go to http://www.w3schools.com/xquery/default.asp
and read XQuery
The best way to explain XQuery is to say that XQuery is to XML what SQL is to database tables.
XQuery was designed to query XML data.
XQuery is also known as XML Query.

Hi all,
I think it's quite easy to delete single selection of rows in a listview.
I usually do this :
DELETE FROM Purch WHERE PurchID
LIKE '" + lvPurch.Items[lvPurch.FocusedItem.Index].SubItems[0].Text + "' "
I wonder how to delete multiple selection of rows in a Listview Control ?

Try with this Code:
int CMultipleRowDeleteView::DeleteSelectedRowsFixed(void)
{
int nSelRows = GetListCtrl().GetSelectedCount();
if(!nSelRows)
return(0);
int* pnArrayOfSelRows = new int[nSelRows];
if(!pnArrayOfSelRows)
return(0);
int nTemp = nSelRows;
POSITION pos = GetListCtrl().GetFirstSelectedItemPosition();
int i = GetListCtrl().GetNextSelectedItem(pos);
while (i != -1)
{
nTemp = nTemp-1;
pnArrayOfSelRows[nTemp] = i;
i = GetListCtrl().GetNextSelectedItem(pos);
}
for(int j=0; j < nSelRows; j++)
{
GetListCtrl().DeleteItem(pnArrayOfSelRows[j]);
}
delete(pnArrayOfSelRows);
pnArrayOfSelRows = NULL;
return(1);
}
Hope this will Help you.

;Pfirst you need to get the selected rows :
object a = ListView.SelectedRows....
then you can delete it by calling the method Remove(); :
a[0].Remove();
if it's not working, so try :
a.Clear();
GoodLuck

