indicators" path and compile it.
3- Extract "gFiles.mqh" to "MetaTrader 4\experts\include".
4- Load FilesDemo from your Indicators - don't forget to enbable "Allow DLL Import"
5- Enjoy.

Your source code is amazing! However, it does not allow me achieving what I need to perform my trading strategy.

What I need to do is to lunch a second terminal from my expert advisor. However, if I use your code as follows:

int file = gFileOpen("C:\Metatrader 2\terminal.exe",READ);

Nothing happen, and no terminal is lunched. Could you help me with this?

I understand I could do this task with WINAPI OpenFile; however, I am not a programmer and do not know how to declare it in mq4 and afterwards use it.

Best regards,

Andres

Dear All,

I had one EA stored in the folder named "expert" just under MT4, and the required DLL is stored into the folder named "library".

This EA is for automatic trading.

After attach the EA to the chart, it show the error message at the bottom:

"Can not load ...DLL."

Is any expert can tell me where is the problem ?

Carlo

You should have dll file in the folder. If you have it so allow dll (read few posts above on this page).

I was so tired to find where the problem is. I am not the expert as yours.
Really need some expert to help me.

As in the following attachment, I saved the dll in the folder .../expert/libraries

so, where is the problem ?

Don´t you mind to attach the EA to see the code and if we can reproduce the error.

If you can´t attach the code look for some quote in the code like the following and post it.

Quote:

#include <3c_BB_Osc.mqh>

or some line ending with DLL like abcd.dll

Have you checked the name of the dll inside the indicator it`s exactly the same as the dll name?
