I am able to instantiate and make calls to a com module
that use only primitive data types, but I simply don't
know what the c# equivalent is for a function expecting
short*. Any help would be appreciated. 3 1631
Hi,
Did you call this function as "DllImport" static function?
If so then you can try e.g.:
[DllImport(...)]
public extern static void MyImportedMetho d(ref short myShort, ...);
But i can not guarantee it will work...
Regards

I tried this, which compiles cleanly, but my app hangs
when I try to run it:
short[] array = new short[16];
foreach ( int i in array )
{
array[i] = 0;
}
fixed (short* dest = array)
{
myobj.SomeFunct ion(19, 1, ref *dest);

There is no equivalent in C#. You can get around this by using unmanaged
code and having a point to a System.Int.32.. .
Or you could change the params in your COM to a short (then you could just
pass in a System.Int.32 w/o using unmanaged code).
This would be more of a "how do I make calls to managed/unmanaged code from
unmanaged/managed code?" question.

Eric

certain amount of floating point work was
approximately.
To attempt to do this I made a program that...

Hi all,
Is it possible to have two connects in the same rexx script to

I have to get data form on DB (with specifics selects and filter out

I know from Wscripts and MS-Sql that you can build just two objects
but I did not see something like that in REXX.
Thanks in advance for your help

Consider the variadic function with the following prototype:
int foo(int num,...);
Here 'num' specifies the number of arguments, and assume that all the
arguments that should be passed to this function are of type int.
(My question has nothing to do with the definition of the function
foo, so don't bother about it.)
If I call the function as:
foo(2,3,4,5,6,7,8);/*More arguments than expected*/

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
