How to change text of buttons on MessageBox - C# Discussion Boards

Hi. I'm using the "File.Move" method in the System.IO namespace. When I start my program and call this method it executes no problem. The second time I call it I am getting and error message saying "Exception: The process cannot access the file ... because it is being used by another process".

When I close the program and run it again the method runs fine, again for the first time.

I would think the connection is just not closing for some reason. Does anyone know how I can fix this?

Well, you could try calling dispose() on your object to see if it would help. My guess is your problem is somewhere else. Are you using any FileStreams ? You definately need to close those by explicitly calling Close() on them. Post some more code if you can...

Not enough information. Move what file? Is your application writing it? Are you holding it open? Where does this file come from that your trying to move?

The problem is obvious - "being used by another process". This means that you can't move a file that is open for reading and/or writing. So what has the file open?

Data Adapter Column Limits?

My data adapter wizard will not configure a table with more than 100 columns. Is there a way to get it to do so? I have tried to manually configure bt I get a syntax error message when I exceed 100 columns. Thanks

Do you have the ability to cut down on the number of columns in your table? 100 columns in a single table isn't a good idea.

I could spit the table into smaller related tables but i will still need to update 118 columns at the same time. It appears that 100 is the limit for a data adapter.

Split the table into smaller tables and use a DataSet with multiple tables. You won't have any issues with that approach.

The possible text on a messagebox is set via an enum. If that doesn't suit, you need to write your own.

Firstly, It appears that your post contains HTML or XML. You should either escape this by replacing the < with < or by checking the "Do not treat <'s as HTML tags" below the post's edit box.

Secondly, can you please write full words - I am having difficulty parsing your sentences. For example: pl --> please; soln --> solution

How to determine if Object obj is a collection or not?

Given an object, how do I determine of the object is a collection of objects or a single object ?

- Thanks

There is no hard and fast rule and it depends on what you consider to be a collection. However, you can tell if an object is enumerable (i.e. you can use it in a foreach statement) because it will implement the IEnumerable interface. Although, IIRC, the C# compiler just looks for a GetEnumerator() method.

To do that programmatically, just check for the IEnumerable interface.

bool IsCollection(object b)<br />
{<br />
   return b is IEnumerable;<br />
}<br />

Looking for a better way to build a Dataset

Adam °Wimsatt2-Mar-05 5:03

I have a situation where I need to load 8 key value pairs into a DataSet manually.

The data looks like this:

Mon -- 123.4
Tues -- 232.1
Wed -- 187.4
...
EOW -- 923.6

I have to get these values into a DataSet. Is there a better (less lines of code) way to load it into a DataSet than to create a DataTable manually?

This is what I have so far:

<br />
DataSet ds = new DataSet();   <br />
DataTable dt = new DataTable("MCDVals");<br />
dt.Columns.Add("Legend", typeof(string) );<br />
dt.Columns.Add("Value", typeof(double) );<br />
<br />
DataRow dr = dt.NewRow();<br />
dr("Legend") = "Monday";<br />
dr("Value") = 123.4;<br />
dt.Rows.Add(dr);<br />
<br />
// ... above block repeats another 7 times for the other values<br />
<br />
ds.Tables.Add(dt);<br />

Thanks,
Adam

Just load it into the XML , it is very simple. and you have lots of methods to write , save ...xml using datasets
