Has anyone ported IJG JPEG code to C#? Are there any purely-managed JPEG libraries with source available? I don't much care about the license, as I just want to use it as a learning experience, not actually use it. Performance isn't a huge issue either. I realize the BCL has ways of reading and writing JPEG files, this is mostly to s...

Hey I'm getting this weird error on some stuff I've been using for quite a while. It may be a new thing in Visual Studio 2010 but I'm not sure. I'm trying to call a unamanged function written in C++ from C#. From what I've read on the internet and the error message itself it's got something to do with the fact that the signature in my C#...
We have a .NET application which our customers consider too large for mass deployment and we would like to understand what contributes to our memory footprint and is it possible to do any better without completely abandoning .NET and wpf. We are interested in improving both Total Size and the Private Working Set (pws). In this question...

Hi, The frequency with which I am coming across the situation where I have to call native 32-bit code from a managed 64-bit process is increasing as 64-bit machines and applications become prevalent. I don't want to mark my applciation as 32-bit and I cannot obtain 64-bit versions of of the code that is being calling. The solution tha...
Hello, I am wondering if it is possible to set a breakpoint in C# code using ADPlus. I find several examples of config files but they always works with native code. Like this one: <ADPlus> <Breakpoints> <NewBP> <!-- Set the breakpoint on ExitProcess. --> <Address>kernel32!ExitProcess</Address> <Type>BP</Ty...
I am writing a very high performance application that handles and processes hundreds of events every millisecond. Is Unmanaged C++ faster than managed c++? and why? Managed C++ deals with CLR instead of OS and CLR takes care of memory management, which simplifies the code and is probably also more efficient than code written by "a pro...
Hello, we have a problem with our applications. We have recently upgraded our toolchain to Visual Studio 2010 and friends, it all works fine on Windows Vista + Windows 7 developer machines and Windows 7 customer machines. (all x86) Today we did a first installation to a client PC running Windows XP SP2 x86, and all applications linking ...
I have an NSTableView which is populated via a CoreData-backed NSArrayController. Users are able to edit any field they choose within the NSTableView. When they select the rows that they have modified and press a button, the data is sent to a third-party webservice. Provided the webservice accepts the updated values, I want to commit tho...

Greetings, First off, I am not a C++ developer, so please forgive my shortcomings.... I am attempting to take another developer's C++ unmanaged code and re-work it so it can be called from a managed DLL from our c#.net application. Please keep in mind that I'm a .net developer, and I haven't touched C++ in like 12 years. And when I ...

Is it possible to invoke cl.exe, the MSVC++ compiler, from inside a Visual Studio extension? I'm using VS2010 and not bothered about maintaining compatibility for 2008/2005. I've hunted through MSDN and had a poke through my DTE object, but not found anything of use. The documentation on what you can do with this stuff is kinda sparse. ...
I've searched on this issue, and found many flavors and ideas but no real solutions. So, donning my asbestos suit and hoping for the best, I'm going to dare ask it again. I have managed C# code that calls managed C++ code, which in turn calls unmanaged C++ code. The unmanaged C++ code is throwing an exception, and I'd like to be able ...
Hi Everyone, I am moving a few functions from a Managed C++ Winforms app to a class library so that I can call them in a new C# app I'm writing. However one of the functions returns a System::Drawing::Bitmap^ and uses the System::Drawing::Color class which is causing an error saying that System does not contain a namespace called Drawin...
Background We have a .NET library that is referencing one of our unmanaged dlls, lets say: DotNet.dll Unmanaged.dll Thus far, Unmanaged.dll is only 32-bit, so the DotNet.dll is marked with 32-bit CPU type. 64-bit support needs to be added. How to organize the dlls? IL code of DotNet.dll will be the same for both 32-bit and 64-bit ...
Hello there, I'm getting from our hardware device (FPGA) roughly 20 frames per second (500x500 px) and I would like to render them as fast as possible. We basically get a frame buffer every 50 msec and if my rendering is too slow - well... I'm skipping frames. My problem is to render from a C++/CLI driver to a WPF-based application. I ...
