View 1 RepliesI've built a VSTO add-in for Microsoft Word and deployed to a webserver. Installation goes off without a hitch. When I create an updated version of the application and redeploy it to the webserver, the add-in correctly detects that there's a new version and attempts to update it. This is where I'm running into the following error (the "xxx" indicates that I had to censor something):url...The customization cannot be installed because another version is currently installed and cannot be upgraded from this location. To install this version of the customization,first use Add or Remove Programs to uninstall this program: xxx. Then install the new customization from the following location: url...This appears to me as if I left a local reference of some sort in my Project, but I can't find anything of the sort. The only reference to this file is within the xxx.vbproj.FileListAbsolute.txt file that's generated in the bin/Debug folder.Not sure if this is also a clue, but I'm seeing Registry Keys added referencing this as the location of the VSTO Project Manifest.
View 1 Replies1. Just looking for some general help on how to auto update my application via a file location path (e.g. I have a HTML file containing the current file version and the .exe file to download)
What I need is to read in the HTML file version - DONE Check file version vs HTML file stream input - DONE Replace current .exe file with new .exe file - HAVING ISSUES WITH THIS
I know I have to close the application and then replace the old exe file with the new exe file then restart the application but looking for the best/safest way this can be done
2. Basically what I want is during my Splash screen which runs for 5 seconds I want to check if a network drive is mapped.

I have developed a desktop program, works on network.I am trying to create a setup for this program. But in the domain, there is a policy about installing softwares.I mean its not allowed to install any program for users.How can i achive this goal that: i want my software to update from a specific location on the network without asking to users automatically.
View 1 RepliesI want to make my applications to have a self update function. My applications have only one file, the main .exe. For updating, I want to use the best way: the program download it's new version overwriting itself; and on next start the program will be the updated version. I tried to use the ShadowCopyFiles, but all the times the main file is locked, so cannot overwrite it (or delete or anything). I found many examples in the internet like this:

I have written an application for a customer, and the application is run in various locations around the world. The company carefully controls the release of the software to the various buildings where it is being used, and because of this, I have made use of the "Check for updates" feature. The problem I am faced with, is that the folks using this software more often than not answers "NO" when prompted to download and install the latest version of the application. This is unacceptable and ultimately, we'll need to go in and have them manually install the software.
We don't publish updates to the software w/o meaning for them to be necessary, and I find it hard to believe that Microsoft doesn't recognize this sort of thing as being needed when they designed the update procedures. Alas, this seems to be the case.
I would like to implement update to my applications but not in the automated fashion. I would like the user to check for update, through version control in my database, and if there is a newer version, it will automatically shutdown the user's application and run the update (copy and replace files in the users application folder). After the update, it would restart the application for use. I was thinking in creating a .msi for creating and replacing files, still don't know how to create it! My main concern is to be able to implement a proven and correct .Net method for Updating applications. A best practice for deploying and executing updates to my applications.

View 6 RepliesI have a stand alone application "test.exe" on a Windows 7 operating system.I have an application "test.exe" made in Visual basic 8.0.I have an "Auto Update" function . Call this function from "test.exe". In the first line in "test.exe".This function does the following:

1a. Removed all *. old
1b. Rename test.exe to test.old
1c. dowload new test.exe

I Created the setup for my vb.Net appliaction and installed it on the client systems. The application uses MS Access as the database. So i manually added the file to Setup project under its application directory.

