  • Convert IDispatch* to a string?

    - by Rob
    I am converting an old VB COM object (which I didn't write) to C++ using ATL. One of the methods, according to the IDL, takes an IDispatch* as a parameter and the documentation and samples for this method claim that you can pass either a string (which is the progid of an object that will be created and used by the control) or an IDispatch* to an object that has already been created. How on earth do I implement this in ATL? For example, the IDL: [id(1)] HRESULT Test(IDispatch* obj); The samples (which are all JScript): obj.Test("foo.bar"); or var someObject = new ActiveXObject("foo.bar"); obj.Test(someObject); To make matters even more bizarre the actual VB code that implements this method actually declares the 'obj' parameter as a string! However, it all seems to work. Can you even pass a string to a COM method that takes an IDispatch*? If so, can I determine that the IDispatch* is actually a string in my C++ ATL code? Even better, if it's an IDispatch that implements a specific interface I will want to call methods on it, or instantiate an object if it's a string. Any ideas welcome!

  • Do the new NoPIA and Type Equivalence features in C#/.NET 4.0 mean Microsoft.mshtml.dll is no longer

    - by jpierson
    I'm maintaining a WPF based application which contains a WinForms based WebBrowser control that based on the IE web browser control. When we deploy, we have had to also supply Microsoft.mshtml.dll and do some custom configuration stuff for our ClickOnce publishing process as well in order to get things to work. I'm curious that with the new NoPIA and Type Equivalence features and dynamic type capabilities in C# 4.0 can we expect that if we upgrade that we can remove the dependencies on the Microsoft.mshtml.dll assembly? If so this will not only reduce the size of our deployment quite a bit but will also simplify our publishing process as well. It is my understanding that we should be able embed the types that normally get automatically generated into extra assemblies for COM types such as the MapPoint Control by Visual Studio. I don't know if this also applies to the Microsoft.mshtml.dll or even how it is done even in the most simple of cases. If somebody could provide an explanation about what the practical impact of these new features are on a project that relies on COM interop and especially the Microsoft.mshtml.dll assembly it would be of great help to me.

  • C# Late Binding for Parameterized Property

    - by optim
    I'm trying to use late binding to connect to a COM automation API provided by a program called Amibroker, using a C# WinForms project. So far I've been able to connect to everything in the API except one item, which I believe to be a "parameterized property" based on extensive Googling. Here's what the API specification looks like according to the docs (Full version here: http://www.amibroker.com/guide/objects.html): Property Filter(ByVal nType As Integer, ByVal pszCategory As String) As Long [r/w] A javascript snippet to update the value looks like this: AB = new ActiveXObject("Broker.Application"); AA = AB.Analysis; AA.Filter( 0, "market" ) = 0; Using the following C# late-binding code, I can get the value of the property, but I can't for the life of me figure out how to set the value: object[] parameter = new object[2]; parameter[0] = Number; parameter[1] = Type; object filters = _analysis.GetType().InvokeMember("Filter", BindingFlags.GetProperty, null, _analysis, parameter); So far I have tried: using BindingFlags.SetProperty, BindingFlags.SetField casting the returned object to a PropertyInfo object and trying to update the value using it adding extra object containing the value to the parameters object various other things as last-ditch efforts From what I can see, this should be straight-forward, but I'm finding the late binding in C# to be cumbersome at best. The property looks like a method call to me, which is what is throwing me off. How does one assign a value to a method, and what would the prototype for late-binding C# code look like for it? Hopefully that explains it well enough, but feel free to ask if I've left anything unclear. Thanks in advance for any help! Daniel

