  • "Could not load file or assembly" error on trying to access auxillary assemblies from COM

    - by Codex
    We have the project structure as follows: COMExposedCCW.dll -refers- BusinessLayer.dll -refers- Utils.dll COMExposedCCW.dll -refers- Utils.dll The COMExposedCCW.dll has been registered for COM interop. From the COM application{Excel} we can successfully create the CCW object and access its properties, but when we try to invoke methods that refer to the Business/Utils layer, it throws an exception that the file or assembly{Business/Utils} could not be found. The Business/Utils dlls are present in the same folder as the CCW. On copying the Business/Utils to the COM application directory it works fine. I've tried the following: Set "HintPath/" in the CCW project I dont want to dynamically load the assemblies using Reflection {there should be a more elegant solution} Thanks in advance.

  • Copied Netbeans IDE Maven Web project failes to compile

    - by Quaternion
    If I am going to make serious changes to my project I like to make a copy (right click project and select copy). I have created copies of my projects many times (maven web applications included) without issue. Now all I do is copy the project making no changes, leaving the copy settings on default (project name etc) and then try to run it and spring decides to take issue with it. Again I try running the original and it works. I deleted the faulty copy, restarted and tried again and still it does not work. Here are my maven/system details: Apache Maven 2.2.1 (rdebian-4) Java version: 1.6.0_20 Java home: /usr/lib/jvm/java-6-openjdk/jre Default locale: en_CA, platform encoding: UTF-8 OS name: "linux"

  • Add Your Own Domain to Your WordPress.com Blog

    - by Matthew Guay
    Now that you’ve got a nice blog on WordPress.com, why not get your own domain to brand your site?  Here’s how you can easily register a new domain or move your existing domain to your WordPress site. By default, your free WordPress address is yourblog’sname.wordpress.com.  But whether this is a personal or a company blog, it can be nice to have your own domain to really brand your site and make it your own.  Or, if you already have another website and want to use WordPress as a blog for it, you could even add blog.yoursite.com or any other subdomain. Adding a domain to your WordPress.com is a paid upgrade; registering and mapping a new domain to your account costs $14.97 a year, while mapping a domain you already own to your WordPress blog costs $9.97 a year. Getting Started Login to your blog’s dashboard, click the arrow beside Upgrades in the sidebar, and select Domains. Enter the domain or subdomain you want to add to your site in the text box, and click Add domain to blog.   If you entered a new domain you want to register, WordPress will make sure the domain is available and then present you a registration form to register the domain.  Enter your information, and then click Register Domain.   Or, if you enter a domain that’s already registered, you will see the following prompt. If this domain is a domain you own, you can map it to WordPress.com.  Login to your domain registrar account and switch your nameserver to: NS1.WORDPRESS.COM NS2.WORDPRESS.COM NS3.WORDPRESS.COM Your DNS settings page for your domain may be different, depending on your registrar.  Here’s how our domain settings looked. Alternately, if you’re wanting to map a subdomain, such as blog.yoursite.com to your WordPress blog, create the following CNAME record on your domain register.  You may have to contact your domain registrar’s support to do this.  Substitute your subdomain, domain, and blog name when creating the record. subdomain.yourdomain.com. IN CNAME yourblog.wordpress.com. Once your settings are correct, click Try Again in your WordPress dashboard.  The DNS settings may take a while to update, but once WordPress can tell your DNS settings point to it, you will see the following confirmation screen.  Click Map Domain to add this domain to your WordPress blog. Now you’re ready to pay for your domain mapping or registration.  Depending on your purchase, the information and price shown may be different.  Here we’re mapping a domain we already have registered, so it costs $9.97.  Select your method of payment, enter your payment information or signin with your Paypal account, and continue as usual. Once your purchase is finished, you’ll be returned to the Domains page on WordPress.  Try going to your new domain, and make sure it opens your blog.  If it works, then click the bullet beside the new domain, and click Update Primary Domain.  Now, when people visit your WordPress site, they’ll see your new domain in the address bar.  You can still access your blog from your old yourname.wordpress.com address, but it will redirect to you new domain. Conclusion Having a personalized domain is a great way to make your blog more professional, while still taking advantage of the ease of use that WordPress.com offers.  And, if you have your own domain, you can easily move to your site traffic to a different hosting provider in the future if you need to.  The process is slightly complicated, but for $15/year we found this one of the best upgrades you could do to your WordPress.com blog. If you want to see an example of a site created with Wordpress, check out Matthew’s tech site techinch.com.

