Title: How to find out if an application is running
Question: How can I find out what other applications are running?
Answer:
This is a modified version of Misha Moellner's KillTask() function.
{For Windows 9x/ME/2000/XP }
uses
Tlhelp32;
function IsAppRunning(ExeFileName: string): boolean;
var
ContinueLoop: BOOL;
FSnapshotHandle: THandle;
FProcessEntry32: TProcessEntry32;
begin
Result := false;
FSnapshotHandle := CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
FProcessEntry32.dwSize := SizeOf(FProcessEntry32);
ContinueLoop := Process32First(FSnapshotHandle, FProcessEntry32);
while Integer(ContinueLoop) 0 do
begin
if ((UpperCase(ExtractFileName(FProcessEntry32.szExeFile)) =
UpperCase(ExeFileName)) or (UpperCase(FProcessEntry32.szExeFile) =
UpperCase(ExeFileName))) then
Result := true;
ContinueLoop := Process32Next(FSnapshotHandle, FProcessEntry32);
end;
CloseHandle(FSnapshotHandle);
end;
Example:
procedure TForm1.Button1Click(Sender: TObject);
begin
if IsAppRunning('notepad.exe') = true then
showmessage(' App is running ')
else
showmessage(' App is not running ')
end;
