Silly Error Message
The Operation Completed Successfully Error Message
So I am just trying to finish up my new program Twitter Talk when I am running a test and I get the following error message.
Should we start hiring error message checkers?
Any ways if you get this Win32Exception was Unhandled “The Operation Completed Successfully” error message my workaround was to uncheck the check box in the project properties that says: “Enable Visual Studio hosting process”. In the menu: Project -> Project Properties… -> Debug -> Enable the Visual Studio hosting process.
Hope this helps someone this solution came from: http://www.codeproject.com/KB/cs/globalhook.aspx?msg=2427545#xx2427545xx
Overwriting an Excel file destination using SSIS
This was a problem I racked my brains over for a while when I first started using SSIS. I found a few possible including using a File System task to copy a “Template” Excel file over the existing on, or generating unique files by appending the date. I simply wanted to overwrite the existing data just like the Flat File Destination gives you that option.
My work around was as flows:
Create the Data flow the way you normally would, then go to the Control View Then add two Execute SQL Tasks before your data flow is called so it looks like this
Step 1: Add Execute SQL Task 1 to Control Flow
Set both Execute SQL Tasks to use the Excel file
Step 2: Set Connection Manager
Set your first Execute SQL Task’s SQL Command drop your table which is also known as the sheet name of your Excel file.
Step 3: Drop Table
Repeat step 3 on the second Execute SQL Command this time create your tables.
That’s it. Good luck.
C# .NET and LyricWiki to lookup lyrics
Music is everywhere with today’s high speed internet is most home it is no wonder that music is even moving to the World Wide Web. Many radio stations allow you to stream their stations over the internet. Many websites have been developed around music, like www.jango.com, www.pandora.com, and www.last.fm. I recently released my second version of Jango Desktop and one of the features I implemented was the ability to look up lyrics. Before I started I was thinking about all the ways I could parse the lyrics out of an existing lyric’s websites database. During my searching I stumbled upon http://lyricwiki.org/. Here is a small description of LyricWiki from the website:
LyricWiki is a free site which is a source where anyone can go to get reliable lyrics for any song, from any artist, without being hammered by invasive ads.
At this point you are probably thinking to yourself the same thing I did “Great, but where do I start?” So today I am writing a step by step tutorial on how to use Lyric wiki in your .NET program.
Creating a simple lyric demo program:
Step 1: Create the Form
Open visual studio and setup your form to look similar to mine.
Adding the web service:
Because LyricWiki offers a web service, you will want to add it to your program as a web reference. Right click on your solution and select add a web reference, or in .net 3.5 add a service reference -> then go to advance and add a web reference. The service’s URL is http://lyricwiki.org/server.php?wsdl you will want to add it like below if you press go you should see the available methods.
Adding a Web Reference
Writing the code:
Double click on your button on the form and let’s right some code to handle the lookup.
Add this to the top of your code:
using LyricsLookup.org.lyricwiki;
Then add this to the button clicked method:
private void LyricsButton_Click(object sender, EventArgs e)
{
LyricWiki wiki = new LyricWiki();
LyricsResult result;
string artist = artistTextBox.Text;
string song = SongTextBox.Text;
if(wiki.checkSongExists(artist,song))
{
result = wiki.getSong(artist, song);
Encoding iso8859 = Encoding.GetEncoding("ISO-8859-1");
LyricsRichTextBox.Text = Encoding.UTF8.GetString(iso8859.GetBytes(result.lyrics));
}else{
StatusLabel.Text = "Lyrics not found in database";
}
}
Then run and test.
