Re: Get username and password

That's a really broad question, more the sort of thing you'd ask on a paid site. I presume that yahoo wouldn't expose that information, I'd sure hope not. I can't think of why you'd want it, except to steal someone's account. And that would be bad.

CodeDom

I am finishing up work on a windows service that uses CodeDom to dynamically
compile code.

The problem I am running into is that the the compile fails with a
NativeCompilerReturnValue of 2000.

I assume this is probably a security issue, but I don't know where to start
looking for a resolution. Running the code as a WinForms app is not an
option.

Any suggestions would be greatly appreciated. Thanks!

How can i do this and for the same plz provied me the code.

This is two problems, both widely documented on the web. One is to get the data out of SQL Server. Then next is to iterate over this data and write it to a file. If you haev VB2005, you have the my.filesystem shortcut, which just hooks into the System.IO namespace to create files.

XML writing

BobsAfro14-Jan-07 22:45

14-Jan-07 22:45

I have written a web service that builds an XML document and returns it as a string.
But at the moment it builds the XML to a file (using System.Xml.XmlTextWriter) then
opens the file (using XmlDocument.load(c:\... etc)).

Is there a way to write XML directly to a string? As writing to a file can cause problems
with file access and so on if there is any errors.

how to read files fast?

Hi,

Just started to learn about reading files, text, binary, whatever. I thought, hey, I can make a Hex editor like this, beginning with a Hex reader offcourse. Got to start somewhere and I just want to learn.;P
Here's my code so far

  Dim bytArray As Byte()<br />
        Dim intFileLenght As Integer<br />
        Dim bldHexData As New StringBuilder<br />
        Dim bldCharData As New StringBuilder<br />
        Dim i As Integer<br />
<br />
        If dlgOpen.ShowDialog = DialogResult.OK Then<br />
            strFileName = dlgOpen.FileName<br />
<br />
        End If<br />
<br />
        Me.Text = strFileName<br />
<br />
        Dim strmFile As New FileStream(strFileName, FileMode.Open, FileAccess.Read, FileShare.Read)<br />
        Dim rdrFile As New BinaryReader(strmFile)<br />
<br />
        intFileLenght = strmFile.Length<br />
<br />
        bytArray = rdrFile.ReadBytes(intFileLenght)<br />
<br />
        For i = 0 To bytArray.Length - 1<br />
            Select Case True<br />
                Case bytArray(i) = 0<br />
                    bldHexData.Append("0" & bytArray(i).ToString("X") & " ")<br />
                    bldCharData.Append(".")<br />
                Case bytArray(i) < 16<br />
                    bldHexData.Append("0" & bytArray(i).ToString("X") & " ")<br />
                    bldCharData.Append(Chr(bytArray(i)))<br />
<br />
                Case bytArray(i) >= 16<br />
                    bldHexData.Append(Hex(bytArray(i)).ToString & " ")<br />
                    bldCharData.Append(Chr(bytArray(i)))<br />
<br />
            End Select<br />
<br />
        Next<br />
<br />
        txtHex.Text = bldHexData.ToString<br />
        txtChar.Text = bldCharData.ToString

This works on small files, but crashes on anything big (say, a divx movie of 700 MB), gives an OutOfMemoryException. Anyone know VirtualDub? It has a Hex editor, it opens a file instantly.

What magic is this? How do they do that? Is it at all possible in VB.Net?

It is an illusion. Like Penn and Teller.

SilentBob101 wrote:

Yes.

The secret to the illusion is that they only open a small part of the file at a time. They do not try to read the whole thing in to memory in one go. They also dump parts of the file that they no longer need from memory to free up space for the bit you are currently viewing.

Is that like this? Setting the buffersize at the end?
Dim strmFile As New FileStream(strFileName, FileMode.Open, FileAccess.Read, FileShare.Read, 2048)

Any chance you know how that's done? Or where can I find more info on the subject? It has to be VB.Net, I'm not yet ready for C# Wink | ;)

No, but I can work it out.

The high lever overview is:

I'd create a virtual file object that tracks where I actually am in the file. It would maintatin an internal buffer that contains the details of the area of the file you are currently interested in.

On the presentation layer part, I'd create a control that only contained the representation of what is currently on the screen. If the user scrolls the control it goes back to the virtual file to read the next bit (or previous bit).

If the user changes anything the virtual control would also maintain a change history that it would give out in place of parts of the real file. When the file was closed the change history would be used to write the changes to the disk quickly an efficiently.
