As the error says:
unable to open include file 'ieview.hpp"
unable to open include file 'imageenview.hpp"

Do you have those two .hpp files?

[kaisin]

i ran a search on windows but i cant find the files. to which folder, do i put the files in?

[Mitsakos]

If you have the files you must put them in the same directory like your .cpp file.

error messages
ee2209 unable ot open include file hyieutils.hpp
e2090 qualifier hyieutils is not a class or namespace name
e2040 declaration terminated incorrectly

lines that cause the errors are in bold.
can anyone guide me?
i have placed all the .hpp files of the imageen into c:\progra~1\borland\project\project_name

did i place them wrongly?

[Mitsakos]

OK,
you must understand the #include syntax.
When you have "< >" that means that the compiler will look, for the header file, only at the directory of the default header files.
When you have double quotes (" ") then the compiler will first look at the folder where your .cpp file is and then at the default directory.

So, if #include <hyieutils.hpp> is a file you have in your programs directory change it to #include "hyieutils.hpp"

Hope this helps

(Please use [code][/code] tags... The # button at the right...)

[kaisin]

Thanks for all the replies. Problem is solved. However i got this error

"Unable to invoke code completion due to errors in source code"

when i tried to installed a 3rd party package --ImageEn


Before adding anything, the program runs well, However i tried to add the code

ImageEnView1->

thats when the error arises.
can anyone help?

code as follows:


//--------------------------------------------------------------------------
#include <vcl.h>
#pragma hdrstop
#include <dir.h>
#include <math.h>


#include "Unit1.h"
//---------------------------------------------------------------------------
#pragma package(smart_init)
#pragma link "WMPLib_OCX"
#pragma link "imageenview"
#pragma link "imageenproc"
#pragma link "histogrambox"

#pragma resource "*.dfm"
TForm1 *Form1;
//---------------------------------------------------------------------------
__fastcall TForm1::TForm1(TComponent* Owner)
: TForm(Owner)
{
}
//---------------------------------------------------------------------------

void __fastcall TForm1::DriveComboBox1Change(TObject *Sender)
{

}

{

Button1->Default = true;
FilterComboBox1->Filter = "All files (*.*)|*.*| Video files (*.mpg;*.avi)|*.mpg;*.avi";



Button1->Default = true;

}

ImageEnView1->

[Mitsakos]

I have no idea what all those are but ImageEnView1-> doesn't mean anything.
I suppose ImageEnView1 is a pointer to a class object.
The "->" notation is used to access the members of a class through a pointer.
So, after "->" you must have a member of the ImageEnView class. It is illegal to have it like that...
