Don't make your login form the Startup form. The main form of your application should be the start form. When it starts, it should check to see if a user is logged in and, if not, show the login form.

You're going to have to reorganize this code. In your Form_Load, you can setup your applications basics and check for a user being logged in. You'll have to put something together to keep track of the users login, maybe an ID or a username.

Perhaps, set your application to not close when startup form closed, this can be found in the project properties (go to project on the main menu and select properties). Then you can say myform.close, closeing the login form once the other form is opened.

It just won't work for me!

If I use:
Me.LayoutMdi(MdiLayout.TileVertical)
Or even:
Me.LayoutMdi(System.Windows.Forms.MdiLayout.TileHorizontal)

But the tiling is a mess. Either method, I get similar results:

- two columns (three would fit more than comfortably)
- Huge gaps between the forms
- Except one column where Forms vertically overlap to fit them all in the MDI (even though autoscroll is True)

The code from the Horiz Menu choice is:

  Private Sub TileHorizontalToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TileHorizontalToolStripMenuItem.Click<br />
<br />
   Me.LayoutMdi(System.Windows.Forms.MdiLayout.TileHorizontal)<br />
<br />
End Sub

(Cascade works just fine.)

The Forms' properties are:
Autosize = False
MaximizeBox = False
MaximumSize = 168, 406

I don't want them to resize. They must remain 168,406. I had awful-looking results when I did not restrict their dimensions and they stretched out.

Can you think of any way around this? Rearranging them manually is untidy, especially as there is no "snap to grid" feature available either.

Can anyone help?

The Tile function of LayoutMDI depends on the child forms being able to resize. Tile willevenly divide up the MDI space between all the forms, then place and resize all the child forms appropriately. It does NOT consider the Maximum size properties of the children when dividing up the space.

If you want this to look good, you'll have to implent your own code to tile the child windows, taking into consideration the maximum size of the child forms. It shouldn't be very hard, it's just a little math problem involving division. You'll have to calculate the position of each form based on the maximum size that, for ease of placement, should be the same for all your child windows.

Thanks, Dave.

Pity it won't work the automatic way for me.

I will sit down and energise the brain cells for this one! It will be an interesting challenge, like some of the other ones I have faced in this project.

Saving REGISTRY Settings VB.NET

Hi .

Can anyone tell me if it's ok to write app settings like company details , logged in users , tax/vat variables . basically im wanting to find out if its ok in terms of it still being a secure location.

Thanks.

What made you think it was a secure location in the first place? The answer to your question depends on what you mean by "secure"? Are you looking to store encrypted or plain text data there? What are you doing with this information?

hi dave.

at the moment im thinking of storing plain text. my app runs mdb database and i wanted to store variables and strings saved in app settings such as
user logged in to app , tax/vat variables. i also planned to write these settings to a file which can be restored to registry if needed be. what advise can you offer on this. is it ok for me to do so and is it consider ok
practise for an app.

Thanks Dave.

From your description, you don't need to store any of this stuff to the registry. Applicaiton settings should be stored to a file in the users Application Data folder in their profile. You also don't need to store them in two different places. This will only create extra work that's unnecessary.

Dave.

Thanks I think you've confirmed and answer my question. just to confirm with you. the application settings are what the user needs to setup before using app. for example. This is a invoicing app and the user has to enter the following.

- invoice number (where they want their invoice numbering to start from)
- tax/vat (the tax or GST as wel call it in australia)
- delivery charge rate
- discount /specials rate .

so if im to store these in the user APP DATA FOLDER. can you just tell what i should be saving into in terms of FILE AND FORMAT etc. what do u recommend.
I mean do others apps also store these kind of settings in users APP DATA FOLDER. I would like to practise the standards of such programming.

Thanks again. I really appreciate you getting back to me on this

Thankyou Dave.

I will take what advice you've given me. I'm assuming it should be ok to store XML file in APPLICATION STARTUP PATH aswell.

Cheers.

Yes, in most cases. Placing it there will have the same settings for the app for every person who runs it on that machine.

Thanks Again Dave.

I feel pretty bad to ask one more thing and can appreciate you assisting many others like myself but if possible are you offer any advice or good material for creating invoice printing for VB.NET without any report utilities like crystal reports. I would like to do it in VB.NET only without any report addins.

I honestly can't thankyou enough.

Well, it's a PITA. You basically have to create you own print document and paint the data into the appropriate places on the (blank) page so they just happen to fall into the boxes on the form. This will take CONSIDERABLE trial and error to get the placements correct. You can come up with a system that accepts an offset (X and Y) from the top left corner to place each field. You then save each of these offsets to a file so you can reload them later. It's not too difficult to do, just a royal PITA to lay it all out correctly. I've seen the same thing done with fingerprinting systems (law enforcement) that print fingerprint cards to send to the FBI.

Code running from a non-local source is, by default, not trusted and runs inside a secured sandbox that limits its access to the local machines resources. Read up on Code Access Security[^] before you try and run your app from a server.

As a test, I would copy your app to the local machine and run it from there instead of the server to see what happens.

I am trying to run the program from the server, because i need multiple users from different computers the be able to access the same program. It has a database and thus the data needs to be in one place.

Dave Kreskowiak27-Dec-06 7:51

Then you better read up on Code Access Security so you know what's involved in getting this to work and what the pitfalls are.
