A very good DYNAMIC sizing routine for DataGrids if you want it
It literally requires only one line of code to attach it to any
existing Winform DataGrid, you can give it percentages like the
ASP.NET data grid and minimum column widths, the default of course is
to size all columns equally, it's very cool and the columns always
take up the full client rect of your grid making it look very
professional. I can't believe I had to write this.
Email me at dearpolycarp @ hotmail.com ... Put DATAGRID in the
subject.
I'll send you a tiny little sample with the source code, use it at
will. Tag: DataGridCell.GetHashCode() is a very bad hash function Tag: 60656
Datagrid and scrolling
My question concerns navigation with the DataGrid on my
Windows Form.
Private Sub btnNext_Click(ByVal sender As
System.Object, ByVal e As System.EventArgs) Handles
btnNext.Click
' Move to the next record
NextRecord()
' Highlight the entire row for user feedback.
grdXNew.Select(grdXNew.CurrentCell.RowNumber)
End Sub
' Move the BindingContext Position to the next record.
Public Sub NextRecord()
' The position of the binding context controls
the "current record"
Me.BindingContext(dtXNew).Position += 1
End Sub
The code seems to work fine, except that after
GrdXNew.Select is fired, the Datagrid scrolls back to the
first record. The row that was navigated to is selected,
but if it is not within the bounds of the grid, the row is
not viewable. The user would then have to scroll the
Datagrid to see what row is highlighted. It appears the
behavior is that the grid always scrolls to the top after
a selection is made programmatically.
My question is: Is there a way to maintain the highlighted
row in the viewable area of the grid?
Thank you in advance. Tag: DataGridCell.GetHashCode() is a very bad hash function Tag: 60644

Problem when changing button font at runtime
I create a simple Windows Forms application and drop a simple button
on the form with the designer. I define the Text of the button (i.e.
"Button test") and I set the button width so I have plenty of space to
display the text (i.e. 120). Then I add the following code in the
button's click handler.
private void button1_Click(object sender, System.EventArgs e)
{
button1.Font = new Font(FontFamily.GenericSansSerif, 10,
FontStyle.Bold);
}
When I click the button, the button's text is displayed with the new
Font but the last letter (t) is truncated and not displayed properly.
I can't isolate exactly the conditions in which this behavior is
produced but the above conditions produce the bug. The complete code
is below.
Any ideas on this? A bug in the button code? Any way to avoid this?

Databindings get lost on change?
I'm seeing a situation where a textBox value looses its
databinding if the value of the textBox is manually
changed. Is this supposed to happen or a bug?
To recreate:
create a simple dataset
Create a new form and add dataset and textBox and button
bind the textBoxt.Text property to a column in the dataset
NOTE: The dataset is not used in conjunction with any
other database objects
In the constructor of the form, add code to add a row to
the dataset.
In the button, change the value of the cell in the dataset
Run app and press button. notice the value appropriately
is displayed automatically in the testbox on the form.
change the value of the textbox directly
now notice pressing the button does not update the textbox
any longer.

MDI Child Form Problem
Hey guys, maybe someone can help me with some MDI issues I have. A
co-worker asked me a very simple question, one that I blew off as trivial,
and it has become a time-consuming issue.
Simply put, there is an MDIForm and a child form.
The MDIForm does the usual from within its constructor...
this.IsMdiContainer = true;
Form2 frm = new Form2();
frm.MdiParent = this;
frm.Show();
Okay, so nothing special there.
The child form then has a combobox on it. The question was, how do I get my
child form to close if I pick a particular item from the combobox. Or, to
make it easier, close the child form when the item selection changes in the
combobox.
So the following is in the child form...
private void comboBox1_SelectedIndexChanged(object sender,
System.EventArgs e)
{
this.Close();
}
Unfortunately this throws an exception indicating that the combobox has
already disposed itself and a null-reference exception is raised.
So I suggested the following...
private void comboBox1_SelectedIndexChanged(object sender,
System.EventArgs e)
{
this.Dispose(false);
}
This gets rid of the exception, but the child form is really not disposed,
even though visually it looks like it has gone away. It can be made to come
back sporadically by clicking inside the MDI parent form.
Using a true argument in the Dispose yields the same null pointer exception.
So with that, my understanding of forms went down the tubes, along with my
understanding of how the GC works and how correct implementations of
IDisposable work.
Can someone comment on how to get an MDI child form to close itself (i.e.
commit suicide)? Closing the child from a menu or toolbar on the parent
form is not a problem.
Thanks in advance.

