I'm updating an old (32bit) command line C++ program that I used to detect specific human input devices connected to the USB port.
the includes for this project are:
extern "C"
{
#include "hidsdi.h"
#include "hidusage.h"
#include "hidpi.h"
}
the project compiles without linking error as a 32bit application.
However, as soon as I switch to 64bit I get linker errors such as:
Error 1 error LNK2019: unresolved external symbol HidD_FreePreparsedData referenced in function "public: __cdecl DgCpDfuFunctions::~DgCpDfuFunctions(void)" (??1DgCpDfuFunctions@@QEAA@XZ) DgCpDfuFunctions.obj
Error 2 error LNK2019: unresolved external symbol __imp_SetupDiDestroyDeviceInfoList referenced in function "private: int __cdecl DgCpDfuFunctions::FindControlPanel(struct _hidDeviceStruct *)" (?FindControlPanel@DgCpDfuFunctions@@AEAAHPEAU_hidDeviceStruct@@@Z) DgCpDfuFunctions.obj
Error 3 error LNK2019: unresolved external symbol __imp_SetupDiGetDeviceInterfaceDetailA referenced in function "private: int __cdecl DgCpDfuFunctions::FindControlPanel(struct _hidDeviceStruct *)" (?FindControlPanel@DgCpDfuFunctions@@AEAAHPEAU_hidDeviceStruct@@@Z) DgCpDfuFunctions.obj
Error 4 error LNK2019: unresolved external symbol __imp_SetupDiEnumDeviceInterfaces referenced in function "private: int __cdecl DgCpDfuFunctions::FindControlPanel(struct _hidDeviceStruct *)" (?FindControlPanel@DgCpDfuFunctions@@AEAAHPEAU_hidDeviceStruct@@@Z) DgCpDfuFunctions.obj
I made sure that the 64bit "project properties" -> "Linker" -> "Input" are set up exactly like the 32bit project.
Note: I'm using the libraries from the Windows DDK, i.e. \lib\wxp\i386\hid.lib
EDIT: I'm using Visual Studio 2005

I am not sure about the problem but it seems that you are linking with 32-bit version of the library. Do you have a folder with x64 or IA64 in the lib folder.

I tried the IA64 folder... but then I see this error:
hid.lib(HID.DLL) : fatal error LNK1112: module machine type 'IA64' conflicts with target machine type 'x64'
NOTE:
this is my x64 debug configuration (preprocessor)
_DEBUG
WIN64
_CONSOLE
WINVER=0x0501
_CRT_SECURE_NO_WARNINGS
_CRT_SECURE_NO_DEPRECATE

IA64 is Itanium. x64 is AMD64 (and EM64T - Intel's implementation of AMD64).
The target market for Itanium is tiny because Itanium was a colossal failure. If you use a processor like an Athlon, Opteron, Xeon, Core 2, Core i7 and so on, it will be using x64 (AMD64/EM64T). If you buy 64bit Windows (such as XP 64 bit or Vista 64 bit) it will be x64.
You can't use IA64 on an x64 platform, so you need the x64 (probably labelled AMD64) versions of these libs, not the IA64 ones, which is exactly what the first error says.
I can't find these either (I only have x86 no matter what I try to install) so if you find/have found these 2 libs, please let me know 
Never mind, found it.

Most probably you might be debugging in release version. Since release version don't have debug informations by default, you can't debug it.
So options are
1) Debug in debug version.
2) Enable debug information in release version. For that take project settings and
a) Set C/C++ > Optimization as "disabled"
b) Set C/C++ > Debug Info as "Program Database"
c) Enable Link > Generate Debug Info.
Regards,
Jijo.

Debugging a shell extension is different then debugging other applications. For shell extensions you have to debug explorer.exe since it loads the shell extension. You cannot debug explorer.exe at the source level since it is part of OS and its source code is not available.
To get debugging symbols use symbol server to get the symbols for system binaries. You can read more about symbol server at here[^].
To configure symbol server in VS 2008 follow these steps:
1. Tools->Options->Debugging->Symbols
2. Under symbol files(.pdb) locations add an entry containing http://msdl.microsoft.com/download/symbols.
3. In cache symbols from ... give a path to save the symbols locally.
Also you will find lots of information if you google "debugging shell extensions".

I am getting an windows exception
001B:7C16E14F Ordinal1028+7D
Anybody help me to understand what is Ordinal 1028?????????

Using the debugger, you should be able to see what DLL is mapped into the address space shown in the exception and/or call stack.
Use a tool like DUMPBIN dump the exports from that DLL and you will be able to find out what exported function is causing the problem.
Note sure that will help you much, though...
Peace!

Ok, what does your code look like so far?

CComboBox::GetLBText
int GetLBText( int nIndex, LPTSTR lpszText ) const;
void GetLBText( int nIndex, CString& rString ) const;
Gets a string from the list box of a combo box. The second form of this member function fills a CString object with the item’s text.

Hi,
I want to learn DX10 and C++, I know C#, Java etc.
So I also know VS2008 EXPRESS as IDE for C#. But is it as good for C++ as well?
I'd like to know what you think, which IDE is best for developing with C++ and why?
Thx
|

|

as I already said some days ago, real programmers use vi. but it's up to you to use Visual Studio if you feel better with it 
personnaly, I only code C++/MFC, and yes, i code within VS.

Your kidding right? The editor is VC (Visual C++); an earlier version was Visual C/C++, also call VC. Before that there was the C only environment. The other languages, like C#, where added over time.
So the answer is yes.
error1408 wrote: which IDE is best for developing with C++ and why?
I always end up, eventually, using VC for C/C++. It's what I know best. If you are just learning C++ then you should stick to the IDE you are already use to, because in will reduce the learning curve.
Here are some C++ sites:

Good Luck!
