How are you drawing said button?
What type of login system have you implemented/need to implement?

thank you guys for the reply. i have a txt file with some user credentials eg. admin and user. should admin login he will have say 3 buttons available, should user login he should have say only two buttons available. I have commented out where i am trying to call the form which should have the said button disabled. Here is some of my code. thanks for your assistance.

for(int i = 0; i < Count; i++)
		   		 if ((strUser == U[i].Name) && (strPword == U[i].Password))
				 {
					 Accept = true;
					 break;
				 }
				 if (Accept)
				 {
					 MessageBox::Show("Welcome to ...", "Welcome", MessageBoxButtons::OK, MessageBoxIcon::Information);
					 this->Hide();
					 MainLect2GUI ^mForm = gcnew MainLect2GUI();
					 mForm->ShowDialog();
				//	 mForm->btnViewLect->IsDisposed();
					 this->Visible = true;
					 txtUser->Clear();
					 txtPass->Clear();
					 }
		
				 else {
					 MessageBox::Show("Invalid attempt","Error", MessageBoxButtons::OK, MessageBoxIcon::Information);
					 if(txtUser->Text != "")
					{
						txtPass->Text = "";
						txtPass->Focus();
					}
					else
					{
						txtUser->Text = "";
						txtUser->Focus();
					}	
					 Count++;
					 txtUser->Clear();
					 txtPass->Clear();
				     txtUser->Focus();
					 } 
				 while(!Accept)
				 {
					 if(Count == 3){
						 MessageBox::Show("Too many failed attempts","Error", MessageBoxButtons::OK, MessageBoxIcon::Information);
						}
					 break;
				     this->Close();
				 }
