I am struggling with the PhoneNumberLookup function. I have a test
application that takes a string and updates a field on a form. Then I call
the PhoneNumberLookup function with that field. All that works fine.
However, when the PhoneNumberLookup function returns the address I select, I
receive a "MemoryMgr.c, Line:5253, Chunk under-locked" error. I've reviewed
all the books I have on Palm computing and looked at the MemoPad SDK which
also uses the PhoneNumberLookup function and I can't find the answer.
Following is a snippet of the code I'm using. As you'll notice I'm not
doing anything with the returned field currently. Eventually, when I get
this working, I'm going to copy the information in the field to a string
(HiddenHiddenField is declared with a maximum length of 160):
FormPtr hiddenfrmP;
FieldPtr fieldP;
MemHandle textH;
Char* str;
// initialize "hidden" form and retrieve "hidden" field
hiddenfrmP = FrmInitForm (HiddenForm);
FrmDrawForm(hiddenfrmP);
fieldP = (FieldPtr)FrmGetObjectPtr(hiddenfrmP,
FrmGetObjectIndex(hiddenfrmP, HiddenHiddenField));
textH = FldGetTextHandle(fieldP);
textH = MemHandleNew ( 5 );
str = MemHandleLock(textH);
StrCopy(str, "Test");
MemHandleUnlock(textH);
FldSetTextHandle(fieldP, textH);
FldDrawField(fieldP);
MemHandleFree(textH);
// perform lookup
textH = FldGetTextHandle(fieldP);
textH = MemHandleNew ( 161 );
PhoneNumberLookup(fieldP);
FldSetTextHandle(fieldP, textH);
FldDrawField(fieldP);
// free handle to prevent memory leak
StrIToA(result1P, FldGetTextLength(fieldP));
MemHandleFree(textH);
FrmDeleteForm(hiddenfrmP);
Thanks,
Dave
