I already said this to you once. ICopyHook is not going to help you. You need a file system filter driver for your needs. Now, I'll wait for you to come tomorrow and post the SAME THING again.

Sir plz try to understand my problem..I follow member advice.
I know you told me that use file system filter driver. But i havn't found any example of file system filter driver.So i find alternative option.If you have any example of file system filter driver then plz give me

Drivers are an advanced subject. Perhaps you should work your way up to that level.

This function makes two assumptions: 1) the shell is used for the copy operation, 2) only folders or printer objects will be copied. The OP clearly wants to copy files too, and he may want to do such using more than just the shell.

I think you are interested in getting some notifications when some changes happens in the file system.
Just have a look at the pair of win32 APIs FindFirstChangeNotification and FindNextNotification.
A sample program is available at http://msdn.microsoft.com/en-us/library/aa365261(VS.85).aspx[^]

Are you wanting this second copy to take the place of the first copy, or do you want it to happen in addition to?

Hi all,
I have one query. I am able to run any .exe using createProcess() by giving the complete path of exe as first parameter.
If I want to run diskmgmt.msc then I click on Start->run-> "type here diskmgmt.msc". Now I want to execute this disk management by using createprocess method.
Please suggest me that how can I do this?
Thanks.

The process for running msc files is C:\WINDOWS\system32\mmc.exe.
So for e.g. you wanna run an msc file called perfmon.msc then you've got to pass it on as a command line argument...
C:\WINDOWS\system32\mmc.exe perfmon.msc
So for disk management msc file we'll go like this...
C:\WINDOWS\system32\mmc.exe diskmgmt.msc
Another option is to use ShellExecuteEx without worrying about which exe should be used for opening a file. The Shell will decide. But limitations being that you cannot wait on the process handle.

mmc.exe (Microsoft Management Console) is the host executable that actually runs when you open diskmgmt.msc. So spawn mmc.exe by using CreateProcess(). For instance,
STARTUPINFO si;
ZeroMemory( &si, sizeof(si) );
si.cb = sizeof(si);
PROCESS_INFORMATION pi;
ZeroMemory( &pi, sizeof(pi) );
CreateProcess( NULL,
_T("mmc.exe diskmgmt.msc"),
NULL,
NULL,
FALSE,
0,
NULL,
NULL,
&si,
&pi );
Well, If you just want to open the DiskManagementConsole, then ShellExecute() can do it more easily.
ShellExecute( 0, _T("open"), _T("diskmgmt.msc"), 0, 0, SW_SHOW );

Jijo.

Why repost? Asking in the same thread will get you more polite answers?
BTW adding debug information to your release builds will help, then check in debugger to see which variable is NULL.

Hello,
I am trying to change the Back Ground color of highlight when a text is selected in Rich edit control to Yellow color.
The problem is it does not leave the default Black color and mixes the Yellow with Black to generate a Highlight of Blue instead of yellow.
Mentioned below is the code:
void CEditSubClass::OnChange()
{
// TODO: If this is a RICHEDIT control, the control will not
// send this notification unless you override the CEdit::OnInitDialog()
// function and call CRichEditCtrl().SetEventMask()
// with the ENM_CHANGE flag ORed into the mask.
// TODO: Add your control notification handler code here
CString strText;
int nLengthofString , i;
this->GetWindowText(strText);
nLengthofString = this->GetWindowTextLength();
//get pointer to htmlsourcebar
CMainFrame* pWnd = (CMainFrame*)(AfxGetMainWnd());
ASSERT_VALID(pWnd);
CHtmlSourceView* pHtmlView = pWnd->GetHtmlSourceBar();
CString m_txtHtmlViewSourceUpper;
//populate the FINDTEXTEX structure
FINDTEXTEX ft;
ft.chrg.cpMin = 0;
ft.chrg.cpMax = -1;
ft.lpstrText = (LPSTR) LPCTSTR(strText);
//find text
i = pHtmlView->m_ctlHtmlViewSource.FindText(FR_DOWN,&ft);
COLORREF crBkYellow = RGB(255,255,0);
CHARFORMAT2 fmt;
::memset(&fmt,0,sizeof(fmt));
fmt.cbSize = sizeof(fmt);
fmt.dwMask = CFM_BACKCOLOR;
fmt.dwEffects = 0;
fmt.crBackColor = crBkYellow;
long lResult = ::SendMessage(pHtmlView->m_ctlHtmlViewSource.GetSafeHwnd(), EM_SETCHARFORMAT, (WPARAM)SCF_SELECTION, (LPARAM)&fmt);
//set the selection
pHtmlView->m_ctlHtmlViewSource.SetSel(i,i+nLengthofString);
pHtmlView->m_ctlHtmlViewSource.HideSelection(FALSE,TRUE);
}
I would be thankful to some one who can help me out.

Hello everyone,
My question is about how many instances' copies are made when inserting new elements into map. Here is my code and questions.
1.
I think when not using pair, there will be one instance copied, from string instance named MikeName to the int key "1" related string instance in the map, and map maintains a separate indepenent copy of string instance from MikeName other than just making a reference to DavidName?
2.
And using pair will make one additional instance copy, from from string instance named MikeName to pair (pair will maintain a separate instance other than just making a reference), and from pair to string instance in the map.
#include <string>
#include <iostream>
#include <map>
#include <utility>
using namespace std;
int main()
{
string MikeName = "Mike";
string DavidName = "David";
map<int, string> Employees;
Employees[1] = MikeName;
pair<int, string> p(2, DavidName);
Employees.insert(p);
return 0;
}
thanks in advance,
George

You can simply test this by putting a simple custom class into a map that has a copy constructor and an assignment operator and keep a counter as a member.
Increment the counter in copy constructor/assignment operator. "Also don't forget to copy or assign the counter else you will lose the counter value." Print out this counter to check counter value. You can give an instance a unique name to differentiate between different instances. May be write a small test app!
Or else you can debug through and find.

Thanks Nibu,
I found using pair there will be an additional copy -- and my further question is why should we use pair? In what situations should it have more benefits?
regards,
George

It's a long story, and this[^] is one such story.
BTW IMO googling on these questions will help you more, instead of waiting 3 hours for someone to answer your queries.

Thanks Nibu,
I have taken one hour to do reading for the great document you referred. But from the document, there is no conclusion what is the special benefits of using pair. Do you have any ideas or comments?

George

Some stl containers do take/return a pair object, that's one of the reason why I would use a pair.

Exactly that's why I said it's a long story.

It means we have to use it...
Any way, could you list your reaons (besides the above one) why and when using pair has special benefits please?

From MSDN:
The two most common uses for a pair are as return types for functions that return two values and as elements for the associative container classes map Class and multimap Class that have both a key and a value type associated with each element. The latter satisfies the requirements for a pair associative container and has a value type of the form pair<const mapped_type="">.
