Here is the whole code...
typedef void (* TFunction)(int param1, ...);
void MyFunction(TFunction pF)
{
pF(90, 30, 20, 10);
};
void OtherFunction(int param1, ...)
{
// Do something
}
// Calling...
...
MyFunction(OtherFunction);
...

thanks..
c code is a little misunderstood for me... i will describe the problem i have in c++ maybe you can write the proper example code :
the class CBDRMainDlg contains the called method :
class CBDRMainDlg
{
public
.
.
void ClearIt();
};
the class also contains a function called add that one of its parameters is a pointer to the method ClearIt:
class CBDRMainDlg
{
public
void Add(
.
.
void ClearIt();
};
out side the class in on other class i am defining an object of the class:
...
...
CBDRMainDlg dlg;
dlg.DoModal();
see all the remarks above, can u replace them with the proper code?
thanks again for all your help
Cheers

This is sintactically correct:
class CBDRMainDlg;
typedef void (CBDRMainDlg::* DlgMethod)(void);
class CBDRMainDlg
{
public:
void Add(DlgMethod method)
{
};
void ClearIt()
{
printf("Clear It");
};
};
int main(int argc, char* argv[])
{
CBDRMainDlg dlg;
dlg.Add(CBDRMainDlg::ClearIt);
return 0;
}
... but i can't figure out how to call the method inside 'Add' since the compiler needs to push the this pointer in the stack before make the calling. It is possible using inline asm but i think that is not the best solution...
Why do you want to call methods this way? I think you can do that using virtual methods...

I have a problem, I´m trying to use the IP address control in a VC++ 5.0 project. The code should be ok, but, when the resources are to be compiled, it does not recognise the SysIPAddress32 control.
Does anybody have a solution for this, i.e. do I have to set the control (in the resource editor) as a custom control, and if yes, how?
Thanks in advance
Phil
bum... and I thought I´d got rid of all the bugs

Sorry, but if you look at the date, this is over 6 years ago, and for the life of me I can't remember how I got it to work... I've moved onto "Greener Pastures" now

Hi,
I need some help please.
I tried to figure it out, but with no success so far.
Why do I get E_INVALIDARG when I try to use the appendChild Function.
This is my source code:
IHTMLElement* pHTMLElement;
IHTMLElement* pNewHTMLElement;
IHTMLDOMNode* pHTMLDOMNode;
IHTMLDOMNode* pNewHTMLDOMNode;
IHTMLDOMNode* pNew2HTMLDOMNode;
IDispatch* pDisp;
v.vt = VT_BSTR;
v.bstrVal = SysAllocString(L"HEAD");
hResult = pIHTMLElementCollection->tags(v,&pDisp );
if (hResult == S_OK)
{
hResult = pDisp->QueryInterface(IID_IHTMLElementCollection,(void**)&pIHTMLElementCollection);
if (hResult == S_OK)
{
pIHTMLElementCollection->get_length(&lCollectionSize);
v.vt = VT_I4;
v.lVal = 0;
hResult = pIHTMLElementCollection->item(v,v,&pDisp);
if (hResult == S_OK && pDisp != NULL)
{
hResult = pDisp->QueryInterface(IID_IHTMLElement,(void**)&pHTMLElement);
if (hResult == S_OK)
{
hResult = pHTMLElement->QueryInterfa(IID_IHTMLDOMNode,(void**)&pHTMLDOMNode);
if (hResult == S_OK)
{
bstrTemp = SysAllocString(L"BASE");
hResult = pIHTMLDocument2->createElement(bstrTemp, &pNewHTMLElement);
SysFreeString(bstrTemp);
if (hResult == S_OK)
{
bstrTemp = SysAllocString(L"href");
v.vt = VT_BSTR;
v.bstrVal = strWebPageDomain.GetBuffer();
hResult = pNewHTMLElement->setAttribute(bstrTemp, v, 0);
SysFreeString(bstrTemp);
if (hResult == S_OK)
{
hResult = pNewHTMLElement->QueryInterface(IID_IHTMLDOMNode,(void**)&pNewHTMLDOMNode);
if (hResult == S_OK)
{
****************************************************************************
hResult = pHTMLDOMNode->appendChild(pNewHTMLDOMNode, &pNew2HTMLDOMNode);
****************************************************************************
}
}
}
}
}
}
}
}
}
}

oh, hi fadi
there are some types of IOCTLs, the standard ones and the custom ones.
to find out the standard ones, read the DDK and/or the DDK header files.
the custom ones are a problem...
good luck,
alex

