" A good example of that is where I have 3 or 4 panels on a single form and I want one keypress event to process every keypress on the form itself... as opposed to having individual keypress events for each panel. "
Any WinForm has a KeyPreview property that will cause all key events on child controls to occur on the Form first before occuring on the control. "What I want is something that loads the child form within the parent form... and I don't want to have to control it. I figured that using an MDI form but only allowing the child forms to open once copy of the form, would sort of give me the results I am looking for. " There are several ways to go about this for an MDI application. In general if you need only one type of form open at once, you need to have a dictionary keyed from the "type" of form you're using to generate and the value being the form instance itself. Here's is one example you might find useful. You didn't specify a language so I'll use C# here: private Dictionary<string, BaseForm> _forms = new Dictionary<string, BaseForm>(); /// <summary> /// Creates an instance of the specified form if it's not already present in the list. /// </summary> /// <typeparam name="FormType"></typeparam> private BaseForm CreateForm<FormType>() where FormType: BaseForm { BaseForm form = null; if (!_forms.ContainsKey(typeof(FormType).Name)) { form = new FormType(); } else { form = _forms[typeof(FormType)]; } //Additional code goes here... //Return the form. return form; } You can use this method to create a new form, or return you one that already exists without having to know if it does or not.

I'm having some problems using the KeyPress event in various winForms. I want to have a common keypress event set of code that will process of the F-Key presses. I have the code worked up but I am finding that on different forms the event doesn't fire. For example, when I added a tabbed control to the page, the form's keypress event stopped firing. However, the tabbed control's keypress event is working. So I just moved the code from the form's keypress event to the tabbed controls keypress event. The problem here is that I only want one type of keypress event for ALL of my forms and sometimes I cannot find a keypress event that actually works. A good example of that is where I have 3 or 4 panels on a single form and I want one keypress event to process every keypress on the form itself... as opposed to having individual keypress events for each panel. Any ideas how I could build a keypress event that would work on all forms regardless of what's on them? Just one keypress for everything on the form. You figure that the form_keypress event would be what I am looking for. However, it doesn't always work. Am I missing something? Also, I am trying to use an MDI parent/child form to create an IDE like UI for this application. The problem here is that MDI isn't exactly what I need because you can only create ONE instance of each form. So I do not want to create the traditional multi-document interface like used in something like Word or Excel. What I want is something that loads the child form within the parent form... and I don't want to have to control it. I figured that using an MDI form but only allowing the child forms to open once copy of the form, would sort of give me the results I am looking for. What I would like to know is if there is another way to handle this? What I would like is something like how the .Net IDE works. You have the parent form with child forms, but you can only open one instance of each child form at a time... as opposed to multi like you could in Word or Excel. How would you recommend this sort of IDE be built? Should I be using the MDI parent/child forms? Is there an easier way to build IDEs like this? =================================== This list is hosted by DevelopMentor(r) http://www.develop.com View archives and manage your subscription(s) at http://discuss.develop.com
