Paypal Payment Data Transfer (PDT)

2011-08-07T05:23:00.000-07:00

Before talking about PDT, the easiest way to enable paypal integration, use the code below.

<input type="hidden" name="cmd" value="_xclick" />
<input type="hidden" name="business" value="test@test.com" />
<input type="hidden" name="return" value="paymentdone.aspx">
<input type="hidden" name="cancel_return" value="http://cancel.aspx">
<input type="hidden" name="currency_code" value="SGD">
<input type="hidden" name="custom" value="1188967">
<input type="hidden" name="item_name" value="12 months Membership" />
<input type="hidden" name="amount" value="10.00" />
<input type="submit" value="Buy!" />

After user make payment through payment, user is required to click 'Return to seller website'.

If PDT is enabled under your seller profile, it will return tx (txn id) to your designated return page.

The page return from Paypal will contain the parameter in query string as below.

http://YourReturnWebsite.aspx?tx=0YB16486MY080364E&st=Pending&amt=10.00&cc=SGD&cm=1188967&item_number=

cm is the custom parameter that you put in your 'buying' page. This is useful to identify the transaction your customer made.

With the tx (txn id) given, you can do a http post to paypal again to retrieve the txn details, and the response you can get is something like below, which contain the detail of the transaction.

SUCCESS mc_gross=10.00 protection_eligibility=Partially+Eligible+-+INR+Only address_status=unconfirmed payer_id=NWDEUYU4YEE32 tax=0.00 address_street=1111 payment_date=04%3A57%3A24+Aug+07%2C+2011+PDT payment_status=Pending charset=windows-1252 address_zip=11111 first_name=Tan address_country_code=SG address_name=Henry+Tan custom=1188967 payer_status=unverified business=sales_biz%40email.com address_country=Singapore address_city=Singapore quantity=1 payer_email=test1_1312687433_per%40email.com txn_id=0YB16486MY080364E payment_type=instant last_name=Henry address_state= receiver_email=sales_1312687640_biz%40marketdata360.com receiver_id=L6DQ94PEGKY5S pending_reason=multi_currency txn_type=web_accept item_name=12+months+Membership mc_currency=SGD item_number= residence_country=SG receipt_id=3184-4081-1163-0163 handling_amount=0.00 transaction_subject=1188967 payment_gross= shipping=0.00

The limitation for PDT is that, you wont receive these information if user didnt click on 'return to seller website'

Extraordinary experience jquery + colorbox + uploadify

2011-05-05T22:36:00.000-07:00

A simple control which allows you to upload multiple files using uploadify and display the control with colorbox in ASP.NET, can be a learning of lifetime for you, because you need to know deeply what's going on behind server and client.

Strange behaviour 1:
Imagine you display you display the image via colorbox on custom aspx page (display.aspx), if you include RadScriptManager, you will find that your image galllery page (gallery.aspx), the uploadify couldnt trigger upload.aspx after you upload your files. I suspect it is due to the 'funny' generated html code by asp.net.

Multiple upload controls

2011-05-04T18:47:00.000-07:00

Uploadify might be your best choice, which use jquery + flash.

Some points to note on this control. If you use it in pages need authentication. Remember to remove security access for your upload.aspx, else you will encounter http 302 !!!!

public string testFunction(string test)
{

Expected Header
User-Agent: Fiddler

worldpay integration

2010-10-14T03:14:00.001-07:00

The tricky part of the worldpay integration is about the redirecting. There is no way for you to specify where to redirect the user to a destinate page when the payment is completed.

Instead worldpay use the concept of proxy calling, which will call you page indirectly, in fact it is the Payment Response URL that you specify in installations after you login to worldpay page.

IF you didnt set the checkbox for [Enable the Shopper Response], user will not see the redirect.

In conclusion, the trick is to use point the Payment URL to PAGE A, then in PAGE A you include

< meta http-equiv=' refresh ' content=" 0 ; url = http://YOUR FINAL URL" / >

You will show you thank you message in your final URL.

Last point is to make sure you captured the transaction information that pass to you from worldpay in the Payment Response URL page.

Refer to this article http://harrybailey.com/2010/02/worldpay-response-url-shopper-return/.

unable to retrieve textbox value in server side when textbox is set readonly

2010-04-28T02:08:00.000-07:00

One of the common UI design is to have a couple of textbox and you might want to prevent it from user modifying the value. And the easiest wayout is to set the textbox as readonly or disabled.

Unfortunately, you wont be able to get these 'disabled' or 'read-only' textbox value from server side.

One of the workarounds is to set the readonly condition during runtime instead of design time in asp.net page.

txtbox1.Attributes.Add("readonly", "readonly");

Page load event is fired twice with user control

2010-04-28T02:02:00.000-07:00

One very strange behaviour that i noticed is that, page load event is fired twice. It started with page load and then followed by postback.

What I have:
1. Ajax Page
2.User Control
3.Asp.net C# page

After going through many testing and debugging, i realize that after setting the auto event wire up as false, everything is back to 'normal'.

To know which control trigger the postback, apart from using ___EventTarget to track, refer to this post, it contains a more comprehensive approach.

Page AutoEventWireup="false"

Animated scroll to anchor/id function with jQuery

2010-04-22T01:59:00.000-07:00

This feature is useful especially when you need to maintain the page position after browsing from other pages.

A quick win will be using anchor in the url, but the catch is if you are using controls like telerik grid ajax postback, the anchor point #XXX in your url will be subtracted and you won't be able to do what you want.

