1> First,Check what kind of datatype you are using in database for this field.Make sure that the datatypes of the two in front end and back end are same.
2> If it is dateTime in the database then use
where dbtime between "+ #dtp1.value# +" AND "+ #dtp2.value# +" in the query string . instead of using
where dbtime between '" + dtp1.value + "' AND '" + dtp2.value + "'
i.e. You are trying to compare string type values. You should mot use
'"+ dtp1.value +"', instead you should use "+#dtp1.value#+".
also, you can use DateFormat function, if the format of the two dates are not same.
3>If you are using string type in database then you should not use dtp1.value.

it did not work her is more precise description
str="INSERT INTO tblHistoryLog(UserId,UserAction,TableName,ActionDate,TrDoneOn) VALUES('" + CheckValues.strUserId + "','NEW RECORD','USER TABLE','" + DateTime.Now + "','" + cmbTAUserId.Text + "')";
where ActionDate datatype if datetime.
i had inserted record in the table and inserted properly.
the query that uses the comparison
"SELECT * FROM tblHistoryLog WHERE (ActionDate BETWEEN #"+ dtpTo.Value +"# AND #"+ dtpFrom.Value +"#)"
but it gives the no result
i had tried to use this but it does not compile so i had to use above
"+ #dtpTo.Value# +" AND "+ #dtpFrom.Value# +"

It looks as if you are passing an SQL string. I am one of those freaks that insist on SP. Also you can make a command object with your query string and include parameters as in:
sqlString = "SELECT * FROM customer WHERE creationDate BETWEEN @startDate AND @endDate";
Then you can append parameters to the command and execute it.
(btw, don't quote me on this I am not on a machine with a devel environment write now or I would have posted compilable code)

Search for global hooks. There are some articles here on CP that cover this topic.

Hy,
I have a problemns. I want to read data from datagrid, but i have few problemns, that i can't.
Let me explain:
Datagrid looks : <asp:datagrid id="dgcam" style="Z-INDEX: 104; LEFT: 856px; POSITION: absolute; TOP: 288px" runat="server"
="" cellpadding="0" gridlines="None" showheader="False">
Function how fill this grid is:
private void cam()
{
string conn = ConfigurationSettings.AppSettings["conn"];
SqlConnection objConnection = new SqlConnection(conn);
DataSet ds = new DataSet();
string user = "select utilizator from furnizori where id_client =" + lbluser.Text;
string listcamion = "select count(id_camion) from add_camion join furnizori on (add_camion.id_user = furnizori.id_client)where id_user=" + lbluser.Text;
SqlDataAdapter da = new SqlDataAdapter(listcamion,conn);
da.Fill(ds, "add_camion");
da.Fill(ds, "furnizori");
dgcam.DataSource = ds;
dgcam.DataMember = "add_camion";
dgcam.DataBind();
try
{
objConnection.Open();
}
finally
{
if(objConnection.State == ConnectionState.Open)
{
objConnection.Close();
}
}
In Page Load i have this code, where i had problemns:
if(dgcam.Items != null)
{
listcamionuser();
}
else

Here i have problemns because i try to read data from grid. In grid count function works very good. In my page load i try to read grid who i fill this function cam(). This i don't knows how to put the cod(function is if(dgcam.Itemns != null) )
Pls help me.
Thanks for all

What I am wondering is if I can display a form within another forms field.
I have created a form that displays, updates, etc a database however I want that form to appear and be selectable from within another form.
I have created a clickable event that will show the form "outside" of my main form but what I want is for it to appear within an area of the main form.
I've searched everywhere but obviously my terminology is not yet good enough to match the experienced contributors to this fabulous vault 
If there is a tutorial that specifically covers what I want to do I would appreciate a pointer to it.
TIA

May be. I still don't know exactly what you want.
If you want to use your Form like it was a simple Control then just set its TopLevel property to false and add it to your other form via otherForm.Controls.Add(infoForm). Don't forget to set Location and Size properly.

Thanks for the response.
I'll play around with your suggestion as it seems to be what I do/did want.

Hello,
well, i have been checking this over and over again, but i am still unable to catch this exception:
System.Security.Principal.IdentityNotMappedException.
This exception is thrown when i use an incorrect authorizedGroup attribute
within my application config. Surely it's right that i get an exception when i specify a group that
doesn't exist but at least i should be able to catch it, shouldnt i?
try
{
RemotingConfiguration.Configure(".\\MyApp.exe.config", false);
}
catch (Exception)
{}
app.config
<channels>
<channel ref="ipc" portName="MyAppPort" authorizedGroup="IIS_WPG">
<serverProviders>
<<formatter ref="binary" typeFilterLevel="Full" />
</serverProviders>
</channel>
</channels>
However i assume that i can't catch this excpetion because RemotingConfiguration is running
in another (application?)context. Furthermore my application is doing fine. The only thing that bothers me is that
cannot catch this exception when a nonexistent group is specified.
If someone has an idea how to catch this exception, then please let me know.
I would really really appreciate it.
best regards Tobias

hi,
Hmm, i did this a thousand times but it doesn't point specifically to my application! Obviously RemotingConfiguration.Configure is running in a different thread but how to catch the exception in it?
e voila:
Unbehandelte Ausnahme: System.Security.Principal.IdentityNotMappedException: Man
che oder alle Identitätsverweise konnten nicht übersetzt werden.
bei System.Security.Principal.NTAccount.Translate(IdentityReferenceCollection
sourceAccounts, Type targetType, Boolean forceSuccess)
bei System.Security.Principal.NTAccount.Translate(Type targetType)
bei System.Runtime.Remoting.Channels.Ipc.IpcServerChannel.Listen()
bei System.Threading.ThreadHelper.ThreadStart_Context(Object state)
bei System.Threading.ExecutionContext.Run(ExecutionContext executionContext,
ContextCallback callback, Object state)
bei System.Threading.ThreadHelper.ThreadStart()
Further, this exception says that the system was unable to resolve the specified account. However i am fully aware of that and did intenionally use a wrong group. I just want to know
how to catch this security exception that is raised by the CLR.
regards Tobias

