I found an easy way of accomplishing this. In the startup module simply put:
If Process.GetProcessesByName(Process.GetCurrentProcess.ProcessName()).Length > 1 Then Exit Sub

I have a Tab Control on my form with 4 tabs
How can I via code, default back to tab 1 or how can I default to tab 1
Any ideas?

TabControl1.SelectedIndex = 0
Selects the first tab added to the control. The index is zero based, so tab page 1 would be index 0, tab page 2 would be index 1, ...

I have a text file that was generated from a report that is in a strange format. I need to be able to convert this to a text file that can be used to import into an access database. I have no idea how to go about this and a helping hand in terms of what functions to read up on or websites (please not mdsn or google) but a tutorial on how to do this would be great.
Here is an example of what i mean.

It needs to somehow be placed in a text file that access will understand (headers and field information). Any and all help would be appreciated on this. Thank you for your help.

Well, there's the problem. There is no one tutorial to teach you how to do this. You have to read up on stuff like Reading/Writing Text Files, control-break processing, parsing strings, database creation, database access, and RegEx expressions might be helpful too. If you can find a single tutorial for all this, great! You're on your way.
But, chances are you're going to have to use Google to find multiple examples of each topic to get to know how to do each thing seperately. Then you'll have to figure out how each item will fit together to get an application that you want. This is the part that you won't find a tutorial on.
The hardest part of all this is reading a line then trying to figure out what kind of line you read. This can be minimized by closly examining your data and determining each each type of line contains so you can code some kind of recognition method. After you that, this method can then call an appropriate parser to actually get the data out of the line.

no actually i want to minimise or maximise any application window by clicking on button
|
|

I'm assuming you wanted to minimize another applications window without clicking it that window's minimize button. You'd have to enumerate through all the windows, using FindWindow, EnumWindows, GetWindowText, until you found the window that you wanted. Then after getting the handle for that window you'd have to use SendMessage to post a WM_SIZE message with a SIZE_MINIMIZED parameter, I think.

In VB.Net how can I get a value masked e.g.
Putting a date into a text box and want to make sure the following format
dd/mm/yyyy
Showing in the text box would be __/__/____ and all the user does is put in the values 01/01/2005 and no other value.
Hope this makes sense?

How to extract icon from exe file by vs.net 2005 beta 2?
In vb 6.0 , we could use API functon.
Now , how to do it?
Thanks!

The same way you do it in VB6. You just have to modify the code a bit to use the correct data types. For exmaple, a Long in VB6 is now in Integer in VB.NET.

It seems the Windows API could not use in vs.net.
The .net project only accept .net of ocx components.

Nothing could be further from the truth.
Perhaps if you posted the code you're using, a brief translation could be made?

In vb 6.0 , you could use these code:
Private Declare Function ExtractIcon Lib "shell32.dll" Alias "ExtractIconA" (ByVal hInst As Long, ByVal lpszExeFileName As String, ByVal nIconIndex As Long) As Long
total = ExtractIcon(App.hInstance, Me.CommonDialog1.FileName, -1)
For I = 0 To total - 1
p(I) = ExtractIcon(App.hInstance, Me.CommonDialog1.FileName, I)
Next I
For I = 0 To total - 1
DrawIcon Picture1.hdc, 34 * I, 0, p(I)
Next I

Declare Auto Function ExtractIcon Lib "shell32" ( _
ByVal hInst As IntPtr, _
ByVal lpszFilename As String, _
ByVal nIconIndex As Integer) _
As IntPtr
Declare Auto Function DestroyIcon Lib "user32" ( _
ByVal hIcon As IntPtr) _
As Integer
.
.
.
Dim IconCount As Integer
Dim hIcon As IntPtr
' Get the number of icons in the file. I'm not going to use it here
' but it shows how to do it. -1 tells ExtractIcon to return the number
' of icons in the file.
hIcon = ExtractIcon(Me.Handle, filename, -1)
IconCount = hIcon.ToInt32()
' Get the icon from the file into a Bitmap object. Don't forget to
' release the icon handle when you're done with it! iconNumber is a
' 0-based index into the array of icons in the file.
hIcon = ExtractIcon(Me.Handle, filename, iconNumber)
Dim b As Bitmap = Bitmap.FromHicon(hIcon)
PictureBox1.Image = b
DestroyIcon(hIcon)

how can i fix this?

You might want to try typing that EXACT error message into MSDN's search.
But, based on what you've posted so far, results[^].

Hi All
I am a new user of vb.net so i havent quite found my feet yet, the question i have im hoping a gaurdian angel can answer ASAP as i have to implement it ASAP
: I want to find out how to check the size/status of an email account eg: a user must get notification everytime a new message is recieved in their mail account(eg yahoo) so what should happen(i think) is that a query be run constantly(in loop) that will check the size of the account and if the size increases from the last state a message box should appear stating a new message recieved.
I dont want to do this through outlook but i dont know how to do it in VB HELP

email clients implementing email protocols
like pop3 which have commands to get this info
you check at interval time by using timer
Pop3 Protocol[^]

How can we check to see if a directory is empty?
I need to delete directories whenever they're empty.
E.g. <c:\example\hi.txt> If i delete the Hi.txt, the application should know that there are no more files in C:\Example, thus it will delete this entire directory as well.

Hi guys, wonder whether any of you guys have any good links to tutorials that teach you how to make our vb.net program access the notepad and enter data in it and all. Or better yet, make out program straight make a *.txt file and input data into it.. I tried searching around and couldn't find any.. Any help offered is greatly appreciated...Thanz

VB6 or VB.NET ? Either way, creating a .txt file is pretty trivial, you should google for it. Manipulating Notepad is sure the hard way to go about doing that, by a significant degree.
