Me.Xmpp1 = New nsoftware.IPWorksSSL.Xmpps(Me.components)

Try System.IO.File.Exists at the application's entry point before any use of the dll.

But Where can I write the Code.
because,It is Unable to build the application.
I am using a control of that dll and if the dll is missing it give me error at the design time
|
|

|

So the problem is not about checking the dll at the start of the application. Make sure you referenced the file and it is at it's location. Try re-referencing it again. Maybe if you provide more details i'll be able to help. Try browsing the assembly in the Object Browser and see if it works.

No actually not,
I am creating my application and debug with that dll and it is worked find.
but when I am using .exe file, at that time if that dll is missing then a message will display.
"The Application has encountered a problem and needs to close. We are sorry for the inconvenience "

Where is your .exe file? Does the dll exist in the same directory? If it doesn't, go to the Solution Explorer -> References and set the Copy Local property of the reference to true. See if this work?

use following code given below :
if system.io.fileExists(application.startuppath & "\" & "your dll file name") then
print a msg that it exists
else
print a msg that dll file not found.
Hope this will be useful for you.

If you want your application to be able to start without the dll (which you have to if you want to check if the file exist), you have to load it dynamically instead of having a reference to it. That also means that you can't use any early binding, you have to use reflection to do late binding for anything that you use from the dll.
Despite everything, the person most likely to be fooling you next is yourself.

Dear All,
I am trying to use form closing event for poping message for saving the data before closing the application with X at upper right corner.
But my code is not working. my application closes without poping message box.
Private Sub Form1_Closing(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs)
Dim a As Integer
a = MessageBox.Show("Are you sure to close", "Text", MessageBoxButtons.YesNo)
If a = 6 Then
'Application.Run()
e.Cancel = False
Else
' Application.Exit()
e.Cancel = True
End If
End Sub
Thanks in advance........

Hello Kisran,
I am not sure whats wrong at your side. But your code works perfectly at my end.
In case you are not able to resolve it, you can probably try this slight modified
version of your code.
BEGIN CODE
<br />
Dim dr As DialogResult = MessageBox.Show("Do you wish to close the Form", "Closing Form", MessageBoxButtons.YesNo)<br />
If dr = Windows.Forms.DialogResult.Yes Then<br />
e.Cancel = False<br />
Else<br />
e.Cancel = True<br />
End If<br />
END CODE
I hope this works.
Regards,
Allen

Try the following code :
Protected Overrides Sub OnClosing(ByVal e As System.ComponentModel.CancelEventArgs)
dim res
res=msgbox("Do you want to close?",msgboxstyle.yesno,"sample")
if res=vbno then
e.cancel=false
else
e.cancel=true
endif
MyBase.OnClosing(e)
Hope the above code will work...

Try again this one:
Protected Overrides Sub OnClosing(ByVal e As System.ComponentModel.CancelEventArgs)
dim res
res=msgbox("Do you want to close?",msgboxstyle.yesno,"sample")
if res=vbno then
e.cancel=false
else
e.cancel=true
endif
MyBase.OnClosing(e)
end sub
Put end sub after mybase.onclose(e) statement

Hello All,
How can I create a setup for updates using VS 2005?
This update setup should contain only new/modified files. And when this update setup file will run, it should automatically detect the installed path, and must be able to copy/overwrite the new files.
Thanks in advance...
Amit

Your question is pretty vauge for such a broad topic. There are all kinds of different settings that need to be tailored to your specific project. You should probably start by reading some articles[^] or doing some google searches[^]. You may want to specifically search for the keyword ClickOnce[^], which is an easy to use deployment for VS 2005 but has some limitations.
Hope this helps.

Hello,
First of all, you need to set the DataSource and DataMember for the BindingSource. Then you can
use set the desired bindingSource.ColumnName in the Text property under DataBindings() in the
Properties Windows(Located at the top on the window) of the TextBox.
In the MoveNext and MovePrevious buttons, you can simply define the following code:
BindingSource1.MovePrevious()
or
BindingSource1.MoveNext()
For more information, you can visit the given link:
http://www.codeproject.com/KB/grid/BindSourceBindingNavCS.aspx[^]
I hope this will help.

Allen
