Has the program been minimized?

[Sina Dehghani]

Hello
I wanted a DLL file to write the name of a program in its input and return 1 in the output if the program was minimized, return 0 if it was not minimized, and return -1 if the program was not opened. Can someone give me this DLL file? or Build this one?

Thanks in advance

This can be done entirely in AutoPlay Media Studio, no DLL needs to be built, no plugins is required. You can use DLL.CallFunction() to query the Windows API function IsIconic() and check if a window is minimized or not. I suggest that you invest some time to learn this program, and show your project where you are stuck, instead of just asking to have things done for you repeatedly.

Hi Ulrich ... I know how to work with Autoplay and my wizard , and I know how to work with the dll.callfunctions function, but I need to be able to see the program that I run in the input (for example iexplorer.exe) Has it been minimized or not? How should I send this information to the user32.dll file?) My problem is here ... Regarding the suggestion you made, I will definitely do the same from now on ... Thank you From your guidance ...

Check the documentation for DLL.CallFunction() and the page I linked in my reply - the function IsIconic() returns an integer and takes a single parameter, which is the window handle. You can get this handle very easily in AutoPlay Media Studio if you put a little effort into this.

I test this code:

result = DLL.CallFunction(_SystemFolder .. "\\User32.dll", "IsIconic", Application.GetWndHandle("iexplore.exe"), DLL_RETURN_TYPE_INTEGER, DLL_CALL_STDCALL);
alert = Dialog.Message("Notice", result, MB_OK, MB_ICONINFORMATION, MB_DEFBUTTON1);

But this code always shows 0, (Whether Internet Explorer is open, minimized, or restored!)

What's wrong?

First, get a list of open programs with Window.EnumerateProcesses(true). This will give you a table of the programs which have a window on the desktop, and also the handle of each window. Find the window you want in this list, and pass the handle to the IsIconic() function.

Also, you need to transform the handle to string to work correctly. This function will return true or false, and takes the window handle as an argument. I defined this function:

function Window.IsIconic(nWhnd)
   local nRes = String.ToNumber(DLL.CallFunction(_SystemFolder .. "\\user32.dll", "IsIconic", tostring(nWhnd), DLL_RETURN_TYPE_INTEGER, DLL_CALL_STDCALL));
   error = Application.GetLastError();
   if (error ~= 0) then
      Dialog.Message("Error", _tblErrorMessages[error], MB_OK, MB_ICONEXCLAMATION);
   end
   return (nRes > 0);
end

Possible use:

local bRes = Window.IsIconic(nWhnd);
if bRes then
   Dialog.Message("", "Window is minimized");
else
   Dialog.Message("", "Window is not minimized");
end

[startup]

result = Window.EnumerateProcesses(true);
for a,z in pairs (result) do
if String.Find(z, "IEXPLORE.EXE", 1, false) ~= -1 then
hndl = a
break
end
end
minimized = DLL.CallFunction("User32.dll", "IsIconic", hndl, DLL_RETURN_TYPE_INTEGER, DLL_CALL_STDCALL);
alert = Dialog.Message("Notice", minimized, MB_OK, MB_ICONINFORMATION, MB_DEFBUTTON1);[/CODE]

Thank's a lot Ulrich ...

result = Window.EnumerateProcesses(true);
for a,z in pairs (result) do
if String.Find(z, "IEXPLORE.EXE", 1, false) ~= -1 then
hndl = a
break
end
end
minimized = DLL.CallFunction("User32.dll", "IsIconic", hndl, DLL_RETURN_TYPE_INTEGER, DLL_CALL_STDCALL);
alert = Dialog.Message("Notice", minimized, MB_OK, MB_ICONINFORMATION, MB_DEFBUTTON1);[/CODE]

this code works correctly! Thank's a lot startup ...
What' s is a and z in the loop?
Why hndl = a ?

[startup]

in this function a is the handle z is the full path of the process after exit the loop a and z becomes nil so it is necessary to store a value in another variable like hndl or any name you like

dude

Declare Function IsIconic Lib "user32.dll" (ByVal hwnd As Long) As Long
If minflag <> 0  (require String.ToNumber) then.

fantastic info Ulrich!
great example startup!

I had no idea DLL.CallFunction() had such potential.

[startup]

yes daviz it has. but that was a simple function. some other functions makes a chalenge

Thank you very much, what about folders ?! It is possible?!

[herrin]

yes using winapi

• WinApi.FindWindow
• WinApi.IsWindowMinimized

[startup]

yes.
you can modify the String.Find in my code to detect folders..
if you remember :-
z = full path.
that means that you can catch folders also.
