Using Microsoft Office objects in VB.NET projects with Option Strict On, just using an Office type library enum like this:

Developing two new Office VSTO add-ins, one for Microsoft Excel and Visio, I ran in to this particular issue.

I have a strong preference to develop in VB.NET with Option Strict On, for the simple reason that it is good practice and saves me a ton of debugging later.

However, a lot of Office object methods like this one for Visio: https://docs.microsoft.com/en-us/office/vba/api/visio.page.getresults

were designed for passing (VBA) Variant Arrays back and forth ByRef (ugh!).

(Because the .net COM interop is quite slow these bulk methods are necessary for a good user experience)

I know how to create these arrays in VB.NET to work across the interop, like:

I'm trying to automate the creation of network diagrams via Powershell and Visio but, I'm at a roadblock. I want to change the color of the Cloud (built-in Visio shape) but for some reason, the color does not change. Can you please help me solve this issue? (See code below)

I am trying to make a layer in Visio visible through an Excel Macro, that I wrote. However, I always an invalid parameter error.

This is my code:

I wrote a macro in Visio to retrieve the value for the shape property field index, but the row value keeps changing from shape to shape (sometimes 5 and sometimes 8). However, I can't find a way to replace the value 5 in CellsSRC with a solution that focuses on the row name rather than the row value. Any suggestions how I can find the value for the property "Index"?

This is my macro:

I have written a python program in Visio code and I found a strange Behavior

code:

I wrote two macros in MS Visio. The first macro hides all layers, the second macro selects a specific layer to be shown. Both macros work fine by themselves, but when I try to run the first macro in the second macro I received a compile error, that the sub cannot be found. Any ideas on how to call the private sub correctly?

First sub, which hides all layers: Private Sub Deselect_layers()

I'm trying to drop/draw/insert a command button into a Visio page and set its text using VBA.

Currently I'm able to insert the button using the following VBA, but I'm not finding any way to edit the text.

I have checked multiple links and two options were shown for editing MS visio file in Java code.

1. Apache POI - HDGF and XDGF - Java API To Access Microsoft Visio Format Files

2. Aspose.diagram APIs

Has anyone done any coding in Java language using above option? I am using eclipse IDE.

Also please suggest if there is third better way to edit MS visio file using java code.
