I am trying to get up and running with the enterprise library 3.5. I am using Visual studio 2008 sp1 and asp,.net framework 3.5 sp1. I've followed what I believe (may be very wrong here ;) are the setup steps....1) Download / install enterprise library2) Add references to the blocks I need (common / data)3) Imports

my page is very simple, one gridviews and one ObjectDataSource.here's my code :
<%@ Page Title="" Language="C#" MasterPageFile="~/site.Master" AutoEventWireup="true"
CodeBehind="default.aspx.cs" Inherits="cHospital._default" %>

I also posted my question on another web site, one suggestion I got is move my codes to codebehind
(http://entlib.codeplex.com/Thread/View.aspx?ThreadId=245208)
But this is ObjectDataSources, my understanding is everything have to stay in Class file.
I am using daab in my web application,and 1 module requires me to insert and image and retrieve it accordingly,i would use the ID to retrieve the image,i have done this using ado.net and it works great.i am now getting used to the daab so i decided to use this.My application consists of a businesslogic layer which contains 1 class file,Images.cs.The application inserts the image and now I just want to retrieve it.I have also looked at this article

i am using,Asp.net(vb),database sql server 2005, i want to use sysdsn DSN for database connection,so please Guide me how do i use DSN using web.config and class(we have sqlhelper type our own DBclass to set connectionstring for whole applicatoin. which get connection string from web.config),
Now,how do i use/set dsn in this type of scenario.
i have set the following connection string in web.config
<connectionStrings>
<add name="Online" connectionString="Server=127.0.0.1;Database=OnlineDB;Trusted_Connection=False;uid=sa;pwd=pwd01;" providerName="System.Data.SqlClient"/>
</connectionStrings>
how do i able to get the value for the Database field
I am using CLR project in my website.I have used bulk insert in there.I am not able to use context connection in the procedure.Is there any way to get the connection string from web.configor from context connection.
View 5 RepliesI have setup and SqlCacheDependency for my site and all is working well, but there is one requirement in my task that I dont' seem to be able to find the workaround for. Currently, my code relies on the following web.config settings to allow the SqlCacheDependency to know where to connect to. it is like this:
<connectionStrings>
<add name="connstring1" connectionString="......" />
</connectionStrings>
<caching>
<sqlCacheDependency enabled="true" pollTime="500">
<databases>
<add name="db1" connectionStringName="connstring1" pollTime="500" />
</databases>
</sqlCacheDependency>
</caching>
The problem is that we can't allow in our application the connectionstring to be on the web.config. I am asked to programmatically do all of that. I don't know how and I don't know if that is even possible, is it?
I want to setup the connectionstring of the SqlDatasource of a dropdown list at runtime, eg. Page Load event. I have install MySQl ODBC driver, System DSN name as "MySQL_Employee" If I have an entry in Web.config:
<connectionStrings>
<add name="mysqlConnection" connectionString="DSN=MySQL_Employee;UID=john;description=connection to employee database;server=empServer;database=employee;port=3306;" providerName="System.Data.Odbc"/>
</connectionStrings>
Going to start this thread over so that it makes more sense.Anyways, my problem is that when trying to configure my ObjectDataSource in design mode, it only gives me 2 options and never gives me the option for the one I need. The other 2 work fine, but for some reason, this 3rd one will not show up in the list.I have a webpage with pics illustrating how I have it setup and the problem ----------> https://sites.google.com/site/configuringobjectdatasource/And I have another webpage with pics illustrating steps I have taken to fix this problem but still nothing -----> https://sites.google.com/site/configodspart2/what is going on and why it will not show up in my list when I try to configure?
View 3 RepliesI am writing an app that has a bit of process flow to it. On the save of a record, I need to check some fields to make sure they are not null. If they are not null, I will update a 'SectionComplete' field to true.
The thing is, I would like to store my fields in the web.config. So, I would like to have a string in the appsettings section that has a list of field names that are required. Then in my method, I would call these fields out and check each one for the specific record id, and then update the database.
I would like to do this in the web.config so we could add/remove columns without having to redeploy.
For example: my required fields are name, id, and phone. For section one to be labeled complete, all of these fields would need to be not null.
web.config would have this entry:
<add key="Stage1Fields" value="name, id, phone"/>
I encrypted my connectionstring and store at web.config file. Then I bind Gridview with sqldatasource control, cannot bind because of sqldatasource don't know the(encrypted) connectionstring.
View 5 RepliesStuck trying to populate a dropdownlist with an ObjectDataSource using the wizard.
using the wizard i can successfully configure the datasource, then I can choose the datasource. The next step you should be able to select your display value and the selected value. However, these boxes are not populated within the wizard. I added a gridview to test the datasource and it displays fine.

