I recommend doing your own homework. It tends to make it easier for you to do future homework, if you've built the foundation that your teacher intended.
If you do need to ask for homework help, try to make if of the sort where you ask a specific question and post code, not of the sort where you describe your homework broadly and show no sign of having given it any thought yourself.

When I open the web page "http://finance.yahoo.com/q/os?s=qqqq&m=2007-04" and view the source in
Internet Explorer with Notepad, the text I am looking for looks like
class="yfnc_h" align="right"><b><span id="yfs_l10_qavdf.x">11.67<
but when I use
RichTextBox1.Text = Inet1.OpenURL("http://finance.yahoo.com/q/os?s=qqqq&m=2007-04")
it looks like
class="yfnc_h" align="right"><b>11.67<
in the RichTextBox.
What happened to the
<span id="yfs_l10_qavdf.x"
Thanks in advance

Coding for what? You haven't metioned what you want this code to do.

Hello,
VS 2005
Strange problem with my visual studio.
I have typed datasets in the designer. I have table adapters that i have dragged from the server explorer. I have used these for the last couple of month. I have added queries, stored procedures, added and deleted fields in the table adapters.
Now, I added an extra column to one of my tables in sql server 2005. I right clicked the relevant table adapter and clicked configure, and included the extra column.
I build the program, but the changes to the table adapter does not reflect in the code. When I do the following: tableAdapter.insert() the extra column has not been included.
I tried this with another table adapter in the dataset designer by adding a new field. The same problem.
I used rebuild, i have deleted the table adapter and added a new one. I have restarted VS, and also restarted the computer. I have also opened the project on another machine. I have deleted the table adapter from the form designer and added a new one from the components tab. And still the same problem.
When I preview the data, the extra column is there. But not when I use it in code.
Can anyone please tell if they know about this problem and is there a way to solve it.
Many thanks if you can.

Hi Steve,
I have experienced a somewhat similar problem with datasets in VS 2003. Although I am still not sure how or why it happened, I managed to solve the problem by creating a new dataset with a another name and changing all references to the old dataset to the new one. So in your case for example you could delete the existing tableAdapter or keep it (same difference), and create a new one with the name tableAdapter1. Then just roam through your code and add a 1 where necessary.
Hope it helps,
Johan
My advice is free, and you may get what you paid for.

I've been trying to get an application that can compile code at runtime, then save it as a .exe file.
So basically what I did was go on MSDN, 'steal' some code (yeah, I know I shouldn't...) that compiled VB and try to change it so it could also save it.
Public Class Form1<br />
<br />
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load<br />
CodeEmitter.RunCode("Microsoft.VisualBasic.MsgBox(" & """" & "Hello World" & """" & ")")<br />
<br />
End Sub<br />
End Class<br />
Class CodeEmitter<br />
<br />
Shared Sub RunCode(ByVal code As String)<br />
<br />
Dim cmplrParms As New CodeDom.Compiler.CompilerParameters<br />
<br />
cmplrParms.GenerateExecutable = True<br />
<br />
cmplrParms.OutputAssembly = "C:/VBCompile.exe"<br />
<br />
cmplrParms.TreatWarningsAsErrors = False<br />
<br />
cmplrParms.WarningLevel = 4<br />
<br />
cmplrParms.ReferencedAssemblies.AddRange(New String() {"System.dll", "Microsoft.VisualBasic.dll"})<br />
<br />
code = String.Format("Public NotInheritable Class EmittedClass{0}Public Shared Sub DoWork{0}{1}{0}End Sub{0}End Class", Environment.NewLine, code)<br />
Dim pvdr As New VBCodeProvider<br />
<br />
Dim rslts As CodeDom.Compiler.CompilerResults = pvdr.CompileAssemblyFromSource(cmplrParms, code)<br />
<br />
MsgBox("Path: " & rslts.PathToAssembly)<br />
<br />
Dim assmbly As Reflection.Assembly = rslts.CompiledAssembly<br />
<br />
Dim t As Type = assmbly.GetType("EmittedClass")<br />
<br />
t.InvokeMember("DoWork", Reflection.BindingFlags.InvokeMethod Or Reflection.BindingFlags.Public Or Reflection.BindingFlags.Static, _<br />
Nothing, Nothing, Nothing)<br />
<br />
End Sub<br />
<br />
End Class
The original code worked until I changed
cmplrParms.GenerateInMemory = True
to
cmplrParms.GenerateExecutable = True<br />
<br />
cmplrParms.OutputAssembly = "C:/VBCompile.exe"
Now I get an error FileNotFoundException at
Dim assmbly As Reflection.Assembly = rslts.CompiledAssembly because it turns out that nothing was ever compiled to C:\ in the first place! 
Thanks in advance for any help!

Myclass is a reserved word.
Private Sub fun()
Dim obj As New class1
obj.funct(Button1)
'Button1 is name of the button in the form.
End Sub
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
fun()
End Sub
End Class
Class class1
Public Sub funct(ByVal b As Button)
MessageBox.Show(b.Text)
End Sub
End Class

I don't know if VB's the best way to do that.
Try XNA

Christian already gave you the correct answer to your question here[^]. Asking the same question again will not change the answer.

Hi everybody.
I have a website where users can upload their pictures. I need to automatically add the name of my website to any uploaded picture. is that possible? and How?
Thanks in advance...

Create a MemoryStream from the uploaded data, so that you can load the image into a BitMap object. Create a Graphics object for the bitmap so that you can draw on it. Save the BitMap to a file.

ok, but can you give me how to write to an image? and how to save it again? this is my question
OmarMallat
|
|
|
|
|
Use the Graphics.FromImage method to create a Graphics object for the image. The Graphics object has method that you can use to draw anything you want on the image, like text, shapes and other images. Use the Save method on the image to save it when you are done drawing on it.

ok, but I'm new in web development. in windows application it's easy to do that, but in web development how to put an exe file on the server to perform this task?? and how to call this exe? and how the exe can save directly to the server? or there is another concept?
the view about this is not very clear...

You don't have to do this in a separate program at all. The entire framework is available from within ASP.NET.

sorry but I can't understand how..
let we have a simple example.
I need to make a copy of each uploaded file..
in windows application: filecopy source, destination
build, and double click to copy the file
in web what should I do?
please, do not say that I'm stupid... but I don't know...

It works exactly the same in a web application. Put the code in the page, deploy the application, browse to the page.
There is one difference, though. The working directory is not the folder of the web application, so you have to use complete file paths. The Server.MapPath method gives you the physical path of a virtual address.
