A missing or incorrect header file would yield a preprocessor/compiler error, not a linker error.

Hi ,
I developing an application that hooks the Open/Save dialog for getting the selected file path. currently am able to hook the common dialog but it's not working on office Open/Save dialog. On Searching i found that Office is using separate Open/Save dialog. Can anyone help me to identify the Office Open/Save dialog messages equivalent that of common dialog's
CDN_FILEOK
CDN_INITDONE
CDM_GETFILEPATH
CDM_GETFOLDERIDLIST
CDM_GETFOLDERPATH
CDM_GETSPEC
CDM_HIDECONTROL
CDM_SETCONTROLTEXT
CDM_SETDEFEXT
?
thanks

Hi,
I guess I tried in the subject matter to explain the problem
let me say before I describle the problem that I am using a few of the same headers .h files in both The C and C++
project
In the begining when I was getting unresolved extern __declspec from the link trying to import C symbols
into my C++ project I thought it had something to do with were I specfied my LIB file (I am using VS 2005 )
Linker -> General then the specfic .Lib under Linker -> Additional inputs
Now however I getting the Idea that a part of this problem is that I have C++ project importing C symmbols
When I declare the imports as extern "C" __declspec(dllimport) in the C++ project I resolve a few of the externs
However I still get unresolved ___impl_func
seems __impl is added to C export but linking the C++ project it doesn't see these names
would doing the following when building the C exports in the C++ projects Help
#ifdef __cplusplus
DLL_EXPORT __cdecl telling the C++ compiler that this is C export
Maybe there is simeple soultion to all of this if you know any please Share
Thankx

How are the C items exported?

real vinalla statement __declspec(dllexport) int func(...,)
this probelm has to do with mixed language import/export C/C++
But then again I am sure they DLL's written in other Languages e.g. VB wich use C/C++ DLL's
so what I doing is not that uncommon
However part of the problem is that I am including the same Headers in both the C/C++
So ......
If have gotten rid of most of the errors with the exception of some unresolved externs with a prefix of __imp
Which I understand the compiler appends to a C export When the Link of C++ reads the .Lib
generated by the linker of the C proj it cann't seem to match __imp_func
maybee I need to qualify the C DLL EXPORT (___imp_func ) wih something like __cdecl to make it drop the __imp
prefix
Dont know ???
thankx

I think you can drop the ___imp_func specifier and use standard __declspec(dllexport).

the __imp is generated by the compiler for DLL EXPORTS on a C build
Linking the C++ projects with .lib from C gives me the problem

That's what you should be doing IMO. Then you only make changes in one place.
How are you handling the dllimport/dllexport difference depending on the type
of module being built...with a macro?
You should be able to form your shared header something like this:
#ifdef MY_DLL_BUILD
#define MY_IMPORTEXPORT __declspec(dllexport)
#else
#define MY_IMPORTEXPORT __declspec(dllimport)
#endif
#ifdef __cplusplus
extern "C" {
#endif
MY_IMPORTEXPORT void SomeFunction();
#ifdef __cplusplus
}
#endif
Note that's a simplified solution. You may need more for certain
types of builds.

According to MSDN, the default constructor for a GDI+ RectF class will initialize the X and Y members to zero. It doesn't say anything about the Width and Height members. Does anyone know if the Width and Height get set to zero? I did some quick testing and it appears so but I thought I'd ask around before relying on this possibility in case I was getting fooled somehow.
From MSDN:
******************************
RectF::RectF Constructor
Creates a RectF object and initializes the X and Y data members to zero. This is the default constructor.

|
|
|
|
Here's the source code...
RectF()
{
X = Y = Width = Height = 0.0f;
}

Where'd you find that?
Is that in the header?

Oops, by the way...thanks

Heh I just traced into it in the debugger....it was quicker
at the moment then a text search. And yes, it's in the header...
gdiplustypes.h. Looks like the entire class is inline methods.

Hi All,
I am looking some code in a dll which is part of a project I inherited & see the following code in a CWinThread derived class:
<br />
BOOL CMyThread::InitInstance()<br />
{<br />
AfxEnableControlContainer();<br />
AfxOleInit();<br />
<br />
CoInitialize(NULL);<br />
<br />
AFX_MANAGE_STATE(AfxGetStaticModuleState());<br />
<br />
return TRUE;<br />
}<br />
Is it me, or does AFX_MANAGE_STATE() not belong here? The thread is instantiated from other plaes in code where AFX_MANAGE_STATE has already been called & there is no cross-thread communication w/ other threads or the calling process.
Is it common practice to call AFX_MANAGE_STATE from a CWinThread derived class's InitInstance() ?
Also, does it matter if I call CoInitialize/CoInitializeEx before calls to AfxEnableControlContainer()/AfxOleInit()?
Thanks!

Only if the place in which it is called will be loading resources from the DLL.

Hmm.. so if the InitInstance brought up a CDialog based class & called DoModal(), it'd be loading resources & it'd be a good idea to call this?
such as:
<br />
viod MyDll_ShowScreen()<br />
{<br />
AFX_MANAGE_STATE(...);
...<br />
AfxBeginThread( RUNTIME_CLASS(CMyThread) );<br />
}<br />
<br />
CMyThread::InitInstance()<br />
{<br />
AFX_MANAGE_STATE(....);
<br />
CMyDlg dlg(...);<br />
dlg.DoModal();<br />
<br />
PostThreadMessage(WM_QUIT,0,0);<br />
return TRUE;<br />
}<br />
<br />
MyDll_ShowScreen();<br />
|

Yes, otherwise the InitInstance() method would be looking for CMyDlg's dialog template in the EXE that owns your DLL.

My understanding is that AFX_MANAGE_STATE is it's on more of a module level, not so much on a per-thread level.
