My app needs to delete and rewrite a text file called events.txt
now it used to work but now when i run the app it shows an error due not being to access the file in the "Program FIles (x86)/MyApp/" folder?
making a program that will have access privileges (for example, some users can add some kind of information but not other, or visualize some pages but not others). I want to make this access control by relating each button in my project and making it enabled or not to the users. For example, if the user can add only information A, the button "Add New A" will be enabled, but not "Add New B". For doing this, as my project have many buttons, i thought about a sub form relating every single button of every form in my project
View 13 RepliesI'm using VS 2010, and I did a project using VB and a database in Access. The problem is that when I try to put that "application" on other computers, sometimes, is not working. I thought it can be because on these computers they don't have access, but on one computer, is running another app which is using Access and there is no Access installed. How can I check if my application requires Access to be installed or not?
Here is a example of how I did the connection:
Public AccessOLEDBConnString= "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & myfullpath & ";Jet OLEDB:Database Password=password"
Function getConnection() As OleDb.OleDbConnection
[CODE]...
And when I want to have access at the data I'm doing like this:
dim conn as Oledb.OledbConnection
dim sql as string
dim ds as Dataset

I am getting the above error when I attempt to run setup.exe as a non-administrator on Windows XP (sp3). This is for an application I created, and I would like to know what permissions the users need to install the application and updates. I am trying to understand the security issues when installing a vb.net desktop application, the .NET framework, and other resources such as the visual studio crystal reports engine. Any good resource which explains how this works for different operating systems and privilege levels?
View 6 RepliesOne of the client requirements is that the server generate files and store them on a special folder. This files created can not be modified by users or deleted.So the only way I thought is to generate this files with elevated privileges so a normal user can't delete or modify them.But the question is how can I generate a file with this privileges that normal users can interact with this files... only download from server.I use this code to generate the file...

I'm trying to use a java servlet in a 3rd party tool's web interface (CA service desk) to invoke it's download file functionality using a webclient in vb.net. The trouble is the text stream from response is markup and not the acutual text file stream.
It's like the page is redirecting to another page which actually presents the file for downloading. I have no idea what the redirected page URL is.
Is there a way I can process this redirected page in order to get at the download using a system.net.webclient?

Im am currently coding an application for auto updating ccleaner. Everything worked well until I enabled UAC.. I am using this project: [URL] to schedule the updating process, but when uac is enabled I get every time a message if I would let ccleaner installer make changes to my computer. The auto updating process must be done silently without bugging the user with prompts of uac.

I would like to save let's say "HKLM/SOFTWARE" into file using API. First I open the key using RegOpenKeyEx. This works fine as I see that the ReturnPointer is different from zero and differs also when I switch from "SOFTWARE" to other subkey, therefore I assume no problem there.The problem comes when I want to save into the file. It creates only a blank file with return code of 1314. I have googled for this, but only found that this error means that application has no privilege to perform the action and I need to setup "SeRestorePrivilege" & "SeBackupPrivilege" property somehow. I haven't been able to find a good VB.NET example for this and as I am very weak with APIs I wasn't able to construct one of my own, therefore I would like to ask you for advice on this.Could you please help me on how to set the privileges so that I can export/import registry?

A few months back I wrote a VB.net console application to migrate a group of about 100+ printers and the 1800+ users that use them from some old HP print appliances to a mixed Print Server and Direct to IP Printing solutions. The application uses a database to compare installed printers and remove old/invalid shares and remap to the new Win2K3 based print server OR create a TCPIP printer port and install the driver for direct to IP printing.
It worked really well, but users needed power user rights to create the TCPIP printer port. For the main campus this wasn't an issue, but the smaller remote sites need a solution that allows the app to be run by users without power user rights.
My solution was to take the "CreatePrinterIPPort" function and put it into it's own wrapper app and then call it as needed from the main app using a hard coded local admin account for the purpose, but I'm running into issues when spawning the createport app. If I run the app standalone it creates the port with no issue, but when I run it in my test app to spawn the createport using the CreateProcessWithLogon API the port creation fails with an "access denied" error. I'm limited to using .net 1.1 as 2.0 isn't in our environment throughly and I was told it wouldn't be pushed just for this app.
