Remember to call Close on the form once you're done with it (after calling ShowDialog), otherwise you'd be leaking resources.

Hi,
Im writing a few things to an xml file. But if i repeat this, it removes all previous data in my xml file with new ones.
How can i prevent this? I want the data being appended.
Thanks in advance!

Your question cannot be answered. Yuor code is overwriting the nodes, or you have some other problem with persistence. We'd have to see the code to know.

Hi,
This is my xml class code:
class XMLWriter
{
XmlWriterSettings settings = new XmlWriterSettings();
DateTime dateTimeNow = DateTime.Now;
XmlWriter writer = null;
public XMLWriter()
{
this.settings.Indent = true;
this.settings.IndentChars = "\t";
this.settings.OmitXmlDeclaration = true;
this.settings.NewLineOnAttributes = true;
this.settings.Encoding = Encoding.Default;
this.settings.ConformanceLevel = ConformanceLevel.Fragment;
}
public void WriteStartElement()
{
this.writer = XmlWriter.Create("Testing.xml", settings);
this.writer.WriteStartElement("Information");
this.writer.WriteElementString("DateOfBuilding", dateTimeNow.ToShortDateString());
this.writer.WriteElementString("TimeOfBuilding", dateTimeNow.ToLongTimeString());
}
public void WritingToXMLDoc(string elementString, string writeToXMLDoc)
{
this.writer.WriteElementString(elementString, writeToXMLDoc);
}
public void WriterEndelementString()
{
this.writer.WriteEndElement();
this.writer.Flush();
if (this.writer != null)
this.writer.Close();
}
}

You won't be able to persist old data in the file when using the XmlWriter . Use XmlDocument and associated classes to deal with this.

OK, well, this code creates a new XML document every time. You need to abandon this approach and use XMLDocument to load your document if you want to insert nodes into an existing document.

Hi,
Thank you guys!
I'll try that!

Hi gurus,
As the subject says, I'd like to know how I can convert and manipulate 15bits encoded colors to 24bits encoded colors?
For example 0x7fff is white...
Can any one show me a piece of code please?
Best regards.
Fred.
There is no spoon.

Well, you really just want to shift each value by 9 bits, so 0x7FFF << 9 is going to be 0xFFF700, which is the best you can do.
I've never heard of 15 bit color ?

he probably means 16 bit... (I hope )
|
|
|
|

Is 0x7FFF 16 bit white ? I didn't think so.

no, it isn't. but 0x7FFF is 16 bit no?
|
|
|
|
|
If the first bit is a 0, yes. 0xFFFF is 16 bit white.

Yeah, I am. What uses 15 bit ?

OK - so it actually packs 15 bits side by side ? b/c surely that's much messier to unpack than 16 bit, which is 2 bytes, not 1 7/8 bytes ?

I think either still use all 16 bits.
|
|
|
|
|
No, the high but was just unused. I suspect the intent was to make the pallet symetric by using 5 bits for all three colors.

I have data in a SQL Server™ 2000 database and I would like to write a Windows® Forms app to allow users to export and save the data to Microsoft® Excel. How can I do this using C#?
|

Get the Data in data set,data tables and set relationships etc.using data adapter.
Next step is to write into a file using stream object like FileStream
// Get a FileStream object
FileStream myFs =
new FileStream
("myXmlData.xml",FileMode.OpenOrCreate,FileAccess.Write);
You can loop through the rows of your data table and write xml elements and nodes to the xml file
or else
you can use dataset's writexml property

Hello Uma,
GridView may or may not have something similar, but ComponentOne's FlexGrid for .NET allows you to load an Excel sheet directly into the grid via the LoadExcel Method. There are few different possibilities for parameters. For example:
'Load the first sheet in the file
FlexGrid1.LoadExcel("myFile.xls")
'Load a specific sheet, sheetname1, into the grid
FlexGrid1.LoadExcel("myFile.xls", "sheetname1")
You can also add a FileFlags parameter, but it is difficult to explain here. If you are interested, check for FileFlags Enumeration in the FlexGrid help file. If you think that you may want to try FlexGrid, you can get more information and download an evaluation here http://www.componentone.com/products.aspx?TabTypeID=1&ItemType=1&PanelIndex=12&ItemID=53459&SubCategoryTypeID=0&TabMapID=9&TabID=11[^].
