怎样用命令在ARX程序中加载另一个ARX程序？
高手帮忙给个函数，怎么写？谢谢！

yusongrong

调用arx命令。

ishou

acedArxLoad ( "app");       ----    Load your app.arx
acedArxUnload("app"); -   ----    Unload your app.arx

frankzht

acedArxLoad ( "app"); ---- Load your app.arx
acedArxUnload("app"); - ---- Unload your app.arx
app是arx文件的路径？
acedArxLoad ( "../a.arx");
acedArxLoad ( "c:\a.arx");
我都试过了 都不能加载程序？？？？！！！！

acedCommend("")  是不是直接调用命令？

warmrain

使用以下函数
acedArxLoad ( "app"); ---- Load your app.arx
acedArxUnload("app"); - ---- Unload your app.arx
其中app是你的arx文件名
但是你应该设AUTOCAD的环境变量中的搜索路径

ishou

acedArxLoad ( "../a.arx");      ?[/COLOR]
acedArxLoad ( "c:\a.arx");     Error![/COLOR]
------------------------------------------------------

acedArxLoad ("c:/myDir/a.arx");
acedArxLoad ("c:/myDir/a");
acedArxLoad ("c:\\myDir\\a.arx");
acedArxLoad ("c:\\myDir\\a");
  all  OK.[/COLOR]

如果 设置了 AUTOCAD的环境变量中的搜索路径 C:\myDir, 你可以简单如下：
acedArxLoad ("a");
或
acedArxLoad("a.arx");

======================================
acedCommend("") 是不是直接调用命令？

4. 
   
5. General Access  
   
6. 
   
7. 
   
8. The most general of the functions that access AutoCAD are
   
9. acedCommand() and acedCmd(). Like the (command) function in
   
10. AutoLISP, these functions send commands and other input directly to the
    
11. AutoCAD Command prompt.
    
12. 
    
13. int
    
14. acedCommand(int rtype, ...);
    
15. 
    
16. int
    
17. acedCmd(const struct resbuf * rbp);
    
18. 
    
19. Unlike most other AutoCAD interaction functions, acedCommand() has a
    
20. variable-length argument list: arguments to acedCommand() are treated as
    
21. pairs except for RTLE and RTLB, which are needed to pass a pick point.
    
22. The first of each argument pair identifies the result type of the argument
    
23. that follows, and the second contains the actual data. The final argument
    
24. in the list is a single argument whose value is either 0 or RTNONE.
    
25. Typically, the first argument to acedCommand() is the type code RTSTR,
    
26. and the second data argument is a string that is the name of the
    
27. command to invoke. Succeeding argument pairs specify options or data
    
28. that the specified command requires. The type codes in the
    
29. acedCommand() argument list are result types.
    
30. 
    
31. The data arguments must correspond to the data types and values
    
32. expected by that command's prompt sequence. These can be strings,
    
33. real values, integers, points, entity names, or selection set names. Data
    
34. such as angles, distances, and points can be passed either as strings (as
    
35. the user might enter them) or as the values themselves (that is, as integer,
    
36. real, or point values). An empty string ("") is equivalent to entering a
    
37. space on the keyboard.
    
38. 
    
39. Because of the type identifiers, the acedCommand() argument list is not
    
40. the same as the argument list for the AutoLISP® (command) routine.
    
41. Be aware of this if you convert an AutoLISP routine into an
    
42. ObjectARX® application.
    
43. 
    
44. There are restrictions on the commands that acedCommand() can invoke,
    
45. which are comparable to the restrictions on the AutoLISP (command)
    
46. function.
    
47. 
    
48. Note  The acedCommand() and acedCmd() functions can invoke the
    
49. AutoCAD SAVE or SAVEAS command. When they do so, AutoLISP
    
50. issues a kSaveMsg message to all other ObjectARX applications currently
    
51. loaded, but not to the application that invoked SAVE. The comparable
    
52. code is sent when these functions invoke NEW, OPEN, END, or QUIT
    
53. from an application.
    
54. The following sample function shows a few calls to acedCommand().
    
55. 
    
56. int docmd()
    
57. {
    
58.     ads_point p1;
    
59.     ads_real rad;
    
60. 
    
61.     if (acedCommand(RTSTR, "circle", RTSTR, "0,0", RTSTR,
    
62.         "3,3", 0) != RTNORM)
    
63.         return BAD;
    
64.     if (acedCommand(RTSTR, "setvar", RTSTR, "thickness",
    
65.         RTSHORT, 1, 0) != RTNORM)
    
66.         return BAD;
    
67. 
    
68.     p1[X] = 1.0; p1[Y] = 1.0; p1[Z] = 3.0;
    
69.     rad = 4.5;
    
70. 
    
71.     if (acedCommand(RTSTR, "circle", RT3DPOINT, p1, RTREAL,
    
72.         rad, 0) != RTNORM)
    
73.         return BAD;
    
74. 
    
75.     return GOOD;
    
76. }
    
77. Provided that AutoCAD is at the Command prompt when this function is
    
78. called, AutoCAD performs the following actions:
    
79. 
    
80. Draws a circle that passes through (3.0,3.0) and whose center is at(0.0,0.0).
    
81. Changes the current thickness to 1.0. Note that the first call to
    
82. acedCommand() passes the points as strings, while the second passes a
    
83. short integer. Either method is possible.
    
84. Draws another (extruded) circle whose center is at (1.0,1.0,3.0) and
    
85. whose radius is 4.5. This last call to acedCommand() uses a 3D point and
    
86. a real (double-precision floating-point) value. Note that points are passed
    
87. by reference, because ads_point is an array type.

[B]acedArxLoad ( "app"); ---- Load your app.arx
acedArxUnload("app"); - ---- Unload your app.arx
app是arx文件的路径？
acedArxLoad ( "../a.arx");
acedArxLoad ( "c:\a.arx");
我都试过了 都不能加载程序... [/B]

至少也该写成
acedArxLoad ( "..//a.arx");
acedArxLoad ( "c:\\a.arx");
