在SERVER一端，想RUN一个EXE文件。
比如说，用户CLICK一个BUTTON，SERVER就LOAD一个EXE进行一系列的计算。怎么才能LOAD
这个执行文件？我用了SHELL，但是并不能真正的LOAD出来EXE。

System.Diagnostics.Process process=new System.Diagnostics.Process();
process.StartInfo.FileName = "xxxx.xxx";
process.StartInfo.WorkingDirectory = this.Server.MapPath(this.
TemplateSourceDirectory);
process.Start();
===============================
I used a batch file.. :D

Thanks.
你有没有现成的例子，给我看一看？
我依照你的方法试了试，好象和用SHELL的结果是一样的。主要是要画个图，传回CLIENT
一端。我现在把图存下来，但是这样RUN的EXE存下来的图老是写着“Drawing Failed”，
单独RUN那个EXE就没问题，图好好的。

也有可能是画图的问题。图是生成了一个FORM，把图放在FORM上，这个不知道是不是会影
响？另外，画图的SOFTWARE是以前的COM DLL，不过EXE是在。NET里面写的，图本身是画
得出来的。

Does your drawing exe need to access any other resources that are not
accessible from the account .net runs from? If it works when you log in and
run it, but doesn't from .net, it's usually because of different environments
or access rights.

good one, we have serious problem for some components when accessing from
asp.net pages... it's just unstable, and usually part of operation will
fail due to lack of credential, so far some one here just wrote some
wrapper to call those components through a hosted environment, with
credential which can be set for the hosted wrapper in component service.. hehe

thank both of you.
Access right was a problem which i considered and solved at the very beginning.
I do have other resources and ASPNET is a strict user by default.
Right now, it looks it is a problem of display. EXE can't pop out(st, you might
not remember it exactly), which causes my program can't save the graph
correctly.

check ProcessStartInfo.CreateNoWindow,
the default is false.
I saw the window back in the old days, maybe it was .net 1.0, which has
not that much security as .net 1.1... probably .net 1.1 suppressed this
window thing....
the user accesses your ASPNET application might be anonymous, I think...
at least that's what caused the problem here...

Does the drawing program actually pops up a Windows window and draw in there?
Maybe change that to render on an in-memory image or something so it doesn't
have to paint on the screen? ;-)

yeah, our graphics package is not good (actually very bad, quinn -curtis 3.0).
there is no exposed function being able to have an image saved in the memory.
Anyway, we'll still have to use this package at least for a while.
