Subject: Hook in DLL. Simple problem?
Hello.
Env: Windows NT 4.0 SP3, Visual C++ 6.0
I'm new to this hook thing.
I have created a DLL which contains a simple hook that captures all key
presses and store them in a file. The DLL was created using AppWizard. I
have export two functions from the DLL: InstallFilter and
KeyboardProc.
From a application I call the InstallFilter function. When debugging the DLL
I can see that the InstallFilter is called but SetWindowsHookEx(...) returns
NULL. When calling GetLastError() it returns 0. The
Filter function never gets called.
Here are some of the DLL code:
/* Filter definition */
LRESULT CALLBACK KeyboardProc(int code, WPARAM wParam, LPARAM lParam);
/* Globals */
HHOOK hKeybHook;
HOOKPROC hKeybProc;
/* DLL contructor */
CHookDLLApp::CHookDLLApp()
{
hKeybProc = (HOOKPROC)KeyboardProc;
}
/* Installer */
int CHookDLLApp::InstallFilter(BOOL fInstall) {
if (fInstall) {
hKeybHook = SetWindowsHookEx(WH_KEYBOARD, hKeybProc, m_hInstance, 0);
if (hKeybHook == NULL) {
char szStr[15];
int error = GetLastError();
AfxMessageBox(itoa(error, szStr, 10));
}
}
else {
UnhookWindowsHookEx(hKeybHook);
}
return (0);
}
/* Filter function */
LRESULT CALLBACK KeyboardProc(int code, WPARAM wParam, LPARAM lParam) {
char szOutputStr[255], szKeyCode[10];
szKeyCode[0] = (char)wParam;
szKeyCode[1] = 0;
strcpy(szOutputStr, "The user pressed: ");
strcat(szOutputStr, szKeyCode);
strcat(szOutputStr, "\r\n");
WriteDataToFile(szOutputStr);
return( CallNextHookEx(hKeybHook, code, wParam, lParam));
}

Use CWnd::SetTimer( ... ).
In timer callback function you can add a new portion of data into the

Environment: NT 4 VC 5
When using the CRichEditView and associated document how can I determine which
version of the rich edit class was instantiated?
Can I force the usage to version 2.0? Is this the default?
Thanks,

According to the MFC source code it uses version 1.0. And based on the
code you cannot force it to use version 2.0 unless you modify it and then
recompile it.

Subject: MDIChild derived from another class?
OS: NT4/SP4
DEV: MSVC++6/SP1
Hi. I have an MDI application, with a base MDI child window called =
CBaseFrame. I have another class derived from CBaseFrame called =
CServerFrame. The reason I want a base class between MDI children is =
that there are a quite a few similarities between them (functions as =
well as data), but there are fundamental differences that prevent me =
from creating MDI children dynamically from the same class.
The trouble is that I cannot instantiate a child window of the derived =
class. I get an assertion.
Here's the code and the details:
void CIRCApp::OnFileNew()=20
{
CMainFrame* pFrame =3D STATIC_DOWNCAST(CMainFrame, m_pMainWnd);
// create a new MDI child window
pFrame->CreateNewChild(
RUNTIME_CLASS(CServerFrame), IDR_IRCTYPE, m_hMDIMenu, m_hMDIAccel);
}
ASSERT =3D=20
BOOL CObject::IsKindOf(const CRuntimeClass* pClass) const
{
ASSERT(this !=3D NULL); <--------- HERE
// it better be in valid memory, at least for CObject size
ASSERT(AfxIsValidAddress(this, sizeof(CObject)));
// simple SI case
CRuntimeClass* pClassThis =3D GetRuntimeClass();
return pClassThis->IsDerivedFrom(pClass);
}
Any ideas?
