This is probably because the VPN software adds a level of security akin to a firewall that's blocking everything inbound to your machine.
And what does this have to do with VB.NET?

Yes I understand the security issue which is implemented with VPN.
Dave Kreskowiak wrote: And what does this have to do with VB.NET?
When we install any VB.net application with Client Server Architecture and it has to contact any machine where VPN is installed could result into an error. I thought may be there is any solution for this so that application could run smoothly. This could be any authentication code which could be added

Take a look at the DigiOz Post To Web Form DLL. It does exactly that (includes source code and a demo project). You can get it here:

Scroll about half way down the page and you will see it.

I have a small VB.Net 2005 project that started out with a form that a user would select different options and things would calculate based on the options. The options could be saved and retrieved to xml files and everything worked great. Then I got the bright idea to have multiple screens (all the same options). I built a custom tabpage and added my controls to them and got them to work as expected. On the tab page I set some properties and call a routing on my main form (using my.forms.main.MyRoutine) and that routine reads the properties just fine. Now the issue is if I run something from the form itself I can't figure out how to access anything on the tab pages. I want to be able to read things like text boxes and such. When I run a button on the tab page I can send the info back but since the tab pages are dynamically created and added to thhe tab control I can't seem to access them. How do I do this?
I.e. in simple terms I add a custom tabpage with 3 text boxes to a tab control on my main form. How can I access those text boxes from a command on the main form? How can I access text boxes on other tabs?

Salaam Alaikom
you can solve your problem by uisng RaiseEvent, this is an example to show you the solution
suppose you have a Form called frmMain, and you did class that add to integer numbers, you need to know if the fuction Add in the Class AddTwoNumbers called or not, so u need to add event for this case
Public Class AddTwoNumbers
Private m_firstValue As Integer
Private m_secondValue As Integer
Public Event OnAdd(message As String)
Public Sub New()
m_firstValue=0
m_secondValue=0
End Sub
Public Property FirstValue()As Integer
Get
Return m_firstValue
End Get
Set(value As Integer)
m_firstValue=value
End Set
End Property
Public Property SecondValue()As Integer
Get
Return m_secondValue
End Get
Set(value As Integer)
m_secondValue=value
End Set
End Property
Public Function Add()As Integer
RaiseEvent OnAdd("The Fuction Add is running now")
Return m_firstValue + m_secondValue
End Function
EndClass
now in your Form "frmMain" do this add 2 text boxes ["txtFirstValue","txtSecondValue"] boxes and a button "btnAdd"
Public Class frmMain
Private WithEvents m_addClass As New AddTwoNumbers()
' here you can handle the Event OnAdd in the class AddTwoNumbers,
'that means when you call the method m_addClass.Add() the following
'event will be fired
Private Sub addClass_OnAdd(value As String) Handles m_addClass.OnAdd
MessageBox.Show(value)
End Sub
Private Sub btnAdd_Click(sender As Object,e As EventArgs)Handles btnAdd.Click
' add the values of the input textboxes to the class
If IsNumeric(txtFirstValue) Then m_addClass.FirstValue=CInt(txtFirstValue.Text.Trim())
If IsNumeric(txtSecondValue) Then m_addClass.SecondValue=CInt(txtSecondValue.Text.Trim())
'call the function Add, you will see 2 message boxes, one fired
' by the event that is found in the class and you handled it in
'this form, and the other by the following message
MessageBox.Show(m_addClass.Add().ToString())
End Sub
End Class
finally, have you a nice programming time ![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)

Thanks for the reply but that confused me more. Heres what I have. I have a tab control on my main form. I dynamically add tab pages to this tab control. There are a couple text boxes on each dynamically created tab page and when I click a button on the main form I want to get the values of them back. But I can't seem to access the tab page or the text boxes because once its added I don't know how to reference it. Do I use something like the above and if so how do I keep track of multiple tab pages? Say I have 5 dynamically added tab pages, how can I access the text boxes on tab page number 3?

I gave up on the whole raise events stuff. For now I made a bunch of "holder" boxes on the main form and in the "Enter" event of the tab pages I assign the stuff on the tab page to the stuff on the main form holder boxes (like My.Forms.Main.CheckBox1 = Me.CheckBox1). Then the buttons on the main form just use the info in the holder boxes, which is always the currently displayed tab. This is working surprisingly good and when I do need to calculate something from all the tabs I just run through and select each one, grab the holder boxes for each, then go back to the one it was on. Happens so fast you can't tell what its doing. I'm sure this isn't the "proper" way but its working.....thanks for trying.

Hello all,
I need a little help on how to do something. I am working with VB.Net 2005 and I need to read through each row on a Data Grid and grab the values of each field and save it to a formatted String so I can pass that String over to a Crystal Report as a parameter. I can handle passing the String to CR but building it from the Data Grid is where I am getting stuck.
I need for it look like this….
Row1Value1(tab) Row1Value2(tab) Row1Value3
Row2Value1(tab) Row2Value2(tab) Row2Value3
I really appreciate any help/suggestions that anyone can provide.

I can see this getting ugly very fast...
All you have to do is iterate over the collection of rows in the DataGridView. And in each Row, iterate over the collection of cells:
For Each r As DataGridViewRow in DataGridView1.Rows
For Each c As DataGridViewCell in r
Dim value As String = c.Value.ToString()
Next
Next
You'll, of course, have to modify this for your own situation. It won't concatenate a string together. It just shows you have to get at the values.

