InstallShield Create a custom dialog box instance __dialog

1. In Dialogs view, right-click All Dialog, select New dialog box (new Dialog)
2. Create a blank dialog box named Mydlg.
3. Double-click the subkey under Mydlg to enter the edit mode of the dialog box
4. Here we add a Hello button. Select the button control and then drag a button control on the interface of the dialog box.
Modify Button property text is hello. Notice the control identifer attribute value here, which we'll use later.
5. Create a new Rul file in the InstallScript view, named Mydlg.url
6. Preparation of Mydlg.url
The contents are as follows:
#define DLG_MYDLG "Mydlg"//mydlg is our dialog box name.
#define HELLOBTN 1301//1301 is the control Identifer property value of our button.

Prototype number Mydlg (BYREF STRING);

function number Mydlg (msg)
HWND Hdlg;
Number NId, Nresult;
Number Ncontrol;
BOOL Bdone;
Begin
Initial dialog box function
if (Ezdefinedialog (Dlg_mydlg,isuser, "Mydlg", 0) = Dlg_err) Then
return iserr_gen_failure;
endif

Bdone = FALSE;
Cycle
while (!bdone)
NId = Waitondialog (DLG_MYDLG); Get a message for a dialog box
Switch (NID)
Case HELLOBTN://If it is hellobtn
MessageBox (msg,warning);
Bdone=true;
Case DLG_ERR:
NId = iserr_gen_failure;
Sderror (NId, Dlg_mydlg);
Bdone = TRUE;

Case Dlg_close:
Sdclosedlg (Hdlg, NId, bdone);

Default
Check Standard handling
if (Sdisstdbutton (nId) && Sddostdbutton (nId)) Then
Bdone = TRUE;
endif

Endswitch;
Endwhile;
End

Added is #include "Mydlg.rul"
And our custom dialog box. The rest of the code is automatically generated.
