The API is not bound to a compiler/IDE version or another. More important is the Platform SDK in this case.
The main issue can be that a newer compiler is usually much less forgiving with warnings and errors than a previous one. Visual C++ 2005 compiler was absolutely "devastating" compared to Visual C++ 6.0 - after the first rebuild I get maybe 50 times more warnings, and sometimes even errors.
For example, a code like
for(int i = 0; i < 1; i++) {
f(i);
}
for(i = 0; i < 1; i++) {
g(i);
}
works in Visual C++ 6.0, but if you compile in Visual C++ 2005 with "force conformance in for loop scope", the second for statement will complain about undeclared i variable.
But go for it, if you can dedicate time for getting rid of those pesky warnings; expect also some code reworking.

The real question is do you want to take advantage of .NET?
I personally don't care for the VS 2005 IDE, but the complier is worlds better than VC 6.0 Complier. If you use STL at all it’s worth the upgrade to VS2005 alone.
If you are just doing C++ Development you can use VS2005 without worrying about .NET. Should you decide to move devolvement from VS 6.0 to VS 2005 there where some very important changes made. VS 2005 targets version 8 of the C / MFC run time, this isn’t a huge issue except most computers do not have the updated version of the run time installed. The only way to update the run time versions is to install them. Gone are the days of dropping dependency DLLs of that nature onto the computer, the new paradigm is SAS (Side By Side) DLL Support. This allows many versions of the same DLL to be run on the same box, theoretically eliminating DLL Hell. Additionally, by default all projects are UNICODE now (not generally an issue but it did trip me up for a few minutes).
Good Luck!

Please can any one of you help me how to invoke dialogs from Reource-Only DLL in EXE.

I have one MFC application, I removed the resource(.rc file) in the "File View". I created a "Reource-Only DLL" and I added that removed resource(.rc file and resource.h file) here. With Linker option as /NOENTRY.
I have done one small test program and its working fine. But if I implement same in my application I'm getting Error code as 1407 (i.e., "Cannot find window class.") in my application workspace.
If i debug through I will get this error in "hWnd = ::CreateDialogIndirect(hInst, lpDialogTemplate,pParentWnd->GetSafeHwnd(), AfxDlgProc);" and file path is "..\MFC\SRC\DLGCORE.CPP"
Please can you help me on this...

Refer localization [^] section of this site.
You will get good idea , how to acheive this.

Try "AFX_MANAGE_STATE(AfxGetStaticModuleState());" before you call the dialog in the dll

Hi,
Even I tried with "AFX_MANAGE_STATE(AfxGetStaticModuleState());".

If is a MFC dll, make the project MFC extension dll, load the dll normally with LoadLibrary or AfxLoadLibrary, and use it directly.
For example, you may have a dialog implemented in DlgCustom.cpp/.h in DlgCustom.dll but resource is actually in DlgCustomRC.dll.
A possible implementation can be
#include "../DlgCustomRC/resource.h"
class CDlgCustom
{
enum IDD = { IDD_CUSTOM };
protected:
HMODULE m_hRC;
};
CDlgCustom::CDlgCustom()
{
m_hRC = LoadLibrary(_T("DlgCustomRC.dll"));
}
CDlgCustom::~CDlgCustom()
{
FreeLibrary(m_hRC);
}
and instantiation can simply be
void CParentWindow::onCallCustom()
{
CDlgCustom dlg(this);
dlg.DoModal();
}
The DlgCustom.dll will export the class CDlgCustom, that will manage itself the loading of resource-only dll DlgCustomRC.dll.
VERY important is to have resources in all those binaries that do not overlap.
So NO two dialogs with the same ID in the same executable space. I had to write tools that detects and reports such "resource clash" conditions.
If you want to do the job manually, load the library with "load library as data file" since is a resource dll, locate the resource with RT_DIALOG and corresponding IDD, create the DLGTEMPLATE and then use a CreateDialogXXX call. MFC does this - consult the implementation of CreateDialog (I think is in ../mfc/src/dlgcore.cpp).

