EA download file http - Problem to use a library (libcurl.dll)

[Leandro Oliveira]

I need to make the download of a file in my EA in background mode. Then I searched how I could to do it, and found that could to use a library of curl application called libcurl.dll. Then I downloaded and put it in my program, but the problem I don't know how can I test it, or how can I use the function of this library.

Can anyone help me?

You have to use the #import directive to make calls to the dll file

You might also want to take a look at WebRequest instead of the random dll file you downloaded from the internet.

It is best to avoid using .dll files whenever possible, and use the built in functions.

You must use #import command to execute dll call to dll

You can want to see WebRequest instead of dll files you have downloaded from internet.

Best most most expired is not use any .dll file you can be used and use the integration in integration.

Hi Jack Tomas and Toan Ty,

Thank you so much for yours helps, I solved the problem only using WebRequest() function, this much easier and so efficient.
