Regular expression [modified]

Hey guys, I'm trying to create a regular expression which matches text with html links in it. I want to extract both the URL and the 'clickable' text. The regular expression so far :

(<a(.)*href=("|')(?<url>(.)*)("|')(.)*>(?<text>(.)+)</a>)

Now in general, this works. When I enter a text with a html link in it :
blah blah blah <a href="/link.aspx" target="_blank">clickable text</a> blah blah

The regular expression returns one match containing <a href... ... </a> so that works fine...
However, when I enter a text that contains two links :
blah blah blah <a href="/link.aspx" target="_blank">clickable text</a> blah blah blah blah blah <a href="/link.aspx" target="_blank">clickable text</a> blah blah

The regular expression still returns one match, containing the first <a href... till the second </a> which is not the wanted result. I want the regular expression to return two matches. Can anyone help me?

Regex regx = new Regex("<a(.)*href=(\"|')(?<url>(.)*)(\"|')(.)*>(?<text>(.)+)</a>", RegexOptions.IgnoreCase | RegexOptions.Multiline | RegexOptions.Compiled);
MatchCollection col = regx.Matches(Input);

Try this tool, Expresso[^]. It has a library of regex and testing environment that may help

I am familiar with Expresso, which by the way returns the same result. Expresso also returns only one match containing the tag opening of the first link, untill the closure of the second link. I want two matches with both links Wink | ;)

Thanks for the help anyway

I think your problem is that . is greedy. You should make it lazy with ?. (Reference[^])
This <a(.)*?href=(\"|')(?<url>(.)*?)(\"|')(.)*?>(?<text>(.)+?)</a> should work. Although it is untested.
Lazy lookup is less efficient than regular lookup so you may want to use something more appropriate like (?<url>[^'"]*).
I have found http://www.regular-expressions.info/[^] to be a great resource.

[SOLVED] How do I get the type of the class I'm in without knowing its name? [modified]

Hi everyone.

I'm creating a class through reflection and I'd like to have a static initializer like this:

class MyClass {
     static MyClass() {
          someMethod(typeof(MyClass));
     }
}

That is, I'd like to obtain the type of MyClass and pass it to someMethod as argument. What's giving me trouble is obtaining the type of MyClass, since I'm emitting this code before the type MyClass is created: I'm defining MyClass with a TypeBuilder, but I haven't called CreateType() yet because I first need to add the static initializer. I have a hen-and-egg situation here.

Ideally what I'd like is to do something like:

class MyClass {
     static MyClass() {
          someMethod(this.GetType());
     }
}

but of course not with this because I'm in a static member and there's no "this". So, is there something equivalent to this but that identifies the class (or type) in which the code is declared (i.e., to which class belongs the code that is being run)? Sorry if I don't make much sense, I'm having trouble expressing this clearly Blush | :O

Thanks!

No, sorry, the problem is I'm emitting the code with Reflection.Emit, so I can't just type "MyClass".
It works like this:
* Someone calls my class ObjectFactory with a Type they want me to extend, say "MyType".
* Using reflection, I create a subclass of MyType, called EXT_MyType, which has some extra fields and methods. I want to add a static initializer to EXT_MyType, which should look like this:

static EXT_MyType() {
    someMethod(typeof(EXT_MyType));
}

But the problem is when I emit the code for this static initializer I haven't yet created the type EXT_MyType (that's what I'm doing, I'm creating its static initializer, etc), so I don't know how to emit this code. See, I'm trying to emit it like this:

ilGenerator.Emit(OpCodes.Ldtoken, typeof(EXT_MyType));
ilGenerator.Emit(OpCodes.Call, typeof(EXT_MyType).GetMethod("someMethod"));

but EXT_MyType doesn't exist yet. So I'm wondering whether there's a primitive or something I can invoke from within the static initializer that will allow me to do this instead:

static EXT_MyType() {
    someMethod(getTypeOfThisClass());
}

Where getTypeOfThisClass() would be that "primitive or something...". Since this call would take place once I've created EXT_MyType there wouldn't be a problem. I just don't know whether a primitive like that exists.

If it doesn't, I'd appreciate suggestions on alternative ways of doing this.
Thanks!

There's no such primitive. You'll have to emit a typeof(EXT_MyType).
This doesn't mean that typeof(EXT_MyType) has to appear in your code - you can get the System.Type instance in other ways using the Reflection API.
In fact, I think you already are using that System.Type instance: System.Reflection.Emit.TypeBuilder derives from System.Type.

So you should be able to use:

ilGenerator.Emit(OpCodes.Ldtoken, myTypeBuilder);

19-Feb-10 2:35

Yeah, thanks, I think that's it. I had actually found a solution:

ilGenerator.Emit(OpCodes.Ldtoken, classInitializer.DeclaringType);

but of course yours is better, since there's no point doing it like that when I already have the type builder. It was a newbie question Poke tongue | ;-P

Thanks!

(I was going to post my own solution but I'm still having some (hopefully unrelated) issues, so I was waiting to see if it really did solve the problem; I'll mark the thread as solved, though)

..or you create a small method that gives you an new and open connection;

SqlConnection GimmeConnection()
{
    SqlConnection con = new SqlConnection(connectionString);
    con.Open;

Get an "index" for a field of a class?

blackblizzard18-Feb-10 23:29

blackblizzard

18-Feb-10 23:29

Hi everyone.
I'm having trouble with the following: I need a way to distinguish the different fields of a class by means of integers -- for example, given the following class:

class MyClass {<br />
<br />
float floatField;<br />
double[] arrayField;<br />
Object objectField;<br />
<br />
}

I'd like to be able to identify floatField as field 0, arrayField as field 1, and objectField as field 2. I don't really care about the order, but I need the integers to be consecutive and to never change throughout execution. They can change between executions.

