Is the datagrid control the only grid available in C#? I am more familiar with delphi and stringgrids, which allow me to set certain cells, rows, or columns to read-only, different colors, or sizes, etc... Does the datagrid control have any of this functionality? I have only be able to find tutorials on how to view, add, or delete data. Can anyone offer any advice? thanks.

It is good. It enough for normal job. If you want more, you can derive from it and extend it by yourself or buy some third party datagrid.

{
// our helper array
int[] t=new int[a.Length];

// number of bits our group will be long
int r=4; // try to set this also to 2, 8 or 16 to see if it is
//quicker or not

// number of bits of a C# int
int b=32;

// counting and prefix arrays
// (note dimensions 2^r which is the number of all possible values of a
//r-bit number)
int[] count=new int[1<<r];
int[] pref=new int[1<<r];

// number of groups
int groups=(int)Math.Ceiling((double)b/(double)r);

// the mask to identify groups
int mask = (1<<r)-1;

// the algorithm:
for (int c=0, shift=0; c<groups; c++, shift+=r)
{
// reset count array
for (int j=0; j<count.Length; j++)
count[j]=0;

// counting elements of the c-th group
for (int i=0; i<a.Length; i++)
count[(a[i]>>shift)&mask]++;

// calculating prefixes
pref[0]=0;
for (int i=1; i<count.Length; i++)

// from a[] to t[] elements ordered by c-th group

Hi,

I guess you have to write a routine yourself, implementing a join like sql by hand.

You can either write some XSLT to combine the two file or use Linq to XML

HI,
How can I get Oracle Servers names in current computer Using C#. Suppose a list of DBMSs names are appeared in a list box. When I clicked in SQL server data base then it shows all the sql server data bases in my current computer. But now I need when I will click oracl then it will display the servers names and when i click a particular server it will ask for user name and password from me. So currently my main problem is how can I get oracle server name using C#. After getting server name I will be able to do the next steps.

This will help you get a list of SQLservers

just include using System.Data.Sql;

DataTable ListOfServersNames=new DataTable();<br />
var sqlServers = SqlDataSourceEnumerator.Instance;<br />
ListOfServersNames= sqlServers.GetDataSources();

Now the datatable will contain the list of servernames available.

Hi..

I just wanted to know whether there is any way to get collection editor form
inside a another form , without using property grid, since my boss doesn't like the pop up coming up for collection editor, so without triggering any event the collection editor must be placed in a particular location of my form, which i can further edit and add items into the collection list.

Can anyone guide me how can i do this..

Instead of AxMSChart, I will use McShart for .NET 3.5, it's easy and fully managed code + documentation and sample.

Cannot save changes to code programatically

I'm writing a VS add-on which, on activation, is supposed to add a couple of attributes in the App.xaml.
The problem I get is, when App.xaml is opened for editing, everything works fine.
But, if App.xaml isn't opened the changes aren't saved. I went through the code, it still goes through it like it should, it adds the attributes like it should, it even executes the line of code that's supposed to save the changes, except... changes aren't saved Frown | :(

This is an overview of what i do:

<br />
codeState.editPoint.StartOfDocument();<br />
string xmlText = codeState.editPoint.GetText(codeState.textDoc.EndPoint);<br />
<br />
--- add a couple of attributes using XmlDocuments<br />
--- save the changes into a memory stream<br />
<br />
codeState.editPoint.ReplaceText(codeState.textDoc.EndPoint, reader.ReadToEnd(), 0);<br />

Any ideas why?

I think, you must ask at WPF forum.

It's not really a WPF issue. The file just happens to be xaml, the problem would persist no matter the file type.
I thought of asking this in the Visual Studio forum, since I am working on a Visual Studio add-on... but, that's more of a "using" forum, than programming.

XElement vs XmlWriter Question

2-Sep-09 23:03

Hi all,

I am trying to make use of XElement instead of XmlWriter, but I am experiencing some hickups ... Sigh | :sigh:

The XmlWriter code works perfectly .. here it is:

// write the controller element and attributes
foreach (var controller in ControllerList)
{
    w.WriteStartElement("controller");
    w.WriteAttributeString("name", controller.Value.ControllerName);
    w.WriteAttributeString("description", controller.Value.ControllerDescription);
    w.WriteAttributeString("area", controller.Value.ControllerArea);
    w.WriteAttributeString("startdate", DateTimeClass.DateTimeYearMonthDay(controller.Value.StartDate));
    w.WriteAttributeString("enddate", DateTimeClass.DateTimeYearMonthDay(controller.Value.EndDate));
    w.WriteAttributeString("updatemode", controller.Value.UpdateMode);

    // write the reader element and attributes
    foreach (var reader in controller.Value.ReaderList)
    {
        w.WriteStartElement("reader");
        w.WriteAttributeString("name", reader.Value.ReaderName);
        w.WriteAttributeString("readergroup", reader.Value.ReaderGroup);
        w.WriteAttributeString("host", reader.Value.ReaderHost);
        w.WriteAttributeString("type", reader.Value.ReaderType);
        w.WriteAttributeString("startdate", DateTimeClass.DateTimeYearMonthDay(reader.Value.StartDate));
        w.WriteAttributeString("enddate", DateTimeClass.DateTimeYearMonthDay(reader.Value.EndDate));
        w.WriteAttributeString("description", reader.Value.ReaderDescription);
        // end the reader element
        w.WriteEndElement();
    }
    // end the controller element
    w.WriteEndElement();
}

but the XElement code does not produce the same results .. It appends the data to the first controller node OMG | :OMG:

... here is the code:

foreach (var controller in ControllerList)
{
    xElement.Element("plant").Element("building").Add(new XComment(String.Format("Controller: {0} Declaration", controller.Key)));
    xElement.Element("plant").Element("building").Add(new XElement("controller",
        new XAttribute("name", controller.Value.ControllerName),
        new XAttribute("description", controller.Value.ControllerDescription),
        new XAttribute("area", controller.Value.ControllerArea),
        new XAttribute("startdate", DateTimeClass.DateTimeYearMonthDay(controller.Value.StartDate)),
        new XAttribute("enddate", DateTimeClass.DateTimeYearMonthDay(controller.Value.EndDate)),
        new XAttribute("updatemode", controller.Value.UpdateMode)
        ));
    // write the reader element and attributes
    foreach (var reader in controller.Value.ReaderList)
    {
        xElement.Element("plant").Element("building").Element("controller").Add(new XElement("reader",
            new XAttribute("name", reader.Value.ReaderName),
            new XAttribute("readergroup", reader.Value.ReaderGroup),
            new XAttribute("host", reader.Value.ReaderHost),
            new XAttribute("type", reader.Value.ReaderType),
            new XAttribute("startdate", DateTimeClass.DateTimeYearMonthDay(reader.Value.StartDate)),
            new XAttribute("enddate", DateTimeClass.DateTimeYearMonthDay(reader.Value.EndDate)),
            new XAttribute("description", reader.Value.ReaderDescription)
