Your DB is obviously broken. You can do a select to get the four rows, but if they have the same Id, then you have a bigger issue.

I had a look at your query and it seems fine. When you say that you have 4 rows for the same customer ID, do you mean that "CUSTOMERS"."CMF_ACCOUNT" has the same value?

If that's your key column (is it appears to be based on the query), I think your data is corrupted. If that's the key column of customers, it should be either primary key or unique key and there would be no duplicates.

When i run the query i found that there was a record with 4 different IMID, but the same transfer_id, i want to print those four records on to my form (aspx page)

Wendelius19-Jan-09 9:15

Based on your query, IMID is a column in TranferDetails and Tranfser_ID is the key column for Transfers, correct?
So if you have four rows in TransferDetails for a single transfer_ID, this query will result to four rows. Isn't this what you got when running the query?

I'm bit confused since if the situation described above is what you are experiencing, I don't see where the problem is. Or is the problem that your query actually returns four rows, but you're unable to show them simultaneously on aspx page?

I'm sorry but if the problem is in the aspx, that's something where I'm not able to help you.

I suggest that you try ASP.NET[^]-forum. I believe you would get good answers from there.

Print Multiple instances of the same form

I have a form that pulls data from database, and drops it in labels. Is there a way to print multiple instances of that form, one below the other to represent two records?

You can take screenshots by using the method that draws the form onto a graphics object, then build an image to print.

Problem with com creation in C#

I created an activex com object and would like to create an instance in a c# form. when adding the component with the wizard it creates a new instance with "new" end every C# exe gets its one inctance. I am looking for the equivalent C# whay to CoCreate: create the com object only if not exists, get the currantly active instance otherwise. I think the solution lies somware in interop services but failed to find a solution so far....

Re: Problem with com creation in C#

Not Active19-Jan-09 3:20

Not Active

19-Jan-09 3:20

C# doesn't have an equivalent to CoCreate, its all hidden behind the interop wrapper. You just have to create an instance of the object in question. If you want a single instance of this object then you need to use a Singleton pattern.

You probably want to use a regular expression to get the <a> tags in the page and then strip the href out of them.

CultureInfo and DateTime settings

Rick van Woudenberg19-Jan-09 2:33

Rick van Woudenberg

19-Jan-09 2:33

Gents,

I have the following problem that drives me insane. I've written a service that runs in the background. However, I can't get the DateTime format right. I must have tried everything to get it right, but to no avail. When the service starts or stops, it will tell me by writing to a log file. The output of the log file looks like this :

1/19/2009 1:48:40 PM Manager: Service Stopped<br />
1/19/2009 1:48:43 PM Manager: Service Started<br />
1/19/2009 2:17:05 PM Manager: Service Stopped<br />
1/19/2009 2:17:29 PM Manager: Service Started<br />
1/19/2009 2:18:02 PM Manager: Service Stopped<br />
1/19/2009 2:20:27 PM Manager: Service Started

Now .. When it writes to the logfile, it uses the above format for DateTime.Now , while I want to use "dd-mm-yyyy HH:mm:ss"
I set the regional setting in Control Panel as well as the Date and Time format. It shows up perfect in my system clock. It still spits out the above to the logfile. Then I tried the following in my code, so set it programmatically :

// The main entry point for the process
static void Main()
{
    //Set the culture
    CultureInfo newCulture = new CultureInfo("en-US", false);
    newCulture.DateTimeFormat.FullDateTimePattern = "dd-mm-yyyy HH:mm:ss";
    System.Threading.Thread.CurrentThread.CurrentCulture = newCulture;

    System.ServiceProcess.ServiceBase[] ServicesToRun;
    // More than one user Service may run within the same process. To add
    // another service to this process, change the following line to
    // create a second service object. For example,
    //
    // ServicesToRun = New System.ServiceProcess.ServiceBase[] {new WinService1(), new ySecondUserService()};
    //
    ServicesToRun = new System.ServiceProcess.ServiceBase[] { new RealTime() };
    System.ServiceProcess.ServiceBase.Run(ServicesToRun);
}

That didn't fix it .. still the same output.
When I put a MessageBox in between somewhere to let me show DateTime.Now.ToString(), it also comes back with 1/19/2009 2:20:27 PM. Some of the methods in the service report an invalid <code>DateTime</code> conversion when I try the following code :

DateTime time = Convert.ToDateTime("19-01-2009 13:12:56");

It drives me insane. Can please someone point me in the right direction ?

Kind regards,

You can try this line:
DateTime.Now.ToString("MMM dd,yy HH:mm:ss", CultureInfo.InvariantCulture)
I think it will solve your problem Cool | :cool:

Thank you for your feedback,

it does indeed fix half of my problem. I can get the date right in the logfile, however .. it will not fix the below calculation :

DateTime lastTime = Convert.ToDateTime(dt.Rows[lastRow]["date"].ToString());

Where the value in the DataTable is "19-01-2009 13:45:59", the error is :

1/19/2009 4:34:24 PM System.FormatException: String was not recognized as a valid DateTime.
   at System.DateTimeParse.Parse(String s, DateTimeFormatInfo dtfi, DateTimeStyles styles)
   at System.DateTime.Parse(String s, IFormatProvider provider)
   at System.Convert.ToDateTime(String value)
   at Loudnixx_RealTime.RealTimeRadar.ExceedTrackTime()
   at Loudnixx_RealTime.RealTimeRadar.ProcessString(String dat)
   at Loudnixx_RealTime.RealTimeRadar.Listen()

Somehow there has to be a way to set it globally throughout the program.

Can you point me in the right direction ?
