How can I disable focus on few buttons?
|
|
|
|

Select your button in the form designer.
Switch "Properties" to the "Events"-Mode.
Then scroll to the "Focus"-Section and give some method name for "Enter".
I used "button1_FocusEnter".
This will create an empty method in which you put one line:
someOtherControl.Focus;
You can also prevent users from "tabbing" through your control by setting "TabStop" to false.
With the "coded" solution, the button will never keep focus, the someOtherControl will receive Focus instead.
That will not prevent anyone from pressing that button, though.
If you want users NOT to press a button, disable it.
If you set TabStop to false, the control still gets focused if someone presses it.
If you combine both ways, the button will never KEEP focus, but users can still press it and trigger it and stuff.
Cheers
Sebs

Another, perhaps easier way is to create a button that's not selectable per-se.
Create a new class InertButton that inherits Button.
In the c'tor you just add the following line:
SetStyle(ControlStyles.Selectable, false); That's it.
Use this InertButton exactly the same way you would use a regular button.

Somthing like this:
if(mybutton.Disable)
mybutton.BackColor = Color.Blue;

Im trying to support labeledit in my ListView control but
i am stuck on getting the ListViewItem object edited.
In the EventArg to EndLabelEdit there is an Item member
telling which index was edited but how do i get the ListViewItem
from the index?
listView1.Items returns the ListViewItemCollection and according
to the help there should be an Item property there but it
is not there...

Surely there must be some way of getting the ListViewItem by index without using SendMessage() ?

If I understand your problem correctly then a simple
ListViewItem theItem = listView1.Items[e.Item]; would be the answer (with e being the LabelEditEventArgs).
Can it be so simple?

{
temp = e.Start.Date;
DateTime dt;
dataGridView1.Update();
foreach (DataGridViewRow dr in dataGridView1.Rows)
{
dt = System.Convert.ToDateTime(dr.Cells[2].Value);
// textBox3.Text = dr.Cells[2].FormattedValue.ToString();
if (dr.Cells[2].Value != null && dt.Date.Month != temp.Month)
// dataGridView1.Rows.Remove(dr);
DataTable1DataConnector.RemoveCurrent();
}
}

Bind against a DataView instead. You can set the RowFilter which may or may not update the DataSet automatically. If it doesn't, one way is to assign null to the DataGrid and then assign the DataView back. You could also get the CurrencyManager from the BindingContext and call CurrencyManager.Refresh. That would be the preferred method.

You mean setting ReadOnly property.

Bind against a DataView instead of a DataSet or DataTable. You can easily create a DataView from a DataTable (just pass the DataTable to the DataView constructor) and then set DataView.AllowNew to false. Set the DataView as the DataGrid.DataSource.

I am doing an application in c# where i have 2 picture boxes.
In the first picture box i open a bitmap.
Then ,when i select a rectangle in this bitmap,the part of the image within the boundaries of the rectangle opens in the second picture box.
I cant actually open the part of the image (within the rectangle) as a separate image in the second picture box.
I used :
g=pictureBox2.CreateGraphics();
ImageAttributes remapAttributes;
ColorMap redToBlue;
redToBlue.oldColor = Color(255, 255, 0, 0);
redToBlue.newColor = Color(255, 0, 0, 255);
remapAttributes.SetRemapTable(1,&redToBlue);
g. DrawImage (globalImage,rect,zoomStart.X,zoomStart.Y,width,height,UnitPixel,remapAttributes,null,null);
but this code is giving many errors although its a copy from the one in the msdn.
please help

It seems as if you've copied the code from a C++ article, so this cannot work.
Graphics g=pictureBox2.CreateGraphics();
ImageAttributes remapAttributes = new ImageAttributes();
ColorMap redToBlue = new ColorMap();
redToBlue.OldColor = Color.FromArgb(255, 255, 0, 0);
redToBlue.NewColor = Color.FromArgb(255, 0, 0, 255);
remapAttributes.SetRemapTable(new ColorMap[] { redToBlue });
g.DrawImage(pictureBox1.Image,
pictureBox1.ClientRectangle,
0,
0,
pictureBox1.Width,
pictureBox1.Height,
GraphicsUnit.Pixel,
remapAttributes);
This is at least compilable if you have a pictureBox1 and pictureBox2 (and use using System.Drawing.Imaging; at the beginning of your code).

Hey,
has anybody tried using global hooks with WH_JOURNALRECORD or WH_JOURNALPLAYBACK in c#?
I used the class found at http://msdn.microsoft.com/msdnmag/issues/02/10/cuttingedge/ and it works fine with WH_MOUSE or WH_KEYBOARD (i have modified the code to make system-wide and it works fine).
However, once i set the hook to WH_JOURNALRECORD or WH_JOURNALPLAYBACK the system stops responding (but the mouse still works) and the system only un-freezes when i pres CTRL+ALT+DEL...i also noticed that the journal callback procedure is never called in WH_JOURNALRECORD but it IS called after WH_JOURNALPLAYBACK but ONLY when i press CTRL+ALT+DEL...anybody knows anything about this?
Thanks

var bWidth = width / 4;
window.moveTo(0,0);
window.resizeTo(aWidth,height);
window.open("Help.htm","Help","top=0,left=" + aWidth + ",height=" + height + ",width=" + bWidth + ",status=no,toolbar=no,menubar=no,location=no,scrollbars=no,resizable=no");
}