Thanks Dave, I will see take this example and see what I can come up with over the weekend. As always, you are a great help!! Have a great weekend!

Hi,
To set a String with tabs, try the following code. Its a modified version of what Dave provided.
<br />
Dim mainStr as String = ""<br />
Dim rowStr as String = ""<br />
<br />
For Each r As DataGridViewRow in DataGridView1.Rows<br />
rowStr = ""<br />
For Each c As DataGridViewCell in r<br />
If (c.ColumnIndex > 0) Then<br />
rowStr += ControlChars.Tab<br />
End If<br />
rowStr += c.Value.ToString()<br />
Next<br />
mainStr += rowStr + ControlChars.CrLf<br />
Next<br />
This code will produce the results as u wanted i.e.
CCG3 wrote: Row1Value1(tab) Row1Value2(tab) Row1Value3
Row2Value1(tab) Row2Value2(tab) Row2Value3
Hope this helps to your expectations.
Thanks
Terry

Dim MsgDirPath As String = mats.GetSetting("UnpackLocation")
The above code will get a string (a path to a file like F:\folder1\aaaa.exe). Now if I need just the filename(i.e. "aaaa"), how do I get it? I can't use trim as the length might vary everytime I change the path. Probably there are more options for using Trim() that I don't know.
Any kind of help or suggestions are appreciated.
|

Checkout the Path class in the System.Io namespace. It exposes methods to manipulate path strings.
|
|
|
|
|
One option would be to split on "\", take the last string in that array and split it on "." and take the first string in that array.
|
|
|
|
|
Bad idea considering the path seperator character can be changed.
|
|
|
|
|
Thanks Dave. Problem resolved.
System.IO.Path.GetFileNameWithoutExtension(FullPath)

Yeah your method also works. But thats tideous. Anyway thank you for your time.
|
|
|
|

You can use “split” to split the string at desired character and then use mid to get the desired result
A sample code is written bellow.
You have to tweak the codes for exact requirements
Just create a Project on the form create a button named button1 and past the code in the form1 class
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim str_temp As String
Dim str_spliter As Object
str_temp = "F:\folder1\aaaa.exe"
str_spliter = Split(str_temp, "\")
MsgBox(Mid(str_spliter(2), 1, (Len(str_spliter(2)) - 4)))
End Sub
Good luck...

Hi I've got a datagrid bound and wish to print the details in black and white.
I've downloaded the datagridviewprintclass and the example code shows
dim frm as new frmPrint.
However, frmPrint is not a recognised type when I declare it.
Please help I've been trying to work this out for 3 days now

Your best source of information on that class is going to be whoever wrote it.
But, that line of code looks like it has nothign to do with that class. It's actually instantiating a new form, called frmPrint, which you haven't created in your project.

Hi Dave
Thanks alot for that. Have you any other ideas for printing contents of a datagrid. I understand it's quite complicated.
So far I've got the following code:
Private PrintFeeding As DataGridViewPrint
Private Sub btnPrint_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnPrint.Click
Dim fpr As New frmprint('COMING UP AS ERROR')
PrintFeeding = New DataGridViewPrint(PrintDocument1, dtgrdFeeding, True)
PrintDocument1.Print()
End Sub
Private Sub PrintDocument1_PrintPage(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage
e.HasMorePages = True
e.Cancel = True
End Sub
Private Sub btnPageSetup_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnPageSetup.Click
PageSetupDialog1.Document = PrintDocument1
PageSetupDialog1.ShowDialog()
End Sub
Private Sub btnPreview_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnPreview.Click
PrintFeeding = New DataGridViewPrint(PrintDocument1, dtgrdFeeding, True)
PrintPreviewDialog1.Document = PrintDocument1
PrintPreviewDialog1.ShowDialog()
End Sub
'(CODING IN EXAMPLE)'
'Private Sub btnPrint_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPrint.Click
' Dim fpr As New frmPrint()
' With fpr
' .Title = DataGridView1.CaptionText
' .ShowDialog()
' If .Result > 0 Then
' PrintGrid = New DataGridViewPrint(PrintDocument1, DataGridView1, .bBlackWhite)
' PrintGrid.PrintTitle = .bTitle
' PrintGrid.Title = .Title
' Select Case .Result
' Case 1 ' Print
' If PrintDialog1.ShowDialog() = DialogResult.OK Then PrintDocument1.Print()
' Case 2 ' Page Setup
' PageSetupDialog1.ShowDialog()
' Case 3 ' Preview
' PrintPreviewDialog1.Icon = fpr.Icon
' PrintPreviewDialog1.ShowDialog()
' End Select
' End If
' End With
'End Sub
Thanks

From the code you've posted, including the sample, it looks like you already having everything in place. That line of code that fails is instantiating a form that you don't have in your project. Since you rewrote the code, you don't even that line, so remove it.

I have a datagrid with textboxes below that are populated depending on whether a checkbox in column one is checked or not. My problem is that I want the first row to be selected as soon as the screen containing the grid is shown. Also, when switching to new row and changing check status results are not shown until I leave row and re-enter.
I am sure these are one in the same but not sure.

DataGridView1.Rows(0).Selected = True

That's because the value doesn't actually change until the cell commits the value from the control that it contains. The value in the control will not commit to the value at the cell level until the cell loses focus, either by going to another row, or by selecting the next cell in the row.
