Hey all,
The query goes like this...
While browsing the internet on the web browser component,any pop-ups are by default opened on the IE.Is there any way to supress this kind of event and let my own browser open the pop-up?
Thanks in advance....

It's not your own browser. If it was your code would be parsing the HTML and script and executing the script so yes you could do it. Since it's not "your own browser" then the answer is in the documentation for the browser you are using.

WOW. Ok that was to a reply from the guy below and he deleted it so it wound up going to you, maybe, if you got it. Anyway.

Not sure what you mean. If there is a way you will have to find it by reading the documentation for the browser control and all it's interfaces, that's all I said in my post.

How to access an object of an arraylist, from a hashtable?

Ravi Mahavrathayajula31-Mar-08 4:08

I have declared a Hashtable.
The "Value" field of the hashtable refers to an ArrayList.
The Array List contains a list of objects.

Now how can I refer to a particular object in the arraylist referring to its respective "key" from the hashtable?

To make it clear I'm embedding the code here.

<br />
ArrayList errorlist = new ArrayList();<br />
Hashtable errorstable = new Hashtable();<br />
<br />
error = new Errorcodes(tokens[3].ToString(), tokens[4].ToString());<br />
errorlist.Add(error);<br />
errorstable.Add(tokens[2].ToString(), errorlist);<br />
<br />
//.......<br />
<br />
foreach (DictionaryEntry de in errorstable)<br />
{<br />
      if (de.Key.ToString() == fetchcodes[4].ToString())<br />
      {<br />
           string evalue = //<objectvalue>; <br />
           //Should retrive the object from arraylist corresponding to the value in hashtable. <br />
           SW.WriteLine("\t\t\t" + "public const int ");<br />
           break;<br />
      }<br />
}<br />
</objectvalue>

Have you looked at the documentation for the Hashtable class? If you can't figure it out by reading the documentation then buy a beginners book or take a course at a university.

Ravi Mahavrathayajula,

What are you trying to do?, eg: whats the problem your trying to solve. Just because its looks a bit complicated for something as simple as storing a list of "Errorcodes".

Regards,
Gareth.

Thanks for looking into the problem Gareth.

ErrorCodes is a class as shown below.

<br />
class Errorcodes<br />
    {<br />
        public string Errorvalue;<br />
        public string Errorcomments;<br />
<br />
        public Errorcodes(string Errorvalue, string Errorcomments)<br />
        {<br />
            this.Errorvalue = Errorvalue;<br />
            this.Errorcomments = Errorcomments;<br />
        }<br />
    }<br />

Now I actually need to read 3 fields into a loop, but as hashtables cannot process more than 2, I've read one as key and stored the other 2 fields as objects of the class error codes in a hashtable. Now as I retrieve a "Key" from the hashtable, its respective "Value" field must also be retrieved. But since the Value field in this case is actually an object of ArrayList, I was confused how could I retrieve a particular object that I needed.

You have to cast it from object to ArrayList. NOTE: If you are using .NET 2.0 or higher you should use Generic Containers to avoid the casting.

Sounds like you should use Collection or List<>. What happen if the key duplicates?

The "key" is unique and doesn't duplicate in this case. Please correct me know if I misunderstood your question.

Do not. Since you are using source control (of course you are, right?) this kind of comment is not needed. What is 100000000x more useful in case of nontrivial fixes is detail explanation what you fixed and how, or perhaps bug ID to your bug tracking system if you are using any (and detailed info is there).

I would probably use a macro instead. Put it on a hotkey for convenience.
I wrote one to put a review comment for when I go through files and do a
preliminary review.

Sub ChangeLastReviewDate()
    DTE.ExecuteCommand("Edit.Find")
    DTE.Find.FindWhat = "Last Review:"
    DTE.Find.Target = vsFindTarget.vsFindTargetCurrentDocument
    DTE.Find.MatchCase = False
    DTE.Find.MatchWholeWord = False
    DTE.Find.Backwards = False
    DTE.Find.MatchInHiddenText = True
    DTE.Find.PatternSyntax = vsFindPatternSyntax.vsFindPatternSyntaxLiteral
    DTE.Find.Action = vsFindAction.vsFindActionReplace
    DTE.Find.Execute()
    DTE.Windows.Item(Constants.vsWindowKindFindReplace).Close()
    DTE.ActiveDocument.Selection.EndOfLine(True)
    DTE.ActiveDocument.Selection.Text = "Last Review:" & Now() & " [Done by: SRP]"
End Sub

I guess you'll have to add a handler for the check-box event of your interest and write the code to redraw your datagrid to display the columns of your interest there.

1.Create an IceCreamConeException class whose constructor receives a string that consists of an ice cream flavor and number of scoops.
2. Create an IceCreamCone class with two fields:
• IceCreamFlavor
• Scoops

3. The IceCreamCone constructor calls two data-entry methods:
• GetFlavor(), which throws an IceCreamConeException if the flavor isn’t one of the following: vanilla, chocolate, strawberry, peach, or banana.
• GetScoops(), which throws an IceCreamConeException when the scoop quantity exceeds 3.

4. Create a program that establishes several IceCreamCone objects and handles any throw IceCreamConeExceptions.
5. Save your program.
6. Now “build” your program

Not sure about the rest of it, but Ctrl+S will help with step 5 and Ctrl+B should get you past step 6.

Good luck with the others. Be sure to post back with the grade you get!
