Hi
I set a view state as following:
ViewState["roomsql"] = SqlDataSource_rooms_to_update.SelectCommand.ToString();
I then use an if statement to check if its blank:
if ((string)ViewState["roomsql"] == "")
however the if statement doesn't work as it constantly reads the viewstate as having a value in it when it doesn't
has anyone encountered this problem before?
thanks

If (string)ViewState["roomsql"] contains a null value then your statement if ((string)ViewState["roomsql"] == "") will always return false.
Try checking for null rather than "".

You always pass failure on the way to success.

Use string.IsNullOrEmpty((string)ViewState["roomsql"])
And I really wouldn't recommend you storing SQL in the viewstate. It is too easily read and the SQL would likely contain information that a hacker would find useful.

I'd also advise against it because it's just plain bad practice coupling the view to the database like this.

Hi everybody!
I want to serialize a B+ tree. My class structure is the following:
class BPlusTree
{
private Node root;
private int nodeSize;
private class Node
{
private List<node> nodes;
private List<object> keys;
private bool isLeaf;
private List<object> values;
private Node parent;
private int size;
}
}
I don't know if it is possible to serialize a tree.All the example which i found serialize just simply classes. None of them didn't serialize a class which has an inner class.
Is it possible to make this tree serializable? If it possible how can i make this?
Thanks a lot for your help!
Have a nice day!

Mark both classes as Serializable, and implement a public property for each field. It can now be serialized.

No problem. Glad to help.

Hi,
I need to send email from C#.NET windows form i am able to send the mail successfully.
But there is a problem that i need small image in signature so how can i send image in email signature...........
|

The best way, is to assume it's HTML mail and include a link to the image somewhere on the web. If it's not HTML mail, you can't do it.

You will have to send the mail as HTML, you can also embed the image as a linked resource if required.
MailMessage mm = new MailMessage();<br />
<br />
<br />
AlternateView av = AlternateView.CreateAlternateViewFromString(body, Encoding.Unicode, "text/html");<br />
<br />
imageStream = new MemoryStream(resourceImageBytes, false);<br />
LinkedResource imageResource = new LinkedResource(imageStream);<br />
imageResource.ContentId = "signature";<br />
imageResource.ContentType = new ContentType("image/jpeg");<br />
<br />
av.LinkedResources.Add(imageResource);<br />
<br />
mm.AlternateViews.Add(av);

I have search Google but not found such type of designing tool for creating softwares. Just like VS.net diagram tool but with extra functionalities.
Please provide only name or link.

You want something that does more than VS.NET but is free ? More in what way ?

Like ProxyDesigner or MetaMill?
But the latter is shareware, I guess.

I have 3 textboxes on my webform (Sender's email,name, age).
When they hit submit, an email must be sent to an email address eg. me@gmail.com with the subject and the body should be the information from the 3 textboxes.
How can I do this?

1 - try using the ASP.NET forum for ASP.NET questions
2 - try using google first, the web abounds with examples on how to perform this trivial task

Have a look at
System.Net.Mail namespace.

Hi.
I want to convert a word typed in english to its corresponding word in tamil.
This has to be done in C#.net.
Pls suggest me how to do this.

Create a database by typing in an Enlgish to Tamil dictionary, and then make a database call.
Sorry, that's it, it's a programming language, there's no translation services built in.

Perhaps there is one free editor which I have also shared it here, which should help you out:

Hi.
The form controls are not refreshed sometimes when the form is opened.
Just try closing the form and opening it once again.
