function SetClientLabel(str)
{
document.getElementById("label1").innerText = str;
}

DataGridView - dragging multiple items with left mouse button

Currently, I can easily drag items between DGV's. If I select multiple items by holding the CTRL button while I click, and on the last item, I initiate the drag without letting up the mouse, I am able to drag multiple items.

However, if I select the last item, let up the mouse button, and then put it back down again to grab the items and drag them, the DGV selects the item that was under the mouse click. I realize this is the expected behavior; does anyone know a way to override it so that my items remain selected?

Now, I have a workaround that involves keeping track of the selected items myself, and if the mouse goes up and backdown and a drag begins, to re-select those items. But it's a little bit messy and I would really like another way to do it.

Any thoughts?

Issues with Converting IDataReader to DataSet

This is a 2005 project under 2.0
I am using Enterprise Library 2006
I am making a Select Call which returns an IDataReader.

I have checked the object after being populated and it seems to contain the information I need.

I go to convert it to a DataSet and it only shows the last item.

here is my Convert to DataSet code, I've tried numerous of examples found on the web, each one only returns the last record:

<br />
public static DataSet ConvertDataReadertoDataSet(IDataReader reader)<br />
{<br />
            DataSet ds = new DataSet();<br />
            DataTable schema;<br />
            DataTable data;<br />
            int i = 0;<br />
            DataRow dr;<br />
            DataColumn dc;<br />
            string columnName;<br />
            bool dun = false;<br />
            data = new DataTable();<br />
            schema = reader.GetSchemaTable();<br />
                  <br />
            do<br />
            {<br />
                if (schema != null)<br />
                {<br />
                    for (i = 0; i <= schema.Rows.Count - 1; i++)<br />
                    {<br />
                        dr = schema.Rows[i];<br />
                        columnName = dr["ColumnName"].ToString();<br />
                        if (data.Columns.Contains(columnName))<br />
                        {<br />
                            columnName = columnName + "_" + i.ToString();<br />
                        }<br />
                        if (columnName == "ID")<br />
                        {<br />
                            System.Type typeInt32 = System.Type.GetType("System.Int32");<br />
<br />
                            dc = new DataColumn(columnName, typeInt32);<br />
                        }<br />
                        else<br />
                        {<br />
                            System.Type typeString = System.Type.GetType("System.String");<br />
<br />
                            dc = new DataColumn(columnName, typeString);<br />
                        }<br />
                        <br />
                        <br />
                        data.Columns.Add(dc);<br />
                    }<br />
<br />
<br />
                    ds.Tables.Add(data);<br />
<br />
                    while (reader.Read())<br />
                    {<br />
                        dr = data.NewRow();<br />
                        for (i = 0; i <= reader.FieldCount - 1; i++)<br />
                        {<br />
                            dr[i] = reader.GetValue(i);<br />
                        }<br />
                        data.Rows.Add(dr);<br />
                    }<br />
                }<br />
                else<br />
                {<br />
                    dc = new DataColumn("RowsAffected");<br />
                    data.Columns.Add(dc);<br />
                    ds.Tables.Add(data);<br />
                    dr = data.NewRow();<br />
                    dr[0] = reader.RecordsAffected;<br />
                    data.Rows.Add(dr);<br />
                }<br />
<br />
            }while (reader.NextResult());<br />
<br />
            reader.Close();<br />
<br />
            return ds;<br />
        }

I f10'd through it and it seems to only be doing the 'do/while' once, the NextResult() is not going to the last record because it seems like its already at the last record.

Any suggestions or examples of another way of doing it would be great.

it needs to return a DataSet with multiple records.

NextResult moves the data reader on to the next result set, not the next row. Read moves the reader to the next row until it gets to the last row in the current result set.

Thank you for the reply. I found a way to work with the IDataReader that I am getting back so there is no need to convert it.

Appreciate the time on this though, enjoy your day.

How to create different versions/configurations in VS2005

frozenpondlife18-Dec-06 5:06

I would like to create different versions of a program, but I'm not sure how to achieve that in VS2005. I've looked at configurations and conditional compilation, but I haven't found anything that works yet.

Here's what I would like to do:

I need three versions of a program:

Version 1
=========
* Contains a user interface for analysing data
* Contains code and a user control for talking
to an electric motor, also contains a dll
that does the low level communication with
the electric motor.
This version would be installed on computers that have the electric motor attached.

Version 2
=========
* Contains only the user interface for analysing
data
This version would be installed on computers that don't have the electric motor installed. They would therefore also not have the dll and not need the user control for talking to the motor.

Version 3
=========
* Contains a simplified user interface for displaying results of the analysis.

What's the best way to achieve having these separate versions?

Thanks for your help.

Why not have several project in the same solution. Each sharing the source code for the items each version needs.

Thanks for your answer.

The reason, why I would like to avoid it is this: When I add a new source file to one of the projects, I have to add it to all projects, in case it is needed there. That is fine with a small project, but this one will over time get rather large and I want to keep maintenance of different versions to a minimum.

Conditional compilation is for small changes between different versions of the same assembly - e.g. DEBUG vs. RELEASE or excluding some features in a compact framework build.

You should create separate libraries for each module of your program and create three .exe files that use the libraries required for that version.

I am having a tabcontrol.Tab pages are added to it dynamically.Tab pages are type of "Form". On that form i am dragging a control.On the drag over event i get the e.X & e.Y position (screen coordinates).When i convert to Client coordinates i dont get the exact dropped location for control.

Like 1 big rectangle(tab page) with embedded small rectangle(Form).When control is dragged in small rectangle(Form) i dont get exact location.When i drag control to 0,0 position of small rectangle(Form) i get some other value(42,136).

Can anyone help me.Thanks in advance.

Yes. You can use the DataView class. Set the rowfilter = "field > " + date.toshortstring " + " and " + "field < " + date.toshortstring

Check you help files for the exact syntax, I'm just going from memory.
