835813Feb 1 2011 — edited Feb 1 2011
Hi , I am using JCChart in my project and using applet to display the chart. The chart is created at the client machine by the applet. now there is an option to export the image as a gif file of the chart to user, so when user click on export button then the image should be save in gif formate on the server. at server side as a scripting language I am using asp. Please tell me How can I save this image On the server directory by applet

and I have to follow the http protocole thats why I try it with HttpURLConnection but I become unable to directly save the image on the server directory please tell me the exact way so that I can save the image.

if there is any other better way to do this please tell me

Thanks and Regards

I tried your C# app with a table using a DATE column and TIMESTAMP column. In both cases with either ODP.NET Core 2.19.80 or 2.19.70, I didn't hit an error. I used DB 19c. Which DB version did you use?

I found out that there must be at least one record in the table. For example:

Table Design:

Name
Type
Size
IDNumber0
DateDATE7
TimeTIMESTAMP0
Time2INTERVAL DAY TO SECOND0

Table Data:

ID
DateTimeTime2
1(Null)(Null)(Null)

Then replace the [column] in the sql below:

var sql = $"select(CASE WHEN 1 = 0 THEN a.\"[column]\" ELSE NULL END) as C0 from \"YOUR TABLE NAME\" a ";

 

[Date]: reproduced

[Time]: can't reproduce

[Time2]: reproduced

DB version: 11/12/18/19c

I added the interval column and added one row of data, but still can't reproduce the problem with the 2.19.80 version against the data or interval column. Do you want to send us your trace? Just add these two lines and run your app.

OracleConfiguration.TraceFileLocation = @"D:\traces";

OracleConfiguration.TraceLevel = 7;

You can send the trace file to dotnet_us (at) oracle.com.

Thank you. The email has been sent. I hope it's useful to you.

This bug appears to be the same as Bug 26123054.

Will this problem be fixed recently?

The bug hasn't been fixed yet. We're still evaluating the root cause.

Answer

The bug has been fixed in our main code line. My expectation is that the fix will be in the ODP.NET Core 19.10 release.
