How to get the file name of an image

    in an app I use an image control. I set the correspondending image during design time. Everything works fine.
    Now I want to know the file name during run time. How can I get this - like imgControl.Image.FileName ?

    With imgControl.Name I get the name of the control itself - but not the related filename.

    Please :sign0085:

    That is not possible.
    You can set the Image property from your code and store the file name in a variable:
    imageFile = "image.jpg"
    Image1.Image = imageFile

    Hello Erel,

    thank you for your very quick reply.
    I feared that this will not be possible.:(
    So I have to find an other workaround.

    I don't understand your problem....images added at designtime are KOWN files...Why not just add a variable to hold the image filename?

    If you can explain a bit more of why you need to "retrieve" the filename of a designtime set image controll filename....then maybe we can find a workaround..

    Hi there, new to forum.
    I wrote this very simple code which demonstrates how to get in real-time the filenames of specific file type group (such as documents or images) directly from a specific folder which contains mixed files.

    You may find it useful ;)

    PS: If it is off-topic please move to correct sub-forum. Thanx in advance

    thx for your help.

    The idea is to select (click) one of serveral images. That triggers an event which creates another control (i.e. AddImageButton). There is no problem to assign the Sender.Image to the ImageButton.Image.
    Please see the attached file to understand what I try to explain.
    Now I want to save the screen in an ini-file when the app will be closed.
    I thought it should be possible to get the properties of the different controls with GetControls("Form1"). Such like name, top, left, ...
    And the file name of the involved image.

    I know it is possible to keep a list collecting all this properties when triggering an event. But in my opinion it should be usefull and more efficient to prevent all this effort. Think about reindex when we delete one of these controls - or only change the position!

    Maybe there is a more uncomplicated solution.

    Technically it is not possible to get the image filename from an Image control. An Image control is not associated with a file at all, it contains a Bitmap object that contains the image that the Image control displays.

    The Bitmap object does not necessarily contain an image sourced from a file. It can be a new Bitmap from ImageLib, ImageLibEx or GDI+Desktop that has been created and drawn entirely by the application.

    I am afraid there is no alternative to tracking the filenames yourself.

    I found this thread and today I have the same Problem.
    I want to implement a Skin functionality to my Software.
    So the only way to realise this is during runtime.

    In my Project I've got many imagebuttons but only 20 different Pictures.
    Is there a way to get a logfile from the compilation where I'll find something like this

    form1.imagebutton1.Image = image1.png
    form40.imagebutton203.Image= image2.png


    So I can prepare a list for replace the Images.

    Are you by any chance asking about Android s/w? This the Windows Mobile forum (See header: Home Forums > Other Products > Basic4ppc (Windows Mobile) > Questions (Windows Mobile) ) so not the best place for answers...

    My Project is based on Windows mobile not android and I want to implement such a feature.
    So I think the only way is to parse *.bas files and generate such a list by my own

    After that I can provide this list with my application and replace all the pictures step by step.

    Have a look at this

    You need an arraylist alFiles and a table tblFiles.

    Sub Button1_Click
    ' add the main project file
    ' start scanning
        FileSearch (alFiles, AppPath, "*.bas")
    If tblFiles.ColCount<=0 Then
    End If
    For i=0 To alFiles.Count-1
    ' grab alle ImageButtons und füge diese der Tabelle hinzu
            FileOpen(c1, myFileName, cRead, , cASCII)
    ' erste Zeile
            r = FileRead (c1)
    Do Until r = EOF OR cancel=True
    ' Check the line
            If r="@EndOfDesignText@" Then
    ' Found end of Designer
    ' check for ImageButton
                myfound=StrIndexOf(r, searchfor,0)
    ' yes found
                If myfound>-1 Then
    ' split it
                    mySplit()=StrSplit(r, ",")
    ' grab name und image
                    ' main project file?
                    If  SubString(FileName(myFileName),StrLength(FileName(myFileName))-4,4)=".sbp" Then
    ' just a bas file
    End If
    ' add to table
    End If
    End If
            r = FileRead (c1)
    ' finally save it, provide this list with your application
        ' you can use it as a reference table
    End Sub
