Hi All,
I have a form with 2 fields with max limit of 15 chars. User enters the data
and I send those data to our system. It sounds so simple. But whenever I use
Field related functions and run the Gremlin, it crashes saying “Memory
Leak”. I am using the latest POSE (4.1).However, if I comment out those
functions and run the Gremlin, no Memory leaks. I went through newsgroup
archives, documentation etc and I think I am following all the steps needed to
grab the info from the field. I have enclosed part of my code which is causing
the problem below. If anyone is interested, I’ll post part of the Memory leak
Gremlin events. Any clues as to where I am going wrong???
static MemHandle txtNameH, txtPasswdH;
MemPtr namePtr = NULL, passwdPtr = NULL;
Word fldIndex;
char usrNameStr[20], passwordStr[20];
//If Send button is clicked, send the command to the system
//and display the response to the user.
case SystemLoginSendButton:
MemSet(usrNameStr, sizeof(usrNameStr), 0);
MemSet(passwordStr, sizeof(passwordStr), 0);
usrNameFld = GetObjectPt(SystemLoginUsrNameField);
ErrNonFatalDisplayIf(!usrNameFld,"Missing Field");
unameLen_u16 = FldGetTextLength(usrNameFld);
passwdFld = GetObjectPtr(SystemLoginPasswordField);
ErrNonFatalDisplayIf(!passwdFld,"Missing Field");
passwdLen_u16 = FldGetTextLength(passwdFld);
// if the username or password field is valid
if (( usrNameFld != NULL ) && ( passwdFld != NULL )) {
txtNameH = FldGetTextHandle(usrNameFld);
if(txtNameH) {
FldSetTextHandle(usrNameFld, NULL);
namePtr = MemHandleLock(txtNameH);
}
txtPasswdH = FldGetTextHandle(passwdFld);
if ( txtPasswdH ) {
FldSetTextHandle(passwdFld, NULL);
passwdPtr = MemHandleLock(txtPasswdH);
}
if (( (unameLen_u16 > 0) && namePtr ) && (
(passwdLen_u16 > 0) && passwdPtr )) {
//make sure you NULL terminate the usrNameStr string appropriately
StrNCopy(usrNameStr, namePtr, (sizeof(usrNameStr) - 1));
StrCat(usrNameStr, "\r");
usrNameStr[sizeof(usrNameStr) - 1] = NULL;
if(txtNameH) {
err = MemHandleUnlock(txtNameH);
ErrFatalDisplayIf(err, "Could not Unlock chunk in name field.");
//FldSetTextHandle(usrNameFld, txtNameH );
}
//make sure you NULL terminate the Password string appropriately
StrNCopy(passwordStr, passwdPtr, (sizeof(passwordStr) - 1));
StrCat(passwordStr, "\r");
passwordStr[sizeof(passwordStr) - 1] = NULL;
if(txtPasswdH) {
err = MemHandleUnlock(txtPasswdH);
ErrFatalDisplayIf(err, "Could not Unlock chunk in password field.");
}
Thanks a lot for your patience.
