vb6-migration

问题 This code was converted from VB6 to VB.Net: Public prvMainForm = VB6Form If prvMainForm IsNot Nothing Then CObj(prvMainForm).StatusBar.Panels(1) = "Initializing Folders..." End If (My code is quite long so I've just added this if block which is where the actual error occurs.) The error is seen on the single line inside the If statement: Property 'Item' is 'ReadOnly' 回答1: StatusBar.Panels(1) returns a MSComctlLib.Panel . StatusBar.Panels(1) = "Initializing Folders..." is valid in VB6 because

问题 I have the following code in vb - tAvailableDate = DateAdd("d", 21, Format(Now, gDATEFORMAT)) I am attempting to convert this into C#. I have converted this so far - tAvailableDate = DateAdd("d", 21, Format (DateTime.Now, Global.gDATEFORMAT)); But I cannot find a replacement for the DateAdd() or Format() feature. Any ideas? Thanks. 回答1: DateAdd is an old VB6 method that was carried over into VB.NET for backwards compatibility. You could get it to work in C# as well if you included the

问题 I explain my problem : I have some program (5-6) in vb6, and a lot of DLL in vb6. We will perform a migration of these DLL and program in Vb.Net. We want to start with DLL, and each program references 2 or 3 DLL. I want to perform the migration of the DLL in vb.net (no problem for that) but i want to keep the (binary) compatibility between my old vb6 DLL and the new one in vb.net Because without that i will have to re build each application using this DLL because the compatibility is broken.

问题 I would like to be able to code a class interface which I can implement in C# and VB6 classes so that these classes can be handled in the same way within VB6 code but I can't make this work. In VB6 I want to have come class VB6Class using the Implements key word to implement some interface ISharedInterface. In C# I want to have some other class C#Class which I can expose to COM as also implementing ISharedInterface. The goal is that VB6 code will then be able to operate on VB6Class and C