Nope, that is quite alright. As i said, there is nothing wrong neihter with the program nor with its configuration. I just need to know how i could catch a security exception that is raised during the remoting configuration. I mean my entire application works perfect, unless i specify a group that doesn't exist. It is quite logic that the remoting configuration fails when i specify a nonexistent group but why is it impossible to catch this security exception?
Anyway, thanks for your efforts.

I have a portal site that incorporates multiple web parts. One of the web parts is intended to pass a query string to a search application located in another area of the intranet. My problem is thus...The search application is written in standard asp and the portal site is asp.net 2.0/C#, how can I link the two up and pass the string.
Any help, suggestions, or possibly a push in the direction of a reference would be greatly appreciated.
Thanks in advance,
Cheers

You can pass the variable around between the two with the query string(term? I don't write asp.net)
ie: http://someWebAddress/someSite.asp?searchString=some%20really%20long%20search%20string;
or
ie: http://someWebAddress/anotherSite.aspx?searchResult=some%20really%20long%20result%20string;

Thanks for the tip, I'd forgotten about passing data this way, I'm still rather new to this , and I was kind of stuck in a brain-dead Friday funk.
I implemented the change and it is working well now, thanks.

You can use anything that you would normally use to pass information between pages, without storing the information on the server. Query string, form data, cookies.

Hi all,
I'm trying to write an application to deal with email forwarding (in the sense of being invisible to the end user) to a list of 100+ email accounts. I am using Indy.Sockets and a SMTP server provided by Fasthosts (standard mailbox).
I am having trouble getting the SMTP message to deliver to the addresses contained within the 'Resent-To' header ('Resent-From', 'Resent-Date' and 'Resent-Message-Id' are also being included). I'm having to add the 'Resent-To' header via the Indy.Sockets.Message.ExtraHeaders.Add() method as else the 'Resent-To' header seems to break-out into the main email, which results in an incorrectly formatted email (half of the 'Resent-To' addresses are shown in the body with the remaining headers).
Can anyone possibly offer any help? Or have successfully sent emails using a 'Resent-To' header?
Many kind regards,
Ben Whorwood

Hello!
I am a beginner in UI programming with C#. My problem: I have a ListBox on
a Form, that shall automatically update its content, when the data source
has changed.
I can fire the DataSourceChanged event in the data source class (which is
a derived ArrayList class) and also catch it in the Forms class. But
when I do there a ListBoxInstance.Update() or ...Refresh() ... or
Invalidate(), it has no effect at all. 
Maybe someone can give me a hint on what I did wrong?
Here is the interesting part of my source code:
Form1.cs:
private System.Windows.Forms.ListBox listBox1;<br />
private System.Windows.Forms.Button button1;<br />
<br />
private ItemList itemList = null;<br />
<br />
public Form1()<br />
{<br />
InitializeComponent();<br />
<br />
itemList = new ItemList();<br />
<br />
itemList.Add(new Item(1,"One"));<br />
itemList.Add(new Item(2,"Two"));<br />
itemList.Add(new Item(3,"Three"));<br />
<br />
listBox1.DataSource = itemList;<br />
listBox1.DisplayMember = "Desc";<br />
<br />
itemList.eventHandler<br />
+= new EventHandler(listBox1_DataSourceChanged);<br />
}<br />
<br />
private void listBox1_DataSourceChanged(<br />
object sender, System.EventArgs e)<br />
{<br />
Console.Out.WriteLine("DataSource changed 2");<br />
<br />
listBox1.Refresh();
Rectangle rect = new Rectangle(new Point(0,0),listBox1.Size);<br />
listBox1.Invalidate(rect,true);
listBox1.Update();
}
Item.cs:
public class Item<br />
{<br />
private int nr;<br />
private string name;<br />
<br />
public Item(int a, string b)<br />
{<br />
nr = a;<br />
name = b;<br />
}<br />
<br />
public string Desc { get { return "Nr:" + nr + " Name=" + name; } }<br />
}<br />
ItemList.cs:
public class ItemList : ArrayList<br />
{<br />
public EventHandler eventHandler = null;<br />
<br />
public ItemList()<br />
{<br />
}<br />
<br />
public void Remove(Item item)<br />
{<br />
Console.Out.WriteLine("Soll loeschen: " + item.Desc);<br />
base.Remove(item);<br />
FireDataChanged();<br />
}<br />
<br />
public void Add(Item item)<br />
{<br />
Console.Out.WriteLine("Soll adden: " + item.Desc);<br />
base.Add(item);<br />
FireDataChanged();<br />
}<br />
<br />
private void FireDataChanged()<br />
{<br />
<br />
if (eventHandler != null)<br />
{<br />
eventHandler(this,null);<br />
}<br />
}<br />
}
When I call the methods Add or Remove in ItemList, the event is fired,
I can see the Console.out.WriteLine-Message, but the ListBox is not
updated...
Thanks for help

DataSource to null and then reassigning it works.
listBox1.DataSource = null;
listBox1.DataSource = itemList;
