Hello,
I currently have a form that reads through an xml file and displays information based on the object selected in the combobox.
I can read the information from the xml just fine, but editing and saving the information is where I'm having trouble at.
xml file:
<Objects>
<Object name="Square">
<Height>15</Height>
<Width>15</Width>
<Color>red</Color>
<Object name="Circle">
<Radius>10</Radius>
<Hollow>True</Hollow>
<HollowRadius>5</HollowRadius>
<Color>blue</Color>
</Objects>
How would I change the "Sqaure" objects height value?
or
How would I change the "Circle" objects hollow value to false?
Thanks

<br />
using System.Xml;<br />
<br />
public void ChangeObjectHeight(string Name, int Height)<br />
{<br />
XmlDocument Doc = new XmlDocument();<br />
Doc.Load("yourfilenamehere.xml");<br />
<br />
XmlNode Node = Doc.SelectSingleNode("/Objects/Object[@name='" + Name + "']");<br />
XmlNode Node2 = Node.SelectSingleNode("Height");<br />
Node2.InnerText = Height;<br />
<br />
Doc.Save("someplacetosavetheshit.xml");<br />
}<br />
or something to that extent.

Thanks very much, you rock!

Really? String concatenation? And multiple queries? That's how it's done? 
string xpath = string.Format("/Objects/Object[@name='{0}']/Height", Name);<br />
Doc.SelectSingleNode(xpath).InnerText = Height.ToString();

How?
Also your XML is not valid so until you fix that it will be difficult to help you.

Hello all.
Now that I have discovered extension methods, I am revisiting my libraries of handy-dandy routines to see where it makes sense to convert them. In doing so I am also revisiting a question about how to handle methods that work on different data types.
I am wondering if anyone out there has any opinions or knows any arguments for/against writing such methods in a particular style. I know there probably isn't any one "right" answer, but I thought it would be informative to hear what other programmers think.
For instance, I have a lot of methods that work on strings. I also need the same operations to work on character arrays. So I might end up with something like
public int foo ( char[] SourceData ) { ... }
public int foo ( string SourceData ) { ... }
I have also handled this using
public int foo ( char[] SourceData ) { return foo(new string(SourceData)); }
public int foo ( string SourceData ) { ... }
and even
public int foo ( object SourceData )
{
string source;
if ( SourceData.GetType() == typeof(string) ) source = SourceData;
else if ( SourceData.GetType() == typeof(char[]) ) source = new string(SourceData);
else error_condition;
...
}
I started to look at generics, but it seems that they may be a bit of overkill for routines that only handle 2 or 3 different data types.
Opinions? Critisisms? Other ideas? All are welcome.

Why would generics be overkill. Just because you are limiting to only 2 or 3 data types, generics are still very useful. Let's face it, generics (in most cases) are often only used against a couple of types only. Don't limit yourself just because your code doesn't use every possible type.

 Smooth. You've definitely mastered the one liner.

Thanks Pete. I will take a look a closer look at generics.
I'm not quite sure what led mike meant by "He may not be", though.

I'm trying to figure out a way to set a tooltip for each individual ColumnHeader on a ListView. Unfortunately, ListView can't extend ColumnHeader by default, at least that's what ToolTip.CanExtend(object) reports when I try to run it on an instance of ColumnHeader.
I was wondering if anyone could point me in the right direction for this. After doing a Google search I found a few message board postings where WndProc was overloaded on the ListView control butall were too vague or used types they didn't define.
I know column headers in DataGridView are able to handle ToolTips so I'm going to take a look at that via reflector. Hopefully, that'll shed some light on what I need to do.

Hi All,
I want to display the sum of the values of a field on my report.
im using 'Running total fields' , then i select the field, bud i don't see the 'Sum' selection on the 'Type of summery' combobox...anyone any idea???
Thanx.

Try adding a formula field and setting its value to the sum of the field you're looking for.
So the formula text would be something like:
Sum ({Table.Fieldname})
The Sum function also allows you to set specific criteria on what to count. I'm not sure how flexible it is, but it's there.

Read the first message in the forum titled "How to get an answer to your question", pay attention to item #2
Then after you have done that, go to the articles on this site and you will find a series on C# Image Processing. You will find the articles under the "Chapters" menu item.

Obviously you're too stupid and lazy to handle the task. Try doing something you can handle, like sweeping streets or selling fruits.
No one is going to guide you through any process or give you C# code.

Extracting the content between the opening and closing elements of a HTML tag is a pretty common problem.
Have you made any attempt to solve the problem yourself, i.e. by searching the web?
If not, I suggest you do so. People who can't do basic research generally don't receive help in this forum.

Thanks for the suggestion.
I wish I didn't do research on the net so that I can deserved what you've said.
Anyways, I think I better get help from others rather than from those who help nothing.

I only help those that help themselves.
As you don't seem to be interested in solving the problem yourself and expect the solution handed to you on a place, you'll get no further help from me.

Frankly, i did spend half an hour solving it already before I posted for help. Just right 10mns after posting this, I figured out the solution.
You have to understand that not everyone is like what you've thought that when they face problem they just jump up straight to the forum for help!! They might have tried their best already before coming to the forum.
You might have thought that you are a great forum answerer, but without good attitude and respectful to others, you deserve nothing from us.

I don't want anything from you. I already know how to solve problems like yours. To be quite frank, judging by your skill level I doubt there's anything useful you could teach me.
I'm happy to help people who have demonstrated they're made a serious attempt to solve the problem they are asking for help with. I saw no evidence of this in your posts. If you want respect, first you have to deserve it.
