c# - Upgrade an existing application to include ClickOnce -

-

Is it possible to apply clickon functionality to an existing application?

The scenario is: Version 1.0 is already installed in the client premises, I would like to send them a new setup package which will be upgraded to 1.1 which has the functionality of clickon, making future upgrades "easy" can go.

Except it, is there any other solution to such a problem?

PS: Was developed with the original application (i.e., .NET 2.0). I'm using now.

No, this is not possible with the standard click-on deployment scenario.

Once clicked on the client side there is a sandboxed installation it will not know about version 1.0 already installed. It's just going to see if its click-through has already been installed, and if it has been updated, but only if the previous version has been deployed through click-on.

In your case, if the user installed version 1.1, both versions will be installed on one side, Version 1.0 will not be updated, since ClickOnce does not know that there is an association because it is a different method Was deployed through the medium. If they do not want version 1.0, they have to manually remove it. After deploying version 1.1 through ClickOn, later updates will work correctly.

Think about the click-on why you are not "involved", think of it as a method of deployment.

Alternatively:

I should make it clear that whatever you are looking for with the addition of standard click-ON is not possible, however, Mentioned that you want to send them the initial setup file. In that case, you might have a workaround:

  1. Automatically script the setup file to remove version 1.0 installation
  2. Launch the ClickOn installation Scrip the setup file for.

For subsequent updates, simply tell the user in the "Pure" click-over setup package, and your updates should work fine.

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
