Stored procedures
Writes a specific value into an INI file (or into a file structured like an .INI file). You can:
  • write the value of a keyword found in a specific section,
  • create or delete a keyword,
  • create or delete a section.
Example
// Store the selected product in the .INI
INIWrite("USER", "LastProd", ...
NumToString(ListSelect(LIST_Product)), ...
fCurrentDir() + "\Port.INI")
Reports and Queries
Example of .INI file:
[WD examples]
Name1 = WDInstall
Name2 = WDBench
[Description of WDInstall]
Caption = Use the control panel of Windows
LST = 43
Page = 12
// Write into the [WD examples] section
INIWrite("WD examples", "Name3", "WDExample", "C:\Temp\ExamplesLST.INI")
Syntax
<Result> = INIWrite(<Section> [, <Keyword> [, <Value> [, <File>]]])
<Result>: Boolean
  • True if the operation was performed,
  • False otherwise.
<Section>: Character string
Name of section where the write operation will be performed. The section is automatically created if it does not exist.
Remark: This name cannot contain the "-" character.
<Keyword>: Optional character string
Name of keyword containing the information to write. This keyword s automatically created if it does not exist.
The section will be deleted if this parameter is an empty string ("") or if it corresponds to NULL.
<Value>: Optional character string
Text to write for the keyword and the specified section. The keyword will be deleted if this parameter is an empty string ("") or if ti corresponds to NULL.
Remark: This name cannot contain the TAB character.
<File>: Optional character string
Full name of file to complete (with its extension).
  • The WIN.INI file will be used if this parameter is not specified.
  • If only the path is not specified, the file will be sought in the Windows directory.
  • The directory will not be created if it does not exist.
  • The file will be created if it does not exist in the specified directory.
Remarks

Writing into a INI file in Unicode mode

Your application operates in Unicode mode ("Use UNICODE strings at runtime" checked in the "Unicode" tab of configuration description).
In this case, to write into an INI file, this INI file must be in Unicode format, which means that it must have a Unicode BOM header.
Example:
fCreate(gsINIFile, foUnicode) // creates gsINIFile with BOM UNICODE
INIWrite("French", "Country", "French",gsINIFile)
INIWrite("中国","国家", "中国", gsINIFile)

Miscellaneous

  • We do not advise you to write into the WIN.INI file.
  • To write into the registry, use the functions specific to the registry: RegistrySetValue, etc.
  • The INI files are limited to 64 KB (in Windows 98).
Reports and Queries

Windows Vista (and later)

The programming standards of Windows do not advise you to write:
  • into the WIN.INI file
  • into the system directories (Windows directory, "Program Files" directory, ...).
In Windows Vista (and later) with the UAC mechanism enabled, the administrator privileges are required to perform these operations. If the application does not have the required administrator privileges, the UAC mechanism will redirect the files (called virtualization) to a directory specific to the user who is using the application (C:\Users\<LOGIN>AppData\Local\VirtualStore\Windows\). The files can be read again by INIRead used in the same application. This virtualization mechanism of files is proposed by Windows Vista (and later) for compatibility and it is not available in 64 bits.
Caution: If the INI file is automatically virtualized by Windows Vista (and later), the INI file cannot be shared between several applications (especially if these applications use different privileges).
Programming tip: To create a INI file without having the administrator privileges:
  • do not use the WIN.INI file (the <File> parameter must be specified),
  • avoid writing to the Windows directory or to the "Program Files" directory,
  • use the system directory of the application (returned by SysDir with the srAppDataCommun constant, for example).
Component: wd290std.dll
