CallableVEE问题

大家好，自加入ADN专业版以来，我收到了两个VEE6.1更新套件。
我的问题是这个。
如果我在我的一个测试台上安装VEE6.1并加载使用VEE 6.0开发的应用程序，我会遇到任何问题吗？目前，我没有时间评估新的软件版本，但另一方面，我
不想落后。
任何智慧的话？提前感谢Dwayne EnsignEaton Aerospace，Vickers Fluid SystemsJackson，Mississippi ---您目前订阅了vrf：r***@soco.agilent.com要订阅，请发送一封空白电子邮件至“join-vrf@it.lists

  Hello everyone,

Since joining the ADN Professional I have received two update kits for VEE
6.1.  My question is this.  Will I experience any problems if I install VEE
6.1 on one of my test stands and load an application developed with VEE 6.0?
At the present time, I do not have time to evaluate a new software version,
but on the other hand, I don't want to fall behind.  Any words of wisdom?

Thanks in advance,
Dwayne Ensign

像这样：vIn = asVariant（[Param1，Param2]）; lErr = rpcServer.RemoteFunctionName（vIn，vOut）; iAnswer = asInt32（vOut [0]）;这很有趣 - 这正是VeeGateway的工作方式.-

Don't take this as gospel (I don't have version 6 & so can't test this) but
this message would seem to indicate that you must explicitly pack parameters
into a VARIANT array and pass that. Something like this:

vIn = asVariant([Param1, Param2]);
lErr = rpcServer.RemoteFunctionName(vIn, vOut);
iAnswer = asInt32(vOut[0]);

It's funny - this is precisely the way VeeGateway was to work.

肖恩，谢谢你的建议。
我按照你的想法尝试将显式参数打包到aVariant数组中，但我仍然得到相同的错误！
如果我探测传递给函数的数据，以验证数据类型和结构，它看起来正是错误消息告诉我应该传递的内容。几乎看起来VEE主程序没有正确地将Variantdata类型传递给
远程功能，也许是一个bug？
我很乐意让安捷伦有人来验证这个功能.....另一个有趣的事情是我已经验证了我称之为的VEE库。
我已经使用VBScripting测试它来执行callableVEE并访问我的所有库函数！问候，Bill Dyer -----原始消息-----来自：Shawn Fessenden [mailto：shawnf@ameritech.net]发送：9月2日星期二

  Shawn,
Thanks for the suggestion. I tried out the explicit parameter packing into a
Variant array as you outlined but I still get the same error! If I probe the
data being passed into the Function, to verify the data type and structure,
it looks to be exactly what the error message tells me I should be passing.
It almost looks like the VEE Main program does not properly pass the Variant
data type to the remote function, maybe a bug?? I'd love to have someone
from Agilent verify this feature.....
Another funny thing is that I have verified that the VEE library that I call
is OK. I have tested it out using VBScripting to execute callableVEE and
access all my library functions!


Regards,
Bill Dyer

威廉，你不能这样做[使用ActveX客户端/服务器从VEE调用VEE]。
这是安捷伦的官方消息;
显然这是'有点基础'。
你可以做一些事情，比如暴露函数，检查输入和输出类型等，但不能通过参数传递来调用调用位。但它确实可以从其他编程环境中获得良好的工作;
我从Delphi的早期版本和VB中得到了它，它是一块蛋糕。声明说，你必须将参数作为变量数据传递 - 我相信这个媒体上的其他人将能够给出一个更确定的声明
但我知道这是ActiveX接口的一个条件。我认为对于TestStand你必须为每个处理数据类型，返回变量等的测试函数构建一个“包装器”。你看过安捷伦的TestExec SL - 它可以调用VEE程序
希望对你有所帮助。请注意，Mike Watts，________________________________________________________________ Michael Watts，顾问PO Box 92网址：www.PreciselySo.Co.UK埃克塞特，德文电子邮件：MJWC@PreciselySo.Co.UK

  William,
        You can't do it [call VEE from VEE using the ActveX client/server].
That's the official word from Agilent; apparently it is 'something
fundamental'.  You can do things like exposing the functions, examining
input and output types etc. but not the call bit with parameter passing.

It does work admirably from other programming environments though; I have
tried it from an early version of Delphi and from VB and it is a piece of
cake.

The statement stands though, that you have to pass parameters as variant
arrays - I'm sure some others on this medium will be able to give a more
definitive statement but I understand it is a condition of the ActiveX
interface.

I think for TestStand you have to build a 'wrapper' for each test function
which deals with the data types, return variables etc.

Have you looked at Agilent's TestExec SL - it can call VEE programs
out-of-the-box?


Hope that is of some help.


Regards,

Mike Watts
