Try this
System.Xml.XmlNode node;
System.Xml.XmlDocument doc = new XmlDocument();
doc.LoadXml("<person><name>jon</name><age>35</age><zip>47408</zip></person>");
this.textBox1.Text=doc.InnerXml;
node = doc.SelectSingleNode("person");
node.RemoveChild( doc.SelectSingleNode("person//zip"));
textBox1.Text += "\n" + doc.InnerXml;

Hello, I'm trying to grab the entire bitmap for a Windows Form when performing a drag/drop operation, using the code below.
This works fine, except for when part of the form is off-screen or hidden by, say, another window -- in this case the bitmap returned includes part of another window / the Windows Taskbar or whatever is there.
Does anyone know of a way to get the entire bitmap for a Window (i.e. the image that would be shown by that window if it was completely on-screen, topmost and visible). Is there perhaps a native API that can help with this?
Any ideas would be much appreciated, as I'm beginning to think this can't be done.
Andy
[DllImport("gdi32.dll")]
public static extern bool BitBlt(IntPtr hdcDst, int xDst, int yDst, int cx, int cy, IntPtr hdcSrc, int xSrc, int ySrc, uint ulRop);
public Image GetBGImage(System.Windows.Forms.Form formToCopy)
{
Graphics g = Graphics.FromHwnd(formToCopy.Handle);
Bitmap bm = new Bitmap(formToCopy.ClientRectangle.Width, formToCopy.ClientRectangle.Height, g);
Graphics g2 = Graphics.FromImage(bm);
IntPtr hdcScreen = g.GetHdc();
IntPtr hdcBitmap = g2.GetHdc();
BitBlt(hdcBitmap, 0, 0, bm.Width, bm.Height, hdcScreen, 0, 0, 0x00CC0020);
g2.ReleaseHdc(hdcBitmap);
g.ReleaseHdc(hdcScreen);
return bm;
}

Hello,
Is there a way of formating the number string is such a way, if an input string is:
450000 for example.
How can I make the output string to be something like that:
450,000.
Sort of putting commas for each of the hundreds
Thank you
|

I just tested this... you can do the following....
<br />
string buff;<br />
int test = 450000;<br />
buff = test.ToString("###,###");<br />
test = 450000000;<br />
buff = test.ToString("###,###");<br />
And the commas are put in the right places for both tests.

Do you have a string or a number? If you have a number, it's easy. Numeric format with zero decimals:
string result = myNumber.ToString("n0");
You can also create a NumberFormatInfo object, where you can specify any format you like:
NumberFormatInfo info = new NumberFormatInfo();<br />
info.NumberGroupSizes = new int[] {1, 2, 1, 0};<br />
info.NumberGroupSeparator = "-beep-";<br />
string result = myNumber.ToString("n0", info);
Edit:
If you have any problems with the first example because of locale settings, use an invariant format info:
string result = myNumber.ToString("n0", NumberFormatInfo.InvariantInfo);

To get additional page to be printed
Set PrintPageEventArgs.HasMorePages to true
private void printDocument1_PrintPage(object sender,System.Drawing.Printing.PrintPageEventArgs e)
{
if(your condition)
e.HasMorePages = false;
else
{
e.HasMorePages = true;
}
}
look at
PrintPageEventArgs.HasMorePages [^]

My dad is trying to teach me C# . NET and i stumbled onto a problem while trying to create my own program. I would like to know how to take the numbers of one text box, multiply them by 2 and project them onto another textbox. Keep in mind though that im a begginer and dont understand hard code. Thanks for your help
|
|
|
|
|
What you have to do is to convert the string that you get from the text box into a number. Then you can do the math, and finaly convert it back to a string and put it in a text box.
AnotherTextbox.Text = (Convert.ToInt32(OneTextbox.Text) * 2).ToString();
Step by step:
string inputValue = OneTextBox.Text;<br />
int numericValue = Convert.ToInt32(inputValue);<br />
int calculatedValue = numericValue * 2;<br />
string convertedValue = calculatedValue.ToString();<br />
AnotherTextBox.Text = convertedValue;

Hi,
I Have a Problem and I Want anyone help me,
I Have Five Forms. The Fifeth one Contain Tab Control, This Tab Control Contain Four Pages And I Want By Object-Oriented Put The Four Forms In The Four Pages Of The Fifth Form.

Hi!
Convert your four Forms into four UserControls and for each TabPage set one of these UserControls as the only child with DockingStyle.Fill so that it occupies the whole TabPage.

