Don't use single statement. Create a different insert statement and different update statement and execute both separately. Instead of using case in select, use where conditions, like:
insert into table (columns)
select columns
from anothertable
where ConditionsToBeMet and
update table
set columns
where ConditionsToBeMet Just make the conditions so that they define the logic you defined in case statement.

Next :confused:
Return (colBoxesOfWidgets)
End Function
End Class
Class BoxOfWidgets

Hi,
I have a ComboBox Column in DataGridView and also I use Cell Formatting event to change the Images dynamically in the DataGridViewImage Column based on business validations.
I am not able to retain the selected item value in the Combobox cell, it is disappearing because of Cell Formatting event always fires and re-instantiates the combo cell to default value.
If I disable Cell Formatting event code, I can see the value is retained in the combobox cell and it works
Please let me how to solve this issue, because I have to use Cell Formatting evetn for various conditions, So I can not disable the code.
give an idea or code sample to retain selected values in the combo cells on usage cell formatting event
Thank you
Shyam Sundar

I've done a simple custom label in .net 2.0 that allows a border color to be set. The problem is I can't get the control to repaint if another form is dragged over the control. I've tried the SetStyle() method and it doesn't seem to help.
public partial class BorderLabel: Label
{
public BorderLabel()
{
InitializeComponent();
this.SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.UserPaint | ControlStyles.OptimizedDoubleBuffer, true);
}
private Color _borderColor = Color.Black;
public Color BorderColor
{
get { return _borderColor; }
set
{
_borderColor = value;
Invalidate();
}
}
protected override void OnPaint(PaintEventArgs e)
{
base.OnPaint(e);
int borderWidth = 1;
ControlPaint.DrawBorder(e.Graphics, e.ClipRectangle, _borderColor,
borderWidth, ButtonBorderStyle.Solid, _borderColor, borderWidth,
ButtonBorderStyle.Solid, _borderColor, borderWidth, ButtonBorderStyle.Solid,
_borderColor, borderWidth, ButtonBorderStyle.Solid);
}
}
What other events should I be overriding to cause the control to repaint when a form is dragged over the control?

Change your ControlPaint to "e.Graphics":
protected override void OnPaint(PaintEventArgs e)
{
base.OnPaint(e);
int borderWidth = 1;
e.Graphics.DrawBorder(e.Graphics, e.ClipRectangle, _borderColor,
borderWidth, ButtonBorderStyle.Solid, _borderColor, borderWidth,
ButtonBorderStyle.Solid, _borderColor, borderWidth, ButtonBorderStyle.Solid,
_borderColor, borderWidth, ButtonBorderStyle.Solid);
}
Use the Graphics object you are given in the event arguments, not your own.

Thanks but what fixed it was not using the e.ClipRectangle, but using the ClientRectangle object instead.

Hello
This is one exercise in OOP lesson ,but still I am bit confuse how to get rid of small widgets, and what I want to do is when form loads it displays small widgets(<= 20) in one listbox and and rest in second listox, any help, In Public Function GetRidOfTheSmallWidgets I have put loop but it's only displays 0,1,2 so how can i add small widgets in one listbox and big ones in second listbox
Imports System.Collections.Generic

Dim colBoxesOfWidgets As New ArrayList()

You are dealing with an ArrayList that contains BoxOfWidgets instances. The ArrayList is populated with only 3 BoxOfWidgets instances: Cardboard, Metal and Metel. Each BoxOfWidgets instance has it's own internal ArrayList named colWidgets. Perhaps your intention is to iterate over the internal collections of each BoxOfWidgets:
For I As Integer = 0 To colBoxesOfWidgets.Count - 1
For J As Integer = 0 To DirectCast(colBoxesOfWidgets[I], BoxOfWidgets).colWidgets.Count - 1
lastWidgets.Items.Add(J).ToString()
Next
Next
Last, I'd also recommend using the Generic List rather than an ArrayList as it will perform better.

hello sir
Yes it works but it only displays o,1,2,3 numbers in listbox not name or length of widgets
waiting for your kind rep.
|
|
|
|

The reason you only see numbers in the ListBox is because the following loop is adding the integer I to the list box on each pass:
For I As Integer = 0 To colBoxesOfWidgets.Count - 1
lstWidgets.Items.Add(I).ToString()
Next
So, you probably want something like this:
For I As Integer = 0 To colBoxesOfWidgets.Count - 1
lstWidgets.Items.Add((DirectCast(colBoxesOfWidgets(I), BoxOfWidgets).boxType)
Next

Hello sir
thanks for your rep.
yes it works but still i am not getting all the lists for widgets like it shows box of widgets but it's not showing what's in there in each box so I have tried this and it shows how many widgets are there in each box but not name of that widgets i am getting there but still need to do some thing little to get there
so this is what i have done
For J As Integer = 0 To colBoxesOfWidgets.Count - 1
ListBox1.Items.Add(DirectCast(colBoxesOfWidgets(J), _
BoxOfWidgets).colWidgets.Add(J))
Next
so i think i need to get class widget to get name and length for each widgets but i am lost 
waiting for your kind rep.
have a nice day

I have a multithreaded application, and want to access a ListBox from multiple threads. However, if i add an item to the ListBox from a thread different from the one it was created in, the changes are only shown, once i trigger a refresh from the creation thread. Is there any way around that ?
|
|
|
|
|
|
Thanks, i also found help here[^].
|
|
|
|

Nice to see that you got it working 
|
|
|
|
|
You have to use BeginInvoke method of the control while modifying the controls' property from a different thread other than which the control was created on.

I'm trying to write a Custom Panel that draws contained controls with mixed art stuffs (rectangles, circles, triangles). I've done it very well, the problem comes when I implement double buffering. Here's my code
class BgPanel : System.Windows.Forms.Panel
{
//....
private Image buffer;
protected override void OnPaint(PaintEventArgs e)
{
e.Graphics.DrawImage(buffer, 0, i);
}
private void RenderToBuffer()
{
Graphics g = Graphics.FromImage(buffer);
foreach(Control c in Controls){
DrawArts(g); // draw some colored shapes
//********************
How do I draw each control into buffer?
//********************
DrawArts(g);
}
}
//....
}
My problem is that I don't know how to draw each control inside the panel into buffer image. Could anyone please help me with this?
I'm working on .NET CF 3.0, by the way.
Thanks,
