The problem is that when the user switches away from the initial form, the first event to fire will be that the form has gotten focus, after which the form will automatically move focus to the control with the lowest tab number, or to the control that you explicitly tell it to. So if the last control to have focus should always get the focus back, you need to monitor which control (for example your textbox) has focus at any time (for example by its index or tab number).
Then you can just set focus to that control when focus is brought back to the form.
In other words, the problem hasn't anything to do with your usercontrol.
My advice is free, and you may get what you paid for.

I agree that that is what is happening with my usercontrols, But when the focus starts out in a standard text box, that is not what is occurring. In the standard text boxes (or any other windows "standard" controls). when returning to the first form, the focus returns to where it was when we left the form automatically.
For example, a form with three controls, two textboxes, TabIndex 1 and 3, and my UserControl tab index 2
Tab Index 1 -> Jump off and return -> Tab Index 1 (as expected)
Tab Index 2 -> Jump off and return -> Tab Index 1 (the questionable one)
Tab Index 3 -> Jump off and return -> Tab Index 3 (doing what I want my control to do)
Also I have tried code to monitor what the last selected control was, and to reset it using OnEnter and OnLeave functions, but Even though it was doing LastControl.Focus() on the correct LastControl the focus was still ending up back at TabIndex 0 as if something else in the application was forcing it to go there for some reason. But even with every other reference to "Focus" in my code commented out, it still kept going back to 0. (Also in my basic test case that I created with out any other code in it, just standard controls and the absolutely fewest lines of code to make the forms show up.
Does anyone have an example of tracking the last control used? I could easily be doing something wrong, but with the time I have spent on this, I don't think so.

For those people looking through the archives and finding this. I ended up changing my UserControls into Panels. It comes with its own issues. But seems to have "fixed" the listed problem.

can anyone point me in a good direction. I am upgrading an old VB6 app. There are two primary forms. If I hide a form, then unhide it, it seems to change size. Any idea why this is or how I can stop it? (I generally show only one of the two forms at a time)
I do have a way to determine what size it needs to be but am not sure where to put my re-sizing routine (the form needs to be different sizes for different configurations) It is generally resized on the load event.
Thanks in advance
sorry, upgrading a VB6 app to .net, did not have issue in VB6

Your best way to do this is to write both forms as controls, and then show/hide those on the same form. Having said that, there's no reason for yuor form to resize, you should post some code.
No-e wrote: I do have a way to determine what size it needs to be but am not sure where to put my re-sizing routine (the form needs to be different sizes for different configurations) It is generally resized on the load event.
I assume this means your load event is firing every time, have you tried breakpoints ? Does it need to be resized regularly, or only on startup ?

Thanks for your response, if I might take a step back it may help as I also see this screen resizing when the form loads.
Private Sub frmChamber_Load(ByVal eventSender As System.Object, ByVal eventArgs As System.EventArgs) Handles MyBase.Load
frmChamber.DefInstance.Height = frachamber(0).Height + 214
If frmChamber.DefInstance.Height < fraControl.Height + 200 Then frmChamber.DefInstance.Height = fraControl.Height + 214
end sub
when this code runs, my height will be 645 in this case. It is very clear.
the code then returns to the
public sub new() routine and does a me.show(). Note this code was inserted by the update tool,I have not changed it, copied exactly as is)
Public Sub New()
MyBase.New()
If m_vb6FormDefInstance Is Nothing Then
If m_InitializingDefInstance Then
m_vb6FormDefInstance = Me
Else
Try
'For the start-up form, the first instance created is the default instance.
If System.Reflection.Assembly.GetExecutingAssembly.EntryPoint.DeclaringType Is Me.GetType Then
m_vb6FormDefInstance = Me
End If
Catch
End Try
End If
End If
'This call is required by the Windows Form Designer.
InitializeComponent()
'This form is an MDI child.
'This code simulates the VB6
' functionality of automatically
' loading and showing an MDI
' child's parent.
Me.MdiParent = MBIG.mdiMain.DefInstance.DefInstance
MBIG.mdiMain.DefInstance.DefInstance.Show()
'The MDI form in the VB6 project had its
'AutoShowChildren property set to True
'To simulate the VB6 behavior, we need to
'automatically Show the form whenever it
'is loaded. If you do not want this behavior
'then delete the following line of code
'UPGRADE_NOTE: Remove the next line of code to stop form from automatically showing. Click for more: 'ms-help:
Me.Show()
End Sub
The form will then show on screen but will be much shorter than it was when I set it. I can re-size it again from the calling routine, but I am not sure why it would change.
Thanks for your help, I am hoping I am just not understanding how this works.

