Do you want do to this in a GUI or just console?
One easy way to handle an XML File is the XMLDocument Class.
Another way is to try the XMLReader class.
Just see what you need.

Is the xml file valid for it selfe?
If so the XMLDocument Class is a little bit tricky, but it manage itselfs. With nodes oben close and the primitiv stuff. Another thing is that in runntime ther might occure symbols like "&" or other special symbols. For example you must wirite & in your xml file.
If this all is correct, and it doesn´t work please post the error message and the xml File or even the code.

Hi,
I want to filter the productID that starts with "MDF", so I use
bindingsource1.filter = "productID like 'MDF%'" (look like sql query), but it's not working.
Somebody could correct the code will be appreciated.
Thanks in advance.

It seem to be a solution or an answer.

Do you want a sql query for this?

if so then here it is

select fieldNames/* from tableName where productID like 'MDF%';

This would select all/several fields from the table name where the productID begins with MDF%

You can use connection/command/dataReader accordingly depending upon the database you are using.

It will be OK if I use sql query to filter the productID begins with MDF.
But, what I need is bindingsource1.filter = "productID like 'MDF%'" is correct or not ? I mean that "productID like 'MDF%'" string is correct or not. If not, How must I make it correct ?

It seem to be a solution or an answer.

Hi,
can I with CreateInstance create instance of form that requires parameters?

Example:

frmShopGood frmTemp = new frmShopGood(new DSBasis());

I tried this, but what can I do with parameter "new DSBasis()"
Form myForm = (Form)Activator.CreateInstance(Type.GetType(formName));

Thanks, Jure

Have you read the documentation for CreateInstance[^]?

Perhaps this[^] will help.

Something like this:

Type type = Type.GetType("MyNamespace.MyFormName");
object[] args = new object[1];
args[0] = new DSBasis();
Activator.CreateInstance(type, args);

maybe a bit of a hardcore solution, but you could instantiate your COM object in a separate application domain and when you don't need the COM object anymore drop the application domain, that should take care of the memory issue I think...

Have you tried this:

before you set your COM object to null?
