I am getting problem in generating new GUID using its constructor who takes one string argument. like this
Guid regionID = new Guid(this.State.SelectedValue);
state gives 2 digit state code.The error says you need 32 digit with 4 dashes string to generate GUID.
any solutions ?

That's right, because GUID is basically 16 bytes separated in certain places by 4 dashes...
You can not have GUID with only two bytes.
If you want, you can do it like this:
byte[] guidBytes = new byte[16];<br />
<br />
Random rand = new Random();<br />
rand.NextBytes(quidBytes);<br />
<br />
guidBites[0] = Convert.ToByte(this.State.SelectedValue[0]);<br />
guidBites[1] = Convert.ToByte(this.State.SelectedValue[1]);<br />
<br />
Guid myGuid = new Guid(guidBytes);
this should works

This solution is really unlikely to help the OP because you have not taken into account what he might actually want a GUID for. You need to try to look at the bigger picture when answering questions because most are asking questions because they've got themselves in to a bit of confusion about something. Subsequently they may not ask the best question to get the answer they need.

I think you are confused about what a GUID actually is.
A Guid is a value that is generated by the system to be Globally (as in the world) unique. You should be able to generate as many guid values as you like on your machine and so could everyone else, but every value would always be unique.

You want to convert an access database into html? In what way? And why?
ASP.net runs off C# (or VB.net or whatever) - it's just a term to describe the web implementation of it.

I think you really need to define your requirements a bit better here.
Do you want to transfer data from your local server to the web server so that it then is stored in a DB on the webserver? Or is it that you just want static pages of html with teh data for display (and i would question why you would do that)?

my idea abt this is :
we r planning for 3 servers
1. main database server
2. web server for wide view
3. local database server (including replication server for parrel access)
few part of the information like reports, status of the product is needed to access on web server.So, whenever there will be a requirment of reports then how will data diplay to the user. As reports generation would be on
crystal report. how the format will change from .mdb into .html.
I really dont have any experience in online, so might be i may sound stupid

Well, I think crystal reports can access mdb database, and if not, then you have to convert .mdb file to a DATABASE format it can read. HTML is only generated by crystal report so there is no reason to convert mdb to HTML.
Briefly:
you include CrystalReportViewer control into your ASP.NET page and then you link it with particular report, stored on your disk or in repository. CrystalReportViewer will get the data from data source specified in report definition and will render this report as HTML (or another output format).
You understood, that you have data in mdb format and you want to have HTML output, but between these two states, there is lots of work!! Browse to google and search for ASP.NET / Crystal Reports tutorials, as I see you have no idea what Crystal report is about

I didn't say that it isn't possible in C#.
I said that it isn't possible. Period.
An HTML document is not a suitable format to handle the kind of data that you have in a database. You can of course display data from a database in a web page, but that is not a conversion, and from what I have seen I don't think that is what you are looking for.
If you want to send data over the web, choose a format that is better suited for it, like for instance XML.

I think the problem here is that you really don't understand web technologies. I would suggest some reading before tackling this.
We'll have difficulty helping you for such a general problem.

Hi friends.
I have a problem to send mail.
I got following error.
A socket operation was attempted to an unreachable host
SmtpClient smtp = new SmtpClient();<br />
smtp.Host = "68.16.152.154";<br />
smtp.Send(msg);
Pathan

|
|
Guess the smtp.Host should be "127.0.0.1" like the localhost
Hope this would help
Best Regards

I would be surprised if yes Unless Pathan has smtp server on his localhost. Obviously, ip address he specified is unreachable, it can be for several reasons. It can be misspelled, or can be behind proxy or firewall or something else.