    Hi All,seems a great challenge,until now seems no one of some senior programmers in big consulting companies found a solution.
Problem:
We've got a complex User control, which is organized in 5 classes:
Shape
Corner
Color
Designer
UiTypeEditor
in "Color" we've got around 20 Properties indicating Different Brushes properties based on fixed value ranges.(PathBrush Distance from Center,a
Linear Gradient property based on an Enum which let User choose only stepped values as "Top,TopLeft" etc. as position for colors..)
We got in Corner,something similar to "Color class" in which we define all proportions and values only for having an independent object which act
as corner for a rounded rectangle.
In the "Shape Class" we have finally a Graphics access with the method for creating and colorizing our Graphic UserControl.
We reached the ability to Have a "Color" Category in PropertyGrid,but ONLY using all I explained in first class in file.
We tried using PostFilterProperties driven by a "FillingType" property(PathGradient,LinearGradient,Solid etc..)If we select from one of those values
we're able to show ONLY needed properties for type selected.(Ex. If Master Property is set to "Solid Fill Type",then Properties under It will be only
Color Solid and Transparency(Alpha)....If We select "LinearGradient",all Solid Fill Values disappear and appear in propertygrid ColorGradientA and ColorGradientB and so on for textureFill etc..)All that Works but:
For viewing result of switching we need to dispose control and re-drop from toolbox,we are NOT YET ABLE to expose to property grid something is coming
from other classes in same namespace(We got ALL Geometric values and methods in "Shape Class" and we would like to "pass" as fillpath(argument)
Our FillType selected by PropertyGrid.We tried Invalidate(),Refresh(),but nothing,and ever with First class.We would like to be able to
public class Shape
{
/// only generic snippet here for example...
public int var;
public int CornerRadius
{
get{...}
set{...}
}
}
//here real snippets
public class Color
{
public static string[] PropertiesToRemove = new string[13];
public enum FillTypeEnumerator
{
Solid,
LinearGradient,
PathGradient,
Texture
}
FillTypeEnumerator FillTypeValue = FillTypeEnumerator.Solid;
[Category("Color")]
public FillTypeEnumerator FillType
{
get { return FillTypeValue; }
set
{
FillTypeValue = value;
switch (FillTypeValue)
{
case FillTypeEnumerator.Solid:
PropertiesToRemove.SetValue("LinearGradientTransparencyA", 0);
PropertiesToRemove.SetValue("LinearGradientTransparencyB", 1);
PropertiesToRemove.SetValue("LinearGradientColorA", 2);
PropertiesToRemove.SetValue("LinearGradientColorB", 3);
PropertiesToRemove.SetValue("LinearGradientPositions", 4);
PropertiesToRemove.SetValue("PathGradientCenterColorTransparency", 5);
PropertiesToRemove.SetValue("PathGradientCenterColor", 6);
PropertiesToRemove.SetValue("PathGradientSurroundColor", 7);
PropertiesToRemove.SetValue("PathGradientSurroundColorTransparency", 8);
PropertiesToRemove.SetValue("PathGradientFocusDistance", 9);
PropertiesToRemove.SetValue("PathGradientCenterPosition", 10);
PropertiesToRemove.SetValue("TextureImage", 11);
break;
case FillTypeEnumerator.LinearGradient:
PropertiesToRemove.SetValue("SolidTransparency", 0);
PropertiesToRemove.SetValue("Solid", 1);
PropertiesToRemove.SetValue("PathGradientCenterColorTransparency", 2);
PropertiesToRemove.SetValue("PathGradientCenterColor", 3);
PropertiesToRemove.SetValue("PathGradientSurroundColor", 4);
PropertiesToRemove.SetValue("PathGradientSurroundColorTransparency", 5);
PropertiesToRemove.SetValue("PathGradientFocusDistance", 6);
PropertiesToRemove.SetValue("PathGradientCenterPosition", 7);
PropertiesToRemove.SetValue("TextureImage", 8);
break;
case FillTypeEnumerator.PathGradient:
PropertiesToRemove.SetValue("LinearGradientTransparencyA", 0);
PropertiesToRemove.SetValue("LinearGradientTransparencyB", 1);
PropertiesToRemove.SetValue("LinearGradientColorA", 2);
PropertiesToRemove.SetValue("LinearGradientColorB", 3);
PropertiesToRemove.SetValue("LinearGradientPositions", 4);
PropertiesToRemove.SetValue("TextureImage", 5);
PropertiesToRemove.SetValue("SolidTransparency", 6);
PropertiesToRemove.SetValue("Solid", 7);
break;
case FillTypeEnumerator.Texture:
PropertiesToRemove.SetValue("LinearGradientTransparencyA", 0);
PropertiesToRemove.SetValue("LinearGradientTransparencyB", 1);
PropertiesToRemove.SetValue("LinearGradientColorA", 2);
PropertiesToRemove.SetValue("LinearGradientColorB", 3);
PropertiesToRemove.SetValue("LinearGradientPositions", 4);
PropertiesToRemove.SetValue("PathGradientCenterColorTransparency", 5);
PropertiesToRemove.SetValue("PathGradientCenterColor", 6);
PropertiesToRemove.SetValue("PathGradientSurroundColor", 7);
PropertiesToRemove.SetValue("PathGradientSurroundColorTransparency", 8);
PropertiesToRemove.SetValue("PathGradientFocusDistance", 9);
PropertiesToRemove.SetValue("PathGradientCenterPosition", 10);
PropertiesToRemove.SetValue("SolidTransparency", 11);
PropertiesToRemove.SetValue("Solid", 12);
break;
}
this.Invalidate();
}
}
//SolidFill
int SolidTransparencyValue = 255;
[Category("Color")]
[Editor(typeof(TrackBarEditor), typeof(UITypeEditor))]
public int SolidTransparency
{
get { return SolidTransparencyValue; }
set { SolidTransparencyValue = value; this.Invalidate(); }
}
ColorDialog FillSolidColorDialog = new ColorDialog();
[Browsable(true)]
[Category("Color")]
public Color Solid
{
get { return Color.FromArgb(SolidTransparency, FillSolidColorDialog.Color); }
set { FillSolidColorDialog.Color = value; this.Invalidate(); }
}
}
}
Why for Example I cannot see in property Grid "Solid" Property and I'm be able to see ONLY Shape properties?
What we have to do?IExtenderProvider?
What needs PropertyGrid in System.Reflection for searching also in 2nd,3rd,n class?Service,a CustomDesigner?
Is possible Idictionary is filled ONLY by properties of 1st class? Simply re-populating the "Default Designr PropertyDescriptorCollection I would be able to...seems not...
Please we're in the middle of the Sea..try to Win this challenge!
Thanks to all for Patience!