  • Does google contribute ranking from cdn.example.com to example.com?

    - by DesignerGuy
    Background From my understanding, http://mywebsite.com/image.jpg, can help the ranking of http://mywebsite.com in a search engine, such as Google (obviously the search engine of primary concern). So, SEO-wise, moving an image to http://whatever-cdn.com/my-account/image.jpg is bad. A popular solution is to use a CNAME record, such as http://cdn.mywebsite.com, so that image.jpg can be accessed at http://cdn.mywebsite.com/image.jpg. The question Does http://cdn.mywebsite.com/image.jpg rank as effectively as http://mywebsite.com/image.jpg ? Does it help boost the main http://mywebsite.com ? Or, does it rank independently because it is a subdomain? Is there another option (a way to use a CDN without sacrificing ranking)?

  • Error Connecting to Third Party App via COM: mscorlib Exception from HRESULT: 0x80040202

    - by Dave
    One particular user is getting an exception when connecting an application I created to a third party app using COM. The connection fails with the following error: Source: mscorlib Message: Exception from HRESULT: 0x80040202 This software works fine for other users. Any ideas what could be going on? The error occurs just before the app adds some event handlers to some of the COM objects from the third party app. It is able to successfully instantiate the objects, though.

  • COM Interop between 32 bit and 64 bit applications

    - by rip
    I have a .NET windows forms application compiled as x84 – it needs to be compiled as x84 because it references 3rd party DLLs which are 32 bit. The application uses COM interop to automate Office applications and also AutoCAD. My question is: will my COM interop code work okay on a 64 bit operating system against the 64 bit versions of Office and AutoCAD? I’m going to try this out but I wondered whether someone knew of any problems?

  • COM Local Server

    - by Gamer
    Hi, Similar to LocalServer32, which is used to specify the path to a 32Bit Local COM server, is there any registry entry for specifying the path to a 64Bit Local COM Server? If there is none, can we use LocalServer32 for 64Bit servers also? Note: In my knowledge there are only 2 registry entries - LocalServer and LocalServer32. According to MSDN the former is used for registering 16bit server and the latter to register a 32bit server. Thanks and Regards, Gamer

  • Listing available COM Objects with Powershell

    - by outtacontrol
    I am currently using the following script to list the available COM Objects on my machine. $path = "REGISTRY::HKEY_CLASSES_ROOT\CLSID\*\PROGID" foreach ($obj in dir $path) { write-host $obj.GetValue("") } I read on another website that the existence of the InProcServer32 key is evidence that the object is 64 bit compatible. So using powershell how can I determine the existence of InProcServer32 for each COM Object? If that is even the correct way of establishing whether it is 32 bit or 64 bit.

  • Member variable pointers to COM objects

    - by drelihan
    Hi Folks, Is there any problem with keeping member variable pointer refernces to COM objects and reussing the reference through out the class in C++. Is anybody aware of a reason why you would want to call .CreateInstance every time you wanted a to use the COM object i.e. you were getting a fresh instance each time. I cannot see any reason who you would want to do this, Thanks, (No is an acceptable answer!!!)

  • WCF service and COM interop callback

    - by Sjblack
    I have a COM object that creates an instance of a WCF service and passes a handle to itself as a callback. The com object is marked/initialized as MTA. The problem being every instance of the WCF service that makes a call to the callback occurs on the same thread so they are being processed one at a time which is causing session timeouts under a heavy load. The WCF service is session based not sure if that makes any difference.

  • COM Dual Interfaces

    - by Tony
    A dual interface in COM is one that is able to be accessed via a DispInterface or via VTable methods. Now can someone tell me what is exactly what the difference is between the two methods? I thought that a VTable is a virtual table which holds the pointers to the different functions when implementing a class hierarchy which has virtual functions that can be overridden in child classes. However I do not see how this is related to a dual interface in COM?

  • Finalizing a COM object

    - by Neverrav
    I'm trying to implement a singleton class, that holds a com object inside it. Class implements IDisposable interface, but when I try to implement a finalization method, I get an exception of access to com object from another thread. This happens because clr uses a different thread when finalizes objects. Is there any way to implement such a thing or maybe I just doing something wrong?

