Question

I’m trying to get the Windows temppath and write it to the registry, but all I get in the registry are squares ?

Code:

tmpFilePath db 256 dup(?)

Get temp path

main PROC
     invoke GetTempPath, 255,addr tmpFilePath`

Write to registry

WriteReg PROC 

    invoke RegCreateKeyExW,HKEY_CURRENT_USER,offset regkey,NULL,NULL,REG_OPTION_NON_VOLATILE,KEY_ALL_ACCESS,NULL,offset hIDKey,NULL

    .IF eax==ERROR_SUCCESS
        invoke lstrlenW,offset tmpFilePath
        add eax,eax
        add eax,2
        invoke RegSetValueExW,hIDKey,offset keyname,NULL,REG_SZ,offset buf,eax
        invoke RegCloseKey,hIDKey

You need to use GetTempPathW in order to get a file name that is compatible with RegCreateKeyExW.
