I have a repeater with 2 nested repeaters inside to display multi-tier data.
The first Repeater contains Customer Information.
The Second Repeater contains Call Tracking Information
The Third Repeater contains Comments
The data currently displays like so:
Customer Info: Blah Blah Blah
Call Tracking Information: Blah
Comments about each Call Tracking Issue: Blah...
My query to obtain customer information looks like so:
"SELECT HSCTI.ItemID, HSCTI.Cust_Name, HSCTI.Region, HSCTI.Contact_Date, HSCTI.Reason, HSCTI.Status FROM HSCTI WHERE HSCTI.Status = 'Open'";
My ItemDataBound to my first Nested Repeater looks like:
public void Customers1_ItemDataBound(Object sender, RepeaterItemEventArgs e) <br />
{<br />
if ((e.Item.ItemType == ListItemType.Item) || (e.Item.ItemType == ListItemType.AlternatingItem)) <br />
{<br />
Repeater oRPT = (Repeater)e.Item.FindControl("Customers2");<br />
DataRowView oDrv = (System.Data.DataRowView)(e.Item.DataItem);<br />
oRPT.DataSource = oDrv.CreateChildView("<HSCTI>");<br />
oDrv.DataView.RowFilter = "HSCTI.Status = 'Open'";<br />
oRPT.DataSource = oDrv;<br />
oRPT.DataBind();<br />
}<br />
}
I keep getting an error indicating:
System.ArgumentException: This constraint cannot be enabled as not all values have corresponding parent values
Can someone tell me how to fix this?
Thank you.

I've updated a connectionString manually on IIS and restarted Web site,
but previously working INSERT is not working to the new data source.
New connectionString is okay (see details below).
I know I can have multiple connectionStrings, but don't know
how to select one of them on the fly.
I don't know how to handle this situation.
Any help will be very appreciated.
Thanks in advance!
Eugenio
DETAILS:
I'm running an ASP.NET Web Service (IIS 5.1).
Web service INSERTs a couple of records successfully into a DataSet
created using DataSet Wizard on VS2005 to a SQLEXPRESS on local machine.
I've the same database on a remote SQLSERVER (that I can access thru
MS SQLServer Mgmt Studio Express), and wanna INSERT data to it.
So I manually changed Web.config to the new connectionString on IIS and
restarted the Web site that I'm using. Data obviously did not go to the
old database, but it did not go to the new too! (although my code haven't
thrown any exception). Data has been lost.
Second turn, I configured the code to use an ODBC System DSN to the
old and okay database. Worked fine. Changed the DSN settings to the
remote database (connectionString remained the same) as restarted
Web site on ISS. The same behaviour got before: data was lost!

How can I prevent Cut'n'Paste between a couple of text boxes. An operator is required to enter a serial number twice to help prevent errors. The problem is they enter it once and then Cut'n'Paste.
|
|
|
|
|
Here's two ideas:
- add a keydown event to the text boxes and detect CTRL+C or CTRL+Insert (I'm a little foggy on it, but doesn't specifying it as "handled" prevent the control from processing the key? Something about that in MSDN library...)
- add an enter-event to the text boxes that clears out the clipboard
|
|
|
|
|
If you're using Visual Studio 2005, simply set the "ShortcutsEnabled" property of the TextBoxes to false.
Otherwise, please do not use suggestion 2. Well-behaved software citizens should not clear anything out of the clipboard unless requested by the user.

You're right (about being well-behaved), Office Lineman. Thanks for the tip!

Why do you make the user enter the number twice? The only time this behavior is needed is when it's a password, and the user can't visually verify that they're entering the right thing.

The operators enter a new serial number every two to three minutes all day long. Normally this is done with a barcode scanner but if the label is damaged they need to enter it with the keyboard. This serial number is written to EEPROM on the PCB under test. If they get it wrong, the board will have to go back through the programing cycle. The extra time, to enter it twice every so often, is worth avoiding the programing cycle. Additionally, the mistake might not be discovered until the board is installed in the final product. (Lots of wasted time...)

