VB.NET Toolbar

Posted on 2004-08-22
Last Modified: 2008-03-06
Hi everyone.
I've upgraded a vb6 application to vb.NET
The quality of the images on the older toolbar & older imageList are great but if I create a new imageList and a New toolBar, the quality of the images on the new controls are lower !?
You can see the difference at:
I've loaded the same bitmaps...with the highest possible color depth (32dpi)

Also, do you know if I can put a control (like a progressBar or listBox) on a toolBar?
Feel free to comment.

I forgot the second part

you can add any control to tool bar by setting the Parent Property to the toolbar or add the control to Controls collection of toolbar as following:

        ProgressBar1.Parent = ToolBar1
        ComboBox1.Top = 0
        ProgressBar1.Top = 0

About the code above, do you know the difference between ToolBar1.Controls.Add(ProgressBar1)
and ProgressBar1.Parent = ToolBar1       ?

About the quality problem:
I made a new sample for myself and before adding images to the imageList, I set the colorDepth, Now it has its correct quality, but it causes another problem:
As far as I know, the Transparent color of the default Microsoft bitmaps (images of printer, cut, copty...) is Silver.
Now it does not work.
[keep in mind that imageList has a property TransparentColor and also the toolbar has that property in imageList property]
When I fix the Transparent color, the quality of the image noticably decreases!!!?

Please try to set the tranparent property of the imageList to silver before loading the images, otherwise it is not going to work at all. Maybe I'm wrong about the color "Silver" but it works in vb6 as Silver!

I figured that the problem was only with 3 images, so I edited the bitmaps...and now it looks much better.(The quality problem is solved)
I suggest anyone who may face this problem to edit the bitmaps or icons(if it does not look right) and choose Silver TransparentColor (for the Microsoft images) + ColorDepth before loading the images.

Hello kouroshparsa

it's will add the control into the Toolbar controls collection and will change the Parent to ToolBar

will change the parent of ProgressBar to ToolBar, and ProgressBar will added to collection controls too

I gave you the two, for doing the same thing, but I prefer to use ToolBar1.Controls.Add because it's more clear

>>Please try to set the tranparent property of the imageList to silver
you can use any color not onll silver, I have Icons with background Magenta, so I just choose the transparent color for the ImageList

Thanks for commenting on "the difference between add & parent".
I sure knew that I can choose any transparent color...I was talking about the common bitmaps of Microsoft with Silver transparent color at "\common\graphics\bitmaps"...What surprised me was that the same bitmap in vb6 looks different on vb.NET.
Well, as I said I fixed the problem by editing it.
