问题 I have a legacy VB6 application that calls a VB6 DLL, and I am trying to port the VB6 DLL to C# without yet touching the main VB6 application code. The old VB6 DLL had one interface that received a VB6 long (32-bit integer) by reference, and updated the value. In the C# DLL I have written, the updated value is never seen by the main VB6 application. It acts as though what was really marshalled to the C# DLL was a reference to a copy of the original data, not a reference to the original data.

问题 Does anyone know of a good reference for VB6 format-strings? Does anyone know of a converter from VB6 formatting strings to .NET strings? I'm working on porting a large VB6 code base to .NET. It is a database centric piece of software, and the database itself holds VB6 format-strings which are later loaded and used to display other data in the database. My question, like this article, is how to port this. However the answer chosen for that question isn't adequate for my needs. I'm

问题 I have a large VB6 app which I want to convert to C#. The majority of the code in VB6 is quite badly written. I thought that a good strategy would be to keep the GUI design since it is adequate and would be a pain to recreate. But I would want to rewrite the code behind the GUI and the data layer. I could keep the GUI design by using one of the VB6 to .NET converters provided by Microsoft. Would this be a good strategy? 回答1: There are several migration tool to perform a migration from VB6 to

问题 I am upgrading user control from vb6 to vb.net. In the vb6 application I am loading 3000 labels using a label control array. In vb.net I am doing same but it's taking too much time to load. In vb6 it's taking 1-2 seconds, but in vb.net it's taking 30-40 seconds for same work. What is problem? Why does it take too much time in vb.net for same work?

问题 Is the VB6 to .NET upgrade wizard included in VS2008 better than the one in VS2005? UPDATE: I ran the same VB6 code through both upgrade wizards and VS2008 produced far less reported issues in the ugprade report. The upgrade wizard in VS2008 must be an improved version. 回答1: Both VS2005 and VS2008 use the same convertion utility. 来源： https://stackoverflow.com/questions/8194038/which-is-better-vb6-to-net-converter
