This is not advisable. What is it exactly that you are trying to do?

for access to main dialog you can use GetParent but you said "that is not derived from any MFC class"

In your own class create a member to your edit control (like CEdit* m_pEdit).
Then create a function to set the member (like SetEdit(CEdit* pEdit) { m_pEdit = pEdit; } ).
Then in your own class, use m_pEdit->SetWindowText(...) or GetWindowText(...).
Does that work?

Why do you need to do that? A WORD representaton of a CString does not make sense.

You can use atoi (or strtoul always forget about that too :->) to convert the string to an integer, then cast it, but it doesn't make sense to convert a filepath to a number (unless the path is a number, I guess).

I'm curious whether it is possible to compile your apps for Win 3.x with VC6-8. My first idea would be to remove the WIN32 from the preprocessor definitions, but that would be too easy.
|
|

|

No, I think you would need one of:
- Visual C++ 1.52
- Borland C++ 5.02 (not Borland C++Builder)
- Open Watcom
Those are the only compilers I know of off-hand that can make 16-bit Windows apps.

maybe he doesn't need to keep the 16bits compatibility; only rebuild the application with a modern compiler.
I can't help since I never coded win 3. applications.

Windows 3.1 == 16-bit applications only, unless you use the Win32s add-on that Microsoft came out with near the end of Windows 3's lifespan. I understand that Win32s programming has, um, issues.

Yes, I remember this from doing technical support on mathematical software products such as Mathsoft's Mathcad about 12 years ago.

No, VC 1.5 was the last VC that made 16-bit binaries. Your other option is to use VC 4.0 and make a Win32s app, then install Win32s on the Win 3.1 machine. (I forget when Win32s support was removed, it was either VC 4.1 or 4.2)

I am trying to add an interface to my CFormView and CRecordView classes but not getting the results I would expect. Some code snippets...
// MainFrm.cpp
void CMainFrame::SelectView(UINT ViewID) {
...
TRACE("-1-\n");
((CViewControl*)pNewActiveView)->activate(); // <-- not working
//((CMasterView*)pNewActiveView)->activate(); // <-- this does work
TRACE("-2-\n");
}
// ViewControl.h
#pragma once
#include "StdAfx.h"
class CViewControl
{
public:
CViewControl();
~CViewControl();
virtual void activate();
};
// ViewControl.cpp
#include "StdAfx.h"
#include "viewcontrol.h"
CViewControl::CViewControl()
{
}
CViewControl::~CViewControl()
{
}
void CViewControl::activate()
{
TRACE("-----CViewControl::activate()\n");
}
// and here is one of the view clases that use it...
// MasterView.h
class CMasterView : public CRecordView, public CViewControl
{
...
public:
virtual void activate();
...
// MasterView.cpp
void CViewControl::activate()
{
TRACE("-----CMasterView::activate()\n");
}
..with the following output:
-1-
-2-
...expected:
-1-
-----CMasterView::activate()
-2-
A side note: If I make ~CViewControl() virtual, I get the following output:
...
-1-
Warning: calling DestroyWindow in CWnd::~CWnd; OnDestroy or PostNcDestroy in derived class will not be called.
Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call. This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention.
Now I know there are different ways of doing the same thing, Create my on CMyRecordView and CMyFormView classes, but would like to know why the above code is not working like it should.
Any insight would be appreciated.

is there compiler options for compiling executable to use both processors in double core architecture under VC2003

nope, design your program to be multithreaded...
|
|
|
|

Are you wanting the compiler to use both processors to compile your program, or are you wanting your program, when running, to use both processors?

While the previous posters are correct, there is a code generation option that you need to select to enable multi-threading and link with the correct run-time libraries.

Dear all,
I want to make a windows service in vc++ 6.0 so that i don't have to double-click the executable at every bootup. probably, it is feasible in VC.NET but i want to do the same in vc 6.0
To be clear, for eg. I want to make a timer that would start automatically when windows starts up; runs in background and alerts at every 5 seconds. I would want to be able to control its behaiour from windows services or msconfig.
please help me

You do not have to create a service to get this functionality. You can add a "regular" program to the following registry key:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

Do events return values or are they always void in nature?

An event is something that happens. You can have functions that respond to those events, however.

If you mean "events" as a callback interface in COM, this is no different from other interfaces, i.e. all methods return a HRESULT.
If you mean "events" as an ActiveX source interface, the function can return any type that is compatible with automation and can be represented within a VARIANT.
If you mean "event" as a message, since windows is event-driven, all message handlers return a LRESULT.
Have I missed some interpretation of "event"?
Hope this helps
