Is this the first time Visual C++ 5 has this error?
As an experiment, compile the MFC project using static DLL linking.

Your program compiled/linked with different (most probobly newer) version of MFC
P.S. use depends.exe to find out what dll/function is missing

It isn't my first time i run a vc5 project.
I have vc5 + vc6 on 1 computer installed.
before i run vc5 i replace a .dll file (don't remember which one) and it always seemed to work. But now it gives me that error.
And what is 'depends.exe'?

It's a Visual Studio tool. It shows the dependencies of a EXE or DLL.

See if MSDN article Q168847 is of any help.

Hello,
YARSQ (yet another ridiculously silly question) - please bear with me.
Can someone help me write a simple program that can be used to
1. kill a process in the taskbar,
2. will work on all windows* platforms
3. implemented in c/c++
I have a fairly cloogy signaling mechanism between programs to find out which ones are alive, etc - but ideally, I would like a clean start on all processes from a master.
Somewhat related topic, but what is the windows call to very reliably find out - given a process/exe name - if a instance of it is already running.
As many of you may have figured out, I am working with programs whose owners have long been dead, figuratively anyway  Answers much appreciated.

One solution is EnumProcesses(). You may need other API to get module names. Go to MSDN. Open the process and close it via quit message. Another solution is to terminate the process.

Terminate project ? The processes are detached. Thanks.

i try to pass the following global function pointer to a c library function (cvcamSetProperty) which required the third parameter as callback function pointer.
---------------------------------------------
BOOL CXFaceRecognitionDlg::OnInitDialog()
{
//
// some code had been eliminated
//
// making call the the c library function
cvcamSetProperty(0, CVCAM_PROP_CALLBACK, callback2);
}
void callback2(IplImage* image)
{
}
---------------------------------------------
the compilation stage works fine and no problem at all.
however, when i try to pass the member function pointer, it failed 
---------------------------------------------
BOOL CXFaceRecognitionDlg::OnInitDialog()
{
//
// some code had been eliminated
//
// making call the the c library function
cvcamSetProperty(0, CVCAM_PROP_CALLBACK, &CXFaceRecognitionDlg::callback);
}
void CXFaceRecognitionDlg::callback(IplImage* image)
{
}
---------------------------------------------
here is the error message which i obtain when i try to compile the above code:
D:\Documents and Settings\Administrator\Desktop\XFaceRecognition\XFaceRecognitionDlg.cpp(144) : error C2664: 'cvcamSetProperty' : cannot convert parameter 3 from 'void (__thiscall CXFaceRecognitionDlg::*)(struct _IplImage *)' to 'void *'
There is no context in which this conversion is possible
may i now how can i solve this problem?
thank you.
regards

I think it should be static function, if it is a member of a class(plus check the actual signature it might need to be __cdecl)
|
|
|
|
|
Declare the callback function as static function of the class
class CXFaceRecognitionDlg:: .......
{
:
static void callback(IplImage* image);
:
}
and i think you should not use the & for the call, just use the static function name :
cvcamSetProperty(0, CVCAM_PROP_CALLBACK, CXFaceRecognitionDlg::callback);

Hi all,
I'm trying to catch WebBrowserEvents from within the toolband. This is basicaly the code im using, but it doesnt seem to work. Has anyone done this before and/or sees what im doing wrong.

public CComCoClass<ctoolbar, &clsid_toolbar="">,
public IDeskBand,
public IObjectWithSiteImpl<ctoolbar>,
public IInputObject,
public IDispatchImpl<itoolbar, &iid_itoolbar,="" &libid_guciolib="">,
public IDispEventImpl<0, CToolbar, &DIID_DWebBrowserEvents2, &LIBID_SHDocVw, 1, 0>
...
BEGIN_SINK_MAP(CToolbar)
SINK_ENTRY_EX(0, DIID_DWebBrowserEvents2, DISPID_ONFULLSCREEN,OnFullScreen)
SINK_ENTRY_EX(0, DIID_DWebBrowserEvents2, DISPID_BEFORENAVIGATE2, BeforeNavigate2)
END_SINK_MAP()
...
public:
STDMETHOD(OnFullScreen) (BOOL FullScreen);
STDMETHOD(BeforeNavigate2) (LPDISPATCH pDisp , VARIANT* URL,VARIANT* Flags, VARIANT* TargetFrameName,VARIANT* PostData, VARIANT* Headers, BOOL* Cancel);
...
STDMETHODIMP CToolbar::FullScreen(LPDISPATCH pDisp, VARIANT *URL, VARIANT *Flags, VARIANT *TargetFrameName, VARIANT *PostData, VARIANT *Headers, BOOL *Cancel)
{
::MessageBox(NULL,"ONFULLSCREEN event!","IE",MB_OK);
return 0;
}
STDMETHODIMP CToolbar::BeforeNavigate2(LPDISPATCH pDisp, VARIANT *URL, VARIANT *Flags, VARIANT *TargetFrameName, VARIANT *PostData, VARIANT *Headers, BOOL *Cancel)

Hi all,
how can I customize the botton in the windows function MessageBox()?
Is there a class to do this?
Thanks
Piccinaco

define "customize the button"
|
|
|
|
|
One solution is to design your own simple message dialogbox.
Kuphryn
|
|
|
|
|
No, you get the standard buttons. If you need custom ones, you'll have to make a separate dialog box.
|
|
|
|
|
There is no "official" way to do so, and most people that tried found it easier to "clone" the windows message box, rather than hooking the existing one.
You find a few imlementations on CP.

Been playing around with DnsQuery() but i can't find a way to convert from IP4_ADDRESS to a string.
Hoping you can help me.

Microsoft provides functions to retrieve the four bytes of the IP adress. So call them one after another, and use a CString or strcat to concatenate the result.

Many thanks, i've got it working now.

Does gethostbyaddr() or inet_ntoa() work for you?
|
|

|

Not tried them yet, will have a go in a few minutes.

I have a question regarding a MSComm Control on a simple dialog form with a thread that exits with an error code 0x1.
A new project created with VC++ 6.0 App Wiz, simple dialog, with a MSComm control and a variable mapped to m_Commm and one command button, OpenClose.
In 'OnOpenClose' place:
m_Comm.SetCommPort(1);
m_Comm.SetPortOpen(true);
// Doesn't seem to matter whether I
// put additional code in here or not.
m_Comm.SetPortOpen(false);
While using an external analyzer, I can see that the port in question is opening and closing, in fact with additional code I can send and receive data through this port, but always when I close the port the debug window shows a message that the thread has closed with error code 0x1. As near as I can tell this corresponds to ERROR_INVALID_FUNCTION.
So my question is; Do I actually have an invalid function, or am I misreading the thread error message?
