Hi,
Maybe today isn't my best day  but could anyone tell me what is wrong with this snippet ?
class CTest
{
public:
CTest()
{
(*(this)).lpFunc = &CTest::Write;
}
long Write(DWORD dwInfo)
{
...
}
long (*lpFunc)(DWORD);
}
I've got error C2440:
'=' : cannot convert from 'long (__thiscall CTest::* )(DWORD)' to 'long (__cdecl *)(DWORD)'
and when I change line: (*(this)).lpFunc = &CTest::Write;
to
(CTest::*lpFunc) = &CTest::Write;
I've got another error code:
error C2059: syntax error : '<tag>::*'
Generally I want to point on lpFunc a pointer to Write fuction but within class (I don't want to any globals).

notice the calling convention of the two parts of your operator = reported by the compiler.
you function Write has to be either static or global. the fact is that being a class member function implicitely adds it the this pointer parameter...

static need be there ONLY if it is not a member of the class.
|
|
|
|
|
certainly not !!!
compile the code and tell if the compiler complains...

That Write method MUST be static.
So solution is :-
class CTest
{
public:
CTest()
{
(*(this)).lpFunc = &CTest::Write;
}
static long Write(DWORD dwInfo)
{
...
}
long (*lpFunc)(DWORD);
}

That's not how you declare a member function pointer.
class CTest
{
public:
CTest()
{
lpFunc = &CTest::Write;
}
long Write(DWORD dwInfo)
{
...
}
long (CTest::*lpFunc)(DWORD);
};

Dear friends pls check the following program
I tried it in VC++ compiler and the size of structure is depending on the order of variables
What is the reason behind it
any one pls answer me
Thanks
// struct.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include "iostream.h"
struct st1
{
char q ;
int p;
}a1;
struct st2
{
char q ;
char r;
int p;
}b1;
struct st3
{
char q ;
int p;
char c;
}c1;
int main(int argc, char* argv[])
{
cout << sizeof(a1);
cout<

From MSDN...
"When applied to a structure type or variable, sizeof returns the actual size, which may include padding bytes inserted for alignment."

I need to convert vc++ code to net with the available dll files.How should i do this?
my existing code is in vc++ and i want to make web based application in asp.net using this code..
can u plz help me out how to do this..

You are talking of calling the unmanged code into the managed code. you will find some articles on this ,here on codeproject.
What do you mean exactly by conversion?
You will have to rewrite the code on the .NET platform if you don't go with the above option
Somethings seem HARD to do, until we know how to do them.

rename .cpp files to .net
You will have to rewrite the whole thing in the language that you want.

Dear VC-master,
Thank you for your attention,
In my MDI project, the based view is CFormView. named CMyView.
the problem is,
in CMainFrame class, SetValue()was defined.
in CMyView class, public function SetEdit(true)was defined.
in myview.cpp, if I use below, it is ok.
void CMyView::OnSendValue()
{
CMainFrame *pMainfram = (CMainFrame *)AfxGetMainWnd();
pMainfram->SetValue(0x55);
}
but if In MainFrm.cpp
void CMainFrame ::OnSendValue()
{
CMyView *pMyView= (CMyView *)<b>GetActiveView();</b>
pMyView->SetEdit(true);
}
it can build successfully, but <b>failed execute.</b>
how to call the function/variable in active view?
|
|
|
|
|
My first question is have you verified that the CMainFrame::OnSendValue() function is even getting called?
Run this in Debug mode...
void CMainFrame::OnSendValue()
{
TRACE("CMainFrame::OnSendValue() called\n");
CMyView* pMyView=(CMyView*)GetActiveView();
pMyView->SetEdit(true);
}
Do you see the output from the TRACE in the output window?

Hi all,
I want to know if it is possible to write a MFC DLL which can perform the following task:
- Check to see if the process / program arleady exists.
- And when return a code to indicate if it is there or not.
The problem is I have the code to do this. But I have no idea if it is possible in a dll. Cause in the MFC DLL i'm truggling to call the system DLL which has all the methods that I need to communicate with the processes.
If anyone could help or point me to a site on the net.
Thanx alot

If it can be done in an MFC EXE then it can be done in an MFC DLL.

That is my current signature, it is not for anyone specific. See your "Settings" page, you have a space for one also.
Just a little advice, if you are going to use the internet as a source of help you should not be so easily angered.

yes its not problem(i think) only you need to return detaily from process to your program like(name,memory usage,thread,...)

In DllMain you can find the reasons like Process Attach, Process Detach, Thread Attach, Thread Detach. You can do it there.
In MFC Dll you might have to do it in InitInstance override.

In my app I am using the FaxStartPrintJob API from WinFax.dll to send faxes. But I recently upgraded from VC6 to VC8 and in the upgrade I deleted the old Feb 2003 PSDK that contained the Winfax.h and winfax.lib files. Now VC8 and the new PSDK does not contain those files so I am unable to use that API unless I get a copy of those files somewhere.
What is the new method that one has to use to send faxes that replaces the FaxStartPrintJob API? I really liked being able to simply print to a fax DC so I am hoping the new method is just as easy.
You may be right
I may be crazy
