Registry Mnemonics

From CometWiki

Using the Windows Registry in your IB Programs

Introduction:

The Registry Mnemonics allow you to create and manage Windows registry settings for your IB application. Entries may be made under either HKEY_CURRENT_USER\Software or HKEY_LOCAL_MACHINE\Software.

Syntax:

Print (RegCreateKey = Type$, BaseKey$, SubKey$) Creates a new registry entry.

Print (RegDeleteKey = Type$, BaseKey$, SubKey$) Deletes a registry entry and all of its name/value pairs.

Print (RegSetValue = Type$, BaseKey$, Name$, Value$, Type) Assigns the specified Name/Value pair of a given type.

Print (RegGetValue = Type$, BaseKey$, Name$) Returns the the Type and Value of the specified Name/Value pair.

Print (RegDeleteValue = Type$, BaseKey$, Name$) Deletes the specified Name/Value pair.

Discussion:

For all functions: Type$ = "USER" or "SYSTEM" where "USER" translates as HKCU\Software; "SYSTEM" translates as HKLM\Software BaseKey$ = an EXISTING registry key which may contain "\" for subkeys, For example: "Signature Systems\DocMgr"

Example:

Length 254 & Local RegKey$

SET STARTUPBASEKEY$ = "MyCompanyName\MyAppName\Settings"

SET REPORTSDIR$ = "RptDir"

print (RegCreateKey="USER","","MyCompanyName",0)

input Result$

print (RegCreateKey="USER","MyCompanyName","MyAppName",0)

input Result$

print (RegCreateKey="USER","MyCompanyName\MyAppName","Settings",0)

input Result$

print (RegCreateKey="USER",STARTUPBASEKEY$,UserName$,0)

input Result$

if strip(Result$) ne "+OK" UseReg = false

RegKey$ = STARTUPBASEKEY$ + "\" + User$

print (RegSetValue = "USER", RegKey$, REPORTSDIR$,RptDir$,1)

input Result$

RegKey$ = STARTUPBASEKEY$ + "\" + UserName$

print (RegGetValue = "USER", RegKey$, REPORTSDIR$)

input Result$

if sub(Result$,1,6) = "+OK 1:"
