  • Outlook VBA script - find and replace text with image

    - by user2530616
    I have a e-commerce store. When I get a sale, I receive an order confirmation email which contains the name of the product sold. When the email comes through, I would like to run a script that replaces the product name eg. "red widget", with a picture of that product. Is that possible? I have found a similar code to replace text (set of numbers in this case) with a link, but I need it to replace with a picture instead. Option Explicit Sub InsertHyperLink(MyMail As MailItem) Dim body As String, re As Object, match As Variant body = MyMail.body Set re = CreateObject("vbscript.regexp") re.Pattern = "#[0-9][0-9][0-9][0-9][0-9][0-9]" For Each match In re.Execute(body) body = Replace(body, match.Value, "http://example.com/bug.html?id=" & Right(match.Value, 6), 1, -1, vbTextCompare) Next MyMail.body = body MyMail.Save End Sub example mail Order Confirmation Thanks for shopping with us today! ------------------------------------------------------ Order Number: 2209 Date Ordered: Friday 28 June, 2013 Products ------------------------------------------------------ 1 x red widget = $5.00 ------------------------------------------------------ Total: $0.00 Delivery Address xxx search text: "red widget" replace picture: redwidget.jpg

  • Problem with building OpenCV for Python 2.6

    - by si14
    I've just downloaded OpenCV's trunk and now I'm trying to build it with MinGW. I read the manual and get .dll's compiled, but that's all - "interfaces/python" contains only some .i and .cmake files. How can I really get new python interface? Where I can find new cv.pyd/libcv.dll.a (because a compiled version from official site crashes sometimes and I saw this bug as "fixed" in Trac)?

    I am using a UISearchDisplayController and SearchBar initialised from a nib. when the search is being run I get a flash of a small circle what looks like a "bullet" in the top left corner of the search results. [See attached screenshot] It occurs in the simulator and on the device sporadically I have looked through my nib and I am not adding any stray views and was wondering if anyone else had this issue or knows how to get rid of it? thanks @interface SearchTabViewController : UITableViewController

  • Enumerating and using wmp visualizers

    - by monoceres
    Hi! I want to use the systems available windows media player visualizers in my app. Apperently visualizers expose an IWMPEffects interface to the world. My question is how do I enumerate and create instances to the available visualizers on my system? Probably it's just a process of getting the cslid of the visualizers and then create the instance with CoCreateInstance. However I have no idea how to get these clsid's! Thanks!

  • Installed Programs/Computer Info for Web Application

    - by Ryan Gyure
    I'm currently developing a support system for a university. The system is written in PHP and I would like to be able to get a current list of software and basic computer information on a computer. Basically when one of the faculty or staff creates a ticket from our web interface, I would like to have a Java Applet or similar that could be run and would return the information to the help desk PHP script. Does something like this exist?

  • Why limit WCF ServiceContracts to 10-20 OperationContracts?

    - by Gary B
    I've seen recommendations (Juval Lowy, et al) that a service contract should have "no more than 20 members...twelve is probably the practical limit". Why? It seems that if you wish to provide a service as the interface to a relatively large db (50-100 tables) you're going to go way past that in just CRUD alone. I've worked with plenty of other services that provided hundreds of 'OperationContracts'...is there something peculiar about WCF? Is there something I'm missing here?

  • NSMutableArray with only a particular type of objects

    - by Leo
    Hello, is it possible to specify that a NSMutableArray can only contain a certain type of objects. For example, if I want to store only this kind of objects : @interface MyObject : NSObject { UInt8 value; } In order to be able to use the instance variable like this : - (void)myMethod:(NSMutableArray *)myArray{ for (id myObject in myArray){ [self otherMethod:myObject.value]; } } because I'm getting this error : request for member 'value' in something not a structure or union Thank you for your help

  • How do you unit test a class that's meant to talk to data?

    - by Arda Xi
    I have a few repository classes that are meant to talk to different kinds of data, deriving from an IRepository interface laid out like so: In implementations, the code talks to a data source, be this a directory of XML files or a database or even just a cache. Is it possible to reliably unit test any of these implementations? I don't see a mock implementation working, because then I'm only testing the mock code and not the actual code.

