Yes, see code below:

// Declare Safe Array Boundary 
SAFEARRAYBOUND sabArgs[1];      // a One Dimensional array
sabArgs[0].cElements = size;    // # of elements in the array
sabArgs[0].lLbound = 0;         // lower bound of array

// Create the safe array
SAFEARRAY FAR* psaArgs = new SAFEARRAY;
psaArgs = SafeArrayCreate( VT_VARIANT, 1, sabArgs ); 
</p>

This is plain wrong. This is not the way you allocate a SAFEARRAY.

For creating 1 dimensional array use the following code

SAFEARRAY FAR* psaArgs =SafeArrayCreateVector(VT_VARIANT, 0, size);

Next call SafeArrayLockData

VARIANT* rgVtVals = NULL;
SafeArrayLockData(psaArgs, (VARIANT**)&rgVtVals);

Then start filling rgVtVals

Finally unlock
SafeArrayUnlockData(psaArgs);

I could not find references to SafeArrayLockData or SafeArrayUnlockData -- did you intend for me to use SafeArrayAccessData and SafeArrayUnaccessData? Those seem to match the parameters.

I'm trying to get the wrox book samples working on my system:

http://www.wrox.com/ACON12H4.asp?WROXEMPTOKEN=160192ZjePJD4tgkFUWWDBumUS&ISBN=1861005644

I tried this at home on XP and at work on 2K and both of my machines produce the same error.
I can't figure out if it's an IIS configuration problem or a code problem (is an assembly requred?)

Can anyone get these samples to work?

I get the following errors when trying to run the Chapter01\CompositeControl.aspx sample:

I had my control in a subdirectory of the web root

\webroot\test\bin\mycontrol.dll
\webroot\test\mycontrol.aspx

That gave me the following error

File or assembly name MyControl, or one of its dependencies, was not found.

To fix it all I had to do was move the \bin dir to the root

\webroot\bin\mycontrol.dll
\webroot\test\mycontrol.aspx

and it worked!

well, if you use xhtml, you can just use the built in xml namespace.

otherwise, you could use com interop to talk to ie.

How do I call a .NET web service?

10-May-02 10:30

Ok, I built a test web service using VS.NET. How do I call the web methods within this service remotely? I want to call the service from a machine with no .NET Framework or IDE installed.

Previously I used Microsoft's SOAP Toolkit to create a web service from an existing com object. It was easy to call the service in vb script by creating a soap client object, all I need to know was the url of the .wsdl file for the service.

But there is no .wsdl file in my .NET web service project. How do I access this service? Please help.

Thanks.

You can use the SOAP toolkit for this also.

You access the WSDL by sticking ?WSDL onto the end of the URL

e.g. http://localhost/webservice.asmx?WSDL

Re: How do I call a .NET web service?

16-May-02 23:53

Thanks. I already tried that. The problem is, SOAP toolkit doesn't seem to be compatible with .NET web service. I always got an error saying something like "SoapPort failed, etc.". Cry | :((

Not sure it this is what you are looking for, but you could invoke web service method(s) via HTTP GET or POST.

If you are familiar with Windows Installer (.msi files) there is a merge module you can use to install the framework.

Unfortunately, I'm not familiar with Windows Installer so I have no idea what you do with it Cry | :((

Wht is the Fastest from vb.net, c# and Managed C++ ?

If I remember correctly Managed C++ is just a smidge faster than C#; C# and VB.NET are about the same after JIT, but VB.NET produces a lot of no-op IL opcodes, which get compiled away.

What is no-op ?

Its an instruction to do nothing.

I'm not sure of Intel processor's but the Sparc requires nop (the sparc name for no-op) before you do any branching (ie goto).
