so if you want to do this in c# why are you asking in vb.net forum?
what have you done so far, where are your problems? simply saying "I want" doesn't get you any answers, but the abuse of the community

Hi to everyone
I have added two COM components (Vlc player and windows media player) in my project. I wanted to know whether I should add some reference or do anything like that during building the set up and deployment project. Will those two component name be same in all machine?
thanks in advance

You should include them in your installer, as you cannot be sure that you PC on which the software is installed will always have them installed.

Hi Everyone,
I have a question about remoting. We have a server app running on a TCP port where clients can connect to do do all sorts of stuff. These clients are connected over the internet.
At the backend, we have our database which the clients query and some other applications ( including management app for the clients, a website etc) connects to this database.
Recently, we started moving everything into remoting hosted on IIS for easier use and scalibility ( since most of these apps are doing the same stuff in the same database)
Now my question is regarded to the Server application. In there, we have a list of clients ( list(of MyClientClass) to represent the collection of connected clients.
I would like to be able to query this "live" list of connected clients and do stuff with them from my different applications. Moreover, i would like to be able to put multiple of these Servers but still be able to treat the connected clients as one collection (if possible).
I was thinking remoting both the "client class" as the list of connected clients. Although this has a few minor performance drawbacks ( servers and IIS hosted remoting are in the same place connected over 1 Gbit Ethernet so that should not be such a worry right ?), it makes it easy to interact with the connected client collection.
Is this the way to go or should i consider other options ?
Thanks !

Hi to all,
could anyone please tell me how to restrict the user for different tabpage in a tabcontrol in vb.net2005
Basically in my code I want to restrict the user to click some particular tabpage in the tabcontrol. Like how we can do for button (button1.visible=false)...
The user should not be able to click only to view the contents
Or it will be more useful for me if there is anything like tabpage.visible=false. User wont be able to view the tabpage only
Thanks in advance

yaa! you are right. i just suggest to try whether it is works or not? I apologize for my previous post
however msgbox display "False" in following statement but visiblity status does not work accordingly
TabControl1.TabPages(3).Visible = False<br />
MsgBox(TabControl1.TabPages(3).Visible.ToString)

hello Rupesh...
you are right...So any other method we can do the same?

Tabcontrol is not meant for this purpose. All you can do is that either add and remove the tabpage whenever required. Other than this you can use WndProc method to trap when the user has clicked on the concerned tab page and filter it.

He never mentioned it is the last page. Instead of count - 1 thingy use the required index.

Hi everyone, I am facing two problems, kindly refer:
1) In Vb.Net 2005, how is it possible to make the
TabPage.Text to appear when the DrawMode of a TabControl
is set to OwnerDrawFixed. I have even tried to set the
TabPage.Text in the Form_Load event but of no avail. Plz help.
2) How can I draw a frame or groupbox or panel whose
style effect is 'Raised'. In most of the cases when we
set the Frame or Panel borderstyle to 3D, the style
effect is 'Sunken'. But I want it to be 'Raised'. This
is possible if you add the reference- Microsoft Forms
2.0 Object Library, choose Microsoft Forms 2.0 Frame
from 'Choose Toolbox Items' and set its SpecialEffect
property to Raised. But that is a COM component and I
want it to be done through core .Net framework
components. How is it possible.

Unfortunately you are unlikely to get that. That is effectively a more eloquent 'send codez plz!11'.
Now, the problem is that you have not said whether you want to remove the items from the DataGrid, or clear the object which the DataGrid is bound to. This will also clear it (I've not used it for a while, so you may want to check that). However, clearing the object which the DataGrid is bound to, does just that - clear it; when this has occurred, you must reload the object from another memory location or a file. Clearing the DataGrid itself doesn't touch the object. Which of the two to do you want to do?

not the object...
I just want to clear the datagrid on a button click...the scope of the object is not even there in the button....Its just a button iwth a caption "clear datagrid". Doesnot concern with any object
Thanks

In which case, you simply need to set the DataSource to Nothing; alternatively you could simply use DataGrid.Clear(). By the term 'object' I mean the database or data source which the DataGrid is bound to. Sorry if I caused any confusion. Incidentally, you could have found your answer from
|

|
|

In order to Clear a DataGrid control having a DataSource property set to some Object, you only need to write DataGrid1.DataSource = Nothing
this will clear the grid automatically.
Tell me whether this solution works or not.

I write some code as follow:
Module mdlTimerEvent_Drive
Private Declare Function timeSetEvent Lib "winmm.dll" (ByVal interval_Ms As Integer, ByVal resolution_Ms As Integer, _
ByVal lpFunction As [Delegate], ByVal dwUser As Integer, ByVal uFlags As Integer) As Integer
Private Declare Function timeKillEvent Lib "winmm.dll" (ByVal uID As Long) As Long
Private Delegate Sub timeCallback(ByVal uID As Integer, ByVal uMsg As Integer, ByVal dwUser As Integer, _
ByVal dw1 As Integer, ByVal dw2 As Integer)
Private Const elapse_Periodically As Integer = 1
Public m_nInterruptTime As Long
Private Sub TimeProc(ByVal uID As Integer, ByVal uMsg As Integer, ByVal dwUser As Integer, _
ByVal dw1 As Integer, ByVal dw2 As Integer)
m_lngNewCount = m_lngNewCount + 1
End Sub
Public Sub StartTimer()
Dim tmrProc As timeCallback = AddressOf TimeProc
m_lngNewCount = 0
m_lngTimerID = timeSetEvent(m_nInterruptTime, 1, tmrProc, vbNullString, elapse_Periodically)
End Sub
Public Sub StopTimer()
If m_lngTimerID > 0 Then
lngResult = timeKillEvent(m_lngTimerID)
End If
End Sub
End Module
I call mdlTimerEvent_Drive.StartTimer() and it run, but Vs.net show MDA exception "callbackOnCollectedDelegate" after seconds.
What shall I do?

Why do you need to use this instead of the built in timers ?
