how to manage the click event of a dom node (ie an image) in a iexplorer web page ? - C# Discussion Boards

Hi,

I needed a list view that was capable of showing multiple icons in the first column in details view. I managed to create this using owner draw and gdi+ and overall it was easy to do. The only problem I've run into is when the mouse cursor moves over a listview item for the first time, the listview attempts to redraw the item yet does not redraw any of the subitems.

This is an acknowledged bug with the control itself and is mentioned here: msdn library. The article also lists two workarounds, one of which isn't very effective, which I have tried. I was just wondering if anyone knew of another way to handle this issue?

Thanks.

Hi,

I find that I can drag an jpeg image from IE to MSWord document, but can't drag an image from IE to a c# window form which has already added with both the dragOver and dragDrop events. But I can drag an the image from MSWord document to the C# window form. Why ?

Summary for dragging and dropping jpeg image
1. from IE to C# window form : failed
2. from IE to MSWord : OK
3. from MSWord to C# Window form : OK

Thanks

What is the code in your DragDrop event?

Thanks for ur reply.

The code for the drag drop is

void button1_DragDrop(object sender, DragEventArgs e)
{

object a = e.Data.GetData(DataFormats.Bitmap);
this.button1.Image = (Bitmap)a;
}

I looked into this a little. It seems that when you drag an image from MS Word, it is in fact a linked or embedded OLE Object. The data object contains a CF_EMBEDDEDOBJECT format that needs to be extracted using "standard OLE techniques". I've never done this before, sorry I can't really help you with it. However, this does explain why you are able to drag and drop images from IE to Word and Win Forms, but not Word to Win Forms.

SqlBulkCopy performance

Has anybody done performance testing on the SqlBulkCopy class?

I'd assume that, like many classes that operate on bulk data, up to a certain point, doing individual SQL Insert statements (by enumerating and calling individual ExecuteNonQuery calls) will be more efficient than using SqlBulkCopy. But at some point, SqlBulkCopy will become more effiecient. In other words, something like this:

NumberOfRecords < M : Enumerated calls to ExecuteNonQuery is more efficient.
NumberOfRecords > M but < N : Doesn't matter which you use, as both are about the same.
NumberOfRecords > N : SqlBulkCopy more efficient.

Anybody know about what M and N would be? I did some Googling, but didn't come up with much in this regard.

Hi, everybody!
My problem is that:
I have put in a dom node, representing an image, in a web page through c sharp, but how could I manage the click of the image?
I would like to bind the click event on the image to some work that I encapsulated insiede a c sharp method...but how could I bind the click event to some desired work? Am I to encapsulate thus work insiede an other language method? like javascript for example? but how if I'm writing a c sharp program?

I hope to have been rather clear, because I'm italian and I don't know if I explained my trouble good way, I hope so
thank yuou all in advance.

Hey, wonder if any1 can help me, its a fairly simple issue to deal with so im told but ive spent ages trying to work this out, but havnt got anywhere. Cry | :((

So was wondering if sum1 could lend a hand.

Basically ive an array of strings and i want to randomly select a word out of this array

Once the word is selected i then need to split the word into separate characters, so I can check the users input against each letter until they finally guess the word

I know it seems alot to ask, but id really appreciate it if sum1 could provide some example I could follow in order for me to get mine working...

Thanks in advance

 Random rand = new Random();
string[] somestrings = { "Hello", "World", "From", "An", "Array" };
string randString = somestrings[rand.Next(somestrings.Length - 1)]; // get a random string from the array
char[] characters = randString.ToCharArray();  // get an array of the characters from this particular string

Before you start writing an ounce of code, make sure you have a game plan (i.e. psuedocode or flowchart) that expresses your logic. Once you're fairly certain your logic is correct, it'll be pretty easy to convert it to C# (or any other language).

You could start by posting your logic and we'd be happy to help you refine/verify it.

I would do something like this.

public bool isMatch()
{
bool Matches = false;
string[] asCompare = new string[4];
asCompare.SetValue("First0", 0);
asCompare.SetValue("Second1", 1);
asCompare.SetValue("Third2", 2);
asCompare.SetValue("Fourth3", 3);

Random ran = new Random();
int iVal = ran.Next(asCompare.Length - 1);

string sValue = asCompare[iVal];
char[] chars = sValue.ToCharArray();
string sCharTracker = "";

for (int i = 0; i < chars.Length; i++)
{
sCharTracker = chars[i].ToString();
//Matches = //you would probably do your compare with a method call here//
}

return Matches;//This will be if it matches or not//
}

That's a one-liner. Smile | :)

char[] chars = (new string[] { "some","words","in","an","array" })[(new Random()).Next(5))].ToCharArray();

By "text editor" do you mean a TextBox? If so, see this[^] link.

You are providing a path that is in the wrong format.

If you supply any information about what you are trying to do, or what your code looks like, it might be possible to say anything more specific than that.

Identity in Oracle

Hi all

How can I retrieve the last inserted record identity in Oracle. In sql server it's SELECT @@IDENTITY but how do we do it in oracle.

Thanks,

One way is to create a SEQUENCE, cl_entry_seq, query this sequence for the next value, cl_entry_seq.nextval, and store this value into a stored procedure variable, v_entry_key by executing:

select cl_entry_seq.nextval into v_entry_key from dual;

Then you use the value of v_entry_key as your identity value in your INSERT statement.

Hello,

I am in the middle of a eLearning System project. Now I want to initiate a Video Conferencing system between 2 computers. What is the most efficient way of achieving this. I was looking at few options.
Should I use DirectX OR GDI+? Can I use Flash to do the same?

Thanks
