Modifying An Existing Image Using Values From Database?
Aug 3, 2010
I have an image (consider the image of a clock). I would like to change the position of the dials depending on values retrieved from database. (This will probably be done using a service which will run every minute or so.) I just want to know how I can change the image (i.e modify the existing image).This is for a dashboard screen. The images would be refreshed every minute to get the latest data.
i m using a regex to not allow certain characters, the below code works fine for certain html tags but not for all for i dont want the user to enter html tags for eg if i enter <nitin/> it allows but i dont want this to happen for other html tags it does not allow
!@#$%^&*()+=[]\';,/{}|":<>? or !@#$%^&*()+=[]\';,/{}|":<>/>?
I have data entry form like...There are some empty rows and some of them have values. User can Update existing values and can also fill value in empty rows.I need to map these values in my DB table and some of them will be inserted as new rows into the database and existing record will be updated.I need your suggestions, How can I accomplish this scenario with best approach.
I want to compare a user-entered value on a Web form against an array of existing values from the database, and do so on blur. If match, then show error. Scenario is to stop user from needlessly filling out other fields if this record has already been entered.
how to trigger this? What parts are client-side, what parts are server-side? Can I do it without Javascript?
I am having one column in each row of my radgrid in which i want to show an image. I am getting values from database saying 1,2 for that particular column and for each of these values i want to show different images for different values. For Example if i am getting 1 from database i want to show "roseImage" and for 2 i want to show "lotusimage",
you could create your own custom Profile provider that operates against existing database tables .i want u to help me out if u have an idea where i can get steps by steps to carry out the above operation.i know there are various options in creating profile , particularlly the use of web. configuration, the default ASPNETDB, and XML files, BUT i wish to use an existing database which i prefer.
Creating a system with web front end and SQL backend (microsoft obviously). I have tried using the asp.netsqlprovider but i can;t as i am only allowed one database on the server, so i then tried to update my current database with the triggers to input the schema into the already existing database.Next step i create my own table with two simple fields of username and password and try and authenticate that way, i can't get that to work either.
I ahve limited permissions on the network as i am a University Student. I really don't know what to do. Never had to create a log on system before and i thought it would be far simpler than this. I ahve used Microsoft's sqlprovider schema before and it worked fine. I have also authenticated via IIS and AD too before. I can't do any of those two in this instance it seems.I need an alternative for logging in users, if needs be in can be crude. I also still need to have some kind of two different views too for logged in users and not logged in users, but that can change if needs must.Don't let me down people, haha. Think this posts in the correct place, i could not find another one i thought could be more relevant.
I have an existing SQL database containing student:class enrollments and would like to add a login feature using asp.net's built in Membership and Roles management tools. to how to integrate the Application Services Database with an existing SQL database? Once I have created the Application Services tables using aspnet_regsql tool how and where do I create a link between my tables and the .Net Membership tables?
I have a development database and one in production. There are two different sets of data in each database. On my dev system, I have mostly dummy data that I test with and in production is the real data for my web application. I recently added a new feature to the app that required a new table, and a new field for a foreign key in an existing table. I now need to upload that new structure to the production database without overwriting the live data with my test data.
If I run the Database Publishing Wizard, and choose "Schema Only" will it import the new structure and leave the existing data alone, or will it drop the records in my production database tables?
if (dt.Rows[i]["Code"] == code) { Label lblLang = (Label)(((e.Item as GridItem).FindControl("lblLang") as Label)); lblLang.Visible = true; } else { } }
I am adding a new language Fr-FR in the code above. fr-FR already exists in my DB's Language Table. I do not want to add duplicate values in my table. There should be only one fr-FR.
In my asp.net project currently i have business logic and and data access code in two sub folders(BLL,DAL) which are itself located web site project's app_code folder. I need to segregate them to two separate projects(one project for business layer and one project for Data access code).