Welcome to the All-In-One Code Framework! If you have any feedback,
Is it possible to use the strategy to force an application to update completely every s often to prevent piracy.I mean somenone manage to crack our click once application and make some modification.but inside the application there is some part of the code that make mandatory to update it.in each update all the application is replaced completely in this way the application on the user computer is a clean one and not the cracked one so the checks for seraching for serials numbers are reinstaed is it possibile to use this as technique to prevent piracy?
View 2 RepliesI'm working on a project at the moment that relies heavily on the configuration information stored in My.Settings. The problem is, whenever I update the software, it resets the settings. I'm thinking it may have something to do with the way I update the software. I make my changes to the program, then up the version of the application and its setup project (also creating a new Product Code). Afterward, I just run the new install to update the application.
View 4 RepliesI know there are many posts about updating an application with UAC turned on. We have a huge application and our own update program for updating that. We don't want to use the UserAppData area to install our exes. We do mostly custom programming so updates are a part of like for us. My question is: If we get our update program digitally signed can the standard user with UAC turned on accept those changes without administrator privileges and can that be done to a VB6 executable.
View 8 RepliesI need to update a table when my application closes. This is with the user name of the person exiting the app.
This works fine when the user closes the form from the main menu exit button where I have written code to update the table. However if a user exits from another form the main form is not closed (as I thought it would be) and the code that updates the table consequently does not run.
I have tried entering on other forms under the FormClosing event but this does not seem to run if they click the X in the corner of the form.
How can I get that code to run when a user exits in some other way.
I was wondering if there is a way to update Windows Vista via a Vb .Net application.
I wanted to use Vista's WUSA.EXE, but it seems that it is only able to do specific updates in a specific location, not all updates.

I have been asked if its possible for an application that sits on a network folder for multiple users and check online to see if there is a newer version. If there is prompt the user to download it and load the new version.
View 5 RepliesI have implemented the filestream feature of SQL Server 2008 in a VB.Net application. I can insert files, and then retrieve/view them just fine. However, I have huge problems trying to update a file. Eg. The user selects a file from the grid which I execute via process.start. If that file is a .txt file, the user may choose to edit it. In case that happens, I need to save the changed file back to the database. So far I have failed to do that.
What I do, is take the retrieved file, copy it (cause i got some errors about it being used), and then Process.Start it. After that, via .NET filestream, I convert the file to bytes and try to update the record. SQL Profiler and a manual SELECT on the varbinary(max) column tell me that the file is updated properly, but the very next try to retrieve it I get an unchanged file.
After that I also tried to update the file by changing its File-System Version, but the file still wouldn't seem to update. Does Anyone have a code sample of how I can achieve this operation? Like 500 sites on the internet have examples of how to Insert And Retrieve the file, but not a single example on how to update. This is how my second attempt of trying to update the file via the filesystem looks like. The code for inserting/retrieving is very similar and it works properly. [Code]
I have a csv file that needs to be automatically updated on a daily basis. I am writing a vb.net app to accomplish this. However, Im having issues with the entire process.I need to be able to read in a csv file, manipulate the data and then update the existing file. I have dabbled with using the Excel objects but I need some assistance.
View 6 RepliesI've deployed an application inside a corporate network and I want the update process to require less attention from users. Giving them a choice to update is not a porogative.I've written code to detect when new updates are available automatically rather than letting ClickOnce check on application start. I'm wondering if its necessary to restart the app after the update has completed. Currently I invoke at the end of my update script:Application.Restart()
But what if (to make the update process more transparent for the user), I performed a 'silent' update in the background on a separate thread, and then displayed an icon prompting the user to restart the app to apply the changes? Would it work this way?
Furthermore, if I ran my custom InstallUpdate() process on a timer, say every 2 hours, would ClickOnce be happy to continue to update for every new version that was released even thought the user has not restarted (and I'm expecting the updates only to apply once the user restarts the app)?
I have an application that opens up Excel, reads some information, then closes Excel. I developed this application using Microsoft Office XP 2007. A few weeks ago, my company upgraded to Microsoft Office 2010. The applications still works fine, but I can not compile in VS 2008 anymore. I get the error message: "Error 3 'Application' is ambiguous in the namespace 'Microsoft.Office.Interop.Excel'." I have updated my COM reference to Microsoft Office 14.0 Object Library, but the same message appears. [code]Obviously there is a bunch of stuff under this, but this shows where the errors are.I am unable to fix a bug in the program because I can not even compile it without error.
View 3 RepliesI have a problem with Firefox and Silverlight. I have a silverlight application (with version-number 1.0.0.0) on my website. Now I have modified the silverlight application(version-number is now 1.0.0.1) and replaced the old file on the server with my new application.
The Internet Explore loads the new application correctly. But unfortunally the Firefox 4 still loads the old Silverlight application.
I found there is something related "OnceClick"[code]...
but how to use it?? Got better solution like tray icon prompt the new version available. then prompt user permission for update~
if user accept to update, it will download from server and install and restart application.
