Login failed – Error Number: 18456 – Severity: 14 – State: 1

Vish — Thu, 20 Aug 2009 10:54:00 +0000

I came across this error when I tried to Install MS SQL 2005 on Vista.I have installed SQL plenty of times and never had problems before on my XP.

My Problem :

The SQL 2005 did install correctly on my 64bit Vista but I was not able to log on to the server and it gave the following error

Error Number: 18456 – Severity: 14 – State: 1

Solved :

Instead of running SQL Server Management studio as current user I run it as an Administrator.
[ad#Link_5]
Then in the Object Browser Select the server > Security > Logins > New Login

Following window will be displayed

Click Search and the following window will be displayed

In the text box enter your username and press check name and press ok.

And you are done.

Now you will not have to run your SQL Server Management studio as an Administrator.

Thank you

Read a Web Page and send it as an HTML Email

Vish — Thu, 23 Apr 2009 01:43:46 +0000

Recently I was asked to write a code to send entire Aspx page as an HTML mail using VB.Net.
Private Function ReadAspxPage(ByVal url As String) As String Dim htmlPage As String Dim objResponse As System.Net.WebResponse Dim objRequest As System.Net.WebRequest = System.Net.HttpWebRequest.Create(url) objResponse = objRequest.GetResponse() Dim readpage As New System.IO.StreamReader(objResponse.GetResponseStream())


htmlPage = readpage.ReadToEnd()

readpage.Close()

Return htmlPage.toString() End Function

How to read HTML file onServer in ASP.Net

Vish — Thu, 23 Apr 2009 01:31:57 +0000

Private Function GetEmailTemplate(ByVal templateName As String) As String Dim sr As IO.StreamReader = New IO.StreamReader(System.Web.HttpContext.Current.Server.MapPath(templateName)) Dim body As String = sr.ReadToEnd() sr.Close() sr.Dispose() Return body End Function

Read all Mail Merge Field in an Collection.

Vish — Thu, 23 Apr 2009 00:37:49 +0000

I was asked to read all Mail merge Files in an HTML Template and then perform a mail Merge.
The MailMerge Fields were like ##[Field]##.
So thought to use regex to find the fields.

The biggest task for me was to write a regex for Matching ##[Merge Fields]##.

This is the code that I ended with.

Private Function GetEmailMergeFields(ByVal body As String) As ListItemCollection Dim list As ListItemCollection = New ListItemCollection


Dim pattern As String = "##\[.*?\]##"

Dim mymatches As System.Text.RegularExpressions.MatchCollection

Dim myregex As New System.Text.RegularExpressions.Regex(pattern)
mymatches = myregex.Matches(body)

For Each succ As System.Text.RegularExpressions.Match In mymatches

list.Add(succ.Value)

Next
Return list

End Function

How to set up Visual Studio Project to use NUnit-Gui Test Runner

Vish — Tue, 16 Dec 2008 22:57:18 +0000

I am writing this post to help people like me who are new to nunit. Bascially it’s easy to setup but some time it can be really hard for some people.

Here is how you accomplish the task :

Once you have created the test project, Right click on the project name in the Solution Explorer and select “Set as Default” from the options.
Now Right Click on the project again and select the “Properties”. The window as shown below will be displayed. Select the “DEBUG Tab”, In the “Statr Acton” select Start External Radio button and browse to select nUnit Gui Runner (the .exe file).

Once you have followed the steps above you are ready to run your test. Just run your solution and the nUnit Gui Runner will apear.

When you start application for the first time, NUnit opens with no tests loaded.

Select “Open” from the file menu and select the test. Now click on the run button and you are done.

Hope that helps,

Thank you

Now, you can run your test suite. By clicking the run icon in the Visual Studio toolbar the nUnit Gui Runner will popup but no tests will run automatically – however the Gui Runner will be populated with all the tests in your project. Now you just need to pick the test(s) you want to run and run them. If those tests (or the code they call) have any break points the Visual Studio window will reactivate when the breakpoint is reached and you can step through your code.

I hope this helps others embrace unit tests with .Net and Visual Studio

How to Use Code Behind to display text on Binding

Vish — Mon, 01 Dec 2008 08:46:38 +0000

I had to display Yes or No based on databind this is how I did it.

’
runat=”server” />

Also Bind will not work if you are databinding it.

Here is another example where I used code behind.

in Aspx :

OnSelectedIndexChanged=”EnableCluster” AutoPostBack=”true” SelectedValue=’<%# GetCheckBoxValue(Eval(“GLRSearch”)) %>’>
Yes
No
N/A

in code behind :

Protected Function GetCheckBoxValue(ByVal bool) As String

If bool Is Nothing Then
Return “N/A”
ElseIf bool = True Then
Return “Yes”
ElseIf bool = False Then
Return “No”
End If
Return True
End Function

Ajax CalanderExtender :Display dates of current (selected) month only

Vish — Thu, 27 Nov 2008 03:27:59 +0000

Today I have decided that I will start writting one post everyday. Lets see how far I go.

Today only one bug( rather a minor change) was requested by our clients doing UAT.

Problem : We have ajax calanderextender and it shows all the dates for the selected month.

Solution : So rather than doing something in the code the best thing to do was just try and chage the CSS.

And it did work like charm.
I added following lines to the CSS.
.MyCalendar .ajax__calendar_other .ajax__calendar_day,

.MyCalendar .ajax__calendar_other .ajax__calendar_year { color: White; }

And the problem was fixed without messing the CalanderExtender.

Thank you.
