C / C++ / MFC

Hi all!

I am making a program with Win32 API and MSVC++ 2003 that lists running processes on users computer. It works well up to this point but i wanted to add an extra feature. Put a second list box and and filled it with names of processes that i don't want to show in main listbox. like "svchost.exe", "cfosspeed.exe", "spd.exe". I tried this in ListProcesses() function:

   char chhh[260];	//process name; like "calc.exe"
  char tmprr[260];	//process name to be ignored.
  do{
             sprintf(chhh, "%s", pe32.szExeFile);
			 for(int r=0; r<SendMessage(hIgnore, LB_GETCOUNT, 0, 0); r++)
			 {
				 SendMessage(hIgnore, LB_GETTEXT, r,(LPARAM)(LPCTSTR) tmprr); 
				if(!stricmp(chhh, tmprr)){
					found = 1;
				}
				else {
					found = 0;
				}
				}
			if(found==0){
			 LvItem.pszText=chhh; 
			 LvItem.iSubItem=0;       
			 ListView_InsertItem(hList, &LvItem);
			 LvItem.iSubItem=1;       
			 LvItem.pszText="0"; 
			 ListView_SetItem(hList, &LvItem);
}
			 
  } while( Process32Next( hProcessSnap, &pe32 ) );

But it doesn't work. I tried to put for example "cfosspeed.exe" instead of tmprr, it ignored successfully.

by the way, hIgnore is hwnd of ignore list box.

Thanks!

I think you should reconsider your for loop like this:

bool found = false;
for( int r = 0; . . . )
{
    SendMessage(hIgnore, LB_GETTEXT, r, (LPARAM)tmprr);
    if( stricmp(chhh, tmprr) == 0)
    {
        found = true;
        break;
    }
}

if( ! found) . . .

I hope this helps.

I Suggest you to use LB_FINDSTRING

I think you can sort out the issue, if you debug the application.

One thing I noticed is that, you two times you are modifying teh iSubItems(the final value is 1).
In MSDN it's clearly saying that,

You cannot use ListView_InsertItem or LVM_INSERTITEM to insert subitems. The iSubItem member of the LVITEM structure must be zero

I removed LvItem.iSubItem=0; line but the list couldn't be populated.

Sarath C5-Jul-06 2:27

I think the subitem should be zero.

I'm not getting anything more from the code.
check the following too.

1. Check GetLastError(); (put @err in the watch window while debuging to avoid coding).
2. If possoble use MFC

I trying to ignore "svchost.exe" but almost every process in main list gets ignored. Any suggestions?

I think you should post your changed code.

You're right.

   char chhh[260];	//process name; like "calc.exe"
  char tmprr[260];	//process name to be ignored.
  bool found = false;
  do{
             sprintf(chhh, "%s", pe32.szExeFile);
			 for(int r=0; r<SendMessage(hIgnore, LB_GETCOUNT, 0, 0); r++)
			 {
				 SendMessage(hIgnore, LB_GETTEXT, r,(LPARAM)(LPCTSTR) tmprr); 
				if( stricmp(chhh, tmprr) == 0){
					 found = true;
					break;
				}
				}
			if(!found){
			 LvItem.pszText=chhh; 
			 LvItem.iSubItem=0;       
			 ListView_InsertItem(hList, &LvItem);
			 LvItem.iSubItem=1;       
			 LvItem.pszText="0"; 
			 ListView_SetItem(hList, &LvItem);
			
}

Since you moved the declaration of bool found = false;, you have to initialize it before for:

bool found;
do
{
    . . .
    found = false;
    for( int r = 0; . . .)
    {
        . . .
    }
    . . .

Right click on the property window. Go to border . There you can modify the border style of the dialog. A dialog has a border of type Dialog Frame by default in an MFC dialog based Application.

Somethings seem HARD to do, until we know how to do them.

how to change the colour of the text in edit control in win32 application

add a WM_CTLCOLOR handler either in the dialog box
or
Add the same in a class which is derived from the CEdit. (Subclass or create a control variable of your edit box to this class)
see the following code snippet

HBRUSH CSampleDialogDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
	HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

	if (CTLCOLOR_EDIT == nCtlColor)
	{
		pDC->SetTextColor(RGB(0xFF,0,0));
	}
	return hbr;
}

Note that, if you are trying the above code in a dialog, will replace color of all edit boxes in the dialog.

See MSDN to know more about WM_CTLCOLOR message

add Onctl function and add following code
HBRUSH hbr;
//HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

if(nCtlColor == CTLCOLOR_STATIC )
{
hbr=CreateSolidBrush(RGB(0,100,0));
pDC->SetTextColor(RGB(0,0,255));
pDC->SetBkColor(RGB(0,100,0));
//for text colour, also use this: pDC->SetTextColor(RGB(0,0,0));
}
else
{
if(nCtlColor == CTLCOLOR_BTN)
{
hbr=CreateSolidBrush(RGB(0,100,0));
pDC->SetTextColor(RGB(0,0,1));
pDC->SetBkColor(RGB(0,100,0));
// pDC->SetBkColor(TRANSPARENT);
// for text colour, also use this: pDC->SetTextColor(RGB(0,0,0));
}
// hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
}
return hbr;