How do you make a WinForm minimize to the taskbar in the lower-right corner? Also, how can you make it so that the minimize, maximize, and close buttons are disabled on the form?

That's the system tray. There are CP articles on making your app's icon appear in the system tray.

You can remove them entirely in the designer, if you remove just minimise or just maximise, then it will disable instead of being removed.
Oh - sorry. You're not using visual studio for some bizarre reason ( the C# express edition is free ). The form has properties which you can set manually, I believe they are called MinimizeButton, MaximizeButton and the close one refers to the entire menu, I forget it's name.

OK, I've updated my sig.

*** Never give me an answer having anything to do with Visual Studio. I don't have this because I have two computers, one being my dad's mac, which is connected to the internet, the other being my pc, which is, sadly, not connected to the internet. The setup for the Visual C# program I think is called a "bootstrap" program, and it needs to connect to the internet to install the program. THEREFORE I cannot install this program onto my pc.***

OK - now that I understand the problem, you can get the express editions on CD from Microsoft. I recommend it.

How can you associate an icon with a certain type of file, so that when you view the file in Windows Explorer, the file will be displayed using that icon?

That's done in the registry, in the same section that handles what file to use to open a program if you double click on it.
HKEY_CLASSES_ROOT / Word.Document.8 / DefaultIcon
for example.

Hi
I am trying to write a small utility where fill the form and click submit button automatically.
I am using mshtml to get all the information and press the button. But how do i get the button name from code below? Any ideas?
<form method="post" action="/cgi-bin/add_posting.pl"><br />
<fieldset><br />
<br />
<input type="hidden" name="pid" value="0001068190921181587792429822"/><br />
<input type="hidden" name="sms_me" value=""/><br />
<input type="hidden" name="room_type" value=""/><br />
<input type="hidden" name="house_type" value=""/><br />
<br />
<input type="hidden" name="num_bedrooms" value=""/><br />
<input type="hidden" name="contract_type" value=""/><br />
<br />
<button type="submit" class="submit">submit your ad >></button><br />
<br />
<input type="hidden" name="posting_id" value=""/><br />
<input type="hidden" name="current_live_date" value=""/><br />
</fieldset><br />
</form>
Thanks

A regex that looks for a button with type="submit" ? Of course, this button doesn't have a name, unless you mean the text on the button ?

Because this button does not have name. I was not sure how to press it. So i should be using regex ?

OK, so regex isn't going to help you. You're not really asking C# forms questions, you're asking how to interact with a web page, in the browser control, right ? I believe you can just find the submit button(s) using javascript, without needing a name.

You dont really need to click the button, but submit the form.
Give the form some id. Then simple JS document.myForm.submit() should work.

i send 6 arranged datas from outside to c#.net with serialport.and i use serialport_datareceived(..) .i must get these datas in the c# arranged.but i cant get datas with sequence in the c#.how can i solve this problem?my code is this:i mean first data will be
value[1]=first data coming from outside.
value[2]=second data coming from outside
....
i wish i could explain my problem
private void myform_Loaded(object sender, EventArgs e)
{
seriport = new SerialPort();
seriport.DataReceived+=new SerialDataReceivedEventHandler(this.seriport_DataReceived);
seriport.PortName = "COM4";
seriport.DataBits = 8;
seriport.BaudRate = 9600;
seriport.Parity =System.IO.Ports.Parity.None;
seriport.StopBits = System.IO.Ports.StopBits.One;
seriport.ReceivedBytesThreshold =6;
seriport.ReadBufferSize =10000;
seriport.WriteBufferSize =10000;
if (seriport.IsOpen)
seriport.Close();
seriport.Open();
}
private void seriport_DataReceived(objectsender,SerialDataReceivedEventArgse)
{
byte[] values={0,0,0,0,0,0,0,0};
seriport.Read(values, 0, 6);
//icall my functioun here.
}
|
|
|
|
|
Is the data coming into the port delimited? Have you tried using seriport.ReadLine(), then parsing out the line?
|
|
|
|
|
i have 6 datas.and each of data between 0-255 (just one byte).if i use serialport.readline() so how can i separate my datas in visual c#?
for example my datas:
10
245
100
12
250
8
when i use serialport_readline() so how can i seperate these_another question is that will i get datas with arranged?
