• Visual C++ Dynamic References in C++/CLI

  I have several mixed mode assemblies compiled for both x86 and x64 and renamed as follows: MyDll1_x86.dll MyDll1_x64.dll MyDll2_x86.dll MyDll2_x64.dll etc. When using these from a C# project I have been able to simply adjust the reference to dynamically point to the appropriate DLLs by editing the appropriate line in the .csproj file to use the $(Platform) variable: <Reference Include="MyDLL1"> <SpecificVersion>False</SpecificVersion> <HintPath>PATH_TO_DLLS\MyDll1_$(Platform).dll</HintPath> <Private>False</Private> </Reference> <Reference Include="MyDLL2"> <SpecificVersion>False</SpecificVersion> <HintPath>PATH_TO_DLLS\MyDll ...Show All

• Gadgets SideBar Gadget and <object /> Tags

  I assume that SIdebar is using a mini-IE7 window to display themselves, but I can't seem to get an <object /> tag to work in my gadget. Any idea why that wouldn't work Before I spin my wheels understanding what is happening, I wanted to make sure that there wasn't a security prohibition to using an <object /> or a <embed /> tag. Sidebar doesn't natively support WPF applications, although the guys over there have written Sidebar Styler , which adds this capability. If you want to go the IFrame route: There's this article which includes sample code and pics. And here's a sample WPF Gadget. ...Show All

• Visual Studio Team System profiler says my project is creating a lot of strings, byte[] and type[]

  I have run the profiler to check what objects are being instantiated by my project and it says that I am creating an awful lot of strings, byte arrays and type arrays. A lot of them (50,000) are coming from an external library I am using (oradirect .net, an oracle driver) but there are also quite a few coming from the constructor of my usercontrol (10,000). My usercontrol is nothing huge just a couple of toolbars, grids and a tree, all with no data. I have emailed the people who write the oracle driver but their profiler (AQTime) but didnt find anything: http://www.crlab.com/forums/viewtopic.php t=9112 . Here are some screenshots of the problem, which also shows the byte and type arrays: http://www.kevinandkiran.com/screenshot ...Show All

• Visual C++ How to fix Incremental Link Error?

  Hi all, I implemented a basic client application. It communicates with server and works properly. Building processes succeed just by giving the following warning: LINK : D:\DOC\Visual Studio 2005\Projects\Client01\Debug/Client01.exe not found or not built by the last incremental link; performing full link This warning occurs when building/rebuilding the project after cleaning the intermediate and output files. If the project is once built then this warning is not given. In the solution, I have only one project consisting of the following files(I also added wsock32.lib to Project configuration as the Linker Input in order to use the socket functions): main.cpp MyMessage.h MyMessage.cpp MyConnection.h MyCon ...Show All

  I am writing a gadget to view daily comics. I would like to save the images to a local folder. Does anybody have any suggestions My gadget will display the comics I just need advice on how to save the images. Thanks. I'd forgotten about REGASM! Been a few years since I've touched .NET.

You can use it to get the registry keys: regasm.exe <file.dll> /regfile:myreg.reg I wouldn't use it in your Gadget though, as it requires privilages that a "User" doesn't have. ...Show All

  Hello, I try to make a class (called voltage) to use in a Usercontrol (called switch). I like to know when one of the propertys of the type voltage change by means of an event triggerd in the voltage class, and then trigger a event in the class switch to notify the user. (see also my last post) here is the code for the voltage class: Hmm, you declare the voltage objects using lowercase ('a', 'b', 'c') but you attach to the events using uppercase ('A.VoltageChanged' etc). This leads me to suspect that you haven't posted an actual copy/paste of the real code... ...Show All
