Indeed. Why is that, even when dateFrom is created earlier than dateTo?

/edit:

Looks like Controls.Add() is called with dateTo first, then dateFrom next.
I rearranged them, I hope it's fixed now.

Re: DateTime diff weirdness

The Ticks property holds the actual raw value that represents the date. A DateTime object in .NET always contains a full date/time value, which includes fractional seconds. Depending on how you are initializing the variables, you are most likely hitting differences in a portion of the time smaller than what you are actually visibly seeing.

Try initializing them using the full constructor, which specifies the full date and time values, or setting one equal to the other.

Maybe they differs in milliseconds (or even ticks). I suggest you to initialise a TimeSpan var with the difference of the two DateTimePickervalues and then check the amount of the difference (for instance you may consider equivalent two dates having different hours).

Problem appending XML elements

I have the following code which is supposed to append two elements, each having string content, to the previous element. The problem is that only the second string is added to the xml file!

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(sFile);

XmlElement elem = xmlDoc.CreateElement("card");

XmlAttribute attr = xmlDoc.CreateAttribute("number");
attr.Value = iCardNo.ToString();
elem.Attributes.Append(attr);

elem.InnerXml = "<front></front>";
XmlText textNode = xmlDoc.CreateTextNode(sCardFront);
elem.FirstChild.AppendChild(textNode);

elem.InnerXml = "<back></back>";
textNode = xmlDoc.CreateTextNode(sCardBack);
elem.LastChild.AppendChild(textNode);

xmlDoc.DocumentElement.AppendChild(elem);

xmlDoc.Save(sFile);

Only the second element is appended!

This line overwrites all content of the element. To be consistent you should use CreateElement and AppendChild to add the front and back elements.

Ok it's working better. However, the card element has no closing element tag. The card element is

<card number="1" />

rather than

<card number="1">
</card>

Here's the code:

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(sFile);

XmlElement rootElem = xmlDoc.CreateElement("card");
XmlAttribute attr = xmlDoc.CreateAttribute("number");
attr.Value = iNewIndex.ToString();
rootElem.Attributes.Append(attr);
xmlDoc.DocumentElement.AppendChild(rootElem);

XmlElement frontElem = xmlDoc.CreateElement("front");
XmlText text1 = xmlDoc.CreateTextNode(sCardFront);
xmlDoc.DocumentElement.AppendChild(frontElem);
xmlDoc.DocumentElement.LastChild.AppendChild(text1);

XmlElement backElem = xmlDoc.CreateElement("back");
XmlText text2 = xmlDoc.CreateTextNode(sCardBack);
xmlDoc.DocumentElement.AppendChild(backElem);
xmlDoc.DocumentElement.LastChild.AppendChild(text2);

xmlDoc.Save(sFile);

Thanks for the help!

This is perfectly valid in XML.

That's true. But I would like the two innner tags to be wrapped in the card tags.

<card number="1">
  <front>Some content</front>
  <back>Some content</back>
</card>

Hello, I've got a problem, how to create synchronized RIchTextBoxes (Controls, not Forms) in C#, .NET 3.0. There are total 3 rtboxes and I want them to be synchronized together. The problem is, that ther's no scroll event raised by the RichTextBox, the only thing, I've found, is
ExtentHeight, ExtentWidth, HorizontalOffset, VerticalOffset, ViewportHeight, ViewportWidth.

I've also tried to create an extra Scrollbar and use it for controlling the rtboxes, but it doesn't worked, somehow.

Please help, thank's a lot Smile | :)

Hi!

I want to do the following:

All seconds I want to delete an existing picture and do Graphics.DrawImage with a new picture. So my problem is: I can't delet the old picture from Graphics and so no changes are shown on my screen.
Does anybody know help?

thanks

I have no idea what you mean by 'delete the old picture from Graphics'. Calling Invalidate() forces a paint event, which will redraw the form.

How are you drawing/storing the image ?
