That code runs ok if executed by an application that runs normally...
but not if executed by an application that runs as a Window
Service.

I've registered an application as a Window Service and I've
started it by the Service Control Manager. In that case the
CreateProcess doesn't let the "child" application to show its window.

Will something like this help:

//Attach foreground window thread
//to our thread
AttachThreadInput(
    GetWindowThreadProcessId(
        ::GetForegroundWindow(),NULL),
    [YourProcessId],TRUE);

//Do our stuff here 
SetForegroundWindow();
SetFocus(); //Just playing safe

//Detach the attached thread
AttachThreadInput(
    GetWindowThreadProcessId(
        ::GetForegroundWindow(),NULL),
    [YourProcessId],FALSE);

Thanks a lot !!!
but.. what's the HWND object that I have to pass to
SetForegroundWindow and SetFocus functions ?
If I've well understood I've to run that code into the
Service that uses the CreateProcess but.. I need an HWND object to pass to that functions....

Yes sorry, I had to go away from my desk, so I fired up the post.
This is a snippet used to bring a dialog on the top of the Z-order, i thought it coudl work in your case. I do not exactely know how a service works, but I assume it is a normal Win application started differently. So I believe you must be able to get a HWND with GetSafeHwnd() from within the service.

The problem is that the service in not a Win application,
it is a simple C++ program with a main, including MFC
functions. So I don't have an HWND object Frown | :(

I think the problem is in STARTUPINFO object settings...

I think the problem is that the service is not interactive. You should make it interactive if it is not already.

this is this.

I think it is a parameter in CreateService():

Message encryption and splitting

Hello

I wanna create a Visual C++ program that encrypt a message and plit the ancrypted message into certain parts,and then the message will be recostructed by a certain amount of parts of the encrypted message.

For the encryption part, simply type encryption in the combo box on the up left of this page (under code project) and you'll find enough article to help you get a start at it.

For the splitting part, I would try and do a search about zip libraries: they used to provide file splitting algorithms.

Bitmap size: LP or DP?

includeh1028-Mar-06 0:51

A bitmap file is in size of 200x100 (pixels).

Now CDC is in MM_LOENGLISH MapMode, If I use ::SetDIBitsToDevice() to print whole bitmap, printed bitmap is very small.

Question:
if Bitmap size is in LOGIC points, the printed image should be in size 2x1 (inches) - but actual printed bitmap is much smaller than that.

so:
is Bitmap size LP or DP?

hint:
DPtoLP changes (200,100) to (33,-17).

CListCtrl SetItem

hi,
I have set the image for a subitem as follows

LVITEM litem;
litem.mask = LVIF_IMAGE;
litem.iSubItem = 1;
litem.iItem = 0;
litem.iImage = 0;
m_List.SetItem( &litem );

but when I try to call the GetItem to get the image associated with a subitem, its not working(it is working if the subitem is 0). I have set the LVS_EX_SUBITEMIMAGES style of the list control. What else should I do..

Please help me

Naveen R ,
I have this problem(But I have derived CListCtrl and I use this way in the NM_CUSTOMDRAW)
anyway I think you can use
int nImage=GetNextItem(-1,LVNI_SELECTED);

I don't think that you can get the index for a sub-item image, since the iImage member of LVITEM structure is specifically described as the index of the item's image, and not the index of the sub-item's image.

Maybe you must manually store the sub-item's image index in the lParam of the item and retrieve it from there.

Best,
Mike

creating a timeout

viperlogic28-Mar-06 0:06

I have a Visual C++6 project for extracting WMI information from machines
across the network. I am using the IWbemLocator::ConnectServer method with the WBEM_FLAG_CONNECT_USE_MAX_WAIT flag. The flag prevents the app from hanging and will timeout the call if not sucuessful after 2mins. But this flag only works for XP pcs and no other like 2000 etc and also is fixed at 2mins.

how can a timeout be implemented so i can kill the ConnectServer method say after 20seconds.

Copy files by network

27-Mar-06 23:44

I’ve been creating C/S application but I’ve been wondering how to install client module direct by network from server module (I don’t want to install it manually).
Main problem is, how to send/copy installation files by network from server module.

It is possible to take advantage with administrative shares i.e.:
Connect to the host (WNetAddConnection2),
Check, if ADMIN$ is available (i.e.: NetShareGetInfo ),
Copy files,
Execute install file or something else to do,
Disconnect (WNetCancelConnection2).

Problem is, when administrative shares are disabled. What can I do then ?

Any ideas ?
