    Question Dialogs and resources

    I was just wondering if it is possible to make dialog boxes without using resources. All the windows API tutorials I have read always show using resources. And while we're on the subject, how much are resources really needed? I prefer doing things by hand as much as possible, and it would be nice if I didn't need a resource editor to do all this stuff.

    Thanks for any comments.

    Hey,

    You can make dialogs without using resources, but its hard you have to write the code for them in your main cpp file.

    I have not tried this before but if i recall correctly i think that there is some stuff on it in Petzolds book, Programming Windows 5th Edition... i think i read it in there anyway

    Sorry i cant help more

    All ctrls, dialogs and windows can be made on the fly.

    Use CreateWindow() and sepecify the type of ctrl (look in the help for the codes). Remember to cast the HMENU param as the ctrl/dlg ID number

    ie
    #define IDC_MYCTRL 10001
    and in CreateWindow
    (HMENU)IDC_MYCTRL

    The resource editor is good if you have lots of ctrls, on the fly is good for single ctrls or ctrls on a window.

    you can't use createwindow to create a dialog box on the fly!!! that creates a window.. he wants to build a dialog box in memory and use that.

    I have attached a file that is an example of something i made that does what you are looking for... i wanted a function that i could pass an array of strings to and it would create a dialog box that had a radio button for each item, and it would return the index of the button that was clicked... i hope you find it useful.

    building dialog boxes in memory is a pain in the arse!

    What is the difference between a dialog with no ctrls (created on the fly) and a window?

    Except that the dialog is probably not full screen and a child window can't have a menu. (Also the icon in the systray.)

    Dialog resource is, in fact, set of DLGTEMPLATE and DLGITEMTEMPLATE structures. The first in memory is DLGTEMPLATE, which describes dialog window itself. It is followed subsequently by DLGITEMTEMPLATEs. These are for child controls, one struct for each control. After dialog resource script is compiled you get this attached to your exe file. You may choose if to use resource or create template in memory and pass its address to CreateDialogIndirect (). MSDN has good examples on it.

    To Urador again: Dialogs are ordinary windows with some easier management. CreateWindow (I believe) is used internally on dialog creation.

    To novacain: Use CreateWindow if you want your hair got white . Resource editor is the best possible way when creating dialogs.

    That's right - CreateWindow/CreateWindowEx are ultimately called to create dialogs (normally). The system classname for the dialogbox is '#32770'. Never tried using it with CreateWindow though...

    If you are unhappy using a resource editor - presumably GUI - why not just use a text editor if you are looking for more 'control'?

    I'd really have to go along with:
