Do you mean a path within you're application or a variable path?

I think you cannot. When the picture is first put in the control via the picture property it pulls the binary data from the file and stores its own copy. Hence , the creation of frx's etc.There is then no maintained connection to the original file unless the information was stored somewhere at the time.

I don't know of one but you could try creating your own Activex control with the image conrol as a constituent and persisting the path in its own propbag.

You could use the Tag property to hold the path name.

Why not just store the path in a local or global variable?

Option Explicit

Private sPicPath As String

Private Sub Command1_Click()
    'Use the path somewhere else
    MsgBox sPicPath
End Sub

Private Sub Form_Load()
    'Load the picture at runtime
    sPicPath = "c:\test.bmp"
    Picture1.Picture = LoadPicture(sPicPath)
End Sub

I've looked through the API - there is NO API CALL FOR IT: If there is no API call for something, then it is impossible to do. (duuh!)


When an image is loaded, basically, that image is given a "process id" (it's a little different, but fundamentally the same) - this is just a number, that the control uses, and by extracting something from the number, it then gets the path of the image (or perhaps the image is loaded into memory already...), but anyway, there is probably a way of using about 1,000,000 API calls to do it, but the method below works fine:



Public Function LoadPictureB(Filename as string, ApplyTo as Picturebox) as long

on error goto ErrorHandler
ApplyTo.tag = Filename
ApplyTo.picture = loadpicture(Filename)

'Now, the function has succeded, return an all ok:
LoadPictureB = 0
Exit Function

ErrorHandler:
'Do whatever err loop u want here:
select case err.number
'...
case else
    msgbox "Error encountered while loading the image """ & Filename & """. Please check and retry",vbcritical,"Error Occurred"
end select
LoadPictureB = err.number
'You don't need the return, but it looks nicer, and u mite want to see if an error occurred...
End Function




'The above code should work fine - it's basically just a simpler way of the code above.
