Re: MS Access identifing primary key.

Hmm, I think you are using odbc or something similar to access the database.

One possibility to identify the primary key column could be to use Automation (take a look here http://support.microsoft.com/?scid=kb%3Ben-us%3B317114&x=18&y=5[^].

Then you could open the file using access and find the primary-key column.

Some SQL-DBS offers the possibility to get information abouot the structure by sql statements, but I don't know if access can do this.

Hope this helps you a bit.

Hi,

what kind of tables do you mean exactly? Database-Tables, DataTables in memory?

You can use GridView-Controls to display data from tables.

Please be more specific what you want to achieve, so that we can help you a bit better.

Okay, so what do you want to know exactly?

Something like this?

<br />
System.Data.DataTable table = new DataTable("MyTable");<br />
DataColumn column = new DataColumn("MyColumn");<br />
column.DataType = System.Type.GetType("System.String");<br />
table.Columns.Add(column);<br />
<br />
DataRow row = table.NewRow();<br />
row["MyColumn"] = "test";<br />
table.Rows.Add(row);<br />

Regards
Sebastian

P.S.: Please be so kind not to call me "dude".

SystemState - Windows Mobile Help

Hi all,

I'm just wondering if there is a way around this problem:

Basically, when an incoming call comes in and then it is missed, the event fires and grabs the last name and number of the caller. The problem being is that there are two lines added that are identical to the listbox.

SystemState MySysState = new SystemState(SystemProperty.PhoneMissedCall);
MySysState.Changed += new ChangeEventHandler(MySysState _Changed);

void MySysState Changed(object sender, ChangeEventArgs args)
{
ListBox1.Add(SystemState.PhoneLastIncomingCallerName.ToString() + ": " + ListBox1.Add(SystemState.PhoneLastIncomingCallerNumber.ToString());

}

MySysState is being declared in the form load, btw.

Could anyone point me in the right direction?

Thanks in advance.

Are you sure you need the nested ListBox1.Add()? Shouldn't the code look like:

void MySysState Changed(object sender, ChangeEventArgs args) 
{ 
ListBox1.Add(SystemState.PhoneLastIncomingCallerName.ToString() + ": "
 + SystemState.PhoneLastIncomingCallerNumber.ToString()); 
}

There is also one missing ")" in your code Smile | :)

Could it be that the event is being fired twice in quick succession? When I wrote a similar piece of code, I vaguely remember the event firing everytime the number of missed calls change. It fires when you get a missed call (missedcall count = 1) and fires when you go to the missed calls window (missedcall count = 0).

Hi,

I'm writing a game program using C# for a school project, similar to that of beatmania / djmax games. Anyone has any idea how to go about writing it? Or is there any similar references? Cos I don't seem to be able to find any online. Thanks!

Cheers,
Lun

Look for XNA tutorials - there are plenty of those out there
(XNA is Microsoft's managed wrapper around DirectX, and opens the door to the Xbox community games - i.e. if you get it good, you can get it released, and start earning money off it)

BitConverter?

float Float1= BitConverter.ToSingle( tempByte,0)

with temByte[0]= 0
temByte[1]= 0
temByte[2]= 160
temByte[3]= 127

Why after execution, i got Float1= NaN?

Thanks

Re: BitConverter?

Because that data is one of the codes that represent the value NaN.

Try for example { 0, 0, 128, 63 }.

Despite everything, the person most likely to be fooling you next is yourself.

1. Download the PDF specification from the Adobe site.
2. Read it thoroughly.