<br />
szBuffer[0] = '\0';<br />
<br />
strncpy(szBuffer, cMediaFileInfo.szFrameRate, strlen(cMediaFileInfo.szFrameRate) - 4);<br />
<br />
<br />
szBuffer[strlen(cMediaFileInfo.szFrameRate) - 4] = '\0';<br />
double dFramerate = atof(szBuffer);<br />
dFramerate is always 0.

Your code snippet does not show the allocation for szBuffer. Are you show it is at least as large as say 6 or more bytes?

I used CHtmlView to display html page.
And I create a new thread as my work thread.
In my work thread , I call m_pMyHtmlView->Navigate2(...) to navigate to a html page.
The problem is when my program runs,the downloadComplete isn't be done sometime. And the URL I open is the file in the local computer with my program. So I don't know why the download is fail?
I try to debug it,and find the function run like under:
OnBeforeNavigate2()
DownloadBegin()
DownloadComplete()
DownloadBegin()
-------------------if error happens,the under don't be done
OnTitleChange
NavigateComplete()
DownloadComplete()
OnTitleChange
DocumentComplete()
Why after execute DownloadBegin() not execute DownloadComplete()?
Does anybody meet the status like this?
The error doesn't happen every time.Sometimes it happens after program runs 5 minutes. Some time the program work well whole day.
When the error happens,the thread of CHtmlView doesn't work.Even if the work thread call's m_pmyHtmlView->Navigate2(...),the thread of CHtmlView does't respond.It seems that thread was blocked.

Design the necessary classes for a program that would allow a state government office to track vehicle registrations/license plates. The program should at least allow tracking of the Registrant, the Vehicle, and the Registration Details including fees paid.
What are 4-7 classes I could use to write this program?

We aren't here to do your homework for you. From the FAQ:It is generally OK to ask questions about a homework assignment, but you must at least try on your own first. Don't just post the assignment description; that looks like you want the forum readers to do the assignment for you. Start the program yourself, and when you get stuck, ask a specific question and, again, include the code that isn't working.

GEE THANKS..... too bad i did start it myself and i was asking for some help to see what response I would get. I was stuck and confused about what classes to use and thats why I asked the question. How else would anyone know what to write back if I didnt include the problem. Thanks there smart guy.

The way you formed your question (no source code provided, no explanation of what routines you needed help with, no examples of compilation errors, etc, etc, etc) told us, basically, "I have an assignment that I can't do and I want you guys to do it for me!".
Instead of coming off like a cocky bee-yotch, why don't you just explain (preferably at the code level) what you are having difficulty with?

You just blew off one of the best resources on this site. Why don't you try reading your documentation instead of insulting people on this site (if you want to insult, go to the soapbox!!!!!)?

In this context, "i did start it myself" is not a phrase one should apply if the only work seemingly carried out is to have read the question.
The whole point of the assignment is for you to use that squishy stuff between your ears -- there aren't classes out there for everything, that's why you need to think about defining the problem further (analysis), and then modelling a solution (design). By encapsulating behaviour, you define the classes appropriately.
It might have come across a little better if you hadn't joined CP solely to ask the question...

Nicely done.
Michael Dunn is one of the best sources for help on CP. and you decided to be a whiny punk and lip-off at him.
OOPS!
Maybe if you had said:
"These are the classes I think I should use, what you do guys think?" Or SOMETHING that shows that you've actually *TRIED* to solve the homework question problem.
The kindest thing you can do for a stupid person, and for the gene pool, is to let him expire of his own dumb choices.
