Printing Programmatically using ReportViewer Control
I've built a report using the ReportViewer control in a Windows application
(VS2K5). With a timer control, I want to be able to programmatically output
it to a printer. FYI, I really rather not use a document control.
Can anyone point me in the right direction?
Thanks.

Something like the P/Invoke call GetForegroundWindow(), but I want it

top of the others.
Any ideas?

BackgroundWorker and ListView cross-thread exception
Hi,
I am writing an application which displays a list of computers on a network
and then pings each one and displays the result.
To keep the UI responsive, I am doing the ping operation using a
BackgroundWorker component. The Ping method loops through a list of Computer
business objects, pings the name of the computer and stores the result in a
property of the Computer object called Result.
The Computer object also implements INotifyPropertyChanged interface, which
raises a PropertyChanged event when the Result property is modified.
I have an event handler in my form class which listens for the
Computer.PropertyChanged event, and attempts to update the corresponding
ListViewItem with the result of the ping.
However, as soon as I reference the ListView control, or any of the items, I
get:
Cross-thread operation not valid: Control 'ComputerListView' accessed from a
thread other than the thread it was created on.
How can I ensure the ListView gets updated?

Toolbars change locations
I am building a Windows Forms application in .NET 2.0 using VS 2005. The
application has a menu strip and a tool strip control at the top of the
form. The bottom of the form contains two status bars. I have found that
when I build my Release version and distribute it that others using the
application start it up and the toolbars and status bars change location.
For example the Toolstrip appears above the menu strip control, even though
in my code the design is explicitly set so that the menu is on the top and
the Toolstrip is below it.
I have tried setting the locations manually in the code.
I have tried removing the controls from the controls collection and
explicitly adding them back to the controls collection in the order that I
wish them to appear.
Still, regardless of what I do the toolstrips move. Is there a way to
"lock" down the toolstrips so they stay where the designer (me) has put
them? It looks extremely unprofessional to open an application and have the
toolstrips appear above the menu.
Thanks,

Textbox input from a customized location
Hi,
Environment : VS 2005 / .NET 2.0 / Windows XP SP2
Requirement :
class MyTextBox : TextBox
{
// more code
}
When I run the application my text box caret blinks in its usual place ( at
the left ).
I want the cursor to be X pixels from the left of the text box and hence
the user can only enter data from that location.
I tried with SelectionStart += X pixels -- it did not work
Then I pinvoke SetCaretPos(X, Y ) - showed up the caret position properly.
Problem :
Though the caret position shows up properly, when I type text within my text
box, the text is taken from the 0th location .
How can I force the user to enter data from the X th location where the
cursor is placed .
NOTE : I have handled OnPaint to do some graphics drawing inside the
textbox... dont think this has any relevance with this query ; just FYI if
something is linked up to this .
Thanks in advance .

Checkbox and selectnextcontrol
When selecting a Checkbox using the SelectNextControl() method, i've noticed
that the checkbox does not display the focus rectangle.
By writing a simple application with a button and two checkboxes (where the
checkboes have a tab index value greater than the button's), invoking the
SelectNextControl() method from the button click event handler, silently
moves focus to the first checkbox, but no focus rectangle is displayed.
Pressing TAB once, moves the focus to the second checkbox, which can be seen
as the focus rectangle IS displayed.
Any suggestions on how to get the focus rectangle to display for a checkbox
when using the SelectNextControl() method to move to it initially? Tag: Auto-arrange in data designer Tag: 116004

"Locked" controls?
Hi everybody,
in a VB.Net (VS 2005) application, there is basically three "states" in
which controls are to signal what can be done with them. Usually, values
loaded into controls may be looked at, but not edited ("Locked"). In
certain cases (simplest: user has the permission to change data), controls
allow changing their contents. While certain operations are being carried
out, controls are completely disabled (i.e. the form itself has its
Enabled-property set to <False>).
Thus I need a way of at least visually distinguishing between <.Enabled =
False> and i.e. <"Locked" = True>. The easiest way would be to have
controls appear exactly as the <.ReadOnly> property does - the controls'
background appears grayed out, but the forecolor remains black. This also
enhances readability and copying text or seeing the tooltip is also
possible.
Too bad this property can only be found in some controls but not even for
some the most usual ones, i.e. TextBox and DataGridView have it, but
ComboBoxes and DatePickers don't.
The <EnabledChanged> event didn't help either, as setting the forecolor of
the resepective control seems to not be considered when the control is
disabled.
Any idea how I could realize something like a <ReadOnly> appearance for
controls that themselves do not publish that property?
Cheers & TIA,

