I want to hook COMCTL32.DLL's import function table or I want to replace the GetScrollBarInfo API 's enter address in user32.dll , because win98 share system DLL in the same address space and protect it, how can I do this??

how to enable a system menu again from another class
this part works fine ...
void Cfirstw32mfcDlg::OnSysCommand(UINT nID, LPARAM lParam)
{
if ((nID & 0xFFF0) == IDM_ABOUTBOX)
{
CAboutDlg dlgAbout;
dlgAbout.DoModal();
}
else
{
CDHtmlDialog::OnSysCommand(nID, lParam);
}
if ((nID & 102) == IDS_ZONENAME)
{
CAddzonename* pDialog;
pDialog = NULL;
pDialog = new CAddzonename(this);
if(pDialog != NULL)
{
BOOL ret = pDialog->Create();
if (ret)
{
EDIT2 =("done");
UpdateData(FALSE);
CMenu* pSysMenu = GetSystemMenu(FALSE);
pSysMenu->EnableMenuItem(IDS_ZONENAME,MF_BYCOMMAND | MF_DISABLED | MF_GRAYED);
}
if(!ret) //Create failed.
AfxMessageBox("Error creating Dialog");
pDialog->ShowWindow(SW_SHOW);
}
else
AfxMessageBox("Error Creating Dialog Object");
//CAddzonename dlgAbout;
//dlgAbout.DoModal();
}
else
{
CDHtmlDialog::OnSysCommand(nID, lParam);
}
}
..........................................................
doesn't work, but doesn't return errors either
void CAddzonename::OnBnClickedOk()
{
/*Cfirstw32mfcDlg**/ CMenu* pSysMenu = GetSystemMenu(FALSE);
pSysMenu->EnableMenuItem(IDS_ZONENAME,MF_ENABLED);
DestroyWindow();
}
how do i enable the the menu item again, witch got disabled by pressing on it
kind regards,
marco

with

BaseType=char,
StringTraits=StrTraitMFC<char>

No constructor could take the source type, or constructor overload resolution was ambiguous
what am i doing wrong?
kind regards,

I'm assuming that your application overrides WriteProfileString to take a CAddzonename pointer. AfxGetApp will return an instance of the base class, you need to cast it to the specialised class that contains this method. as it stands, it's trying to call the base class method, as that's all it can see.
I think. It's kind of hard to wade through all of that badly formated code.

//CAddzonename* m_Zonename; <-- seems to be good, but how to use it??
if(m_Zonename)
{
AfxGetApp()->WriteProfileString("Settings", "Zonename", m_Zonename);
}
returns ...
j:\Visual Studio Projects\win32\firstw32mfc2\firstw32mfcDlg.cpp(224) : error C2065: 'm_Zonename' : undeclared identifier
BTW, i tried that before

That's a whole different problem. m_Zonename does not exist in the class where you're trying to use it, obviously.

If you're going to be sarcastic, you can get stuffed.
If you don't know how to declare or scope a variable, I suggest buying and reading C++ for dummies before asking questions here.

i'm not getting sarcastic, but dont tell me it's obivious.
i'm trying to find out how, i'm already reading stuf the whoile weekend andf i have read about creating a global variable, but when i copy(adapting the code afcourse) the code, visual doesn't accept it.
somehow.

Global variables are bad design anyhow. However, in C++, to declare something as global ( that is, not within the scope of any class ), it will still only be visible in files where the file that declares it is included. I found the best way to do this is to declare stuff in stdafx.h. But a better option would be to declare it within the class that you're trying to get at with AfxGetApp(), although you still need to cast that, as I said before.

i tried to cast like this...
CAddzonename* m_Zonename;
//CString m_Zonename2 = m_Zonename;
and it returns this ...
j:\Visual Studio Projects\win32\firstw32mfc2\firstw32mfcDlg.cpp(222) : error C2440: 'initializing' : cannot convert from 'CAddzonename *' to 'ATL::CStringT<basetype,stringtraits>'
with
[
BaseType=char,
StringTraits=StrTraitMFC<char>
]
if i do this ...
CString m_Zonename2;
CAddzonename* m_Zonename;
m_Zonename2 = m_Zonename;
j:\Visual Studio Projects\win32\firstw32mfc2\firstw32mfcDlg.cpp(222) : error C2679: binary '=' : no operator found which takes a right-hand operand of type 'CAddzonename *' (or there is no acceptable conversion)
...................................................................
CAddzonename* m_Zonename;
//m_Zonename2 = m_Zonename;
//if(m_Zonename)
//{
AfxGetApp()->WriteProfileString("Settings", "Zonename", m_Zonename);
}
this will return ...

Duh. Why do you expect to convert a string from an instance of your class ?

Bloody hell. Follow my advice, or stop asking me.

HRESULT Cmfc2htmlDlg::OnButtonOK(IHTMLElement* /*pElement*/)
{
OnOK();

}
HRESULT Cmfc2htmlDlg::OnButtonCancel(IHTMLElement* /*pElement*/)

you can do this with many ways as follows:-
1- Yourclass::OnOk()
{
// make it empty
}
2- use SetwindowHookEx function to capture Keyboard keys
and u can compare the wpararm parameter in your callback function if it =13 then Enter key has been pressed and you
can do any thing you need.
after this if broblem is found contact me on faroq_tam2004@yahoo
to send to you some source code

Hello,
I'm doing a multithreaded application that creates threads using the _beginthreadex api.
At some point I need to wait for the thread to exit (it exits normally) using the WaitForSingleObject api.
When I'm debugging , the thread function just exits normally. After the thread has exited, the <waitforsingleobject< code=""> api does not return, but still waits on the thread handle.
I'm not signalling the thread handle (which I don't think I should) and the thread has default access.
Is there anything that I should do with the thread handle before the thread exits?
Thanks in advance.
Multiply it by infinity and take it beyond eternity and you'll still have no idea about what I'm talking about.
