问题 I'm trying to recreate a program that uses javascript to open a connection to a PLC and then display all sorts of information on a web page. I'd rather have it in a form in MS Access for various reasons, and have spent forever trying to find the right dll to use (Jet32X.dll, if anyone is curious). I finally tracked the CLSID called out in the javascript back to a registered class for the PLC, and I'm trying to create that object in VB code. It won't get any further than the Dim As New line,

Visual Studio diagnostic tools not displaying process memory

阅读更多关于 Visual Studio diagnostic tools not displaying process memory

I have a VB.NET app (with C# libraries) which is consuming large amounts of memory over time. Ultimately the application runs out of memory. I am cautious about using the term leaking because the GC shouldn't allow a memory leak, but perhaps there is a large .NET object somewhere. If so I need to identify it. However I do have a reference to a 3rd party ActiveX control library (.ocx) of which I use some controls and make numerous calls retrieving laser beam profile data. Memory usage increases only when I run a loop retrieving the laser beam profile data from the ocx. I suspect the ocx but

I have also referred to this article to create ActiveX object and have implemented an ActiveX dll that I am calling from browser to launch an application on client side..

C#: Loading an embeded swf into an flash activex without a temporary file

阅读更多关于 C#: Loading an embeded swf into an flash activex without a temporary file

My project requires that my final application be completely self contained in a single exe. I am already combining the executable and dlls using ILMerge (assmebly merge utility). I am hosting an flash active x control in a C# application and I have embedded the one swf i need to load into the flash control into the c# application as an embeded resource. This question shows how to write the resource to a temporary file , but it is undesirable to create temporary files for my situation. This creates a problem because the active x control loadMovie method only accepts a string pointing to the

Building an OCX with VS.NET?

阅读更多关于 Building an OCX with VS.NET?

问题 What happened to OCX's? Are they no longer possible to create with the latest tools? I need to create an ActiveX control that I can place in Word, PowerPoint and Excel documents. If I use VS.NET, I can only create a UserControl DLL with COM Interop, but I don't think I can add that using the "More Controls" toolbox of PowerPoint's Developer Tab. What would you do? 回答1: Yes, you can still create them. But you can't create an OCX with a .NET language. Need to be unmanaged C++ (or VB). The DLLs

I would like to create an activeX control(OCX) in VB .net 2010 is it possible? I having a hard time determining how to make it because I only get a .dll file rather than a .ocx which can be seen in vb6. I hope you can answer my question. Are you asking how to create an "ActiveX" control specifically or are you asking how to create controls that can be used by other CLR based applications? To create an ActiveX control, see this link which walks you through the steps to do this: Creating an MFC ActiveX Control To create standard controls, you use a dll (class library) and can add as many
