Reporting Services: Draw rectangle on chart's plot area

17-Mar-08 20:48

You haven't explained why a rank of 3 should be returned for 15% However I assume this is because 15% is between 10 and 20%. In this case, you shoul use the BETWEEN clause in your query.

Why are you storing percentages in varchar fields? They are numbers, so they should be stored in numeric fields. You will run into problems every time you want to do numeric comparisons because you will need to case your varchar values to numbers.

Hello..

I've got an InvalidOperationException: invalid Value vor the OracleObjectMappingAttribute nNR

Could NET have a problem with casting NUMBER to int? Or have i to do something
special, because I'm using a OUT-only Parameter?

Here are my code:

PLSQL:
-------------
create type TESTOBJ as OBJECT (
nNR NUMBER;
sTEXT VARCHAR2(20);
)

create testproc(p_testobj OUT TESTOBJ)
as
v_testobj TESTOBJ := TESTOBJ(1,'Test');
begin
p_testobj := v_testobj;
end;

C# the Mapped OBj:
-------------------------------
public class OracleXTBQueueObj : IOracleCustomType
{

private int nr;

[OracleObjectMappingAttribute("nNR")]
public int NR {
get { return nr; }
set { nr = value; }
}

private string tEXT;

[OracleObjectMappingAttribute("sTEXT")]
public string TEXT
{
get { return tEXT; }
set { tEXT = value; }
}

public virtual void FromCustomObject(OracleConnection con, IntPtr pUdt)
{
OracleUdt.SetValue(con, pUdt, "nNR", this.NR);
OracleUdt.SetValue(con, pUdt, "sTEXT", this.TEXT);
}

public virtual void ToCustomObject(OracleConnection con, IntPtr pUdt)
{
this.NR = ((int)(OracleUdt.GetValue(con, pUdt, "nNR")));
this.TEXT = ((string)(OracleUdt.GetValue(con, pUdt, "sTEXT")));
}
}

C# the Factory:
-------------------------------
[OracleCustomTypeMappingAttribute("USR.TESTOBJ")]
public class OracleXTBQueueObjFactory : IOracleCustomTypeFactory
{
public IOracleCustomType CreateObject()
{
OracleXTBQueueObj obj = new OracleXTBQueueObj();
return obj;
}
}

C# the function, callin the PROCEDURE:
------------------------------------------------------------
public static void GetOO(OracleConnection conn)
{
OracleCommand cmd = new OracleCommand("UDT_TESTPROC", conn);
cmd.CommandType = System.Data.CommandType.StoredProcedure;

OracleParameter paramDaten = new OracleParameter("p_testobj", OracleDbType.Object, ParameterDirection.Output);
paramDaten.UdtTypeName = "USR.TESTOBJ";
cmd.Parameters.Add(paramDaten);

try { cmd.ExecuteNonQuery(); }
catch (Exception ex) //InvalidOperationException
{
Console.Out.WriteLine(ex.Message)
}
Console.In.ReadLine();
paramDaten.Value.ToString();

}

I am working on a report which requires me to draw two polygons (rectangles) on a scatter chart to visually indicate "good" and "bad" ranges of plotted data. Is there a way to do this out-of-the-box?

Otherwise, if I must create a custom report item, how do I draw on the chart surface? I have looked at the following articles on Custom Report Items, but when I open the sample solutions I can't put the custom report items on the chart surface.

Do I have to create a custom report item which inherits from a chart control? If so, does anyone have any reference samples?

I have used the Dundas Chart for Reporting Services component to solve a similar problem, i.e. applying custom rendering to a Reporting Services chart. The Dundas Chart component exposes a PostPaint event which allows a developer to draw onto the chart surface area. Code is written against the chart control in C#.

The component isn't cheap, but it does open up new possibilities for charting with Reporting Services. It is especially useful when you need to apply your own customizations to a chart that don't come out of the box.

Thanks, that's one of the solutions I am looking at. However, this is the only requirement I have (so far) which doesn't come out of the box. So I'm not sure if I can get approval to purchase a license just so I can draw a couple rectangles. Of course it's beginning to look like my time to develop it myself will cost a lot more than just to license a 3rd party charting solution.

Something else I have tried in the past is writing a custom assembly in .NET that internally renders a Reporting Services chart. This can be achieved by using the web services that Reporting Services exposes to programmicically render a report. You could develop a report that simply consists of the chart you want to display. If you request this report through the web service, the data for your report will be returned as a byte array. You can create an image from this data and then use the graphics capabilities in the .NET Framework to alter the image to your requirements. You could create a custom component to do all this by following the Microsoft article.

Saving Bitmap File To MS Access 2003 Problem

Hi,

Problem:
I'm using C# 2005. The data type of the bitmap file saved to database is "long binary data". It should be "OLE Object".

Source Code:

Bitmap myBitmap = new Bitmap(@"c:\Picture1.bmp");<br />
OleDbConnection conn = new OleDbConnection("<<My Connection String>>");<br />
conn.Open();<br />
string sql = "UPDATE Table1 SET fldOLE = @fldOLE WHERE fldID = 5";<br />
OleDbCommand command = new OleDbCommand(sql, conn);<br />
command.Parameters.Add(new OleDbParameter("@fldOLE", myBitmap));<br />
int rowsAffected = command.ExecuteNonQuery();

Question:
How can I save Bitmap to database with data type "OLE Object"?

Laugh | :laugh:

Thanks in advance

Hi All,
I am trying to get a file from an Ftp and Copy data (*csv file) on to one of my tables in SQL 2005 database.
I am not sure but SQL server 2005 integration service has a way to create a package that allows me to do this task.

Can any one tell me how to go about it?

your ideas are much appreciated.

Thank you

Use the FTP task to copy the file to an accessable directory, then you can create a data flow task which uses a flat file source, processes the file and then puts the data in the appropriate data flow destination.

Your package designer should resemble this:

<br />
FTP Task --> Data Flow Task<br />

Open the Data flow task (double-click) and it should resemble this:

<br />
Flat File Source --> [intermediate transformations you may need (if any)] --> Sql Server Destination<br />

Just drag the items mentioned to the designer surface, open each item and set the properties needed.

Create a Command object which defines the INSERT command then create a DataAdapter object and assign your Command object to the adapter's Insert command. Make sure when you define the data table object to map the datatable's column names to the parameter objects in the insert command you created.

Why not you try this:

com.CommandText = "UPDATE tblUsers SET Password='" + this.UserName.Text + "' WHERE UserName='" + this.txtPassword1.Text + "'"

There are two major flaws in your code:

1. Generating SQL statements on the fly is generally considered bad practice. It leaves you exposed to SQL injection attacks. Instead, consider writing a stored procedure to perform your update and call it from your .NET code.

2. You appear to be storing your user's passwords in clear text. This is very insecure. You should consider encrypting your password using a 1-way salted hash algorithm.