How can I maintain connection strings necessary to Data access project which are currently in web.config file?(i.e if I choose Class library template for creating DAL and BLL projects) How can I maintain various other web.config key values that are currently used in BLL, DAL code files?How can I deploy compiled project? (ie Web site project I am currently deploying bin folder to Staging> production but this way where should i put DAL.dll and BLL.dll and relevant config files)
I have a post-only action that has a different route. In my form, I need to post to it, but also keep the querystring values I currently have.
Initial response: /my/first/path/?val1=hello Needs to post to: /my/other/path/?val1=hello
It seems when I specify a route, it of course only returns the route and doesn't append the querystring values of my original page (for obvious reasons).Is it possible to cleanly append querystring values to my the action attribute of the form tag?
i red some stuff, and what i got is that mvs normally works not directly with MSSQL on pc but witht he one it creates within project.. hm.. like that, and you can not see the database created from the project in normal SQL server databases.

Pardon if this is a very dumb question, but I was trying to migrate an existing ASP application to asp.net MVC, and followed the procedure from the music store tutorial (http://www.asp.net/mvc/tutorials/mvc-music-store-part-4), which involves adding the database to the App_Data folder. (I had to restart my machine before it would work, since otherwise, Visual Studio thought the database was being used by another application.)
Now when I check in Windows Explorer, it looks like the database file was literally copied into the App_Data folder, and now I have two mdf files on my hard drive with the same name. What is going on there?
Will my MVC app ignore the original (real) database and use it's own private copy instead? (That would be bad.) Or is the new copy just for reference when using wizards that generate entity classes etc.? If the latter, what is the procedure when the real database is modified, to update the application code?
I was reading through this post here http://www.misfitgeek.com/op-ed/adding-asp-net-membership-to-your-own-database and thought to my self what the common practice is. What do developers using ASP.NET membership and authorization in their applications recommend as a best practice? creating the membership tables in the same database that stores their applications data or configuring a second database to store ONLY the membership information?.
My current setup is a different database for membership information ONLY but am thinking that increases the number of databases i have to maintain. If I have 5 applications using asp.net membership, then that means 5 more asp.net membership databases. So do you normally create the asp.net membership tables in your main database or you configure a separate membership table? what do you recommend.
This is something I asked about a long time ago but there wasn't really a solution available at the time. There was talk of there being changes in a new roll out of EF where existing databases based on a model were simply ammended instead of being dropped and recreated every time.I was wondering if anyone knows whether or not there is something out there now that will let me retain the existing data when making changes to a model? If not, what is the best way for me to back up the data prior to a change and restore it post-change?
I am newbie to asp.net.I want to create roles for the existing users in my database. I dont want to use the membership provider database n roles provided with it.(i don't want to use aspnet.mdf at all)
I am create roles for my existing users n assign i wanted to assign the particular roles to a particular assign.
I was trying to upload the database of my ASP.NET website. On the local machine, if I copy the database from another machine, I have to attach it through SQL Server Management Studio and then use it in the connection string like
[Code]....
My database is approx. 10 MB in size for now. If I upload it via ftp to App_Data folder, how would I have to attach this database?In Plesk, I have the option to create the database and its user (as shown in the screenshots):1) Web Applications and services-Plesk2) Add New Databaseand add new database user3) Webadmin>ASP.ET Enterprise ManagerBut this is for the new database I created. My problem is to upload an existing one.There's also a section in Plesk for ASP.NET settings (as shown below)
This has the option to change the connection string etc.I also asked my hosting provider about the method to be followed for attaching the database that I would upload. This was the reply in quote." mdf ldf files perhaps will be working at your local computer but this way database of mssql will not work on web server as on web server you will be required to create and restore your database backup file using plesk control panel.
Sample connection string for asp.net mssql `Standard Security`: "Provider=SQLOLEDB;Data Source=Your_Server_Name;Initial Catalog=Your_Database_Name;UserId=Your_Username;Password=Your_Password;"
Server name to be used in coding: localhost Catalog/ database name , database user and database password you will be required to create your own using plesk control panelI would be really be appreciative for the steps I have to take to upload my existing database. How do I have attach it? What connection string I have to use?
