Hello,

I ' m trying to add reference to the .wsdl file in Visual Studio .NET. The problem is that the memory of the VS. net is increasing upto 250,000 KB and still the web reference is not added. At this point i close the VS. NET and start again but the same thing is happening. Any help will be highly appreciated.

Thanks,

Zee

Ok, so I tried this out and yes, it does sky rocket your memory usage. The eBay API has a lot of parts to it and is fairly large.

Give it some time and it will eventually process everything. On my laptop, it took a few minutes before the API fully resolved.

Yes it did load after few minutes. Now i 'm stuck in another problem. On compiling the code without errors and starting the application, i get the error "Object reference not set to an instance of an object. "

The line highlighted red is :

Line 125: Dim items() As com.ebay.developer.ItemType = buyingResponse.WatchList.ItemArray

Please help.

Please ignore my previous post. I figured out the problem. I was using sandbox url with production keys.

Now, i have another problem :)

I'm getting the following error :

c:\inetpub\wwwroot\WebDesign\WebForm1.aspx.vb(133): Operator '-' is not defined for types 'Date' and 'Date'.

on the line:

timeLeft = endTime - now

Looks like from the error you're attempting to subtract 2 date objects.

Switch to a DateTime object and you'll be able to do that. Something along the lines of

DateTime.Now - start

Does anybody tried this on Visual Studio 2008 ? If I try to build it, the build hangs and takes 100% resources.

On 2005 eveything is OK.

@Victor: This happened to me when I was adding the reference, but it built fine under VS 2008. The ebay API takes a bit to download. That could be it. I think it took me about 15+ minutes when I did it.

The following line of code is giving me a hell of a time:

eBayAPIInterfaceService service = new eBayAPIInterfaceService();

Yields ->

The type or namespace name 'eBayAPIInterfaceService' could not be found (are you missing a using directive or an assembly reference?)

I can't find any resources to explain where/what the assembly is.

@Barry: Are you copying code or did you use the source we provided? If you are just copying code, did you include the web service then at the top of the class include the using block to say You're using the ebay API?

Coding4Fun — Tue, 12 Feb 2008 18:09:30 GMT

@Xavier: No clue why it does that, you may want to contact Alan who wrote the article.

@simster: You're watchlist may be null which may imply you got zero search results from a quick glance.

re: Building a Custom eBay Watch List Using the SOAP API

Barry — Wed, 13 Feb 2008 07:02:36 GMT

@Coding4Fun

I am copying the C# code from the blocks above.

I add the Service Reference from http://developer.ebay.com/webservices/latest/eBaySvc.wsdl

And as far as namespaces, the only 3 I can find are:

using eBay.ServiceReference;

using eBay.Properties;

using eBay;

However I might be missing something, I can't find the eBayAPIInterfaceService object in the entire eBay namespace

I'm using VS 2008, .NET 3.5 if that would make a difference

Coding4Fun — Wed, 13 Feb 2008 21:32:12 GMT

@Barry:

This worked for me.

using ebayTest.com.ebay.developer;

ebayTest is my project name. My web service name is com.ebay.developer too.

This is from a fresh project too.

I just tried the C# version from the download link above.

I am using VS 2008 Express.

I created a New Web site, imported the WSDL file as above.

Copied the source code from the download.

Inserted my AUTHID etc.

When compiling, I get one error on line 11

Line 11 is in Default.aspx.cs

using eBayWebServices;

Error 1 The type or namespace name 'eBayWebServices' could not be found (are you missing a using directive or an assembly reference?)

I left a question a few days ago and it has not shown up.

Any reason why?

re: Building a Custom eBay Watch List Using the SOAP API

Coding4Fun — Sat, 08 Mar 2008 19:27:37 GMT

@Marty: Sorry, I was at Mix 08 and am only now catching up. When you created your web service, what did you name it? That is what your using block for that should be. The author of this article renamed his from the default generated to "eBayWebService"

Do me a favor, type "using " then hit control-space. I'll bet your'll see one of the items in the list be the item that you named your web service.

re: Building a Custom eBay Watch List Using the SOAP API

Marty — Sun, 09 Mar 2008 11:58:42 GMT

HI,

Figured you must have been away.

I am new to all this so be gentle with me.

When creating the Web service, is that when you are doing the

Add Web Reference?

Where do I type the using CRTL-space?

@Marty: Email me by clicking the contact button up on the top and we'll take this offline from this thread. I'll be able to respond quicker then I'll post a response on this thread on how we fixed the issue.

I'll be able to do a screen cast possibly to help out and talk you through it.

I have this error!!

Object reference not set to an instance of an object.

Line 51: ItemType[] items = buyingResponse.WatchList.ItemArray;

HELP PLS T.T

re: Building a Custom eBay Watch List Using the SOAP API

Coding4Fun — Thu, 14 Aug 2008 22:39:36 GMT

@Desperate Student TT: Put in a break point, I bet your WatchList is null.

You'll need to do more defensive coding and verify the buyingResponse.WatchList != null before moving foward

re: Building a Custom eBay Watch List Using the SOAP API

Bun — Wed, 27 Aug 2008 11:34:21 GMT

solved this problem

Line 51: ItemType[] items = buyingResponse.WatchList.ItemArray

replace it with this code

if (buyingResponse.WatchList != null)

{

items = buyingResponse.WatchList.ItemArray;

}

and if (items != null), put this 'if' loop to cover the entire 'add table raw' code
