I have developed an application in VS 2008 that generates crystal report.When I export the report to pdf,the application gets hang.The problem occurs since I can not create temp files in the temp folder i.e. %tmp%.The security level of windows 7 is high and it does not permits the application to create file.Can I alter the permissions in windows 7 using vb.net ?
View 10 RepliesI have a link on a VB.net aspx page that needs to open a folder in a subdirectory of a web site and provide read and write permissions so that files can be copied into and read from as well as deleted. ONLY from this folder.I have this funtionality working on a dev and demo PC but they are both on my domain. Clicking the link opens Windows Explorer and I can copy /cut & Paste, etc.The public/production PC is on the LAN, but not part of the domain. I know there are ways to allow folder read/write permissions on a public server like this but I am not too sure on the safest way to do this. The upside, the only users that need to have read/write/delete access are employees. Forms Authentication, ASP Membership directs non-employees to other pages within the site. Likewise, the membership directs employees to an admin section of the site.

I'm trying to write a ClickOnce ap that will connect to a web database and download the data into a collection that will be written into a local database. This will allow the user to update the data while online but use the program while offline. I see it as a hybrid ap using both Windows forms and asp sql calls.
View 7 RepliesI have a user of one of my programs reporting that they get an "access to the path...is denied" error during this section of [code]He's using Windows 7 x64 with UAC turned on. The location of "FilePath" is a subdirectory inside Program Files (x86) in this case.I tried to reproduce the error on my Windows 7 x64 system by enabling UAC (I usually have it off) but the program worked fine. However, in my case, "FilePath" is not in a protected system folder like Program Files (where write permissions are not given to normal users without admin elevation).So I tried to recreate this situation on one of my Vista x86 Virtual PCs where the "FilePath" would be inside Program Files. However, my program again worked fine. It had no problems writing to the Program Files folder with a normal user account, UAC turned on and no elevated permissions required.
Thus, I am confused. Why does it work for me and not for him? I want to try an x64 virtual machine but I can't with the software I have (Virtual PC doesn't support x64 guest OSs, VirtualBox won't run the software that my program interacts with). So maybe you guys can help me instead. Are the write permissions for the Program Files (x86) folder different between x86 and x64, or maybe even Vista and 7?

View 1 RepliesIf I adjust permissions using the Security.Accesscontrol.DirectorySecurity on a directory, how can I make it so that subfolders automatically inherit the new permissions?
Brief overview of the situation is that my neighbors can't connect their Vista laptop to a shared folder on their computer running XP Home. They're getting access errors which I believe is because of the rights set on the folder. The problem is that XP Home won't let you adjust that and they're not upgrading.
I'm able to add the Everyone user to the directory I specify. But if I drag a new folder in or create a new folder, it does not have the Everyone user. Is there something I'm missing in this class that will let subfolders and files inherit the permissions?
I developed an assistance programme for an online game, and, in response to the users demands, I developed a secondary programme that downloads a zip file from a webpage hosted in a free Geocities server with the latest update for the programme and applies it. With the WinXP users it has worked perfectly, but with the Vista users, I've had a few cases where the update programme wasn't able to download the update, although everything worked fine with other uses.
View 2 RepliesI am wanting to update our current windows forms security to something a lot more flexible. At the moment we have a single column in thew users table which is named 'Access_Level', this field holds an int value (1 to 4) which is then use to determine users access to certain areas of the application. This worked fine when the system was small, but the system is growing rapidly now so I think it is a good time to update the user access and possibly introduce roles.

I've been struggling with this problem in VB.net for a while: whenever I try to access the My Documents, My video's or simular in Windows 7, I get an access denied error. The program that uses this code is a file-backup application, so it's important it can access everything. The app has admin rights, using this line:requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
To confirm, I also get a nice UAC popup when starting.The app accesses the files twice. Once to calculate the file size, and once to actually copy the files. Here is the file-size calculation code (that I found online:) Function GetFolderSize(ByVal DirPath As String, ByVal includeSubFolders As Boolean) As Long

I am trying to extend an application to to write the details from textboxes on a invoice form to an xml file.I have created 3 methods for my invoice class which will open the invoice xml document, write to it, and close it.The open Invoice method creates and invoice.xml file and writes a start tag named invoices.
The WriteInvoice method writes an invoice element for the invoice with attribute named customerName and three child elements named ordertotal, discounTotal and Invoice total. These values are taken from the textboxes form the form.
The CloseInvoice writes the end tag for the root element(invoices) and closes the file.
I have wriiten code for these methods but can only get the open invoice method to work.
My code for the 3 methods is shown below:
