Hello,
This is what I'm trying to do.
Get the public folders out of each Exchange Server (that is visible through the Exchange System Manager). As the select * from exchange_PublicFolder only shows the folders at the highest level and not per storage group I looking at the ADSI approach.

this is the code so far. Parts have been commented out as I'm testing this new part with ADSI.

msExchPrivateMDB is the name to select the mailbox data. I'm sure there must be one for public folders as well ?

Any help would be greatly appreciated.

Hi,
You can write the code in KeyPress event. You get e.KeyChar. Check if it is Backspace and if yes execute some code. as simple as that !

Hi,

In my application i need to know when the monitor has changed state from stby to normal.

I know how to put it to stby using SendMessage, but what i need to know is when it wakes up (when the user uses the mouse or keyboard, for eg..).

Any help is appreciated.

XmlDataSource vs DataSource

Malcolm Smart16-Aug-06 23:37

16-Aug-06 23:37

I have unmanged DLL (legacy - can't touch it!) which returns an XML string. I want to bind this string to a datagrid....easy...or it should be. But I can't. I've isolated the problem below. To get the xml string into a dataset, I use a StringReader and use ReadXml. But when binding to Datagrid, it only shows the root node if I haven't pre bound the columns, or if I have, it complains the field isn't there (as it only exists in teh child nodes). I have saved the output from the Unmanaged DLL to an XML file which can be parsed, so the format is correct.

To test, I use two methods of populating the grid. The first one works fine, loading the XML file into an XMLDataSource. The second one doesn't - loading the XML file into a DataSource, via ReadXML. It is this second optoin I need to work, or some method of doing this where i can pass an XML string in.

works a treat, but I can't use as I have to receive from a string, not a file

XmlDataSource xds = new XmlDataSource();
xds.DataFile = ("d:/test.xml");

GridView1.DataSource = xds;
GridView1.DataBind();

doesn't work as it only seems to look at root node.

DataSet ds = new DataSet();

System.IO.StreamReader  str = new StreamReader("d:/test.xml") ;
StringReader rdr = new StringReader(str.ReadToEnd());

ds.ReadXml(rdr);//<-- this is the KEY bit as I need to load from a string
GridView1.DataSource = ds;
GridView1.DataBind();

Any ideas?

Regards

maybe you should use ReadXmlSchema().

Malcolm Smart17-Aug-06 1:39

The Dataset, read from an XML string contains multiple tables. The first table (the default) is the root node, the second table, contains the child nodes...so...changing the following line works a treat..

//GridView1.DataSource = ds; //defaults to Tables[0] which root node
GridView1.DataSource = ds.Tables[1];//child nodes - marvellous.

Can anyone tell me howa user can connect to the internt using my software. I want the user to be able to feed in the username and password and when Connect is clicked - the application connects using a network conmection on the computer. I would also be able to check wether authentication was successful and the connection state. Whioh library do i have to use. I tried googling it up but i couldnt find anything specific. I believe it is called "RAS" - am i correct? Thanks all.

Generics: T x = 5 fails [modified]

Dear gurus,

I have a generics question.

// T is either Int32 or Double
void fkt<T>( ref T someValue ) where T : IConvertible
{

Int32 i = 5;

someValue = i; <---- compiler error here
someValue = (T)i; <---- compiler error here

}

In both cases I get a type conversion error

How can I handle this? I know in advance, that T is only Int32 or Double.

Thanks for your help

Thank you ! ! !

You seem to be an absolute expert.

But two new questions arise: -))

1.
From where can I get such know-how? Is there any good book/paper available on such details?

2.
How can I restrict my Generic Type <t> to the basic datatypes as e.g.: char, int, double,..

fct<t>( T value ) where T: ...basic numeric types only ...

Kind regards

*blush* I googled it. I've only really used generics for typed containers, I was interested enough to know more that I was willing to spend a little time researching it and playing with a sample app.

I believe it is. This method should only work with int and double types only

private void CreateMethod<T>() where T : IComparable<int> , IComparable<double>, new()
        {
            T instance = new T();
            MessageBox.Show(instance.ToString());
        }

This won't compile as you put IComparable twice. However, one fixed, it seems to work with only numeric types. I had no idea you could put

int n = new int();

It seems kind of redundant to me.

Actually there was an error due to CP script. Sorry I have to remove the pre tag. Here is the correct code

private void CreateMethod<T>() where T : IComparable<int> , IComparable<double>, new()
{
T instance = new T();
MessageBox.Show(instance.ToString());
}

and why you call the new() redundant?? How would you declare your types in the method otherwise??
