Well is there any other way to get the information I need?

In a WinForm if you create different BindingSources based on related tables in a DataSet, each time you create a new row in the child BindingSources the relationship key(s) value(s) are automatically entered in the child rows. This works really good.
My problem is I would like to be able to edit the key(s) in the master row.
If I do this then the child rows have no values created for the key(s) they take the value of null.
Is there a way to change the behaviour of the child BindingSources for them to take the new key(s) value(s)?
Is this even possible?
Thanks in advance for any ideas I am running out fast!

Hopefull that this helps someone in the future, all I had to do is EndEdit() on the master BindingSource!
A bit stupid from my part or was I

I'm thinking ahead, and wonder if anyone knows how a Type property is handled by its designers/typeconverters (if any)? What I'm hoping is that the designers/typeconverters for a Type property will allow entering the String class name of the type, and translate that to an underlying type field, f_MyType:
protected internal Type f_MyType = null;
public Type MyType
{
get
{
return f_MyType;
}
set
{
f_MyType = value;
}
}
TIA,
mike

Never tried it. I would suggest trying it real quick with a PropertyGrid. If it doesn't work, it shouldn't be too tough to write a custom type converter for that. I'm guessing it won't work, but shouldn't take much to test that.

Actually, I'd be tempted to write a type converter and maybe a UITypeEditor implementation that shows possible types to choose from.

Do you want to generate devanagri script numbers like: ०१२३४५६७८९
If Yes read on:
You can declare chars with the appropriate unicode and then do a ToString() to get the number in the desired format:
//Following will return the Devanagri Font '2'.
char HindiTwo = '\u0969';
HindiTwo.ToString();
The Unicode for the devanagri fonts 0 to 9 is '\u0967' to '\u096F'

thx alot,
that what i wanted ...and that was the only way to use unicode instead depend on the enviroment culture,but may be the only problem we cannot parse that unicode as number,
but anyway it will be appear as i want

I am making a custom host designer[^] and I am having a problem with my selection band updating. When I change the size of an item that is selected in my custom host designer fails to update the selection band. The control itself has a larger size but the selection band doesn't update to the larger size until I unselect the control and reselect it again.

Uhh.. wanna restate your question? I have no idea what you're asking.

Well menu item events are separate. One does not need Filename initialization. BTW, what is filename initialization?

hi Guys,
I am analysing the architecture for creating the following:
To load data from Visual Fox pro table into Sql table through C# Com+.
Steps I am after :
1. Create a method to read the data from Fox pro and convert it into an xml file.
2. Read the XML file and load into the table in Sql Server.
But I do not know which namespace to use to read data from Fox pro database and generate the xml file.
Can you guys please help???
Thanks
Sujit
happy coding!

In order to access FoxPro databases you have to use the OleDB data access classes. If you are familiar with the SQLClient namespace, all you need is to basically replace SQL with Ole in whenever you use anything like: SQLDBConnection --> OleDbConnection.
You do have to pay attention when you create the connection string for your database. The rest should be pretty straight forward if you have the odbc drivers installed properly for the fox pro database that you intend to use.
Good luck!

XML is not a very convenient intermediary data-format in this case.
You would find it simpler to use SQL-Server's SSIS (or DTS if you are using SQL-Server 2000). That would allow you to copy data from FoxPro directly into a SQL-Server table. Otherwise MS-Access linked-tables should be able to do the trick.
If you do need to copy the data programatically then use the .net ODBC or OLEDB classes to read FoxPro tables. You will then be able to link a DataReader object (from your FoxPro table) to an instance of the SqlBulkCopy[^] class to quickly copy data.
