Hi,

Please help me with your ideas for the following

1.Does .net support for WEBDAV protocol?
2.Can I implement .net remoting using WEBDAV protocol?

Right now I implemented .net remoting using TCP/IP protocol.It is working fine.I need to change this to support the WEBDAV protocol.

Please help me.

1. There are several third party frameworks bringing webdav-apis for .net
2. ???? AFAIK WebDav is a protocol for file-operations over web. How should this work together with remoting?
3. Please don't crosspost.

Regards
Sebastian

display the items in a combobox

Hi,
Is it possible to display the items in a combobox in the same way windows does it when you go to open a file. If you start typing text a dropdown is displayed with files that match the text being entered.

You can use AutoCompleteSource property of Combobox class.

How to insert text to GIF and animate the text ?

Hello

I have the following code which inserts user text into a GIF image:

this.DestinationImage = new Bitmap(this.SourceImage.Width, this.SourceImage.Height, PixelFormat.Format32bppArgb);

using (Graphics graphics = Graphics.FromImage(this.DestinationImage))
{
//Draw the original image.
graphics.DrawImage(this.SourceImage, 0, 0);

//Used to write smooth text.
graphics.TextRenderingHint = TextRenderingHint.AntiAlias;

//Write the title you want.
graphics.DrawString(title, titleFont, titleBrush, left, top, StringFormat.GenericTypographic);
titleFont).Height;
//graphics.DrawString(body, bodyFont, bodyBrush, left, yTop, StringFormat.GenericTypographic);

//Free the resources.
graphics.Dispose();

}

I need to know how to animate the text (ie.- flash it, change its color, etc.)

Hi,

your code modifies the destination image, so if you save it with DestinationImage.Save() the file would contain both the original image and the text written on top of it; however your code does not show anything, so how could it flash?

if you want to see some animation effects on screen, you should make sure everything gets painted;
one way to do it would be to have a PictureBox that shows the original image, then use its Paint event to draw something on top of it. If you install a Windows.Forms.Timer to periodically invalidate the PB, your Paint handler would be called again and could paint something slightly different to get the animation effects you want.

Then you have to use a MemoryStream instead of a FileStream.

How to catch browser close?

I try following script but, it's accept postback events...

</script>

First: this is no javascript forum
Second: search on google for an anwser
Third: here you go:

<head>

<script language="javascript">
<!--
 function LoadMe()
 {
  self.close();
 }
// -->
</script>
</head>
 
<body onload="LoadMe()">
<div align="center">

<a href="javascript:window.close()">Close</a>
 
</div>
</body>

My question is "How to catch browser close ?".

It's mean how can I detect press close button on the browser.

Thanks...

If your question is 'how can I detect press close button on the browser' you should question that in stead of 'how to catch browser close'.
And maybe I've allready given you the anwser: <body onload="LoadMe()">
I even wrote an implementation for you, but you're probably not interested in that.

Thanks for care Deresen.

But I try following script but, it's accept postback events...

<script type="text/javascript">
window.onbeforeunload = function()
{
window.open('Logout.html');
}
</script>

I must be foud diffirentation between browser close and "Postback".

Thanks again...

Generic Collection in C#

What is Generic Collection?
Why we use Generic Collection?

Generics are like lists.

You can store some defined typed data, and then make a lot of operations like a sort, find an item, remove / add items, extract all items, etc...

You seem to have overloaded the word "generic"

The ArrayList is not a Generic object in the OO sense of the word. To remove the ambiguity you may like to call them "general" rather than generic.

Did you mean "same type of object". I've never found a situation where I would repeatedly store the same object in a list.

"Generic Collections (Array Lists) existed before non Generic (i.e. Lists)"

Actually, lists (List <T>) are generic and array lists are non-generic. You either got them mixed up, Or you're using the term "generic" to mean "any type". In any case, .NET uses the term to mean parameterized types.

That is like saying "the word left or right is irrelevant". It isn't irrelevant. Generic has a very specific and well defined meaning in OO languages. If the OP used it in error then don't repeat the error. Use the correct term otherwise the OP will continue to use the word in error and cause more confusion later.

FYI you could have a situation where you want to store the same specific object in a list. The list does not keep copies but actual references.

Are you trying to teach me C#? I am well aware of this. I just said I've never found a situation where I would want to do this.

Collin Jasnoch wrote:
This is how you can keep ojects alive so the GC does not hit them.

Adding an object many times to the same list will not affect the way garbage collection works. Just one reference in the list is sufficient for the GC to ignore the object so long as the list itself is referenced.

I doubt that. It is rather difficult even to find an authoritative definition of "object oriented language".

But if you do have an authoritative definition then I would for one would like to see it.
