question about the AppWizard

Forums: 

Dear everyone
I can create a occfram window by ocaf Appwizard in MS
vc++ 6.0.I want the window to work as that when I click a button ,a line or circle will be painted.So I used the code of the sample"AISBasic".Here is the code:
gp_Lin L(gp_Pnt(0.,0.,0.),gp_Dir(1.,0.,0.));
Handle(Geom_Line) aLine = new Geom_Line(L);
Handle(AIS_Line) anAISLine = new AIS_Line(aLine);
myAISContext->Display(anAISLine);
But unfortunatly many errors come:
E:\yier\sixth\MainFrm.cpp(91) : error C2065: 'gp_Lin' : undeclared identifier
E:\yier\sixth\MainFrm.cpp(91) : error C2146: syntax error : missing ';' before identifier 'L'

Could Someone do me a favor,and tell me how to use the Appwizard?Right now I am so confused, I will so appreciate your help...

Sharjith Naramparambath's picture

The solution is simple; for every class name you see in the error message, simply include the header for that. eg.
E:\yier\sixth\MainFrm.cpp(91) : error C2065: 'gp_Pnt' : undeclared identifier
for this write #include in your .cpp file

You probably copied only the code from the sample. Also include the headers and it will compile!

Also from the messages I see above, it seems that you have not added the code in a suitable place. The Application Document source file is the suitable place to add the geometry creation to keep the project organized and consistent.

You also require some knowledge of the MFC Document/View architecture that the wizard generated code uses.

Hope my suggestion helps you!

Dear Nair Sharjith
Thank you very much.
According the sample ,I added the include file one by one and then the errors disappeared.
Thanks a lot.

dear friends;
i would like to create a new workspace in Microsoft Studio 2005 (application console win32), and i like to compile my code with opencascade librairy 6.2:
for exemple:
#include
error: when i compile my code: not open math_matrix.h: not such file or directory
please help me.

Sharjith Naramparambath's picture

Hi,
Go to the project options and set (add) the directories for include, lib and bin respectively to the corresponding Opencascade directories.

Regards
N, Sharjith

HICHEM's picture

hi,
firestly think you for your reply, secondly, i want to project options and i set (add) the directories for include (D:ros/inc and D: ros/win32;)
i compile my code: error: "Wrong compiler options has been detected. Add /DWNT option for proper compilation!!!!!"

please help me; i'm sorry for my english
think you

Sharjith Naramparambath's picture

Hi,
If the path you have written is exactly the same shown above, the mistake is the missing slash after D:
Have you installed OpenCASCADE into D: directly?

Also add the /DWNT as the compiler suggests. It is a macro required by OpenCASCADE. Either set it at the compiler options by passing /DWNT or by adding..

#ifndef WNT
#define WNT
#endif

in your stdafx.h file

Regards
N. Sharjith

think you for reply:

after add the : #ifndef WNT
#define WNT
#endif

to stdafx.h , i compile my code many error:(please help me)

Hi,
This is the link error which is due to improper setting of the lib directory in the project settings page. There is a combo box which shows include, bin, library, source etc. You have to set the diectory to ros/win32/lib. For the generated code to have all declarations and preprocessor directives the best way to get rid of all errors is create a project with the VC6 appwizard (it does all the necessary settings for you) and convert the project into VS2005 by loading into it. This is what I do.

Hope this helps

Regards
N. Sharjith

hi;
would you help me to solve the erreur link2001;

Handle(TColStd_HSequenceOfTransient) myList1 = myStepReader.GiveList("step-faces");

nstepFaces = myList1->Length();
nbreTransFaces = myStepReader.TransferList(myList1);
cout TopoDS_Shape shape = myStepReader.OneShape();

error when i compile my code/