I just installed VS2010 and opened the root machine.config and web.config files for review and I found some errors. In machine.config, the following line has errors in both entries for <Microsoft.VisualStudio.Diagnostics.ServiceModelSink.Behavior>. When I hover the cursor over them I get a tooltip text which displays: "The element 'endpointBehaviors' has invalid child element 'Microsoft.VisualStudio.Diagnostics.ServiceModelSink.Behavior'. List of possible elements expected: '...(list of options here)...'. The same problem happens for the second appereance in tag <serviceBehaviors>.

Currently, I work on an ASP.NET project which is hosted under version control and is used on several developer machines, tester machine and production environment.
In three cases, configuration (Web.config) may be different. For example, developer and tester environments use testing SQL Server, whereas in production environment, another SQL Server is accessed, so the connection string is different in those cases.
We want to keep three versions of Web.config in subversion. But modifying each of three files every time we need to add, remove or change a common setting is annoying: it would be nice to have a common, master Web.config, which will be inherited by each of the three Web.config files.
How to set up an ASP.NET project which will use a master configuration file and different slave configuration files on different machines, thus sharing the same project/source code/configuration files in subversion?
When I open my ASP.NET site in IIS and try to open the .NET Trust Levels, I get an error message:
.NET Trust Levels There was an error while performing this operation.
Details:
Filename: ?C:inetpubwwwrootmyappweb.config
Line number: 445
Error: This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"),or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".
I've checked a few places, but I haven't found anything that seems like it would be locking that setting. Is there a systematic way of determining where that setting is locked?
I'm using IIS 7.5 and .NET 3.5 sp1.
We are experiencing some strange behaviour on one of our ASP.NET web servers (Windows 2003 64-bit). After some activity, two third-party controls are unable to run correctly. One is log4net (it does not write error messages out) and the other is a menu control (it displays eval message instead of picking up its license). The one common thread is that both controls pick up their config from external config files (linked to from web.config).
Just wondering if anyone has any thoughts on this or experienced this in any way. Is it related to file/folder rights? The server has been running fine for a while and just started exhibiting this behaviour. Perhaps it occurs around the time the worker processes are recycled.
I am running into a problem with a web.config in a child project that has the same connection string setting as a parent. We have this in several of our web apps but there is one case where we want a child not to use the parent web.config. Is there a setting or command in the child web.config to ignore the parent web.config?
View 4 RepliesI have deploy my web site, it contains a project!
in MyWeb there are all the aspx page and some entites datamodel, in MyApp there are the class with function like "getter data from DB" and there is a entity data model.
afeter the deploy, I have only the web.config and the connection string for the entity datamodel....itīs run ok, read/write the data on the DB.
The problem is with MyApp.....after the deploy it is a dll file and I donīt have the app.config and the entity inside it donīt run, not read/write nothing on the DB.
There arenīt error or messager but not read/write the data in the MyApp project.
all run on the iis 7
now...the question is:
I lose the connection string (in app.config) after the deploy?
Can I put a entity in the MyWeb and read it in another project (myApp)?
ps: for connect to DB I use not the c# code:
var db=from x in AccessDB.Example select x;
I made a change in my machine.config for a 1.1 application and then later I upgraded the application to .Net Framework 3.0/3.5. Will that configuration change still apply or do I have to make that change in my local web.config for the 2.0 machine.config/web.config?

How do I engineer failover logic properly if an Assembly (.dll) cannot find a web.config file?
Background: I've got our website code nicely modularized into two different .dlls. For simplicity's sake, let's call them:
website.dll
commonengine.dll
The website code and .aspx / .ascx files calls upon the commonengine library for all data layer stuff. For connection strings, the commonengine in turn looks not to the app.config but to the website's web.config file (that's my own preference -- I prefer to have our production constants all in one place). The website code occasionally (very rarely) needs to access stuff in that web.config file. All good so far (even though not entirely pure).
Here's the trouble. I've written a third module. It's a Windows Service (specifically, it's a POP3 checker/processor -- processing mailbox requests and using the commonengine.dll for some data layer stuff). The problem is the Windows Service calls upon the commonengine.dll, and the commonengine.dll cannot find web.config anywhere because, after all, it's a Windows service (.exe) and doesn't live in a website directory.
What's the proper test/logic here to use app.config when a web.config file cannot be found?
