Hello
In System.Xml namespace there are two classes: XmlReader and XmlWriter.
Use them to make the xml file and write the data to it.

Use the ToString method of the DateTime class to create the string representation of the date and the time.
As you have used the exact format that the ToString method uses, it's easy:
daDate.ToString("ddMMyyyy")
and
daDate.ToString("HH:mm:ss")
---
b { font-weight: normal; }
|
|
|
|
|
Using daDate.ToString("HH:mm:ss") is a risky choice as ":" is a placeholder for the time separator. Hence for example Italian regional settings would give something like "21.17.48" instead of "21:17:48". Even in a fixed region users could simply break the format by changing their regional settings. Always provide a IFormatProvider, typically CultureInfo.InvarientCulture. If you create your own CultureInfo instance to do the formatting, remember specifying "false" to disallow custom overrides.
I assume this is a fixed XML format that MUST be followed? If it is I guess you do not have a choice, but if it is in ANY way possible to influence the format do so, as it is basically as wrong as it can be.
When storing dates as strings there are two formats you can use: "yyyy-MM-dd" or wrong. "ddMMyyyy" clearly belongs in the "wrong" category as it is ambigious and it doesn't even sort correctly. When storing date and time, preferably write them into a single entry with the ISO format.
If you use the XmlSerializer, just serialize/deserialize a DateTime object and it will use the correct ISO format.

Yes, you are right.  I didn't think of that.
The character should be quoted to be interpreted as a literal:
"HH':'mm':'ss"
As the format now contains no culture variant components, it's not affected by any cultural differences.
Using a format provider doesn't affect the output in this case, it's only encouraged for programming style. If no format provider is specified, the CultureInfo.CurrentCulture is used, as there exists no formatting without a format provider.

b { font-weight: normal; }

I assume that you already know how to write an XML output.
So to segregate the Dat and time, you can use the DateTime class to get the date and time seperate portions from the DateTime.Now
Just take out the time and date component from the supported methods

Im not sure if this is the right place for this post, if not I apologize in advance this is my first time on the forum.
My question is - I am trying to write an Image Viewer program that reads the file paths from the file system and stores them in a list. Then it loads the first 25 images into an Image list(the 25 can be set to whatever I want.). That all works fine. The problem is when you get to the end of the 25 and its time to add more images. It works but is EXTREMELY slow. I cant seem to figure this out and have been playing with it for a while now. Any insight would be appriciated. Heres my code for adding to the buffer -
public void vScrollBar1_Scroll(object sender, ScrollEventArgs e) {
Thread addThread;
if(CurrentIndex <= BufferPadding / 2 + 1) {
CurrentIndex = vScrollBar1.Value;
PictureBox.Image = BufferedImageList[CurrentIndex];
} else {
if(CurrentIndex >= BufferPadding / 2 + 1 && CurrentIndex < ImagePathList.Count - 1) {
CurrentIndex = vScrollBar1.Value;
PictureBox.Image = BufferedImageList[BufferPadding / 2 + 1];
addThread = new Thread(new ThreadStart(AddToBuffer));
addThread.Start();
}
}
}
public void AddToBuffer() {
BufferedImageList.Add(DICOMImage.FromPath(ImagePathList[CurrentIndex]));
BufferedImageList[0].Dispose();
BufferedImageList.RemoveAt(0);
}
Thanks in advance

Hi there,
I have been trying to start some processes from my Windows service which is a multithreaded application and uses threadpool. I am able to start upto 24 processes (using ProcessInfo) but when the service try to start 25th an Application execption is logged in the eventlog:
Event Type: Error
Event Source: .NET Runtime
Event Category: None
Event ID: 0
Date: 9/8/2006
Time: 11:05:38 AM
User: N/A
Description:
The description for Event ID ( 0 ) in Source ( .NET Runtime ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. The following information is part of the event: .NET Runtime version 1.1.4322.573- .NET Framework Initialization Error: C:\WINNT\Microsoft.NET\Framework\v1.1.4322\mscorwks.dll could not be loaded.
I have tried setting maximum num of threads and IOCompletion threads using SetMaxThreads method exposed by ICorThreadPool interface, but no help.
Task manager shows threads count 20 and IO Write- 5 for the windows service.
Could it be appdomain or threadpool? Any helping comment much appreaciated.
Thanks,

