The fifth google result for asp.net calendar control Populating Form Inputs Using the Calendar Control[^]. Learning how to use search engines will make learning asp.net much faster and easier.

Ajax tool kit provides the nice calender extender controls to solve your problem.
You can see the sample example on

Accessing SOAP message response elements

Hi,
I have created a SOAP Web Service client (as a proxy class). I am able to successfully send and receive a SOAP message to the SOAP Server. Here's where my hickup is though: when i receive back the response from the SOAP server, I can access most of its elements but the one called "errors". Here's the raw XML that is sent from the soap server:

<soap-env:Envelope xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/">
<soap-env:Body>
<pxb2b:register-user-reply xmlns:pxb2b="something">
<pxb2b:datetime>2010-03-31T18:08:55.938</pxb2b:datetime>
<pxb2b:px-transaction-id>0</pxb2b:px-transaction-id>
<pxb2b:response-code>400</pxb2b:response-code>
<pxb2b:errors>
<pxb2b:error code="already_registered" field="error">This card is already registered</pxb2b:error>
</pxb2b:errors>
</pxb2b:register-user-reply>
</soap-env:Body>
</soap-env:Envelope>

Here's how I try to do it:
First I get the response object (which is part of the proxy class)

Dim pxRegUserReply As registeruserreply
pxRegUserReply = pxRegUserBinding.registeruser(pxRegUserRequest)

Through this pxRegUserReply object I can access all of the XML elements, e.g. pxRegUserReply.responsecode, pxRegUserReply.pxtransactionid and so on.

The problem is that when i try to do this pxRegUserReply.errors, I get a zero length element.
and pxRegUserReply.errors.Length returns 0.

Can somebody explain what I am doing wrong? I am kinda new to VB, so it may be something very simple.

Thank you for your input!

Learning Test Driven Development in VS 2008 - ASP.NET

Hello,
I am just fresh new learner of Test Driven Development in ASP.NET with Visual Studio 2008. So far everything looks ok, but I have a question regarding the following snippet:

[TestMethod]
     [HostType("ASP.NET")]
     [UrlToTest("http://localhost:49161/Default.aspx?demoParam=Hello")]
     [AspNetDevelopmentServerHost(@"D:\My Projects\AspNetTDD1\AspNetTDD1", "/AspNetTDD1")]
     public void CheckQueryStringParsingAtLoad()
     {
         Page page = TestContext.RequestedPage;

         // need to manually invoke the Page_Load method.
         PrivateObject po = new PrivateObject(page);
         po.Invoke("Page_Load", page, EventArgs.Empty);

         Label label = page.FindControl("Label1") as Label;

         if (label != null)
             Assert.AreEqual("Hello", label.Text);
     }

As you can see, the port number 49161 after the localhost, it changes every time I build the application or if I restart the server. So, if I have 100 test cases, I will have to change the url to every method every time it changes. Is not there any other way to set that url programmatically ? Also, I have a complain about the attribute AspNetDevelopmentServerHost. Why should I Hard Code the path to the application folder ? I want it to be portable so that I can change the folder structure any time? So, I would like to set that Application folder programmatically too.

Can you give me any idea please ?

Regards

I haven't used it, but I think you should use test run configuration file[^]. It allows you to specify all the settings rather than using attributes and hard coding it.

BTW, what are you testing in the example provided? Just verifying a label exist?

Hi,
Thanks for the reply. Looks like, I need to read a lot to set the attribute dynamically. I have no idea why Microsoft made it so hard. I found another library named, NUnitASP which could allow me to do test driven development where I can set the url dynamically. but unfortunately, the library is so old, it does not work anymore, but Microsoft can learn from this small open source library.. it is frustrating anyway.

By the way, I was testing a label value shows an expected value after a button click. Smile | :)

Yeah, it is a simple test for demonstration.

In TDD, views are usually not tested as you test other parts. You have to create your view as thin as possible. This will allow you to test all other business logic totally isolated from view and view will have just few getters and setters. Read up on patterns like MVP to know more about doing so.

