Anyone tried this?

If so, how does it compare to PowerCollections? It seems more powerful and I get the impression that it has a steeper learning curve.

Personally, I have never had much use for it, and it seemed unnecesarily bloated. Thanks for the link Smile | :)

Declaring control events in XML file

Hi All

I have a blank windows form running on .net 1.1. At runtime, I load controls dynamically from an XML file which is all fine. I now need to register events for the controls dynamically define somewhere in the XML file. Is this possible? As my requirement is to generate the controls and define its events in XML file, I don't want to use factory model.
I have tried using addhandlers and eventhandlers but no success yet.

Thanks

I really hate to say this, but what you are trying to do was already done for you by Marc Clifton : http://myxaml.com/[^]

This has it all, eventhandlers, components, etc. all in XML. Great tool and very mature Smile | :)

You write a event handler for the Key_Press (or Key_Down) event for the control you wan't to capture.

Calculation Problems

Hi all,

I've been working on a Graph class for our web stats system and i'm having a few problems.

After getting some help of a few guys/gals (not sure) from here, I solved many problems and then hit another one.

I have currently got a class that generates an image of a graph which has X and Y Axis labels all correctly placed.

Now my problem is, how can I display my values in a staticly sized image?

My working space is 150hx650w. My X and Y Labels are all placed in the right place, and I need to calculate how tall I need to make my bars to reflect their value.

So my values are now : 0,0,4,0,90,172,0 (graph shows stats for the last 7 days)

At first I thought 150*value/100 would give me a percentage of the height, which I could simply draw

but when I tried it against the 172, my return value was 258.

Has anyone got any idea's on how to solve this. Maths was my strong subject at school, but i've forgotten most of it.

Thanks everyone.

Gav

bar = bar_max * value / value_max

For example:
bar = 150 * 172 / 172 = 150
bar = 150 * 90 / 172 = 78

Okay, if figured out how to run a url directly from C# but i opens up my default web-browser. I want to run the url without the having the user see the url. i'm using the "Process.Start(URL)" to run the url.

Is there a way to not open any windows (like the web-browser) and still run the url?

Request = ((HttpWebRequest)(WebRequest.Create(URL)));
ResponseReader = new StreamReader(Request.GetResponse().GetResponseStream());

when i run the code it says: "the underlining connection was closed. The remote name could not be resolved"

I think it's saver to change the select Query and translate the I or A values into true or false. You might want to checkup on the CASE OF syntax for SQL 2000/2005.

I have a dataGridView and just three rows.

I wrote dataGrid_RowEnter and dataGrid_RowLeave event. Basically i am changing the color to red of the row in the Row_Enter event and in the RowLeave and changing the color back to no color. I have also button in the same form. I have not written any thing on the button. but even if i click the button RowLeave event is firing and changing back my color. Is there a way around it. Is this the
normal behavior.

Thanks
kal

If your button is not within the row then yes it is normal behavior, you have left the row to click on the button hence the RowLeave event being fired.

Hello,

Yes you have a null ref. exception here.

wind[0] and wind[1] are not initialized

//Constructor code
for(int x=0;x<wind.Length;x++)
{
wind[x] = new int[10]; //for example
}

Hope that helps!

All the best,

Martin

You forgot to allocate the size of the second dimension of variable wind.
You need to do something like this:

int[][] wind = new int[2][];<br />
wind[0] = new int[3];<br />
wind[1] = new int[5];

Set the size of the first dimension to 2 (you've done that). Then you need to set the sizes of the second dimension for each of the elements (!) in the first dimension.

By the way, if you want the sizes of the second dimension to be the same, you might consider using a two-dimensional array like this:
int[,] wind = new int[2, 3];

Thank you for the information about the 2D-array. (never used it before)

How do I get access to a spezial array?
(int[] intarray = wind[0]) //doesn't work