One more point is that it is good to use this function in $(document).ready(function ()) instead of pageLoad() so that it only move to your position once when page is loaded not ajax postback.

$(this).addClass("buttonZoneShow");

},

2010-02-25T01:35:00.000-08:00

Checkout this article to learn how to use VS Test Project to apply test driven development methology in your project. This article highlights the details on data driven test case

One point to note is that, it is possible to keep your test data in database, which is very useful in doing testing, instead of coding on the logic for your test data, you can leverage on the framework.

[TestMethod]
[Owner("Mark Michaelis")]
[TestProperty("TestCategory", "Developer"),
DataSource("System.Data.SqlClient",
"Data Source=.\\SQLEXPRESS;AttachDbFilename=\"";Integrated Security=True",
"LogonInfoTest",
DataAccessMethod.Sequential)]

Error : Sequence contains no elements when you execute query that return null

2010-01-20T07:10:00.000-08:00

In this statement if Trans.param1== param1Value returns nothing, you will hit the error above.

Class1 objClass1 = _db.Class1.First(Trans => Trans.param1== param1Value);

To prevent this, you need to use 'FirstOrDefault' instead

Class1 objClass1 = _db.Class1.FirstOrDefault(Trans => Trans.param1== param1Value);

ashx

2010-01-15T16:27:00.000-08:00

Just discover what is ashx in asp.net, it is nothing but the httphandler that we used in MOSS.

Creating a new ashx, is actually creating a class that inherit from IHttpHandler. Instead of loading xml from page load event in typical asp.net web form, ashx could be the best option for you to do the same tasks.

Example,

public void ProcessRequest (HttpContext context)
{
context.Response.ContentType = "text/xml";
context.Response.ContentEncoding = System.Text.Encoding.UTF8;

string sXml = BuildXMLString(); //not showing this function,
//but it creates the XML string

context.Response.Cache.SetExpires(DateTime.Now.AddSeconds(600));
context.Response.Cache.SetCacheability(HttpCacheability.Public);
context.Response.Write( sXml );
}

How to change theme when new site is created

2009-09-08T05:32:00.000-07:00

Some of you have this requirement to create a new theme for your customer. And obviously this theme will be used automatically if a new site is created.

One of the stupid way is to include the step to change the theme as part of the operating mannual, but let me show you the tricks.

If you understand the concept of branding on how to change the .master page, you will find this theme changer feature is very similar.

What you need to do is to :
1. Create a new theme (i.e. NewTheme) and put it in 12hive\ Themese folder
2. Create a new .vb file which inherit SPFeatureReceiver and override FeatureActivated method to include the below coding.

Dim objWeb As SPWeb
objWeb = properties.Feature.Parent
objWeb.ApplyTheme ( " NewTheme " )
objWeb.Update()

3. The above is to ensure that newtheme is being switched when the code is feature is activated.
4. Compile it with strong name and deploy to GAC.
5. Package this .dll as feature
6. Locate the onet.xml for site template that you have 12hive\template\sitetemplates\SITE NAME\xml
7. locate to include the feature ID which you have created earlier.

The idea of this theme changer is very similar to branding.

Good Architect for DAL

2009-07-08T08:42:00.000-07:00

I came across a very structure way to populate data from database back to object class.

After we retrieve data from database, typically we will have a datareader object. We can leverage on the method below to convert dr value to match with the data type in object class.

protected T GetDataObjectValue(IDataReader dr, string columnName)
{
int i = dr.GetOrdinal(columnName);
if (!dr.IsDBNull(i))
return (T)dr.GetValue(i);
else
return default(T);
}

Next, we can build a function to load the value into object class like below:

obj.ID = base.GetDataValue(dr, "ID");

If required, we can add the object into a object List.

Infopath Best Practice

Infopath Deployment Best Practice

infopath limitation

2009-07-02T06:58:00.000-07:00

It is very important to understand the limitation of infopath 2007. From high level, web based infopath is very powerful but it comes with several limitations.

No native write to SQL databases. The ease of use of establing an ADO connection to SQL or Access, and being able to query and write back to a database is lost. Instead you will probably need to talk to the DB via a web service.
No roundtripping for cascading picklists. Something I do all the time is have one picklist be a filter for another picklist. Common example, pick a state, which then filters the city field dropdown. Can't do that in a web form.
Summary list of controls that aren't supported in web forms:
ComboBox,Multiple-Selection List Box
Master/Detail,Bulleted, Numbered and Plain List
Picture ,Ink Picture ,Vertical Label
Scrolling and Horizontal Region ,Horizontal Repeating Table
Choice Group ,Repeating Choice Group
Choice Section ,Repeating Recursive Section
ActiveX Controls

Refer to this article for more details, MSDN article.

With this limitation, this shows you how to perform debugging.

How to MASS remove item in list

2009-06-30T22:17:00.000-07:00

The typical answer is to do a looping to remove all items one by one. This required multiple call to the server. Check out the following approach

private static StringBuilder BatchDeleteCommand(SPList spList)
{
StringBuilder sbDelete = new StringBuilder();
sbDelete.Append("< ? xml version=\ "1.0\" encoding=\"UTF-8\"?>");
string command = "" + spList.ID +
"< / SetList>{0}< / SetVar>Delete< / SetVar>< / Method >";

foreach (SPListItem item in spList.Items)
{
sbDelete.Append(string.Format(command, item.ID.ToString()));
}
sbDelete.Append("");
return sbDelete;
}
