Welcome to the All-In-One Code Framework! If you have any feedback,
Has anyone managed to get administration rights through the UAC without restarting the application or embedding a manifest file?
I'd like to write to some files that only administrators can modify, without relying to another elevated application. Is it possible to impersonate an administrator previously calling with some native API the UAC prompt?
I guess this is not possible and I'll have to use an external tool with elevated rights, but I'm asking just in case.
EDIT: I know there are some other similar questions around, but since they do not cover the topic of impersonation (as fas as I've seen), nor some possible native call to the UAC prompt I decided to give a new thread a go...
Is there any way of restarting a single instance application, which is deployed via clickonce?
View 1 RepliesI developed a chat application with an attendant chat server. Everything is working fine. The issue now is the fact that whenever the chat server goes down (for instance, the server system shuts down as a result of power failure or some other problem), by the time the server system come back on, the chat server would have to be restarted manually.
I believe (and I know) it is more appropriate for the chat server application to restart itself when the computer comes back on (and of course regardless of who is logged in and of course, even before anyone logs in). I have a batch file that executes the chat server. My attempt was to create a windows service that start automatically and runs this batch file using a Network Service account on the server system. Although, I'm having a hard time with this (temporarily), I would love to ask if there are any alternatives to using a windows service.

View 1 Repliesi have a simple application which can create/update/delete/search records using Access database. If i add a record, save it, then close the application and run it again and search for that record, it appears. However, when i write some code to my application, nothing to do with the search function, and i run the application the record is not found.

View 6 RepliesI've made an application that is meant to be run without administrator privileges in Windows Vista / 7, because UAC disables drag and drop events from lower applications into higher ones, because they could pass bad information into the high trust ones [for example, standard explorer cannot pass files into my program that a user might run in administrator].

View 5 RepliesI've a website that puts info into a mySQL database and a windows service (written in VB.Net) that polls the db and actions what's in there.However, occasionally it stalls and rather than having to RDP into the server, I want superusers to click on a button to restart the service.I can get the button to say, do a directory listing of c: output to a test file so the whole 'getting a command to execute on a remote server' issue works. However, I can't restart services.I assume this is a security thing (although it has full rights to c: I thought I'd sussed that already).The website runs under the normal IUSR_user so am I doing something really stupid or can someone explain how to get the service to be restarted ?
View 4 RepliesI want to know how can I restart a terminated thread?I have a 3 buttons (Button1: Start/Resume, Button2: Pause, Button3: Cancel) code 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.
