  • Call to C++ COM interface from C# being blocked

    - by dauphic
    I have a C++ DLL that exposes a COM interface. A C# application uses the COM interface. I've recently run into a problem where some calls to the COM interface are taking 500-5000 ms to return, though they should return almost instantly (no longer than 10 ms). Profiling the application shows that all of the delay is being caused by the 'thread being blocked;' no other information is available. There are no locks, etc. in my code, so the blocking has to be occurring internally in the COM/interop code. Only one thread interfaces with the COM DLL. Any ideas what could be causing this, and how I would fix it? EDIT: Further investigation shows that the block is occuring when the C++ returns to the C#.

  • Alternative to COM blind aggregation in .NET for class with private interface

    - by Philip
    When extending a COM class in unmanaged C++ where the original class has private interfaces, one way to do this is through the concept of blind aggregation. The idea is that any interface not explicitly implemented on the outer aggregating class is 'blindly' forwarded to the inner aggregated class. Now .NET as far as I can figure out does not support COM aggregation natively. A somewhat tedious workaround is to create a .NET class where you implement all the required COM interfaces directly on the .NET class and simply forward to an instance of the actual COM class for any methods you don't want to override. The problem I have is when the original COM object has one or more private interfaces, i.e. undocumented interfaces that are nonetheless used by some consumers of the original class. Using blind aggregation in unmanaged C++ this is a non-issue as the calls to the private interfaces are automatically forwarded to the original class, however I can't find any way of doing the same thing in .NET. Are there any other ways of accomplishing this with .NET?

  • Delphi - COM/OLE starting example needed

    - by durumdara
    Hi! 10 years have ellapsed since I used COM/OLE, and I forget 90% of them. Now we need to make a COM object to access some data from PHP/Python (this is specific thing, the php ODBC don't access the output params of a DataBase - like stored proc output), and my idea the I realize a minimal object with one method, and PHP/Python can call this to get the output... procedure ExecSQL(Config, IP, Port, DBName, SQL, IDFieldName : variant) : output output is [IDValue, ErrorMsg, HResult] Please help me a very little example, how to start it? I need only this, but I'm confused by many ActiveX/COM in the palette. What I need to use to make a simple COM DLL, and how to register my COM object with this DLL? Thanks: dd

  • Use of COM object in IIS 7

    - by Wouter d.A.
    Hi all, I am currently moving an ASP.NET web-project from an IIS 6 to a IIS 7 hosting environment. Everything seems to be running OK, except my calls to a COM object. I can perfectly instantiate an object of the COM type, but when I call one of its methods, the IIS crashes. The event log reports an error code "0xc0000374", which indicates a heap corruption. When I run the application inside the visual studio development server, everything goes well and the COM object code gets executed without any errors. This is also the case when the application is hosted on an IIS 6 machine. I have looked through all settings of the IIS 7 and have not found anything configurable for COM objects, like security or ... I have been struggling with this for a while and I'm out of ideas. Does anyone have any experience deploying COM objects on IIS 7? Your help would be very appreciated!

  • Create Out-Of-Process COM in C#/.Net ?

    - by Huck
    Hi, I need to create an out-of-process COM server (.exe) in C# that will be accessed by multiple other processes on the same box. The component has to be a single process because it will cache the information it provides to its consumers in memory. Note: the processes that will access my COM Server are mostly Matlab processes, thus the necessity for a COM interface. I have seen threads regarding creating in-process COM components in .Net on stack overflow (Create COM ...) and on the web, but am having a hard time to find a way to create out-of-process components with .Net. How is this achievable? Any suggested references? Thanks.

  • CPanel - Wild card SSL - How to point *.domain.com to one root and sub.domain.com to another root

    - by Harry Muscle
    I have a wildcard (*.domain.com) SSL certificate installed on my CPanel server. I have domain.com configured to point to /domain.com as its document root and use this wildcard SSL certificate. I also have sub.domain.com configured to point to /sub.domain.com as its document root. Btw, I have not explicitly configured configured sub.domain.com to use the wildcard SSL certificate. When I go to "http://sub.domain.com" it goes to the correct document root, however my problem is that when I go to "https://sub.domain.com" it goes to the incorrect root, it goes to the root configured for the wildcard SSL. I've been trying to find information on how to go about configuring sub.domain.com to use the SSL certificate and go to the correct document root, however, so far I haven't found anything concrete. Do I use the same steps that I used for configuring the certificate for domain.com, but use the same certificate again and specify dev.domain.com as the domain that this certificate is for (instead of *.domain.com)? Or is there something else I should be doing? This is a production server, so I don't want to play around too much. I'm hoping to find the correct information before proceeding.