Getting benefits of Application Framework while using Sub Main for
I have an application that uses Sub Main as the Startup Object.
However, there are certain features available when enabling the
Application Framework (e.g. specifying splash screen, single instance
application, application-level events, etc.) that I have forfeited by
doing this. I'm not sure why one can't have a Startup Object of Sub
Main when enabling the Application Framework, but I'm sure there's a
good reason. So, here are my questions:
Right now the only thing I'm doing in the Sub Main is 1) creating some
global objects that will then be available to all forms, etc. in the
application, and 2) loading a login form where the user can login. I
then check to see if login was successful, and run the application if
it was. Here's the code:
<STAThread()> Public Sub Main()
CreateGlobalObjects()
' Let user attempt to login
Dim login As LoginForm = New LoginForm()
login.ShowDialog()
If (login.DialogResult = DialogResult.OK) Then
Application.Run(New MainForm())
End If
End Sub
QUESTION 1: Is there a way that I could accomplish the same thing but
do it using a form (LoginForm I'd presume) as the Startup Object?
QUESTION 2: What are the good reasons to use Sub Main rather than a
form as the Startup Object?
QUESTION 3: If I can't do the same thing using a form as the Startup
Object, how could I 1) implement a Splash screen, and 2) limit
application to single instance, bringing up existing instance if user
tries to run again? Tag: Auto-arrange in data designer Tag: 115995

datagridview binding and object properties
Suppose I have an object that looks like this:
public class thing
private mOne as string
private mTwo as string
private mThree as string
private mFour as string
public property one as string
bla
end property
(and so on, public properties for the others)
end class
then I make a List(of Thing) and add a bunch of instances
then I bind the list to a datagridview
It's not possible for me to make the properties private
My problem is that I only want to display properties One and Two in
the grid view. I want Three and Four around to help out with sorting
and data type conversion, but I don't want to display them in the
grid. Currently, I just remove the columns programmatically. But
what I really want is to decorate the properties with attributes that
affect which properties appear in the grid. Does such an attribute
exist?

Can't see textbox control
This makes not sense at all.
I created a textbox on my screen and set the name property to "Status".
If I double click on the textbox, it goes to the code page and shows:
private void Status_TextChanged(object sender, EventArgs e)
{
}
So obviously, it sees the object.
But in my code I have:
Status.Text += String.Format("Opening
{0}\n",Path.GetFileName(strFile));
And I get the following error:
An object reference is required for the nonstatic field, method, or property
'FileProcess.'FileProcess.Status'
How can that be????
In my FileProcess designer page I have:
private System.Windows.Forms.Button button1;
private System.Windows.Forms.TextBox Status;
private System.Windows.Forms.Label label1;
So obviously the object is there.

Padding problem
I'm experiencing a problem with a client that I have never seen. When I
receive code (windows forms) from him there is no .Margin = new System.
Windows.Forms.Padding(3,2,3,2) command. I can view the form in the designer
just fine, but when I compile and run the form doesn't correctly. Some of
the controls (mainly buttons) will be placed off the visible area. If I edit
the form, all of the locations change because my version of VS will add the
Margin assignment in. If I send it back to him, the same thing happens and
he can't see everything.
We are both using VS 2005 with all updates applied (that I am aware of at
least).
Has anyone seen this before, or is there a setting that I'm just not aware of
to default the padding.

an application that will be developed on .NET framework. Some people on our
team have experience with application frameworks in Java and FoxPro, and

Strata Frame, etc
I've never used any app frameworks, so My question to you is have you every
used any of these or other frameworks, what was your experience like? Can
you recommand a good framework? Do application frameworks really make your
life easier and cut down the development time, or do they just introduce
more complexity and issues dealing with someone else's code and bugs? Tag: Auto-arrange in data designer Tag: 115957
Disable MDIChild's Restore Button
I would like to disable the restore button (either make it non-
clickable or hidden) in an MDIChild. However, I want the form to be
maximized first (by code WindowState = FormWindowState.Maximized)
before the form is shown. I also want the user to still be able to
close the window by clicking the X.
I have been able to achive this by the following:
frm.MdiParent = MasterForm.MdiParent
frm.MinimizeBox = False
frm.MaximizeBox = False
frm.Show()
frm.WindowState = FormWindowState.Normal
frm.WindowState = FormWindowState.Maximized
However, this causes the form to "flash" in a normal state and then
maximize. If I just set the min and max properties to false the state
to maximized and show the form, the button is still available to be
clicked. Its only when the code happens in the above order that I have
gotten it to work.
I don't mind intercepting API messages to accomplish this.

