Help Needed with Passing a Variable Name

[behr 10]

I am new to EL and was hoping someone can direct me:

 

I am not sure how to pass the Variable name form EL in Multicharts to a DLL routine. I cant see any routine which gets the name.

for example if iam trying to call the following DLL from EL:

 

void __stdcall MyArraySort( IEasyLanguageObject* pELObj, char* MyArrayName ) // example form MC/TS SW dev kit

 

my easylanguage code is:

 

Function Code:

 

EXTERNAL: "example.dll", void, "MyArraySort", IEasyLanguageObject {self}, LPSTR {myArrayName};

 

variables: index(0);

 

arrays: myArray[11](0);

 

// fill array with some data

for index = 10 downto 1 begin myArray[index] = 10-index;end;

 

// call MyArraySort

MyArraySort( self, myArray);

 

 

with the above code i get the wrong argument type...

 

Thanks for the help

yes i have read the manual. It basicaly says to pass the variable.

obviously i am missing something as my EL code does compile. The DLL builds ok... as i have tested it with other routines...

This is the DLL Function Declaration Statement in EL.

 

Syntax:

DefineDLLFunc: “DLLNAME.DLL”, Return Type, “FunctionName”,

Parameters ;

 

Examples can be found in the EL Reference Guide in Chapter 4.

The EasyLanguage Extension Software Development Kit states:

 

The EasyLanguage analysis technique that calls the DLL function must

declare the DLL function in an external statement. This requirement

applies to the DLL only if the DLL uses the SDK. This is not a

requirement of DLL’s that do not use the SDK. If the DLL does not use

the SDK then either the external reserved word or the legacy

reserved word DefineDLLFunc may be used to declare DLL functions.

 

I have tried it with the DefineDLLFunc and i get the same problem.

- compile error code:: incorrect argument type

behr,

 

Sorry but I haven't used the SDK so not sure there. I seem to vaguely remember running into an issue using LPSTR in the past but don't remember the circumstances. Maybe you can create a simple integer add call or something just to get the interface working.

I have a routine that passes a value and that works fine.... just having problem with the array that needs a variable name.

 

thanks
