If you are using ShellExecute, then can't you use the special flags to open 
the application minimised, while keeping the current app active 
(SW_SHOWMINNOACTIVE). Here is the help snippet for ShellExecute :-

The ShellExecute function opens or prints a specified file. The file can be an 
executable file or a document file. See ShellExecuteEx also.

HINSTANCE ShellExecute(

     HWND hwnd,	// handle to parent window
     LPCTSTR lpOperation,	// pointer to string that specifies operation to perform
     LPCTSTR lpFile,	// pointer to filename or folder name string
     LPCTSTR lpParameters,	// pointer to string that specifies executable-file 
parameters
     LPCTSTR lpDirectory,	// pointer to string that specifies default directory
     INT nShowCmd 	// whether file is shown when opened
    );	


Parameters

hwnd

Specifies a parent window. This window receives any message boxes that an 
application produces. For example, an application may report an error by 
producing a message box.

lpOperation

Pointer to a null-terminated string that specifies the operation to perform. 
The following operation strings are valid:

String	Meaning
"open"	The function opens the file specified by lpFile. The file can be an 
executable file or a document file. The file can be a folder to open.
"print"	The function prints the file specified by lpFile. The file should be a 
document file. If the file is an executable file, the function opens the file, 
as if "open" had been specified.
"explore"	The function explores the folder specified by lpFile.


The lpOperation parameter can be NULL. In that case, the function opens the 
file specified by lpFile.

lpFile

Pointer to a null-terminated string that specifies the file to open or print 
or the folder to open or explore. The function can open an executable file or 
a document file. The function can print a document file.

lpParameters

If lpFile specifies an executable file, lpParameters is a pointer to a 
null-terminated string that specifies parameters to be passed to the application.
If lpFile specifies a document file, lpParameters should be NULL.

lpDirectory

Pointer to a null-terminated string that specifies the default directory.

nShowCmd

If lpFile specifies an executable file, nShowCmd specifies how the application 
is to be shown when it is opened.  This parameter can be one of the following 
values:

Value	Meaning
SW_HIDE	Hides the window and activates another window.
SW_MAXIMIZE	Maximizes the specified window.
SW_MINIMIZE	Minimizes the specified window and activates the next top-level 
window in the Z order.
SW_RESTORE	Activates and displays the window. If the window is minimized or 
maximized, Windows restores it to its original size and position. An 
application should specify this flag when restoring a minimized window.
SW_SHOW	Activates the window and displays it in its current size and position.
SW_SHOWDEFAULT	Sets the show state based on the SW_ flag specified in the 
STARTUPINFO structure passed to the CreateProcess function by the program that 
started the application. An application should call ShowWindow with this flag 
to set the initial show state of its main window.
SW_SHOWMAXIMIZED	Activates the window and displays it as a maximized window.
SW_SHOWMINIMIZED	Activates the window and displays it as a minimized window.
SW_SHOWMINNOACTIVE	Displays the window as a minimized window. The active 
window remains active.
SW_SHOWNA	Displays the window in its current state. The active window remains 
active.
SW_SHOWNOACTIVATE	Displays a window in its most recent size and position. The 
active window remains active.
SW_SHOWNORMAL	Activates and displays a window. If the window is minimized or 
maximized, Windows restores it to its original size and position. An 
application should specify this flag when displaying the window for the first 
time.


If lpFile specifies a document file, nShowCmd should be zero.



Return Values

If the function succeeds, the return value is the instance handle of the 
application that was run, or the handle of a dynamic data exchange (DDE) 
server application.
If the function fails, the return value is an error value that is less than or 
equal to 32. The following table lists these error values:

Value	Meaning
0	The operating system is out of memory or resources.
ERROR_FILE_NOT_FOUND	The specified file was not found.
ERROR_PATH_NOT_FOUND	The specified path was not found.
ERROR_BAD_FORMAT	The .EXE file is invalid (non-Win32 .EXE or error in .EXE image).
SE_ERR_ACCESSDENIED	The operating system denied access to the specified file.
SE_ERR_ASSOCINCOMPLETE	The filename association is incomplete or invalid.
SE_ERR_DDEBUSY	The DDE transaction could not be completed because other DDE 
transactions were being processed.
SE_ERR_DDEFAIL	The DDE transaction failed.
SE_ERR_DDETIMEOUT	The DDE transaction could not be completed because the 
request timed out.
SE_ERR_DLLNOTFOUND	The specified dynamic-link library was not found.
SE_ERR_FNF	The specified file was not found.
SE_ERR_NOASSOC	There is no application associated with the given filename 
extension.
SE_ERR_OOM	There was not enough memory to complete the operation.
SE_ERR_PNF	The specified path was not found.
SE_ERR_SHARE	A sharing violation occurred.


Remarks

The file specified by the lpFile parameter can be a document file or an 
executable file. If the file is a document file, the ShellExecute function 
opens or prints it, depending on the value of the lpOperation parameter. If 
the file is an executable file, the ShellExecute function opens it, even if 
lpOperation specifies printing.
You can use ShellExecute to open or explore a shell folder. To open a folder, 
use either of the following calls:

ShellExecute(handle, NULL, path_to_folder, NULL, NULL, SW_SHOWNORMAL);

or


ShellExecute(handle, "open", path_to_folder, NULL, NULL, SW_SHOWNORMAL);


To explore a folder, use the following call:

ShellExecute(handle, "explore", path_to_folder, NULL, NULL, SW_SHOWNORMAL);


If lpOperation is NULL, the function opens the file specified by lpFile. If 
lpOperation is "open" or "explore", the function will force an open window or 
explorer.
