Erratic datagrid behaviour?

Hi,

I have a 12 column datagrid populated by an Oracle 8.1.7 table.

The 'grid is clickable so that more data can be viewed according to which ever row is clicked.

On any given row, if columns 0 through 9 are clicked, there is no problem. The same is true if column 11 on a row is clicked. The problem arises only if column 10 is clicked. The error message "Column does not belong to Table" is displayed.

All column names (Header Texts) are handled in a stored procedure, the custom datagrid style only handles column widths, anyone have any idea why column 10 would behave in such a way?

I need that column in the table as it stores image paths. If it is moved to a different position ie swap columns 5 and 10 around then the application crashes if "what was column 5, now column 10" is clicked. The same happens if I set the column width to 0. The column that occupies the same screen space causes a crash yet all other columns behave as expected.

Any ideas on why this is happening or possible solutions would be greatly appreciated.

I will post code samples if necessary

Thanks lots in advance

PropertyGrid and Null Default Values

Tristan Rhodes12-Apr-05 22:48

I've got a property grid i'm using to explore object Properties, which works fine.

However, I have a bug when an enumeration option is available and there is no default value, as the moment I click on the drop down box to select the new value, it throws an "Invalid Value of 0" error.

The enumeration in question has no Zero member, so I need a way to get around this if at all possible. Maybe by catching the error I would be able to select the item, but I don't know what where to place the exception handler.

Any thoughts?

Cheers

All enums can and are initialized to 0 (and hence the value is valid allways). Just try it.

enum Foo
{
  Bar = 10
}

Foo foo = 0;

Best would be to write a proper TypeConvertor to handle the default value.

Log4Net SMTP appender

Hi, I'm trying to send exception notification via log4net's SmtpAppender. But I'm having trouble deciphering the following error message:

System.Web.HttpException ... Cannot access "CDO.Message object" ...

Here's what my appender looks like, I think it's okay, but... just in case:
<appender name="SmtpAppender" type="log4net.Appender.SmtpAppender">
<to value=ccc@ccc.com" />
<from value="ccc@ccc.com" />
<subject value="ccc
<bufferSize value="512" />
<lossy value="true" />
<evaluator type="log4net.Core.LevelEvaluator">
<threshold value="WARN"/>
</evaluator>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%newline%date [%thread] %-5level %logger [%ndc] - %message%newline%newline%newline" />
</layout>
</appender>

I suspected that it's security problem with my virtual STMP server (IIS on XP Professional), so, first thing I did was to check:

> MMC console
> IIS
> Default Virtual SMTP Server (Right click and bring up "properties")
> "Access" tab
a. Authentication: Anonymous access permitted.
b. For "Connection" and "Relay", configure an empty list with "All except the list below"

But, this apparently didn't solve the problem. Any suggestion? Thanks in advance.

btw, I'm searching log4net mailing list archive: http://marc.theaimsgroup.com/?l=log4net-user&w=2&r=1&s=log4net+smtpappender+access+cdo.message&q=b

Hi all,
I am communicating with a serial port using overlapped I/O and I have a very strange problem.When I run my application,it's killed by the system in a random way when i communicate with the serial port.I can't find exact position that it's killed.It seem that the I/O is associated with the system. Anyone have same experience?I appreciate any reply.

C# Service No SocketException

Vadim Tabakman12-Apr-05 15:12

Hi all,

I am starting a C# Windows Service. In the Service class, I've added an object to the service class, and OnStart, I initialize this object which creates a socket listener. I use Asynchronous Sockets. So BeginAccept/EndAccept and BeginReceive/EndReceive is used.

My client app connects fine to the server and disconnects fine, but on the server end, the server doesn't recognize the client disconnection.

I receive a OnDataReceived message, which then triggers the EndReceive. I have a sample client-server application that does exactly the same thing, which I've cut-n-pasted from. In the sample, the EndReceive throws a SocketException with the error code 10054 (disconnection). But in my code, the EndReceive just returns 0 bytes received, and no exception is thrown.

Can anyone point me in the right direction?

Cheers,

I think that's the expected behavior, according to the MSDN documentation. " If the remote host shuts down the Socket connection with the Shutdown method, and all available data has been received, the EndReceive method will complete immediately and return zero bytes". You can therefore assume that if you get 0 bytes received in EndReceive, the remote client has disconnected.

Proble string and numeric values

Does anybody know how to search a word and read values from a file?
I used the method split to read values and separate words but the program doesn't give me the values of the float number. Even this method doesn't give me the correct number of words. It seems to me that it is taken spaces as a words. Any help will be appreciated.

Thank you in advance. Confused | :confused:

Ps. this is the code...
while(OpenSR.Peek()>=0)
{
string text =OpenSR.ReadLine();//Read line in the file
string [] Data=text.Split(new char[]{' ','\r','\n',',',':','='},10);
foreach(string s in Data)
{
Console.WriteLine("-{0}-", s);
}
Console.WriteLine(Data.Length);
}
