Currently in VB6 I'm using API's such as GetWindow (to get window Owner), GetWindowLong (to get window 'Styles'), etc. to obtain information about VB.NET application windows so I thought there may be a way of using an API to somehow determine the active MDI but perhaps not!<br />

Hi guys,<br />
<br />
I have a VB6 application that interacts a VB.NET application. From VB6 application I'm able to determine VB.NET application's main/MDI container window handle but I'm unable to determine its active MDI child window handle, i.e. the equivalent of &nbsp;&quot;Me.ActiveMdiChild' in VB.NET.<br />
<br />
I've tried using GetForegroundWindow and GetActiveWindow API's (from VB6 after using SetForegroundWindow API to VB.NET application) but neither return the correct value. The GetForegroundWindow returns main/MDI container window handle and GetActiveWindow returns 0.<br />
<br />
Thanks<br />

How to determine VB.NET application's active MDI child window handle from VB6

Programming includes both the specifics of the language you’re using, like Visual Basic, .NET, Java and others, but also the best practices in user experience and interfaces and the management of projects, version control and development. Other programming topics are related to web and cloud development and system and hardware programming.

Programming

Visual Basic is Microsoft’s event-driven programming language and integrated development environment (IDE) for its Component Object Model (COM) programming model. It is relatively easy to learn and use because of its graphical development features and BASIC heritage. It has been replaced with VB.NET, and is very similar to VBA (Visual Basic for Applications), the programming language for the Microsoft Office product line.
