Sleep(1000);
if ( need_Action )
{
..do action..
}
}
Thanks!!!

Why not make it a windows service?

Unless you can respond to the WM_QUERYENDSESSION and/or WM_ENDSESSION messages, you'll have no way of knowing when Windows is shutting down or when a user is logging off.

hi!
i would like to implement a html-site - a small html-template with a few controls like a slider, buttons and so on...
the user should be able to change the look of the application by just editing the html-template.
from within c++ i want to get info, if the user clicks a control (button, slider...) and i want to change eg. the position o f a slider, content of a listbox, text of a button...
the template has to be embeded in the main application... the main-framework should be a CDialog
is it possible to do this without requesting the user to install ie6 or something?
the app should also work, if just a minimum iexplorer is installed.
or is there a way to do this without ie?
how do i interact with the html-template from within my c++-code?
has anyone a idea or tutorial? maybe some demo-classes on thecodeproject.com? i actually don´t know, what i have to search for ;o)
cheers,

Hi
Let's say I defined a global const in a header file (which will be #included by many files) as follows:
const int MAX_CLIENT = 1000;
My question is, will the compiler replace each occurence of MAX_CLIENT with 1000? Should I declare MAX_CLIENT as static const instead? And will the same rule apply if MAX_CLIENT is not an int, but a char array?
Thanks!

Yes and no  . It's not a direct textual substitution like a #define, but when the compiler is optimising code it will substitute the variable reference by its value.

If your header file is used by multiple source files, then yes, otherwise you'll get a bunch of multiple initialisation errors from the linker.

Yes. If it's a char* though, such as char *message = "Message", then make it fully constant, ie. const char * const message = "Message", otherwise the compiler might not treat it as a true constant.

i have an existing library which provide me the support for calling varied functions. now i ahve to add the functionality of two new api's in that same vc project which eventually will be called by the autocad application. i ahve with the objectarx require to create the glue layer and the arx application which will hwlp me call the funtions in vc through autocad. even though i have created a new library which defines the two api's but on calling these functions through VC++ it shows me an error that it cannot find the new api's called even thought the new library has been included in the project setting. please guide as to where am i missing the link as there are quite a few things involved in interacting autocad with vc.

Have you set the include and lib paths so that they cover the location of your libraries and headers?

thanx for thr reply but i am a bit uncertain. if u r mentioning the include and library paths for object arx, then they have been included and also the path for the library(for the new API's that i need to include) has also been included in the project settings. hence, plz be more specific as to what include and lib paths are u talking about. looking forward to ur reply but still thanx in advance.

I was refering to the directory settings under Tools->Options. You can specify global settings for include paths and library paths.
If you have these settings can you give the exact error message you are getting when you try to compile.
Oh, just a thought, Have you tried a complete clean and rebuild?
Ant.

it is said that there are some hooks that can only be set in the dll(means a global hook) not be set in the application(a local program hook),is it right?
if true,could you tell me which hook can only be set in dll,thanks a lot

Any hook which can get called in the context of a thread that does not belong to the process that installs the hook must be in a DLL. So basically, any system-wide hook. Thread-specific hooks that only hook threads in the current process can reside in the application.

sorry to interupt to you again,I don't understand what you said? please give my a clear answer,thanks

If the hook is a global hook, it must be in a DLL. If it is not a global hook, it can be in your application.

I want to know which hook can only be a global hook not be a hook for one program

Well, have you tried MSDN? The documentation for SetWindowsHookEx()[^] tells you exactly what you want!

I am using TrackPopupMenu() to display a popup menu and allow a user to make a selection. I would like to have an event occur (have a method called) each time the selected item in the menu changes. In other words, as the user moves the mouse up and down the menu, as a menu item becomes selected (not clicked, simply highlighted), I would like an opportunity to take an action (such as display information regarding what will occur if the user selects that menu option).
Thanks

I struggled whether to post this question here in in the COM forum, but I ultimately decided the answer is more of a generic C++ question rather than C++ so I am posting it here
MFC6 has the CHtmlView class and like most classes in MFC using visual studio you can quickly add an handler for the events fired by the IWebBrowser2 actually according to MSDN (AFAIK)
it's the WebBrowser...cuz IWebBrowser2 doesn't seem to have events 
BEGIN_EVENTSINK_MAP(CHtmlView, CFormView)
ON_EVENT(CHtmlView, AFX_IDW_PANE_FIRST, 104 , OnDownloadComplete, VTS_BSTR)
END_EVENTSINK_MAP()
Then in your derived CHtmlView class you override a virtual function OnDownloadComplete and voila you now have the ability to tell when a document has been fully loaded.
How does MFC accomplish this task of event sinking, etc all with a couple of macros? I looked at the macros and I couldn't make anything of them 
Basically I want to use this same technique, but on a different interface...so I can avoid all the mumbo jumbo that goes along with capturing events sent from IHTMLDocument2, etc...
Anyone care to shed some light on how this is accomplished?
Thanx in advance
Cheers

Is it possible? And where To Find the full information about this Dll, and it's possibilities (IXMLDOMdocument, IXMLDomNode.....)?
I've already posted this question, but no one answered.
So, please help.

Try "save" function in IXMLDOMDocument.
You just have to give the File Name as the parameter.
|
|
|
|

Yes , i tried this function, and i tried to change some data in existing xml file - and i succeded. But when i try to create a NEW XML file (insert new Nodes - this is my problem). Could you please write a short example?
Thank you.

IXMLDOMDocument *pDomDoc;<br />
<br />
CComVariant vFileName("C:\\MyXML.xml");<br />
VARIANT_BOOL vBool;<br />
pDomDoc->loadXML(L"<root><child></child></root>",&vBool);<br />
<br />
VARIANT V;<br />
V.vt = VT_I4;<br />
V.lVal = 2;<br />
<br />
hResult = pDomDoc->createNode(V,strName,L"",&pXMLDOMNode);<br />
<br />
IXMLDOMElement *pDomElement;<br />
pDomDoc->get_documentElement(&pDomElement);<br />
<br />
IXMLDOMNodeList *pDomNodeList;<br />
pDomElement->get_childNodes(&pDomNodeList);<br />
<br />
IXMLDOMNode *pChildNode = NULL;<br />
pDomNodeList->nextNode(&pChildNode );<br />
<br />
IXMLDOMNamedNodeMap *pXMLAttributes = NULL;<br />
pChildNode->get_attributes(&pXMLAttributes);<br />
<br />
IXMLDOMNode *pXMLAttrNode = NULL;<br />
pXMLAttributes->setNamedItem(pXMLDOMNode,&pXMLAttrNode);<br />
pDomDoc->save(vFileName);

Hi dear!
I'd like to put a scrollbar's tap on last position.
My program created much some results files since it runned for a couple hours.
So It is tiresome to find last test result's file because there are a lot file in that directory.
Every time I had to move to last position in scroll bar even though annoying.
-------- problem section in my program -------
CFileDialog dlg(TRUE, sFi , NULL, OFN_HIDEREADONLY|OFN_NOCHANGEDIR|
OFN_ALLOWMULTISELECT,//|OFN_VALIDATE, NULL, this);
SCROLLINFO scrInfo;
int nPos, nMin;
HWND hDlg = dlg.m_hWnd;
dlg.GetScrollRange(SB_HORZ, &nMin, &nPos);
nPos = scrInfo.nMax;
dlg.SetScrollPos(SB_HORZ, nPos);
This didn't fine out right valuse for nMin and nPos.
I would be very happy if anyone replay me any answer concering it,
I've wasted a couple week already.
yours sincerely