  • Translate COM error codes in C#

    - by Paul Keister
    In C, Pascal, and C++ it is possible to use the FormatMessage function to retrieve a "friendly" error message that corresponds to a COM HRESULT error code. This question contains sample code that demonstrates the C++ approach. Of course it would be possible to build a managed C++ assembly to perform this function for C# and VB.NET code, but I'm wondering: is there a way to translate COM error codes using the .NET system libraries?

  • Remote DLL Registration without access to HKEY_CLASSES_ROOT

    - by mohlsen
    We have a legacy VB6 application that updates itself on startup by pulling down the latest files and registering the COM components. This works for both local (regsvr32) ActiveX COM Components and remote (clireg32) ActiveX COM components registered in COM+ on another machine. New requirements are preventing us from writing to HKEY_LOACL_MACHINE (HKLM) for security reasons, which is what obviously happens by default when calling regsvr32 and clireg32. We have come up with an way to register the local COM componet under HKEY_CURRENT_USER\Software\Classes (HKCU) using the RegOverridePredefKey Windows API method. This works by redirecting the inserts into the registry to the HKCU location. Then when the COM components are instantiated, windows first looks to HKCU before looking for component information in HKLM. This replaces what regsvr32 is doing. The problem we are experiencing at this time is when we attempt to register VBR / TLB using clireg32, this registration process also adds registration keys to HKEY_LOACL_MACHINE. Is there a way to redirect clireg32.exe to register component is HKEY_CURRENT_USER? Are there any other methods that would allow us to register these COM+ components on clients machine with limited security access? Our only solution at this time would be to manually write the registration information to the registry, but that is not ideal and would be a maint issue.

  • Securely persist session between https://secure.yourname.com and http://www.yourname.com on rails ap

    - by Matt
    My rails site posts to a secure host (e.g. 'https://secure.yourname.com') when the user logs into the site. Session data is stored in the database, with the cookie containing only the session ID. The problem is that when the user returns to a non-https page, such as the home page (e.g. 'http://www.yourname.com') the user appears to have logged out. I believe the reason for this is that a separate cookie is stored for each host (www vs. secure). Is this correct? What is the best secure way to persist the session between both the http and https sections of the site? Does anyone know of any plugins that address this problem? The site runs on Heroku.

