Use the tools correctly. It won't work the way you are trying because it would produce an invalid document.
writer.WriteStartElement("Amt");
writer.WriteStartElement("InstdAmt");
writer.WriteAttributeString("Ccv", "EUR");
writer.WriteValue("100.01");
writer.WriteEndElement();
writer.WriteEndElement();

Great!
I obviously tought that you can put WriteAttributeString also after WriteElementString as you can do with WriteStartElement.
This solved my problem, for now 
Thanks for prompt answers.

Hi all, I have two questions .
1. How do I copy one datagridview to another.
2. how do I sort a specefic column. for example I have
col A, colB, colC. I want to sort colB only when data is loaded.
for copying or loading from one grid to another I have done something like this
and it is working but not sure it is a right thing to do or not.
for (int j = 0; j < dataGridView1.Rows.Count; j++)<br />
{<br />
dataGridView2.Rows.Add();
for (int i = 0; i < 5; i++)<br />
{<br />
dataGridView2.Rows[j].Cells[i].Value = dataGridView1.Rows[j].Cells[i].Value;<br />
}<br />
}<br />
thanks in advance

Hi, can someone give any advice on the following problem I have in C# 2...
I have a string such as "this_is_a test|XXmoretexthere". I need a bit of code that if I specify |xx as the sepertor, will return back to me everything after "|xx"
so I have "moretexthere" as a result.
The pattern I pass may vary content and length. The current pattern is held in a string variable. Should the pattern occur more than once in the string, I only need to return everything after the first occurrence.
Whatever solution I use, it needs to be fast as it will run in a loop possibly many thousands of times.
Many thanks for any advice.

A Regular Expression, or IndexOf and Substring.
|
|
|
|
|
it is only an idea you can use find and replace first to change any '|xx' with ';' then use string properties to find the place
!!!!!

|
|

He did say he wanted something fast: Yours involves two searches and two string copies. (Remember strings are immutable, so find and replace will create a new copy of the string, rather than alter the existing one.)
All those who believe in psycho kinesis, raise my hand.

string initialText = "this_is_a test|XXmoretexthere";
string searchString = "|XX";
int lastIndexFound = initialText.LastIndexOf(searchString);
if (lastIndexFound > 0)
{
MessageBox.Show(initialText.Substring(lastIndexFound + searchString.Length));
}
else
{
MessageBox.Show("Patternt not found");
}
Not sure if this is fast enough...Not sure if the search is case sensitive otherwise....

Hi folks, thanks for the replies.
Regarding a RegEX, can someone supply an example of the correct syntax for my requirements. I've tried Googling this but I just get confused by it's syntax.
Thanks.

|

|

Use this
string[] str1 =str.Split(new string[] { "|xx" }, 2,StringSplitOptions.None);
The second value that is str1[1] will have the value you are looking for.
Do let me know if this is not the one you were looking for..

Thanks Jack, that also worked and never occurred to me. Would it be quicker than the LastIndexOf method though?

I'm creating a security application that is using WinForms it reads in am image from an XML and displays that image in a Thumbnail format. Then when the image is double click it is populated in a second window with icon image representing specific security devices. In the second window I need to be able to zoom and pan the image along with the icon displayed over top the image.. Right now when I go to zoom the main image is the only thing that zooms but it doesn't not pan. I need to be able to make the icons zoom with the image and make the whole thing pan accordingly. Any help with this would be great. Keep in mind that the main map image I can zoom and pan my problem is when I move the mouse off the scroll bar the image doesn't stay where I panned it to.
Additional Note: Not sure how much information you will need to help so I attached the code from both Forms in the zip file along with the XML code below that stores the information about the images and the icons. Please let me know what other information you might need to assist me.

Hey guys sorry for disturbing again....
now a new and intressting problem:
I have installed now Office XP && Office 2007. If I create a new excelfile with
worksheet.SaveAs(txtSavePfad.Text, t, t, t, t, t, t, t, t, t);
it become a ".xls"
Previous I only had Office 2007 and the same code created a ".xlsx" file then I used the following code to create a ".xls":
worksheet.SaveAs(txtSavePfad.Text, XlFileFormat.xlExcel8, t, t, t, t, t, t, t, t);
I've a string with the full path, it contains which format I want to use... ("a\b\c\2003.xls" or "a\b\c\2007.xlsx")
if (txtSavePfad.Text.Substring(txtSavePfad.Text.LastIndexOf(".")) == ".xls")
worksheet.SaveAs(txtSavePfad.Text, XlFileFormat.xlExcel8, t, t, t, t, t, t, t, t);
else if (txtSavePfad.Text.Substring(txtSavePfad.Text.LastIndexOf(".")) == ".xlsx")
worksheet.SaveAs(txtSavePfad.Text, t, t, t, t, t, t, t, t, t);
excelApp.Quit();
so what could I do to save the file in the right form? 
greets Mschauder

It sounds like you have installed stuff in the wrong order. Check out this MSDN article[^]
If stuff is installed in the wrong order it won't work properly.
My personal experience is that although Microsoft claim you can (but not recommended) have both versions installed at the same time, in practice every piece of code you write is almost guaranteed to break.

Iam exploring for samples on G-mail from last 2 days . I ended up with no samples in Place. Can any body please share the samples list or any links to explore. I want to retrieve all the mails from G-mails and organize it into my application... Thanks.

You can enable POP3 on your gmail, and use POP3 for the mailbox access. I think there are a lot of samples about POP3

Thread th = new Thread(delegate()
{
e.Graphics.DrawEllipse(new Pen(Brushes.Aqua, 10), new Rectangle(20, 20, 20, 20)); //this line throw new exception "Invalid argument"
});
th.Start();
help pls

First you are not passing the eventargs variable e into the delegate function.
Secondly, you cannot perform GUI operations from any thread except for the one on which the form was created.
|
|
|
|
|
form1.CreateGraphics() and this is workling in other thread
|
|
|
|
|
Just because you can do it doesn't mean it's a good idea. You're still going to run into issues somewhere down the line. You absolutely cannot do any drawing to the controls on a thread other than the one the control was created on.

Hi!
I have a dataset colum wich values ara simple integers.
I want to create a ComboBox with some string values, and databind the dataset as an INDEX to them.
So,
dataset has 1,2,3,4
my Combobox has "myString1", "myString2" (I can popolate manually or progrmatically, but theese values are NOT provided by the dataset)
I want to databind my dataset to my combobox so that when dataset value is 2, the combobox show "myString2".
I think it should be easy... but i'm not too used to combobox neither databind
Thanks!
|
|
|
|

If you set the datasource for a combobox then the datasource must contain both the ValueMember and the DisplayMember otherwise it will not work.
in order to databind the ValueMember must point to a corresponding value in the datasource
eg.
Your datasource for the combobox would be a datatable such as:
ID VALUE
=============
1 myString1
2 myString2
Your dataset would have a column in the table (MyTable) containing the idStrings value for example.
MyCombo.DataSource = source;
MyCombo.ValueMember = "ID";
MyCombo.DisplayMember = "VALUE"
MyCombo.DataBindings.Add("SelectedValue", MyData, "idStrings")
