View 1 RepliesIn a form I have an ImageList named MainLogoImageList containing a 100x100 pixel 32-bit colordepth image. That is my app logo.
I am too lazy to set up an icon editor and edit an icon of that logo, or convert the image to an .ICO file. (Ergh, well, I am not allowed to install custom utilities.)
To set my forms' icon, I use
Icon = IconFromImage(MainLogoImageList.Images(0))
in the OnLoad event handler to set the window icon.
In my about box, i have a PictureBox with no image. In its OnLoad event, I use
LogoPictureBox.Image = MyMainForm.MainLogoImageList.Images(0)
Icon = IconFromImage(MyMainForm.MainLogoImageList.Images(0))
to set the About box's icon and content.
So far, so good, the icon looks pretty good for a being created from a 100x100 pixel bitmap.
Is there an easy "no utility required" :-) way to get the icon that is returned my IconFromImage saved into an .ICO file so that it will keep the color depth when loaded as the app icon? I want to use exactly the icon that IconFromImage creates.
Saving it using
Dim S As New FileStream("MyAppIcon.ico", FileMode.Append, FileAccess.Write, FileShare.Write)
Icon.Save(S)
S.Close()
in the main form's OnLoad event handler and loading that .ICO file as the app icon in VS's project properties dialog yields and icon that is obviously converted to 16 colors, and looks awful.

How do you change the cursor image to an image from the project resources?
The methods I have found either don't work or only change the image within the form, and reverts back to default when the mouse leaves the window.
means the images that will display in the picturebox is based on the value shown on the textbox (ProjID)..
Please see code below..
