I have created an Office addin and windows installer application for it.
According to this article, addins dll'a are copied to directory like this C:\Users\Robin\AppData\Local\assembly\dl3\VBJZ5WH8.6NJ\HRZA3JXN.LVG\b0520efe\3a5b99ef_2e21cb01\GoldMail Outlook Add-In.DLL. I wish to remove those copied files during the uninstall process. Could sb please tell me how to get the full path to those copied files in C:\Users\Robin\AppData\Local\assembly\dl3\ in my installer application (actually in uninstall)? Is it saved in registry or in any other location? I have noticed, it even happens, the files are copied multiple times. Any help would be appreciated, greetings.

My VStudio is 2019 Community, the application is an old VB Windows/Forms app being brought forward from .Net-3.5-ish to .Net-5.
Under .Net-4.8 or earlier, using the namespace System.Deployment.Application, one could access ApplicationDeployment.DataDirectory to locate that artificially-generated directory in \Users\Username\AppData\Local\Apps\2.0\... that a 1-click installation would create and populate with data files from the Project Build/Publish.
Under .Net-5, I believe that particular set of functions has been taken out - yet the ClickOnce installer still places Data files there. How do I programmatically locate that directory? The Application Path can be located from System.AppContext.BaseDirectory, but that doesn't help in locating the data.
This app, an old bit of VB code, has a large number of application data files that need to be installed along with the code. As there are more than 40 of them, we've kept them in their own \Data directory, which is included in the Project, is under Git control to keep their versions aligned with their code...
In an uninstalled app, we could keep this \Data directory adjacent to the executable, and find it easily at runtime: but with a ClickOnce installed app, that falls apart. In the Publish configuration, all the data files are identified, with Group=Required, Publish Status=DataFile.
Can I either:
Easily configure the 1-click installer to place our \Data directory and its contents into one of the standard \Local\Appname or \Roaming\Appname directories that seem to also get created, but left empty? Those can easily be located at runtime.
Easily construct at runtime the path to that obscure data directory that 1-click normally creates and uses for data?
Cheers, and Thanks! Bob
I am creating an Uninstall Tool for my application. The (.exe) is located within one of the folders that needs to be deleted.
When I try:
IO.Directory.Delete("C:\Program Files\application_folder", True)
I get an error that the program is denied because it cannot find the specified path.
Essentially, I am asking is there code or some software approach to handling how to delete the Uninstall (.exe) when it is in the folder I am deleting.
Thanks in advance!
Glad to see this site, Thanks guys for being active. :)
I have a problem in Visual Studio 2010/VB.Net
I have windows form in Visual Basic, I deployed the software(form) to one installer
Now I want to open My PDF file( i-e: Specific) with Button_Click_Event
I know that:
Process.Start("MyPDF.pdf")
But I dont know if user install my software in his PC so may be he install the software in C D or other directory, and also I dont know How to include PDF file in my project :)
Please suggest for me, I am searching this every where but failed so pl help me
Use Add->Existing Item on your Project. Then add the PDF File to your Project.
Afterwards you have to set the Properties of the newly added file to the following:
Now the file will be added to your "Output" Directory after you build your Project.
Now use your Process.Start("MyPDF.pdf") call. It will open up, as it resides in the same directory.
This is rather easy:
Simply include the file by dragging it to your project folder and in its options, tell it to copy to the build directory.
Thereafter, find the path through the my.application methods.
Build a correct path from that and launch it via process.start
I haven an installer which must run with elevated admin rights if UAC is enabled. This works fine. When I upgrade the app (using the MajorUpgrade element) the app gets uninstalled and reinstalled correcly.
During runtime the app attempts to change some files in the program files folder which places copies them items in the users virtualstore. These do not get removed during uninstall.
During the upgrade/reinstall process, is there a correct way to delete the application file copies, for all users, in the VirtualStore?
Files placed into a virtual store are, by definition of who wrote them and when, per-user data files. Such files typically should not be removed during uninstallation. If the files in question are not actually per-user data files, the application that caused them to be written should be fixed to write to a proper location, update them in a controlled fashion, or even not write them at all.
I am using Scott Mitchell's textBox Characters and Words counter control, i downloaded it from the website https://web.archive.org/web/20211020202742/https://www.4guysfromrolla.com/ and unzipped it to my desktop. then in VWD Express 2008, i created a new tab in the Toolbox, i chose the *.dll from the unzipped folder, i used the control, all is fine (try it, i recommend it) but when i backed up my code, copied the site, and tried to run it on another computer, i got a bunch of error all indicating that its looking for the dll file on my desktop, but when i checked under my bin folder in my website directory, the dll is there...
Help Plz...
If you view the properties of the reference you'll probably find that the path to the reference is incorrect.
I have often found that the quickest way of fixing the problem is to open the project file with notepad and correct the path to the reference.
