CTktFlds

CTktFlds is a C++ class that is a wrapper around struct tktfld_struct to simplify ticket programming.

Constructor

CTktFlds(void);

Parameters

Constructor does not accept any parameters

Examples

CTktFlds flds;

This contructs the object.

Member Functions

Clear

Clears all references or a specified item.

void Clear(void);

void Clear(int nFld);

Parameters

• nFld - Ticket item to clear

Version with no parameters clears all fields

Return Value

Function does not return a result.

Remarks

Examples

CTktFlds flds;
flds.Set(TKT_FLD_TIME, strTime);
flds.Set(TKT_FLD_GROSS, strGross);
PrintTkt(TKT_STD, flds);

CTktFlds flds;
flds.Set(TKT_FLD_TIME, strTime);
flds.Set(TKT_FLD_GROSS, strGross);
flds.PrintTkt(TKT_STD);

// Clear the entire flds object to start over
flds.Clear();
flds.Set(TKT_FLD_TIME, strTime);
flds.Set(TKT_FLD_NET, strNet);
flds.PrintTkt(TKT_ALT);

CTktFlds flds;
flds.Set(TKT_FLD_TIME, strTime);
flds.Set(TKT_FLD_GROSS, strGross);
flds.PrintTkt(TKT_STD);

// Clear the gross weight reference so it will not print on the alternate ticket, time will still print
flds.Clear(TKT_FLD_GROSS);
flds.Set(TKT_FLD_NET, strNet);
flds.PrintTkt(TKT_ALT);

Set

Sets a reference

void Set(int nFld, string& str);
void Set(int nFld, char* psz);
void Set(int nFld, const char* psz);

Parameters

• nFld - Field to set
• str - String variable
• psz - pointer to character array

Retrun Value

Function does not return any result.

TKT_FLD_CUSTOM	Custom field	R

Example

string strTime = GetTimeStr(1); // Include seconds
string strGross = FormatGrossWt(1);

CTktFlds flds;
flds.Set(TKT_FLD_TIME, strTime);
flds.Set(TKT_FLD_GROSS, strGross);
flds.PrintTkt(TKT_STD);
