VB .Net Help to print list of files

Sun, 09 Jun 2013 05:36:28 -0700

Hello,

I need a code in VB .Net which will be invoked when a button is clicked and will get the list of files and subfolders under a parent directory. The path of the parent directory is stacked into another variable called folderpath. The code for folderpath is, folderpath = Browse.SelectedPath. Here Browse is another button which invokes an open dialog box for selecting a folder. The folderpath variable holds the value of parent folder.
I am looking for a code which will give me the list of files and subfolders under this parent directory.
Can anyone please help?

Thanks,
Abhijnan

Re: How to compare two xmldocument to find out if there any difference

Found this relevant article after looking around for a while.

You are going to have to loop through the nodes yourself as there is no method built in.

Hi!

In calculator is possible to convert e.g. PB to B.
So large symbols displays:

HOW TO DISABLE SYMBOL "E" TO SHOW NUMBER AS IS?

Many many thanks for every help, reply or comments.

connect to an access database on a server

Wed, 08 May 2013 05:55:40 -0700

Hi all,

I'm having problems with connecting to my database. The computer i'm on is connected to a server called BPL. That server is connected to a mainserver.

My database is on a hidden testmap called "publicshare$"

my connection string would normaly be :

Dim dbconn As New 0leDbConnection("Provider=Microsoft.ACE.OLEDB.12.0 ;Data Source= \\mainserver\publicshare$\TestTomDatabase\woordens pelNederlands.accdb")

You don't need a password to connect to the database, but i need to implement an other user name (eg. admin ) and a password (eg. adminpas) to connect to the map.

How should i chance my connectionstring so that i can do this ?

Wed, 08 May 2013 02:19:03 -0700

I am a total Beginners and just trying to create a simple progamme.

I want the user to click a button which will open a web page within the forum.I used the following code

Private Sub RPRulesToolStripMenuItem_Click(sender As Object, e As EventArgs) Handles RPRulesToolStripMenuItem.Click
WebBrowser.Visible = True
WebBrowser.Navigate("http://ucwonline.freeforums.org/")
End Sub

However when I run the Programme,all I get is a black screen in the VB.Net Browser.No text,nothing.Other sites such as Google and youtube seems to work perfect but not this one (It works perfect in the normal Browser)..Anyone has some suggestions or workarounds? I want to display the text from the site or the whole page but within the form without using any external browser.

Thanks!!

This VB.NET UPC-A Barcode Generator Library may solve your problem. It also offers detailed steps for generating UPC-A barcode in VB.NET.I think it's very simple.

Thank you Livetechs,

I resolve the problem by myself.
The problem was a syntaxis error in mysql command.

I modified the sql commmand adding ` single quote in the command.
strSQL = "INSERT INTO `Libros`(`Title`,`Desc`) VALUES ('" & Title_text.Text & "', '" & Desc_text.Text & "')"

Thank you for you help.

Error in VB.net with MYSql

Fri, 05 Apr 2013 12:49:37 -0700

Hi all,

I do not have to much experience in VB.net. I am doing small application to practice.

In this case I am creating a VB application conneting to a MYSQL Database.

The problem I have is when I try to make a new register into the DDBB, I recieve a syntaxis error.

INSERT INTO Libros(Titulo,Desc) VALUES ('" & Titulo_text.Text & "', '" & Desc_text.Text & "')

However if I use the command into mysql server it works fine.

INSERT INTO Libros(Title,Desc) VALUES ()

Private Sub Save_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Save.Click
-----------------

If sConnection.State = ConnectionState.Closed Then
sConnection.ConnectionString = "SERVER = my server; USERID = joserodriguezan; PASSWORD = Aberystwyth; DATABASE = Bibloteca;"
sConnection.Open()
End If
Try
strSQL = "INSERT INTO Libros(Title,Desc) VALUES ('" & Title_text.Text & "', '" & Desc_text.Text & "')"
Dim da As New MySqlDataAdapter(strSQL, sConnection)
da.Fill(dset)
Catch ex As Exception
MessageBox.Show("Error")
End Try

Tittle_text.Text = ""
Desc_text.Text = ""
Class_combo.Text = ""
Date_text.Text = ""
Pres_text.Text = ""
Who_text.Text = ""
Title_text.Focus()
list()
End Sub
-----------------------

Any knows how to resolve this problem?
Thank you.
