Converting AnsiString to Int

[bitshifter05]

Using Borland builder when I try to use an edit box as in input for an integer it says that you can't convert an ansistring to an integer. How do I get integers from the user.

Thanks

Use the function atoi [sig]<p>hnd<br><a href=mailto:hasso55@yahoo.com>hasso55@yahoo.com</a><br><a href= > </a><br> [/sig]

hnd's solution may work but I believe that AnsiString may need it's own method to convert. What you will need to do is accept a AnsiString input from the user, then convert the answer to an integer. This is what hnd suggested. I think that you may need to use StrToInt. This should correctly convert Borland's AnsiString to integer. One suggestion is to put this into a try ... catch statement in case the user inputs something that cannot be converted to an integer.

Ok ffat there are two ways:


String str;
int value;
str=EditBox->Text;
1. value=atoi(str.c_str());
2. Value=StrToInt(str);

But they are equivalent.
I personally prefer the first way. Probably because i come from a UNIX/C environment about 15 years ago and there were no String variables but characters.

hnd,

[tab]I wasn't certain since AnsiString is Borland's Pascal String implimentation. I was afraid that the standard C++ atoi wouldn't work with it. I do know that I have to use c_str() to go from AnsiString to string. Thanks for the tip, though.
