Is there any open file GUI

[jincheker]

Can I build a GUI in vizard, like below, that allow user to open and choose some files and import them into vizard?

[jincheker]

I mean build a button, and when click the button, it can call an open file GUI in which people can browse and choose files to be open?

There's an example over in the Vizard 2.5 forum. Here's a link to it:http://forum.worldviz.com/showthread...light=win32gui

I've tried it under Vizard 3 and it works, no problem.

Sorry for bumping this thread but when I attempt to use the code in this example I get this error:

Traceback (most recent call last):
** Load Time: 0.01 seconds
  File "<string>", line 11, in ?
  File "Vizard2.py", line 3, in ?
    inFileDlg = win32ui.CreateFileDialog(1, '', 'foo.txt')
TypeError: None is not a valid string in this context

I have used the exact code in the given example but still no joy

I really need to be able to navigate to and open various files and this seemed the ideal way to do it except I can't get it to work!! I'd be really grateful for any ideas regarding this,

Cheers

Ok, I'm getting somewhere here I think. Here's what I am using now:

def ChooseFile():
	"""You can find documentation for CreateFileDialog at the following site:
		http://aspn.activestate.com/ASPN/docs/ActivePython/2.5/pywin32/win32ui__CreateFileDialog_meth.html"""
	parent = win32ui.CreateWindowFromHandle(viz.window.getHandle())
	dlg = win32ui.CreateFileDialog(1,'','',0,'',parent)
	if dlg.DoModal() == win32con.IDOK:
		file = dlg.GetFileName()
		inFileName  = dlg.GetPathName()
		print file
		print inFileName

- Thanks farshi

However, what I would really like to do is open the selected file, so I tried adding:

		FILE = open(file, 'r')
		
		for line in FILE:
			print line

- but all I get is

ÐÏࡱ

So my question is - what am I doing wrong here, I just want a participant to be able to select a file which is then read in / parsed into useful chunks of data.

Also when exiting winviz after running this I get a - "winviz.exe has encountered a problem and needs to close. We are sorry for the inconvenience." from windoze

Hi nige777

This is what i use and it seems to work

	infile = open(file,"r")
	for line in infile.readlines(): 
		#do stuff
	infile.close()

Thanks

@TarkaDahl - thanks for the reply unfortunately it was my bad as I needed to be using the excellent 'xlrd' library to be able to work with Excel files
