Configuration :: Custom Web App Integration Into Sharepoint With MS-Access Connectivity?

Jan 10, 2011

Ive integrated a custom web application into a Sharepoint site by creating a virual directory, that contains my web app files, that points to a directory in the Sharepoint inetpub folder.

On my local dev server I can access all my web app pages just fine by typing in /virtualdirectoryname/page.aspx

My Problem is that: When I deploy to my Live Test server that is internet facing, none of the pages that make a MS-Access database call will work.

The Error I receive is '[SecurityException: Request for the permission of type 'System.Data.Odbc.OdbcPermission, System.Data, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.]'

I have researched the issue online and tried numerous solutions which include giving all the assemblies in my application a strong name, and modifying the security policy to trust this strong name.

My Custom Web App consists of 2 projects

1. A Class Library Project (Data Layer)

2. A Web Application Project (Web Layer)

My .mdb database file is stored at root level within the Virtual Directory.

I have 1 class in the Data Layer (ClassConnect.cs) that when instantiated, creates the ODBC connection for all other pages to use (OdbcConnection dbConn = new OdbcConnection();)

I have a Connection String stored in the web.config file that is as such. When I deploy to the Live Test Server I change the path in this connection string, because I haven't figured out yet how to get a relative path that works.

I also place the dll's for my 2 projects in the Sharepoint bin folder.

Could anyone suggest what might be the dfference between my Local Dev Server and the Live Test Server and why I might be getting these errors.

Unable To Call The SharePoint Custom Web Service From Another SharePoint Farm

Jan 12, 2011

I have deployed a custom SharePoint Web service on Farm A. I am trying to access this Web service from a SharePoint timer job on Farm B. On Farm B, I am creating Class Library project, packaging it (wsp) and then deploying to GAC. The problem is I'm unable to access the Web Service using the following code. TodaysNewSVC is a service reference

TodaysNewSVC.GetTodaysnewsfromInsite objGetNews = new TodaysNewSVC.GetTodaysnewsfromInsite();
objGetNews.PreAuthenticate = true;
objGetNews.Credentials = CredentialCache.DefaultCredentials;
objGetNews.Url = "http://insite-dev.portal/_vti_bin/todaysnews.asmx";
DataTable dt2 = objGetNews.getNewsFromInsite(true, true);

//getNewsFromInsite is a WebMethod which returns the DataTable.

Note: Both farms use the same active directory authentication. I have also done the debugging for Timer Job and feature activation and they are working fine. The problem occurs during the call i.e. getNewsFromInsite
The asmx and wsdl files are accessible from Internet Explorer and also from Windows Console application. Here is the code which I use from console application:

GetTodaysnewsfromInsiteSoapClient objWSClient = new GetTodaysnewsfromInsiteSoapClient();
objWSClient.ClientCredentials.Windows.ClientCredential = System.Net.CredentialCache.DefaultNetworkCredentials;[code]...

Here is the error message:The request failed with the error message:
<html><head><title>Object moved</title></head><body>
<h2>Object moved to <a href="%2fPages%2fproblem-with-page.aspx%3fc%3d500">here</a>.</h2>

Sharepoint - Simple Web Form That Writes To A Database... Access Web Form Or Custom .NET?

Feb 21, 2011

I am working in a school and we recently installed a new server running WinServer 2008R2. I want to be able to point people to a URL on our intranet and have them fill out a simple registration form and have this data written to a database. It would also be nice to have some data auto-populate (such as their name).

Is it overkill to set up a sharepoint server and try to do this with Access Webforms? Could I use something like dotnetnuke and find a module that works? Or how about options for writing custom forms?

Custom Master Pages In WSS3.0 / SharePoint 2007 DOC TYPE?

Mar 23, 2011

I have a custom master page that I use in WSS3.0 (SharePoint 2007) and I am using a HTML 'DOC TYPE' which I am declaring at the top of the master page. The site all works very well with my master page apart from some of SharePoint controls which are acting a little funny, namely the People Picker for a People and Group field.If I remove the DOC TYPE declaration then the People Picker and other controls work perfectly and behave as they should but it sends some of my customisations/layout all over.

Before I spend a lot of time reviewing fixing the issues I get to my design without having the DOC TYPE declared, does anyone know if there is a certain DOC TYPE that is compatible with WSS3.0 / SharePoint 2007 and all of its features (i.e. People Picker Fields)?

Configuration :: Web App Forms Authentication Vs Sharepoint Services

Apr 22, 2010

I am having difficulty getting an web application to run on a new server. This same app has been deployed to at least a dozen other servers without issue. The x-factor seems to be that Sharepoint Services (WSS 2.0) is present on the new machine.

The app is configured to use Forms Authentication with a redirect to a specified login page, the first symptom is that no attempt is apparently made to redirect new requests, requests proceed directly and then error out when that page attempts to look at the HttpContext.Current.User.Identity.Name.

Second, when navigating directly to the Login.aspx page, the login and authentication check appear to proceed normally, but again HttpContext.Current.User.Identity.Name is blank where is should now have the users login name, and an application error occurs. I have confirmed that the same code on other servers behaves as expected (the Name is set at this point). IIS virtual directory settings are identical as well.

It would seem that something is interfereing with the normal Forms Authentication processes and that something appears to be Sharepoint. We have already listed the web app's path as excluded in the Sharepoint Admin section. Is there something else that needs to be done?

Use Sharepoint As The Back - End Versioning And Storage For Custom Document Management Website?

Apr 16, 2010

I want to build a custom document management web application that ties in with sharepoint for the actual document versioning and storage. I'm hoping for something like a sharepoint widget that I can plug into my web application that would allow me to tie in with sharepoint and download documents, make edits to them, and upload them back to sharepoint, with sharepoint handling all of the versioning and storage. Basically I'm looking for a sharepoint API. If WSS is the answer to this, are there licensing issues that I need to consider?

C# Database Connectivity Getting Into Mess

I understand the principles of it all, but I am finding this DAL with table adapters and wizards that do too much to be really messy to work with. Does anyone have any recommendations on what I should be using instead and a link to a tutorial on how to get going quickly with it?
