Concactinating Strings

[Jaffob]

My code has a semicolon . When I copied it in I must have accidentially removed it.

If there was no semicolon, the code itself would not compile.

I know that, just pointing it out

EXPRESSION(
	/* ID */			0,
	/* Name */			"Name(",
	/* Flags */			EXPFLAG_STRING,
	/* Params */		(1,EXPPARAM_STRING,"Parameter")
) {
	char * str1 = (char *)"1st String";
	char * str2 = (char *)ExParam(TYPE_STRING);
	char * str3 = rdPtr->rRd->GetStringSpace(strlen(str1) + strlen(str2) + 1);
	strcpy(str3, str1);
	strcat(str3, str2);
	ReturnString(str3);
}

Raw strings in C are a pain...
But you could also use C++ CStrings like this:

EXPRESSION(
	/* ID */			0,
	/* Name */			"Name(",
	/* Flags */			EXPFLAG_STRING,
	/* Params */		(1,EXPPARAM_STRING,"Parameter")
) {
	CString str1 = "1st String";
	CString str2 = (char *)ExParam(TYPE_STRING);
	CString str3 = str1 + str2;
	ReturnStringSafe(str3.c_str());
}

With Dynasoft's code my extension does not compile. It seems like CString has not been included. How can I include it?

[Dynasoft]

Can you tell I haven't used them for a while :P
I got CString (a microsoft specific thing) and string (the C++ standard one) confused. Replace all the CString in my code with string, and add:

#include <string>

EDIT: So this:
EDIT: No + operator, only += apparently, so change like this:
EDIT3: Scratch that last edit

#include <string>

EXPRESSION(
	/* ID */			0,
	/* Name */			"Name(",
	/* Flags */			EXPFLAG_STRING,
	/* Params */		(1,EXPPARAM_STRING,"Parameter")
) {
	string str1 = "1st String";
	string str2 = (char *)ExParam(TYPE_STRING);
	string str3 = str1 + str2;
	ReturnStringSafe(str3.c_str());
}

There is a + operator for std::string.

It wasn't listed in the online c++ help I looked at.
EDIT: Changed my post back.

Thanks everyone (Especially Dynasoft for his code)! It works now.
