Hi
im trying to implement a calendar interface in my C# application but im not sure what the best way to draw the calendar is - i had a look at the form controls in visual C# 2005 and thought the datagridview might be a good start then populate it with events from an Xml file
Another possible solution would be google calender but i couldnt find any help with drawing google calender in C# application and thier tutorial was about adding and manipultaing events using .NET cliet libraries.
Does anyone have any ideas for this? i would appreciate any help
Cheers

The DateTimePicker control does it all for you presuming your working with WinForms and not WebForms.

Thanks for the reply, Rob. this is not what i im looking for though. i want to draw a calendar for a schedule and to have the days of the week displayed vertically and the time horizontally (similar to school timetable format) and then to populate this with shifts created in the program.

Personally I would handle the paint event for a panel and draw with the Graphics class, that way I can make it look anyway I want it to

A bit like Outlooks Calendar feature? Sorry, got the wrong end of the stick. Two routes to what you want - either get a 3rd party control which does that sort of thing or roll your own.
If you've not written a control like that before, its not a light undertaking!

what do you mean by third party control? something like Google calendar API
Cheers

You might want to have a look at:
Month Calendar[^]
and maybe:
Calendar DayView Control[^]
as well. There are demos and source code you can download and tweak should you wish.
Hope this helps, and good luck.

hi guys
i am having trouble formating my string text for my listbox.
this is what i am using
String.Format("{0,-15} \t {1,-50} \t {2,-20} \t", data1,data2,data3);
however due to the amount of space some text used up when many words are used the tab always goes out of place and end up making untidy
does anyone have a better alternative or a solution for this problem? pls assist

Try a fixed-size font (e.g. Courier) and fill it up with spaces instead of tabs
Doesn't look to cool, I know. If you want something better looking, try the DataGridView or the ListView.

Hi,
I need to plot the Square Wave form which have X and Y- Axis. The Wave will get Plot in to the graph(Windows Form) using c#.
Thanks
With Reg,

I think you need to be a bit more specific here? How is your wave represented? As a frequency, a wavelength, an array of samples?
Are you just trying to plot it to the screen?
Regards,
Rob Philpott.

Thanks for your quick response Rob!!!
Yes the wave can be drawn from the Array of values and the possible values are follows;
- Along the X-Axis (1,2,3,4,....) Y-Axis(A, B, C, D...)
- Based upon the bit values like 010101010 it should come up with UP(1)/DOWN(0) for A in Y-Axis.
It would be helpful if you shown me how to plot the value for Single Y-Axis 'A' Row.
Thanks,
Palanivel

Okidoke, you don't need to worry about the X-Axis, this just always increments. So you've got an array of booleans which alter (which is pointless really as we can draw a square wave by appreciating its repeating manner).
Graphics wise you'll want a windows forms application. Derive a class from Panel. In the derived classes override OnPaint.
You get a Graphics object given to you by that which allows you to draw lines and such things.
Create the loop and draw the lines. I can't offer much more help without knowing about things like frequency, scaling etc.
Regards,
Rob Philpott.

And what exactly have you tried so far?
Why is common sense not common?

A flexible charting library for .NET[^]
See this and try to use the function in it.
For example :
X = 0, 0, 1, 1, 2, 2, ...
Y = 0, 1, 1, 0, 0, 1, ...
That is a square wave.

Hi,
Using "AutoCompleteExtender" AJAX control, we can autocomplete the words, in web application.
How can I achieve the same functionality in Windows application?
Please guide me.

There are some AutoComplete[^] properties on the TextBox that you can use. An example on it's usage can be found here[^].
Good luck

Hi
I want to find a node from its text in an XML file with given string.
I'm taking this text from a textbox in my application and I want to find this node from XML file and
do some changes on it like changing childrens' texts or deleting the node and it's children from file.
any help :/ ?

There's usually two approaches to XML things like this, a streaming one which has a small memory footprint or the document approach where you load the whole xml into memory. The latter is easier if your xml is not too big.
(There's also a swanky new way using Linq2Xml which I know nothing about).
Something *like* :
XmlDocument doc = new XmlDocument();
doc.Load(<the file="">);
XmlNodeCollection nodes = doc.SelectNodes("//<element name="">");</element></the>
That will return you all the child elements with the name your looking for. You can iterate over them etc.
You'll need to brush up a bit on XPath to do it, but its easy enough once you've got your head around that.

Rob Philpott.

thanks for replies
I've changed my app a bit.
to be more precisive, the XML document is like:
<app>
<appname>application1</appname>
<action><arg>argument1</arg><ges>gesture1</ges></action>
</app>
<app>
<appname>application2</appname>
<action><arg>argument2</arg><ges>gesture2</ges></action>
</app>
..etc
I'm choosing a node from my treeview first, and the node in the treeview has the name with "title" node's inner text, (so arg and ges nodes are siblings for the title)
what I'm doing right now is;
XmlDocument doc = new XmlDocument();
doc.Load();
XmlNode editing = doc.SelectSingleNode(treeView1.SelectedNode.Text);
editing.NextSibling.InnerText = "changedText";
in fact, application gives "Object reference not set to an instance of an object." message pointing the "XmlNode editing = doc.blahblah" line
any further help?
edit: there's also a <title>NodeTitle1/2</> tag among arg and ges nodes which I forgot to add to xml example

The problem lies on you SelectSingleNode line.
You have to treat XPath statements a bit like directory structures. Unless there's a top level node of that name you won't find it.
You can use \\ to denote any (this node and all below). Try the below:
XmlNode editing = doc.SelectSingleNode(@"\\" +treeView1.SelectedNode.Text);
Regards,
Rob Philpott.

yeah this seems like the answer, but I couldn't understand the string structure
I've pasted your line in my code and it still gives an error:
XPathException was unhandled:
'\\Applications' has an invalid token.
:/