  • Facebook Open Graph under a constrained application

    - by Hellnar
    Hello For an embedded system with internet (which works under a set-top box) I want to develop a primitive Facebook interface where users can type their user-names and password, showing their latest notificationsa, messages and other casual stuff via the recent Facebook Graph API. This middleware program uses Java ME to run programs (such as this simple facebook app) and it can connect to internet however it doesn't have a real web browser. Under this circumstance, is it possible to achieve such Facebook application? If you think so, what approach would you suggest ? Thanks

  • BeanDefinition class removed in Spring 4?

    - by mushtaq
    I am trying out the new Spring 4 release, and I found out that the BeanDefinition interface has been removed, if so what is the replacement class we should use in a scenario where we define a scope for a bean ? Prior to Spring release of 4 you could do this. @Bean @Scope(BeanDefinition.SCOPE_PROTOTYPE) class MyBean{ ... } EDIT As of Spring 4, can't you specify the spring bean scope in the @Scope Annotation, the only option given is to add a string and then the ProxyMode ?

  • Hide a base class method from derived class, but still visible outside of assembly

    - by clintp
    This is a question about tidyness. The project is already working, I'm satisfied with the design but I have a couple of loose ends that I'd like to tie up. My project has a plugin architecture. The main body of the program dispatches work to the plugins that each reside in their own AppDomain. The plugins are described with an interface, which is used by the main program (to get the signature for invoking DispatchTaskToPlugin) and by the plugins themselves as an API contract: namespace AppServer.Plugin.Common { public interface IAppServerPlugin { void Register(); void DispatchTaskToPlugin(Task t); // Other methods omitted } } In the main body of the program Register() is called so that the plugin can register its callback methods with the base class, and then later DispatchTaskToPlugin() is called to get the plugin running. The plugins themselves are in two parts. There's a base class that implements the framework for the plugin (setup, housekeeping, teardown, etc..). This is where DispatchTaskToPlugin is actually defined: namespace AppServer.Plugin { abstract public class BasePlugin : MarshalByRefObject, AppServer.Plugin.Common.IAppServerPlugin { public void DispatchTaskToPlugin(Task t) { // ... // Eventual call to actual plugin code // } // Other methods omitted } } The actual plugins themselves only need to implement a Register() method (to give the base class the delegates to call eventually) and then their business logic. namespace AppServer.Plugin { public class Plugin : BasePlugin { override public void Register() { // Calls a method in the base class to register itself. } // Various callback methods, business logic, etc... } } Now in the base class (BasePlugin) I've implemented all kinds of convenience methods, collected data, etc.. for the plugins to use. Everything's kosher except for that lingering method DispatchTaskToPlugin(). It's not supposed to be callable from the Plugin class implementations -- they have no use for it. It's only needed by the dispatcher in the main body of the program. How can I prevent the derived classes (Plugin) from seeing the method in the base class (BasePlugin/DispatchTaskToPlugin) but still have it visible from outside of the assembly? I can split hairs and have DispatchTaskToPlugin() throw an exception if it's called from the derived classes, but that's closing the barn door a little late. I'd like to keep it out of Intellisense or possibly have the compiler take care of this for me. Suggestions?

  • How do you raise a .Net event from an IronRuby class?

    - by Brian Genisio
    I'm trying to figure out how to implement an event in a ruby class. Specifically, I am trying to make my class implement an interface (INotifyPropertyChanged) that includes an event (PropertyChanged). I can create my add_PropertyChanged and remove_PropertyChanged methods... but then what? This is what my class looks like so far: class TestClass include System::ComponentModel::INotifyPropertyChanged def add_PropertyChanged(handler) end def remove_PropertyChanged(handler) end end

  • What are the best practices for implementing the == operator for a class in C#?

    - by remio
    While implementing an == operator, I have the feeling that I am missing some essential points. Hence, I am searching some best practices around that. Here are some related questions I am thinking about: How to cleanly handle the reference comparison? Should it be implemented through a IEquatable<T>-like interface? Or overriding object.Equals? And what about the != operator? (this list might not be exhaustive).