Is it possible to create a system.data.datatable or dataset from an excel worksheet that is obtained using interop.excel in C#?
The code is as following. As you can see, I can read/modify certain cell, but is it possible to convert the table to a System.data.datatable? Or at least print out the select range in the excelworksheet?
protected void OpenExcelSpreadSheet(string input)
{
Excel.Application excelApp = new Excel.ApplicationClass();
excelApp.Visible = false;
Excel.Workbook newWorkbook =
excelApp.Workbooks.Add(XlWBATemplate.xlWBATWorksheet);
// The following code opens an existing workbook
object Missing = System.Reflection.Missing.Value;
string workbookPath= "myFile.xls";
Excel.Workbook excelWorkbook =
excelApp.Workbooks.Open(workbookPath,Missing,Missing,Missing,
Missing,Missing,Missing,Missing,Missing,Missing,Missing,Missing,Missing,Missing,Missing);
// The following gets the Worksheets collection
Excel.Sheets excelSheets = excelWorkbook.Worksheets;
// The following gets Sheet1 for editing
string currentSheet = "Sheet1";
Excel.Worksheet excelWorksheet = (Excel.Worksheet)excelSheets.get_Item(currentSheet);
// The following gets cell A1 for editing
Excel.Range excelCell = (Excel.Range)excelWorksheet.get_Range("A1", "A1");
excelCell.Value2 = input;
Excel.Range excelTable = (Excel.Range)excelWorksheet.get_Range("A1", "A27");
int noOfRow = excelTable.Rows.Count;
int noOfColumn = excelTable.Columns.Count;
Response.Write("Table has " + noOfRow + " rows and " + noOfColumn + " columns.
");
}

Search this messageboard for 'eleventh' and'twelveth', there is a nice switch statement to deal with that, the rest will be easy.

Here is your code. I hope you like it;).
It consists of 3 methods. You call the ToLiteral() method and supply it with the string you want to parse. It will subsequently call the other two methods to retreive the literals and the segments names. Forgive me for the poor comment -never been good in commenting-. I included a button click even handler to show you how to test for output and how to use the ToLiteral() method.
private void TestButton_Click(object sender, EventArgs e)
{
MessageBox.Show("4\n" + ToLiterals("4"));
MessageBox.Show("57\n" + ToLiterals("57"));
MessageBox.Show("209\n" + ToLiterals("209"));
MessageBox.Show("8734\n" + ToLiterals("8734"));
MessageBox.Show("24567\n" + ToLiterals("24567"));
MessageBox.Show("973654\n" + ToLiterals("973654"));
MessageBox.Show("2315736\n" + ToLiterals("2315736"));
MessageBox.Show("27065154\n" + ToLiterals("27065154"));
MessageBox.Show("827464876\n" + ToLiterals("827464876"));
MessageBox.Show("1675376283\n" + ToLiterals("1675376283"));
}
private string ToLiterals(string Input)
{
String Output = "";
while (Input.Length > 0)
{
if (Input[0] == '0')
{
Input = Input.Remove(0, 1);
Output += "And ";
continue;
}
if (Input.Length % 3 != 2)
{
Output += ConvertChar(Input[0].ToString());
if (Input.Length % 3 == 0 && Input.Length > 2)
Output += "Hundred ";
else
Output += GetSegment(Input.Length / 3);
Input = Input.Remove(0, 1);
continue;
}
else
{
if (Input[0] == '1')
{
Output += ConvertChar(Input.Substring(0, 2));
}
else
{
Output += ConvertChar(Input[0] + "0");
Output += ConvertChar(Input[1].ToString());
}
Output += GetSegment(Input.Length / 3);
Input = Input.Remove(0, 2);
}
}
return Output;
}
private string GetSegment(int seg)
{
switch (seg)
{
case 1: { return "Thousand "; }
case 2: { return "Million "; }
case 3: { return "Billion "; }
case 4: { return "Trillion "; }
default: { return ""; }
}
}
private string ConvertChar(string ToConvert)
{
switch (ToConvert)
{
case "1": { return "One "; }
case "2": { return "Two "; }
case "3": { return "Three "; }
case "4": { return "Four "; }
case "5": { return "Five "; }
case "6": { return "Six "; }
case "7": { return "Seven "; }
case "8": { return "Eight "; }
case "9": { return "Nine "; }
case "10": { return "Ten "; }
case "11": { return "Eleven "; }
case "12": { return "Twelve "; }
case "13": { return "Thirteen "; }
case "14": { return "Fourteen "; }
case "15": { return "Fifteen "; }
case "16": { return "Sixteen "; }
case "17": { return "Seventeen "; }
case "18": { return "Eighteen "; }
case "19": { return "Nineteen "; }
case "20": { return "Twenty "; }
case "30": { return "Thirty "; }
case "40": { return "Fourty "; }
case "50": { return "Fifty "; }
case "60": { return "Sixty "; }
case "70": { return "Seventy "; }
case "80": { return "Eighty "; }
case "90": { return "Ninety "; }
default: { return ""; }
}
}
PS.
It took me about 35mins to write and test the code. It may need some adjustments, but it should give you a good start.

Thanks friend,
Your code is so logical and it took my two hrs. for understanding it. How your made the logic in just 35 min. You are a true programmer. The code meet all my requirements and I'll use it in my Data Base program "as it is" without any changing. So thanks and so nice of you.
God Bless You

Well a switch is a manual and less elegant way of doing this.
A preferred way is having all the digit equivalents in a string table, and then having the conjuntion operators in another one, and a mapping list for mapping the info. I will try to post some code on it, using the neural approach that i did 6 years back.

The System.Guid.NewGuid( ) method seems to have returned duplicate GUIDs, two days in a roll.
Is it possible? Is there any related .NET (1.0 or 1.1) bug reported for this problem?
