Well, theres the System.IO.DriveInfo class which gives a little information on a drive:
DriveInfo di = new DriveInfo(@"C:\");
Console.WriteLine(" Free Space: {0}MB", (di.AvailableFreeSpace/1048576));
Console.WriteLine(" Used Space: {0}MB",(di.TotalSize-di.AvailableFreeSpace)/1048576);
Console.WriteLine("Total Space: {0}MB",di.TotalSize/1048576);
1048576 is 1024*1024 because the properties return the number of bytes.
There's also FileInfo and DirectoryInfo classes, incase you ever want to use those too.

Hi,
I concur.
Except, if you mean 1024*1024, then why don't you write it like that, preserving optimal
readability? the compiler will do what is necessary and generate exactly the same code...

Yeah yeah, think your so clever don't you 
Thats just how i wrote it, then i thought i better mention where i pulled the number from. I guess it comes down to "I was to lazy to change the code"

The point is you don't need to first complicate the code and then add comments
to make a reader understand it; instead just keep it simple from the start!

you zoom an image by drawing it bigger - look at the DrawImage overloads on the Graphics class that let you specify the area to draw AND the area to draw it to.

So yeah, like Chris said, use the DrawImage overloads.
To zoom 40% you need to multiply the width of the image by 0.4, so something like DrawImage???(myImage, myImage.Width*0.4...);
I'm not sure on what the overloads actually are, or what parameters they take.
You will of course be needing to draw the image yourself, rather than using a pictureBox.

I am trying to get these 2 programs to work together.. one prevents autoplay in windows xp and the other detects the drive letters for newly inserted media.. The problem is, autoplay is in VB and the drive detector is in C#..
Currently, I only know a little C# and no VB.. and using online converters has not helped any, as there is always an error of some sort.. The main thing I'm trying to do, is convert one language to the other, and put them together into one program, with the end result of a program that stops autoplay while detecting new drives..
If somebody finds this file on this site.. tell me and i will change it..This is the program to prevent autoplay..
PreventAutoplay(VB)[^]
and this one detects the drive letters..
DriveDetector(C#)[^]

To convert VB.net to C# download sharp develop.
If it's VB6 you're SOL and will have to do a manual port.

Great program...works just as good as the website ive been using..but it has an issue after converting...a few errors that i am unable to fix..would somebody who knows what they are doing please help out a bit?..convert real quick and help me fix any errors it has?

No conversion program is perfect. IF you posted the code in question, perhaps we could help.

Is there a way to view the contents of a merge module through VS.NET or through some other free viewing tool?

Also the Files property in the setup project provides a popup that lists the files.

hi
i add a grid in my wpf window and load data from database.
now i want to bind grid control to dataTable, but i didn't found any DataSource property in Grid, how to bind it to display data ?
thanks
|
|

|

The Grid can't bind to a datasource. You can set the DataContext of the grid but then you have to create the layout etc and all the handlers for adding new rows etc.
If you are looking for a replacement for the DataGrid which is what I suspect you're after then Xceed give away a capable datagrid[^] for free which will do what you want.

Hello, I am new at C# and I am having difficulty 'starting' to write a program I am working on because I can't find any good resources on the WWW to answer my two questions.
Can anyone recommend some relief for me?
Here is what I have.
I want to save some test data is xml and generate a html report from the data. I seems like an xsl is the way to do this but I am not real sure how to read write xsl/xml and generate a report in html with Visual Studio 2008?
Does anyone know of any easy to understand examples, on how to do this.
I think it would also be useful to use linq to select values in the xml file and process them first.
Thanks for your help.

Try here, I started doing XML/XSLT reports and this has good info for beginners.

Hi there,
After reading msdn, looking for answers in google and testing a lot of different things, I gave up and now I'm here hoping for an answer.
The Problem:
I'm having a big problem trying to delete a row from a DataTable wich is related to its father. The exception I'm receiving is "Null Reference exception" (or something like that, my visual studio isn't in english)
The structure:
DataSet dsData contains:
DataTable dtbClients -> PrimaryKey: 'MotherAccount'
DataTable dtbAccounts -> PrimaryKey: 'ClientName'
DataTable dtbProducts -> PrimaryKey: 'CodeProduct'
Wich are related like this:
dtbClientes -> dtbAccounts (through column 'MotherAccount')
dtbAccounts -> dtbProducts (through column 'ClientName')
The data:
In this specific case, dtbClients has only 1 client wich has 1 account (in dtbAccounts) with no products.
What am I tried to do:
First I tried to remove the client directly because I though that the cascade constraint automatically created when we make a relation would take care of deleting the associated row in dtbAccounts. But that didn't happend.
The application threw and Null Referenec exception, and the stackTrace pointed to a function with 'Cascade' in its name.
Question 1): Is it possible to fix this exception and make c# delete everything associated to the removed client?
Well, with this exception I quited trying to delete the client directly and tried something else.
This time I'm removing the account related to the client first, this way when deleting the client there would be no problems since there are no rows related to it (I've no problems deleting clients with no accounts associated).
The problem:
It gives me the same Null Reference exception when trying to delete the account first! And it doesn't have any product related to it. My guess is that somehow the parent row(client) is related to it, so I can't delete it.
Question 2): How do I delete this account?
Can anyone help me with this ?
I hope I was clear enough.
Thanks in advance!
Oscar
