I need to access code in a native C++ DLL in some C# code but am having issues figuring out the marshaling. I've done this before with code that was straight C, but seem to have found that it's not directly possible with C++ classes. Made even more complicated by the fact that many of the classes contain virtual or inline functions. I...
The only thing that I found was Manzana but it crashes while I start the test executable. Can someone tell me some library which can I use to copy/delete files from and to iPhone? Or maybe a console tool which I can use as a back-end. ...

hi I have a COM object that takes needs to take a stream from a C# client and processes it. It would appear that I should use IStream. So I write my idl like below. Then I use MIDL to compile to a tlb, and compile up my solution, register it, and then add a reference to my library to a C# project. Visual Studio creates an IStream defin...
I've got a native C++ DLL that I would like to have a C++/CLI wrapper layer for. From what I understood, if you simple added a C++/CLI class to the project, VS would compile as mixed mode, but I was apparently wrong as VS doesn't seem to be even touching the managed code. So, given a pre-existing native code-base what exactly, step-by-...
I have the following routine that dumps a DataTable into an Excel worksheet. private void RenderDataTableOnXlSheet(DataTable dt, Excel.Worksheet xlWk, string [] columnNames, string [] fieldNames) { // render the column names (e.g. headers) for (int i = 0; i < columnNames.Len...
static void Main() { Application excelapp = new Application(); Workbook book = excelapp.Workbooks.Open(@"C:\HWYFAB.xlsx", 0, false, 5, "", "", false, XlPlatform.xlWindows , "", true, false, 0, true, false, false); Worksheet sheet = (Worksheet)book.Sheets[1]; Range cell = (Range)sheet.Cells[3, 2]; Console.WriteLine(cel...
I have an application that generates Open XML documents with Content Controls. To create a new Content Control I use Interop and the method ContentControls.Add. This method returns an instance of the added Content Control. I have some logic that saves the id of the Content Control to reference it later, but in some computers I've been ...
Trying to get a reference to the worksheets (using Excel interop): Excel.Application xl = new Excel.ApplicationClass(); Excel.Workbooks xlWorkBooks = xl.Workbooks; Excel.Workbook xlWorkBook = xlWorkBooks.Open(fileName, 0, false, 5, "", "", true, Excel.XlPlatform.xlWindows, "\t", false, false,...
I have some windows docked to edges/corners of the working area, and I need to know if/when the WorkingArea of the screen changes so I can update the position of those windows. I've attempted to tackle this before to no avail, as I recall. ...
When I try to instantiate a PDF browser control like this in C#: AcroPDFLib.AcroPDFClass acrobat = new AcroPDFLib.AcroPDFClass(); I get a COMException with this message: Creating an instance of the COM component with CLSID {CA8A9780-280D-11CF-A24D-444553540000} from the IClassFactory failed due to the following error: 80004005. ...
I have a C# COM server which is consumed by a cpp client. One of the C# methods returns a string. In cpp the returned string is represented in Unicode (UTF-16), at least according to the memory view. Is this always the case with COM strings? Is there a way to use UTF-8 instead? I saw some code where strings were passed between cpp an...
In F#, there's the NativePtr module, but it seems to only support 32 bit offsets for its’ add/get/set functions, just like System.IntPtr does. Is there a way to add a 64 bit offset to a native pointer (nativeptr<'a>) in F#? Of course I could convert all addresses to 64 bit integers, do normal integer operations and then convert the resu...
Hello, all. I am messing around with the WMPLib component provided by Windows Media Player 12 (wmp.dll) in VB.NET with .NET Framework 3.5 SP1. I am trying to retrieve a media item from my media library based on its name (assuming there are no duplicate names). At the moment, I'm grabbing the entire media library, and looping through ev...
When C# app is ran, it POSTS a request to the PHP server, which wants to return an array. What's an easy way to load this array's contents into C# for using with there. For clarification, this array is a PHP stdClass object that contains strings, floats, and other stdClass objects. I want to get a similar data structure on the C# end ...
I'm trying to use code similar to clrdump to create mini dumps in my managed process. This managed process invokes C++/CLI code which invokes some native C++ static lib code, wherein SEH exceptions may be thrown (e.g. the occasional access violation). C# WinForms -> C++/CLI DLL -> Static C++ Lib -> ACC...

Hi, I'm at my wit's end with this. What I'm doing is making a C# dll file that needs to have some methods exposed to FoxPro 8. This guy here http://www.west-wind.com/presentations/VfpDotNetInterop/DotNetFromVFP.asp says that you can put [ClassInterface(ClassInterfaceType.AutoDual)] in front of the (C# in my case) class, and then intell...
