What do you mean when you are saying that it highlights the line? What is happening? What is the problem?

Hi Campbells,
I think u r right.
Access has a limited data holding capacity than SQL of not more than 10,000 records per table.
Thanx & Regards.

Hi Vikrant
I'm not sure about the limitation you mentioned about access since I already have an access database having a table of more than 11,500 records...

I killed the process which apparantly corrupted the uninstallation coz now none of the setup's function works.
Cant add/remove components, can't repair vs, can't uninstall.
Oh and my IIS is very unstable, again.
Who's joining me? I'm going to Bill Gate's house tonight to throw out all his windows!!
Thank for the tip, at least I can install VS 2005 then!

For future reference, there is a forum here dedicted to VS issues. This forum is more VB/VB.NET coding issues.

Really?? Too bad Bill can't control whatever else you have installed on the machine that might have messed with the huge number of components that VS installs and other stuff that it depends on...

My machine is out of the box, only components i installed so far was SQL2000, Norton Internet Security 2004, Windows Defender and Thunderbird.
Oh, and VS 2003, which I want off now, 3 days after installing it.
What I need is something that can fix the corrupted installation package, so that I can use my repair function.
Really can't think what could've messed up my installation, don't think Bill has an excuse.
Im running both 2003 & 2005 so I'll be rid of 2003 in a year or so when I format or upgrade again.

Make a textobx in which you will enter the information?
Make a configuration file in which you will store the information?

... and I think in VB 2005.
Why does it not expand all collapsed regions when you select Toggle All Outlining. This works in C#.

Hello. I was successfully able to convert VB6 to VB.Net, however I get an error when calling a declare function. Part of the code looks like this:
<br />
Declare Function iRasEnumDevices Lib "rasapi32.dll" Alias "RasEnumDevicesA" (ByRef lpRasDevInfo As Integer, ByRef lpcb As Integer, ByRef lpcDevices As Integer) As Integer<br />
Declare Sub iCopyMemory Lib "kernel32" Alias "RtlMoveMemory" (ByRef hpvDest As Integer, ByRef hpvSource As RASDEVINFO, ByVal cbCopy As Integer)<br />
Declare Sub iCopyMemory Lib "kernel32" Alias "RtlMoveMemory" (ByRef hpvSource As RASDEVINFO, ByRef hpvDest As Integer, ByVal cbCopy As Integer)<br />
<br />
Public Structure RASIPADDR<br />
Dim a As Byte<br />
Dim b As Byte<br />
Dim c As Byte<br />
Dim d As Byte<br />
End Structure<br />
<br />
Dim lpRasDevInfo As New RASDEVINFO<br />
Dim lpcb As Integer = 0<br />
Dim cDevices As Integer<br />
Dim t_Buff As Integer<br />
Dim nRet As Integer<br />
Dim t_ptr As Integer<br />
Dim i As Integer<br />
<br />
lpcb = 0<br />
lpRasDevInfo.Initialize()<br />
lpRasDevInfo.dwSize = Len(lpRasDevInfo) + (Len(lpRasDevInfo) Mod 4)<br />
<br />
nRet = iRasEnumDevices(0, lpcb, cDevices)<br />
<br />
t_Buff = GlobalAlloc(GPTR, lpcb)<br />
<br />
iCopyMemory(t_Buff, lpRasDevInfo, Len(lpRasDevInfo))<br />
<br />
nRet = iRasEnumDevices(t_Buff, lpcb, lpcb)
I get an error on the line nRet = iRasEnumDevices(t_Buff, lpcb, lpcb) that says:
"Object reference not set to an instance of an object". I ran the debugger and the only thing that gets set to Nothing is the parameter I pass in ByRef. I'm not really sure what is going on, but does anyone have an idea?
Mike - I love to program!

Mike,
I don't see your RASDEVINFO Stucture it should, at a minimum, look like this:
Public Structure RASDEVINFO
Dim dwSize As Long
<VBFixedArray(RAS_MaxDeviceType)> _
Dim szDeviceType() As Byte
<VBFixedArray(RAS_MaxDeviceName)> _
Dim szDeviceName() As Byte
End Structure
If you still have a problem with it, convert the stucture to a class structure, as you cannot pass a null value in VB.Net in a structure.
Also you need to do a lot more marshaling of most of that code.
There is an aritcle here on that, that may help you.

If you need anymore help feel free to email me and I'll see if I can help you work it out.

Dear All,
I am interested to know more about port knocking, and if it is possible through VB 6, please give me a sample code and description.

Hello 2 all!
How can i move any control, for instance a Button control on the VB Form's surface. Suppose when the form loads, its location is (0,0) and then after that i want to move this button with the mouse drage event and its position must be changed when i relese the mouse button, then what should i do?
If there is anyother option for that, you can tell me also...
Thanx in advance for helping me out
Regards,
Arfan Qadir

You might want to re-read the original post. He's looking for a runtime moveable control, not drag and drop support for data.

There's no option to make a control movable at runtime. You actually have to make your own version of the button and add support to move the control around while the mouse button is held down. There's actually quite a bit of code that goes into this. Too much to post into a forum message.
Basically, you create a new class, inheriting from Button. Add a couple of private fields to track where in the button the mouse is being held down (a Point instance works), and whether the control is being moved (Boolean).
Once that's done, the rest kind of falls into place if you think about it. Handle the button's MouseDown event to set the Moving flag to True and get the coordinates of the mouse point inside the button and save them in your private field. In the buttons MouseUp event, just set the Moving flag to False.
The MouseMove event is logically simple, but a little complicated in code. You need to calculate the new position of the control using the mouse position with respect to the buttons parent container, not the button itself. Then it's just a matter of a little math...
Public Class MovableButton
Inherits Button
Private _CursorOffset As Point
Private _Moving As Boolean
.
.
.
Private Sub MovableButton_MouseMove(blah, blah) Handles MyBase.MouseMove
If _Moving Then
Dim clientPosition As Point = MyBase.Parent.PointToClient(Cursor.Position)
MyBase.Location = New Point(clientPosition.X - _CursorOffset.X, _
clientPosition.Y - _CursorOffset.Y)
End If
End Sub
There's obviously more to this code, specially when you consider design-time requirements and any other "options" you want to put on this button, like picking which key combination to hold down to move the button.

The .NET framework provides a very flexible and powerful approach to databinding that cuts down a lot of redundant code and simplifies the development process significantly. Unlike the earlier databinding models, which were limited to single data source, the .NET framework provides read/write (two ways) link to a large number of data sources such as DataSets, DataTables, Collections and also textboxes, checkboxes, radio buttons and so on.