  • ActiveX component can't create Object Error? Check 64 bit Status

    - by Rick Strahl
    If you're running on IIS 7 and a 64 bit operating system you might run into the following error using ASP classic or ASP.NET with COM interop. In classic ASP applications the error will show up as: ActiveX component can't create object   (Error 429) (actually without error handling the error just shows up as 500 error page) In my case the code that's been giving me problems has been a FoxPro COM object I'd been using to serve banner ads to some of my pages. The code basically looks up banners from a database table and displays them at random. The ASP classic code that uses it looks like this: <% Set banner = Server.CreateObject("wwBanner.aspBanner") banner.BannerFile = "wwsitebanners" Response.Write(banner.GetBanner(-1)) %> Originally this code had no specific error checking as above so the ASP pages just failed with 500 error pages from the Web server. To find out what the problem is this code is more useful at least for debugging: <% ON ERROR RESUME NEXT Set banner = Server.CreateObject("wwBanner.aspBanner") Response.Write(err.Number & " - " & err.Description) banner.BannerFile = "wwsitebanners" Response.Write(banner.GetBanner(-1)) %> which results in: 429 - ActiveX component can't create object which at least gives you a slight clue. In ASP.NET invoking the same COM object with code like this: <% dynamic banner = wwUtils.CreateComInstance("wwBanner.aspBanner") as dynamic; banner.cBANNERFILE = "wwsitebanners"; Response.Write(banner.getBanner(-1)); %> results in: Retrieving the COM class factory for component with CLSID {B5DCBB81-D5F5-11D2-B85E-00600889F23B} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)). The class is in fact registered though and the COM server loads fine from a command prompt or other COM client. This error can be caused by a COM server that doesn't load. It looks like a COM registration error. There are a number of traditional reasons why this error can crop up of course. The server isn't registered (run regserver32 to register a DLL server or /regserver on an EXE server) Access permissions aren't set on the COM server (Web account has to be able to read the DLL ie. Network service) The COM server fails to load during initialization ie. failing during startup One thing I always do to check for COM errors fire up the server in a COM client outside of IIS and ensure that it works there first - it's almost always easier to debug a server outside of the Web environment. In my case I tried the server in Visual FoxPro on the server with: loBanners = CREATEOBJECT("wwBanner.aspBanner") loBanners.cBannerFile = "wwsitebanners" ? loBanners.GetBanner(-1) and it worked just fine. If you don't have a full dev environment on the server you can also use VBScript do the same thing and run the .vbs file from the command prompt: Set banner = Server.CreateObject("wwBanner.aspBanner") banner.BannerFile = "wwsitebanners" MsgBox(banner.getBanner(-1)) Since this both works it tells me the server is registered and working properly. This leaves startup failures or permissions as the problem. I double checked permissions for the Application Pool and the permissions of the folder where the DLL lives and both are properly set to allow access by the Application Pool impersonated user. Just to be sure I assigned an Admin user to the Application Pool but still no go. So now what? 64 bit Servers Ahoy A couple of weeks back I had set up a few of my Application pools to 64 bit mode. My server is Server 2008 64 bit and by default Application Pools run 64 bit. Originally when I installed the server I set up most of my Application Pools to 32 bit mainly for backwards compatibility. But as more of my code migrates to 64 bit OS's I figured it'd be a good idea to see how well code runs under 64 bit code. The transition has been mostly painless. Until today when I noticed the problem with the code above when scrolling to my IIS logs and noticing a lot of 500 errors on many of my ASP classic pages. The code in question in most of these pages deals with this single simple COM object. It took a while to figure out that the problem is caused by the Application Pool running in 64 bit mode. The issue is that 32 bit COM objects (ie. my old Visual FoxPro COM component) cannot be loaded in a 64 bit Application Pool. The ASP pages using this COM component broke on the day I switched my main Application Pool into 64 bit mode but I didn't find the problem until I searched my logs for errors by pure chance. To fix this is easy enough once you know what the problem is by switching the Application Pool to Enable 32-bit Applications: Once this is done the COM objects started working correctly again. 64 bit ASP and ASP.NET with DCOM Servers This is kind of off topic, but incidentally it's possible to load 32 bit DCOM (out of process) servers from ASP.NET and ASP classic even if those applications run in 64 bit application pools. In fact, in West Wind Web Connection I use this capability to run a 64 bit ASP.NET handler that talks to a 32 bit FoxPro COM server which allows West Wind Web Connection to run in native 64 bit mode without custom configuration (which is actually quite useful). It's probably not a common usage scenario but it's good to know that you can actually access 32 bit COM objects this way from ASP.NET. For West Wind Web Connection this works out well as the DCOM interface only makes one non-chatty call to the backend server that handles all the rest of the request processing. Application Pool Isolation is your Friend For me the recent incident of failure in the classic ASP pages has just been another reminder to be very careful with moving applications to 64 bit operation. There are many little traps when switching to 64 bit that are very difficult to track and test for. I described one issue I had a couple of months ago where one of the default ASP.NET filters was loading the wrong version (32bit instead of 64bit) which was extremely difficult to track down and was caused by a very sneaky configuration switch error (basically 3 different entries for the same ISAPI filter all with different bitness settings). It took me almost a full day to track this down). Recently I've been taken to isolate individual applications into separate Application Pools rather than my past practice of combining many apps into shared AppPools. This is a good practice assuming you have enough memory to make this work. Application Pool isolate provides more modularity and allows me to selectively move applications to 64 bit. The error above came about precisely because I moved one of my most populous app pools to 64 bit and forgot about the minimal COM object use in some of my old pages. It's easy to forget. To 64bit or Not Is it worth it to move to 64 bit? Currently I'd say -not really. In my - admittedly limited - testing I don't see any significant performance increases. In fact 64 bit apps just seem to consume considerably more memory (30-50% more in my pools on average) and performance is minimally improved (less than 5% at the very best) in the load testing I've performed on a couple of sites in both modes. The only real incentive for 64 bit would be applications that require huge data spaces that exceed the 32 bit 4 gigabyte memory limit. However I have a hard time imagining an application that needs 4 gigs of memory in a single Application Pool :-). Curious to hear other opinions on benefits of 64 bit operation. © Rick Strahl, West Wind Technologies, 2005-2011Posted in COM   ASP.NET  FoxPro

  • Parse.com REST API in Java (NOT Android)

