Windows offers a means of requesting a UWP package name via:

So im doing someting like this:

Code:
local proc = executeCodeLocalEx('OpenProcess', 0x1000, 0, 18320)
local _need=createMemoryStream()
_need.writeDword(0)
local _drivername=createMemoryStream()
_drivername.size=255*10
print(executeCodeLocalEx('GetPackageFamilyName', proc, _need.Memory, _drivername.Memory))
print(readStringLocal(_drivername.Memory,255*10))


But im gettin error 122 ERROR_INSUFFICIENT_BUFFER.

Could someone point me to what i'm doing wrong? Please.

try _need.writeDword(255)

also, you can use getOpenedProcessHandle() to get the handle to the currently opened process

Nope, setting it to true makes it empty string in return. In documentation of GetPackageFamilyName its PWSTR


My bad, u wrote third argument. All good. Thanks a lot, it works! Smile