  • Can WPF based ActiveX control use Reg-Free-COM

    - by embnut
    I have a WPF based ActiveX control (COM interop). I am able to use it correctly by registering the control. When I tried to Reg-Free-COM (using manifest files) the control seems to be activated, but the events (such as mouse click, RequestBringIntoView etc) dont respond. Interestingly, Double click and tab key works. I read in the this article http://blogs.msdn.com/karstenj/archive/2006/10/09/activex-wpf-gadget.aspx that " ... These upsides come with a price: the ActiveX control must be registered in the registry, which requires some kind of installation such as an .msi. The default gadget installation process cannot install ActiveX. The ActiveX control can't be access via reg-free COM. ..." Has anybody had a similar experience? Can anyone explain what is going on? Additional details: When the control is activated after it has been registered it appears as part of the COM client's UI. The control does not receive focus, its elements receive it. When using reg-free-com the control does not load correctly. 1) The control receives focus instead of its sub elements 2) The control has areas that are black instead of the windows default color 3) when I tab in and out of the control or double click it, it's subelements receive focus, the control starts receiving events and the black areas are replaced by the correct color

  • Redirect www.example.com/apple to food.example.com/fruits/apple

    - by Senthil
    I want to redirect users from www.example.com/apple to http://food.example.com/fruits/apple Note: This is a hardcoded redirection. Even a mapping if you will. "apple" will not be substituted with anything else. Nothing in the two URLs will change except for the domain of course. So there is no need for a regular expression to match the "apple" or anything else. There is already dozens of RewriteCond and RewriteRule things in the .htaccess file. I do not want them to be affected. This redirection is independent of those. I have access to the .htaccess file at the root of www.example.com and the httpd.conf What code should I put in .htaccess in order to achieve this? Or should I change the httpd.conf?

  • How to configure DNS so that www.example.com goes to one server, *.example.com to another

    - by fishwebby
    I'm trying to set up my domain as follows, but I'm not actually sure if it's possible. I have a domain where I would like the base and www addresses to go to my static site, but others to go to my application server. For example: My domain is registered with Dreamhost, and my application is on a VPS at Webbynode. I've set up the domain in Dreamhost to use Webbynode's nameservers: ns1.dnswebby.com ns2.dnswebby.com ns3.dnswebby.com And in Webbynode I've set up a wildcard A record to point to the IP address of my VPS: * 1.2.3.4 A and this works nicely, if I go to app.example.com it resolves to my application server at Webbynode. However, what I'd like to do is have example.com and www.example.com go to my static site, hosted back at Dreamhost, whilst still having any other domain go to my app. What I've done to try and achieve this is set up these DNS "NS" entries at Webbynode, trying to get Dreamhost to resolve these domain names: (empty) ns1.dreamhost.com NS (empty) ns2.dreamhost.com NS (empty) ns3.dreamhost.com NS www ns1.dreamhost.com NS www ns2.dreamhost.com NS www ns3.dreamhost.com NS (I don't have a fixed IP address at Dreamhost so I can't just set up simple A records). However this doesn't work... does anyone have any idea if this is possible and if so how it could be done? Update: I've got this working now, as above for the domain (i.e. registered with Dreamhost, but using Webbynode's nameservers). To delegate the DNS for www.example.com to Dreamhost, I've got the following DNS entries set up: www.example.com. ns1.dreamhost.com. NS www.example.com. ns2.dreamhost.com. NS www.example.com. ns3.dreamhost.com. NS (note the full stops at the end) And to get example.com to resolve to my static site, I set up CNAME record: example.com. www.example.com. CNAME So now, example.com and www.example.com go to my static site on Dreamhost, and if they change the IP address of my shared hosting it won't affect me, and all other subdomains go to my application server. This seems to work nicely, but if anyone knows a better way to do it I'd be happy to hear it. Thanks to all who replied.

  • PHP: Cookie only sent to http://www.xxx.com and NOT http://xxx.com

    - by Axel
    Hi, I have a php login which sets 2 cookies once some one login. the problem is that if you login from : http://www.mydomain.com and you go to http://mydomain.com you will find your self not logged in, I think that's because the browser only send the cookies to the first syntax. It's only one domain, the difference is the www. before the domain name, so how to set cookies to the whole domain whatever there is www. or not ? Thanks

  • Monitor a COM port already in use.

    - by rross
    Is it possible to read from a COM port already in use on Windows XP? I would like to see the communication between some software and a device plugged into a serial device. I wrote a small program using C# to monitor the COM, but once it's in use by the other device it will not let you open it again. How can one monitor a COM port already in use? I'm open to 3rd party software. Thanks

  • .NET COM Interop with references to other libraries

    - by user262190
    Hello,I'm up against a problem when loading a class in a managed library from a COM Interop library. basically I have some Unmanaged C++ code and a COM Interop library written in C#. And finally a 3rd library which is referenced by the COM Interop library which contains a class: public class MyClass{ public MyClass(){} } What I'd like to do is from my unmanaged c++ code, call a function in the Interop library The C++ code doesn't need to know of the existence of the third library, it's only used within the Interop. Init(){ MyClass _class = new MyClass(); } for some reason this line in Init fails "MyClass _class = new MyClass();", and I don't get very usefull error messages, all I have to go on is a few of these in my output window: "First-chance exception at 0x7c812afb in DotNet_Com_Call.exe: Microsoft C++ exception: [rethrow] at memory location 0x00000000.." and the HRESULT of the "HRESULT hr = pDotNetCOMPtr-Init();" line in my C++ code is "The system cannot find the specified file" I'm new to COM so if anyone has any ideas or pointer to get me going the right direction, I'd appreciate it, Thanks

