UnicodeDecodeError: 'ascii' codec can't decode byte in position

possible solution will be to eliminate non-ascii characters, here is function in python

import string
def n(self,myStr):
    return filter(lambda x: x in string.printable, myStr)

sqlite3.OperationalError: Could not decode to UTF-8 column

to get rid of this error add following line after opening connection:

db_connection = sqlite.connect('my.db')
db_connection.text_factory = str

The certificate for omega.contacts.msn.com could not be validated. The certificate chain presented is invalid.

2010-11-24 Update: Please download latest version of Pidgin, that has this problem fixed , no additional steps required.


Here are 3 ways to fix this error:
sorted from easier to harder,solution #1 works in most cases .
If it doesn't you can try solution #2 or solution #3 , this will fix problem for sure.

solution #1(easiest, try it first )

remove file :
c:\Documents and Settings\[your-username]\Application Data\.purple\certificates\x509\tls_peers\contacts.msn.com

In Win 7 the path is: C:\Users\[UserID]\AppData\Roaming\.purple\certificates\x509\tls_peers

or for linux :
~.purple/certificates/x509/tls_peers/contacts.msn.com
and Pidgin will load latest certificate.

Update: it also can be fixed by deleting certificate from Pidgin menu Tools/Certificate.


Solution #2: (if #1 is not working)

a.Download this file,

b. delete the .txt extension, so that you end up with omega.contacts.msn.com only,

c. copy the file to your c:\Documents and Settings\[your-
username]\Application Data\.purple\certificates\x509\tls_peers folder


Solution #3: (similar to solution #2 but importing certificate directly from omega.contacts.msn.com)

a. open https://omega.contacts.msn.com/

b. On the URL bar, click on the security lock (usually just in front of the URL). Click on the certificate information.

c. Go to the Detail tab and click the “Export” button. Save the file as “omega.contacts.msn.com” (without the quotes).




d. Copy and paste this file to
“/home/your-username/.purple/certificates/x509/tls_peers/omega.contacts.msn.com”. When prompted, select “Replace” to replace the existing file.That’s it. Open your Pidgin and the SSL certificate error will be gone.

The element has invalid child element. List of possible elements expected: .

Error:The element 'Schedule' has invalid child element 'RecurrenceRule'. List of possible elements expected: 'Occurring'.

To fix this XSD problem:
Theory:

XSD gives 3 indicators: <xs:all>, <xs:sequence>, and <xs:choice>.

xs:all allows the specified child elements to appear (or not) in any order in the containing element... except they can only appear once.

xs:sequence requires the specified child elements to appear in the order they are given

and xs:choice requires that only one of the specified child elements appears, but it can appear any number of times.


so I just changed tag from <xs:sequence> to <xs:all> and it fixed problem.

orginal code

   
<xs:element name="Requirement" minOccurs="0">
<xs:complexType>
  <xs:sequence>
    <xs:element name="Name" type="xs:string" minOccurs="0" />
    <xs:element name="Duration" type="xs:int" minOccurs="0" />
    <xs:element name="Occurring" type="xs:int" minOccurs="0" />
  </xs:sequence>
</xs:complexType>
</xs:element>

changed code

   
<xs:element name="Schedule" minOccurs="0">
<xs:complexType>
  <xs:all>
    <xs:element name="Name" type="xs:string" minOccurs="0" />
    <xs:element name="Duration" type="xs:int" minOccurs="0" />
    <xs:element name="Occurring" type="xs:int" minOccurs="0" />
  </xs:all>
</xs:complexType>
</xs:element>

C# bind dropdown to enum

For example we have enumeration Enum1 and want to bind ddEnum1.
here is how to do it in directly into html page , when GetEnum1 is function in codebehing , that will be getting SelectedValue for every record object (passign by parameter)

     
<asp:TemplateField HeaderText="Type" ItemStyle-Width="5%" ItemStyle-Wrap=False HeaderStyle-HorizontalAlign=Center HeaderStyle-Wrap=False ItemStyle-HorizontalAlign=Center>
	<ItemTemplate>
				  <asp:DropDownList id="typeDropDown" runat="server" Width='150'
					DataSource="<%# Enum.GetNames(typeof(myEnum1)) %>"
					SelectedValue='<%# GetEnum1(Container.DataItem) %>'
					OnInit="InitDropDown" />

