jQuery Ajax with Json call to WCF service pass-through to WCF service

阅读更多关于 jQuery Ajax with Json call to WCF service pass-through to WCF service

问题 I'm attempting to use jQuery Ajax call with Json to call a webservice which is a pass-through and calls another webservice. This works if I don't use ajax, works as an ajax call to the backend service directly, but does not work as ajax call to pass-through service. My question is how do I get an ajax to pass-through webservice to webservice to work? This is the code I have so far: [ServiceContract] public interface IService1 { [OperationContract] [WebInvoke(Method = "POST", BodyStyle =

问题 I'm putting this specific item in here because I ended up somewhere completely different on StackOverflow, and don't see this specific answer anywhere. I was getting an "ODBC error" back from running an MS Access report using an SQL passthrough query, and dao.Errors contained "Operation is not supported for this type of object" 回答1: This error is also returned from an SQL pass through query when the query throws an error because a sub query return multiple values In my case, the stored

Use function call in passthrough query?

阅读更多关于 Use function call in passthrough query?

问题 I have a passthrough query in an Access 2010 application, which I'm using to call a stored procedure on a SQL Server backend. The stored procedure takes a parameter that I need to make dynamic. The problem is this: Execute spMyProc 'userName' works as expected. Execute spMyProc getUserName() generates a "syntax error at ')'" message. Is it possible to use a function as a parameter in a pass-through query? Also, I should note that I'm migrating a complex Access application to SQL server, and I

Pass-through authentication not working. IIS 7

阅读更多关于 Pass-through authentication not working. IIS 7

问题 On IIS 7 I set up an application called "XYZ", and an application pool for it. I set the identity of this application pool to a custom user, let's call it "Mario". Mario has NTFS access to the folder/files in which XYZ points to (remote share). In the XYZ authentication settings, only windows authentication is enabled: In the providers for windows authentication, only NTLM is active: Physical path credentials for XYZ are set to application user / pass-through: So the problem is, when I go to

Is there a simple way to pass specific named PowerShell parameters through directly to a called function?

阅读更多关于 Is there a simple way to pass specific *named* PowerShell parameters through directly to a called function?

问题 I am sure I read somewhere that there is an easy way to pass named parameters from a calling function to a called function without explicitly naming and specifying each parameter. This is more than just reusing the position; I'm interested in the case where the name of the passed parameters is the same in some cases, but not in others. I also think there is a way that is not dependent on position. function called-func { param([string]$foo, [string]$baz, [string]$bar) write-debug $baz write

Squid+iptables: how do i allow https to pass-through and bypassing Squid?

阅读更多关于 Squid+iptables: how do i allow https to pass-through and bypassing Squid?

Basically started with Squid and iptables today (google is your friend). This stuff is going to be the death of me. I have Squid3 setup on Ubuntu 9.04 server as Transparent Proxy. It works sweetly when i use the proxy-box as my default gateway etc. The iptable rules for this setup was part of the tutorial. :P I can unfortunately not access https sites (such as Gmail or anything on port 443 basically). This is because Squid dont like what it cannot cache, which in this case is the https traffic. I would like to add an iptable rule so that i can basically access https sites and use Skype.

问题 I am working on an Win32 C++ application where I want to ignore the mouse events and let is pass through to the window beneath my window. Basically the window below mine will handle the mouse event. I would prefer not to send the mouse message using SendMessage to the window beneath mine or use SetCapture. Is there a way basically to ignore the mouse event and let it pass through with Windows APIs or with styles? Note that my window is not transparent. Thanks in advance for the help. 回答1: So

阅读更多关于 What character sanitation do I need for an MS Access Pass Through Query to SQL Server

I am attempting to interface MS Access with SQL Server and I want to make sure I am not vulnerable to SQL Injection attacks. I have seen suggestions to use ADO to create a paramaterized version of the queries, but I wanted to learn how to sanitize my input with a DAO pass through. At the moment I am escaping single quotations and backslashes. Are there any standard SQL Server injection sanitation methods in VBA?

Maximum Length of a SQL Query in Microsoft Access 2010?

阅读更多关于 Maximum Length of a SQL Query in Microsoft Access 2010?

Attempting to copy/paste a 159KB TSQL query into Microsoft Access 2010 passthrough query editor (to a Microsoft SQL Server 2008 backend). This produces pop-up error, "The text is too long to be edited". What is the maximum length of a query in Microsoft Access 2010? Dzoki The help file says that the maximum number of characters in a SQL statement is approximately 64,000. It doesn't mention any difference between pass through queries and other queries, so in the absence of any specific documentation I'm assuming that this also applies to pass through queries. Looking for this myself and found
