c# - Create a document library with external persistence -

-

I would like to create a custom document library, where I use the standard UI but implements a different persistence layer. Basically getting and displaying documents from a different source system. In this way I can use my existing object model, but I can take advantage of great office integration in SharePoint.

I found a good article but they are cheating, they have coded an entirely new UI for external solidarity.

I have seen the SPList and SPDocumentLibrary objects but I can not override the necessary methods.

I have seen the structure of the incident and it is close but important events like 'GetFile

It's not the one that you are trying to do right (or perhaps a "good") fit, but I mainly mention it for awareness and possibly giving you some additional thoughts (and warnings).

The SharePoint's storage infrastructure takes advantage of two different back-end stores: one for metadata (always the SharePoint SQL Database), and one for blob storage (also by default SQL). In its current form, however, SharePoint allows your own Bluetooth storage provider "Wire-In" via some kind of implementing the ISPExternalBinaryProvider interface. Wiring enforcing this kind of interface allows you to continue to store metadata in SQL, while stores documents and other blob item types in a different store of your choice.

It may seem somewhat promising, but a couple of serious thoughts:

  1. There is a field-wide effect of stars in their own ISPExternalBinaryProvider Nothing, so when the provider gets wired, all sites and libraries will be able to use the new provider.

  2. You will need to dive into unmanaged code, just like ISPExternalBinaryProvider you are required to work with some IDLs.

You can read more here:

It is my taking that external blob storage (EBS) systems at some point of "prototype" Is not ready for prime-time if nothing else, however, it gives you something to think, SharePoint Server 2010 hopes to do more with it and make it more attractive and easy to implement.

What is the value for it!

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

Visual Studio 2005: How to speed up builds when a VSMDI is open? -

-
Using Visual Studio 2005, if I open the test in VSMFI and try to run the tests, then sometimes the projects are ready. However, they run very slow. CPU 99% waste and output window VS Shows things associated with compiling it. Is there any way to fix this? It does not make any sense. It is not necessary to upgrade that we are a viable alternative to those people who have to deal with the legacy code. Did you try to upgrade SP1? I do not know of any specific problem in this area, but this will be the first change I tried to do.

booting ubuntu from usb using virtualbox -

I am trying to install Ubuntu on a USB, the problem is that I do not want to repeat the boot once, I want to keep my windows, but I want to boot Ubuntu using the virtualbox and USB to the Ubuntu Want to use my hard drive, but how? The virtualbox will not recognize USB as a hard drive when installing an ISO In virtualbox, you have to create a virtual hard disk. Make a USB drive and tell the virtual box to install a virtual hard drive that you just created. EDIT: To answer some more questions: In the new Virtual Disk dialog, click the button next to the location field, click on the button Virtual Disk on Flash Drive To access, click the arrow next to Save in the Select File in the window next to Save In, and you can access your flash drive from there. I recommend setting the image to be allocated dynamically, because the size of your flash drive is not available disk space. I name the image, then select that image to install Ubuntu in the Verbill box. The virtualbox will never
