Databases :: Unable To Initialize Provider. Missing Or Incorrect Schema?
Jan 25, 2011
I have been trying to get a mysql database to connect to visual studio 2008 so I can use the ASP.net administration tools. I have researched this error for two days now and have tried every suggestion I could find. I am not 100% sure where the .dll's belong but I am pretty sure they are in the correct place and incase not I have added them into a bin folder inside my web application. the only other thing I can think is that maybe my mysql and mysql connector versions dont match. I am currently using mysql version 5.1.54 and my connector version is 6.3.6.0. Also I have successfully conencted to my database in the server explorer and it has already autogenerated the necassary tables into my database. It says my error is on line 59 so here is the code associated with my line 59.
I am trying to implement a super simple MySQL membership. All I want my Membership class to do is ValidateUser. Here is my method:
[Code]....
When I try loggin in, I get the following error: I have added the MySQL.Web and MySQL.Data references. I also have auto generate schema set true. What am I doing wrong ? Here is my Users table (created by myself), where the user login details are saved:
We have a site that is runnig II7 64 bit with the oracle .net 64 bit provider, when I try and open this in web developer 2010 express (I'm running windows 7 pro 64bit) it says it can't load the oracle dll as its an incorrect format. I got the impress that web developer 2010 was 64bit capable.
Ofcourse this is extremly annoying as I don't get any syntax formatting for the project or intellisense.
I have myConnectionString and it's working fine. In the Server Explorer, the Data Connection is even using myConnectionString to connect to the database. When I created my .dbml, it uses that same yConnectionString. However, now whenever I opened the .dbml file, pops up with the following message:The connection property in the web.config file is missing or incorrect.The connection string from the .dbml file has been used in its place.After this message is display and I clicked okay (because that's the only option), it creates myConnectionString2 in the web.config file with a different ID but no password provided. What is this all about? Why is it creating a second connection string with a different ID?
I am writing an iPhone web app for tracking business mileage. The app uses AJAX and HTML 5 manifest caching to enable offline use. The data is stored on the server in a SQL Server database with the following schema:
When there is no network available, the app stores new data in a local database with the same schema using SQLite on the iPhone. Once a connection is aquired, the app automatically uploads the new data to the main database for permanent storage.
Now, here's the question: I have data from two databases with the same schema. How do I merge the new data into the main database using LINQ? The primary key IDs in the new data must be discarded and regenerated by the main database so that there are no ID conflicts, but the two relationships must be maintained properly.
I am trying to create a Forms Authenticated site and have already used the aspnet_regsql tool to create the necessary logic in my SQL Server DB to hold my data. Now, I am looking to create a custom Membership, User and Role provider for my DB model. I was looking at the following video: [URL]
Now, I get the concept on how to go about it but I notice that this guy uses custom DB Procedures as to the ones that are generated by the aspnet_regsql tool. Can anyone direct me on where I can find info on how to go about building the Membership, User and Role provider class using the DB structure that aspnet_regsql generates? So much junk on google that I am having a hard time finding good guidance.
I just recently uploaded my site in web hosting, soon as it was live, I found out that the Ajax was not initializing or not working.
I look into javascript error log, and its pointing at
Sys.WebForms.PageRequestManager._initialize('ctl00$ToolkitScriptManager1', document.getElementById('aspnetForm'));Am I missing something, or is this issue can only be resolved by my hosting? My concern is since AjaxControlToolkit is a class DLL, it should not be a problem right?

I have one Main crystal Report where I am importing two sub reports.
Single report is working fine but after adding sub report it is throwing the Error.
(I am not showing report. report is downloaded as PDF)
Logon failed. Details: crdb_adoplus : Object reference not set to an instance of an object.Error in File C:DOCUME~1a422846LOCALS~1Temp ptMain {60D10EF9-D186-4074-90E3-64D6F0D17B02}.rpt: Unable to connect: incorrect log on parameters
rptMain has two sub reports.
