• chris441962 How can I make update version for application which was signed with certificate now expired?

  If I change expired code signing certificate to new one and publish updated application, client will fail to launch. And code signing fails if I try to use expired certificate. How can I make update version for application signed with old certificate I can verify that this is a problem with Verisign certificates too. I just renewed mine, updated my software, and found out it will no longer work unless I uninstall the old version first and then install my new version. This is a unbelievable oversight on Microsoft's part if there is no fix for this. How can they promote the Clickonce technology, encourage people to sign their code, and tell them about all the benefits of using this technology whe ...Show All

• licheca MessageBox from worker (Non-GUI) thread

  In a C# (.Net 1.x) application, when a user clicks on the "Run Update" button, I launch a function DoRun() in a worker thread Question 1: I need to bring up a confirm dialog while the function is running based on some condition. That cannot be asynchronous. Is it generally Ok to bring up the Dialog (MesageBox.Show.....) from the worker thread If not, what is the way to do this synchronously on the GUI thread Question 2: I need the command button (btn_run) disabled at some point in the function, and then enabled again at the end of the function. While I know how to define delegates and do this with BeginInvoke, is there a simpler way, since I have a lot of buttons and do want to define a separate function to delegate e ...Show All

• Blake01 app.application Publish file

  Hi, I know this has already been posted, but I need to get it clear in a simple way. The 'app'.application file is created when you publish an application to a web/ftp server, along with other files. The publish.htm page shows a button linking to the 'app'.application file and I can correctly install it, but a friend of mine (and maybe many more people too) get the 'app'.application file contents displayed in his browser. He has the .NET Framework 2.0 installed (installed automatically with VB 2005 Express), and I would like a simple solution to resolve this issue, without reinstalling .NET 2.0 (unless you are sure it resolves it). I also heard that it has to do with MIME types , but I'm not too familiar with this term to unders ...Show All

• Beckwith Form roll over opacity

  Does anyone know how to make a form that is set to 50% opacity and when the mouse runs over the form it turns the form to 100% and when you go off the form it returns to 50%. This sould do it: private void Form1_MouseLeave( object sender, EventArgs e) { this .Opacity = .5; } private void Form1_MouseEnter( object sender, EventArgs e) { this .Opacity = 1; } Hi, To have the required result you need to catch two events : 1- MouseMove event of the form. This event already exists in System.Windows.Form object. So when the mouse moves on the form, change the opacity to 50% (if it's not alr ...Show All

• redneon Which event is fired each time a node is added in a treeview?

  I have a treeview with nodes loaded dynamically I have designed a class which needs to be notified each time a node is added in this treeView, but I don't find it which event this class should subscribe This event should exist since, each time a node is added, the treeview is updated, no you're absolutely right, i should do that! Maybe, but it doesn't exist as far as I know. Nor do any of the interfaces implemented by the TreeView Nodes property raise an event when an item is added. As a workaround, why do you need to raise an event Aren't the nodes being added programmatically (they cannot be added directly through the TreeView control in the user interfac ...Show All

Open the MSI file with Orca, find the Control table in the left side table list.
