Hi,
My experience with the garbage collector is limited to seeing the guy empty the trash can outside my house.
What does the garbage collector do other/more/less than the dispose method?

.ShowDialog() returns a DialogResult that the form sets before it closes. Look up the docs on .ShowDialog() and it'll show you an example.

Dispose cleans up resources. The GC clears the memory. But, it does this in a highly optimised way, automatically. Callnig it yourself is pretty close to always just going to slow things down

Apostrophes inside a string in SQL has to be encoded, and depending on what database you are using, backslashes also. There is nothing special about quotes in a string, so if you have problem with them, there is something else that you are doing wrong.
For MySQL: Replace "\" with "\\" and replace "'" with "\'" (in that order).
For MSSQL, Access: Replace "'" with "''".

It can be done through Group Policy, not through your code. Unless you're building a kiosk machine, there's really no reason to do this.
Get your hands on the Windows XP or Windows Server 2003 Resource Kit (from Amazon) and either of those nice thick books will explain what Group Policies are and how they work in different networking or non-networked environments.

How do i convert Excel database file to Sql server database file dynamically?

If you mean getting the data from an Excel spreadsheet into SQL Server, where the spreadsheet is in a known format, I would read the data from your spreadsheet a line at a time and check for errors, then insert using an SQL Statement.
If this isn't what you were getting at, feel free to provide more information.

Excel is not a database, not even remotely.
You can control Excel using C# code, if you get the Microsoft libraries to do this, and you have Excel installed. Then you can read spreadsheet values and write SQL to put them into any database or other format you like.

It Depends on what you are actually trying to do.
Does the RTF document contain ready HTML code, and you only need to convert it, or do you just want to insert text from the RTF document into an HTML document?
If it contains ready HTML code you could just try
file.Move("yourHTMLfile.rtf", "yourHTMLfile.html")
Otherwise you'll have to read through both documents, combine the text from the RTF document with the code from the HTML document, and then create a new HTML document from the combined data.
Good luck,
Johan

Hi,
I am just not exactly sure what it is that you are trying to do, so I am guessing that you want to insert the text from your rtf file into a web page consisting of html code. Something along the lines of:
Text in the RTF file:
The quick Brown Fox Jumped Over The Lazy Dog
Content of the (empty) HTML file:
<br />
<html><br />
<head><br />
< title>blablabla< /title><br />
</head><br />
<body><br />
<br />
</body><br />
</html><br />
The text would need to be inserted between the body tags.
Is this what you are trying to accomplish?

Let me clear every point to you,
I have a RTF file at (bla bla ) location
and i just want to convert that file in to html file.
if i am directly save the file as HTML then all the content are display in binary format,
so how can i convert the .RTF file in to .HTML file
Clear ???
I am using vb.net 2.0

One thing you could try is to read the contents of the rtf file with a streamreader and then use a streamwriter to write the data into a new html file.
Something like this:
<br />
Dim sr As StreamReader = New StreamReader("Your_RTF_file.rtf")<br />
Dim sw As StreamWriter = New StreamWriter("Your_HTML_file.html")<br />
Dim line As String<br />
Dim content As String<br />
'read data from file<br />
Do<br />
line = sr.ReadLine()<br />
If line Is Nothing Then Exit Do<br />
content += line<br />
Loop Until line Is Nothing<br />
'write data to file<br />
sw.WriteLine(content)<br />
sw.Close()<br />
Otherwise my experience with file conversion is limited, sorry.
Good luck,
Johan

for text to speech i was thinking to create a audio files for each of the following numbers.
0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,30,40,50,60,70,80,90
Now My Question is
1. Am I think right to create the audio files for each of the above numbers ?
2. Which audio extention file(.wav , mp3 .. etc ) will be useful .I meant which takes less space.
