I try to work on code on easylanguage to send a image of the charts when a signal is generated by trading system.
The multicharts it's possible save charts as image file, I'd like to send a image of the chart when a signal is generated.
I find easy under metatrader:
WindowScreenShot("shots.gif",640,480);
SendFTP("shots.gif",NULL);
FileWrite()
SendFTP()
FileAppend

Is there any trick to publishing on website a image file of multicharts when a signal is generate.

DLL = Dynamic Link Library

In the context of EasyLanguage, it's an external program with which EasyLanguage can send and receive information. Typically, a .dll is used to add functionality to EasyLanguage.

For example, I wrote a quick .dll using FreeBasic that allows for better random numbers to be generated within MultiCharts. I first wrote the function in FreeBasic that received the high and low number limit for the random number to be generated and then generated the high-quality random number, and then I wrote a function in EasyLanguage that supplies these high and low numbers to the .dll and receives the random number that the .dll passes back.

In your case, you'd probably want to write .dlls that can send emails, take screen shots, etc. How you create the .dll depends on what language you'd want to use - a lot of different programming languages can create them. I first tried with Visual Studio but that was very hard and I couldn't get it to work, most likely because Microsoft's programming tools no longer support the type of .dll technology that TradeStation/MultiCharts uses.

Freebasic allows you to create compact .dlls that MultiCharts can use, and it's not complicated programming. Also, there's a lot of existing code already out there in Freebasic, so you may not have to reinvent the wheel.

I've posted several .dlls in the MultiCharts forums (including the original source code) so you can reference that as you try to get your project going. Good luck!
