Hi all,
We have a class CBitmapButton which is derived from cButton. We need to enable the tool tip for this class. We have written the code for the same.
We have followed all the steps required to enable a tool tip for this button. However we are facing a problem while displaying the tool tip. The tool tip is seen at first when the mouse is moved to this button. If we hold the mouse on that button, after some time, the tool tip vanishes and then the tool tip is never seen even if the mouse is moved to the next button and brought back to this button .
Please suggest some solution to the above problem.
Any kind of help would be appreciated.
Thanks
amit

Hi all,
Thanks for the help. I tried the following things one by one and checked the output
1. Capture the mouse event and used TrackMouseEvent
2. Called InitToolTip function in PreTranslate before RelayEvent
3. Set the flag to TTF_SUBCLASS while creating the tool tip control.
However, I am still not getting the tool tip after the time out.
I shall post my code in a short while. Please look at it and let me know what is wrong in it
Thanks again for the help provided.
Regards,
amit

Given below are the steps for enabling the tool tip for the CBitmapButton
1. The class CTipBitmapButton is derived from CButton. This has teh owner's draw property set to TRUE.
2. An object of CToolTipCtrl m_ToolTipCtrl is created.
3. m_ToolTipCtrl is initialised in the constructor
4. The tool tip is initialised by using following code:
m_ToolTipCtrl = new CToolTipCtrl;
m_ToolTipCtrl->Create(this);
m_ToolTipCtrl->Activate(TRUE);
m_ToolTipCtrl->SetFont(GetFont(), FALSE);
5. New function DisplayToolTip is called in the DrawItem function of the class CTipBitmapButton
6. The function DisplayToolTip has the following code
a. Delete the tool tip if it exists
b. Set the tool tip using SetToolTipText function
c. Set the delay time to TTDT-INITIAL
7. The function SetToolTipText has the following code
a. Initialise the tool tip
b. If the tooltip tool count is 0, then m_ToolTipCtrl->AddTool(this, rect, 1)
c. m_ToolTipCtrl->UpdateTipText(tooltext,this,1)
d. m_ToolTipCtrl->Activate(TRUE);
8. In PreTranslateMessage
m_ToolTipCtrl->RelayEvent(pMsg);
With this code, the tool tip does not come after the time out. Please suggest.
Any kind of help would be appreciated.
Thanks,
amit

If you are manually passing mouse movement messages to the tooltip, be sure that you are doing it from the parent window of the CBitmapButton, and not from the button control itself, or use _TrackMouseEvent(...) to indicate to the tooltip control when you have moved off of the button (send it a POP message).
My guess is that the tooltip is not getting messages when you move off of the control, so it still thinks the mouse is over the button (standing still), and will not reset its state to display itself again.
Alternately, you could use a little-known (or little-used) feature of the ToolTip control, the TTF_SUBCLASS flag when creating the tooltip to implement "fire-and-forget" tooltip support, where you do not have to handle passing messages around.
Peace!

how can i monitor all register sub keys in the selected root regiter key.
and display the register key name,value ans status in list control.
how can i do it?

You can use :
char lszValue[255];
CString str ;
HKEY hKey;
LONG returnStatus;
DWORD dwType=REG_SZ;
DWORD dwSize=255;
returnStatus = RegOpenKeyEx(HKEY_LOCAL_MACHINE, "Key path separeted by \\", 0L, KEY_ALL_ACCESS, &hKey);
if (returnStatus == ERROR_SUCCESS)
{
returnStatus = RegQueryValueEx(hKey,"value you want to read", NULL, &dwType,(LPBYTE)&lszValue, &dwSize);
if(returnStatus == ERROR_SUCCESS)
{
str = (LPCTSTR)lszValue;
}
}
RegCloseKey(hKey);
Cheers

By using RegNotifyChangeKeyValue().

This is normal behavior with VS v6. Has that changed with VS 2005?

I build a dialog based MFC program.
in the file "StdAfx.h" I add the following code,which is used to define a global variable of type CString.
#ifndef jjjjjjjjjjjjjjjjjjj
#define jjjjjjjjjjjjjjjjjjj
CString StrGlobal;
#endif
and then I use it in another file "newfile.cpp"
#include "stdafx.h"
extern CString StrGlobal;
void fun()
{
StrGlobal = _T("KDKDK");
}
when I build the program, following link error shows up:
Linking...
StdAfx.obj : error LNK2005: "class CString StrGlobal" (?StrGlobal@@3VCString@@A) already defined in newfile.obj
why dose this happen? and how can I fix it ?
Thank you very much!!!

You've got the extern in the wrong file: It should be in the .h file.

move the declaration
CString StrGlobal; to stdafx.cpp or make the varaiable static

yes, I make it static and it works. thank you so much.
but ,could you please explain to me briefly the reason?

The .h file might have been include by multiple cpp file. so while compiling , the variable will be present in the vtable of obj file corresponding to each cpp. so while linking, linker will find multiple object and generates the error since it dosen't know to which obj it have to link.

For backup purpose Windows OS makes an Emergency Repair Disc(ERD) through Windows Backup Utility.In That
it makes a folder named RegBack, where it copies all registry values to files. I want to do the exactly same in my
program through VC++. Can anybody give me some direction please.I need help
nirmal

Hi
you can use the shellExecute for invoking the backup process from your VC++ apllication.
For windows Xp: you can call ShellExecute on rstrui.exe
For Windows 2000: you can call ShellExecute on ntbackup.exe
