Check Whether Facebook User Likes App?
Mar 16, 2012
I've read several sources now but did not find a solution: I'm using Facebook C# SDK with ASP.net 4 and VB.net 2010. I have a Facebook Canvas application. I'm using Canvas Auth.Authorize and it works fine. Now I want to know whether the currently logged in user already likes my app. How could I do that?
'SignedRequest' does not seem to work because according to Facebook Documentation "This field is only present if your app is being loaded within a Page Tab". graph/user/likes is also not an option because I don't want to ask the user to grant access for my app to all his likes.But the Facebook Plugin is able to differ whether the current user likes my app or not, so I'm quite optimistic that there is a way which I just did not find yet.

I am using Microsoft visual basic 2010 for a asp.net site using c#.I am using the asp.net configuration for user registration. I have a comments form which I want to appear only if a user is logged in.I now there is a toolbox helper thing called Login View which does exactly what I want but as soon as I put a form inside the code won't compile because it cannot find the textbox fields.
I have the following in NewsArticle.aspx:
<asp:LoginView ID="LoginView1" runat="server">
<AnonymousTemplate>
<div class="postcomment">
[code]....
If I take the form out of asp:LoginView it works fine. Inside I get the following:
Error 2 The name 'txtTitle' does not exist in the current context NewsArticle.aspx.cs 59 53 Figmentville
Error 3 The name 'txtComment' does not exist in the current context NewsArticle.aspx.cs 59 68 Figmentville

What's a secure way to check a SQL for a user/pass? Directly connecting to the SQL is not secure at all as the user could see all of the sql data were he to decompile/deobfuscate the program.I'm thinking about using a php page to check, that way they only have access to the php page?

I need to create a spreadsheet of which kit is assigned to which person, within the company.
We have desktops & laptops, for the purpose of this post, we'll say desktops are named DESKTOP then a random 3 digit number (DESKTOP001, DESKTOP002 etc.) and laptops are named LAPTOP then a random 3 digit number (LAPTOP001, LAPTOP002 etc.)
I'm presuming the best way of checking which user uses each workstation would be to check who last logged in to it. doing this for ALL computers in a certain OU (lets say DESKTOP_OU for desktops and LAPTOP_OU for laptops in this example) (either with VB Script or PowerShell I would presume) and to export it to Excel.

I am writing an Excel addin to read/insert/update/delete SQL data. I am looking for tips or code samples to check if the user running the addin has select/insert/update/delete permissions. this would work on SQL 2000, 2005 and 2008. I have found the following which works for SQL 2005 (and likely 2008, though I have not tested).
Use AdventureWorks
Go
SELECT * FROM fn_my_permissions('Sales.vIndividualCustomer', 'OBJECT');
Go
[code]....

I am currently making a boggle game, I have done finished every aspect of it expect the spell check bit. I have been searching the internet fruitlessly, and have only found spellcheckers but none of the results allow the program to know the word is wrong. So what I want my program to do is after the user has pressed done or the timer runs out, it checks the items in listbox1 and if it is wrong then puts the item in listbox2.

I have a requirement that users be connected via the LAN for a small service I am writing. Simply check My.Computer.Network.IsAvailable isn't enough because that will detect any network (e.g. wifi). I need to check whether or the user is LAN connected (and can therefore connect to an Oracle DB)

My program opens 4 excel spreadsheets updating info. I update one at a time and then close it before opening the next one.I want to add code to my program to test if the file is already open, before trying to open it. Occasionally someone will have one of the files opened and it causes a crash. If I test to ensure it is not open, then I can avoid this.

I have two textboxes on the screen. They are used for startdate and enddate. If the user does not enter anything in the textboxes I pass nothing (VB.NET) to the webservice. When the webservice receive it on the other end it shows the value "#12:00:00 AM" which I think is the default for the datetime field. Anyway, now I do not want to pass this value to Stored procedure since it will not work. How can I check before sending values to sproc that the value is not the default datetime.