Hi folks
I'm trying to get the javascript variable in the HTML page loaded in WebBrowser control through IHTMLDocument2 interface. In VB6 it was simple: "WebBrowserInstance.Document.parentWindow.variableName".
But, I stuck in MSHTML interfaces.
Could somebody help me with that?
Thanks

You may get variable in this way :
IHTMLDocument2 document2 = (IHTMLDocument2)axWebBrowser1.Document;<br />
object variable= document2.parentWindow.GetType().InvokeMember ("variableName", <br />
BindingFlags.GetProperty, <br />
null, <br />
document2.parentWindow, <br />
new Object [] {});
The snippet below shows how to set the variable
document2.parentWindow.GetType().InvokeMember ("variableName", <br />
BindingFlags.SetProperty, <br />
null, <br />
document2.parentWindow, <br />
new Object [] {"New value"});

Does anybody know a good hashcode algorithm to generate unique codes?
What if you have two objects and their properties are equal? How would a hashcode be unique then?
Here, I am making an assumption that the hashcode is created using the properties of the control.
So I guess the real question is: Is there a way to generate a unique hashcode that doesn't rely on the properties of the object?
Thanks
Eric

Create a hashcode from the reference pointer.
---
b { font-weight: normal; }
|
|

Does the hashcode need to be unique/same across sessions? What're you using it for: uniqueness testing or sorting? If you don't need cross session consistancy or can save the code somehow, and are only using it for uniqueness testing: just give each object a guid.
|
|
|
|
|
If you need a unique hashcode that doesn't depend on the properties try the timestamp instead or you can use guid instead of calculating them on your own.
Greetings,
Ingo

Be aware that if comparison of instances return true, like in:
obj1.Equal(obj2) == true
then they must return the same hashcode.
obj1.Hahscode() == obj2.hashcode()
So, if you implement your own hashcode that is unique for every instance, make sure to override the Equal method to always return false.
If you don't do that, your class won't be usable in Arrays and Hashtables.

Hello,
Lets say I built my app on a machine that has Excel 2003 installed. So, the interop assembly created was built off of 2003.
Now, I have a few questions on what would happen if I ran the following code on a machine that had, lets say, both Excel 2000 and Excel 2003 installed.
using Microsoft.Office.Interop.Excel;
...
ApplicationClass app = new ApplicationClass();
MessageBox.Show(app.Version);
app.Quit();
...
1. If the user has both Excel 2000 and Excel 2003 installed, which one will be started? Will it always start the latest version?
2. If no Excel is installed at all, would app be null after the call to new ApplicationClass() or would that call not even be able to run?
Thanks.

I'm trying to compile a little C# program with the commandline csc compiler. I'm using the [DLLImport()] attribute, so I need the System.Runtime.InteropServices namespace, right? Problem is, csc wants to know what assembly it's from (there's no DLL named System.Runtime.InteropServices.dll). I need it for the /r: switch for csc.exe. Anyone?
|
|
|
|
|
Mscorlib.dll
---
b { font-weight: normal; }
|
|
|
|
|
I saw that one mentioned in the MSDN article for the attribute, but, when I use it, csc gives me the following error (the same as if I had not used it)...
[file and location]: error CS0246: The type or namespace name 'DLLImport' could not be found (are you missing a using directive or an assembly reference?)
Am I misspelling something?
By the way, I appreciate the help. Thank you!

Ok, I see what I did. I accidentally capitalized the two L's in "DLLImport". Now that I feel like a complete moron, I'll back out of here now. Thank you very much for the help! This place rocks!

Hi,
I'm working on a control contains two listviews which are arranged vertically.
I would like to synchronise them to make them appear like just one listview.
(they "view" are set to detail, columnStyle is set to "none" for one and to "Clickable" for the other one.)
I had allready synchronized the width changing of columns but I can find a way of managing the scrollbar.
I would like scrollbar doesn't appear in one listview and would be manage with the other one.
Is there anyone who can help me please ?

I'm using class Net.Socket to establish internet connection. Everything is OK, but I can't close the connection.
Methods .ShutDown(...) and .Close() do not help me - the connection is still alive, after calling these methods.
My code:
/////////////////////////////////////////////
_sock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
IPAddress address = hosts.AddressList[0];
IPEndPoint ipep = new IPEndPoint(address, port);
try
{
_sock.Connect(ipep);
}
catch(Exception sockex)//(SocketException sockex)
{
}
// CLOSING
_sock.Blocking = false;
_sock.Shutdown(SocketShutdown.Both);
_sock.Close();
|
|
|
|
|
I would think Close should. Did you try Disconnect?
Rather than swallowing exceptions, you might rather use a finally block:
try
{
_sock.Connect(...);
}
finally
{
_sock.Close();
}
