C# UDP Socket client and server

阅读更多关于 C# UDP Socket client and server

问题 My first question here. I am new to this kind of programming, and i've only programmed .NET web sites and forms. Now, the company I work at, asks me to make an ActiveX component, that listens to UDP messages, and turns them into events. The UDP msgs are send from Avaya system, so i was told that to test my ActiveX, at first I need to create an app, that only sends UDP (only one button that sends pre-defined UDP string).

C# COM DLL: do I use Regasm, or Regsvr32?

问题 I am building a C# ActiveX DLL... do I use REGASM or REGSVR32 to register it? How do I register the 64-bit interface vs the 32-bit interface? 回答1: You need to use regasm.exe to register both the 32 bit and 64 bit interfaces I believe you need to run each of the regasm.exe 's in: C:\Windows\Microsoft.NET\Framework\v2.0.50727 and C:\Windows\Microsoft.NET\Framework64\v2.0.50727 So... in your case you need to run the regasm.exe in the Framework64\v2.0.50727 folder. Here's an example we use to

问题 I am desperately trying to deploy an ActiveX for IE developed in C# as a CAB archive. I have read many resources (some of them from StackOverflow) and it appears a lot of people are having the same problems. I have tried 3 solutions: a) creating a CAB VS project, b) manually creating a CAB using CABARC with a COM registration in INF and c) manually creating a CAB with launching msiexec . None of them worked. I even tried d) creating a bootstrapper which launches msiexec to no avail (because

问题 This thread discusses a problem I've been having with ActiveX objects in an Excel spreadsheet. It's a mess to read through and ultimately doesn't have a cohesive answer. The problem is 100% reproduceable: Open workbook with ActiveX objects in spreadsheet while using a docking station Disconnect machine from docking station, triggering a resolution change (there are other causes too, mine is with a docking station, it seems changing resolution causes this) Click an ActiveX control - they

问题 I'm seeing a few questions related to this on SO already, but I think mine is sufficiently different to not be considered a duplicate (if I'm wrong let me know). I have an ActiveX control I've written in C# and while I have it mostly working, I want to raise an event in JavaScript when it's clicked (it displays an image so it's a visual element on the page). The end goal of what I'm looking to accomplish is no different than if it were a <span> tag and it had an onclick event to raise a

问题 I\'ve read that it is possible to automate monthly reports in Crystal Reports with COM/ActiveX. I\'m not that advanced to understand what this is or what you can even do with it. I also do a lot of work with Excel and it looks like you also use COM/ActiveX to interface with it. Can someone explain how this works and maybe provide a brief example? 回答1: First you have to install the wonderful pywin32 module. It provides COM support. You need to run the makepy utility. It is located at C:\...

IE11 prevents ActiveX from running

阅读更多关于 IE11 prevents ActiveX from running

问题 Our web browser plugin works fine in IE9 and IE10 but in IE11 the plugin is neither recognized as an add-on or allowed to run. It\'s as if IE11 no longer supports ActiveX. Surely there is a workaround but what do we need to change? NOTE: this questions is asked as the developer of the plugin and not the end-user who might need to correct IE settings! 回答1: IE displays a active x warning and ask for permission if you allow it to run or not. To overcome this the only solution is to; Open
