I make this code

#include "LoginScreen.h"
. . .
private: System::Void menu_Login_Click(System::Object^  sender, System::EventArgs^  e) {
		LoginScreen^ loginscreen = gcnew LoginScreen();
		loginscreen->MdiParent = this;
		loginscreen->Show();
	}

but i have this error Additional information: Form cannot be both an MDI child and MDI parent.

I change isMdiContainer to true for LoginScreen form.

aaah nevermind :D i change ismdicontainer to loginscreen form, not for menustrip form :D

but one question, how can i make login, and after login to display next form inside this one? when i include form1.h in form2.h and in form2.h include form1.h i get error.

private: System::Void backgroundWorker1_ProgressChanged(System::Object^  sender, System::ComponentModel::ProgressChangedEventArgs^  e) {
		Datapacket^ dp = dynamic_cast<Datapacket^>(e->UserState);
		HlavneMenu^ hlavnemenu = gcnew HlavneMenu();
		MenuStrip^ menu = gcnew MenuStrip(); //i dont know what i need to do with this
		if (dp->val_loginresult == "success")
		{
			hlavnemenu->UserId = dp->val_reader->GetString(0);
			hlavnemenu->Meno = textBox1_username->Text;
			hlavnemenu->mConnection = dp->val_connection;
			hlavnemenu->Show();
			button_prihlasSa->Text = dp->val_reader->GetString(0);
			pictureBox1->Visible = false;
		}
	}
