Trying to search the web in a loop, hitting the search engine with a new query with each iteration (with thousands of terms for this particular application). Don't know frankly if that's even allowed, as google kicks you off if you try to do it. But the following code below uses the COM IWebBrowser2 interface to an open InternetExplorer. Don't know if that is considered antiquated or there's a faster way to do it, because right now I'm just getting about a page per second. Is there a faster way than the following:
SHDocVw::IWebBrowser2Ptr brwsr = NULL;
.
.
.
brwsr = SHDocVw::IWebBrowser2Ptr(spDisp);
.
.
.
strcpy(srch_engn,"http://www.mysearch.com/search/GGmain.jhtml?searchfor");
sprintf(szURL,"%s=%s+%%22",srch_engn,q_misc);
char* szSrch = szURL+strlen(szURL);
while (1) {
strcpy(szSrch,getNextSrch(...));
BSTR bstr = ConvertStringToBSTR(szURL);
brwsr->Navigate(bstr);
VARIANT_BOOL busy;
READYSTATE rs;
while(1) {
Sleep(200);
brwsr->get_Busy(&busy);
if (!busy) break;
brwsr->get_ReadyState(&rs);
if (rs == READYSTATE_LOADED) break;
if (rs == READYSTATE_COMPLETE) break;
}
brwsr->Stop();
.
.
.
}
|
|
|
|
|
After the Stop statement above, here's how I process the returned page (as I guess that might be the bottleneck):
if (rsltDoc = IHTMLDocument2Ptr(brwsr->GetDocument())) {
HRESULT hr = rsltDoc->get_body(&body);
if (!FAILED(hr)) {
BSTR bstr_b;
hr = body->get_innerText(&bstr_b);
if (!FAILED(hr)) {
char* szBody = ConvertBSTRToString(bstr_b);
if (!strstr(szBody,szNotFound)) {
pf_fmt(szSrch);
fprintf(f,"%s\n\n",szSrch);
printf("%s\n\n",szSrch);
bMatch = TRUE;
}
delete [] szBody;
SysFreeString(bstr_b);
}
}
}

You can use RegSetValueEx().

Thanx, I know about registry setting.
I'm trying using the GLOBAL_POWER_POLICY and if it will not help, maybe the reg. settings. Can you post me the place where to find the reg. entry ?

It will be in the following value:
HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Power\Heuristics

.... but the problem is, the system won't give any reaction to the change, in power options is still the old setting

If you are merely trying to keep a system 'alive' consider investing these coding tips into your application, from the MDSN topic: Using Power Management, instead of disabling the hibernate policy altogether, just keep system awake while your program is running. If user does NOT run your program, then there might be no reason the system should not hibernate. If yu need to perform some task at a scheduled time, then let it hibernate, but consider setting a waitable timer. This will wake system up and your process will resume.

I've tested it doesn't flick without popping up the context menu.
With the menu, the backgroup is erase automatically.
Any way to make it flicking free?
Thanks a lot.

Yes, the view.
In OnRButtonDown I draw the memory graphics(GDI+) and call CView::OnRButtonDown.
I have the same code in CView::OnLButtonDown, it doesn't flick with no context menu.
The framework (generated by BCG app wizard) has such a function:
void CMyView::OnContextMenu(CWnd*, CPoint point)
{
theApp.ShowPopupMenu (IDR_CONTEXT_MENU, point, this);
}

Did you ever solve this?
If not, can you reproduce it in a simple project?

Can anybody tell me the difference between stack & heap? or any relating tutorial.
|
|
|
|
|
|
|
A simple difference is:
1. To declare a variable of size 4G in the stack will usually crash.
struct A {
unsigned char[0xFFFFFFFE];
} obj;
2. To allocate a variable of size 4G in the heap is OK.
A* p = new A;

Hey Max:
(1) There's no hope to compile that code.
(2) 4GB=0x100000000

If you break the problem down, you have the following needs:
1) Audio capture
2) Audio compression
3) Video capture
4) Video compression
5) Transmission of data
6) Audio decompression
7) Audio rendering
8) Video decompression
9) Video rendering
Which part is giving you trouble?

Why do you destroy the dialog, can't you just hide it?

In addition to cpallini's reply...

If the dialog is destroyed, then it needs to be created again.
If you leave the dialog created you could just hide it and show it again
when it's needed.
Either way you need to manage the lifetime of both the CDialog object
and the HWND object it contains.
