Delphi Dynamic Dll - global variable -

-

I am busy doing a DLL coding which provides several functions in the host application. This app dynamically loads, loads and offers dll after each function call.

I have no control over the host app. I can only work within DLL. Is there any way that I can put some variables in memory so that I can reuse them within each function? Clearly a global variable gets approved, when DLL loads by the host application.

thanks

I think you have 2 main options here.

  1. Provide 2 versions of your function, now, plus one and where they pass through a buffer (records, whatever), you can read the previous state , And of course can update the state. Call the high perf version of this function. They would like to use it.

  2. Either save the file as a cookie (basically what it is).

    3. Option 1 will require modification in the host app, but will be forced to take advantage of host app developers, option 2 will not need any change in host app , But will not be in the form of performance.

    I personally would not like to start complaining about reference counting, possibly because the host app is about to be unloaded for a reason, if I had the host application god, then I would have trouble.

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);

What is expire header and how to achive them in ASP.NET and PHP? -

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