It could be a custom control or ActiveX control that is not registered, and contained in the dialog. Other than that, I have no idea, and I can't help you since I cannot debug your code. Check again the usual problems (resources, dll paths, initialization problems etc.), it shouldn't be something that cannot be found on a careful analysis.

When i open a project provided by the manufacturer of an ip camera i get the following messages.
"The Active X control cannot be instantiated".
" 2 Active X controls could not be instantiated".
"Reinstall or Register the controls and try again".
How can i resolve this problem?

|

As error says, your project contains some activeX , which needs registration.
Try registering those.
|
|
|
|
|
|
You need to identify activeX in your project and use following line from commandline
regsvr32 /u "activeXFile"
RegSvr32[^]

Hi experts,
I want to add a com dll file in my project.I wtitten the below code to create a pst file in c drive.
Program compiled successfully
But the function Logon() goes fail and sows a exception :
"Unhandled exception at 0x7c812a5b in samp.exe: 0x0EEDFADE: 0xeedfade."
CoInitialize(NULL);
IRDOSessionPtr session;
HRESULT hr = session.CreateInstance(__uuidof(RDOSession));
session->Logon(" ",NULL,NULL,NULL,NULL,NULL);
session.Release();
what is the problem.Is there other way to add com dll in prject.
Plz tell

You should always check the returned HRESULT value, i.e.
if (FAILED(hr)))
{
}
and never use the pointer (even the smart ones  ) if the
CreateInstance failed.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

You can be connected to more than one site at a time. IE has an automation interface that you can use to enumerate the currently open URLs.

Hello, I am writing an outlook DLL, it is for a phone system and when a call is received I search through the outlook contacts (using called ID) find the person and open the contact in a window.
My problem is that this locks up outlook. When I open the contact under a button, e.g.
void __stdcall CAddin::OnClickButton2(IDispatch* Ctrl,VARIANT_BOOL * CancelDefault)
{
USES_CONVERSION;
CComQIPtr<office::_commandbarbutton> pCommandBarButton(Ctrl);
static Outlook::_InspectorsPtr inspectorsPtr;
static Outlook::_InspectorPtr inspectorPtr;
Outlook::MAPIFolderPtr pFolder = m_spApp->GetNamespace("MAPI")->GetDefaultFolder(olFolderContacts);
Outlook::_ItemsPtr pItems = pFolder->Items;
Outlook::_ContactItemPtr pContact = pItems->GetFirst();
inspectorsPtr= m_spApp->GetInspectors();
inspectorPtr = inspectorsPtr->Add(pContact);
inspectorPtr->Display(vtMissing);
}
This works fine, when I put the same code in my dll, e.g.
static void openContactOnCall(char* number)
{
static Outlook::_InspectorsPtr inspectorsPtr;
static Outlook::_InspectorPtr inspectorPtr;
Outlook::_ContactItemPtr contact = findContact(number);
if (contact)
{
// Contact is valid
inspectorsPtr= m_spApp->GetInspectors();
inspectorPtr = inspectorsPtr->Add(contact);
inspectorPtr->Display(vtMissing);
}
else
Debug("Didn't find contact");
}
A window opens with the contact but outlook then freezes. The contact must be valid as I see the correct name in the windows title bar. I have triggered outlook as it does open the window.
I've hacked around with this for sometime, and haven't got anywhere. I am clearly missing something quite fundamental but the fact the same code works under a button but not in the dll has got me confused, and shows that I do not understand something fundamental to how this should be working. Any help would be greatly appreciated.
Gavin.

Hi all,
I am partly through creating a console application that runs a Windows app. All this I have managed to perform, but the following I am unsure of.
I now need to bring the form to the current view (which I have achieved), then put the mouse pointer in a certain position then simulate pressing the left mouse button.
Can anyone suggest where I need to start looking to allow me to work this one out ?

Is mouse_event() of any help here?

G'Day Dave,
That sounds the GO, but what about getting the Mouse Cursor in the position I want ?
