The problem has to lie in the GetEnumerations method - though I can't imagine what could be in it that would cause the behaviour you're experiencing!

I'd put beakpoints all over that method to find out what's going on.

See, that's the thing. I've already done that. Its not even accessing the method. It just reverts back to the MDI form's code. It just exits the Child's load event handler. The form displays fine and function alright (I checked other stuff in the form and it works perfectly fine).

Its driving me insane.

And I'm really sorry for the late reply but the electricity was out for a few hours.

Are you absolutely sure that the handler is being called at all?
Maybe you (or the designer) have deleted the line that adds the handler method to the delegate's invocation list, or a different method is in there?

OK. I went a few levels back and caught the very basic exception being thrown (it turns out that there is an exception being thrown!)

I'm getting a:

{System.TypeLoadException: Could not load type 'RCH.BL.Inventory.ItemCategory' from assembly 'BL, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.
   at RCH.Inventory.Forms.frmAddItem.GetEnumerations()
   at RCH.Inventory.Forms.frmAddItem.frmAddItem_Load(Object sender, EventArgs e) in C:\Data\Work\Asclepius\trunk\src\Inventory\Forms\frmAddItem.cs:line 115}

Now why would this happen?

Thanks to JSOP for the tip! I'm posting this to him as well

Add a try/catch block around the call to GetEnumerations.

How to find multiple occurrence in a string.

Hi all,

I want to find multiple occurrence of a string.

I used string.Contains() method and it returns only the first occurrence. I want to find how many occurrence and add some characters in that index. How can I do that?

Thanks Smile | :)

I appreciate your help all the time...

Contains() internally calls IndexOf() method...For finding the multiple occurrences use IndexOf() and loop through the entire string.

Try this:

string text = "one two three one oneone, someone for";
string wordToFind = "one";
int wordCount = 0;
int pos = 0;
while (pos >= 0)
{
	pos = text.IndexOf(wordToFind);
	if (pos >= 0)
	{
		wordCount++;
		text = text.Substring(pos + wordToFind.Length);
	}
}

The example above should result in a wordCount of 5.

Here's a variation of the answer I gave previously. In this example, I supply code to count instances of the exact word.

string text = "one two three one oneone, someone for";
string alphaNumbers = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
string wordToFind = "one";
bool caseSensitive = false;
int wordCount = 0;
int pos = 0;

string text2 = text;
if (!caseSensitive)
{
	text2 = text2.ToUpper();
	wordToFind = wordToFind.ToUpper();
}
while (pos >= 0)
{
	pos = text2.IndexOf(wordToFind);
	if (pos >= 0)
	{
		wordCount++;
		text2 = text2.Substring(pos + wordToFind.Length);
	}
}

// now count only instances of the exact word
wordCount = 0;
text2 = text;
if (!caseSensitive)
{
	text2 = text2.ToUpper();
	wordToFind = wordToFind.ToUpper();
}
string[] parts = text2.Split(' ');
foreach (string part in parts)
{
	if (part == wordToFind)
	{
		wordCount++;
	}
	else
	{
		char lastChar = part[part.Length - 1];
		if ((part.Length == wordToFind.Length + 1) && (alphaNumbers.IndexOf(lastChar) == -1)) 
		{
			wordCount++;
		}
	}
}

Serialize an Object with XmlSerializer

Ido22-Mar-09 22:25

22-Mar-09 22:25

Hi all,
I have an object called “Report” that I want to serialize.
The saved object will be open at IE browser.
I want to save object from C# code with line at the head:

<?xml-stylesheet href="Report.xslt" type="text/xsl" ?>

How I do that?

I used with XmlSerializer from microsoft.

var serializer = new XmlSerializer(typeof(Report), NameSpace); writer = new StreamWriter(fullpath)); serializer.Serialize(writer, this);

The result is :

<?xml version="1.0" encoding="utf-8" ?> <Report xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://tempuri.org/Report.xsd"> <StartDateTimeTest>22-9-2009 12:00:12</StartDateTimeTest>.....

And i want to get

<?xml version="1.0" encoding="utf-8" ?> <?xml-stylesheet href="Report.xslt" type="text/xsl" ?> <Report xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://tempuri.org/Report.xsd"> <StartDateTimeTest>22-9-2009 12:00:12</StartDateTimeTest>.....

I am very desperate,
Thanks all.

I think on serialization only class members will be serialized...So the other way around is to Serialize the object to a string instead of serializing directly to a file...then you can insert the required stylesheet declaration string and afterwards load the formatted XML into a XML document and save it to a file.

You are fantastic.
Your answer give me an inspiration and i solve my problem by code:

// Load the style sheet. XslCompiledTransform xslt = new XslCompiledTransform(); xslt.Load("output.xsl"); // Execute the transform and output the results to a file. xslt.Transform("books.xml", "books.html");

from Microsoft site:

Gridview, databind retrieving value from database

Hey people. I am currently doing a social portal like Facebook. What i am facing over now is whenever a user makes an update, for example : Posted a new status or note.

Below, when pple click on the Note button, it will display the top 5 updates from the database. But this raises a question. Every update will have an UpdateID, but how do i actually know what updateID are they each.
This is because i allow other users to comment on each of these update. Without capturing the UpdateID, i will have trouble in inserting the right Comments onto the status or note.
Hope you guys understand what i am trying to intepret over here.

You need to get this otherwise how do you expect to find the record to update.

There are number of things wrong here
1 you are asking an ASP ? in the C# forum
2 You have dumped in a large amount of useless code
3 Your code is open to SQL injection - always a bad idea.
