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

AFAIK there is no visible property of tabpages.

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 ?

Hello to everyone,
I am facing the following problem with Vb.Net2005 project for different resolution monitor.
Initially I was doing my VB.net project using a 17 inch monitor. Now when I shifted my project to a flat LCD monitor with different resolution, my ALL CONTROLS POSITION ARE NOT LIKE BEFORE......In future I may have to shift my project to different monitor again. Moreover for deploying the project also, I don't know the resolution of clients monitor in advance....
Could anyone please give me solution for this.
Thanks in advance

Best bet is to buy a good VB.NET book. Read it. Look up 'dock' and 'anchor' in the index for how to lay out your controls so they resize for the form.

HI Christian,
Thanks for your reply...
I have at least 500 controls all over the project. Is there any way to do the same together or something like that..
Thanks

No, of course not. What magical way would there be to do that, unless you just want them all to sit on the top left of the form. Buy that book, and next time, set these things as you work on the project.

Set the Anchor property for each control according to your design
Your controls will be placed according to the resolution
