check encoding and update it accordingly.
Cheers!!

Make sure the encoding is the same. You should probably use UTF-8
ASCII tables, HTML entities, types, string formats and more info for the serious coder at: www.codecharts.com

Ok, three people so far have suggested that it's the encoding that is the problem.
Anyone else why want to suggest that it's the encoding that is the problem before we close?

Not me.
I'm thinking there's characters in the stream that are invalid for the encoding of the XML.

hi evreyone
is it possible to use xml file as database ?
if yes, is someone has any sample code in C# that can do Insert,Update and Delete job's ?
thank's alot for any help
|
|

Yes you can. But it doesnt mean you should. Performance wise its even a worse idea.
To do insert/update/delete you will need to load the xml document, find the node that you want as parent (for insert) or the node you want to update/delete, perform the action you need to do and then save the document again.
Loading the document once and keeping it in memory will speed up the process if its small amounts of data, else you'll find yourself running out of memory soon.
Hope this helps.

thank's for the quick anser
by database is very very small and i think,
that it will be better to use xml insted access or sql server
can i get any sample ?

As Guffa has said, its easy to load the data in a datatable and then save it as xml. That will increase query performance. That will however increase your xml document size.
If you dont want to use that way, heres a really simplified example of an update to a xml file:
<?xml version="1.0"?>
<Employees>
<Employee>
<ID>1</ID>
<FirstName>John</FirstName>
<LastName>Doe</LastName>
</Employee>
<Employee>
<ID>2</ID>
<FirstName>Peter</FirstName>
<LastName>Pan</LastName>
</Employee>
</Employees>
string xmlFilePath = @"C:\Employees.xml";
int EmployeeIdToUpdate = 2;
string NewEmployeeLastName = "Panne";
System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
doc.Load(xmlFilePath);
System.Xml.XmlNode eNode = doc.SelectSingleNode("Employees");
for (int i = 0; i < eNode.ChildNodes.Count; i++)
{
System.Xml.XmlNode employeeNode = eNode.ChildNodes[i];
int ID = int.Parse(employeeNode.SelectSingleNode("ID").InnerText);
if (ID == EmployeeIdToUpdate)
{
//Perform action
employeeNode.SelectSingleNode("LastName").InnerText = NewEmployeeLastName;
}
}
doc.Save(xmlFilePath);
Hope this helps.

You can save and load a DataTable as xml. Load the DataTable, change the DataRow items, and then save it.

good.....
can i get code sample ?
|
|
|
|
|

.NET has many XML manipulation classes available. Use any of them to load and save data to XML file. If you are looking for file system based database, consider SQL lite[^]

Just use a borderless form.
xacc.ide - now with TabsToSpaces support IronScheme - 1.0 beta 1 - coming soon ((lambda (x) `((lambda (x) ,x) ',x)) '`((lambda (x) ,x) ',x))

|
|
|

OK... but how do i find out, WHERE the Window should have its location?
And... "close" the form... how works that? Because, if it's a DialogForm i can't close it by clicking somewhere else!

I have a problem when I want call funtion in gridview by using templatefield.
The scenario is like this :
I want to call function : % of Compliance = getComplaince(field1,field2) in gridview. For your information field1 and field2 to in this gridview was set visible=false.
For example field1 = 1, field2 =1
The code is like below :
Field 1 Field 2 Application Definition % of Compliance
1 1 SMP Sistem Maklumbalas getCompliance(1,1)
2 1 E-App E-Application getComplaince(2,1)
getCompliance Function
1 public string getCompliance(int applicationID, int serviceID)
2 {
3 serviceCalculation c = new serviceCalculation();
4 string itemAB = c.getItemAB(serviceID, applicationID, lblError);
5 string[] splitItem = itemAB.Split(',');
6 string comply = c.countCompliant(splitItem[0].ToString(), splitItem[1].ToString());
7 return comply + "%";
8 }
getItemAB Function
1 public string getItemAB(int service, int applicationID, Label lblError)

Hi
I am trying to set two different background images to two different resolution monitors.
I know that i can use somthing like
<br />
const int SPI_SETDESKWALLPAPER = 20 ;<br />
const int SPIF_UPDATEINIFILE = 0x01;<br />
const int SPIF_SENDWININICHANGE = 0x02;<br />
<br />
[DllImport("user32.dll", CharSet=CharSet.Auto)]<br />
static extern int SystemParametersInfo (int uAction , int uParam , string lpvParam , int fuWinIni) ;<br />
<br />
<br />
and so on to get and set the wallpaper for a single monitor, but i am not sure how to expand this to work with 2 or more monitors.
I have had a look at the Screens.AllScreens class, but that seems more about the resolution and so on.
Anyone have any thoughts on how to do this?

Does windows even support this ??

I think theres a program called ultramon that can do it, and my nvidia graphics driver software can assign a diffferent image to each monitor.
Im very sure its possible.

yeah. Makes sense that is is driver-dependent. I cant do it on my Matrox G550.

I have been working on a notepad program that has sorting functions, I am having problems sorting large files, I have been getting outofmemoryexceptions, my test machines have had overkill amounts of memory, so that's not the issue. I have made sure to null and dispose my variables and objects, using "USING" code blocks as frequently as possible. I can't seem to solve this problem. I believe that an external sorting algorithm would be the only possible solution. But I can't find anything on it. I have read an outline of a the idea. but I just can't figure out how to implement one. I have scoured google, yahoo, ask, and dogpile for hours. there just doesn't seem to be any examples of a external merge sort anywhere. There is plenty of proof it exists, collage syllabuses with external merge sort in title, a wikki page describing its usage, I just can't find any C# help about.
if anyone could help me with an example, or a code snippet, or just a more in depth explanation that i might grow on.
I am at a loss,
Thanks,
DiamondDrake

External sorting is just a term to mean a sort algorithm that can sort a large load of data without requiring it to all be loaded into memory at the same time.
The simplest example is the external merge sort. You just divide the data into equal sized blocks that you can handle. Sort each block and write it back to disk. Then load the first few values of each block into input buffers, and merge them into an output buffer. When the output buffer fills, write it to disk and clear it. If an input buffer empties, load some extra values from it's associated block.
This wikipedia article has a step by step process, and a few useful links. http://en.wikipedia.org/wiki/External_sort[^]
Before you consider this though, make sure you really need it. If you are sorting hundreds and hundreds of megabytes of data, then yes you need to do something like this. How big is the data file you are sorting? If it can sensibly be held in ram in one go, then you probably don't need to do external sorting.
