overwrite regkeys

[aemik]

hello,

i use "overwrite off" for my "file" commands.
can i also use it "writeregstr ..." ?
i dont want to overwrite regkeys. is it possible?

no, but you can try to read it first, and only write if it sets the error flag (or returns empty string)

[pospec]

Yes, that's right. The best way is write your own macro ;-)

[aemik]

I have a long list (50) of RegKeys like this:

WriteRegStr HKLM "Software\x\x" "abc" "def"
...
WriteRegStr HKLM "Software\x\x" "asd" "gfd"


I only want to write them if they not exist. Can you please give me the code for this problem??

Thnaks for your help

Yes, I can. Sorry for that Czech names

I can also provide script which converts .reg file into NSIS commands like ${registry::________} ... ... ... ...

[pospec]

The script was too big.

[aemik]

thank you for help.

How can i include this script and how can i use it for my registry keys?

[pospec]

Copy / paste?

Try something like ${ZapisReg} "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion" "ProductId" "this is really CRAP!" "REG_SZ"

[aemik]

where is registry.nsh?

Just use a macro:

code:
!macro _WriteReg Type Root Key Name Value

  Push $R0

  ClearErrors

  ReadReg${Type} $R0 `${Root}` `${Key}` `${Name}`

  Pop $R0

  IfErrors 0 +2

    WriteReg${Type} `${Root}` `${Key}` `${Name}` `${Value}`

!macroend



!define WriteRegDWORD `!insertmacro _WriteReg DWORD`

!define WriteRegBin `!insertmacro _WriteReg Bin`

!define WriteRegStr `!insertmacro _WriteReg Str`

${WriteRegDWORD} HKLM `Software\MyApp` `Blah1` 1
${WriteRegBin} HKLM `Software\MyApp` `Blah2` ABCD
${WriteRegStr} HKLM `Software\MyApp` `Blah3` Hello

Edit: shortened.

Nice. Why should I do it simply if I can do it intricately?