Datagrid question
Using VS 2003, VB.NET, sql msde...
This is really a question about a winform datagridcontrol (if there is a
better newsgroup for these winform datagridcontrol questions, let me know).
A parent/child relationship exists. When you click the + next to the parent
row, the relationship name "Display Details" appears. You then click that,
and everything previously FILLed to the child DataSet table displays. All
works as expected.
My question are:
1) Is there an event triggered by clicking on "Display Details" so you could
dynamically FILL the child table at that point, instead of having to fill it
prior it "Display Details" being click? If not an event, any other way to
do it?
2) Since the child table in the DataSet is held in memory, should I be
worried about how large it might get? Can it get to large or does Windows
XP/.NET still handle it appropriately regardless of its size? In my case,
the child could get quite large, constantly being added to by the program
automatically (which is the main reason I would like to load it when needed
via #1 above).
Thanks!

Holding a form in memory
Hi All,
I have a module level form variable as I want to react to custom events that
form raises:
Dim WithEvents m_frmSearchForm As frmPartSearch_Alt
When the user clicks the search button, I carry out this code:
If m_frmSearchForm Is Nothing Then
m_frmSearchForm = New frmPartSearch_Alt
With m_frmSearchForm
m_frmSearchForm.KeepOpen = False
m_frmSearchForm.MdiParent = MyBase.ParentForm
m_frmSearchForm.CaptionText = "Component Search"
m_frmSearchForm.SearchOption =
frmPartSearch_Alt.eSearchOptions.AllowSelect
m_frmSearchForm.Show()
End With
Else
m_frmSearchForm.Show()
End If
Which basically just loads the form and shows it.
The KeepOpen property allows the form to remain open.
The searchoption property tells to allow selection.
Both of these don't affect the problem.
Now, when the user closes the form using the x button, and then clicks the
search button again to execute this code then m_frmSearchForm isn't nothing
and the m_frmSearchForm.Show() is called, however nothing appears.
Can anybody help me with this????
When the x button is used to close a form, how can I ensure that the global
variable is emptied?
I don't want to open the form using showdialog.
Thanks

Resizing an Image to fit in a PictureBox
I have a question about how to format the display of a JPEG image in a
PictureBox control. My current code is the fullowing....
Image image = Image.FromFile( strFileName );
pictureBox.SizeMode = PictureBoxSizeMode.StretchImage;
pictureBox.Image = image;
The images are loaded dynamically, and I do not have control of the size and
aspect ratio of the images. With the StretchImage mode selected, I get
some strange stretching (either vertically or horizontally, when the aspect
ratio of the image is noticably different from the aspect ratio of the
PictureBox.)
What mechanism can I use to effectively resize the image myself before
displaying it in the PictureBox? As yet I'm unable to find either a method
on the Image class or on the PictureBox class to resize the image before
display. I'd like to be able to adjust it to either fit snug vertically or
horizontally depending on respective aspect ratios.
Thanks,
and Cheers,

asynchronous programming question
Hello,
With asynchronous programming :
Why does the callback-function (running in a worker thread) may not update
the state of a control on the main-form ?
The docs say that you must use a MethodInvoker instead as in following
example :
Private Sub CallBtn_Click(ByVal sender ...) Handles CallBtn.Click
webServiceObj = New MyDatabaseWSClass()|
Dim delCB As New AsyncCallback(AddressOf MyCallBack)
aResult = webServiceObj.BeginConnectToDB(CInt(txtSeconds.Text), delCB,
Now)
End Sub
Private Sub UpdateUI()
OutputLabel.Text = "Async: Web service call complete."
End If
Private Sub MyCallBack(ByVal result As IAsyncResult)
If webServiceObj.EndConnectToDB(result) = True Then
DisplayMessage(result)
End If
' following is NOT allowed although it works fine ?????
OutputLabel.Text = "Async: Web service call complete."
Dim mi As New MethodInvoker(AddressOf Me.UpdateUI)
Me.BeginInvoke(mi)
End Sub
Any ideas ?

Closing form kills the app
Hi
I have this problem on winxp/offixexp machine but not on win2k/office2k
machines.
I have a main form which has a panel which has a child form. The child form
opens a dialog form. When the dialog form is closed using the 'x' button or
using me.close in code, the app crashes. The source the error is pointed as
my main app loop; Application.Run(frmMain) in Sub Main.
I am totally baffled by this error. Any ideas to solve this would be
appreciated. I am using vs.net 2003 with framework 1.1.
================================================
For those with a stronger heart, here is more information; I used the
Windows Debugging Tools which provided the trace but with added problem that
app crashes earlier during the opening of the child form. Here is the trace
anyhow. Thanks.

