I want to develop a program in VC++, that runs in background; i mean that the program has no user interface and runs silently. The motive of this program is that it downloads certain file from internet, and when downloading completes, a dialog box is displayed. I've developed all the core logic and download coding etc. But now i want this program to run as a "silent" application in background.
Can any one tell me how can i convert my application to "invisible" form ????

My program is not necessarily a windows application. I want to run it as a "process" and not "application". Just when you see windows task manager in Win2k, there are two tabs, "applications" and processes". I want to run my program as a process and not as an "application", and this difference is something that i am unable to understand

If not using MFC, then build your app as a "Windows application" (i.e. one having a WinMain entry point) and just do not create any windows at all.
If in MFC, go to the InitInstance of the program, delete the GUI stuff (for dialog-based apps, a few lines of code displaying a modal dialog) and put your code there.

You can create windows but you must not register a class or make any windows visible.

You can simply export the function from your DLL and import it into VB the same way as if you were to call one of the Windows API functions from VB. Then inside that function call you can do just about anything that you would like.

but i want to display the result in vc
how i can do???
or do you hvae any simple code????

It depends on how complicated you wanted to get with the method that you want to display the result.
Inside the function in the C++ DLL, you could simply call MessageBox and display the result. Or you could get more complicated and create a dialog or a window and display more complicated feedback data.
If this is the case though, why not just do it with Visual Basic.
Although I do have one more thought, are you trying to display the output in a console window like a regular console app displays the data?
If you help me understand why you are doing this, or possibly more details in what and how you want to display the data, I may be able to help you out more.
Good Luck

I have an MFC child dialog that I use on an windows CE machine. I would like to place that dialog into another MFC dialog which is skinned when the app is compiled for a non-ce device, ie. the desktop computer. All I need to know is - what is the way one would embed a dialog in another dialog. I have seen how to embed a child dialog into a form view and was also wondering how this compares to doing dialog within dialog. What would be easiest taking in account that I have a skin on the parent dialog.
Cheers,
Clint

Embedding a dialog into a CFormView or another CDialog is basically the same: have the child dialog have no border, and on the OnInitDialog of the parent dialog create the child with suitable parent and position it. There are additional details to fill in, but the basics are simple.

Hi,
I want my program to search if a program is installed or not , from the registry(???).How can i do that(i use MFC)??
|
|
|
|
|
One solution is to check the registry key in the uninstall section. If the registry key is not found, the MFC function should return NULL. Better yet, use a Win32 API registry function including RegOpenKey().
LONG RegOpenKey(HKEY hKey, LPCTSTR lpSubKey, PHKEY phkResult);

Maybe I'm just not good at finding things on MSDN, and my help doesn't list anything in the index about NM_TREEVIEW Anyway, how do I get information from a CTreeCtrl when I handle the CLickTree?
I have:
void CMyDlg::OnClickTree(NMHDR* pNMHDR, LRESULT* pResult)
{
int iRoot = iTheRootOfItemClicked;
int iSub = iSubIndexOfItem;
int iItem = iTheIndexOfTheItem;
}
How do I get that info or am I supposed to do this some other way???
There's honorable mentions of TV_ITEM things and
HTREEITEM, but all I get is:
HTREEITEM Handle to an item in a tree-view control.
Somehow that doesn't help me much.

Try searching on NMTREEVIEW -- this is what I found:
typedef struct tagNMTREEVIEW {
NMHDR hdr;
UINT action;
TVITEM itemOld;
TVITEM itemNew;
POINT ptDrag;
} NMTREEVIEW, FAR *LPNMTREEVIEW;
That's the structure -- you should be able to cast the pNMHDR to a NMTREEVIEW pointer, and then get the struct member of NMTREEVIEW that you want...
Once you get the tvitem you want, use the tvitem.hItem (which is an HTREEITEM) and then use the CTreeCtrl member functions to get the properties of the item you need...
"If at any time I announce that a nation or kingdom is to be uprooted, torn down and destroyed, and if that nation I warned repents of its evil, then I will relent and not inflict on it the disaster I had planned. And if at another time I announce that a nation or kingdom is to be built up and planted, and if it does evil in my sight and does not obey me, then I will reconsider the good I had intended to do for it." -- Jeremiah 18:7-10 (God, commenting on the value of the United Nations)

um, I think this is what I don't know how to do 
Say I have a tree:
- Root1
|
|-- SubRoot1
| |
| |- Item1
| |- Item2 <-- And I click on this one...
| |- Item3
|
|-- SubRoot2
|
|- Item1
|- Item2
How would I be able to say:
You Clicked 1.1.2

NMTREEVIEW* pNMTV = (NMTREEVIEW*)pNMHDR;
HTREEITEM hItemNew = pNMTV->itemNew.hItem;
HTREEITEM hItemsParent = m_wndTree.GetParentItem(hItemNew);
HTREEITEM hItemsParentsParent = m_wndTree.GetParentItem(hItemsParent);
