How to get tooltip to not draw black rectangle on setting it's size on popup?

[OverKillasdwqe]

all i want is a transparent (less opacity tool tip)

here is what I've so far

public partial class CustomToolTip : ToolTip    
{
    public CustomToolTip()
    {
        InitializeComponent();
        this.BackColor = Color.FromArgb(127, 0, 0, 0);
        this.OwnerDraw = true;
        this.Popup += new PopupEventHandler(this.OnPopup);
        this.Draw += new DrawToolTipEventHandler(this.OnDraw);
    }
 
    protected override CreateParams CreateParams
    {
        get
        {
            CreateParams CP = base.CreateParams;
            CP.ExStyle = CP.ExStyle | 0x20;
            return CP;
        }
    }
 
    private void OnPopup(object sender, PopupEventArgs e)
    {
        e.ToolTipSize = new Size(200, 100);
    }
 
    private void OnDraw(object sender, DrawToolTipEventArgs e)
    {
        e.Graphics.FillRectangle(new SolidBrush(this.BackColor), e.Bounds);
    }
}

but i end up having a black rectangle at setting the tooltip size which i can't get ride of



any idea how could i draw without setting size or even remove that black rectangle ?

^ that what i've posted on programming forums but as people here can relate to conquer then i should say im going after conquer's item tool tip kind thing (if that isn't obvious by now)

i also want to add that this is the reason for not doing it with this ways

1- as for transparent form : it lose focus of the previous form plus it's gay
2- custom controls : C# graphics is way way way too good for documentation and not strict at all, everything is pretty straight forward >.< IKR lmao, but seriously i reached a certain point where i don't have suitable parent to draw on a custom transparent control ( some controls redraw over it for certain reasons ) and no control support real transparency (only taking it's parent backcolor) but won't let me set createprams 0x20 flag

answer by Loathing, maybe you folks wanna have a look how it was done
Updated the solution with the final class (didn't want to release it but duh)

Change dwStyle in CreateWindowEx to WS_POPUP if you don't like the balloon..

I hope that helps, Good luck.

I think this might prove useful to you..

it's same or less what i do but mine is a bit more dynamic and a bit more complicated (not just shops, it's like full client manager)
i read all items, all icons, all shops, most of the ani and ini files
i then cast them to lists of objects and i write them to a binary file (to read them back with like 100 times faster than normal txt files)
also i read and convert images at run time, doesn't take any time or effort so i think it's best that way to fit my app

but with that being said, i love some techniques you used XD im stealing what i can :P :P

Sure help your self

That was a little test project that i put together to implement some type of a drag/drop functionality for the shop icons..

The idea was to be able to drag any item in the inventory/shop etc and drop it in the search box and it will display all sorts of information about the item without any effort.. yes that's how lazy i am =))
