you can use
hProcess = OpenProcess (PROCESS_QUERY_INFORMATION|PROCESS_VM_READ, FALSE, yourID);
openprocess/EnumProcessModules/GetModuleFileNameEx/
First you should Handle to process and then you can use this function
and other functions....

Hi, if you already know the ProcessID you can use EnumProcesses function, instead of OpenProcess - it will tell you if the specified process is running. Good Luck!

Hi all,
I set the color of combobox text in OnCtlColor. But I cannot set the color for disabled combobox text. It always comes as gray always.
How can I change the text color of disabled combobox?
Thank you.

This cannot be set through OnCtlColor . Subclass the combo for customized functionality.

Thank you for your replay.
How can I do that? Can you give me a little bit explanation?
I am confused, about where should we write the code to set the color?

Just a sample...
HBRUSH CSuperComboBox::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
if (nCtlColor == CTLCOLOR_EDIT)
{
if (m_edit.GetSafeHwnd() == NULL)
m_edit.SubclassWindow(pWnd->GetSafeHwnd());
}
else if (nCtlColor == CTLCOLOR_LISTBOX)
{
if (m_listbox.GetSafeHwnd() == NULL)
m_listbox.SubclassWindow(pWnd->GetSafeHwnd());
}
HBRUSH hbr = CComboBox::OnCtlColor(pDC, pWnd, nCtlColor);
return hbr;
}
void CSuperComboBox::OnDestroy()
{
if (m_edit.GetSafeHwnd() != NULL)
m_edit.UnsubclassWindow();
if (m_listbox.GetSafeHwnd() != NULL)
m_listbox.UnsubclassWindow();
CComboBox::OnDestroy();
}

Hi all,
I'd like to change the icon of the child window dynamically. When I open a new window each time, I should be able to see the child window with different icon.
Using SetIcon in child window's PreCreateWindow function, I am able to set the icon; but with assertion failure.
Kindly suggest me a solution.
Thanks in advance,
Sarvan AL

Pass different icons to the child window everytime. And use SetIcon to display it.

Thanks Nibu,

Do you have any other ideas to achieve this?
Thanks Once again,

Click on retry. Debug and find where it's asserting.

Hi Nibu,
This is my code snippet.
BOOL CChildFrame::PreCreateWindow(CREATESTRUCT& cs)
{
if( !CMDIChildWnd::PreCreateWindow(cs) )
return FALSE;
SetIcon(m_hIcon, FALSE) ;
return TRUE;
}
m_hIcon is CChildFrame's member and I load the icon in the constructor, as follows:
m_hIcon = LoadIcon(AfxGetInstanceHandle(),
MAKEINTRESOURCE(ICON_TEST)) ;
What is wrong with this?
|
|
|
|
|
Yeah, I got it.
I moved the code "SetIcon(..)" into OnPaint(). Now it works.
Thanks a lot Nibu.

something tells me something is wrong
you must be getting Assertion failures cause the target window is not created yet.

You are using OnPaint for the wrong reasons.

Move this to OnCreate . If you use it here it will assert because the window handle is not created. It is just in PreCreateWindow stage.

MFC doesn't have any functions to handle webcam either you are using DirectX or some third party SDK for this, please specify or paste some code.

Hi All,
I have a small problem with the code snippet below. Can anyone help me out in this. I launched Internet Explorer as a process from my application. I closed the Internet Explorer using the close button and when I use the following code of "OpenProcess", the method still works(meaning that the method is able to the open the process with the specified ID.
HANDLE p = OpenProcess(PROCESS_ALL_ACCESS, FALSE, dwProcessIdentifier);
if(p != NULL)
MessageBox(_T("Please check patient context"),_T("EDMS context change"),MB_OK);
can anyone give some info on this please.
|

Please try the below method
HANDLE p = OpenProcess(PROCESS_ALL_ACCESS, FALSE, dwProcessIdentifier);
DWORD dwEitCode = 0;
if( 0 != hProcess)
{
GetExitCodeProcess( p,&dwEitCode );
if( ( STILL_ACTIVE == dwEitCode )
{
// process is alive
}
else
{
// process is dead
}
Closehandle( p )
}

Thanks Naveen. Its working as expected.
Could you please tell me what was wrong with my code that I used. I had also checked for NULL of that Handle returned right?
|
|
|
|
|
I too don't know.
But just think.. if OpenProcess return NULL if the process dosen't exists, what's the significants of GetExitCodeProcess() api..
I too was facing the same problem some months back.
