currently investigating SharePoint for our company as a means to make Excel processing accessible through our web application without relying on the Office Interop DLL files. (our sysadmin doesnt want to install Office on the production server, for good reason)I'm aware that Sharepoint has an Excel Webservice that can be enabled and used by the application. The problem, if it is a problem, is that I need to make a class that wraps all the logic for transforming an Excel into HTML.So I need to add the references to this webservice to the application.
But what if we need to deploy the application with a customer that has no SharePoint server available, will this cause a problem in the application? We will use checks to make stuff visible and invisible depending on whether a parameter is set, but I'm looking for a means to ensure that I can for example add the required references at runtime when I need them for Sharepoint.
I try to read a file from SharePoint document library through httpwebrequest.For that I have to pass the credentials.So How should I pass the creadentials.
I have an asp.net 2.0 web application that will run on the same web servers as SharePoint Server 2007. The application should run in its own App Pool (IIS 6.0). The Web Application needs to call the SharePoint Object model API.
Is there a resource that explains the required configuration / security settings and other considerations? It is possible that I need to make some settings in SharePoint Admin Console itself; aswell as config files. Script files might need to be located in a specific location in order to be accessible. Assemblies may need to be signed.
I can only get partial success running my Web application. But only if it is deployed to a Virtual Directory that resides under the SharePoint Website (in IIS & File system). Even with this setup, I JQuery / Javascript throw errors when accessed (object null); and also images not loading.
I have made some changes to the Web applicaton web.config file which have allowed me to run the application albeit the above mentioned issues with scripts and images (Virtual directory properties also set to allow scripts and executables to run). Ajax functionality appears to work OK.
I'm developing an ASP.NET user control in VS2008 that writes to a SQL Server 2005 database. I've published the control to a SharePoint 2007 MOSS page using the SmartPart addon. The control consists of a few text fields and a submit button that writes the contents of the text fields to the database. When I test the control in the Visual Studio debugger, it works fine. When I try to submit data from the SharePoint page, I get the error shown at the end of this post. Last time I saw this, it was a database permissions error, but I've granted my site's default application pool read/write access to my database. Does anyone have any idea what else the problem might be? Also, how can I double-check the credentials that the SharePoint page is using to access the database, since I still suspect that this is a permissions issue?

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
//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]...

It installs the webapp and puts it into the appropriate virtual directory.
So far so good.
