WARNING!!  This file is overwritten by the UIStyler each time the Styler
file is saved.


      Filename:  pro_design_template.c

      This file was generated by the NX User Interface Styler
      Created by: befree
      Version: NX 3
            Date: 10-27- 6
            Time: 10:04

This template file is overwritten each time the UIStyler dialog is
saved.  Any modifications to this file will be lost.
==============================================================================*/

/*==============================================================================
Purpose:  This TEMPLATE file contains C source and static structures to
guide you in the construction of your NX Open application dialog.
The generation of your dialog file (.dlg extension) is the first step towards
dialog construction within Unigraphics.  You must now create a ugOpen
application that utilizes this file (.dlg).

The information in this file provides you with the following:

1.  Help on the use of the functions, UF_MB_add_styler_actions and
   UF_STYLER_create_dialog in your NX Open application.  These functions
   will load and display your UIStyler dialog in Unigraphics.

   An example of the function, UF_MB_add_styler_actions to associate your
   dialog to the menubar is shown below (Search on Example 1).

   An example of a invoking a dialog from a callback utilizing
   UF_STYLER_create_dialog is also shown below (Search for Example 2).

   An example of a user exit utilizing UF_STYLER_create_dialog is also
   shown below (Search for Example 3).

2.  The callback structure: --- PRO_DESIG_cbs ---
   This structure is VERY important if you have callbacks associated with
   your dialog.  It correlates the dialog items in your dialog with the
   callback functions you must supply.  You should not modify this
   structure since it MUST match up to the information stored in your
   dialog file (.dlg).  Any attempt to do so will cause an error while
   constructing your dialog. If you wish to modify the association of
   your callbacks to your dialog, please reload your dialog file (.dlg) into
   the UIStyler and regenerate your files.
   You do not need to be concerned about this structure, simply pass it as
   an argument to the function, UF_STYLER_create_dialog along with your
   dialog file (.dlg).

   Example 1 displays the actual call you may make for this particular
   dialog.

3.  The empty callback functions (stubs) associated with your dialog items
   have also been placed in this file.  These empty functions have been
   created simply to start you along with your coding requirements.
   The function name, argument list and possible return values have already
   been provided for you.

NOTE:  Each callback must be wrappered with the functions UF_initialize()
   and UF_terminate().

/*-------DIALOG CREATION FROM A CALLBACK HELP Example ----------
If you wish to have this dialog displayed from the callback of
another UIStyler dialog, you should:
1) Make sure that the callback of your UIStyler dialog is
designated as a dialog building callback.
2) Remove the conditional definitions:
#ifdef DISPLAY_FROM_CALLBACK
#endif DISPLAY_FROM_CALLBACK
3) Your callback should issue a call to this function.
4) You should also add the funcitonal prototype to your header file
(pro_design.h) and ensure that the file is properly included.
All dialog files must be located in
   $UGII_USER_DIR/application or
   $UGII_SITE_DIR/application or

因该是你没有入口函数ufusr()，

jufle · 发表于 2010-1-9 19:24

哇这么多看不懂

darkbit · 发表于 2010-1-27 18:42

2lou 楼说的很对
看了你的一大堆代码
就是找不到函数ufusr()或ufsta()
那UG是不知道从何入手的
估计是在按EXE的异步模式搞
不做成同步的DLL动态运行库
又少了MAIN（），编译器在链接时也不知道从何入手
就跳出了
error LNK2001: unresolved external symbol _main
这样的错误
