size

问题 When adding a .MDF ( .NDF ) or .LDF file to a SQL Server, we have the option to set its initial size, auto-growth, and incremental (percent or absolute). After the database is in operation for a while, is it possible find how much of the actual size is used by the data? For example, if the actual size of the file is 5M, but only 2M is used to store the data, the file can still take 3M of data before it needs to grow. I need a way to find out the "2M" (used size) in the total current size (5M)

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: How do I get a directory size (files in the directory) in C#? In vbscript, it's incredibly simple to get the folder size in GB or MB: Set oFSO = CreateObject("Scripting.FileSystemObject") Dim fSize = CInt((oFSO.GetFolder(path).Size / 1024) / 1024) WScript.Echo fSize In C#, with all my searches, all I can come up with are long, convoluted, recursive searches for every file size in all subfolders, then add them

问题 while my swing app is running I change the size of the screen (e.g. from 1024x768 to 800x600). Is there any event I can listen to to be notified about this? Alternatively I could check the screen size in every couple of second, but the Toolkit.getScreenSize() keeps telling me the old value. How could I get the real screen size after the change? Environment: Linux (tested on SuSE ES 11 and Ubuntu 9.04) I appreciate your help. Marton 回答1: The following worked for me, but I'm on a Mac, so I can

问题 I'm new to Qt, so I wonder whether there is a way to set the size of a QMainWindow to (for example) 70% of the user's desktop. I tried the stretch factor but it didn't work. QWidget::setFixedSize worked but only with a pixel number, I think. 回答1: Thanks to Amir eas. The problem is solved. Here's the code for it: #include <QDesktopWidget> #include <QMainWindow> ... QDesktopWidget dw; MainWindow w; ... int x=dw.width()*0.7; int y=dw.height()*0.7; w.setFixedSize(x,y); 回答2: Somewhere in your
