Familiar with AnsiString??

sorry i'm posting alot but you people are smart...

anywayz..


i've got an array:

AnsiString title[50];

and i eventually add values to the different indexs of the array.

for example

title[0] = "Bob";
title[1] = "Joe";
title[3] = "Skip";

now i don't fill up the last 46 slots or so...

when i goto do a while loop for saving data to a file it does a forever loop causing my program to loop constantly.(which obviously isn't good)

x = 0;
while (title[x] != Null)
{
file << title[x];
x = x + 1;
}

I've done a little reading and testing but i can't quite figure out the problem. I'm thinking that AnsiStrings that are empty aren't Null. And thats my problem i don't know what they are..Wouldn't title[x].c_str(); add null to end? or something i really don't know i'm lost.. :)

ive tried:

x = 0;
while (title[x] != "")
{
file << title[x].c_str();
x = x + 1;
}

and

x = 0;
while (title[x] != " ")
{
file << title[x].c_str();
x = x + 1;
}

and

x = 0;
while (title[x].c_str() != Null)
{
file << title[x].c_str();
x = x + 1;
}

but always a forever loop. I've noticed NullStr(); function which i think i may need but i can't figure out how to use it.. the

file << title[x].c_str();

part works so my only problem is the while loop. Any help would be greatly appreciated

I assume you use Builder.

A solution is a collection called TStringList:

Code:

---

TStringList *stringlist = new TStringList();
stringlist->Add("1");
stringlist->Add("2");
stringlist->Add("3");
stringlist->Add("4");
for(int n = 0; n < stringlist->Count; n++)
{
    Application->MessageBox(stringlist->Strings[n].c_str(), "", MB_OK);
}
delete stringlist;

---

Also, you don't need to worry about the size of the StringList, as u have to do with an array.

A couple other solutions would be:

look up the AnsiString class to see if it has a member function looking for empty strings, like isEmpty() or empty().

initialize all strings in the array to a given value using a loop. compare each string to the default. If current string is not default value, then do whatever. I believe that "" or "\0" will create an empty string if AnsiStrings are not "empty" by default.

keep an index/counter variable equal to last index used in the array, or number of strings in the array, and use that to stop loop.

cool....thnx for both those i'll try em both out......
