i am trying to create a directory in drive C: (at a win7 target machine) with Directory.CreateDirectory but so far no luck.
I believe the problem has to do something with permissions-security... So here i am..
How can i create a directory in drive C?

You need to run your application in elevated mode (via UAC). How this can be done is shown in the above StackOverflow thread:
UAC, Vista and C# - Programatically requesting elevation
Before executing the code to switch in elevated mode you should do a check if you application is running on Vista, Windows 7 or above.

You should not use the root of C for an ordinary application. If you're just using it because you think it's a folder you can count on, use AppData or Temp instead. If this is not an ordinary application, but is instead an administrative application, then put a manifest on it requesting it elevate (requireAdministrator) so that it can gain access to the areas of the hard drive and registry protected by UAC.

DirectoryInfo dir = new DirectoryInfo(#"c:\MyDir");
dir.Create();
hope this will help u...

Unable to add excel add-in for all users

We have an application which shows up as an Excel ribbon.
We have installed the application in our test environment through administrator login. We are trying to make a per machine installation.(Please note that in production environment, the installation will be through system account).
When we login as user to the same PC, we don't see the excel addin in the Excel ribbons. We don't see the addins anywhere in the list of addins as well.
We have tried using Active setup,Userstat,setting the values of properties as ALLUSERS=1, RegisterForAllUsers= True, InstallScope= perMachine, InstallAllUsers = Everyone, RunActionsAsInvoker = True . Also the privileges has been changed from user to admin in all the cutom actions and in manifest file as well. All these changes where made as we understood that the application used to package is Addin express and so the msi creation with privileges as admin is possible.
Unfortunately none of these changes seems to help us.
What we would need is an msi which we can install on per machine basis.
From the situation mentioned in the question, we had tried a lot of options and finally following approach works for us:-
Create a package which would place a powershell shortcut in the startup folder.
The shortcut would in turn call or execute a powershell script.
The powershell script would
1. check if the registry key for that particular add-in is available in HKCU.
We had our registry key as "HKCU\Software\Manufacturer Name\Product Name" which in turn had a string value "Installed".
If the registry key is not available for the user, then install the package with tranform.
3.If the registry is already available, then script doesn't make any change.
The package is installed as an Admin and once the user logs in, then automatically the cmd file is executed and the add-in is installed.
Since this was the first version of the product, we didn't have to handle version compatibility.

Running a program at login as admin

I have a program I wrote in Visual Basic Express 2013 to put a classification banner at the top of the screen. I set up a scheduled task using ngen.exe which makes it run at login. The problem is that it doesn't run as admin so any non-privileged user can kill the task.
This program is to replace another program called Netbanner because there are a few issues with Netbanner. The program I wrote resolves all of these issues except for the admin issue. Netbanner is implemented exactly the same way (ngen.exe) but it won't let a non-privileged user kill the task.
I don't know if it is something in the program itself or I missed something in the deployment process.
This is the command used to deploy Netbanner which I duplicated to deploy mine:
C:\Windows\Microsoft.NET\Framework\v4.0.30319\ngen.exe install "C:\Program Files\Microsoft\NetBanner\NetBanner.exe"
Also, these are the files in C:\Program Files\Microsoft\NetBanner:
NetBanner.exe
NetBanner.InstallState
NetBanner.pdb
NetBannerSchTask.xml
Any ideas?
Thanks.
You could try to go into the properties->Compatibility->Run this program as an administrator for the application.
Alternatively, you could do the same thing for a batch file that you can schedule to run on startup.

SSIS Execute Process Task Can't Find executable

I am using the 7zip standalone .exe to unzip a file. I am using the Execute Process task for this. I have tested this over and over again on multiple machines and I know it works (at least in debug mode/visual studio). I have uploaded this package the server. I have created a job that calls said package from the Package Store. The package is not able to find the .exe no matter where I put it.
My first thought was to put the .exe on the C:\ drive, which failed. I have also failed in my attempts to place the .exe on a network location that the account the package is running under has full control over.
Basically, has anybody else had issues getting the Execute Process Task to find an executable when the package is uploaded to the server?
The error message is
Can't find 7za.exe in directory C:\7zip
I'll risk a downvote for being wrong, but I believe you have a permission issue.
You say it runs fine on other servers from BIDS, try it without BIDS. Call it from a command-line on a box that it works on.
dtexec.exe /file C:\HereComesTheUnzipper.dtsx
If that works, then repeat the step on the troublesome server. RDC into the box and try again
dtexec.exe /ser localhost /sq HereComesTheUnzipper
If that still works, then you are looking at an issue with the job. What account is the SQL Agent service running as? Is the SSIS job step running as a particular set of credentials? If so, is it a SQL Server login (which wouldn't map to anything on the physical box)? Regardless of what your answer is, the resolution will be to ensure the account has access to
7z.exe
whatever scratch area 7zip may use while unpacking files (I assume %temp%)
the output folder (C:\bin\7z.exe -e e:\data\MyThing.7z)

execute registry script from vb.net

I am trying to work for an application where i need to embed registry code in my program. Basically this is a Windows App.
My registry code is
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\DesktopBackground\Shell]
"icon"=""
"Position"="Bottom"
[HKEY_CLASSES_ROOT\DesktopBackground\Shell]
#="system.exe -L"
This code is stored in a registry file. All i need to do is invoke this script on an event handler say button_click.
Options i have is write this code as a string and execute this string.. or simply have a collection of *.reg files which i may execute on button_click.
I understand my app requires UAC, and i would be giving that permission for my app in App Manifest.
Can anyone pls suggest me how to execute registry file (.reg) stored placed in a folder
Use Process.Start with a ProcessStart.UseShellExecute = True

Microsoft Office Excel cannot access the file

I have create Office Excel application in my machine(XP). and i have placed the application in windows server 2008 giving the following error.
Microsoft Office Excel cannot access the file '\server\Input.xls'. There are several possible reasons:
The file name or path does not exist.
The file is being used by another program.
The workbook you are trying to save has the same name as a currently open workbook.
both client and server systems installed office 2007 and added reference microsoftexcellibrary 12.0
created assembly for the application and calling the code from the form.
I was getting the exact same error, although in my case I was trying to run (from Tidal Enterprise Scheduler) a .NET app that used microsoft.interop.excel.
The answer is already in stackoverflow:
[Microsoft Office Excel cannot access the file 'c:\inetpub\wwwroot\Timesheet\App_Data\Template.xlsx'.
I'll re-list the steps from that link:
Create directory “C:\Windows\SysWOW64\config\systemprofile\Desktop” (for 64 bit Windows) or “C:\Windows\System32\config\systemprofile\Desktop” (for 32 bit Windows)
Set full control permissions on Desktop directory above (for example in Win7 & IIS 7 & DefaultAppPool set permissions for user “IIS AppPool\DefaultAppPool”)
Of course, if you're running a scheduled task rather than WebApp, you'll need to make sure the service account you're using has permissions on that folder.
I had the same error when trying to save to:
C:\test.xlsx
When attempting to save to the root directory, it seemed to cause problems. Changing my path to:
C:\MyExcelTests\test.xlsx
Worked fine
I would make sure no Excel processes are running on the machine before you run this application, that should cover the last point.
The first point looks the most likely issue, the path looks like a partial path or an incorrect UNC path. Try putting the full path to the spreadsheet 'C:\server\input.xls' and see if that works.
To stop the middle point, in the workbook.open command you can specify to open as read-only, this will make sure the application can red the file even if it is locked open by another user.
