The code snippet indicates that some assumptions may not be valid:

1. Does the child program run? Save the result of the WinExec call in
a variable and check it. Add a positive statement that the program was run properly,

2. Does the child program read the command line correctly? You need postive and negative results here too.

3. Can the child process find the input file? WinExec may be able to locate the program to run but the program may not be able to locate the input file. Pay attention to the current directory and how WinExec finds the child program.

My guess is that #3 is the problem since you can run the child program
independently.

Putting values in array

I have two methods.. OnCheck() which will check the record in listview control and another method Onchecklist() which will disabel or enable the buttons. Now my query is I want to check more than 1 record in the listview controls and store the indexes in an array. Then I want to pass each one to the OnCheckEPayList() method.
Any pointers would be greatly helpful.

Thanks,
Sai

Your question isn't clear at all. What are you trying to do exactly ? Please, think that we do not see your code and so we have no idead at all what OnCheck Onchecklist are doing, which buttons you are talking about and what you store in the listview.

Anyway, it seems you are looking for a container class. Did you have a look at std::vector (or std::list) ?

Are you wanting to know which items in the list control are selected? If so, use the GetSelectedCount() and GetNextItem(..., LVNI_SELECTED) methods.

if you are using a CListBox, have a look at GetSelItems, but your list but be set to use multiselect (and/or extended select) style.

if you are using a CListCtrl use CListCtrl::GetSelectedCount and CListCtrl::GetNextItem ( see this[^] )

hi,

for my one of application, i installed diffrent printer model through printer Drivers INF file, My application works fine.

Now i needed that when i'm parsing INF file through my program, how can i sure that pertincular printer model is PnP capable or not. is there any standerd way to decide this when reading a INF file. for example for an INF file the [ModelSection] defined as:

/////////////////////////////////////////////////////////////

; Model sections
;
; Each section here corresponds with an entry listed in the
; [Manufacturer] section, above. The models will be displayed in the order
; that they appear in the INF file.

How to find Child Window of another Application?

narayanagvs5-Dec-07 23:50

narayanagvs

5-Dec-07 23:50

Hi,

I need to get a handle to the "Save As" Dialog of another
application once the user Clicks "Save As" Option in that
application.So as to kill the dialog Immediately.

I used FindWindowEx and EnumChildWindows but no use.
Using Spy++ I tried to get the class name of the "Save As"
Dialog it shows "#32770 (Dialog)" as is for any dialog box.

HWND hWnd = ::FindWindowEx(st_hwnd,NULL,
(LPCWSTR)"#32770 (Dialog)",(LPCWSTR)"Save As");

Even if "Save As" Dialog is not the immediate child window
for FindWindowEx to work,it should work with
EnumChildWindows,but doesn't.

HWND hWndChild = NULL;
EnumChildWindows(pWndWmp->m_hWnd, EnumAppearanceChildProc, (LPARAM)&hWndChild);		

BOOL CALLBACK EnumAppearanceChildProc(HWND hwnd, LPARAM lParam)
{									
        CString str = _T("");
	CWnd *pChildWnd = CWnd::FromHandle(hwnd);
	pChildWnd->GetWindowTextW(str);			
	if(_tcscmp(str,_T("Save")) == 0)	
	{					
		*reinterpret_cast<hwnd*>(lParam) = hwnd;	
		return FALSE;	
	}		
	return TRUE;
}</hwnd*>

What could be the problem? Is there a way where I can
get the handle to the "Save As" dialog of another application?

Thanks
Satya

When begin dragging, them dragging image will offset twards left and up a little to the original one. I'd like the two images (original and dragging) in the same rect at the very begining. Here is the code:

void CDragDropListCtrl::OnBegindrag(NMHDR* pNMHDR, LRESULT* pResult) 
{
	NM_LISTVIEW *pNMListView = (NM_LISTVIEW*)pNMHDR;
	// TODO: Add your control notification handler code here
	SetCapture();
	CImageList *pIL=GetImageList(LVSIL_NORMAL);
	CRect rt;
	GetItemRect(pNMListView->iItem,&rt,LVIR_ICON);
	CPoint pt;
	GetCursorPos(&pt);
	ScreenToClient(&pt);
	pt.x-=rt.left;
	pt.y-=rt.top;
	pIL->BeginDrag(pNMListView->iItem,pt);
	ClientToScreen(&rt);
	pIL->DragEnter(NULL,rt.TopLeft());
	m_Dragging=TRUE;
	*pResult = 0;
}
