|- style="background-color:#CCFFFF;"
|634A802
| [[Constant class/Change to Control method|Change to Control]]
|Changes the constant to a control and returns a reference to the control. LabVIEW automatically closes the reference to the constant.
|
|- style="background-color:#CCFFFF;"
|634A803
| [[Constant class/Change to Indicator method|Change to Indicator]]
|Changes the constant to an indicator and returns a reference to the indicator. LabVIEW automatically closes the reference to the constant.
|
|- style="background-color:#CCFFFF;"
|634A807
| [[Constant class/Change to Shared Variable Node method|Change to Shared Variable Node]]
|Changes the constant to a Shared Variable node and returns a reference to the Shared Variable node. If you do not specify a shared variable to bind to the node, LabVIEW creates a new shared variable. LabVIEW automatically closes the reference to the constant.
|
|- style="background-color:#CCFFFF;"
|634A804
| [[Constant class/Copy Data method|Copy Data]]
|Copies the data associated with the constant and saves it to the clipboard.
|
|- style="background-color:#CCFFFF;"
|634A800
| [[Constant class/Discon Typedef method|Discon Typedef]]
|Disconnects the constant from the type definition and returns TRUE. If the constant is not connected to a type definition, LabVIEW returns FALSE.
|
|- style="background-color:#CCFFFF;"
|634A806
| [[Constant class/Paste Data method|Paste Data]]
|Places the data from the clipboard into the constant.
|
|- style="background-color:#CCFFFF;"
|634A801
| [[Constant class/Update Typedef method|Update Typedef]]
|Updates the constant from the type definition and returns TRUE. If the constant is not connected to a type definition, LabVIEW returns FALSE.

In most cases, LabVIEW correctly preserves the default values of each instance when updating from the type definition. However, if LabVIEW is unable to map the previous default values to the updated controls or constants when updating instances, LabVIEW may lose or incorrectly preserve the default values of instances LabVIEW updates programmatically. Avoid updating type definition instances programmatically if the instances have custom default values and you plan to make extensive changes to the type definition.
