I'm trying to understand what exactly the .. notation does. I thought it was a range, but in this case it does something different. 回答1: With git log (and all the other Git commands that take a similar argument set), it's a specification of how to find a range of revisions, yes. Remember that in Git's general world, that means some subgraph of the revision graph--- to most people, it generally means just a range of revisions in a list. (And if you don

The problem I'm having is that this really confuses the source view of my aspx pages. Here is the code inside each of my aspx.cs pages which actually attatches the MasterPage to each content page, but as I said, now, my <asp:Content> tags get really confused and I cant CTRL K + CTRL + D my content pages anymore, it throws validation errors on EVERYTHING. HELP! protected override void OnPreInit(EventArgs e) {

The data displayed is in a master/detail format, whereby clicking the '+' at the start of the row expands the detail for that master row. I have implemented this by binding the grids datasource to a dictionary of objects that contain their own Dictionary property (to hold the detail). Problem What I want to do is format the data in specific columns of the detail. However, I cannot get hold of the column, presumably because it is a sub-element of the master row (and therefore does not get checked?) Below

The master machine replicates data to the slave. When the master replicates data to the slave, the slave machine has to do a write which would lock up the row. Reading from the slave machine is faster but why? 回答1: The Master is very busy It writes data in parallel (that's obvious) It incurs disk I/O writing to binary logs, serializing the collection of completed SQL into its binary logs It manages replication in terms of passing

Basically, my file uploads fail due to post_max_size limits being reached, even though the local directive is set to 96M, and the file is 25M. I've ensured everything else is correct, including max_input_time , max_upload_filesize , and the IIS FastCGI idle time. All these are plenty large and not the issue. I am overriding the post_max_size directive through Plesk, which (I believe) stores the change in a registry
