Greetings.

I am trying to pass a (I think) dchar value to a Windows COM function and it does not work.  Imagine this situation...

dchar test()
{
  dchar val = 0x00000000;
  return val
}

void main()
{
  ...lots of code excluded
  SomeWindowsComCall(test); // this call does not work
  SomeWindowsComCall(0x00000000); // this call works
}

Any idea how I can create a function to be able to return values such as 0x00000000 .. 0x0000FFFF?

Thanks.

It's easier to help if you post an actual, compilable example.  As small as possible. Because the code you posted doesn't show any real possibility of bugs, barring compiler bugs.

Hi Torhu.  Thanks for the reply, but this is an old and working setup using the Juno project.  So, you'll need to install the Juno project,

http://dsource.org/projects/juno

and the Trados 2007 Translation software which I am pretty sure you won't because it is very expensive. :-)  The sample provide is simple and it has no bug.  Don-t forget that I said that I am passing that value to a Windows COM call using Juno, but I think that the returning value from the test function is not really returning 0x00000000 to the COM call.  This is the actual subroutine that returns the value,

dchar GetSourceLanguageEnumaration(char[] lang)
{
 //     *** STaggerF.SourceLanguage Enumeration ***
  dchar sl = 0x00000000;
  lang = std.string.tolower(lang);
  //msgBox(lang);
  switch(lang)
  {
    case "sq", "sq-al": // stfTargetLanguageAlbanian = 0x00000000,
      sl = 0x00000000;
    break;
    case "eu", "eu-es": // stfTargetLanguageBasque = 0x00000001,
      sl = 0x00000001;
    break;
    case "bg", "bg-bg": // stfTargetLanguageBulgarian = 0x00000002,
      sl = 0x00000002;
    break;
    case "be", "be-by": // stfTargetLanguageByelorussian =
0x00000003,
      sl = 0x00000003;

I guess there are no takers. :-)  Ok, I will pose some questions: 1. what type of value is this: 0x00000001? (I thought it was a dchar type, but returning that value as dchar does not work)

2. How can I create a function that would return values such as these? (0x00000000, 0x0000000A, 0x00000000,..., etc.)

thanks for your help.

How about using dchar literals:

  http://digitalmars.com/d/1.0/expression.html#CharacterLiteral

dchar test()
{
    return '\U00000000';
}

I don't think that will work, try this instead:

case "sq": case "sq-al":

Returning a dchar works just fine when I try it, there is probably a bug in your code.

What is the argument type of SomeWindowsComCall?  That's the type you should, and it's probably not a dchar.  Look at the MSDN docs for the function to see what type it wants.
