class WordPair
{
string [] rightpair = new string[] {"below\tunter", "blue\tgel", "cat\tgelb", "cat\tdie Katze",
"red\trot", "the dog\tder Hund", "to read\tlesen"};
}
}
At this stage, seeking help on creating a word pair object and calling a method for matching two different stringgs- one that produces a match and one that doesn't & be able to show the results of these matches.
Many thanks.

hi everyone,
well, I'm facing a strange probelm while I'm trying to populate a dataset table thru BackGroundWorker. I wanted this process to go into another thread as in the later future this could take some time.
I'm making a form in a windows application in C# 2.0 where the user selects a duration by selecting 2 dates and then presses the Go button and I
At first the code worked well but later it started to behave differently as there was simply no response on pressing the button. It turned out that the backgroundWorker was busy... and the application just hung up and crashed. Later I changed the code and populated the datatable in the usual manner.( in teh single threaded manner and it worked fine) but it doesnt satisfy me at all.
Please guve a few guidelines on this.
thanks for ur help

This is just a guess without seeing your code. When you click the button you probably need to check to see if the background worker process it already running. If it is you need to decide if you want to cancel it. Since you are using .net 2.0 perhaps you should just thing about using an asycn database call. If you look up SqlCommand.BeginExecuteReader you will find a nice example of how to do this.
Hope that helps.

well I was just calling the TableAdapters Fill method actually and now I'll on BeginExecuteReader. I' dont know if the tableAdapters fill method makes a asyncronous database call or not.
thanks for ur help

I have a simple common library project (XXX) with only an interface
with a string property A
public interface IXXX
{
string A{get;}
}
Than the Application A (for example a WinApp project called A)
references to XXX and implement IXXX, using [Serializable] Attribute
[Serializable]
public class XXX : IXXX
{
...
}
It has also a AObj "remotable" class:
public class AObj : MarshalByRefObject
{
IXXX[] GetXXX()
{
...
}
}
Another Application B needs to communicate with application A using Remoting;
B references XXX.dll because in its business logic, some class instance in B
makes a request to an instance of AObj (AObj.GetXXX()) using remoting and
receives from it an Array of IXXX; this call cause a SerializationException;
1)If the implementation XXX is inserted in the XXX project, no error occurs...
2)If I want to implement IXXX in the project A without problem, XXX
must extends MarshalByRefObject, but it's not what I want...
Some ideas?

Hi,
Im trying to print out a DataGridView. I bascily go through the data grid views columns and draw the columns name as a string. I then go through the data set and draw each row as a string.
The problem im having is i draw the columns/row posistion of the data grid views column width. Thus, if the column is only 10px wide but the text within that row is larger than the column, i draw the row and it over laps the next columns row.
eg:
Column A - ColumnB
aaaaaaaaaaabaaaaa
As you can see, column a's data is draw over column b's. I've thought of trimming the string and only drawing that, but since im printing the data, that kinda defeats the whole idea of printing something out.
Does anyone have any ideas how to over come this?
My only idea how to fix it would be to go through columns and check the width is big anough for the rows, and if not adjust the posistion and then draw the column names.
Regards,
Gareth.

Hi,
This is abit of a hack, but i found out if you did the below:
foreach (DataGridViewColumn col in dataGridView.Columns)<br />
{<br />
col.AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;<br />
}
It would expand the columns to display all the data within the cells.
Thus, problem solved.
Regards,
Gareth.

I have the following to serialize a simple string[] array:
<br />
string[] peteArray = new string[3] { "pete", "loves", "bananas" };<br />
string<br />
<br />
xmlPath = Application.StartupPath.ToString() + "\\" + "petesDiet.xml"; <br />
<br />
FileStream nameStream = new FileStream (xmlPath , FileMode.OpenOrCreate, FileAccess.ReadWrite); <br />
<br />
XmlSerializer nameSerializer = new XmlSerializer (peteArray.GetType()); <br />
nameSerializer.Serialize(nameStream, peteArray);<br />
<br />
nameStream.Close();<br />
<br />
It works fine. The problem comes in to try and de-serialize this - the Deserialize method doesn't seem to want to get a string[] object.
I have also tried the List<string> and using the CustomXMLSerializer (a class written by a guy on here) which seemed like it would have the solution but it doesn't work either! 
Any help would be much appreciated!

Do you get an exception when trying to deserialize?
|
|
|
|
|
No I can't even get to the running stage, I get a compiler error:
Error 1 Invalid expression term 'string' C:\D\CSharp\SysTrader\SysTrader\SysTrader\SysTraderForm.cs 688 71 SysTrader
The problem is when I try to initialize/create the Deserializer (in a different part of the program, or when the program has been restarted):
<br />
XmlSerializer xmlDeserializer = new XmlSerializer( string );<br />
XmlSerializer( Type type) takes type as an argument, and string[] produces an error too...
Thanks for your help!

It should be like this:
XmlSerializer xmlDeserializer = new XmlSerializer( typeof(string) );
|
|
|
|
|
You could try:
XmlSerializer xmlDeserializer = new XmlSerializer(typeof(string[]));

Gareth.

Well, yes. So it works now, right?

Hi Gerry,
While serializing and deserializing an array, list etc, I always find it better to create a wrapper class. That makes the things clearer and error free.
Like for your case create a class as below:
[Serializable]
class PeteArray
{
protected string[] arrPete;
//Function to set and get the values
}
Finally you can use this class Serialize and Deserialize.