  • Visual Studio project remains "stuck" when stopped

    - by Traveling Tech Guy
    Hi, Currently developing a connector DLL to HP's Quality Center. I'm using their (insert expelative) COM API to connect to the server. An Interop wrapper gets created automatically by VStudio. My solution has 2 projects: the DLL and a tester application - essentially a form with buttons that call functions in the DLL. Everything works well - I can create defects, update them and delete them. When I close the main form, the application stops nicely. But when I call a function that returns a list of all available projects (to fill a combo box), if I close the main form, VStudio still shows the solution as running and I have to stop it. I've managed to pinpoint a single function in my code that when I call, the solution remains "hung" and if I don't, it closes well. It's a call to a property in the TDC object get_VisibleProjects that returns a List (not the .Net one, but a type in the COM library) - I just iterate over it and return a proper list (that I later use to fill the combo box): public List<string> GetAvailableProjects() { List<string> projects = new List<string>(); foreach (string project in this.tdc.get_VisibleProjects(qcDomain)) { projects.Add(project); } return projects; } My assumption is that something gets retained in memory. If I run the EXE outside of VStudio it closes - but who knows what gets left behind in memory? My question is - how do I get rid of whatever calling this property returns? Shouldn't the GC handle this? Do I need to delve into pointers? Things I've tried: getting the list into a variable and setting it to null at the end of the function Adding a destructor to the class and nulling the tdc object Stepping through the tester function application all the way out, whne the form closes and the Main function ends - it closes, but VStudio still shows I'm running. Thanks for your assistance!

  • Why won't my Setup Project Perform my Custom Registration Process

    - by Jordan S
    I am trying to write an Setup Project/Installer for a class library driver that I wrote in C# using Visual Studio 2008. The driver project has a section of code that looks like this... [ComRegisterFunction] public static void RegisterASCOM(Type t) { Trace.WriteLine("Registration Started."); DoRegistration(true); } In the driver project Properties - "Assembly Information" I have set checked the box that says Make COM-Visible = true. I added a Setup Project to the solution in VS, added the output dll from the driver project so that it installs on the target machine and set the Register property of the dll to "vsdraCOM". So, my understanding is that when the installer runs it SHOULD execute the methods of the dll that are marked with [COMRegisterFunction]. Using SysInternals Debug View I can monitor when the above code snippet is hit by watching for the "Registration started" text to show up in the window. When I build the solution, I can see the text show up so I know the driver is registering properly. The problem is that when I run the installer, I don't think it is doing the registration bit. I see nothing show up in Debug View. And if i try to access my driver via another application I get an error saying it "Cannot create ActiveX object". Why does the registration not occur during the install process? The driver does register for COM but it does NOT call my custom registration method. Does anyone have and suggestions of what I could be missing? Is there another way I can debug this? (I can provide more code if anyone want's to take a look!!)

  • Binary to Ascii and back again

    - by rross
    I'm trying to interface with a hardware device via the serial port. When I use software like Portmon to see the messages they look like this: 42 21 21 21 21 41 45 21 26 21 29 21 26 59 5F 41 30 21 2B 21 27 42 21 21 21 21 41 47 21 27 21 28 21 27 59 5D 41 32 21 2A 21 28 When I run them thru a hex to ascii converter the commands don't make sense. Are these messages in fact something different than hex? My hope was to see the messages the device is passing and emulate them using c#. What can I do to find out exactly what the messages are?

  • NATUPnP IStaticPortMappingCollection::Add returns HRESULT 0x80040214

    - by dauphic
    I'm attempting to use Microsoft's NATUPnP library to create a port mapping. Unfortunately, I'm unable to. My router supports UPnP, it is enabled, and I can create mappings with other (pre-built) applications. I can also read existing mappings. When I call the Add function, it fails and returns HRESULT 0x80040214 (which is undocumented). I have absolutely no idea what might be going on. IStaticPortMapping* newMapping = NULL; hr = portMappings->Add(27015, L"TCP", 27015, L"MYCOMPUTER", VARIANT_TRUE, L"TestMapping", &newMapping); You can see the reference for this function at http://msdn.microsoft.com/en-us/library/aa366148%28v=VS.85%29.aspx. The portMappings object is, of course, valid; I use it earlier in the code to enumerate over the existing mappings. If anyone has experience with this and might know what my problem is, I'd appreciate any help.

  • Why not port Linux kernel to Common Lisp?

    - by rplevy
    Conventional wisdom states that OS kernels must be written in C in order to achieve the necessary levels of performance. This has been the justification for not using more expressive high level languages. However, for a few years now implementations of Common Lisp such as SBCL have proven to be just as performant as C. What then are the arguments against redoing the kernel in a powerfully expressive language, namely Common Lisp? I don't think anyone (at least anyone who knows what they are talking about) could argue against the fact that the benefits in transparency and readability would be tremendous, not to mention all the things that can't be done in C that can be done in Lisp, but there may be implementation details that would make this a bad idea.

