how to store an empty image in imageview?

 

[James Chamblin]

Do you mean create an image instead of loading one in from a file? You can initialize a bitmap with InitializeMutable and attach it to the imageview.

Sub Globals
   'These global variables will be redeclared each time the activity is created.
   'These variables can only be accessed from this module.
   Dim imvMyImageView As ImageView
   Dim bmpMyBitmap As Bitmap

End Sub

Sub Activity_Create(FirstTime As Boolean)
   'Do not forget to load the layout file created with the visual designer. For example:
   'Activity.LoadLayout("Layout1")
   imvMyImageView.Initialize("IV") 'initialize the imageview
   bmpMyBitmap.InitializeMutable(128,128) 'initialize the bitmap with size of 128 x 128
   imvMyImageView.Bitmap = bmpMyBitmap 'attach the bitmap to the imageview
   Activity.AddView(imvMyImageView,0,0,128,128) 'attach the imageview to the activity

End Sub

[Erel]

What do you mean with an empty image?

 

[gjoisa]

In my database table i am having image column. if the user selects the image then that image will be stored in that column. my question is how store the image if the user has not selected it..

 

[Erel]

You can store Null instead of the image.
