When a check box is displayed on a form, there is no property you can set
to have the check box show a check mark that is larger or a dfferent shape
than the small default check mark. Some users might prefer a larger or
different style of check mark. This can be achieved by setting the check
box Style Property to Graphical. This allows the Picture Property to be set
to a bitmap that appears as a check mark. Then you can change the setting
of the Picture Property to the bitmap when the check box is checked and set
it to no bitmap when it is not checked.
Step-by-Step Example to Create a Bitmap with a Check Mark in It
- In Windows 95:
Open Paint under Accessories. From the Image menu, choose Attributes.
Set the Units to Inches, and change the Height and Width to 0.15. Click
the "A" tool on the left side of Paint, and click the canvas. This will
allow the Text Toolbar to be chosen under the View menu. Select the
Wingdings font with size 12 or 14 (depending on the size check mark
needed), and choose Bold. After closing the Text toolbar, make sure
NumLock is on for the numeric key pad. Click the "A" tool again and
place the pointer (shaped as a cross-hair) on the upper-left corner of
the Paint canvas and lasso the whole area by holding down the mouse
button and dragging the mouse to the lower-right corner of the canvas.
This will be a very small area to work with.
Hold down the ALT key, and press the numbers 0252 on the numeric key
pad. When you release the ALT key, there will be a check mark on the
canvas. Choose New from the File menu, and start over if the check mark
is not centered properly on the canvas. After creating an acceptable
check mark, choose Save from the File menu, and save the bitmap with the
In Windows 3.x:
Open Paintbrush in the Accessories group. From the Options menu, choose
Image Attributes. Set the Units to Inches and change the Height and
Width to 0.15. From the Text menu, choose Font. Select the Wingdings
font with size 12 or 14 (depending on the size check mark needed), and
choose Bold. After closing the Font box, make sure NumLock is on for the
numeric key pad. Click the "abc" tool on the toolbar on the left side of
the canvas and place the pointer on the canvas by clicking the left
side. Make sure the pointer is on the left side of the canvas. Hold down
the ALT key, and press the numbers 0252 on the numeric key pad. When you
release the ALT key, there will be a check mark on the canvas. Choose
New from the File menu, and start over if the check mark is not centered
properly on the canvas. After creating an acceptable check mark, choose
Save from the File menu, and save the bitmap with the name chekmark.bmp.
- In Visual FoxPro, create a form, and place a check box on it. Change the
Style Property for the check box to Graphical. Select the Chekmark.bmp
file for the Picture Property, and delete the Check 1 Caption property.
The check box can be resized to a square if that's what you want.
- In the Click event for the check box, place this code:
IF THIS.VALUE = 1
THIS.PICTURE = "\(path)\chekmark.bmp"
THIS.PICTURE = ""
- Select a label from the Form toolbar and place it beside the check box.
Change its caption to MyCheckBox.
- In the Init event of the form, place the following code to give the
check box a checked value of 1:
THISFORM.CHECK1.VALUE = 1
- Run the form, and click the check box. Because it has a check mark in it
when the form starts, clicking it the first time should blank out the
If the check mark does not appear and disappear when clicked, it is
possible that the path to the bitmap is wrong. No error message should
appear when the Click event code executes if the bitmap doesn't exist where
its path is given or if its name is misspelled.
