There may be an MS SDK to do this, but you'd have to look for it, and it won't work all that well.

Hi,
I am a newbie to vb.net.
I am trying to build a program that crawls through google and gets me the top 100 links (first 2 pages of the search results) for a few searches. I have put all the keywords in a file.
I am able to retrieve the keywords in to my vb form.
I could also navigate through google for a relative search word.
but the loop doesn't work.
start loop with "keyword"
Step 1: navigate 2 google using the "keyword"
step 2: after the document loads, retrieve the first 50 links
step 3: click the "next page" link
step 4: after the document loads, retrieve the next 50 links
end loop
this works if I have only 1 keyword but if I have multiple "keywords" that need to be searched one after the other, I can get the links for the last keyword only.
How can I make the loop wait till all the operations of the previous loop in the webbrowser are complete.
Sorry for my bad english, as I am not an american.
Please help me.
Thanks in Advance,
Marshall

LOL - Americans all have bad English.

The web browser fires an event when the URL changes, amongst others. You should handle your processing there, so you can respond to each page as it loads, and then load the next one.

I have done. Sounds like now you need to. Is 'Multimedia and Graphics' the name of the class that assigned this homework ? If you're not willing to try it yourself, I recommend quitting now, and making room in the education system for someone who stands a chance of success.

Start .NET Framework Configuration Management Console (Start -> Settings -> Control Panel -> Administrative Tools -> Microsoft .NET Framework Configuration).
Then select "Assembly Cache" and click "Add an Assembly to the Assembly Cache" to add all DLLs into GAC.

U must have a stongname(name,version and public key).for that what i want to do? how can i add my component to gac

You need to make sure your dll is strongly named, just like the error message said.

Hi,
I had drawn some shapes in panel within in form. I want to make those shapes in panel as .jpg image and save it c:/.
Is there any way to make the drawing shapes in panel as image.
Thanks in advance.
Be simple and Be sample.

Draw them onto a bitmap instead of onto the panel. Show the bitmap in your program to view it, and call the Save method to save it.

What have you tried ? A blob field is usually used, but it depends on the database.

Hello all,
I am trying to create a simple VB application that will overwrite the FAT on a floppy with a set string I select. I found CFloppyDisk 2.0 (which is written in C++), And I cannot figure out how to complile it as a DLL that visual basic will allow me to reference. I realise this is a basic issue, but since the code was existing on this site I was hoping someone might know how to do it.

If the code was on this site, then it was in an article. Which means, teh forum of the article is the only place you'd especially hope to find help. The articles are submitted by all sorts of people.
If you compile a C++ dll, you can call it from VB using p/invoke. How are you trying to call it, now ?

I am trying to get a random letters from a set of Ascii codes, whereby i am only selecting certain keys (for example, the top row of the keyboard).
I am using this code:
Dim rnd As New Random()
---
Private Sub FORM1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim c1 As Char = Convert.ToChar(rnd.Next(97, 123)) : lblLetter1.Text = c1.ToString()
---
However, i cannot add more than the min max values in the next column, is there a way to do this, i.e. 97, 101, 105, 106...etc.
Cheers

Create a string containing the keys you want to choose from.
Dim keysToUse as String = "QWERTYUIOP"
Private Sub FORM1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim c1 as Char = ' '
while (Not keysToUse.Contains(c1))
c1 = Convert.ToChar(rnd.Next(97, 123))
This should keep looping until it selects a character that is in your string. Remember it will be case sensitive.

Put the characters that you want in a string, and pick one character from the string.
Dim chars As String = "qwertyuiop"
Dim rnd As Random = new Random()
Dim index As Integer = rnd.Next(chars.Length)
Dim c1 As Char = chars.Chars(index)

Oh, that works too.

im confused, sorry, bit new to all this. I have the following, how would i do it on this???
-----
Private Sub frmTestTop_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
RandomizeLBL(Me, "lblLetter*")
End Sub
Private Sub RandomizeLBL(ByVal container As Control, ByVal pattern As String)
Dim rnd As New Random
For Each ctrl As Control In container.Controls
Dim lblLetter As Label = TryCast(ctrl, Label)
If lblLetter IsNot Nothing AndAlso lblLetter.Name Like pattern Then
lblLetter.Text = Chr(rnd.Next(97, 122).ToString)
