Substitutes a report block for another block while the report is printed.
After executing the function iSubstBlock, when the initial block is to be printed, the following events will be executed:
  • "Before printing" event of the substitution block.
  • print the substitution block.
  • event "After printing" the substitution block.

Example
// Substitution of page header
iSubstBlock(PageHeader, Iteration1)
// End of substitution of page header
iSubstBlock(PageHeader, "")
Syntax
iSubstBlock(<Block to be substituted> , <New block>)
<Block to be substituted>: Character string with or without quotes
Logical name of the block to replace. This name was defined in the report editor, in the block description ("General" tab, "Name" control).
<New block>: Character string with or without quotes
Logical name of the block used for the substitution. This name was defined in the report editor, in the block description.
If this parameter corresponds to an empty string (""), the current substitution for the block <Block to be substituted> is cancelled.
If this parameter is equal to <Block to be substituted>, the current substitution is cancelled.
Remarks

Substituting the first block of the page header

To substitute the first block at the top of the page, the function iSubstBlock must be used in an initialization event of the report (for example, in one of the events of the document start block or in the "Opening" event of the report). These events will be executed before this block is printed.

Substituting the Page Footer block

To avoid display problems, the Page Footer block and its substitution block must have the same height.

Various

  • You will get the same result by performing the following operations:
    1. Make the block invisible (..Visible).
    2. Use iPrintBlock.
  • To substitute a Page Footer block, we recommend that you use blocks with the same height.
  • Versions 19 and later
    In most cases, we recommend that you use planes in the report as they are easier to use and to implement (rather than block substitution). See The planes for more details.

[ + ] This example presents a solution for duplex printout that can be disabled, which means that the reverse sides may not be printed.
In this example, the general sales conditions will be inserted into a report by using the principle of block substitution.
These general conditions are inserted between each page.
The example allows you to print:
- in duplex mode if the printer supports it,
- on the front side of pre-printed sheets for which the general sales conditions are printed on the back side.
