• stephanielauym Cannot launch .NET from VB6 using Interop Toolkit

  Hi, I am trying to investigate the Interop Forms Toolkit but I seem to have run in to a problem. I have followed the docs on how to create a .NET forms interop assembly and I created a very simple form as a test. The form was correctly marked with the InteropForm attribute. I generated the wrapper classes fine. Everything builds. I create a new VB6 exe, added a reference to the Interop Forms toolkit and my custom .NET forms assembly. I added the relevant declarations for the InteropToolbox too. Intellisense is working as I could see my library and form types when declaring them. The problem is that when I execute the code below: Dim f as New SimpleForms.InteropForm I get an error: Runtime error: 429 ActiveX compo ...Show All

• markand Net Programs & Dual Core

  My .Net program uses 80-100% CPU (memory operations - no disk activity). If I get a dual core, could I run two instances without performance issues ...that is running each app on a single CPU. Thanks if your app takes 80-100% CPU then something is seriously wrong and would advise you to review your code. Getting a dual core will not solve the original problem :-) you probably would face the same problem at some point This is very interesting... thanks.  You learn something new everyday. Wait, we don't know anything about this application. Suppose it's the equivalent of SuperPi or does string arithmetic There may be something the OP is doing inc ...Show All

• rathlar Problem retrieving specified graphics files to form

  Hi, I have Bitmap files whose names are concatenated from a drawing and a reference number. I need to be able to retrieve all the files of drawings for a specific reference number. The following Do While loop will work using dwgNo as the condition, until the actual drawing number does not exist, at which time it naturally throws an exception.

• hrd2hndl67 Generate midi song from VB.net

  I use VB.net with Framework 2.0 How to generate a midi song from the code and save it as a *.mid file I am a beginner, so would be most rateful for simple enough instructions. The song should be polyphonic (max. 2 notes at the same time). I should be able to set the pitch and duration of the notes. The code should support rests (= pauses in the song or kind of a "empty notes") and I should be able to set the tempo of the whole song. Is this possible at all Also a simple midi piano would solve my problem. There are many for VB6.0 but I haven't found even a single one for vb.net!

• mdh. Passing Pointer to an Array in VB

  I have an array i have to pass the array as a pointer. WIllfin Arrays are reference types which are marshalled differently between managed and unmanaged code. (see ms-help://MS.VSCC.v80/MS.MSDN.v80/MS.VisualStudio.v80.en/dv_fxinterop/html/049b1c1b-228f-4445-88ec-91bc7fd4b1e8.htm) Since you specify you are doing this in VB, it shouldn't be a problem but could get tricky if dealing with interfacing with API's. To pass a parameter to a method, you can either pass it ByVal or ByRef. The other trick is being aware of what you are passing. In the case of a simple Integer, passing it ByVal means passing a copy of it where-as passing it ByRef means passing a pointer to the memory containing the integer. Th ...Show All

• qjay VB2005 Upgrade, or not?

  Hello, I am not sure if this is the right place to ask this question, but I couldn't find anything more fitting. I am considering getting the Visual Studio 2005 IDE, but I have a reservation. I currently have VS2003, and have heard that the .NET 1.1 framework is falling by the wayside, so to speak. I have used the trial version of VS2005, and like it very much. However, I have heard that VS 9.0 will come out soon, and I don't want to have to upgrade again in a year or two. So, I guess my question is, is VS2005 going to be viable long enough to make it worth the purchase Is Microsoft making the higher level languages like Visual Basic "disposable", in other words, changing every few years Please, don't take me as being an ...Show All
