Right now my .NET macro is built for 188.8.131.521, I found that if I load it into earlier version of CorelDRAW X7 it would outright crash the whole program.
Is there a way to check CorelDRAW DLL Assembly version so that it would prompt user to update their CorelDRAW? I'm thinking that I should do this within VBA before calling the DLL, but I haven't found out how.
In VBA this simple code returns Corel Version:
You can use it in a corel Event...
You can check that using a VBScript:
Set Cor = CreateObject("CorelDraw.Application")
MsgBox "Corel " & Cor.Version, , "Corel Version"
Set Cor = nothing
Or directly in C# using Corel COM object or not. Using it in a similar way of VBScript or extracting from Registry the Corel.exe path and than the version of VGCore.dll in Assembly folder. Relatively easy...
Spot on, thank you.
In C# Addon you can modify the Constructor in Main entry
public partial class DockerUI : UserControl
private Corel.Interop.VGCore.Application corelApp;
public DockerUI(dynamic app) //use reflection for support any corel version
//Show a friendly message
this.corelApp = app as Corel.Interop.VGCore.Application;//cast for correct type, reflection will showdown your app
protected bool versionOk(string version)
//Make your check
Could this code run even though the addon is compiled with different assembly?
Yes this is Works in any versiion, but if you try cast a more new versiion for a older versiion you Will got a exceptiion
