But I am creating Library ('Wind32 Static Library') using that code, so i can't write implementation of class in .h file.
So what should i do?

Look at what Microsoft has done for their template classes. They do have plenty of them. For eg: CArray, CPtrArray etc.

Can you post some source code showing how are you going with the creation of the tree control etc....

Somethings seem HARD to do, until we know how to do them.

pst files us a variant on the Jet database engine. You need to research the file structure and impliment the code to read it if you want to work with them. You really didn't expect it to be a bunch of plain text, did you ?

LOL - I can tell you from personal experience ( outlook died for me earlier this week ) the web is full of people willing to sell you a program that will recover your PST. The sample versions all show you your mail but do not recover it, but I found ones as cheap as $50, which worked really quite well.

CDialogs in staticly-linked .libs?

mdave14-Sep-06 18:34

14-Sep-06 18:34

I'm trying to move several CDialog-based classes to a common .lib file that will be statically linked.

I understand all the hoo-hah about resource handles when you're doing this with .dll's, but is there some magic dance I have to do to get dialogs to work when they're defined in a .lib?

My main program links to the lib just fine, but CDialog::DoModal() exits here:

if (lpDialogTemplate == NULL)
return -1;

What's more, when I open my executable file as resources in VS, the lib dialogs do not show up.

I know for a stone cold fact that this can be done, because I can statically link to external commercial libs like Stingray and get their dialogs to pop up. But I have studied that source code in vain for any clue as to why theirs works and mine doesn't.

Any suggestions?

how did u call the domodal of a dialog in the lib? I think this will be the issue of the resources handle.

overide the DoModal function in a derived class of the CDialog. And call

AFX_MANAGE_STATE(AfxGetStaticModuleState( )); and then call the base class' DoModal.

int MyDlg::DoModal()
{
AFX_MANAGE_STATE(AfxGetStaticModuleState( ));
return CDialog::DoModal();
}

That causes CDialog::DoModal to fail here:

HINSTANCE hInst = AfxGetResourceHandle();

because of an ASSERT:

_AFXWIN_INLINE HINSTANCE AFXAPI AfxGetResourceHandle()
{ ASSERT(afxCurrentResourceHandle != NULL);

And the CDialog resource is STILL not being linked into the executable. If I make a program that uses a statically-linked Stingray library and I open the executable as resources in VC, I can see the Stingray dialogs, whereas in my program, I cannot see the resources (and I even made sure that resource IDs were not duplicated in the lib and the main program).

I think this is the key issue here, the resources are simply not being linked into the executable for some reason.

Precompiled headers?

Hello everyone!
Here I am, stuck one more time... Frown | :(

Anyways, someone here told me a while ago that I should use stdafx.h on VC++ and something else on other compilers... What I'm doing rightg now is having this at the top of all my .H files:

#pragma once<br />
<br />
#ifndef _MSC_VER<br />
// Other compilers<br />
#include "Includes.h"<br />
#endif

And this at the top of my .CPP files:

#ifdef _MSC_VER<br />
// VC++<br />
#include "stdafx.h"<br />
#endif

What am I doing wrong? I get the following error 7 times (coincidentially, the same number of CPP files Wink | ;)

C:\Program Files\Microsoft Visual Studio 8\VC\include\xmemory(145) : error C2856: #pragma hdrstop cannot be inside an #if block

Thanks!

PS: If you can help me, I'll give you a cookie! Big Grin | :-D

The idea I beleive was just that you could use stdafx as a way to get your includes type behaviour down. If you're writing code for non MS compilers as well, you shouldn't use stdafx, because you can reproduce the behaviour without having that nasty #ifdef ( nasty in the sense that you're making work for yourself, you can't rely on the stdafx, so why use it at all ? )