Just a word of warning Smile | :)

BTW, all these TDD concepts has got a tendency to trap you into excessive layering and abstractions. You will end up with creating new abstractions just for the sake of testing it and the output will be code which is tough to debug and will have full of obscure bugs. Finding a balance between what to test and what not to test is bit tough and can be learned from practice. So I'd suggest you to maintain simplicity and avoid unnecessary abstractions just for testing.

Navaneeth

Hi Navaneeth,
Yes, thats what I see. In order to test, I need to add many layers of complexity. Maybe we need to switch to ASP.NET MVC. But, so far I found in MVC, I will have to forget the Designer, rather I will have to use a bunch of HtmlHelper static methods to generate my page. What a yakeee idea. To my point of view, a Website is really UI driven. I like to use ASP.NET Controls in Design time, add property values and handle Events from the VS designer. Anyway, my brain is getting cluttered with so many technology clumsiness Smile | :)

I think, within next few years, ASP.NET MVC will have much designer support and I am jealous with those developers who will start learning ASP.NET at that time and get readymade stuffs Smile | :)

Try WatiN[^]instead.

If you want to get going quickly I would also download WatiN Test Recorder. The latter is a bit buggy but it's good for giving you a rough starting point. Plus you should combine with IE dev tools. to get control IDs.

Although Watin 1.0 has been out for ages and Watin 2 has been in beta for ages the mailing list is very active and very responsive. WatiN is a solid library.

Selenium[^]is another possibility but I've not tried it.

Have a look at the ASP.NET project properties. There's a setting for fixing the port number.

Store repeater value in session variable

HI i have successfully created a connection string
and the rest of the commands are as follows

Dim cmd As New SqlCommand(sql, SQLConn)
cmd.Connection.Open()
Repeater1.DataSource = cmd.ExecuteReader()
Repeater1.DataBind()
cmd.Connection.Close()
The above code works fine..

My doubt is that how to i get to store all rows of a column returned by a Repeater in a session variable....

Can do tht using a SQldatareader as:
Session("SessionName")=readerobj("uid")

Repeater doesn't have rows or columns.

What are you trying to achieve? Why do you want to keep the repeater generated code in session? Are you trying to do some sort of caching?

Navaneeth

Hi... im trying to emulate a simple captcha control. I wanted to distort a text generated by Graphics.DrawText() method. Or is there a better way to make this? Thanks a lot.

Without using GDI+? I don't think so.

Have you considered using ImageMagick? We use it for a number of similar processes. Fred's ImageMagick Scripts contains a captcha sample script: http://www.fmwconcepts.com/imagemagick/captcha/index.php[^]

I have not used that specific captcha technique I mentioned, but I do use ImageMagick (IM) with ASP.NET. I have a pretty basic article on COde Project about generating previews from uploaded images with IM, Using ImageMagick to Create Previews and Thumbnails from Uploaded Images[^]. This is similar to what you are trying to do by creating a dynamic image and return it to the browser. The key method is CallImageMagick(string fileArgs). You pass your argument, such as the captcha command, which defines the distortions and the output path of the file. The random string used to create the captcha using IM would be stored and used to verify the user response to the captcha challenge.

IM is easy to download and install. The latest update which I just installed on our server was "ImageMagick-6.6.0-7-Q16-windows-dll.exe". Make sure to check the last install option - "Install ImageMagickObject OLE Control...", so that MagickCMD.exe will be installed. You will need to provide the path to this file in your code; see my article.

There are several other good articles on CodeProject about using IM with ASP.NET. That is where I learned about it.

Regards,

Gary

form for ordering pizza

Please help me with this assignment.

Use ASP.NET to write a web page with a form for ordering pizza. When loaded, the page should appear as shown in appendix 1. To avoid clutter, use only 3 options for each select element (for example, use only months 07, 08, and 09 for the expiry date). Be sure to preserve alignment of items. The Submit button sends all the user inputs to URL http://www.pizzapronto.com/orders. The Reset button resets the form.
