Example of .INI file
[WD examples]
Name1 = WDInstall
Name2 = WDBench
[Description of WDInstall]

LST = 43
Page = 12
// Default choice read in the .INI
nProduct is int = Val(INIRead("USER", ...
"LastProd", "", fExeDir() + "\Port.INI"))
IF nProduct > 0 THEN ListSelectPlus(LIST_Product, nProduct)
Syntax

    • the string corresponding to the keyword is empty,
    • the keyword is not found,
    • the file is not found.
  • Empty string (if <Not found> is not specified or if it is equal to an empty string) in the following cases:
    • the string corresponding to the keyword is empty,
    • the keyword is not found,
    • the file is not found.
<Section>: Character string

Remarks

Reading the persistent values

To read the persistent values in a INI file (saved with SaveParameter), use LoadParameter.

Miscellaneous

  • To read in the registry, use the functions specific to the registry: RegistryQueryValue, ...
  • INI files are limited to 64 KB.
  • TSE: Bu default, INIRead uses the Windows directory.
    Caution: Until version 21, INIRead used the user's Windows directory by default.
    Reminder: In TSE mode, the access to a '.INI' file with a relative name is not recommended. We advise you to use one of the following solutions:
Business / UI classification: Business Logic
Component: wd290std.dll
Minimum version required
  • Version 9
