in the SharePoint Recycle Bin, the Recycle Bin has two layers, the first layer is the user operation, can be deleted or restored, and the PC computer, the second layer is the site collection Recycle Bin, generally need to be an administrator to operate, after this layer is deleted, The file cannot be restored through SharePoint. Garbage collection is a slow process that can be judged by the size of the folder in which files are stored at intervals. Vii. Uninstalling RMS1. Uninstall in

Recently, the customer requested to implement the forum post attachment clipping function, did not consider JS and iOS, Android container interaction solution, simply use JS to achieve it. Due to the original attachment upload with the implementation of other plug-ins, so on the basis of a lot of effort, just put jquery-photoclip cutting function barrier up, but finally successfully achieved. In the implementation process encountered a few problems, write down to study with you.For security reas

the BLOB type is Empty_blob (). The previously inserted record is then queried with the Select command and locked, and then the empty object is modified to the LOB object to be inserted. 3. Different ways of modification. When modifying other types of fields, use update ... SET ... command. While the LOB Type field, you can only use SELECT ...
