  • Database version is zero on initial install

    - by mahesh
    I have released an app (World Time) with initial database. Now i want to update the app with a database upgrade. I have put in the upgrade code in OnUpgrade() and checking for the newVersion. But it was not being called in my local testing... So i put in the debug statement to get the database version and it is zero . Any idea why it is not being versioned ? Following is the code to copy the database from my Assets folder ... InputStream myInput = myContext.getAssets().open(DB_NAME); // Path to the just created empty db String outFileName = DB_PATH + DB_NAME; //Open the empty db as the output stream OutputStream myOutput = new FileOutputStream(outFileName); //transfer bytes from the inputfile to the outputfile byte[] buffer = new byte[1024]; int length; while ((length = myInput.read(buffer))>0){ myOutput.write(buffer, 0, length); } //Close the streams myOutput.flush(); myOutput.close(); myInput.close(); -- Mahesh http://android.maheshdixit.com

    - by Mahesh
    Hi, I am developing contactus webpage which have a input field called Email. It is validated against a required field validator and regular expression validator with appropriate messages. Required: Enter Email Regular Expression: Invalid Email I am setting these two as given below: <asp:TextBox ID="txtEmail" runat="server"></asp:TextBox> <font color="#FF0000">*</font> <asp:RequiredFieldValidator ID="rfvemail" CssClass="error_text" ControlToValidate="txtEmail" runat="server" ErrorMessage="Enter email address."></asp:RequiredFieldValidator> <asp:RegularExpressionValidator ID="revemail" runat="server" ControlToValidate="txtEmail" ErrorMessage="Invalid Email" ValidationExpression="\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"></asp:RegularExpressionValidator> My problem is both Enter Email and Invalid Email is occupying its own space. For Ex: If I leave email as empty space and press submit, Enter Email is displaying right next to it. If I enter invalid email(xxx), Enter Email is off but taking the space, Invalid Email message is displayed after these space taken by 'Enter Email' before. Is there any way to remove this space??

  • APplication performance issue : SqlServer & Oracle

    - by Mahesh
    Hi, We have a applicaiton in Silverlight,WCF, NHibernate. Currently it is supporting SQL Serve and Oracle database. As it's huge data, it is running ok on SQL Sevrer. But on Oracle it is running very slow. For one functionality it takes 5 Sec to execute on SQL Server and 30 Sec on Oracle. I am not able to figure out what will be issue. Two things that i want to share with you about our database. 1) Database: contains one base table contains column of type SQLServer: [Text] Oracle: [NCLOB] 2) Our database structure is too much normalized. May be in the oracle i have used NCLOB, that is the cause of the performance. I mean i don't know the details about it.... Can anyone please let me know what will be cause? Or Which actions do i need to follw to improve the performance as equal as SqlServer.? Thanks in advance. Mahesh.

  • When is the right time to join open source project for programmer?

    - by Mahesh
    Most of the newcomers in programming start with basic projects to start with programming. Most of the C++ progammers spend some time with puzzles and contests but this is not always helpful. Sometimes you've to spend some time on real projects. Starting your own open source project could be a problem in self-learning for newbie cause of lack of mentors and peers who can't look at your code and give suggestions. Open source projects can solve this problem, some projects could be best suited for new programmers. Besides everybody is newbie at some point. So i'll try and make this question a bit from beginners perspective. I tried few questions on stack overflow before asking this like How do i join & Bare minimum you need and how to get involved with open source and what level of programming etc. But this is not helping me when it comes to self-evaluating with skills. How to find that out ? How can i check what it takes to join open source project and am i really that comfortable with huge source code etc. My question is when to consider yourself comfortable joining open source programming ? I mean how will you test yourself that you're ready to take burden of big/small projects of open source ? how will you test yourself to see if you could work with version control/other programmers/tight schedule etc ?

Here is brief introduction about them in my own words. (Their names are in order of the agenda). 1) Jacob Sebastian (SQL Server MVP) – This person needs no introduction. Every developer and programmer in Ahmedabad and India knows him. He is the one man who is founder of various community-related ideas like SQL Challenges, SQL Quiz and BeyondRelational. He works with me on all the community-related activities; we are extremely good friends. 2) Rushabh Mehta (SQL Server MVP) – If you use SQL Server – you know this man.

This is one man Ahmedabad will never forget. 4) and Myself. I will not rate myself in the league of abovementioned experts, but I must say that I am fortunate to have friends like those above. We also have two strong .NET presenters – Mahesh and Prabhjot. During this event, there will be plenty of giveaways, lots of fun, demos and pure technical talk, specifically no marketing and promotion – just pure technical talk.

  • Unexpected behaviour when dynamically add node in HAproxy server

    - by Anand Soni
    I wanted to use HAProxy for my web app for load balancing purpose. I am trying to add a new rabbitmq node dynamically in HAProxy server using command : haproxy -p /var/run/haproxy.pid -sf $(cat /var/run/haproxy.pid). I am doing tcp connection mode with leastconn balance algorithm in load balancing. What is expected is when there is 3 connection in one rabbitmq, I add a new rabbit server in HAProxy server. so the next connection would pass to 2nd rabbitmq server which is not happening in my case. It distributes the connection in haphazardly manner. Here is my config file: defaults log global mode http option httplog option dontlognull retries 3 option redispatch maxconn 2000 contimeout 5000 clitimeout 5000 srvtimeout 5000 listen rabbitmq 0.0.0.0:5672 mode tcp stats enable balance leastconn option tcplog server rabbit01 xx.xx.xx.xx:5672 check server rabbit02 xx.xx.xx.xx:5672 check listen tomcatq 0.0.0.0:80 mode http stats enable balance roundrobin stats refresh 10s stats refresh 10s stats uri /lb?stats stats auth admin:admin option httplog What is the problem causing this behavior? Any suggestion will appreciated.

  • How to access an SD card from a virtual machine?

    - by Punit Soni
    I want to format an SD card from my Linux virtual machine. I have a built-in SD card reader in my laptop. I tried using VirtualBox and VMware Player and installed Ubuntu 10.04 guest. None of them are showing the SD card reader as a device. I can access the SD card from the Windows host. I am not interested in solutions using shared folders as I want to access the SD card as hardware (it should show up in /dev). I basically want to set up the SD card for BeagleBoard, but I don't want to install physical Ubuntu in my PC.

  • Dump output from REPL

    - by Ankit Soni
    I'm writing SML programs, and I'd like a way to quickly see the output from running a program in the REPL without actually running the REPL (to quickly see if a program has syntax errors - I plan to use this as a make program for .sml files in vim to view the output inside vim).. Currently, I have this: sml file.sml | echo -e "\004" So it runs the program, and then echoes Ctrl-D to exit the REPL. The problem is that its too quick to send the Ctrl-D key, so there is no output. I tried this too: sml file.sml | sleep 2 ; echo -e "\004" But that isn't doing it either. Any ideas on how I can get a dump of the output from the REPL?
