This code does not compile correctly any more.  Complied with the December 2018 build, but not on any build after. 

'RegressionCalc' - unexpected token, probably type is missing? Regression.mqh 48 13

'RegressionCalc' - function already defined and has different type Regression.mqh 48 13


Suggestions?

Functions which doesn't return a value need to be of void type.

thank you.  

That must have change with a recent release, because I have been running that code for some time.

Will make the changes and carry on.

I'm using build 1220, and now the "//" comment can't use for showing the input :

input string      S1                = "";             // --- Searah Trend ---
input bool        UseTrend          = true;           // Pakai OP Searah
input double      TrendGap1         = 20;             // Jarak 1 dalam point (Searah)
input double      TrendLot1         = 0.15;           // Lot 1 (Searah)

It still show the original text

Also when using same variable outside the { }, it will show error when compile the code :

Hello

Did you see that the new version of Terminal.exe (MetaTrader 4 Client Terminal build 1220) gives the following windows errors:

these error messages did not occur with the previous version of terminal but my broker impose the new version!

Do you have a solution ? thank you

I saw on another forum an explanation of this error:


"This error is caused by a wrong manifest embedded in the FormDesigner application. If you open the application in Visual Studio and extract the manifest you will see two references to the common controls dll - one processor-agnostic (*) version and one version requiring x86. On a 64-bit machine processor-agnostic references will appearantly resolve to the 64-bit version. The error in the event log is legitimate since imports are already defined from whatever version was process first. To test just try removing the processor-agnostic reference from the manifest and resave the app in Visual Studio. When you rerun the app the errors are gone."


but it is impossible to modify terminal.exe !!!
