Caption (Property)

In french: Libellé

In a database, ..Caption is used to:

Find out the caption associated with a file item.
Remark: The item was created in the data model editor or by programming.
Find out the caption associated with a data file.
Remark: The data file may have been created in the data model editor or by programming.
Find out and modify the connection caption. The connection can correspond to:
- a connection described in the data model editor,
- a connection described by HConnect, HDescribeConnection or HOpenConnection.
- a connection described by a Connection variable.

In a report, ..Caption is used to find out or modify the text:

of a Static control.
of a Link control.
Versions 17 and later
of a Chart control.
New in version 17
of a Chart control.
of a Chart control.

In a window or in a page, ..Caption is used to:

Find out and modify the caption of a control in a window or in a page.
Find out and modify the caption of a menu option.
Find out and modify the title of a window or page.

Reminder: The initial caption of a control, window, page or menu option is defined in the editor during the object description.

Example

// Find out the caption associated with the Customer.Title item
ResCaption = Customer.Title..Caption

// Modify the text in the "STC_IntroControl" Static control
STC_IntroControl..Caption = "Dear Sir" + Customer.Name
// Equivalent to: STC_IntroControl..Caption = "Dear Sir [%Customer.Name%]"

Syntax

Remarks

Content of Static control

To retrieve the value of a control or the value of an item in a Static control:

In the report editor: insert [%<Control name>%] or [%<Item name>%] directly into the caption of the control.
In programming: two syntaxes are available with ..Caption:
- use directly the [%<Control name>%] or [%<Item name>%] string in the string that corresponds to the caption. For example:
  
  STC_IntroControl..Caption = "Dear Sir [%Customer.Name%]"
- use the name of the control or the name of the item in the caption. For example:
  
  STC_IntroControl..Caption = "Dear Sir" + Customer.Name

Equivalence

..Caption is equivalent to ..Value.

To retrieve the text of a Static control, the following syntaxes are equivalent:

ResCaption = <Name of Static control>..Caption

ResCaption = <Name of Static control>..Value

ResCaption = <Name of Static control>

To modify the text displayed in a Static control, the following syntaxes are equivalent:

<Name of Static control>..Caption = <New text>

<Name of Static control>..Value = <New text>

<Name of Static control> = <New text>

Caption associated with an Image control

..Caption returns or replaces the current image by the image whose name is passed as parameter.

..Caption is equivalent to a direct assignment of the control with the name of the image (Control = Image_Name).

The Image control includes a caption: therefore, ..Caption is used to modify this caption. If the new caption does not correspond to a valid image, the caption of the Image control is modified.

Caption associated with a button

..Caption can have two actions:

replace the image of the button (the name passed as parameter corresponds to an image file),
return or replace the button caption (the text passed as parameter is not an image file name).

For example:

// Modify the image of a graphic button
BTN_Button1..Caption = "Help.BMP"

// Modify the caption of a text button
BTN_Button1..Caption = "New caption"

Remark: If the specified control contains the & character, the letter that follows the & character is considered as being the shortcut of the control.

Limits

In a report, ..Caption only applies to the "Static" controls and to the "Link" controls.
