You can use of a Derived CStatic and use of it for show image then you can declare WM_LBUTTONDOWN,WM_LBUTTONUP and other messages for it also we have a class on the MFC CBitmapButton Class .

I tried searching this up on Google but I couldn't find anything. Is there any way to prevent a process from showing up under the processes tab in Windows Task Manager, or is it possible to not allow the termination of a process? I've tried something like this already:

::SendMessage(hWnd,LVM_DELETEITEM,(WPARAM)23,0);

Where hWnd is the HWND of the Task Manager window, but what happens is that the list refreshes every half second (I think) and deleting a process once won't work. Deleting it multiple times within 500 milliseconds results in process #24, 25, 26, etc. being deleted. And what's worse, there is NO way I can get the location of my app's process in the listbox. I don't know if it's the 1st process displayed or the last one, or somewhere in between.

So, is there ANY way to not allow a user to terminate a process, or to make an "invisible" process?

Thanks in advance. Smile | :)

I think some times ago some people on this forum have this question and also if you search on the codeproject (I think I saw on the codeproject not sure) you can find an article that it hide process of Task Manager but you can hide your process of Task Manager but if some one use of other programs he/she can sees your process?

Why can't you trap TerminateProcess?[^]

How to insert data into ListBox(Something Different)

Re: How to insert data into ListBox(Something Different)

28-Oct-07 19:09

Hi All,

I am using Win32 Application. In that I have created resource as Dialog and also in this Dialog I have added onr ListBox control. Now I want to insert data in to this Dialog.

In this I have added one C++ class in which I am using like below to open Dialog.....

<br />
void CCurrentWnd::Open()<br />
{<br />
	DialogBoxParam(hAppInstance,MAKEINTRESOURCE(IDD_CURWND),NULL,(DLGPROC)CurrntWndDlgProc,(LONG)this);<br />
}<br />

As shown in above code my CurrentDlgProc is shown as below....

<br />
<br />
BOOL CCurrentWnd::CurrntWndDlgProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)<br />
{<br />
	CCurrentWnd * _this = (CCurrentWnd *)GetWindowLong(hwnd,GWL_USERDATA);<br />
	switch(uMsg)<br />
	{<br />
<br />
	case WM_INITDIALOG:<br />
		{<br />
                      HWND m_list1;<br />
<br />
                      m_list1 = GetDlgItem(hwnd,IDC_WNDLIST);<br />
                                           <br />
                      //Now here I got the handle of the ListBox<br />
                      // Now How to insert data in <br />
                      //this ListBox from here within this class.<br />
                 }<br />
                            <br />
<br />
                 //Any code                          <br />
          }<br />
}<br />
                                         <br />

Here IDC_WNDLIST is the ID of the ListBox control.
Is there any method for ListBox control as in Tab control like TabCtrl_InsertItem().?

If you know any other alternative then plz reply me.

Thanks in Advance.

Hi,,

I got little much problem with same.I am using SendMessage() function to set the value for the ListBox using LB_ADDSTRING message.
But I got not perfect value as pass here in the parameter lParam of Sendmessage() function.

I am passing such like this.

<br />
char *str ="Desktop";<br />
SendMessage(m_list1,LB_ADDSTRING,NULL,(LPARAM)(str));<br />

And I got undefined value in listbox like square rectangles.

If you have any other way to pass then tell me.

Thanks.

::SendMessage(GetDlgItem(IDC_LIST1)->m_hWnd,LB_ADDSTRING,0,(LPARAM)(str));

You can just put a progressbar in dialog through resource editor.

In the OnInitDialog set a timer and in the OnTimer you can call StepIt api of the progressbar.

Hello All,

I am using one variable of type BYTE *

Now i want to allocate memory to it but at runtime.

The problem is that size will not remain fixed after intitalization, it may increase as i want to store element in it.

I had used malloc, GlobalAlloc , but it want work because it require size of memory to me initialize.

but i need when i am inserting an element to the variable then it shuld increase size by one?

Thanks in advance.

Can you use CArray ?
The CArray class supports arrays that are are similar to C arrays, but can dynamically shrink and grow as necessary.

Regards,

std::list sounds like a good choice since elements won't move in memory once they're in the list.

Sounds like you could use std::vector.
A vector is guaranteed to be in one continouus memory chunk, and you can get the address (which may change when adding items!) as the adress of its first item.
That is for std::vector<BYTE> vec by calling &vec[0].

Let's think the unthinkable, let's do the undoable, let's prepare to grapple with the ineffable itself, and see if we may not eff it after all.
