want to monitor the changes in the registry,By selecting on of the Root key then monitor the changes in that inlcude key,subkeys.....for name,value and status.
i Add the code in the thread function for monitoring as belowvoid MonitorThread(void* pParam)
{
//here am not understanding what event it returns
// RegNotifyChangeKeyValue(hKey1,TRUE,REG_NOTIFY_CHANGE_NAME|
// REG_NOTIFY_CHANGE_ATTRIBUTES|REG_NOTIFY_CHANGE_LAST_SET,hEvent1,TRUE);
DWORD dwFilter = REG_NOTIFY_CHANGE_LAST_SET, dwType, dwSize ;
char lpszUser[81];
HANDLE hEvent;
HKEY hKey;
LONG lErrorCode;
while(1) {
m_Sec.Lock();
//memset(lpszUser,0,81);
dwSize = 81;
dwType = REG_SZ;
// Open a key. Change second parameter to fit your needs.
lErrorCode = RegOpenKeyEx(hKey, NULL, 0,
KEY_NOTIFY | KEY_READ, &hKey);
// Create an event.
hEvent = CreateEvent(NULL, TRUE, FALSE, NULL);
// Watch the registry key for a change of value.
lErrorCode = RegNotifyChangeKeyValue(hKey, TRUE, dwFilter, hEvent,TRUE);
// Wait for an event to occur.
WaitForSingleObject(hEvent, INFINITE);
lErrorCode = RegQueryValueEx(hKey,NULL,0,&dwType,(unsigned char*)lpszUser,&dwSize);
//Add code for reading from the registry key
int item=pList->InsertItem(pList->GetItemCount(),lpszUser);
// Close the key.
lErrorCode = RegCloseKey(hKey);
m_Sec.Lock();
// Close the handle.
CloseHandle(hEvent);
// if(m_cStop1==TRUE)
// exit(0);
//Sleep(1);
}
}
For reading root key i put one combo box in the dialog and selecting one root key by pressing start button starts the monitoring ,if any changes occurs in the that rootkey registry display that key name,value ans status(create/modify/delete).
by pressing stop button stops the monitoring
Thanks,
Kiran.V

If this code is in a secondary thread, then the following statement is a recipe for failure:
int item=pList->InsertItem(pList->GetItemCount(),lpszUser); Instead you should be posting a message to the main thread (the one that owns the GUI). See here for why.

How to make the edit display the value by hex string?
such as
....
m_spin.SetBase(16);
m_spin.SetRange(0,0xFF);
m_spin.SetPos(0x2F);
...
the edit display "0x002F",what I want is just the string "2F" only.
ps:I tried to format m_edit in the function OnUpdateEdit(), but failed.

|
|
|
What is this m_spin ? A Progress bar ?
It has nothing to do with the edit control !
What you put in the edit control, it's up to you to format it correctly.

It may be an object of CSpinButtonCtrl..
nave
|
|
|
|
|
yes
CSpinButtonCtrl m_spin;
CEdit m_edit;
..
m_spin.SetBuddy(&m_edit)
...
|
|
|
|
|
 yes
CSpinButtonCtrl m_spin;
CEdit m_edit;
..
m_spin.SetBuddy(&m_edit)
...

If "2F" is already in s string-type variable, just use CEdit::SetWindowText():
m_edit.SetWindowText("2F");If not, please explain more clearly what you are after.

In fact, I want to build a simple tool to debug some registers. the registers value range is from "0x00" to "0xFF". only display the string from the hex value
please see sketch map below:
____
|DE | // edit value display is 00,01,02.......,0A,0B,....0F,...1E...FF
<||> // spin left<- ->right
|
|
|
|
|
Now I understand. Unfortunately, the only solution I can think of is to make the edit control right-justified and just wide enough to hold FF.

what you mean is this function m_edit.SetWindowsText("FF")?
would you tell me the way of you setting?
thank you

I assumed you simply wanted to know how to set the text of an edit control.

yes, it is also a problem for me.
how to set the text/string of edit control that display the value from "00" to "FF"?
|
|
|
|

Why don't you set it through code?
Remove the style UDS_SETBUDDYINT.
Handle the notification for spin control.
Now get the current integer value of the spin control and get it in hex format using Format function of CString or by using sprintf.
for ex:
sprintf(buf, "%x", spinVal);

thank you very much for your suggestion,
I removed the style UDS_SETBUDDYINT, and added the code below.
void CFlexgridDlg::OnDeltaposSpin1(NMHDR* pNMHDR, LRESULT* pResult)
{
NM_UPDOWN* pNMUpDown = (NM_UPDOWN*)pNMHDR;
// TODO: Add your control notification handler code here
BYTE str;
str = m_UpDown.GetPos();
m_edit.Format("%02x",str);
m_edit.MakeUpper();
UpdateData(false);
*pResult = 0;
}
the text of the edit display the hex string I want now.
but I met another problem is if how to limit input value from keyboard of the edit is hex string format.
CEdit m_edit1Ctrl;
CString m_edit;
void CFlexgridDlg::OnChangeEdit1()
{
// TODO: If this is a RICHEDIT control, the control will not
// send this notification unless you override the CDialog::OnInitDialog()
// function and call CRichEditCtrl().SetEventMask()
// with the ENM_CHANGE flag ORed into the mask.
// TODO: Add your control notification handler code here
char chartemp;
char edit1sel;
UpdateData(TRUE);
edit1sel = m_edit1Ctrl.GetSel();
if(edit1sel)
chartemp = m_edit.GetAt(edit1sel-1);
else
chartemp = 0x00;
if(!(isxdigit(chartemp)))
{
m_12.SetSel(edit1sel-1,edit1sel);
m_12.Clear();
}
UpdateData(false);
}
the code can work well while the edit is not a buddy of the spin, if set edit as a buddy of the spin. the error occurs, UpdateData() cann't work here?

Subclass CEdit and handle WM_CHAR.
Check for valid hex characters.
If not valid hex characters eat the message else display char.
