Hello everyone, If you have time, I need some suggestions.
I am making a mileage calculator, it is a project I thought up for me to gain some c# coding skills. Anyway, my dilemma is as follows.
I have a form with 6 combo boxes, one is a "START" and the other 5 are optional "ENDING" routes. Basically, someone can select "Indiana" on the first combo box and select "Akron" on one of the others, hit the calculate button and it will tell the mileage.
I have a DataTable set up with 3 columns "FROM|DEST|DIST" so it would be like
"Indiana" "Akron" 120
"Indiana" "Kalamazoo" 211
"Kalamazoo" "Phoenix" 1100
My problem is when i populate my first combo box with the "From" category, I get tons of duplicates, as there are many names in the from category that are the same. How Im adding data is below (Yes its being hardcoded, I dont know enough about databases to set one up yet)
xDt_List = new DataTable();<br />
<br />
xDt_List.Columns.Add("Start", typeof(string));<br />
xDt_List.Columns.Add("Dest", typeof(string));<br />
xDt_List.Columns.Add("Dist", typeof(short));<br />
<br />
DataRow xDr_Row = xDt_List.NewRow();<br />
<br />
xDr_Row["Start"] = "Indianapolis";<br />
xDr_Row["Dest"] = "Kalamazoo";<br />
xDr_Row["Dist"] = 211;<br />
xDt_List.Rows.Add(xDr_Row);<br />
<br />
xDr_Row = xDt_List.NewRow();
and so on and so forth...
Thank you for *any* suggestions on how I could make this a little more effecient ect.

DataTable.DefaultView.RowFilter = "Start DISTINCT";
ComboBox.DataSource = DataTable.DefaultView;

Hi. Im sort of a newbie in C# but i have a task for my graduation subject to create an application - a game or some sort of a quiz. Anyway, the application itself is not a problem. The problem occurs at the end of the game, because i had an idea that the player will get a diploma at the end of the game.
The diploma should look like this: The background is an old scipt (the game occurs around the 16th century) and on this script is some written text. There should also be an option to print out the players name.
So, please explain, if you can, if it's possible to edit an .doc file with some objects already present in the file (text, background) and add some text (the players name) in the middle of the page.
I know that printing some text, directly from a C# application is possible, but a file? and before printing, editing this file?
Is it complicated? If you could please add some code at your reply.
Thanks in advance,
Max
ps: sorry for my bad english.

I think the easiest way to do this with Word would be to use the VSTO[^].
However, a better approach might be to investigate the PrintDocument[^] and related classes[^] so you can roll your own solution.

Thank you for your fast answer. I will check those things out... but can anyone gime me an particular example? something small, just to see how it would look like. To read the file, edit the file and print it out.
Anyway, i will take a look myself at those links and try to find my own solution, but i doubt that it will come out soon  my deadline is in a month.
Bye,
Max

 Hi
I'm looking for a calendar that on which to add holidays etc onto, I've seen the month calendar and this is just what i am after with the exception that I would prefer to see a whole 12 months and not just 1 month at a time. Is there any way of doing this??
Thanks
Scott
I'm trying.......very trying

The normal way to do this (a la Outlook) is to display 12 of the calendars.
|

|

Thanks Pete,
That was my thinking, though with the standard monthcalendar it can be expanded to show the 12 months and i was just wondering if this could be applied with the added customisation

Hi guys,
this is the situation:
-i use a OpenFileDialog to get .doc files
-the file wil be saved into sql server table
-with a another button i can load that file from sql and open it with MS Word.
-the file wil also be saved in a directory on the disk. where to save? the path wil be read from config.xml that is located on the 'release' folder of the application(by loading of the form).
the problem:
- when u load the form for the first time, it works fine.
- bud the second time i dont know why bud the app trys to load the config.xml from the folder where i got my .doc file.
for example suppose that the last time i got a .doc from My Documents folder then i get the error:
Can't find C:\Documents and Settings\Me\My Documents\Config.xml
if from C:\ :
Can't find C:\Config.xml
bud the config.xml is located on release folder and this is the code to load the xml:
XmlDocument configfile = new XmlDocument();<br />
configfile.Load("Config.xml");
anyone a idea how to solve this?

Hi, if you use relative file paths, you rely on the value of the "current directory",
but this one may change, e.g. when switching directories in an Open/SaveFileDialog
(unless some properties prevent that).
It is best to use absolute paths to access application files such as config.
You can calculate the absolute path starting from system information such as the
current directory at app start, or Application.ExecutablePath

I'm sorry, but you seem to have got your keyboard a bit jammed up here. Perhaps you could keep this board operating in it's default English only setting. Anything else causes the hamsters to go into attack mode.

I presume your config file is in the same directory as the executable? Do you tell it this, or does it just "find" the file the first time?
The issue here is that you're relying on the config being in the applications "current" directory (which it is on startup, since the current directory is defaulted to the exe's folder)
When you use OpenFileDialog it changes the current directory to the location of the file you browsed to, meaning the config can't be found any more.
My suggestion would be to use System.IO.GetCurrentDirectory[^] on startup, and use this when loading the config.
e.g. something like:
m_ApplicationDirectory = System.IO.GetCurrentDirectory();
m_Configfilename = m_ApplicationDirectory + "Config.xml";
...
XmlDocument configfile = new XmlDocument();
configfile.Load( m_Configfilename );
