Thanks.
I gave it a try. Still no success.
The following is my attempt to call your function from a menu
(with a few artifacts from a prior attempt to call :
SetFieldTextFromStr(field, pText, redraw)).
This doesn't save anything, it is merely a placeholder for what I eventually
hope to do, which also
requires putting the text to the screen:
case Save:
{
FormType * frmP;
Char* pText = (Char*) MemPtrNew(5); // allocate 5 bytes
FieldType * field;
Boolean redraw;
struct transformer
{
UInt16 TranskVA;
} My_Transformer;
redraw=true;
/* Clear the menu status from the display */
MenuEraseStatus(0);
frmP = FrmInitForm (TransformerForm);
field = GetObjectPtr(FrmGetObjectIndex(frmP, kVA));
// copy kVA into the char ptr
StrCopy(pText, "2000");
//Actions taken due to selection of transformer "save"
//SetFieldTextFromStr(field, pText, redraw);
mySetFieldText(frmP, kVA, pText);
//mySetFieldText(FormType *frmP, UInt16 fieldID, Char *st)
//Actions that follow if nothing is done by code
//to save data
/* Display the Transformer Box. */
FrmDoDialog (frmP);
FrmDeleteForm (frmP);
handled = true;
break;
}
My current resource header file looks like:
/* pilrc generated file. Do not edit!*/
#define TransAbout 1021
#define Save 1020
#define kVA 1019
#define XFMROKButton 1018
#define DataEntryMenu 1017
#define TransformerForm 1016
#define AboutVersionField 1015
#define AboutOKButton 1012
#define AboutForm 1011
#define MainClearTextButton 1010
#define MainDescriptionField 1009
#define MainForm 1008
#define RomIncompatibleAlert 1007
#define EditOnlyMenuBar 1005
#define OptionsAboutPSEDAT 1004
#define PD1_XFMR 1003
#define MainMenuBar 1001
(just for anyone doubting the field name)