	</ItemTemplate>
</asp:TemplateField>

here is how to do it in codebehind

       
    private void Page_Load(object sender, System.EventArgs e)
    {
         if(!IsPostBack)
         {
            ddEnum1.DataSource = Enum.GetNames(typeof(Enum1));
            ddEnum1.DataBind();
         }
    }

      private void ddEnum1_SelectedIndexChanged(object sender, System.EventArgs e)
      {
       Enum1 selectedEnum1 = (Enum1)Enum.Parse(ddEnum1.SelectedValue);
      }

remove space above table in Blogger.com

when you publishing table on Blogger.com you will have a bunch of space above table.
Because Blogger.com adds a

<br />

tag for each new line
To avoid this, add this before HTML for your table:

<style type="text/css">.nobrtable br { display: none }</style>
<div class="nobrtable">

show hide javascript

Here is sample how to show hide, control in asp.net/javascript
let say we have ddBerechnung control and we have to hide controls when this dropdown has value 'identisch'

server side will have this :

         
protected override void OnPreRender(EventArgs e)
{
	ddBerechnung.Attributes.Add("onChange", "ShowHidePercentField(this)");
}

and aspx will have this javascript:

         
function ShowHidePercentField(cb){
                var selIdx = cb.selectedIndex;
                var newSel = cb.options[selIdx].text;
                var textBox=document.getElementById('<%=txtBerechnung.ClientID%>');
                var Runden= document.getElementById('<%=ddRunden.ClientID%>');
                var RundenSpan= document.getElementById('RundenSpan');


                if (trim(newSel)=='identisch'){  ///
                        textBox.style.display="none";
                        Runden.style.display="none";
                        RundenSpan.style.display="none";

                }else{
                        textBox.style.display="";
                        Runden.style.display="";
                        RundenSpan.style.display="";

                }

        }

///.... at the end of control

H1B to COS B1/B2

Q

1. On H1B I797 & I-94 both valid till July 31,2009. Used 3 years of H1.
2. Last day on job May 22. Last pay I will get on 06/06/2009
3. Company said it will not file for H1 extension and will not revoke ( few weeks only).
My questions now-
1. Can I apply for COS to B1/B2 Efile now since I have car to sell and other stuff?
2. If I get a job before B1/B2 approval, how do I continue on H1 ?I assume my employer files for H1 extension.
3. If I get a job AFTER B1/B2 approval and also after expiry of H1 ( July 31), how do I get back onto H1?
4. If I go back to India,after expiry of my current H1, how can I revive this H1 with the current employer or New Employer?
5. If I apply for 2010 quota, can I be counted against old H1? or do I get new H1?( meaning 6 years?)

A.

1. Can I apply for COS to B1/B2 Efile now since I have car to sell and other stuff?

You can apply for a COS from H-1B to B-2 using the I-539. You will want to do so before your the date on your last pay stub. You will want to include proof of your financial ability to take care of yourself and a separate letter explaining the reason you need to take care of things.

2. If I get a job before B1/B2 approval, how do I continue on H1 ?I assume my employer files for H1 extension.

Your new employer would need to file for a new H-1B extension for you. You can include evidence of your pending B-2 COS with that new H-1B filing. You may want to consider requesting premium processing so the new H-1B could be approved before the chance that your COS to B-2 could be denied.

3. If I get a job AFTER B1/B2 approval and also after expiry of H1 ( July 31), how do I get back onto H1?

If you have H-1B time remaining, you simply file COS paperwork on I-129 for new H-1B and COS from B-2 to H-1B. You should be fine for an H-1B extension as long as you have H-1B time remaining and your COS should work so long as you have B-2 time remaining.

4. If I go back to India,after expiry of my current H1, how can I revive this H1 with the current employer or New Employer?

You would have to file new H-1B paperwork and recieve a new H-1B approval. This H-1B paperwork should not be counted against the H-1B cap.

5. If I apply for 2010 quota, can I be counted against old H1? or do I get new H1?( meaning 6 years?)

If you are outside of the U.S. for one year, you can either file for remaining H-1B time (3 years?) or file for new H-1B under new H-1B cap.

question:what all documents I should send to support my application?

A.

In order to file for a COS from H-1B to B-2, you should include:

(1) Copy of your H-1B approval notice;

(2) Copy of your H-1B visa and I-94;

(3) Copy of the face page of your passport;

(4) Copy of 3-4 most recent pay stubs;

(5) Copy of recent bank statement(s);

(6) Letter explaining reasons why you need to stay in the U.S. as a visitor (i.e. apt./home, car, financial issues to resolve, commitments etc.)
