Calls to Form from outside

Calls to Form from outside

• infoworx

  Hi,
  if you want to set a property in the form you can do something like this in the form:
  
  public: property bool Running
  {
  bool get() { return m_running; }
  void set(bool value) { m_running = value; }
  }
  
  and then in your other function do:
  
  form->Running = true;
  
  if you want to call some function you have some ways of doing this:
  - you can declare a static method (remember that if you do this and you want to access attributes/objects in your class, you'll have to declare them static as well.) In this case you don't need a reference to your form:
  
  ref class MyForm : public Form
  {
  public: static void Test()
  {
  // do something
  }
  }
  
  // and to call the method:
  MyForm::Test();
  
  - you can declare a public method and call it from anywhere if you have a reference to that form:
  
  ref class MyForm : public Form
  {
  public: void Test()
  {
  // do something
  }
  }
  
  // and to call the method:
  form->Test();
  
  Hope this answers your question.

  Looks like an idea! I'll give it a punt.

  On a quick note, what I'm gunning at is to change the picturebox picture outside of the form, I assume the above will work for it, right

  Yes, the best way for you to change it is to make a public method in the form and have a reference to that form (where you want to call the method), then all you have to do is call that method with any parameters you may need to pass:
  
  ref class MyForm
  {
  public: void ChangePictureBox(String imageStr)
  {
  // do your stuff
  }
  };
  
  then when you want to call it:
  form->ChangePictureBox("myimage.jpg");
  
  This should work.
