Hi, I am doing a program to append a string to the other one. but am getting a panic "Applicatoin closed".. My code is: HBufC* Buf = StringLoader::LoadLC(R_HEWB_COMMAND1_TEXT ); // loading // string from the resource. StrDisplay(Buf); // my own function to display a string // function to display a string. } Its working fine when i display a single string but gives a panic whenever i append a new string.. Plz help me in finding the error... thanx in advance.. |

I don't know the error, but you can try this code
// Concatenate a string
void AddStringL(HBufC8 **aStrOrg, const TDesC8 &aStrToAdd) {
if (!*aStrOrg) {
*aStrOrg = aStrToAdd.AllocL();
} else {
*aStrOrg = (*aStrOrg)->ReAllocL((*aStrOrg)->Des().Length() + aStrToAdd.Length());
(*aStrOrg)->Des().Append(aStrToAdd);
}
}
// Concatenate a string
void AddStringL(HBufC **aStrOrg, const TDesC &aStrToAdd) {
if (!*aStrOrg) {
*aStrOrg = aStrToAdd.AllocL();
} else {
*aStrOrg = (*aStrOrg)->ReAllocL((*aStrOrg)->Des().Length() + aStrToAdd.Length());
(*aStrOrg)->Des().Append(aStrToAdd);
}
}
// Concatenate a string
void AddStringL(HBufC8 **aStrOrg, const TDesC &aStrToAdd) {
if (!*aStrOrg) {
*aStrOrg = HBufC8::NewL(aStrToAdd.Length());
(*aStrOrg)->Des().Copy(aStrToAdd);
} else {
*aStrOrg = (*aStrOrg)->ReAllocL((*aStrOrg)->Des().Length() + aStrToAdd.Length());
(*aStrOrg)->Des().Append(aStrToAdd);
}
}
// Concatenate a string
void AddStringL(HBufC **aStrOrg, const TDesC8 &aStrToAdd) {
if (!*aStrOrg) {
*aStrOrg = HBufC::NewL(aStrToAdd.Length());
(*aStrOrg)->Des().Copy(aStrToAdd);
} else {
*aStrOrg = (*aStrOrg)->ReAllocL((*aStrOrg)->Des().Length() + aStrToAdd.Length());
HBufC *temp = HBufC::NewL(aStrToAdd.Length());
temp->Des().Copy(aStrToAdd);
(*aStrOrg)->Des().Append(*temp);
delete temp;
}
}

well, perhaps a Symbian fresher course is in order for you two.....
CleanupStack::PopAndDestroy( Buf );
_LIT(KNew, " New");
You just destroyed Buf above, yet you use it below!!!
TPtr Pointer = Buf->Des();
