I have one custom indicator using a dll. That works fine
I also have one EA using a related dll. That works fine too.

But when both the indicator and the EA are runing at the same time I get:
cannot load library 'test1.dll' (error 126)

Error 126 is not documented in the stderror.mqh file. What is this error?

Thanks.
 
126 is operating system error and documented in the MSDN (Platform SDK - Win32 API - Reference - Error Codes - Win32 Error Codes)

126 The specified module could not be found. ERROR_MOD_NOT_FOUND
===
some component may be unavailable
Use "depends.exe your.dll" for investigation
 
Thank you Slawa. I will check this :-)
