GtpuSaveFileDialog1.Filter

oscar_f

Hello,
I'm trying to use the GTPUFileDialog but  when I set up the Filter , I got An  exception
"badly format"
In addition the  default extention seems  not  to  work,
For  example  if  i imput the "myfilename"  I'm expectign that the  fileName  has to be :
"myfilename.myext"
 
Here the code for  set up the GTPUFileDialog:
 
GtpuSaveFileDialog1.OverwritePrompt = True
GtpuSaveFileDialog1.InitialDirectory = "C:"
GtpuSaveFileDialog1.FileName = "MyModel.xml"
GtpuSaveFileDialog1.DefaultExt = ".myext"
'GtpuSaveFileDialog1.Filter = "xml"
GtpuSaveFileDialog1.AddExtension = True
