Iam getting the following error [C++ Error] main.h(60): E2303 Type name expected at the point of the ** what do I need to do ? Help any one !

 

[trollacious]

Since you're inside the class, you don't need the support0:: for scope resolution.

Lee

 

[WayneStev]

OK I removed the referance to support0:: I STILL get the error.

 

[trollacious]

Where are the data types of the variables in the parameter list? You have them in the prototype, but not in the actual function.

Lee

 

[WayneStev]

OK I will try that an other words I need to type the varables in the parameter list in the method (function in the class. I am getting ready to shut down for this week BUT I WILL TRY YOUR SUGGESTION FIRST THING MONDAY I will let you know how it goes

 

[WayneStev]

I added data types like you suggested. This STILL DID NOT change eoany thing . I am STILL getting the error ???

 

[trollacious]

Show your new code. Can't help you with what I don't see.

The above is the current code related to the erroe note line of error. **

 

[Prattaratt]

Maybe you should try void ** instead of ** void???

The simplest solution is the best!

 

[WayneStev]

OK I can see whare YOU made the error. I sorry but the (**) is NOT part of the code but whare or tbe line the error seems to take place.

 

[Prattaratt]

Did you happen to notice that your #includes are inside of the #ifdef block, but your class definition and FileInfo struct definition are outside of it? Therefore, String, FILE, fopen, fprint and fclose may or may not be defined at that point.
Also when writing your implementation of the class member, you should either write it in the corresponding .cpp file or inline in the class declaration as follows:

// filename Main.h 

#ifndef mainH
#define mainH

...

class support0 {

public:
        virtual void PutFileAndHashInfo(String s0, long int s1);
};

#endif

//  filename main.cpp

#include "main.h"
#include<stdio.h>

void support0::PutFileAndHashInfo(String s0,long int s1) {
 //TODO: Add your source code here
FILE *Info;
String FName ="hasinfo.ess";
    Info = fopen(FName,"a");
    fprintf(Info,"%s/n%i",s0,s1);
    fclose(Info);
}

if you're using C++ Builder you're still going to recieve compile errors regarding the String Fname line and a conflict with VCL's AnsiString; still working on those problems.

The simplest solution is the best!

I am also faced the same erro and thought tocreate the component by reading the eveloper's guide. u please read the developer guide and implement the sample code...

This mayworks fine for you..