If your Application Type is MDI you can iterate through
Them By write somthing like
foreach(Form form in this.MdiChildren)
{
}

Hello, i have a MDI application with several child windows, my problem is that i wont the user to be able to open only one instance of each window, but to have all different windows open at same time (or the amount he choses). How do i do this? With active MDI child property i can only acess the active window, and thus the user always can open a new instance of a not active window. Please advice me, i would apriciate some code examles.
R

You can loop through childs forms
foreach(Form form in this.MdiChildren)
{
}
Or you can Use Hashtable and store each opend form in it
And chech it before open new form

I have written a sql class with generic select insert and update functions. The problem I'm having is I have to update aprox 500,000 items a day and when I do this sql servers memory usage goes up over 1Gig compared to less than 1Meg during normal operation and is never reset unless sql server is stoped and restarted. The other problem I have is it takes 7-8 hours to update this many items. The following is the update function of the sql class. There used to be 2 databases thats why the if(_DBName.Equals("eBay")) statment is there. I am importing from a delimited file.
public int UpdateTable(string _DBName, string _table, string _columnandvalues, string _where, bool _returnscope)
{
int itemid = -1;
if(_DBName.Equals("eBay"))
{
if(m_CompanysqlADONetConnection.State == System.Data.ConnectionState.Closed)
{ m_CompanysqlADONetConnection.Open();
}
SqlCommand mySqlCommand = m_CompanysqlADONetConnection.CreateCommand();
mySqlCommand.CommandText = "Update "+_table+" Set "+_columnandvalues+_where+" SELECT SCOPE_IDENTITY()";
if(_returnscope)
{
object obj = mySqlCommand.ExecuteScalar();
itemid = Convert.ToInt32(obj);
}
else
{
mySqlCommand.ExecuteNonQuery();
}
mySqlCommand.Dispose();
return itemid;
}
else
{
if(m_CompanysqlADONetConnection.State == System.Data.ConnectionState.Closed)
{
m_CompanysqlADONetConnection.Open();
}
SqlCommand mySqlCommand = m_CompanysqlADONetConnection.CreateCommand();
mySqlCommand.CommandText = "Update "+_table+" Set "+_columnandvalues+" "+_where+" SELECT SCOPE_IDENTITY()";
if(_returnscope)
{
object obj = mySqlCommand.ExecuteScalar();
itemid = Convert.ToInt32(obj);
}
else
{
mySqlCommand.ExecuteNonQuery();
}
mySqlCommand.Dispose();
return itemid;
}

Hello,
How can I itterate through a collection of tabs, using foreach statement?
Thank you.
|
|
|
|
|
Hi, it's really simple.
Let's say you have a tab control called myTabControl.
<br />
TabControl myTabControl = new TabControl();<br />
<br />
<br />
<br />
foreach (TabPage Page in myTabControl.TabPages)<br />
{<br />
<br />
}<br />
TabPages is the collection you're looking to iterate through.

Thank you. That is exactly what I am looking for.

create these two tables in a xml file and read it to a dataset. create a relation ship for item code column. Now I have to add two datagrids in the program.Add data biniding for both the grids.
Andshould bind one grid to parent table and bind one grid to child table. using dataviewmanager I have to do this. Now implement the binding context
And add a button to your form in the click event of that button increase the binding context by 1.
then u will see that according to parents table's code in the grid it will show only that items i n the child table grid..
This is my requirement.
I have created 2 xml files with the data and added 2 datgrids.
Private DataSet ds= new DataSet()
Private void fngetconnected()
{
DataSet xml1 = new DataSet();
xml1.ReadXml("C:\\relation\\parentable.xml");
DataTable dt1 = xml1.Tables["parenttable"].Copy();
DataSet xml2 = new DataSet();
xml2.ReadXml("C:\\relation\\childtable.xml");
DataTable dt2 = xml2.Tables["childtable"].Copy();
ds.Tables.Add(dt1);
ds.Tables.Add(dt2);
DataColumn parentCol = ds.Tables["parenttable"].Columns["code"];
DataColumn childCol = ds.Tables["childtable"].Columns["code"];
DataRelation relTable1Table2;
relTable1Table2 = new DataRelation("parentchild", parentCol, childCol);
ds.Relations.Add(relTable1Table2);
//Create Dataview setting for each table
//using DataView Manager
DataViewManager myDVM = new DataViewManager(ds);
myDVM.DataViewSettings["parenttable"].Sort = "code DESC";
myDVM.DataViewSettings["childtable"].Sort = "code Desc";
dataGrid1.SetDataBinding(myDVM, "parenttable");
dataGrid2.SetDataBinding(myDVM, "childtable");
}
I have added 2 datagrids and vreated a relation and set databinding to two grids such that one grid shows parenttable and another shows childtable.
Now I have to add a button and when clicked, I have to see that according to parents table's code in the grid it will show only that items i n the child table grid..using binding context.
How to do this.Pls anyone help to do this.