I had a similar issue with minimizing. When minimized and then unminimized it changed it's width to a very small number. You can stop this from happening by putting code in the activate event and setting the minimiumsize property.
Example:
If _SizeAtLoad = -1 Then 'don't want to do this everytime it activates, just first time
_SizeAtLoad = Me.Width
'* Changed to avoid "repaint" flicker and bounce
Dim MinWidth As Integer = _SizeAtLoad '* default to width when form opens (backward compat. behavior)
Dim MinHeight As Integer = 300 '* default to 300
If Me.MinimumSize.Width > 0 Then
MinWidth = Me.MinimumSize.Width
End If
If Me.MinimumSize.Height > 0 Then
MinHeight = Me.MinimumSize.Height
End If
Me.MinimumSize = New System.Drawing.Size(MinWidth, MinHeight)
End If
Hope this helps...

Thanks, glad to see I am not the only one  I also found the visible changed event and put my resizing there. Kind of strange, would like to understand it better but will need to move on now....

Hi,
I am trying to print a pdf using the printdocument and printdialog by passing a file name using the opendialog. This is my code
im c1 As OpenFileDialog = New OpenFileDialog
c1.InitialDirectory = "c:\"
c1.Filter = "PDF Files (*.pdf)|*.pdf"
If (c1.ShowDialog() = DialogResult.OK) Then
lblFileName.Text = c1.FileName
file = lblFileName.Text
End If
PrintDocument1.DocumentName = file
PrintDialog1.ShowDialog()
PrintDocument1.Print()
Anytime I try this it does not print anything.
Can anyone help please

There is no PDF support in .NET. You need to buy a third party library for that. The print dialog DocumentName in general, does not magically print a document for you in any case. You need to impliment printing in all cases. Perhaps you should try reading some documentation ?

I recently upgraded a project that did a lot of screen manipulation. Controls (hundreds in different configurations were loaded, aligned and displayed using the ".left" and ".top" commands on the control.
In many places there were alignments done based on other things and an offset, for example,
frachamber(0).Width = ((ID_WIDTH * 2) + (SLOT_WIDTH * 2) + 400)
after the upgrade I get
frachamber(0).Width = VB6.TwipsToPixelsX((ID_WIDTH * 2) + (SLOT_WIDTH * 2) + 400)
I would like to simplify and get rid of the twipstopixels and just go with pixels but am not sure how to convert my offset values (400 in this case) It looks like someone spent a lot of time figuring out all these offsets in the past, something I would like to avoid if possible.
any idea how to convert, say 100 twips is about this many pixels? (I guess they would be needed in both X and Y). In debug mode it will not tell you what the converted value is in pixels.
Thanks
sorry, upgrade from vb6 to .net

That is how it is supposed to work. Is it not doing that?

I have a task that i have to synchronize/update both my web(asp.net & SQL 2005) and windows application databases(VB.net & SQL 2005).
My scenario is my web app. and windows app. both accept reservations. I want any reservation happen to my web or windows app will reflect to both databases(online & local) at the same time.
Please help me.
Thanks.

I would look at using SQL Server replication or if that is not possible, writing INSERT, UPDATE and DELETE triggers for each of the tables that need syncronising. Better still why not use the same database for both apps?

Like Steven said, best is to use a single database for both. In fact, it is useless to build a separate windows form. Just make a separate section in your web app with login for administrators / employees, and build the form there.
Using xml could be an alternative approach. Handle web reservations as orders, and have your web app send the necessary information for the reservation in an xml file.
Vice versa, you can send data about existing reservations / open capacity in xml files to your web server.
Obviously this approach would not nearly be as real-time, so you would have to figure out a rule about how to handle double reservations. For example an approval queue.
My advice is free, and you may get what you paid for.

Single database will do and write a webservice which handles database layer and business logic layer. Webservice can be called from web and windows applcation. So even if you change the presentation layer (web or windows) you can do that.

You have asked two questions.
1 - output to notepad. I assume you mean output to a text file ? File.WriteAllText will do that. Process.Start will open the file in notepad.
2 - formatting your data. Your best bet here may well be to read your data, then iterate over it and build the format you want, given that you have to build it into a string to save it in the first place.

Use a select statement (query) or stored procedure to open up a datareader, then open a connection to a text file using the filesystem object. Use a loop to read through the datareader and append a line to the text file for each item you want.
Here's the pseudo code - you fill in the rest.
Open datareader
Open file for Append
do while not datareader.eof
file.write("Name: " & datareader("Name"))
file.write("Designation: " & datareader("Designation"))
file.write("Salary: " & datareader("Salary"))
file.write("------------------------")
loop
file.close
datareader.dispose
