How To Use For CMS Project - SQLite Or SQL Server Compact
Apr 18, 2010
I am working on a CMS project using ASP.Net 3.5/Visual studio 2008.This is the first week of the project and I am working on the design of the system right now. Needless to say that this is my first project of this scale and I have no idea of what I am doing.
The requirements of the project ask for a light but functional CMS, one which is easy to deploy.So the question is which database to use in this scenario SQLCE or SQLite?
I am trying to open this file which exists and runs fine on my development machine. But when I deploy to my VPS with IIS8 I get this error:
An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.BadImageFormatException: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)
I copied the same data.db file from my machine to the server which worked for me. Do I need to do anything in IIS8 to recognize this file and let me use it?
Code:
Using conn = New SQLiteConnection("Data Source=" & Server.MapPath("data.db"))
I want connect to SQL Server Compact 4.0 in my ASP.NET application..
Here is example of code:
protected void Page_Load(object sendhttp://stackoverflow.com/questions/asker, EventArgs e) { string connStr = "Data Source=D:\MyDB.sdf;"; string sqlStr = "select * from tblMyTable"; var sqlDataSrc = new SqlDataSource(connStr, sqlStr); GridWithUrls.DataSource = sqlDataSrc; GridWithUrls.DataBind(); }
But I have the next error: "A network-related or instance-specific error occurred while establishing a connection to SQL Server.The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)"
The SqlDataSource has constructor with three parameters, one of them is 'providerName' so, how to specify that I want definitely use Sql Server Compact provider ? Also I have added System.Data.SqlServerCe reference..
I'm currently trying to install the "new" Microsoft WebMatrix Beta 2 (a web programming IDE). I was trying to use Web Platform Installer for this. But it 404's on the SQL Compact 4.0 CPT2 and it's tools. I was able to get the runtime from the Microsoft downloads page but the tools I am not able to find. I can not install WebMatrix because the tools are a prerequisite.
I just downloaded the above but when I look in visual web developer 2010 express I see no data provider reference .
I was wondering how to attach/create db? in the above, is it a clickable option in tools .net framework options or is VS 2010 not ready to use SQL CE 4 yet,
i have installed visual studio 2010 sp1, i have installed everything to do with compact 4 from web platform installer. yet when i try to connect to a compact 4 database, their is no choice for compact 4, there is a choice for compact 3.5 but no 4. If i try to connect using tthe 3.5 choice i get an error. i can add a compact 4 database from the new items menu. but i can not make a connection to it.you can see in this tutorial compact 4 listed in the add connectiojn box, but it is not listed in mine[URL]
what is exactly Sql server compact edition? it says that I do not need a sql server to store my databases if I use that in my bin folder? so I can use my mdf databases in app_data folder. is that true?
How can I handle more than 4k of text on the new SQL Compact Edition 4? nvarchar only supports 4k and when I change to ntext, I get the same exception as I get using nvarchar(4k), when using the Microsoft.Data wrapper included with Microsoft WebMatrix. Should it normally work using ntext?
I have ported an asp.net application form SQL Server Express to SQLCE 3.5 in Visual Studio 008. Although not recommended, everything works like a charm, except for creating datasets for use in SRSS reports.
The Dataset Designer lets me design and test the Tableadapter perfectly, but the XSD fails to compile, and returns error message :
Failed to generate code. Exception of type 'System.Data.Design.InternalException' was thrown.
I started the Bakery site demo...everything runs fine on my local machine.When I publish the site to production server in w2k8r2+iis7.5 and with .net 4.0 (integrate) pool, my bakery apps not able to connect to the .sdf file.
Error I got is :
Connection string "bakery" was not found. Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code. Exception Details: System.InvalidOperationException: Connection string "bakery" was not found.
Source Error:
Line 2: Layout = "_SiteLayout.cshtml";
Line 3:
Line 4: FacebookSocialPlugins.Initialize("[xxx]", "[xxx]","bakery");
Note the "this.Date" part of the command. Now Date is an abject of type DateTime of C# environment, the DB doesnt store it(somewhere in SQLite forum, it was written that ADO.NET wrapper automatically converts DateTime type to ISO1806 format)
But instead of this.Date when I use sDate (shown in the first line) then it stores properly.
