- Description
-
The RegRead command reads a value from the registry and stores it in the specified variable. The command returns True on successful execution, or False if an error occurs.
- Important
-
If the type of the registry that was read is REG_MULTI_SZ, only the value in the first line is stored in the variable.
If the registry value to be read contains 1,025 or more bytes, an error occurs and 0234 (More data is available.) is output. Do not attempt to read a registry value longer than 1,024 bytes.
- Example
Dim DBflag RegRead(HKEY_LOCAL_MACHINE _ ,"SOFTWARE\WOW6432Node\Hitachi\JP1/Script\Option" _ , DBflag, "Debug") If DBflag = 1 Then Exit End- JP1/Script version
