#include <somelibrary.mqh> doesn't work on Library Studio

[kketzal]

Hi:

I'm using Library Studio to write own custom blocks.
When I try to #include some MQL4 standard library in "Global Variables, Includes" Area, the MQL4 code generated shows some errors.
For example, if I include:

#include <Controls\Dialog&#46;mqh>

Then, the MQL4 code I can see is:

#include Array

There are any workaround o solution to this? I know Library Studio is being used only by 3 or 4 "mad men", like me.

Reuploaded under the same build number, so if there are problems - tell me.

I don't know how it will be on your side, but I got error messages somewhere in Chartobject.mqh file ("cannot convert enum"). If you have them also, add (ENUM_OBJECT_PROPERTY_STRING) before OBJPROP_TEXT so it will be like this:

//--- result
   return(ObjectGetString(m_chart_id,m_name,(ENUM_OBJECT_PROPERTY_STRING)OBJPROP_TEXT));
  }

I don't understand this one.
What do you mean?? To delete my custom block and rewrite it and then change the block number to the old one??

Yes, I have the same error. I try your solution.

Ahhhhh....ok, sorry. You have uploaded a new fxDreema build, with the same version number....it's true?

Ok, now I can include MQL4 Standard Library MQH files with no errors...but I've other problems:

Problem 1 - Global Variables like this:
```
CArrayString *arrayGraficos;

     whe I make a MQL4 file, this global variable is assigned to 0, like this:

CArrayString *arrayGraficos = 0;

Problem 2 - And when I try to compile the program in Fxdreema, some errors are displayed:

[fxDreema]

I don't remember why I decided to add " = 0;" to global variables that does not have value, but I think now with the new MQL4 there will not be a problem for those variables to not have value.
Reuploaded again with this thing fixed.

More details about the last error? Maybe some link to a file to be included does not exists?
Does MetaEditor reports the same errors?

In MetaEditor works fine. I test 2 EA and same errors are shown. I change to other computer and I think the error is about "Program Files/MetaTrader" or anything in that way.... This error is with new rebuilds uploaded, maybe.

[fxDreema]

You used that "Program Files/MetaTrader" somewhere in the project? Give me some more details, what is on the picture is... I have no crystal ball Some .mq4 file?

[kketzal]

Ok. MQL4 file attached.

......
PirateAlarm.mq4

[kketzal]

The same errors are shown with a new fxdreema project with no blocks...

thanks.

[fxDreema]

Opps, wrong command to the compiler. How is it now?

[kketzal]

Ok. With MetaEditor I can compile, so It's not a critical bug.

I have another error with fxdreema code generated. It's only when I #include a custom class that work with graphical components (Dialog.mqh, ComboBox.mqh, etc...). This is the error in the fxdreema code:

......

[fxDreema]

Those warnings.... how is it now?

[kketzal]

Attached 2 MQL4 Files, the last one, and the include file that i think it's doing fxdreema code errors.

Thanks.

PirateAlarm.mq4

mmmm the second file "MiVentana.mqh" isn't being uploaded....I try again with code marker:

Hi:

I think that "undeclared identifier" MetaEditor error can be solved rewriting variables "tt, ask, bid" declaration, like this:

Putting the variables declaration out of the IF code block:

I don't know if you can get side effects in this change.... , but no compiler errors are shown.

[fxDreema]

I think I fixed it already How is it now?

[kketzal]

I don't know...

Other problem with #includes....if I have 2 Fxdreema blocks importing MQL4 Standard Library files in the fxdreema "Global Variables, Includes" area, only one MQH file is imported in Fxdreema generated code...

Fxdreema Block 1 (block put in OnTick fxdreema area):

#include <Arrays\ArrayString&#46;mqh>

Fxdreema Block 2 (block put in OnInit fxdreema area):

#include <Controls\Dialog&#46;mqh>

Only the second one is included on fxdreema MQL4 generated code.

[fxDreema]

Now it must be ok