Form created or not?
Hi
I am getting my form using; frm = New frmMyForm.
How can I check if this statement has been executed? I have tried If frm Is
Nothing Then, but it does not work.
Thanks

DataGrid/ComboBox custom column problems
Hello,
I know this has been discussed a lot already because I've been searching
around for information the last few weeks.
I'm trying to implement a DataGridComboBoxColumn class. I've found
several examples on the web. They all seem to have problems, though
that I've been unable to resolve.
The most promising example I have found is at:
http://msdn.microsoft.com/msdnmag/issues/03/08/DataGrids/default.aspx
However, it has the following problems:
1) combobox selection works fine but then when you leave the cell
whatever you just selected goes away.
2) moving up and down in the data grid w/ arrow keys causes the
following exception to be thrown:
System.ArgumentException: The ListManager's position must be equal to rowNum.
Parameter name: rowNum
I've seen some comments about adding an event handler for
SelectionChangeCommited so I added the following:
private void comboBox_SelectionChangeCommitted(object sender, EventArgs e)
{
DataRowView rowView = (DataRowView) this.comboBox.SelectedItem;
string s = (string) rowView.Row[this.comboBox.ValueMember];
this.ColumnStartedEditing(this.comboBox);
this.SetColumnValueAtRow(this.cm, this.iCurrentRow, s);
}
This fixes problem #1 above but now it has a problem where the first
time you select something from the ComboBox it always selects the first
thing in the ComboBox list even if you clicked on the 2nd, 3rd or whatever.
Also, the arrow key problems are still there.
Does anybody know if there are more complete examples out there? Is
there a third party class that anybody is selling?
Also, I'm somewhat of a novice at this so if anybody could point to
some good books that have discussions of the relevant topics for
figuring this out, I'd really appreciate it.
thanks,

What is the Best way to release memory
I have an MDI application with only one top level menu. All the menu
options called child forms and are no merge menus on these child forms.
They are simple forms with various controls and other things.
Now if I create various objects in this form class, do I really need to
dispose them and set them to null before closing the form? When I close
the form and set the form to null, I assume that all the variables or
objects or events created within that form should become unreachable
anyway and should be available for GC to collect. But then when I check
using scitech memory profiler and take a snapshot before calling the
form and compare it with a snapshot after closing and setting the form
to null, I see hundreds of strings and other objects generated and never
released. If I do the same thing second time, I see the same thing again
but lot less new objects and so on......
Can someone explain me what is wrong here and what is the best practice.
My application is 24/7 kind of business app and it runs out of memory
after every 3-4 hours of continuous use.
Thanks in advance

Shift + Space DataGrid Problem, I'm really close to fixing it. Any other ideas?
OK.
As many already know, there's a problem with the datagrid when you're
typing text in a column and you accidentally type space and shift
together.
Like if I type Sam Baker, and have the shift pressed when I type the
space inbetween my two names, when the shift is really for the B.
Here's what I got so far, but there's still a weird problem. Thought
if I posted this, it might get others thinking.
I inherit the datagrid. If the user gets a shift/space then I don't
do anything and set a counter of the number of spaces needed. Then
the next time, it should tack on spaces to the next character passed.
This works if the shift is not pressed for the B, but if it is it
prints
SamB Baker. Not sure how that initial B is getting in there. Can
anyone figure it out???
The other problem, is getting the character from keyData. Below I'm
using J, but is there a way to see if there's a character in keyData.
When I do keyData.ToString I may get "G, SHIFT". Is there a way to
just get the "G" out?
In my inherited datagrid...
Private m_intSpacesNeeded As Integer = 0
Protected Overrides Function ProcessCmdKey( _
ByRef msg As System.Windows.Forms.Message, _
ByVal keyData As System.Windows.Forms.Keys) As Boolean
Dim ShiftSpace As Keys = Keys.Shift Or Keys.Space
Dim SendString As String
If (ShiftSpace.Equals(keyData)) Then
m_intSpacesNeeded += 1
Return True
End If
If (m_intSpacesNeeded > 0) Then
m_intSpacesNeeded = 0
SendString = " J"
SendKeys.Send(SendString)
Return True
End If
Return MyBase.ProcessCmdKey(msg, keyData)
End Function Tag: DataGridCell.GetHashCode() is a very bad hash function Tag: 60561
