The real question is, how do you *expect* 32765 to convert to a color ? If you mean it's an RGB value, you can use int.TryParse to get a number, and bit masking to extract the three values, which you can then turn into a color. So, 32765 && 0xFF, 32765 && 0xFF00, and 32765 && 0xFF0000 will get your three byte values.

You can use the Color.FromArgb method to convert a number to a color. It expects a 32 bit value where there are eight bits each for alpha, red, green and blue.
If the value represents a color without an alpha value, you use FromArgb twice to set the alpha value. Example:
Dim c As Integer = &HFFFF00 'yellow<br />
Dim myColor As Color = Color.FromArgb(255, Color.FromArgb(c))
If your value represents a color in a different way, it may be simpler to extract the color components and create a color from that:
Dim myColor As Color = Color.FromArgb(red, green, blue)

Hello,
I know that there are many projects that show how to implement checking the md5 hash of a file in vb6 however I was not able to find any for vb.net can any one point me to the right direction ?
Thanks

Md5 is built into the System.Cryptography namespace. Therefore, no-one is going to write sample code to do it, the framework does it already.

I want to bind data in a Select Statement in a stored procedure in SQL Server 2005 to a GridView
in Visual Basic 2005.
I set the DataSourceID of the GridView to the Stored Procedure and in runtime Bind the Data with
DataBind Method.
But it dose not work.
Please help me.

It sounds like you have some misconceptions about how all this works. Post the code you're using to get the data and bind the grid and we'll see if we can straighten it out. Is this an ASP.NET app or Windows Forms?
You don't bind to a stored procedure. You call a stored procedure to return the records you want. The records end up in either a DataTable or some other bindable source. You then bind the grid to that record set.

What code? This is HTML. There's nothing here that calls any kind of database.

Hi,
I am have to use Sybase database in my appliction.
Is there any way to use it without installing ODBC Driver on each machine, I mean like is there any way to directly connect to Sybase by imporing a reference dll or something.
Thank you!

Well, you could TRY to use the OleDb methods, but they're not going to support SyBase the best since they're kind of "generic". Other than that, you have no choice but to install the driver, or use a different database, like SQL Server or Access, that comes with the drivers already installed.

If now OleDb wht other choice do i have, since i am using a IVR system that only deployes Sybase as their database.
Thank You!

I'm trying to create an application where i can browse the Active Directory OU folder structure. I need to select an OU and need the OU name for a next action in the application.
Any help is welcome.

Already found some information like this below, but it doesn't show any results:
mports System
Imports System.DirectoryServices
Public Class Form1
Class DirLister
Shared Sub Main(ByVal args() As String)
Dim enTry As DirectoryEntry = New DirectoryEntry("LDAP://192.168.1.1")
Dim mySearcher As DirectorySearcher = New DirectorySearcher(enTry)
mySearcher.Filter = ("(objectClass=computer)")
Dim resEnt As SearchResult
For Each resEnt In mySearcher.FindAll()
Form1.Text = (resEnt.GetDirectoryEntry().Name.ToString())
Next
End Sub
End Class
|
|
|
|
|
Replace this line :
Dim enTry As DirectoryEntry = New DirectoryEntry("LDAP://servername/DC=DCNAME, DC=local")
hopes it helps,

That didn't work either, i also changed it after your suggestion into:
Imports System
Imports System.DirectoryServices
Public Class Form1
Class DirLister
Shared Sub Main(ByVal args() As String)
Dim enTry As DirectoryEntry = New DirectoryEntry("LDAP://mydomain.local/RootDSE")
Dim mySearcher As DirectorySearcher = New DirectorySearcher(enTry)
mySearcher.Filter = ("(objectClass=computer)")
Dim resEnt As SearchResult
For Each resEnt In mySearcher.FindAll()
Form1.Text = (resEnt.GetDirectoryEntry().Name.ToString())
Next
End Sub
End Class
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub
End Class
Do i forgot something? I just want to test this with display the results at my empty form and work from there with the results.

Can you tell me what is not working correctly. Is it that you are not getting the required results or that you are getting an error message.

Ummm... To be frank, you're copying and pasting code that you don't understand at all, and I'm not talking about the directory searching code. It's this
Form1.Text = blah, blah, blah
in int your Main. The search code may actually be working, but since you put all this in the Main method, before the form even shows on the screen, you'll never see the results. And, the Text property of the Form just changes the TitleBar text. It doesn't show up in the form itself.
Get rid of Main method and move it into the Form_Load event. Add a ListBox to the Form and expand it to cover the form. Then change the code in the Form_Load event:
Dim enTry As DirectoryEntry = New DirectoryEntry("LDAP://your AD server/AD path to search")
Dim mySearcher As DirectorySearcher = New DirectorySearcher(enTry)
mySearcher.Filter = "(objectClass=Computer)"
Dim resEnt As SearchResult
For Each resEnt In mySearcher.FindAll()
ListBox1.Items.Add(resEnt.GetDirectoryEntry().Name)
Next

Thank you, i got it working with your supplied code. Just need some finetuning now, but this is working.

I also got i working with a treeview and a OU list. I changed:
ComboBox1.Items.Add(resEnt.GetDirectoryEntry().Name)
into:
TreeView1.Nodes.Add(resEnt.GetDirectoryEntry().Name)
The problem now is that i only see a list of OU's and not into a real treeview.
So i see:
OU1
OU2
OU3
OU1a
OU1b
Instead of:
- OU1
- OU1a
- OU1b
etc.
How can i get this working?

Your searching the entire subtree under the starting container. Don't.
The trick is to populate only the top level of the treeview, putting a dummy child under each leaf so you get the little plus sign next to it. Upon the user clicking each node, you have to requery AD to get the containers under that particular node, and fill in the nodes under the node that was clicked.
Didn't think this was going to be that complicated, did you?