My probem actually doesnt end here. Even if I use "sDate", I have to retrieve it through a query. And that is creating the problem
Any query of this format
SELECT * FROM <Table_Name> WHERE DATES = "YYYY-MM-DD"
returns nothing, whereas replacing '=' with '>' or '<' returns right results.
So my point is:
How do I query for Date variables from SQLite Database.
And if there is a problem with the way I stored it (i.e non 1806 compliant), then how do I make it compliant
I currently store ASP.net application data in XML files. Now the problem is I have asynchronous operations, which means I ran into the problem of simultanous write access on a XML file... Now, I'm considering moving to an embedded database to solve the issue. I'm currently considering SQlite and embeddable Firebird. I'm not sure however if SQlite or Firebird can handle multiple concurrent write access. And I certainly don't want the same problem again. Anybody knows? SQlite certainly is better known, but which one is better - SQlite or Firebird ? I tend to say Firebird, but I don't really know. No MS-Access or MS-SQL-express recommodations please, I'm a sane person.
i am trying to use a compact db in my web site, all works well with a absolute address to the file "c:mydirmydb.sdf"
but i dont want to use a absolute address for deployment reasons. i want to use somthing like |datadirectory to find the file.
This is a connection string for a entity model. somthing like < add name="MyEntities" connectionString="metadata=res://*/Entity.csdl|res://*/Entity.ssdl|res://*/Entity.msl;provider=System.Data.SqlServerCe.3.5;provider connection string="Data Source=|DataDirectory|mydb.sdf;Password=xxxxxxxx;Persist Security Info=True"" providerName="System.Data.EntityClient" />
have been trying to implement in a different scenario the example at the following URL: http://blogs.msdn.com/b/markprenticems/archive/2007/03/27/introduction-to-windows-communication-foundation-for-the-net-compact-framework-messaging-stack.aspxHave tried few things, but I cannot find a way to modify the following snippet (included in the above link) to send requests to methods with different parameters/signatures
When I turn on Code Coverage in my test settings, on a project that references the Unity DI container I get the following error:
Cannot initialize the ASP.NET project'{Project Name}'.
The event log specifies the following reason:
Could not load file or assembly 'Microsoft.Practices.Unity, Version=2.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. Strong name signature could not be verified.
I'm getting "Cannot connect to ASP.NET development server" almost every time I stop the ASP.NET server before restarting the project in debug mode. It can take between 15 seconds and 2 minutes to get the error message, and Visual Studio is frozen.
Sometimes I get three in a row, and I have to wait 2 minutes each time, or go into Task Manager and kill to process. Then I have to start Visual Studio 2010 again, which is at least three times slower than Visual Studio 2008 to open.
It's *extremely* annoying. I know I don't have to close the server if the code has changed, but sometimes I simply want to restart my website in debug mode (there is a cache on most web service calls, so this clears the cache). A workaround is to add "foo" code to a class and restart the project.
I'm running Visual Studio 2010 Professional on Windows Server 2008. I'm running the Visual Studio Power Tools too, with the latest update.
I am developing and app to find automatically characters stats with the 2nd edition dnd rules to be easy for my party to create characters when we play.
I am using Visual studio 2010 c sharp express and Sql 2008 express R2.I have added a database in the project to have all the data needed. When I use the release folder or the debug folder on other pcs the app doesn't run. Wherever I install SQL server (database and management) things are fine. I googled but I am not sure what to look exactly for and made a brief search here but with no results. I am trying to make sth that has almost no dependencies but well I can't avoid installing .net framework 4 everywhere...
Is there anyway to make database work without installing SQL? Is there any workaround like a dll or sth?
this is my 1st time uploading any database to Host Server. I have purchase DiscountASP's domain and MS SQL 2005 database addon. I can make my website to copy to DiscountASP's domain using the Visual Web Developers copy website wizard and it works great.
Now i have a database in my website which i wanna upload to DiscountASP's MS SQL 2005 database that i have bought, but i dont know how to upload it and then how to make the connection between my Website and the uploaded database. Is it that i have to copy the website(containing app_data folder containing database) to the host and it will work, or i need to copy the database separately and then make a connection in my website and then copy the website?
