Char Strings []

[Chris_SE]

Is there a way to make char strings(arrays I guess) dynamic? I need to be able to resize and redefine the value. Unfortunately none of the string headers Ive found use chars

download:
http://lvp.com/data/cpluspc/string.cpp
http://lvp.com/data/cpluspc/string.h
http://lvp.com/data/cpluspc/bool.cpp
http://lvp.com/data/cpluspc/bool.h

bool.h is required for string.h...

to use these headers just do:

String test; //notice the capitalization
test = "hello";
int l = test.length(); // length function
cout << test.substr(0, l); //sub string function
cout << test.find("h");  //find function

the find function is overloaded, so you can have a character argument, or a string argument.

If you are using MFC you can use the CString class.

CString strTemp;
strTemp = "HI";

Dennis(Benji ) what was the platform sdk you were talking about earlier?

[parksie]

Don't use CString - it has a reallocation bug

Use the STL string class <string> (make sure to have using namespace std; in there!)

The platform SDK is the greatest source of documentation in the world. It's at msdn.microsoft.com - choose "Downloads".

Didnt they fix that in SP3???

[Chris_SE]

Parksie is it actually called "platform sdk"?

Chris:

Here is a link to download the Platform SDK

It's called the Platform SDK because it's information for developing apps for the Windows platform. It's the same meaning as in the phrase 'platform-independant'. SDK stands for software development kit (I think).

I think so, but it's just in case he doesn't have SP3

Oh...for those using the STL classes and want to use Unicode, then this code snippet might help:

#ifdef UNICODE
typedef String wstring;
#else
typedef String string;
#endif

Both string and wstring are template implementations of the basic_string class. string uses the char type, and wstring uses the wchar_t type. Alternatively, you may wish to use:

typedef String basic_string<TCHAR>;

Thanks

You can also use the following to declare a string:

char* MyString;

Er...Megatron...he wanted a dynamic string. (I see what you mean, but probably one where you didn't have to bother reallocating it yourself)
