In Visual FoxPro version 3.0x and version 5.0x, some of the bitmaps will turn black instead of dim when the button is disabled.


Use Microsoft Paint or any image utility to open up the bitmap file and re- save the file to monochrome type instead of color.

If you re-save the bitmap to a different file name, you need to re-load the Picture property with the newly saved bitmap in order for the newly saved bitmap to take in effect.

However, if you save the bitmap back to the same file name in Visual FoxPro version 5.0x, perform the following steps:

  1. Unload the bitmap from the Picture property of the object.
  2. In the Command window, issue the following command:

          CLEAR RESOURCE [bitmap filename include the full path]
          * For example,  CLEAR RESOURCE C:\VFP5.0\TEST.BMP
  3. Reload the bitmap to the Picture property of the object again.

In Visual FoxPro version 3.0x, one must re-start Visual FoxPro for the newly saved bitmap to take in effect in the object.


Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.


This problem does not happen in Windows 95. This problem is pertaining only to Windows NT 4.0.

Steps to Reproduce Behavior

  1. Create a form with two command buttons.
  2. Select the picture property of the first command button and use the Save.bmp file in the \Samples\Graphics\Bmps\Offctlbr\Small\Color folder. In Visual FoxPro 6.0, the files are located under \Microsoft Visual Studio\Common\Graphics\Bitmaps\OffCtlBr\Small\Color
  3. Put the following code in the Click event of the second button:

          Thisform.Command1.Enabled = !Thisform.Command1.Enabled
  4. Save and run the form.

NOTE: Click on the second command button to disable the first command button. The bitmap on the first command button turns black instead of dim.
