Hey,

someone programming on windows and knows how to wrap the wchar arrays in nimrod strings?

system.newWideCString, all defined in lib/system/widestrs.nim which is included by system.

Hi,

K i could print something out, but it was really cryptic. I've ported the tlhelp32 and tried iterating over the processnames in the snapshot. If somone wants to try it: https://github.com/FroznPanda/pandanimwin Tried something like:

if Process32First(snapshot, pe.addr):

while Process32Next(snapshot, pe.addr):

var wstr: WideCString = newWideCString("", MAX_PATH)

for i in 0..MAX_PATH - 1:: wstr[i] = TUtf16Char(pe.szExeFileName[i])

echo(wstr)

if someone tried it and want to let me know it, im gladful.

I haven't tried it yet, but the problem might as well be the echo that prints to the console which doesn't use Unicode but some other archaic character set. You can redirect the output with >filehere.txt and then look at filehere.txt with a reasonable to see if it contains valid Unicode.

Hello,

i think Araq is right about the character set of the console. newWideCString() works for me with DirectWrite, which uses Unicode (WCHAR array)

With best regards, enurlyx

Hi,

experimented the last day again with it printed the string out to a file. The output was a string of asian letters. Tried it in C. It's working(who would have thought). Then I printed out the values from the WCHAR array in nim. For some reason the array is getting filled with wrong values. That's what i found out so far, will look into it again.

It works for me when I declare it as szExeFileName*: array[MAX_PATH, char] and then do this:


proc main =
  var pe: PROCESSENTRY32
  pe.dwSize = sizeof(PROCESSENTRY32).DWORD
  let snapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0)
  if Process32First(snapshot, pe.addr):
    while Process32Next(snapshot, pe.addr):
      echo pe.szExeFileName

main()

Hi,

thanks it's really working wouldn't have thought of trying it with normal char.