Code: DataTable dt =(DataTable)Session["Details"] ; ReportDocument rptDocument = new ReportDocument(); ExportOptions exportOptions; CrystalDecisions.Shared.TableLogOnInfo myLogin; myLogin = new CrystalDecisions.Shared.TableLogOnInfo();
I have a Excel user application which has a user form (named 'Registo') that displays criteria and an image that has been entered in it's corresponding spreadsheet. This works the way it should. There's also the ability to search the spreadsheet via a form (by clicking 'Pesquisar' button) this opens a search form. However, I having a bit of a problem with it. When I try to search for something it basically doesn't do anything at all. It just sits there. So I tried to debug it and I think I'm having a problem with either the JET db engine or somethign with teh query or maybe I don't have the correct reference.
am using VS 2010 with Oracle database 10g. I get the following error only when i deploy my application to the server:Unable to find the requested .Net Framework Data Provider. It may not be installed.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
I have Asp.net application which I have created on the vista 32 using vs 2005.Which uses MSDAORA provider to connect to oracle,which works fine.ut when we are deploying on windows 2003 server 64bit it is giving the below error:Excetion: System.InvalidOperationException: The 'MSDAORA.1' provider is not registered on the local machine.I have search on the google for the solution and found that:switch the appication to 32 bit and use a 32 bit Oracle client'vider instead (Ie, Oracle's provider - ORAOLEDB.ORACLE)ORAOLEDB.ORACLE and it will work.
I have MySQL database, and I just installed the MySql-Connector-Net. But MySQL Provider doesn't appear in the list of providers e.g. in the Server Explorer.
I have a crystal report using store procedure with DSN Name: 192.168.0.3. when I keep the connection to this server it's OK
But when i change the logon info and disconnect to the server to connect to My PC it appear the error : "Unable to connect: Incorrect log on parameter"
I am having the error stated above. The stack trace is as follows:
[Code]....
Some info's:Server: Windows Server 2008 R2
.NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.1
Oracle.DataAccess, Version=1.102.3.0bit
.NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.1
Oracle.DataAccess, Version=1.102.3.0
My Code: OracleConnection cn; String con1 = ConfigurationManager.ConnectionStrings["myConnectionString"].ToString(); cn = new OracleConnection(); [code]....
I have checked all forums and posts regarding this error. They mention that there are 2 versions of Oracle.DataAccess.Client on the server, I only have 1 version. This runs on VS2010, but when I publish the website the error above shows up. I checked my Oracle connection from the installer and connection test passed. I tried uninstalling Oracle and reinstall, but still the same. The query above I tried changing to 'select region_code, reg_rom, ...', still the same error..
I just downloaded and installed the most recent MySQL .net connector, 6.3.6 and it connects to the DB just fine. My problem is with the web.config settings I have set for it. It seems that theMinRequiredNonAlphanumericCharacters property is hard coded to '1'.I've changed this to 0, 5, or any other number. I even setup a web page to just display the properties of the provider. If I change the values in the web.config, the values update. It seems that MinRequiredNonAlphanumericCharacters won't change.
[Code]....
Again, the DB connection works just fine, reason I did not post the connection string. The min password length at 44 was just for testing.
[Code]....
Of the three I only tested, only MinRequiredNonAlphanumericCharacters stays at '1' no matter what I change it to in the web.config. I even changed it to 'abcd' and received no .NET runtime errors. Me thinks it is hard coded some where or I'm not using the right property name in the web.config. I copied the web.config value straight from the example in the documentation that came with the MySQL .net connector.
When I open an ASP.NET 3.5 project using VWD2010, I get a prompt error message,"The connection property in the web.config file is missing or incorrect.The connection string from the .dbml file has been used in its place."however, my project works successfully.
I was working away on my project in vs2010 and did a build and received aCould not load type 'TestProject.MvcApplication'. I then had a look in my bin directory and the TestProject.dll is missing and I cant get it back even if I rebuild.
How can i call db2 store procedure with parameters from asp.net ( C# ) using Microsoft OLE DB Provider for DB2. I am able to connect to database. What is the syntax to call a store procedure?