  • Remote EJB lookup issue with WebSphere 6.1

    - by marc dauncey
    I've seen this question asked before, but I've tried various solutions proposed, to no avail. Essentially, I have two EJB enterprise applications, that need to communicate with one another. The first is a web application, the second is a search server - they are located on different development servers, not in the same node, cell, or JVM, although they are on the same physical box. I'm doing the JNDI lookup via IIOP, and the URL I am using is as follows: iiop://searchserver:2819 In my hosts file, I've set searchserver to 127.0.0.1. The ports for my search server are bound to this hostname too. However, when the web app (that uses Spring btw) attempts to lookup the search EJB, it fails with the following error. This is driving me nuts, surely this kind of comms between the servers should be fairly simple to get working. I've checked the ports and they are correct. I note that the exception says the initial context is H00723Node03Cell/nodes/H00723Node03/servers/server1, name: ejb/com/hmv/dataaccess/ejb/hmvsearch/HMVSearchHome. This is the web apps server NOT the search server. Is this correct? How can I get Spring to use the right context?

  • Visual Studio 2008 Web Project error: Unable to start program http://localhost:port

    - by JookyDFW
    I am re-hashing this question because I have looked at over 50 threads in different forums and have not been able to get a resolution to my problem. Here are the specs: Windows XP SP3, Visual Studio 2008 SP1, .NET 3.5, ASP. NET MVC 2 project, IE 7 (was IE 8) Up until a few days ago I was not having any issues. It is now happening on any solution that I try to debug. I start a debug session (F5), the solution rebuilds, a VS development web server starts and then I get this error: Unable to start program http://localhost:2012/ If I open a web browser and enter the URL the application loads up. I had upgraded to IE 8 a few weeks ago and read there may be some issues so it has been uninstalled and I am currently on IE 7. Also, while IE 8 was installed I had switched my default browser to Firefox but my current default broweser is now IE7. I have reveiewed the threads on this site and others and have not been able to fix the issue. Any help would be appreciated.

  • Ruby SerialPorts Gem

    - by Seth Archer
    Using Ruby SerialPorts Gem to interact with hardware. When I write a byte array to the hardware using a program called "Serial Port Monitor" the hardware responds correctly. However, when I write the same byte array using ruby it doesn't work unless I do a read request just before the write request. This device doesn't respond correctly with this sp = SerialPort.new(args) sp.write [200.chr, 30.chr, 6.chr, 5.chr, 1.chr, 2.chr, 0.chr, 244.chr] But it does if I add a read request before the write. Like this sp SerialPort.new(args) sp.read sp.write [200.chr, 30.chr, 6.chr, 5.chr, 1.chr, 2.chr, 0.chr, 244.chr] This works, but I'm at a loss as to why. I should also add that the first snippet does work occasionally maybe 1/10 of the time.

