    Hi Andrew....
    I finally solved my initial problems in working with FormExDesktop...And guess what!?!?!
    I found new problems.....:sign0060::sign0161:

    Here's a couple of screenshots...

    I was just trying to add an image button with a very simple bmp image.....Or a png with transparency, if possible...

    The imagebutton (CloseButton) was added to a native b4ppc form, and the form is being handled by a FormExDesktop object called FX...

    Code:
    Sub SetControls
       FX.New1(
    "MainForm")
       FX.DrawImage=AppPath & 
    "\BackGround.PNG"
       FX.BorderStyle=
    2
       FX.TransparencyKey=FX.BackColor
       CloseButton.BringToFront
       
       FX.Run 
    '-This MUST be the last statement on the sub
    End Sub
    I also tryied to create a Non-native form using new2 method, but the behaviour is the same...

    Thanks for the fast reply and I am glad to say I found a workaround the transparency issue...
    IF one uses as the imagebutton a png with a transparent background ( I achieved this with PaintShop pro BackGround eraser), then un-setting the transparency propertie has NO effect in the image transparent regions...Thus rendering the Button...tranparent...

    EDIT:
    NO it has NOT been solved, sorry for misleading you..
    My image button is just small enough to blend in to the background..
    Again, Thank You Andrew!!:sign0188:

    Thinking with my buttons, I started wondering if controlsExDesktop would have a compatible ImageButton....
    Unfortunatly NO...
    Perhaps a "small" update would provide a workaround?

    ImageButton is not a button or a Windows Forms control at all but is a custom control so would have to have the coding replicated in ControlEx...

    Look at this earlier thread for a couple of ideas. This was before the cs files for merging were available and so before I could look at the code and understand why an ImageButton didn't work on a FormEx.

    I've been playing around with a picturebox dll, and setting the props names as close as possible to the ones used in b4ppc...
    I'm having some trouble with ImageLayout as it expects an integer and I would like to pass a string equal to the one used in b4ppc image modes.
    I understand this is possible with the switch keyword but I cant get it to work...
    Anyway...
    After exposing all the methods and props needed, I will need to expose at least the 3 events supported by the b4ppc image button...
    So I guess about 60% of the FormExDestop compatible IMAGEBUTTON.DLL is done...
    (Yes, transparency has been acomplished)

    Code:
    switch (modestring.ToLower())
    {
      
    case "cstretchimage":
        Pbox.SizeMode = PictureBoxSizeMode.StretchImage;
        break;
      
    case "ccenterimage":
        Pbox.SizeMode = PictureBoxSizeMode.CenterImage;
        break;
      default:
        Pbox.SizeMode = PictureBoxSizeMode.Normal;
        break;
    }

    Thanks Andrew...
    I was not the exct codeI needed, not because of the controls name, but because, in order to achieve transparency, I'm setting the BackgroundImage instead of the Image..
    So I used the BackgroundImageLayout prop and it now works a treat...

    Now for the hardest part...the events...

    OK, So I now have a fully working ImageButton/PictureBox, with all the normal props, methods and events used in b4ppc...
    I will post it later on, If I can resolve one last thing....
    How do I achieve the image shifting that ocours when the control is clicked?
    Since I'm working with a Picturebox as a base for my ImageButton, this is not a control standart behaviour...
    But perhaps I can do this offset in the click event?
