Detect wether an application is being dubugged or not
<![CDATA[
The following function will detect if the application is being debugged or not. This function will not work on Windows 95.
Behaviour of an application could be changed if run within a debugger, for instance component writers might want their unregistered components to be run in the debugger only.
Answer:
function DebuggerPresent: boolean;
type
TDebugProc = function: boolean; stdcall;
var
Kernel32: HMODULE;
DebugProc: TDebugProc;
begin
Result := False;
Kernel32 := GetModuleHandle('kernel32.dll');
if Kernel32 <> 0 then
begin
@DebugProc := GetProcAddress(Kernel32, 'IsDebuggerPresent');
if Assigned(DebugProc) then
Result := DebugProc;
end;
end;
to use a simple if test can be used
if DebuggerPresent then
ShowMessage('debugging')
else
ShowMessage('NOT debugging');
