Re: CNG (Cryptography API: Next Generation)

Since the library uses advapi32.dll to generate hashes, I am worried that maybe different Windows systems will have different versions of advapi32.dll in their System32 folder, which might use slightly different implementation, causing a different hash to be generated, which would break my entire ap...

Re: DllCall return type Topic is solved

I think I understand what you're saying, insofar as the underlying binary data being the same for practical purposes, regardless of signness. But I was concerned that perhaps when ahk's source code for DllCall interacts with WinAPI, that ahk might be telling WinAPI "please return me a value of type ...

Re: DllCall return type Topic is solved

(prefix u or not doesn't matter). Are you sure because Prepend the letter U to any of the integer types above to interpret it as an unsigned integer. Strictly speaking, this is necessary only for return values and asterisk variables because it does not matter whether an argument passed by value is ...

DllCall return type Topic is solved

DllCall("LoadLibrary", "Str", "Psapi.dll") Why does the above work, given the LoadLibrary function returns a HMODULE, and we haven't specified a return type, as per: ReturnType: If the function returns a 32-bit signed integer (Int), BOOL, or nothing at all, ReturnType may be omitted. Otherwise, spe...

Does ahk automatically load ntdll.dll? Topic is solved

DllFile may be omitted when calling a function that resides in User32.dll, Kernel32.dll, ComCtl32.dll, or Gdi32.dll. For example, "User32\IsWindowVisible" produces the same result as "IsWindowVisible". However it seems I can call functions inside ntdll.dll, without having to specify ntdll.dll, whic...

Re: XGraph v1.1.1.0 : Real time data plotting.

I notice XGraph uses DllCall("RtlMoveMemory") According to WinAPI here , it resides in ntdll.dll, which is not part of ahk's automatically loaded .dlls (User32.dll, Kernel32.dll, ComCtl32.dll, and Gdi32.dll). According to ahk doc, the only time we can omit DllFile name, is if the function is inside ...

Re: FileSelectFile sometimes ignores my Rootdir (ahk2exe or 32/64bit issue?) Topic is solved

Re: FileSelectFile sometimes ignores my Rootdir (ahk2exe or 32/64bit issue?) Topic is solved

Just adding "\" sometimes works, sometimes fails. I finally got to the bottom of this. So the first time an application opens a FileSelectFile, Windows saves the starting directory parameter to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\FirstFolder Then, if your a...

the takeaway is timers are interruptible, loops arent Loops can be interrupted as long as they're not Critical, or at a higher Priority than the thread trying to interrupt it, or inside the script's exit routine.

Thanks.

I guess it must be something about my system configuration causing it. I will try a fresh install of Windows.

This may work for some but not all of the child processes. Use something like Process Explorer to confirm (View -> Select Columns -> Process Performance -> Base Priority. 8=Normal, 13=High). #Persistent Run "c:\Program Files (x86)\Firefox Quantum\firefox.exe" --profile "c:\Users\username\AppData\Roa...

With some experiments and in hindsight, I just need the trailing "\". (You don't need GetReliablePath, pneumatic.)

Re: UTF-8 ini files

Thanks.

To be safe I changed all my ini files to UTF-16, aka "USC2-LE-BOM", by using the parameter UTF-16 with FileAppend.

In future I think I'll just avoid using iniread/write and do it manually.

Re: UTF-8 ini files

I guess UTF-8 is using 1 byte per character which makes it compatible with ANSI which Get/WritePrivateProfileString are interpreting the file as.

But I still don't understand how it knows how many bytes per char are being used by UTF-8 as it could be up to 3.
