noticed the strange behavior of Databinding to ToolstripComboBox.Combobox when it is being added to ToolstripDropdown or Contextmenu. Normally I'm binding SQL data to ToolstripcomboBox.Combobox by following code.
Me.tspcbxTest.ComboBox.ValueMember = "ID"
Me.tspcbxTest.ComboBox.DisplayMember = "Column_to_Dispaly"
Me.tspcbxTest.ComboBox.FormattingEnabled = True
Me.tspcbxTest.ComboBox.DataSource = Me.Table1BindingSource
Me.Table1TableAdapter.Fill(Me.DataSet1.Table1)
Though it works perfect on ToolstripcomboBox(es) on ToolStrip or MenuStrip, failed on ToolStripSpiltButton (or) ToolStripDropdown (or) Contextmenu.
Thanking in advance.
Please!

I was just going through your snippet. I just wonder, did not you put something like below to bind.
<> is used as place holders.
this.tspcbxTest.ComboBox.DataBindings.Add(new System.Windows.Forms.Binding("SelectedValue", <datasource>, "<valuefield>", true, System.Windows.Forms.DataSourceUpdateMode.OnPropertyChanged));
|

|
|

try this
Me.tspcbxTest.ComboBox.BindingContext = Me.BindingContext
Me.tspcbxTest.ComboBox.ValueMember = "ID"
Me.tspcbxTest.ComboBox.DisplayMember = "Column_to_Dispaly"
Me.tspcbxTest.ComboBox.FormattingEnabled = True
Me.tspcbxTest.ComboBox.DataSource = Me.Table1BindingSource
Me.Table1TableAdapter.Fill(Me.DataSet1.Table1)

Hi Infarkt!
Much appreciate for your advice. 
I didn't notice that I've to assign it's binding context, that wasn't require in WinForms ComboBox.
Finally I solve the problem with following snippet.
Dim cb As ComboBox = DirectCast(tspcbxTest.Control, ComboBox)
With cb
.BindingContext = Me.BindingContext()
.FormattingEnabled = True
.DisplayMember = "Column_to_Dispaly"
.ValueMember = "ID"
'I declared new BindingSource so it doesn't relate to another control(s) with same BindingSource
Dim bs As New BindingSource(Me.Table1BindingSource, "")
.DataSource = bs
bs.Sort = "Column_to_sort_1,Column_to_sort_2,blah,blah"
Me.Table1TableAdapter.Fill(Me.DataSet1.Table1)
bs = Nothing
Thank you.

For a little WinForms application I'm working on, I have a grid of Buttons and I want to be able to press and hold the left mouse button and as the mouse is moved from Button to Button I want the Buttons it crosses to receive mouse events (kinda sorta like in MineSweeper). But I find that the Button I start on captures the mouse.
So far I have written a handler for the MouseCaptureChanged event that will set Capture to false if it has become true and it works pretty well.
private void
DeCapture
(
object sender
,
System.EventArgs e
)
{
System.Windows.Forms.Control temp = sender as System.Windows.Forms.Control ;
if ( ( temp != null ) && ( temp.Capture ) )
{
temp.Capture = false ;
}
return ;
}
However, it seems like I should be able to set the Button so that it won't capture the mouse in the first place; is there a way to do so?

I do not know of a property or method of button that will allow you to turn mouse capture off. Although obviously now that I have said that someone will come along and tell you about one!
Apart from the method that you are currently using, the only way I can think of is to use faux buttons on a panel or usercontrol with a GetButtonAt(x, y) method and do the drawing of pressed/unpressed state yourself in response to OnMouseMove, OnMouseDown, OnMouseUp etc.
There was (back in the VS2003 days) an MSDN Sample called ButtonArray Sample that did something similar.
There still is! Found it here[^].
Hope this helps.

Hi Guys,
I have an Installer object in a program, and i'd like to do some configuration to the installed files during the install process. In order to do this, i need the root directory of the installation, as specified when it prompts the user to enter the path of the install.
Is there any way to get this from inside the Installer? Or do i need to pass in a parameter or some kind of configuration setting?
Regards
Tris

Have a look here[^]"> and here.[^]"> Probably it would be best to use the Installer class.

