Although this method applies to almost every form, you may need to modify the above Code. In some schemes, the control to be used by developers may not use one of the above attributes as its main interface. In this case, you need to updateFormbindingTo include the property and type. Back to Top
Conclusion
These two typesFormbindingMethod (BindobjecttocontrolsAndBindcontrolstoobject) Can be used to greatly simplify the form code, and provide maximum flexibility for ASP. NET form

, you can quickly resolve the problem to a specific TCP/IP factor. On the other hand, if the same problem persists after switching to the Net Library, You can exclude the Net-Library problem. The cause may be that the server is shut down or the network infrastructure between you and the server cannot work properly. Finally, you can easily change the Net-Library used by the application without changing the application itself, which provides you with a tool to help narrow the scope of the problem.

maximum server memory. If this parameter is not set, BPool only sets about 128 MB for use by other processes and locks all the remaining physical memory on the machine. Then, BPool uses the memory above 3 GB (AWE memory) as the paging files for data and indexing. It splits these areas (above 3 GB) the physical memory page is mapped to the appropriate virtual memory address space, so that the 32-bit pointer can be referenced.
