getOpenFileName for multiple files?

adnanmg — Thu, 04 Jun 2009 04:54:00 GMT

Hi,

in Max 2010, I am using the getOpenFileName command via a button in a rollout to select files. Is there any way to select multiple files? I want the user to be able to use the file open dialog to ctrl select multiple files in a dir and for the command to return an array of values.

This way the user can perform a task on multiple files at once instead of one at a time.

Any ideas using this or other commands? I don't want to use all the files in the dir so it is important that the user can select specific ones in the open file dialog.

Thanks!

Adnan

This should be possible via DotNet.

Although I did try adding the following to a rollout but didn't have much luck. Can anyone work out why this wouldn't work?

Rollout Test "" width:400 height:400
(
DotNetControl Test_FileBrower "System.Windows.Forms.FileDialog" pos: width:400 height:400
)

CreateDialog Test ""

Here is a function I wrote that works as a direct replacement for the built-in GetOpenFilename():


fn GetMultiOpenFilenames caption:"Open" filename:"" types:"All Files &#40;*.*&#41;|*.*" default:1 =
&#40;
 local dlg = DotNetObject "System.Windows.Forms.OpenFileDialog"
 dlg.multiSelect = true
 dlg.title = caption
 
 local p = getFilenamePath filename
 if doesFileExist p then
 dlg.initialDirectory = p
 
 -- MAXScript getOpenFilename uses trailing |;
 -- OpenFileDialog filter does not.
 if types == "|" then
 dlg.filter = &#40;substring types 1 &#40;types.count - 1&#41;&#41;
 else
 dlg.filter = types
 
 dlg.filterIndex = default
 
 local result = dlg.ShowDialog&#40;&#41;
 if &#40;result.Equals result.OK&#41; then
 dlg.filenames
 else
 undefined
&#41;

Sorry, this new forum software converted all the double-dashes and quotes inside the 'code' tags.

Here is a second attempt at posting my GetOpenFilename() replacement function, this time as an attachment.

Am I missing something, or can I neither delete nor edit replies in this new forum software?

Hm, attachments don't seem to work, either, at least not for .ms files. Trying with a zip.
