Hi !
Try this solution for your first proble. Just call the function you required, without brackets e.g.
se.logon_msg "ahmed","ahmed"
because as per my information, in VB the function call with '()' must hav it's LHS variable (LValue) to hold the valued returned by the call (though the function may not return anything). so, call the function without brackets...

You'll have to be a lot more specific than that. We're not teching classes on how to use the basic controls of VB6. What are you having a problem with?

Depending on how you've written your app,
Me.Text = "Processing..."
' Process pending messages, like repainting the window...
Application.DoEvents()
.
. ' Do you SQL processing...
.
Me.Text = "what it was before..."

I have used the Infragistic .NET Advantage suite in the past which has a control to output data in their Grid control to an Excel file. If you are using Excel 2003, you could just save the DataSet to an XML file, which Excel will happily read. Another way, write your data to a text file usign html tags for formatting and save the file as a .xls file. The advantage here is that you can incorporate forumla into your cells. For Example
<code>
<table>
<tr>
<td><b>Product</b></td>
<td><b>Price</b></td></code>
</tr>
<tr>
<td>Baked Beans</td>
<td>1.20</td>
</tr>
<tr>
<td>Musty Peas</td>
<td>0.79</td>
</tr>
<tr>
<td><b>Total</b></td>
<td><b>=SUM(B1:B2)</b></td>
</tr>
</table>

thanks alot for the help,
Can you kindly give an idea how to write to xml file, and if I am writing with HTML, do I have to write the details too as I am using in one computer ms office 2000 and other computer 2003. Sorry for my ignorance I really don't have any idea about it, if you can give me an idea I can learn more about it and will just use it accordingly.
Thanking you again

RegistryPermission
can someone describe me how this class wokrs for giving permission to registry paths? for example i gave Read Access Permission to HKEY_Currentuser\Myapp (MyApp is a personal key) . and then wrote a code like below:
my.computer.registry.setvalue(...
but still i have all access permission to this path.
i ran this code from same and different assembly but both can change the variables values in that path. what is the solution to set permissions for specific paths in registry during runnig an application?
|

I think you're misunderstanding what the RegistryPermission class does. It does not control access to the Registry key, but is a Permission that your code aquires so it can access the registry.
For example, about the best I can explain it is if your code was running from a network share, it wouldn't normally have Permission to Read/Write the registry. The use of this class by your code "asks" the CLR for permission to access the specified registry key. If Code Access Security is setup properly, your code can get the requested permission, if available to it.

Hello,
Almost all of my .NET coding has been ASP.NET so I haven't used a timer control much at all. Now I'm coding an application in which I have implemented a timer control that ticks every 1 second. It goes something like this:
Timer.tick fires
if it is the top of the hour,
do some stuff that takes 30 seconds or so
end if
My question is, what happens to the timer ticks while it does "some stuff for 30 seconds or so" ?

The Timer keeps running, piling up 30 seconds worth of Tick events!
In your Tick event handler, just disable the timer. Then at the end of the handler, re-enable it.
Private Sub Tiemr1_Tick(blah, blah) Handles Timer1.Tick
Timer1.Enabled = False
.
. do your processing here...
.
Timer1.Enabled = True
End Sub

Thanks Dave, it makes sense to disable the timer while I'm doing work. Here is what I've got:
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
If Now.TimeOfDay.Minutes = 0 Then
'Do work that takes 30 seconds
End If
End If
The work only happens twice since it takes 30 seconds. So the ticks sort of build up while I'm doing work and then flood on through after the work is done I suppose. Otherwise the work would run 60 times in the minute at the top of the hour, correct? Now.TimeOfDay.Minutes only gets evaluated later on (after work is done) it seems, and not when the tick actually occurs. That is what it seems like.
At any rate, I will my code change to:
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
If Now.TimeOfDay.Minutes = 0 Then
Timer1.Enabled = False
'Do work that takes 30 seconds
Timer1.Enabled = True
End If
End If

Hello!
It is an asp access based web site. The entries in the asp pages have entered in Turkish and there is no problem displaying the turkish characters in asp pages. However, when I record the entry in to access database file and then re-open the file, I have seen different ascII characters instead of Turkish characters. I have hosted the web site in the states. Can localization cause such problem by the server?
Is there a way to see exact turkish characters in the access database file.
Thank You

okay, I'm a baby programmer, so don't laugh if this question is too obvious, but I've been stuck on this for hours now
Very simple assignment - select data from an access data base
using a data adapter and use the fill method to populate a data set
I've looked at several examples that I've found on line and don't see what's wrong with my code. I always get a message on the adapter.fill line saying 'no value passed for one or more parameters'
I see examples that dont just say adapter.fill(datasetname)
and others that others that give a name for the name for the results within the data set, but I can't get either of these to work
heres the latest attempt
Thanks
Protected Const CANDIDATESRESULTS As String = "Results"
Protected connection As OleDbConnection = New OleDbConnection(connectionString)
Public Sub OneCandidate(ByVal CandID As String)
Dim candidateInfo As String = "SELECT * FROM CandidatesResults where CandidatesReulsts.CandidateID = '" & CandID & "'"
Dim candAdapter As OleDbDataAdapter = New OleDbDataAdapter(candidateInfo, connection)
candAdapter.SelectCommand = New OleDbCommand(candidateInfo, connection)
candAdapter.Fill(candData, CANDIDATESRESULTS)
DG.DataSource = candData
DG.DataBind()
Dim connectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=..\..\SampleDataBase.notadb"
Dim candData As DataSet = New DataSet

Your code is a little out of order... You are dim'ing your connection string and your dataset after you've already connected to the database and attempted to fill your dataset. Try this:
Dim connectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=..\..\SampleDataBase.notadb"
Dim candData As DataSet = New DataSet
Dim con As OleDbConnection = New OleDbConnection(connectionString)
Public Sub OneCandidate(ByVal CandID As String)
Dim candidateInfo As String = "SELECT * FROM CandidatesResults where CandidatesResults.CandidateID = '" & CandID & "'"
Dim candAdapter As OleDbDataAdapter = New OleDbDataAdapter(candidateInfo, con)
candAdapter.Fill(candData, CANDIDATESRESULTS)
DG.DataSource = candData
DG.DataBind()

I can get this code to 'work' meaning not blowing up by dim the datagrid
(Dim CandDG As DataGrid = New DataGrid) inside the class that contains this public sub
the problem is the assignment calls for me to pass the data from the class to a form that calls the class. I haven't been able to get that to work
|
|
|
|
|
To pass the dataset from the class to the form you will need to modify the parameters of your method. Instead of just passing the ID string, you will also need to pass the dataset. But you will have to pass it by reference instead of by value. (passing by value will never change the original variable on the form side, by reference will)
So it will look more like this:
Public Sub MyMethodName(ByVal myID as String, ByRef myDataSet as DataSet)
That should get you started.
