Band Object Implementation Sample

Hello,
well, Let me start saying that I know nothing about MSVC++.

What I want to do is just compile a pretty cool sample that is it this URL:
http://msdn.microsoft.com/isapi/msdnlib.idc?theURL=/library/psdk/shellcc/shell/samples/bands/bandobjs_cpp.htm

All files are there, what I have to do know...
I tried to create a new project and place all files there but I received an error message:
"Compiling...
StdAfx.cpp

Can somebody help?

thanks

Simply add a

#include <stdafx.h>

at the beginning of every file mentioned above, and it should work.

Feel free to ask if you encounter problems!

To elaborate: VC++ builds so called 'precompiled header files', in which it stores (as the name implys) information about header files invoked in your project in order to speed up the build process. This is done through one specific header (namely 'stdafx.h') - if it is missing in your .cpp file, VC++ is insulted ;-)

The name of the dll should be "bandObjs.dll", but I changed to explorer.dll, Could it be the problem??

thanks

jkr

Hmm, did you set up a new project for this task? If not, make sure to either do so or remove the 'explorer.cpp' file from your project...

ASKER

He jkr, can you help me?

I have all files, *.cpp and *.h and I have MSC++ 6.0

I am create a new project, click in Project tab, my project name will be bandObj, location = "c:\c++\bandObjPR

In the wizard I choose "A simple DLL project" then I click finish and after OK button ...

Now I have to add my files, right?
SO I click Project/Add to Project/Files
and add all files that I have...

Now I click in build/build bandObj.dll

and I got that message:
"--------------------Configuration: bandObj - Win32 Debug--------------------

What am I doing wrong?

Ok I found the error...

Hey, did you ever try to create a new explorer bar, like search bar, in IE5?
it's pretty cool!!

jkr

Sorry for the delay, have been 'offline' for a moment ;-)

No, I haven't ... but perhaps I'll give it a try when my time allows it :-(

dorock

ASKER

I have to learn alot of c++ to do it...
:(
Should have a way to do it using VB :)

have a good night..

see ya

I had a problem when I compiled it and tryed to register the component I received that error
"bandobj.dll was loaded, but the DllRegisterServer entry point was not found.
DllRegisterServer may not be exported, or a corrupt version of bandobj.dll may be in memory. Consider using PView to detect and remove it"

Do you know how to solve it?

thanks...

jkr

Hmm, I assume you didn't use a .def file...

It has to be something like

;mydll.def : Declares the module parameters for the DLL.

LIBRARY MYDLL
DESCRIPTION 'blah'

EXPORTS
DllCanUnloadNow @2 PRIVATE ;DLL unloading
DllGetClassObject @3 PRIVATE ;Component object model
DllRegisterServer @4 PRIVATE ;Component object model
DllUnregisterServer @5 PRIVATE ;Component object model

Just adding it to your project should be sufficiant...

ASKER

YESSSSSSSSS!!!
It worked!!!

thanks alot man!!!

I just needed to took of the last line
"LIBRARY bandObj.dll
DESCRIPTION 'blah'

EXPORTS
DllCanUnloadNow @2 PRIVATE ;DLL unloading
DllGetClassObject @3 PRIVATE ;Component object model
DllRegisterServer @4 PRIVATE ;Component object model
"

thank you!!!

have a good day!