  • CherryPy sessions for same domain, different port

    - by detly
    Consider the script below. It will launch two subprocesses, each one a CherryPy app (hit Ctrl+C or whatever the KeyboardInterrupt combo is on your system to end them both). If you run it with CP 3.0 (taking care to change the 3.0/3.1 specific lines in "StartServer"), then visit: http://localhost:15002/ ...you see an empty dict. Then visit: http://localhost:15002/set?val=10 http://localhost:15002/ ...and you see the newly populated dict. Then visit: http://localhost:15012/ ...and go back to http://localhost:15002/ ...and nothing has changed. If you try the same thing with CP 3.1 (remember the lines in "StartServer"!), when you get to the last step, the dict is now empty. This happens in Windows and Debian, Python 2.5 and 2.6. You can try all sorts of things: changing to file storage, separating the storage paths... the only difference it makes is that the sessions might get merged instead of erased. I've read another post about this as well, and there's a suggestion there to put the session tools config keys in the app config rather than the global config, but I don't think that's relevant to this usage where the apps run independently. What do I do to get independent CherryPy applications to NOT interfere with each other? Note: I originally asked this on the CherryPy mailing list but haven't had a response yet so I'm trying here. I hope that's okay. import os, os.path, socket, sys import subprocess import cgi import cherrypy HTTP_PORT = 15002 HTTP_HOST = "127.0.0.1" site1conf = { 'global' : { 'server.socket_host' : HTTP_HOST, 'server.socket_port' : HTTP_PORT, 'tools.sessions.on' : True, # 'tools.sessions.storage_type': 'file', # 'tools.sessions.storage_path': '1', # 'tools.sessions.storage_path': '.', 'tools.sessions.timeout' : 1440}} site2conf = { 'global' : { 'server.socket_host' : HTTP_HOST, 'server.socket_port' : HTTP_PORT + 10, 'tools.sessions.on' : True, # 'tools.sessions.storage_type': 'file', # 'tools.sessions.storage_path': '2', # 'tools.sessions.storage_path': '.', 'tools.sessions.timeout' : 1440}} class Home(object) : def __init__(self, key): self.key = key @cherrypy.expose def index(self): return """\ <html> <body>Session: <br>%s </body> </html> """ % cgi.escape(str(dict(cherrypy.session))) @cherrypy.expose def set(self, val): cherrypy.session[self.key.upper()] = val return """\ <html> <body>Set %s to %s</body> </html>""" % (cgi.escape(self.key), cgi.escape(val)) def StartServer(conf, key): cherrypy.config.update(conf) print 'Starting server (%s)' % key cherrypy.tree.mount(Home(key), '/', {}) # Start the web server. #### 3.0 # cherrypy.server.quickstart() # cherrypy.engine.start() #### #### 3.1 cherrypy.engine.start() cherrypy.engine.block() #### def Main(): # Start first webserver proc1 = subprocess.Popen( [sys.executable, os.path.abspath(__file__), "1"]) proc2 = subprocess.Popen( [sys.executable, os.path.abspath(__file__), "2"]) proc1.wait() proc2.wait() if __name__ == "__main__": print sys.argv if len(sys.argv) == 1: # Master process Main() elif(int(sys.argv[1]) == 1): StartServer(site1conf, 'magic') elif(int(sys.argv[1]) == 2): StartServer(site2conf, 'science') else: sys.exit(1)

I already found this link in the web http://www.apache.org/~avik/dist/poi-2.5.1-dev-20040708.dll But the version of apache poi now is 3.6, I was wondering if there is a latest version out there? Does the apache foundation support such porting? I already tried to search the apache website too with no avail. As for using Microsoft library, the excel interopt is not that good for concurrent processing like a web backend. If I use the DocumentFormat.OpenXML library, I have a limitation of creating office 2007 document only.

  • I want to port my delicious bookmarks to my website

    - by puneet
    I started building a app that will automatically download my delicious bookmarks, and save to a database, so they I can view them on my own website in my favoured format. I am forced to use oAuth, as I have a yahoo id to login to delicious. The problem is I am stuck at the point where oAuth requires a user to manually go and authenticate. Is there a code/ guidelines available anywhere I can follow? All I want is a way to automatically save my bookmarks to my database. Any help is appreciated. I can work on java, .net and php. Thanks.

  • Using com.sun.net.httpserver.HttpServer for comet/cometd

    - by Paul
    Hi Wayne :) I want to use HttpServer, which you mentioned, and I think is cool to do comet/cometd. I am wondering how tough it is to do it so that I can take the waiting connections off the thread and into some waiting queue. Also, am I correct in that it looks like it is using nio? Also, is there any better examples? I always get caught up in the terminology that the javadoc uses... Thanks :)

  • Port a live system from App Engine Helper to App Engine Patch

    - by Alexander
    I am running a live system that is currently serving about 20K pages a day which is based on App Engine Helper (Python) with session support provided by AppEngine utilities. One problem that I have been having is that sessions are occasionally randomly logging out. I would like to try using the App Engine Patch, since it has "native" django session support, but I am worried that this is possibly going to be like doing a brain transplant. Specifically, current database models are all inhereted from BaseModel provided by the App Engine Helper. While, App Engine Patch does not have this inheritance. Does anyone know if it is possible to migrate a live system from App Engine Helper to App Engine Patch? If so, do you have any advice or warnings that I should heed, before attempting this transition? Thank you and kind regards Alex
