Dear Dave!
Thanks for the help.
Now the source string looks like :
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\TECHNOPACK\technopack.mdb;User Id=Admin;password=;Jet OLEDB:Database Password=bill1234
and the destination string is like the following :
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\TECHNOPACK\tmptechnopack.mdb;Jet OLEDB:Engine Type=5;Jet OLEDB:Database Password=bill1234
The error was still on and after a little bit of searching i found that in my declaration of jro jetengine ,new keyword was missing, now the problem of compacting is over!!! Thanks!
For windows netwroking, can you give me any good location address from where I can get more about that.
I have also found that, if I try with permissions for "Everyone" (permissions to read,list,write and execute) my problem would be solved. Do you think it's a good idea?
furthermore, I dont see any user with this name or any group, but this word does work! can you explain a bit!
Regards
arunendra
N.B another thing! do you mind if I ask something else under this subject line. if yes then only i will ask.
thanks again for the help.

What do you think "Everyone" means? It doesn't care what the username is, authenticated or otherwise.

when i upload my webpages on server its giving error:
Server Error in '/' Application.
--------------------------------------------------------------------------------
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
<!-- Web.Config Configuration File
<configuration>
<system.web>
<customErrors mode="Off"/>
</system.web>
</configuration>-->
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.
<!-- Web.Config Configuration File
<configuration>
<system.web>
<customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
</system.web>
</configuration>-->
after changing the web.config file....
<customErrors mode="Off"/>
its giving the same error.
how can i make my login page as a indexpage.
its urgent plz

Turn customErrors to On so you will se what error you get and then you will be able to fix it.
And we don't care if it is urgent so don't bother writing that.

I think you might need to use installshield.

can you be abit more specific and can you give some more details, i think it will then be easy to understand your problem

Try to spend some of your time to research with this website[^]. I hope you could find what you need with this software.

Well, you could create a custom action for your installation project that ASKS first if the user wants to run the app after the install. Then, if so, just use the Process[^] class to launch it.

Huh?? Are you saying that the shortcut you put into the install just opens the location of the .EXE?? Modify the shortcut in your installation and add the name of the .EXE to the path.

I have made an instance of the BookSale Object after the mnuCalculate
but when I try to access any properties of mBookSale in a a new event sub procedure I get the message mBookSale is not declared.
Private Sub mnuCalcSale_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuCalcSale.Click<br />
<br />
Dim mBookSale As New BookSale<br />
mBookSale = New BookSale<br />
With mBookSale<br />
.Title = txtTitle.Text<br />
.Quantity = CInt(txtQuantity.Text)<br />
.Price = CDec(txtPrice.Text)<br />
End With<br />
lblExtendedPrice.Text = FormatNumber(mBookSale.ExtendedPrice)<br />
End Sub<br />
<br />
the above is all ok, below does not work! BookSale is a Class Module.
Private Sub mnuSummary_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuSummary.Click<br />
<br />
<br />
strMessage = "sales Total " & FormatNumber(mBookSale.SalesTotal)<br />
<br />
MessageBox.Show(strMessage, "Summary Totals", MessageBoxButtons.OK, MessageBoxIcon.Hand)<br />
<br />
End Sub
When I try to access mBookSale.SalesTotal I get mBookSale is not declared.
the Class module is listed below.
Public Class BookSale<br />
Private mstrTitle As String<br />
Private mintQuantity As Integer<br />
Private mdecPrice As Decimal<br />

End Property<br />

End Get<br />
End Property<br />

The reason you get this error is that mBookSale is indeed not declared in the mnuSummary_Click() event handler.
You have declared it in mnuCalcSale_Click() but it is only has local scope within that event - it is destroyed when mnuCalcSale_Click() exits.
If you want the mBookSale object to be available to all events, you'll need to declare it at a higher scope level (i.e. within the class that contains the event handlers).

Dear Steve,
Thanks for the reply.
I was coming to that conclusion.
I was getting confused with scope after an exercise where the objects were created in a frmLoad_ Event(local scope).
To populate a ListBox using Item.Add(NewObject(x,y,z) .
Then in a new procedure --> ListBox_Click Event <-- the object was addressed via its method ListBox.SelectedItem.GetPrice
This is still a bit murky for me....but I think I see that the ListBox contains the actual object so can be directly referenced.
Thanks Mick..

I won't paste the actual code, but I'll duplicate the circumstances
Class UI
Sub CallingSub()
dim strOne as String = Nothing
dim strTwo as String = Nothing
if txtOne.Text <> "" then
strOne = txtOne.Text
end if
if txtTwo.Text <> "" then
strTwo = txtTwo.Text
end if
dim objBusiness as Business
objBusiness.CallMe(strOne, strTwo)
End Sub
End Class
Class Business
Sub CallMe(ByVal strOne as String, ByVal strTwo as String)
....
End Sub
End Class
strOne in UI is Nothing when I pass it (this has been verified in debugging).
I put a watch on strOne in Business. As soon as Business.CallMe is called, strOne in Business.CallMe is equal to "-32768" as a string. If I pass strTwo as Nothing, it remains Nothing.
What is going on here?

Paste the actual code in use. Not the whoel thing, just the relevant parts. We've been burned too many times by "translated" code that works perfectly and is only slightly different from the actual code that's won't work.
But, I put together the exact same "circumstances" and the code works as expected. Both values come up as Nothing.
What version of VB are you using?

Hi
I am trying to convert a systemtime to a normal time. I am using the following code I found in a C# bit, converted it to vb.net
C#
private static DateTime SystemTimeToDateTime( ref SYSTEMTIME st )
{
FILETIME ft = new FILETIME();
NativeMethods.SystemTimeToFileTime( ref st, out ft );
DateTime dt = new DateTime( ( ( (long) ft.dwHighDateTime ) << 32 ) | (uint) ft.dwLowDateTime );
return dt;
}
VB.NET
Private Shared Function SystemTimeToDateTime(ByRef st As SYSTEMTIME) As DateTime
Dim ft As FILETIME = New FILETIME
NativeMethods.SystemTimeToFileTime(st, ft)
Dim dt As DateTime
dt = New DateTime(((CType(ft.dwHighDateTime, Long)) << 32) + CType(ft.dwLowDateTime, Integer))
Return dt
End Function
It all goes fine to the part CType(ft.dwLowDateTime, Integer) as in vb.net the filetime is returned as integer and not as int as it is done in C#. C# to VB converter converted the | into or. I found more articles use + so I changed it as well.
But as you can guess it doesn't work and I can't find any non C# stuff anywhere regarding this. So I gues s there is another way of doing or my code is just screwed. Can you help or suggest anything, except reprogramming everything in C# )
Cheers David

I haven't tested it, but it should be more like this:
Private Shared Function SystemTimeToDateTime(ByRef st As SYSTEMTIME) As DateTime
Dim ft As FILETIME = New FILETIME
NativeMethods.SystemTimeToFileTime(st, ft)
Dim dt As DateTime
dt = New DateTime(((CType(ft.dwHighDateTime, Long)) << 32) Or CType(ft.dwLowDateTime, UInt32))
Return dt
End Function
First, at the end of this equation, convert the value of ft.dwLowDateTime to a UNSIGNED Integer, not a signed integer. This can make all the difference in the world. On top of that, you can't add this value to the front of the equation. All kinds of addition carry overs will screw up the results. You must use a bit-wise OR, just like in the original C# code.
But, of course, the results will depend on the correct definition of the FILETIME and SYSTEMTIME structures. Hopefully, you didn't interchange signed integers for unsigned??