In the AfterInstall event of an Installer class you can get it from here...
System.Reflection.Assembly.GetExecutingAssembly().Location

Hi all,
This should be simple, but I can't figure it out.
How do I check if an mdi child is already open?
Here's what my app does
1. User clicks on button1, child1.show()
2. User clicks on button2, child2.show()
3. If user clicks on button1 again, I want to have a msgbox saying child1 is already open. But I need to check first if it is open or not.
How do I do this?
Thanks a lot!!

Check the MDIParent's MdiChildren property.

How about something very simple, like setting a flag when you create an instance of the child form and show it? Then you code can just check that flag to see if the form is already open. When the form closes, reset the flag.
|
|

I suspect you're trying to ensure that you don't open multiple instances of the same mdi form i.e. you want to check if an instance is open and if it is not, you open it otherwise you show the already existing instance. If that is that case, lookup singletons
e.g http://msdn.microsoft.com/en-us/library/ms998558.aspx[^]

And why are you telling me this?? Try replying to the original poster next time and not someone else giving an answer. That way, he gets the email that says you replied to him. Right now, he doesn't know you replied at all.

No need to go ballistic. Twas just a mistake. I intended to reply to the original posting. Do you usually go off on simple things like that? Take a pill and chill!

If you think that was me going off on you, you haven't been around here long enough.

Example of two buttonclicks in the MDIParent:
private void button1_Click(object sender, EventArgs e)
{
bool open = true;
foreach (Form frm in MdiChildren)
if (frm.GetType() == typeof(Form1)) open = false;
if (open)
{
Form1 frmOne = new Form1();
frmOne.MdiParent = this;
frmOne.Show();
}
else
MessageBox.Show("Form1 is already open");
}
private void button2_Click(object sender, EventArgs e)
{
bool open = true;
foreach (Form frm in MdiChildren)
if (frm.GetType() == typeof(Form2)) open = false;
if (open)
{
Form2 frmTwo = new Form2();
frmTwo.MdiParent = this;
frmTwo.Show();
}
else
MessageBox.Show("Form2 is already open");
}

I want to assign a stored procedure for an sql datasource. The stored procedure belongs to different user-defined schema rather than the dbo. The stored procedure is being detected but but when I click test it says "Could not find stored procedure 'sp_name'".

Hey dude, are you aware you posted this in the .NET framework forum? Seems like it should be in one of the Database forums yes?

First i ve created .xsd file and then add to my project. After that add a crystal report. I am not getting any table in the Database field of the crystal Report and getting error "The Report has no Tables"
<pre> Public Sub sPrintProjectExpenseReport(ByVal Print As Boolean, Optional ByVal findstring As String = "")
Dim ObjDataAdapter As SqlDataAdapter
Dim ObjDataset As DataSet
Dim sql As String
Try
sql= "Select * from project"
ObjDataAdapter = New SqlDataAdapter(sql, ObjCon)
ObjDataset = New DataSet()
ObjDataAdapter.Fill(ObjDataset, "ProjectwiseExpenseReport")
''''export xsd
'ObjDataset.WriteXmlSchema(Application.StartupPath & "\ProjectwiseExpenseReport.xsd")
'MsgBox("Report Exported")
Dim ObjReport As New CRProjectwiseExpense
ObjReport.SetDataSource(ObjDataset.Tables("ProjectwiseExpenseReport")) '' error is here
If Print Then
ObjReport.PrintToPrinter(1, False, 0, 0)
Else
FrmCRViewer.ObjReportViewer.ReportSource = ObjReport
FrmCRViewer.Show()
End If
Catch ex As Exception
MsgBox(Err.Description, MsgBoxStyle.Critical)
End Try
End Sub
|
|
|
|

First assign the report like generate report by Datasource
then
Set all the data source by programmatic
it will start work
