Important function in x++ for AX 2009 and AX 2012

Important function in X++

I would like to share some important function in x++ Like subStr(), strCmp(),strDel() , strFind (),strfmt () ,strLen (),strLwr (),strUpr (),strRep(),systemDateGet(),today(),trunc (),boxExample (),conins(), conLen(), conPeek(), conNull() which seems to easy but some time became very tough to recall in between to coding, so don’t worry and keep coding…….

Rounding in X++

I recently had to do some rounding in X++ on a real variable. This was due to some custom Rebate code. Anyway, I have some sample code here for rounding. I found it strange really how the synatx had to be and could not find anywhere on the internet what the synatx needed to be, so here you go:

server static void RoundExample(Args _args)

{

real r = 7.8413;

real a;

;

a = round(r,0.01);

r = a;

}

Anyway, if you put 0.00 in the decimal, then no decimal is used, but if you supply 0.01 in the decial variable then it works great. So if you wanted to round to 0.0000 then you would need to put there 0.0001.

strRem Removes the characters specified in one string from another string.

str strRem(str text1, str text2) where text1 : The string from which to remove characters.text2 : The characters to exclude from the output string.

subStr

Retrieves part of a string.

str subStr(str _text, int _position, int _number)

where_text : The original string._position : The position in the original string where the part to retrieve begins.

_number : A signed integer that indicates the direction and number of positions to retrieve from the original string.

If there is a minus sign preceding _number, the system selects the substring backward from the specified position.

strDel

Creates a copy of a string with the specified substring removed.

str strDel( str _text, int _position, int _number)

where_text : The string to copy from_position : The position at which to begin ignoring characters during the copy.

_number : The number of characters to ignore.

A minus in front of _number parameter indicates that the (_number-1) characters before the character at the _position parameter are to be removed along with the character at the _position.

strFmt

Formats the specified string and substitutes any occurrences of %n with the nth argument.

str strFmt(str _string, …)where _string : The strings to be formatted.

example: to set the number of page in a report :

Display STR 20 pageNum()

{

return StrFmt(“@SYS24160″, element.page());

}

num2Str

Converts a real number to a string.

str num2Str(

real number,

int character,

int decimals,

int separator1,

int separator2)where: number The real number to convert to a string.

character The minimum number of characters required in the text.

decimals The required number of decimal places.

separator1 A DecimalSeparator enumeration value.

separator2 A ThousandSeparator enumeration value.

Example

static void Job_Num2Str(Args _args)

{

real realNum = 0.1294567890123456777; // 19 decimals places.

;

info(Num2Str(realNum,0,16,1,3)); // 16 decimals

info(Num2Str(realNum,0,17,1,3)); // 17 decimals

} Round Rounds a real number to the nearest multiple of another real number.real round(real _arg, real _decimals) _arg The original number.

_decimals The number that the value of the _arg parameter must be rounded to a multiple of.

Examples:round(123.45,5.00); //Returns the value 125.00.

round(7.45,1.05); //Returns the value 7.35.

round(23.9,5.0); //Returns the value 25.00;

round(26.1,5.0); //Returns the value 25.00;

strLen

Returns the size of a string

int strLen ( Str _text )

ConPeek

Retrieves a specific element from a container.

anytype conPeek(container container, int number)Example:static void conPeekExample(Args _arg)

{

container c;

int i;

;

c = conIns(["item1", "item2"], 1);

for (i = 1 ; i {

print conPeek(c, i);

}

pause;

}

strUpr

Converts all the letters in a string to uppercase.

str strUpr(str _text)

static void strUprExample(Args _args)

{

print strUpr(“Abcdd55EFGhiJ”);

pause;

}

strLwrConverts all the letters in a string to lowercase. str strLwr(str _text)

static void strLwrExample(Args _args)

{

// Returns the text string “abcdd55efghij”.

print strLwr(“Abcdd55EFGHIJ”);

pause;

}

Units We use it to set the unit of a dimension.Example : element.design().controlName(“CustInvoiceJour_InvoicingName”); CustInvoiceJour_InvoicingName.top(20.8, Units::mm);

Global::dateEndYr Method

client server public static date dateEndYr(date transDate)

Global::DateMthFwd Method

Adds the specified number of months to a date.

client server public static date DateMthFwd(date transDate, int qty)
