Bug in nrwin32di.pas - GetSetupError

[moelski]

Hi Roman,

I think there is a bug in the nrwin32di.pas file. GetSetupError uses Integer as Input type. But if i try to compile my app in D2010 I got Error like this: "W1012 Constant expression violates subrange bounds".

If I change the function to this all works fine:

Code Select Expand

function GetSetupError(code:Cardinal):string;

ERROR_NO_SUCH_DEVINST is defined as this:
ERROR_NO_SUCH_DEVINST                    = APPLICATION_ERROR_MASK or ERROR_SEVERITY_ERROR or $20B;

ERROR_SEVERITY_ERROR          = $C0000000;

C0000000 = 3221225472 decimal ....

And integer is from -2147483648 to 2147483647 ...

That wont work ....

Hello

We keep error code as signed integer because in some cases it is suitable to check result on negative value.

Anyway you can always call this function like below:

s := GetSetupError(Integer(ERROR_NO_SUCH_DEVINST));

Hi Roman,

you can always call this function like below:

I never use the function. This was a compilation error in Delphi 2010!

Without my "fix" I wasn´t able to compile my app.

Hello

You confused me :-(

All Delphi versions compile nrComm Lib packages without any errors.
You show me warning. It is not error.

Hi Roman,

You confused me :-(

I´m really sorry for that.

You show me warning. It is not error.

Oh I got errors, too:

These are the Errors and Warnings I got.

Could this be any Compiler Setting in Delphi 2010?
