SalLoadApp to open non exe files

The SalLoadApp does not work for opening other EXE applications. I need to
pen a pdf, jpg, etc
how can I do this.

I tried:

Call SalLoadApp('CMD', '/c ' || "D:\\TEMP\\TEST.TXT"")

IT works but leave the cmd window open.

Thanks again

Try something like this instead:

Call ShellExecuteA( hWndNULL, 'OPEN', "D:\\TEMP\\TEST.TXT", '', '',
SW_SHOW )

Thanks for your response, I guess ShellExecuteA is an API function from the
clusterd CDK that I was avoiding to use.

I'll give it a try if I can import only ShellExecuteA.

"an API function from the clusterd CDK" - not true. It's a Windows API
function. Here's a sample from Thomas Wiedmann.

The function is a WIN32 API function found in shell32.dll (part of Windows).
You can 'import' only that function like this:

Code: Select all

External Functions
    Library name: shell32.dll
        Function: ShellExecuteA
            Export Ordinal: 0
            Returns:
                Number: DWORD
            Parameters
                Window Handle: HWND
                String: LPSTR
                String: LPSTR
                String: LPSTR
                String: LPSTR
                Number: INT
Description:
The ShellExecute function opens or prints a specified file. The file can be
an executable file or a document file. See ShellExecuteEx also.

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.

To do it without the SDK you can use

Call SalLoadApp('explorer.exe', 'D:\\TEMP\\TEST.TXT')
