I had to go back and read your original post to figure out what you're
asking... You want to 'insert "Type" into a field to display it'.
1. Open your database.
2. Use DmQueryRecord (or similar method) to get a handle to a record.
3. Lock the handle to get a pointer to the record and typecast that
pointer to ModuleType.
3. Then you have 3 pieces of data:
yourPointer->day - a number, 0 thru 6
yourPointer->errands - a string
yourPointer->Type - an enum (stored as some kind of integer)
4. Display the above three in one or more fields on a form
a) convert the data to a string (here you may use the method I
previously gave)
b) call a function to put that string in a field
Here are two functions that will help with the general case of putting
a string in a field:
// Set text in a field, given a fieldID and a handle to the text
static FieldPtr SetFieldTextFromHandle( UInt16 fieldID, MemHandle txtH
)
{
MemHandle oldTxtH;
FieldPtr fldP;
FormPtr frmP = FrmGetActiveForm();
// get the field and a handle to its text
fldP = FrmGetObjectPtr( frmP, FrmGetObjectIndex( frmP, fieldID ) );
ErrNonFatalDisplayIf( !fldP, "missing field" );
oldTxtH = FldGetTextHandle( fldP );
// set field to new text
FldSetTextHandle( fldP, txtH );
FldDrawField( fldP );
// free old MemHandle
if ( oldTxtH ) MemHandleFree( oldTxtH );
return fldP;
}
// Sets text in a field, given a fieldID and a pointer to a string
static FieldPtr SetFieldTextFromStr( UInt16 fieldID, Char *strP )
{
MemHandle txtH;
txtH = MemHandleNew( StrLen( strP ) + 1 );
if ( !txtH )
return NULL;
StrCopy( MemHandleLock( txtH ), strP );
MemHandleUnlock( txtH );
return SetFieldTextFromHandle( fieldID, txtH );
}