I haven't seen any straightforward method for this in Type. The best I can come up with is to call typeof(MyClass).GetFields() and use the order the fields in the return array as their id. For example, if it returns [floatField, arrayField, objectField], it would return in the ids I mentioned above (0, 1 and 2, respectively).

I'm going to need to find the id of a given field pretty often throughout execution, so I create a dictionary that maps the name of a field to its index, like so:

int i = 0;
Dictionary<string, int> fieldOffsetDict = new Dictionary<string, int>();
foreach (FieldInfo field in typeof(MyClass).GetFields(BindingFlags.Instance | BindingFlags.Static | BindingFlags.NonPublic | BindingFlags.Public)) {
    fieldOffsetDict[field.Name] = i++;
}

Anyone can think of a better way of doing this (for example, is there a method that I've failed to see that would do this directly), or do I keep it as it is? I can't help but feel this is a bit of an overkill, so I'd like to make sure.

Also, if I didn't mind the ids not being consecutive, would there be a better way to do this?

Thanks.

Hi,

if you want a free choice for the field names, and need name->ID mapping, the dictionary seems best; for a simple ID->name mapping, a List would suffice.

if you don't really care about field names, then why not name them consecutively, hence:

class MyClass {
    float f0;
    double[] f1;
    Object f2;
}

I only read code that is properly formatted, adding PRE tags is the easiest way to obtain that.

Memory Leak in WPF. Multiple instances of the same control in memory. [modified]

Hello!
I have a problem with some WPF controls.

For example I created a derived from Window tooltip, that will display the .xaml instance of MenuButtons. MenuButtons just simply containts 2 buttons that can be clicked by the user. That's the code :
(menuContentTooltip is a class derived from Window, and that will contain my WPF .xaml MenuButtons control, this menuContentTooltip is a global variable)

if (menuContentTooltip != null)
            {
                menuContentTooltip.Close();
                menuContentTooltip = null;
            }

            MenuButtons menuButtons = new MenuButtons();

            var ttp = new ToolTipParams
            {
                ParentFrameworkEl = menuBtn,
                ChildControlInToolTip = menuButtons,
                Title = "Menu",
                PositionOfToolTip = ToolTipParams.Position.Below
            };
            //------------------------------------------
            menuContentTooltip = new ToolTip(ttp, false, null);
            if (menuContentTooltip.ChildControl != null)
            {
 ((MenuButtons) menuContentTooltip.ChildControl).DemmarerButton.MouseLeftButtonUp += delegate
{                                                                                                             /*Do some work here*/
                                                                                                             if (menuContentTooltip != null)
                                                                                                                 menuContentTooltip.Close();
                                                                                                         };
 ((MenuButtons) menuContentTooltip.ChildControl).GestionButton.MouseLeftButtonUp += delegate
                                                                                                           {
     /*Do some work here*/                                                                                                          if (menuContentTooltip != null)
                                                                                                                   menuContentTooltip.Close();
                                                                                                           };
                menuContentTooltip.ShowToolTipIfNotAuto();
            }

The problem is that everytime when I click the button that executes the code above, the application memory increases without reason, and if I do memory dumping, loading SOS.dll, I see more and more objects of MenuButtons type. For example I clicked and closed the tooltip 3 times, then in visual studio I see this:

!dumpheap -mt 036424f0

This is C# forum. Here on codeproject there is also forum for WPF
As i know about C# and windows form, the only whay to get memory leak is not to dispose unmanaged resources. Image class is such thing. And it would help if you use <pre></pre> tags around code, so that we can see it nicly formated

DatagridViewColumn displayIndex - column order wrong after setting them from control settings table.

Hi,

I have a datagridview upon which I allow the user to re-order the columns. I then store the column order in a sqlServer database table. When the user starts the datagridview my code reads the database and retreives the user's column positions.

The code loops through the columns and sets the displayIndex as previously saved. No problems except the columns are displayed in the wrong order Confused | :confused:

The effect is rather inconsistent and not all the columns are in the wrong order.

Under the debugger I can see the displayindices are correctly set as per the database table. The columns just appear in the wrong place on-screen Unsure | :~

I have a fix Smile | :)

I simply run the code that sets the displayIndices twice. The problem goes away (well up to now).

I wonder if anyone has had similar displayIndex problems and has a better fix? I have one or two comments in my code saying //DONT REMOVE THIS CODE. IT LOOKS WRONG BUT IS FIXING AN ISSUE.

Hi,
I happend to have exactly the same strange problem! Unfortunately I have no better solution.
Has anyone else figured this one out or is it a DataGrid bug?

Suppose your DataGridView has the columns A, B, C, but they should be displayed as B, A, C.
The desired column order will be restored from this table:

Column name  Index  DisplayIndex
A            0      1
B            1      0
C            2      2

Before you loop thru this table sort it by DisplayIndex:

Column name  Index  DisplayIndex
B            1      0
A            0      1
C            2      2

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
