Hello
After some modification to your code it compiles. yes you can have generic delegates in attributes, yet why?
Here is your code modified:
public class MyAttribute : Attribute
{
public delegate T updater<T>(T myVar);
}

I have a windows application with a hosted web browser control, and need help regarding an issue:
The simple details:
Is it possible to have a hyperlink in a web browser control (within aforementioned windows application) output the hyperlink as text to the windows application it is hosted in without processing the link?
i.e. instead of http://www.microsoft.com/Any_Article.pdf opening a PDF reader, it outputs the html as a string to a messagebox, without opening the PDF reader program.
The in-depth details:
I have a tabControl with an InfoPath form control (Microsoft.Office.InfoPath.FormControl) on tabPage1 and a webBrowser control on tabPage2. I can programatically open any infopath *.xml form using C# (including not letting the form open as read-only) or fill out a new form from a *.xsn form template, and in the browser I can navigate (using custom buttons) our sharepoint site which hosts the xml forms. The problem is that IE6 opens the *.xml forms using Mircosoft Office InfoPath, and in my hosted application, I'd like the string of the link returned so I can open it within the form control, without (another) InfoPath starting outside of my app. Maybe, I should force the user environment to use a different program to open an *.xml file, a program that I'd write, that somehow redirected that link as a string back into the original windows app???

Hello
Well, you can get the document of the web borwser using the Webbroser.Document property. Cancel the navigation, get the URL, now either send a webRequest yourself and get the webresponse as a stream, or use the WebBorwser.Document mentioned above.

Thank you very much. I'll try to hack something together with your suggestions.

Greetings,
I've been busy with other things, and just yesterday got around to doing what you suggested. I tried searching the statustext of the link just clicked, and stopping it immediately if it matches a desired string. I put something like this:
if (webbrowser1.statustext ends with ".doc ") /*not what I actually have, but logically similar*/
{
webBrowser1.Stop();
MessageBox.Show("This shouldn't open MS Word after you click 'OK'");
}
But after you click 'OK,' MS Word (the full windows MS Word application) opens the document listed in the link that was clicked, and not in the hosted form control within he custom application I'm developing; programatically, though, I am able to open documents (local and networked) in the hosted form control with ease:i.e. formControl1.Open("C:\test.doc"). I think I must be searching the wrong string? maybe telling the wrong thing to stop???
I did some more searching online, and the closest thing that I can find is a tutorial about using a button, an ActiveX control, and preventing the OS from opening Word, but opening it in your custom ActiveX control. This is similar to what I'm doing, but instead of the button, I'm using a hosted web page (browsing a sharepoint website hosted within our domain) and I'm not using ActiveX. (Here is that link: http://support.microsoft.com/kb/304662)
Thanks for any info you can offer.
If this is still unclear, I'll be more than glad to explain it better.

It's about relationship, not performance. You should get the relationship right. Inheritance describes that B is an A, but aggregation describes that B has an A. For example, a car is a vehicle, but a car has (is not) an engine.

Iam trying to paint a button to get a shade in a button. Iam using a LinearGradientBrush. The code below Worked but it is taking away the
button1.text also.How do i get the text to show after the button is
painted.
void button1_Paint(object sender, PaintEventArgs e)
{
Graphics g = e.Graphics;
Rectangle rcView = this.ClientRectangle;
using (LinearGradientBrush brush = new LinearGradientBrush(rcView, this.ColorStart, this.ColorEnd, this.GradientMode))
{
g.FillRectangle(brush, rcView);
}
base.OnPaint(e);
}
ColorStart and ColorEnd are basically colors. Iam trying shade of the
color from lighter to darker across the button. So my ColorStart is a
little lighter color and ColorEnd is a Darker color.
Thanks
Kal

Form.ShowDialog

1- How do you do to open more than one form at a time? Just don't do it that way.
2- Use the ShowDialog method to show the form.

Hi,
I am searching for a good WYSIWYG Html control for last 6 months in Google, I did not get a good one. Do anyone know a good Win form .NEt 2.0 Control for Html Editing.
Thanks
|
|
|
|

There are *tons*. You can even host the IE control and use its inbuilt editor if you want.
Maybe if you told us what you don't like about the currently available ones we could narrow it down.

Hello,
I did not find any good one even commercial. Which already has a toolbar and good API. I did not find any way to use IE control as an editor. would you please show me in little more details.
Thanks

I've read an article about fast pixel processing[^] posted in codeproject.
As we all know, the GetPixel() and SetPixel() functions have a lot of overhead.
So... The most common solution I've found so far was to lock the pixels in memory and perform calculations using unsafe code and pointers.
If you look at the source code provided with the article mentioned above, you'll see that AndrewVos ,the writer, does lock the pixels in memory, but instead of looping through pixels using unsafe pointers, he marshals them into an array.
I'm sure that the safe and managed code is better.
After all it IS "safe and managed". 
But is it slower/faster than unsafe code?
Thanks in advance,
Shy.

If you are going to manipulate a large amount of pixels, the marshal overhead will be small. For justa few pixels, unsafe will still be the fastest.

Hello
You should put your code in the Form.Shown event. Yet, notice that it needs .Net version 2.0
If you don't have version 2.0 you may try the Activated event, yet it will be fired evry time you code is activate it. So if you want to run it once, make a bool and set it to false after the first time.
