I have an application C# for fingerprint reader u are u 4500 , so now I need to develop it in Powerbuilder. My question is if someone has any example of this app in powerbuilder.
Kind regards .
Without knowing anything about your fingerprint application I would recommend a COM visible dll (using C#) with exposed methods PowerBuilder can call to provide the functionality you require. There are many examples of using COM with PowerBuilder online. It is very unlikely someone will have 'any example of this app in powerbuilder' they are willing to share.

I found this post Memory leak with Chromium Embedded interop ActiveX control using CEFSharp WPF
where it seems that a member has successfully created an interop activex control. This is what I need to do and I need some help doing so.
If you want to USE the interop ActiveX control like mentioned in the post you included than simply use it the same way the other person did. Find out where they got the interop control and use it like normal in PB.
I think that you are wanting to develop an ActiveX wrapper which will then be used in PB. As the name implies (wrapper) just create an ActiveX project in Visual Studio and start mapping the properties/events/functions until your wrapper is complete. If you didn't know the basic steps for creating a wrapper than it shouldn't take more than ten minutes on the internet to get an idea of what that is and how to do it.
Also to help you out being a new StackOverflow member, I'd suggest using better tags for the best results. I see why you chose a few of them but 3 of 4 have fewer than 100 followers so your question is not being seen much at all (thank goodness for you on this one). I'd have put this under .NET, C# for top exposure and maybe keep the chromium tag which will help people searching for the answer down the road, it isn't helping you find the answer with less than 100 followers.
Oh, if you need someone to write the wrapper- I am looking for work and can do it for few hours/days pay depending on how much you need exposed.
Working on an appliance and would like to support zero configuration feature. That way users can look for the device on the network and simply double click an icon to access the web interface without having to configure it or know its ip address.
Tried to use UPNPLib_TLB but functions seem to be read-only; am I right? I can create a device using CoUPnPDevice.Create but can't set a FriendlyName or a URL.
Tried to use Deltics Bonjour service but it crashes on create (ACCESS_VIOLATION). The demo code uses a custom test unit which complicates experimentation.
After much research it does not look like there is a component available for this and would appreciate some pointers. Has anyone successfully created a zeroconf broadcast either via UPnP or Bonjour with Delphi XE2/5.. I can go back to Delphi 7 if required. Target = Windows 7.
NOTE: To be clear, I can find existing devices on the network and don't want to enumerate existing devices but what I want is to broadcast my service so that my box behaves like a network printer for example. The only service I need to expose is the URL so that users can access an embedded web server.
Appreciate the help!
EDIT
With the tips provided I did some research and getting this done the RAD way is not possible.
Using MS APIs directly is time consuming and requires a level of understanding of C that I don't have. Porting the Delphi 5/Indy 7 component to XE2/5 will require a good amount of work and debugging.
I discovered UPnP developer tools from Intel now open source here: Developer Tools for UPnP. This tools makes it really simply to create a server in 10-15 lines of code. Intel provides a DLL that I can call from VS Express as follows and it works great:
device = UPnPDevice.CreateRootDevice();
device.FriendlyName = 'My name';
device.PresentationURL = 'URLToEmbeddedServer";
..
I tried to use headconv7 tool to convert the .h file Intel's UPNP.DLL to a pascal file and call the external functions within the DLL directly from Delphi but there were too many problems with the conversion.
It's too bad because the Intel library makes it really simple to create UPnP stacks and the approach would apply itself very well to a component but for now its quicker to use .NET and VS Express to get the job done.
When using UPNPLib_TLB, you are not supposed to create a UPnPDevice object directly. UPnpDevice describes a known device on the network, which is why its properties are read-only.
Read the documentation:
Control Point API
Finding Devices
You are supposed to create an instance of the UPnPDeviceFinder class instead. Its search methods will give you a UPnDevice object for each device that is found.
I'm new to iOS, have been developing in Delphi for many years.
I don't know FPC well and i find it very hard to figure out which classes are available on iOS.
is there any FireMonkey classes for calling web services and parsing xml?
Yes you can call a webservice :)
No it is not simple :(
You need to access the iOS framework directly...
The following code fragments will help...
First a pascal example of how to send/receive data via TCP

Secondly, you will need to wrap the call using the relevant headers. See...

It is a fair bit of work, but it can be done. Good luck!
You can also try to use RealThinClient (RTC) SDK to allow your Delphi XE2 FireMonkey iOS client to connect to a RTC SDK server. Not SOAP, but I've managed to send data back and forth between the two layers (just in case you do not have to use SOAP, but are merely looking for some way to connect an iOS client to a server)...
I am busy with a project where I have to code a program in Delphi that will translate an English word to another language. What would be the easiest way to approach this? I was thinking about using Microsoft Translator V2 API from Delphi, but it seems very complicated and I am not yet that experienced in Delphi. Any other suggestions?
Thanks in advance :)
Thanks to RRUZ you can follow this article about Microsoft Translator V2 API implementation for Delphi; inluding the full (even speaking) example.
If you don't have to be self-contained, you could make a webservice call (soap, etc..) to the cloud (google, etc..). The nature of your app (is it a translation program? or do you just want to provide translation in another app, along with spellcheck, thesaurus, syntax highlight, etc..?) will determine whether this is feasible or not.
Does anyone have experience integrating SmartCard authentication in their Win32 apps? If so, are there any preferred libraries?
Try SecureBlackbox, A component that works fine for me, a second choice can be
Delphi PC/SC SmartCard Component 0.91.
try
Well I guess that you have an SmartCard reader ... if so (and if you don't have one I don't know how you are going to manage this) then it must have some interface, RS232, USB, TCP/IP ... any one will do.
Communication protocol usually is available at SmartCard reader manufacturer. Few lines, and you will have it working in Delphi.
You need to read the developer manual that comes with reader you're going to use. It might only use PC-SC (by MS) to communicate, if so you can use the component specified by RRUZ, however it doesn't work with D2009. Otherwise you'll need to use API provided by SDK.
