You can. First you need to create so that there a frame capture or screen capture with a speed atleast 25 fps(This is for Europian PAL. USA uses almost 30 fps)and then send over network. Also you would need to make sure the client uses buffer for smoother streaming

Streaming video, over the network, to multiple users, with sound, at 25 FPS, and keeping it in synch ? You're insane.

DataBinding between a DataTable and a TextBox

Kit Fisto6-Oct-09 22:29

Hello. I have a question that i would like to ask all the codeproject members.
I have this cenario:

TextBox.DataBindings.Add("Text", DataTable, "Field", false, DataSourceUpdateMode.OnPropertyChanged)

A textbox is binded to a DataTable field. When i change the text on the textbox the cell from the datatable receives the new value, but the RowState of the current row doesn't changes to Modified, it keeps the Unchanged state. Only when i change to another row in the DataTable (the DataTable is binded to a DataGrdiView) that the RowState of that row is changed to Modified. The problem is that when i have only one row and the user saves the information, i use a batch update to save the changes in the DataTable, but as the row keeps the Unchanged State is doesn't gets to the update.
Is there any way to solve this?

Thanks in advance.

It is possible that the Row is still in Edit Mode.

When the user saves, does your code call EndEdit?

If this is a possibility, see How to: Commit In-Process Edits on Data-Bound Controls Before Saving Data[^] on MSDN.

Right before you call update on the data set, call this:

private void CommitChanges(DataSet ds)
{
    foreach (DataTable dt in ds.Tables)
    {
        foreach (DataRow dr in ds.Tables)
        {
            dr.EndEdit();
        }
    }
}

Or, you could first subscribe to the ColumnChanged event on the table

dt.ColumnChanged += new DataColumnChangeEventHandler(dt_ColumnChanged);

then in the event do this:

static void dt_ColumnChanged(object sender, DataColumnChangeEventArgs e)
{
    e.Row.EndEdit();
}

Everything makes sense in someone's mind

The same way you'd call a stored proc. Use ExecuteScalar if your function has a single return value.

You would take a screenshot of the actual desktop, and then chop it based on the box the user drags.

Are you sure it's not enumerating the processes on the system and then capturing their windows?

How to set an item in a object's property(of array type) using Reflection

Hi All,

I have a class named "C1" which has a property name "P1", which is declared as below in class.

Class C1
{
...
Account1[] P1;// Here Account1 is another class/type
...
}

Now i have created an object of "C1" using reflection as below.

// object
Type objTempType = Type.GetType("C1");
object objTempObject = Activator.CreateInstance(objTempType);

Now i want to set value of first item in "P1" property(An array property) of objTempObject using reflection, which i can do without reflection as per below.

objTempType.P1[0].SomeFieldinAccount1Class = SomeObjectOrValue;

Could any one of you please give me some direction on how is that possible.

I checked all the possible ways do it using property/reflection related classes in C#, also searched many sites and forums to get answer but without any success...

Hi
Before you can set the SomeFieldinAccount1Class property/field value you need to intialize / create the element at position 0

objTempType.P1[0] = new Account1();

Hello nissims,

Thanks for your reply.

i have already created the first item in P1[0](before i try setvalue thing), I just didn't want to make my post a more lengthier one, so made the code hide.

You can use the Array class when operating on array properties with reflection.

Using only refection, what you want to achieve is done like this:

Type objTempType = Type.GetType("C1");
object objTempObject = Activator.CreateInstance(objTempType);

PropertyInfo p1Property = objTempType.GetProperty("P1");
Array p1ArrayValue = p1Property.GetValue(objTempObject, null) as Array;

Type itemType = p1ArrayValue.GetType().GetElementType();
object itemValue = p1ArrayValue.GetValue(0);

PropertyInfo someFieldProperty = itemType.GetProperty("SomeFieldinAccount1Class");
someFieldProperty.SetValue(itemValue, SomeObjectOrValue, null);
