* Steps performed:
*
* 1) Create the dialog with all the windows we will need
* later. This is done by calling vardlg_build() from
* gic_prompter().
*
* 2) Run the dialog from within gic_prompter(). If the return
* value of the dialog is -1 or IDCANCEL, return an error.
* Otherwise, return success.
*
* 3) From within the dialog initialization code, call
* vardlg_config(), which will:
*
* a) Set all the label strings in all the entry labels and
* the banner.
*
* b) Set the maximum input lengths on the entry fields.
*
* c) Calculate the size of the text used within the banner.
*
* d) Calculate the longest string of text used as a label.
*
* e) Resize each label and each entry within the dialog
* to "look nice."
*
* f) Place the OK and perhaps the Cancel buttons at the bottom
* of the dialog.
*
* 4) When the OK button is clicked, copy all the values from the
* input fields and store them in the pointers we are given.
* Also, set the actual lengths to what we collected from the
* entries. Finally, call EndDialog(IDOK) to end the dialog.