  • .NET COM Interop on Windows 7 64Bit gives me a headache

    - by Kevin Stumpf
    Hey guys, .NET COM interop so far always has been working quite nicely. Since I upgraded to Windows 7 I don't get my .NET COM objects to work anymore. My COM object is as easy as: namespace Crap { [ComVisible(true)] [Guid("2134685b-6e22-49ef-a046-74e187ed0d21")] [ClassInterface(ClassInterfaceType.None)] public class MyClass : IMyClass { public MyClass() {} public void Test() { MessageBox.Show("Finally got in here."); } } } namespace Crap { [Guid("1234685b-6e22-49ef-a046-74e187ed0d21")] public interface IMyClass { } } assembly is marked ComVisible as well. I register the assembly using regasm /codebase /tlb "path" registers successfully (admin mode). I tried regasm 32 and 64bit. Both time I get the error "ActiveX component cant create object Crap.MyClass" using this vbscript: dim objReg Set objReg = CreateObject("Crap.MyClass") MsgBox typename(objReg) fuslogvw doesn't give me any hints either. That COM object works perfectly on my Vista 32 Bit machine. I don't understand why I haven't been able to google a solution for that problem.. am I really the only person that ever got into that problem? Looking at OleView I see my object is registered successfully. I am able to create other COM objects as well.. it only does not work with my own ones. Thank you, Kevin

  • How to use an out-of-process COM server without its tlb file

    - by Dbger
    It is about Window COM component. Server.exe: an 32bit out-of-process COM server CLSID_Application: The GUID of a COM object in Server.exe Client.exe: a 64bit client application which use Server.exe in a registry-free way. As we know, an exe can't be used as a registry-free COM component, to mimic such behavior, I start the Server.exe process myself by providing the exact path: CreateProcess("Server.exe") IClassFactory* pFactory = CoGetClassObject(CLSID_Application) pFactory-CreateInstance(ppAppObject); It works if I have the Server.tlb registred, but after unregister Server.tlb, it just failed to create the ppAppObject, even though I embed manifest into both Server.exe and Client.exe: <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <file name="Server.tlb"> <typelib tlbid="{DAC4A4C9-F84C-4F05-A7DC-E152869499F5}" version="1.0" helpdir=""></typelib> </file> <comInterfaceExternalProxyStub name="IApplication" iid="{D74208EA-71C2-471D-8681-9760B8ECE599}" tlbid="{DAC4A4C9-F84C-4F05-A7DC-E152869499F5}" proxyStubClsid32="{00020424-0000-0000-C000-000000000046}"></comInterfaceExternalProxyStub> </assembly> Do you have any idea on this? Edit: It turns out that it really works if I specify tlbid for interfaces, and embed the manifest to both exe

  • Need to call COM component using reflections in C#.NET

    - by Usman
    Hello, I need to determin the COM component(unmanaged code) type and invoke the exposed interface's methods using reflection in C#.NET at runtime. 1 -- First What member of "Type" tells that type is COM component and we can take CLSID at runtime? Is Type.COMObject? 2 -- I need to call methods of exposed interfaces as they called in unmanaged code using CoCreateInstance by passing CLSID and REFID ... I am using InvokeMember but it returns null or 0 as out parameter. How to pass out parameter in this case.? Is there any need to pass out parameter? As all my COM unamanged code suppose to take las parameter as an OUT parameter and after executing it puts the result into that out param. But I've converted all my unmanged COM code to .NET managed assemblies using tlbimp.exe. Regards Usman

  • Fastest way to call a COM objects method without using a RCW

    - by Nathan W
    I'm trying to find the cleanest and fastest way for calling a COM objects methods. I was using a RCW for the object but every time a new version of the third party COM object comes out its GUID changes which then renders the RCW useless, so I had to change and start using Type mytype = Type.GetTypeFromProgID("MyCOMApp.Application"); so that every time a new version of the COM object comes out I don't have to recomplie and redeploy my app. At the moment I am using refelection like mytype.InvokeMemeber but I feel it is so slow compared to just calling the RCW. How does everyone else tackle the problem of changing 3rd party COM object versions, but still maintaining the speed of a RCW?

  • COM C# Memory leak Tracing

    Is there a way to find out the memory usage of each dll within a c# application using com dll's? Or what would you say is the best way to find out why memory grows exponentially when using a com object (IE. Whether the COM object has a memory leak, or whether some special freeing up of objects passed to managed code has to occur(and/or how to do that)).
