Containers :
- Containers are used to store different datatypes
- Max columns in a container - 50
>> some important functions :
conlen - gives the length of the container
conpeek - gives the value of an element based on the index
conpoke - used for replacing any element with new element value
condel - willl delete the elements in cotnainer based on the start postion and number of elements to be deleted
connull - will empty the container
conins - will help to insert new elements to container
conview - to viuew the elements in the container - onyl for unit testing
confind - to find a particular element exists in container - it will give u the postiion/index
>> Just look at the following example to undestand how these methods can be applied :
static void TDS_Containers(Args _args)
{
Container con = [1000, "Rahul", 5000.00, 56];
container resultCon;
int i;
int position;
// container limit is 50 columns
;
// container index starts with 1
// to get the length of the container
info(int2str(conlen(con)));
// to get any value based on the index use conpeek() function
info(conpeek(con, 3));
// to get all the values in one shot
info("__________________________________");
for ( i = 1; i <= conlen(con); i++)
{
info(conpeek(con,i));
}
info("__________________________");
resultcon = condel(con, 2,2);
conview(resultcon); // this should be only used for testing purpose
// to nullify to empty the container
//con = connull();
//info(int2str(conlen(con)));
//
// To insert any new valuezs into container - use conins()
// To replace any value in the container - use conpoke()
// to find any value in container- use confind
position= confind(con, "sreedhar");
info(strfmt("sreedhar is found at %1 position", position));

Macros in Microsoft dynamics Ax
Macro :- Macros are reusable components
- Macros are mostly used to remove hardcoding and for constant values
- Macros are pre-compiled/FASTER
- In AX, we have a macro processor
- Macros cannot be debugged
- Macros reduces line of code/optimizes the lines of code
- Macros will not end with semicolon
Macros can be defined in 3 ways :
1) Local Macro
2) AOT Macro [Global macro - we can call it in all objects, tables, forms, jobs, reports etc]
3) Macro library
1) Local Macro :
Local macro is a mcaro which is local to that function and cannot be used outside the method/function
static void TDS_LocalMacro(Args _args)
{
#define.pi(3.142)
#define.name('Tony')
#define.address('SR Nagar, Hyd')
;
info(strfmt('%1',#pi));
info(#name);
info(#name + "is a bad person");
info(#address);
}
2) AOT Macro :
AOT Macros will help to resue the functions inside it.
>>Go to AOT >> Macros >> Right click on the Macros node >> New Macro >> rename it to TDSAdd 4 functions inside the macros by doubling clicking it
#define.college('SR College')
#define.age(30)
#define.inst('Vertex soft')
#define.cl(4000.00)
>>How to call AOT Macro
>>Create a new job as shown below
static void TDS_CallAOTMacro(Args _args)
{
#TDS
;
info(#college);
info(int2str#age));
}
>>How to use in any other object:
Go to TDS_CustTable >> Methods >> Override initvalue() method and paste the following code
public void initValue()
{
#TDS
;
super();
this.Creditlimit = #cl;
this.JoinedDate = systemdateget();
}
3) Macro library :
Microsoft has already given many macros in AOT >> Macros node
[sys] layer
we can go ahead and add any function to already existing macros [sys layer]
AOT >> Macros >> AOTExport >> open in editor and add a new function at the end
#define.marks(30)
How to call Macro library macro
static void TDS_MacroLib(Args _args)
{
#aotexport //#macrolib.aotexport
;
info(int2str(#marks));
}
How to pass values or nuMber of lines in Macros: possible
static void TDS_PassingValues_Macro(Args _args)
{
int c;
#localmacro.sum
c = %1 + %2;
#endmacro
;
#sum(10,20)
info(int2str(C));
#sum(1000,5466)
info(int2str(c));
}
Macros reduces number of lines of code as well
static void TDS_PassingValues_Macro(Args _args)
{
int c;
#localmacro.sum
c = %1 + %2;
c = c - 4;
c = c * 4/100;
#endmacro
;
#sum(10,20)
info(int2str(C));
#sum(1000,5466)
info(int2str(c));
}
Note : It is best practice to use macros only to define constants. Also TDS stands for Tushar Devendra Srivastava just using my initials as best pratice for creating my own customizations.
