PRB: LoadPicture Displays 16 x 16 Icons as 32 x 32

• Microsoft Visual Basic Learning, Professional, and Enterprise Editions for Windows, versions 4.0, 5.0

SYMPTOMS

When using the LoadPicture Function to display a 16 x 16 icon in an Image control, or any other control that uses the LoadPicture function to store images into the Picture object, the icon will display at 32 x 32.

RESOLUTION

To work around this problem, use one of the following methods.

• Use a 16 x 16 bitmap instead of an icon.

  -or-

• Use an Image Control and set the Height and Width to be the same as the icons. For example:

        Image1.Picture = LoadPicture(<path to your icon>)
        Image1.Stretch = True 'Needed so the image does not get clipped
        'The next two lines assume that the form's ScaleMode is Twips
        'It changes the Image control to be 16 x 16 Pixels
        Image1.Width = (Screen.TwipsPerPixelX * 16)
        Image1.Height = (Screen.TwipsPerPixelY * 16)
  

STATUS

This behavior is by design.

MORE INFORMATION

LoadPicture always loads a 32 x 32 icon. If the icon file being loaded contains a single 16 x 16 image, LoadPicture stretches it to 32 x 32 before storing it in the Picture object of a control.

Steps to Reproduce Behavior

The steps below illustrate an example that displays a 16 x 16 icon in an Image control.

NOTE: You can use IMAGEDIT.EXE that ships on the Visual Basic 5.0 CD-ROM to create icons. This tool is located in the Tools\Imagedit directory on the Visual Basic 5.0 CD-ROM.

1. Create a new project. Form1 is created by default.

2. Place an Image control on Form1.

3. Add the following code to Form1:

         Private Sub Form_Load()
             Image1.Picture = LoadPicture(<Path to your 16 x 16 icon>)
         End Sub
   
   

4. Run the form by choosing Start from the Run menu. Note that the icon is displayed as a 32 x 32 icon.
