windows network password

[Neil.Pate]

Hi there.

I need to read files off a networked machine (using LabVIEW), but trying to open the files fails until I have manually browsed to the networked PC and entered a valid username and password on the dialog that pops up. Is there any way to do this automatically via either some Win32 command or LabVIEW? Both machines are running Win2k, and I am using LabVIEW 7.0 Express

thanks
Neil

Windows API call: mpr.dll
WNetConnectionDialog: simple
WNetConnectionDialog1A: complicated structure parameter not easily done
in LabVIEW itself, so you would need to write a cover DLL.

More possible functions:

WNetAddConnection[2][3]A
WNetUseConnectionA

Rolf,

thanks for your reply. I think the WNetConnectionDialog API function is exactly what I need, but it needs a handle to the owner window as an input parameter, and I have no idea how to obtain this via labview (another Win32 function I suppose???)

Neil,

You can use GetActiveWindow (user23.dll, no inputs needed). You can also use
FindChild, but it's more difficult. I suppose the OpenG toolkit has
functions for this too.

Regards,

Wiebe.

Search on the Developer Exchange for windows API utility or go directly to

There are functions to retrieve the Windows handle of a window by name.
Bascially you query the Title of a VI through a VI property node and
pass that to the Get Window Handle.vi or similar function. The returned
int32 is the actual window handle.
