How Do I grey out box in Lab windows CVI 8.5

[niner710]

Hi,

I want to grey out and disable a textbox/checkbox when I run a specific test on Labwindows CVI 8.5. Is there a function to do this? Can anyone tell me how? Thanks.

SetCtrlAttribute(panel, control, ATTR_DIMMED, 1);  

Setting to 1= grayed out, 0=normal.

Good Luck