    - by Orange Peel
    I am trying to use the Parse.com REST API in Java. I have gone through the 4 solutions given here https://parse.com/docs/api_libraries and have selected Parse4J. After importing the source into Netbeans, along with importing the following libraries: org.slf4j:slf4j-api:jar:1.6.1 org.apache.httpcomponents:httpclient:jar:4.3.2 org.apache.httpcomponents:httpcore:jar:4.3.1 org.json:json:jar:20131018 commons-codec:commons-codec:jar:1.9 junit:junit:jar:4.11 ch.qos.logback:logback-classic:jar:0.9.28 ch.qos.logback:logback-core:jar:0.9.28 I ran the example code from https://github.com/thiagolocatelli/parse4j Parse.initialize(APP_ID, APP_REST_API_ID); // I replaced these with mine ParseObject gameScore = new ParseObject("GameScore"); gameScore.put("score", 1337); gameScore.put("playerName", "Sean Plott"); gameScore.put("cheatMode", false); gameScore.save(); And I got that it was missing org.apache.commons.logging, so I downloaded that and imported it. Then I ran the code again and got Exception in thread "main" java.lang.NoSuchMethodError: org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;Ljava/lang/Throwable;)V at org.apache.commons.logging.impl.SLF4JLocationAwareLog.debug(SLF4JLocationAwareLog.java:120) at org.apache.http.client.protocol.RequestAddCookies.process(RequestAddCookies.java:122) at org.apache.http.protocol.ImmutableHttpProcessor.process(ImmutableHttpProcessor.java:131) at org.apache.http.impl.execchain.ProtocolExec.execute(ProtocolExec.java:193) at org.apache.http.impl.execchain.RetryExec.execute(RetryExec.java:85) at org.apache.http.impl.execchain.RedirectExec.execute(RedirectExec.java:108) at org.apache.http.impl.client.InternalHttpClient.doExecute(InternalHttpClient.java:186) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:82) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:106) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:57) at org.parse4j.command.ParseCommand.perform(ParseCommand.java:44) at org.parse4j.ParseObject.save(ParseObject.java:450) I could probably fix this with another import, but I suppose then something else would pop up. I tried the other libraries with similar results, missing a bunch of libraries. Has anyone actually used REST API successfully in Java? If so, I would be grateful if you shared which library/s you used and anything else required to get it going successfully. I am using Netbeans. Thanks.

  • Encrypting using RSA via COM Interop = "The requested operation requires delegation to be enabled on

    - by Mr AH
    Hi Guys, So i've got this little static method in a .Net class which takes a string, uses some stored public key and returns the encrypted version of that key. This is basically so some user entered data can be saved an encrypted, then retrieved and decrypted at a later date. Pretty basic stuff and the unit test works fine. However, part of the application is in classic ASP. This then uses some COM visible version of the class to go off and invoke the method on the real class and return the same string to the COM client (classic ASP). I use this kind of stuff all the time, but in this case we have a major problem. As the method is doing something with RSA keys and has to access certain machine information to do so, we get the error: "The requested operation requires delegation to be enabled on the machine. I've searched around a lot, but can't really understand what this means. I assume I am getting this error on the COM but not the UT because the UT runs as me (Administrator) and classic ASP as IWAM. Anyone know what I need to do to enable IWAM to do this? Or indeed if this is the real problem here?

  • Making .NET assembly COM-visible and working for VB5

    - by Cyberherbalist
    I have an assembly which I have managed to make visible to VB6 and it works, but having a problem accomplishing the same thing with VB5. For VB6, I have built the assembly, made it COM-visible, registered it as a COM object etc., and the assembly shows in VB6's References list, and allows me to use it successfully. The Object Browser also shows the method in the assy. I copied the assembly and its TLB to a virtual workstation used for VB5 development, and ran Regasm, apparently successfully: C:\>C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727 \regasm arserviceinterface.dll /tlb:arserviceinterface.tlb Microsoft (R) .NET Framework Assembly Registration Utility 2.0.50727.3053 Copyright (C) Microsoft Corporation 1998-2004. All rights reserved. Assembly exported to 'C:\Projects\AR\3rd Party\ARService\arserviceinterface.tlb' , and the type library was registered successfully Note that the virtual W/S is Win2k and does not have .NET Fx 3.5 on it, just 2.0. The assembly shows up in the References that can be selected in VB5, but the method of the assembly doesn't show up in the Object Browser, and it is generally unusable. Either there is a step to do that I haven't done, or VB5 doesn't know how to use such a COM object. Note that the VB5 setup is on a virtual workstation, not the same workstation that VB6 is installed on. Any ideas? One thing that occurred to me is that I might need to generate and use a strong name on the workstation in question, but...