Minimize + NotifyIcon
Thanks in advance for any assistance.
I'm developing a "panic button" application where the user single
clicks on a notify icon to activate a window, then clicks on a button
to send a broadcast to connected clients, then I minimize the form to
hide the notification.
The issue is, when the form is minimized after clicking the button to
send the notice, it docks itself, albeit minimized, above the start
menu. The intent here is to have no evidence on the users desktop that
a call for help has been sounded.
If I Hide the form instead of minimize, the form isn't visible on
subsequent clicks on the NotifyIcon. Is there a way to return the form
to it's original "hidden" state?

Dear Dr Lodha,
I had significant pain when starting urine therapy.
Now, please consider this logically ---------------- the body needs

So Dr Bhavasar's treatment is good.
What is amazing about Dr Bhavasar is that I know him for 6 years and
he has NEVER NEVER asked me for money. His treatment is consistent
and based on Rig Vedic and Atharva Vedic and Ayurvedic knowledge.
If you consult him, u can understand enough to let everybody go thru
recharging the body
with urine therapy WITHOUT PAIN.
He has told me once to do the butter-sugar-water or ghee-sugar-water
treatment BEFORE the urine-drinking in the morning.
When I was in pain, he told me to STOP the urine drinking (he is
against it) and eat butter-sugar-water in the morning on an empty
stomach (first thing) and then do ghee-sugar-water treatment 6 times
a day and then butter-sugar-water treatment in the night. It worked
to remove the depression/pain.

ACCURATE advice over the phone), learn some things from him and help
your patients using his space-time-motion treatment too.

I have a small app with bound controls that do not seem to be copying across
the data entered into them to the underlying row for the update. This one
really has me stump even though these are very simple steps and I can't see
where I am going wrong. Any help would be appreciated.
The relevant code goes as follows;
Binding controls
Dim db As System.Windows.Forms.Binding
ds = MyDataset
db = New System.Windows.Forms.Binding("Text", ds.Clients, "ID")
txtID.DataBindings.Add(db)
db = New System.Windows.Forms.Binding("Text", ds.Clients, "Company")
txtCompany.DataBindings.Add(db)
db = New System.Windows.Forms.Binding("Text", ds.Clients, "Address")
txtAddress.DataBindings.Add(db)
bmCompanyDetails = CType(BindingContext(ds, "Clients"), CurrencyManager)
Adding a new record;
ds.Clients.Clear()
bmCompanyDetails.AddNew()
Some data is entered in the Company and Address bound fields by user and
Save button is pressed to save as below;
Focus()
bmCompanyDetails.EndCurrentEdit()
Row = DirectCast(bmCompanyDetails.Current, DataRowView).Row
If (Row.RowState = DataRowState.Added) Then
' Row.Item(5) = "Test column 5" ' if this line is un-remmed this data is
stored in datatable so update is working
daCompanies.Update(ds.Clients)
End If
The Clients table is an MS Access table with ID set to Random Auto number.
Thanks

DataGridView Column Headers from First Row of Excel DataTable
I'm sure this is something ridiculously simple or just not possible
without custom coding:
How do I tell a DataGridView NOT to create column headers from the
first row of a data table using an Excel datasource?
All I want to do is have the first row of data from the Excel
worksheet be the first row of data in the DataGridView and NOT be the
column headers.
It would seem to be something simple to ask, but for the life of me, I
cannot find out how to do it. Even in Excel itself, it has a "first
row contains column headers" when importing data. Surely the
DataGridView should let me turn off that kind of feature?
Thanks in advance. Tag: Auto-arrange in data designer Tag: 115898
How SQL Express works with an application
Let's say I build an app which includes a new sql Express database. I build
the database and it's a totally independent .mdf file
When it's distributed with the database file, does the end-user need to have
SQL Express installed on his computer, or will the application work with the
database, just like it would, if the database was MS Access? Tag: Auto-arrange in data designer Tag: 115895

Concurrency error deleting record with vs 2008 generated code
Hi
I have a very simple db app that was created by dragging a couple of fields
onto a windows form. No additional code was added. The problem is that app
gives a concurrency error while deleting a record even though no other user
has access to the app.
Steps to create problem
1. Create an access table Clients with only two fields; ID Auto number and
Company: Text(50).
2. Make a connection to the access db in vs2008 and add the data source to
the connection.
3. From data source, drag the fields ID and Company onto a windows form.
This will create the binding source, binding navigator etc.
4. Click on new (+) icon on toolbar to create a new record.
5. Type XYZ in Company text field and click on Save (disk) icon on toolbar
to save the record.
6. Click on Delete (x) icon to delete the record and then Save icon on
toolbar to save the record deletion.
At this point the error is generated with the stack trace given at the end
below.
What is the problem and how can I fix it?
Thanks
Regards

Hi
If I remember correctly previous versions of vs had some sort of arrange
icons command but I can't seem to find it vs2008? What am I missing?
