Hi Mav,
Thanks for your reply. I really appreciate this. You perfectly understood what I was trying to create. I tried your code and it works fine as well. But here is the problem.
You have tried to create an ellipse. But when you try to create a pie what happens is it gives the applies the surround color to all the edges. which basically is taking away all the effect.
I am sure if you just you can re-produce what is the problem if you can simply replace all your
FillElliipse calls to this.
FillPie(xxx, this.ClientRectangle, 0, 90);
Thanks Again,
Apratim

So basically you want a 3D pie with rounded edges, right?
That's something that is beyond the scope of (rather) simple PathGradientBrushes.
You'd have to paint your pie chart as composition of true 3D objects, which is _a_lot_ more complicated than just filling a few ellipses and applying some clever gradients...
I strongly doubt that a believable effect can be achieved by applying gradients on the pie slices, sorry...
Nevertheless, you could take a look at this article here:
3D Pie Chart[^] for some inspiration.

Hi,
I have found some solid details on Windows Mobile 5:
http://www.bentuser.com/article.aspx?ID=310[^]
I was wondering if anybody has tried the .NET Compact Framework 2. Dare I install it on my Pocket PC?
Thanks,
Andrew

Interesting article. The only change that will effect me is that they changed everything from gray to blue. The rest sounded more like *fixes* than new features.
I'd try CF2 on my PPC only after a full backup with Activesync.

Hello,
I have a datagrid, and it's been populated with numbers.
I want to display the number 4509223 like that - 4,509,223 in the grid.
I tried to use:
row[i] = Math.Round(Convert.ToDecimal(Convert.ToDouble(val["NumUnits"])*mult), 0).ToString("n0");
But it does not convert the number to the above notation. Any ideas?
Thank you,

Create a CultureInfo object for the culture you want, and use that in the ToString() call. Alternatively, create a custom NumberFormat object with the settings you like.
Why in the world do you convert the value to the data type Decimal?
Just take the double value, skip the conversions and rounding, and just specify how it should be displayed.
---
b { font-weight: normal; }

|
|

string currencyValue = "4509223";
NumberFormatInfo numberFormatInfo = null;
double currency = 0.0;
currency = Convert.ToDouble(currencyValue);
numberFormatInfo = new NumberFormatInfo();
numberFormatInfo.CurrencyDecimalDigits = 2;
numberFormatInfo.CurrencyDecimalSeparator = ".";
numberFormatInfo.CurrencyGroupSeparator = ",";
int[] groups = new int[1];
groups[0] = 3;
numberFormatInfo.CurrencyGroupSizes = groups;
numberFormatInfo.CurrencySymbol = "";
string formattedCurrencyValue = currency.ToString("c",numberFormatInfo);

Still, when you assign value to a dataview which is the datasource for a grid, the value comes up as a number without separating commas.
Any ideas?
Thank you

That would be great, by the way here is the code that I use:
row[totalIndex] = Convert.ToDecimal(row[i]).ToString("c", numberFormatInfo);<br />
Debug.WriteLine("VAL: "+Convert.ToDecimal(row[i]).ToString("c", numberFormatInfo));
So, Debug.Writeline statement gives me the proper value, but the value in datagrid (row[totalIndex]) is displayed without comma separators.

Hey
Try this
if ( column.IsMoney )
{
NumberFormatInfo numberFormatInfo = null;
numberFormatInfo = new NumberFormatInfo();
numberFormatInfo.CurrencySymbol = "";
this.dataGridColumn.Format = "c";
this.dataGridColumn.FormatInfo = numberFormatInfo;
}
else
{
this.dataGridColumn.Format = "";
this.dataGridColumn.FormatInfo = null;
}
|
|
|
|
|
Great. Worked like a charm.
Thank you very much. Is there an option on NumberFormatInfo object, so I don't have .00 following the numbers? I don't want the decimal potion displayed, since all of my dollar values are rounded off already.
Thank you again.

I figured it out. Thank you for your help.

Sorry, a very quick question.
If I have a currency symbol in fron of the values for each of the columns, can I do something, so that the symbol does not show up in fron of the values for the first 5 rows, and then shows up for the rest. I guess to do that I have to override the paint method. ANy ideas?
Thank you.

This is very difficult to achieve. You cantry to override
GetColumnValueAtRow and SetColumnValueAtRow.

I want to display a "table" of data on the screen. This "table" may contain 2000+ entries. I want to sort the columns, highlight an entire row, programmatically select entries, and be able to determine which row (or at least the key column) that was clicked.
I can do all of this using a ListView, but it is slow to display when I loop through all record from the database and add to the ListView. When I use a DataGrid, it is much faster loading, but I can't determine how to change the column headers or more importantly, how to determine when a record is clicked and/or which record is selected.
Can someone provide a pointer or two, or tell me I'm approaching this from the wrong angle?
Thanks,
Glenn

I found this article at
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dv_vstechart/html/vbtchTopQuestionsAboutASPNETDataGridServerControl.asp[^]. Quoting from the article:
The Web Forms DataGrid control is not the same as the Windows Forms equivalent. It is a common (and not unreasonable) assumption that they are the same control, or at least have identical functionality. However, the entire programming paradigm for Web Forms is quite different from that for Windows Forms.
I didn't mention it explicitly, but this is a Windows Forms application.

I am trying to write an automation routine to upload a file to a secure webmail system. i have figgured out how to get the information into the fields available, but i am unable to figgure out how to click a javascript button. I am using the axWebBrowser control. any thoughts how to click login?

Once you get the document object you can get the button element using the all collection or walking the DOM until you get the button object. Then you just use the IHTMLElement click method to simulate the click. Make sure you use the IE interop objects which come with the framework rather then generating your own. They have an easier to use object model.

How do you walk the DOM? I cant figgure out how to use the ALL collection because it needs a name and what i am trying to click on is a link not a button.(foud this out after ripping appart the HTML)the link activates some javascript.
|

Even easier then, you can use the anchors collection of the document object to find the link you need, then just call the click method on the object.

Awsome. thanks. now my only problem is how to force an INPUT Type=file to a specific value. according to the help, the value is read only from the programatic end.

I have also found that, after making an app that automates a process of acessing a web site to be able to download files from the site, as well as delete them, u can manaully POST the data to the server and get the right response, this can be used to be able to upload and download files, its a bit of a mess sometimes (because of the POST data u may need) but u can use apps like Fiddler http://www.fiddlertool.com/fiddler/[^]
its a good app for viewing requests and response across the net.
hope that helps a bit
