I've been testing an application using my machine as a server, and everything's going fine with it, but when I try to set it up to run on the test server, I get this error: Retrieving the COM class factory for component with CLSID {XXXX} failed due to the following error: 80040154. Any ideas? Thanks ...
I have a COM SDK written in C++ and I'd like to create documentation for my product. I understand that most people will probably not use C++ for integration with this COM component, but many will. Which method is best to describe the API, without losing details that a C++ developer would need to know. ...
What interop signature would you use for the following COM method? I am interested particularly in the final two parameters, and whether to try to use MarshalAs with a SizeParamIndex or not. HRESULT GetOutputSetting( DWORD dwOutputNum, LPCWSTR pszName, WMT_ATTR_DATATYPE* pType, BYTE* pValue, WORD* pcbLength ); Doc...
I am trying to call a COM object from PHP using the COM interop extension. One function requires an OLE_COLOR as an argument? Is there any way to pass this kind of value from PHP? I have tried passing a simple integer value with no success. $this->oBuilder->Font->Color = 255; ...
I have been searching high and low for a way to get my silverlight application talking to the COM port on my local computer. Has anybody out there been able to get Silverlight to successfully connect to the COM port of you local computer? If so can you point me to the documentation. ...
Hi all, I've got a WinForms .Net app that runs over a lot of XPS documents (thousands) and during this run the number of handles (according sysinternals process monitor and task manager) increases by between 3-10 for each document. I heavily suspect that these are handles that are opened and not closed by the MS .Net XPS framework libra...
I have a C++ app in VS2005 and import a VB DLL. IntelliSense shows me all the symbols in the DLL as expected but it also shows all (or nearly all) of them again with an underscore prefix (no @s in them though). Why is this? What are the differences between the underscored items and the normal items? ...
I have created a .NET DLL which makes some methods COM visible. One method is problematic. It looks like this: bool Foo(byte[] a, ref byte[] b, string c, ref string d) VB6 gives a compile error when I attempt to call the method: Function or interface marked as restricted, or the function uses an Automation type not supported ...
Hello, Im currently using ie as an active x com thing on wxWidgets and was wanting to know if there is any easy way to change the user agent that will always work. Atm im changing the header but this only works when i manually load the link (i.e. call setUrl) ...
Is it possible to use an ocx (ActiveX Control) on a winform (probably adding it programatically) without first having the ocx registered with regsrv32? What I'm trying to achieve is to enable xcopy installation. I've had the "AxInterop..dll" and "Interop..dll" file generated from my dev machine. I've seen the possibility of calling a C...
I've seen with Microsoft COM and XPCOM, at least from what I've read and gathered so far, that the implementations of interfaces in a component have to essentially be in the single class that derives all the virtual interfaces. Is this correct? What am I missing? Is there a way to have multiple objects (possibly in separate DLL's) each ...
$sql = "INSERT INTO images (path, useremail, approved, flagged,caption,date) VALUES ('$target','$email',0,0, '$caption','$b')"; $sql1 = "INSERT INTO users (name, email, phone) VALUES ('$peoplename','$email','$phone')" $conn->execute($sql, $sql1); Above is the code Ι am using to try and write to 2 tables. Before Ι introduced connection ...
Here's the core problem: I have a .NET application that is using COM interop in a separate AppDomain. The COM stuff seems to be loading assemblies back into the default domain, rather than the AppDomain from which the COM stuff is being called. What I want to know is: is this expected behaviour, or am I doing something wrong to cause th...
After upgrading a VB 6 based application exposing a COM interface, COM Clients (in .NET) built against the previous version receive E_NOINTERFACE errors. The error message (translated) Cannot convert COM-object of type AProduct.AClass to interface of type AProduct._AClass ... What went wrong here? What is the cause of the E_NOINTERFA...
Hello, I am writing a toolbar for IE(6+). I have used the various sample bars from codeproject.com (http://www.codeproject.com/KB/dotnet/IE_toolbar.aspx), and have a toolbar that works, registers unregisters etc. What I want the toolbar to do is to highlight divs within an html page as the users' mouse moves over that div. So far the ...
I'm about to take on a project that requires a Firefox addon to issue call to COM dll's installed on the client Windows machine and I'm having a hard time estimating the complexity of this undertaking. I have quite a bit of experience with COM, so I'm not frightened by it. I have less experience with Firefox addons, but I don't think th...
I have an unmanaged C++ application that uses the COM ADOConnection object. The application makes use of the BeginTrans/CommitTrans methods on the object to control transaction behavior. I recently added a CLR stored procedure to do some Regex stuff (and got some wicked fast processing, much better than pulling the data back to C++, pr...
I am trying to get a definitive answer regarding the way COM behaves on a x64 machine. Does Windows use the normal x64 calling convention when dispatching calls to COM interfaces on x64 machines (assuming the COM implementation is 64 bits)? Specifically, I dynamically generate my vtbl entries to point to a chunk of assembly that's dynami...
Hi, I am developing a jsp application. I am forced to load a COM object. Can such a thing can be done? if yes, how?? Many thanks, Ofer ...
I have an OLE COM object that trying to write a wrapper for, I have decided to start to use TDD to write the code for it as I believe that it will give me a better sense of direction with what I'm try to write. The COM object has a interface like this: Interface Mapinfo Sub [Do](ByVal cmd As String) Function Eval(ByVal cmd As S...
