Launch deployed application with winopen

Hi, I'm trying to launch an executable (application compiled with AppDesigner) from another deployed application (application compiled with AppDesigner) using the winopen function.

I get the error: Error in validating CTF manifest file.

Is there a solution?

[Jonas]

is this an error of your first application which cannot start the second one, or does actually the second application start and returns that shown error? maybe you can check that? you could also try to use the system() command to start your application

[Simone]

It is an error that prevents the start of the second application.

I'll try to use the system command.

The problem relies on the deployed application since If I try to use winopen to launch the second application (executable) by using the first one from matlab everithing works fine.

[Simone]

Also the sytem command that works correclty from Matlab returns the same error once the application is deployed.

...

function callConsoleApplicationAsync(obj,appWorkingPath,appFileNameWithArguments)

arguments

obj

appWorkingPath

appFileNameWithArguments

end

import System.IO.*

asyncSysProc = System.Diagnostics.Process();

asyncSysProc.EnableRaisingEvents = true;

try

liEmptyProc = addlistener(asyncSysProc,'Exited',@obj.consoleProcessFinished_Callback);

catch ex

disp("Error@callConsoleApplicationAsync save listener handle " + string(ex.message))

end

try

asyncSysProc.StartInfo.CreateNoWindow = true; % true = no cmd windows pops up

asyncSysProc.StartInfo.UseShellExecute = false; % false to enable redirection

asyncSysProc.StartInfo.WorkingDirectory = appWorkingPath;

asyncSysProc.StartInfo.FileName = "cmd.exe"; % use cmd.exe to call any app

asyncSysProc.StartInfo.Arguments = "/c " + appFileNameWithArguments; % add arguments here

asyncSysProc.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;

asyncSysProc.Start();

notify(obj,"ConsoleProcessStartedAsync", WinNetIO.NotifyDiagArgs(string(asyncSysProc.StartInfo.Arguments)))

obj.liAsyncCmd.("P" + string(asyncSysProc.Id)) = liEmptyProc; % id available after start

catch ex

disp(ex.message)

end

end

...

Just copied a function from one of my classes to show how to call any executable asynchronous. This will not block your calling app. If you don't want to use events skip lines for listeners and notification. Be aware of missing class frame for this code snippet.

[Simone]

It is not clear to me what should I pass as first argument.

When I copied the function inside app designer Matlab suggested to replace "obj" with "app". So I did it in the whole function.

The function crashes on execution of "notify(app,"ConsoleProcessStartedAsync", WinNetIO.NotifyDiagArgs(string(asyncSysProc.StartInfo.Arguments)))"

When calling the function I'm passing it

• "app"
• path to the application (e.g. C:\Lavoro\svn\Folder1\Folder2_Name\Folder4_Name
• name of executable (e.g. application.exe)

[Simone]

At the end I was able to run the function from Matlab cutting several parts of code as reported below.

Anyway once I make the executable there is always the error: Error in validating CTF manifest file.

I just want to underline that the applications I'm trying to run from the deplyoed application are other executable compiled with application designer or guide.

function callConsoleApplicationAsync(~,appWorkingPath,appFileNameWithArguments)
import System.IO.*
asyncSysProc = System.Diagnostics.Process();
asyncSysProc.EnableRaisingEvents = true;
try
    asyncSysProc.StartInfo.CreateNoWindow = true;            % true = no cmd windows pops up
    asyncSysProc.StartInfo.UseShellExecute = false;          % false to enable redirection
    
    asyncSysProc.StartInfo.WorkingDirectory = appWorkingPath;
    asyncSysProc.StartInfo.FileName = "cmd.exe";             % use cmd.exe to call any app
    asyncSysProc.StartInfo.Arguments = "/c " + appFileNameWithArguments; % add arguments here
    asyncSysProc.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
    asyncSysProc.Start();
catch ex
    disp(ex.message)
end
end

Sry for the late response. Its rigth the code snippet should be used to create a simple function as you did. This is a fire and forget call and you can call anything from the console. You could call explorer.exe instead of the Matlab executable to debug this part of your code. As you have two AppDesigner apps both are to be compiled and app1.exe needs the path to app2.exe . In the AdditionalSettings section of the AppCompiler you should enable the console output to write debug info via disp cmd for better understanding what happens when.

Check also that the Matlab Runtime version installed matches the compiler version. Another option ist to start the appdesigner app as Administrator to check if this is an priviliges error.
