Yes, thats the whole idea.
You get a Mouse Down, and start tracking the mouse. You can then follow (and select) all the images you wish until you get the MouseUp. The only other way to do the multiple selections is via Control + MouseDown, or Shift and MouseDown - which does not sound like what you want.
I seriously would not consider breakpointing MouseMove!
As a sugestion, set up a form with your images in it, and use Spy++ to examine the mouse messages as you perform the actions you want to do the selections. This should give you a good idea of the message flow you can expect, and you can then see how to handle them.

It sounds like what you are trying to do may be accomplished better by using the same techniques as for drag-n-drop. Your current approach will only trigger a single mouse-down event so what you will need to do is get the "point" (x,y) position during the mouse down, track the mouse move event and get the "point" (x,y) position at the time of the mouse-up event. Of course this requires you to determine which picture boxes fall within the selection buy comparing their locations.

Good Day All
I have the Following Code in my DAL
public SqlDataReader Get_Staff_Cycles_internal(String DB)
{
SqlDataReader rd = null;
strcon = GetConnectionString(DB);
con = new SqlConnection(strcon);
cmdselect = new SqlCommand();
cmdselect.CommandType = CommandType.StoredProcedure;
cmdselect.CommandText = "[dbo].[sp_Get_Staff_Cycles_internal]";
cmdselect.CommandTimeout = 0;
cmdselect.Connection = con;
try
{
con.Open();
rd = cmdselect.ExecuteReader(CommandBehavior.CloseConnection);
}
catch (SqlException)
{
throw;
}
finally
{
if (con != null)
{
con.Close();
}
}
return rd;
}
and Am using this code Like this In BLL
public SqlDataReader Get_Staff_Cycles(int ACTIVITY_ID, String DB)
{
DAL.DAL obj = new DAL.DAL();
SqlDataReader rd = null;
try
{
obj.Get_Staff_Cycles(ACTIVITY_ID, DB);
rd = obj.Get_Staff_Cycles_internal(DB);
}
catch (SqlException)
{
throw;
}
finally
{
obj = null;
}
return rd;
}
And am Calling it like this in PL(Presentation Layer)
private void Bind_Grid_For_Staff()
{
SqlDataReader rd = null;
BLL.BLL obj = new BLL.BLL();
try
{
if (Convert.ToString(Session["Selected_ID_Bind"]).Length > 6)
{
String Activityid = Convert.ToString(Session["Selected_ID_Bind"]);
if (Activityid != null || Activityid != "")
{
ArrayList Final_String = (ArrayList)Fixed_String_Multi(Activityid);
for (int i = 0; i < Final_String.Count; i++)
{
rd = obj.Get_Staff_Cycles(Convert.ToInt32(Final_String[i]), Convert.ToString(Session["ActiveDatabase"]));
}
if (rd != null)
{
while (rd.Read())
{
Gridstaff.DataSourceID = null;
Gridstaff.DataSource = rd;
Gridstaff.DataBind();
}
}
}
else
{
lblGridStaff.Text = "Could not Bind StaffGrid";
lblGridStaff.ForeColor = System.Drawing.Color.Red;
}
}
else
{
if (Convert.ToString(Session["Selected_ID_Bind"]) != null)
{
String Activityid = Convert.ToString(Session["Selected_ID_Bind"]);
if (Activityid != null || Activityid != "")
{
ArrayList Final_String = (Fixed_String(Activityid));
for (int d = 0; d < Final_String.Count; d++)
{
rd = obj.Get_Staff_Cycles(Convert.ToInt32(Final_String[d]), Convert.ToString(Session["ActiveDatabase"]));
}
if (rd != null)
{
Gridstaff.DataSource = rd;
Gridstaff.DataBind();
rd.Close();
}
}
else
{
lblGridStaff.Text = "Could not Bind StaffGrid";
lblGridStaff.ForeColor = System.Drawing.Color.Red;
}
}
else
{
Response.Redirect("SubjectStaff.aspx", false);
}
}
}
catch (ApplicationException e)
{
lblStatus.Text = e.Message.ToString();
}
}
i get an Error
Invalid attempt to call MetaData when reader is closed.
and its Poiting to the part that Binds the gridview here
Gridstaff.DataBind();
Thank you

Never, ever, ever try to bind an open datareader to a form, while the data reader is open the connection is locked.
Change from using datareader to datatable (uses a datareader under the hood) and it should all fall into place
Vuyiswa Maseko wrote: rd = cmdselect.ExecuteReader(CommandBehavior.CloseConnection);
I use this to return a table
SqlCommand oCmd = new SqlCommand();<br />
SqlDataAdapter oDA = new SqlDataAdapter();<br />
DataSet oDS = new DataSet();<br />
<br />
oCmd = CreateCommand(sProcedureName, arParam);<br />
<br />
oDA.SelectCommand = oCmd;<br />
oDA.Fill(oDS);<br />
<br />
<br />
mvTimeOut = _TimeOut;<br />
return oDS.Tables[0];<br />

Thanks Mycroft
Am trying to avoid using Datatable because of Performance. That is why i wanted to use a datareader.
Thanks

You must have an extroadinary amount of throughput to be able to detect the performance difference between reader and table or is it theoretical peformance difference.

So presumably another process is writing the file to the location, I am assuming you are trying to read it while some other process is still writing. Build in a delay for x seconds the first time you see the file and try again.

Hi,
I get the same error. I'm using a FileInfo object with a file name passed to the constructor upon creating the FileInfo object. I check if the file exist and if so I delete it and recreat it. Al works fine first time but when I click on the button again to do the same functionality over again I get same error mentioned. The is NO close method on the FileInfo object nor Dispose. I tried the Refresh() in desprate attemps but still error. Please see a snipplet below:
private void button2_Click(object sender, EventArgs e)
{
FileInfo fileInfo = new FileInfo(label2.Text + ".TMP");
if (fileInfo.Exists)
{
fileInfo.Delete();
}
fileInfo.Create();
int y = 0;
}

Hi Guys,
Mine was a dumbass developer faullt...well... din't realy knew once you create the file the creat method returns a stream  so yea just changed my line of code abit
FileStream stream = fileInfo.Create();
stream.Close()
Hope your problem is as simple as this...

Can we Update records in the table using SqlBulkCopy
|
|
|
|
|
No
Unless you bulkcopy into another table and execute a proc to do the update

Hello! 
I know how to do extension methods and I'm pretty sure I could teach my cat to do them too, but is there a way to somehow have one external method, and use it in several different projects simply by referencing the file it is contained in? Would this be done in a class file ir DLL file? I'm pretty new to this stuff, and would appreciate any suggestions. Thanks for readin'.
Regards,
Jase
private void Yay()
{
DirectoryInfo Di = new DirectoryInfo("J:\\");
FileInfo[] Files = Di.GetFiles("*.*");
foreach( FileInfo file in Files )
{
// Do something constructive.
}
}

Either way could work, to be honest. It's up to you whether you want the overhead of an extra DLL, or you're happy having the code included as a link.
