Hi im using a data view to populate my datagrid but am unable to use DataGridTableStyle. When populating my datagrid directly with a DataTable I set the DataGridTableStyle.MappingName to my DataTable name and am able to change the look of the table and columns without any trouble. When using the dataview i get no errors just a blank datagrid. Is it not possible to use the two together?
Here is the code anyway, if someone could spot my mistakes it would be great!
**Working Code**
DataSet ds = new DataSet();
ds.ReadXml("xml.xml");
DataGrid dg = new DataGrid();
dg.DataSource = ds;
dg.DataMember = "Players";
DataGridTableStyle dgts = new DataGridTableStyle();
dgts.MappingName = "Players";
dgts.RowHeadersVisible = false;
dgts.PreferredRowHeight = 24;
dg.TableStyles.Add(dgts);
**Broken Code**
DataSet ds = new DataSet();
ds.ReadXml("xml.xml");
DataView dv = new DataView(ds.Tables["Player"]);
DataGrid dg = new DataGrid();
dg.DataSource = dv;
//dg.DataMember = "Players"; **this line causes error**
DataGridTableStyle dgts = new DataGridTableStyle();
dgts.MappingName = "Players";
dgts.RowHeadersVisible = false;
dgts.PreferredRowHeight = 24;
dg.TableStyles.Add(dgts);
the broken code causes no errors just displays an empty grid (if i comment out the DataGridTableStyle code the grid dispalys just fine)
Thanks in advance!!

HI,
Iam looking for an application very similar to "Microsoft Application center", but also should be able to perform some tasks like send emails, send sms text messages about the test results.
Any info on this will be great.

OK I want to know the best way to go about doing this as there as so many ways and they tend to get messy.
All I want is a way to add entries to a table, with Field1, Field2 etc.. (like a database table), be able to arrange by name, filter by first letter of Field1, and most importantly to be able to edit the values in the actual table and save the results.
I am guessing a DataGrid linked to a MSACCESS db, but is there another better way? I don't like the lack of usability of the DataGrid for layout and functionality. Also I need fields with an URL link that when you click it can open it

OK we have an old quaderno at work (palmtop) that has DOS 5/6 not sure which, and we use it to basically edit, and transfer text files to a PC and the CNC machines via serial using intersrv to get files to and from the PC, and a program called PSISTEM to get the files off the CNC machines, which I think just uses intersrv as an underlay.
My question is, I can create a program for the PC as normal but how would a create a network to transfer the files to the palmtop vai COM1 using the serial cable, bearing in mind the palm only has dos 5/6.
Also can I create a program to easily select and edit files in dos instead of using dos commands to browse to the files and then using the dos EDIT? Maybe learing some simple qbas or something?

How get data (form Image) to display image into our application from a device named Webcam which is capturing a person sitting on the computer. Which class does support this ?

Hello
The best way to do it is to use DirectShow. You can try to interop it or to use managed extension of DirectShow 9.
There are couple of article on CP about DirectShow usage in C# applications, for example here is one [^].
You can look at my "Motion Detection" article for a sample of communication with local capture device such as USB webcam.
With best regards,
Andrew

I belief, that most Webcams support TWAIN and/or WIA as interface. Here in CodeProject you finds Wrappers for TWAIN and WIA.
TWAIN is a normed API to read still images like scanner and webcams.
WIA is the newer API (and supported since Windows 2K).
See: .NET TWAIN image scanner
See: WIA Scripting and .NET

Hello
I think that my article "Image Processing Lab in C#" can be a good start for you. Also there is series of article from Christian Graus about image processing.
So, first of all you can try some color filtering techniques to locate face skin regions. It can be done using RGB or HSL color space. There are filters in my lab for it. Or you can try other color spaces to achieve this task.
For eyes localization you can try also some combinations of color filtering. After binarization you can use blob counter/extractor to locate each object (eyes in your case). The idea of blob extractor can be inspired by Connected Component Labeling.
With best regards,
Andrew

Strange people are here sometimes. Just put the "1" mark without any comments and that's all.
I've made so bad comment? There is something wrong? So, why not just to reply me with your ideas? I thought that it is the place for sharing ideas. And if one's idea is not the same as yours, than it is not a reason just to put "1".
May be I am wrong? So, correct me, please.
With best regards,
Andrew

Are all DLLs in the same directory as the main executable module? If they are, then the application should work. If they are not, then you will get the described exception.

About idea.
You can define a color range for face skin. For example, you can define a range around yellow color and use it for filtering. So, only pixels, which color falls into the specified range, are preserved and other pixels are filled with background color.
There are many works utilizing the idea. And different color spaces were researched for applying to the task.
You can look at the survey for more information:
"Detecting Faces in Images: A Survey - M. Yang, N. Ahuja, D. Kriegman"
