I haven't heard of it happening. My next check would be the VS.NET installation log.

Creating only one instance of an Application

Hi all,

I was wondering if anyone knew how to create only one instance of an application. I have created a startup module to run my application but I would like to prevent the user from opening more than one instance of my application.

How would I approach this? Would I need to check for an existing process or form instance? Could someone point me in the right direction?

Any guidance would be much appreciated. Thanks.

Search the articles for "single instance" and you'll come up with a bunch of ideas. Results[^]

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, ...

Help Parsing Text file generated from Report

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.

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.

MaskedBox Query

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.

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

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 Sigh | :sigh:
