I am in the process of developing an ActiveX control for embedding in Rockwell Automation's Factory Talk View. (See ActiveX DLL Error: Solved to see how great a start I got off to!)
At the moment I have an ActiveX control that seems to embed into the host system OK, but is not fully integrated into the VBA process. I believe that this is because I have not implemented some specific COM interface that is required, but I have no documentation as to what that is. I do know that standard MS controls like the Microsoft Forms 2.0 controls do implement the required interface and fully integrate.
The key functionality I am missing relates to a property that I need to set in order for my VBA code to actually see the ActiveX object. This property can be seen when opening the property panel for any activeX control placed on a Factory Talk screen, but NOT when looking at the properties of ActiveX controls embedded in (for example) Excel. Thus I am probably trying to chase down some custom Rockwell implementation. I am hoping that SO might be able to give me some aid into how to track down what I want based on recognizing the functionality it implements.
Now to the actual property. In Factory Talk the property is called "ExposeToVBA", and has a type "long". You have a choice of 3 values selected from a drop down list:
Not Exposed - When set to this, the controls name is not even visible to VBA code
Type Info Extension - Not sure what this does
VBA Control - VBA code can see and interact with the control.
When I select anything other than "Not Exposed" for my control, I get a warning dialog box with no text on it. For other controls I need to set it to "VBA Control" in order to interact with it in the VBA code (d'oh)
I suspect that the value of this property is translated into some calls to an ActiveX interface on the target control.
The Question
What I want to do is identify what interfaces something like a "Forms 2.0 Label" implements that would match the above functionality. And also perhaps how I could translate this into my C# based control (based on C# ActiveX control (CSActiveX))
I know its a long shot, but I'd appreciate any and all suggestions
This became moot when I found a canned Active-x control that had the functionality that I needed.
FWIW This is what I believe that I used: DMGraph

everyone,
I am new to VBA and would like to know if it is possible to execute a menu button from a WordAddIn.
In the picture you can see which button I would like to execute using VBA.
Unfortunately, I can't record it via macro.
The Word object model allows executing built-in ribbon controls using the CommandBars.ExecuteMso method which executes the control identified by the idMso parameter. This method is useful in cases where there is no object model for a particular command. Works on controls that are built-in buttons, toggleButtons, and splitButtons.
But in your case the control comes from a third-party add-in which doesn't expose IDs and the CommandBars.ExecuteMso method can't find it and invoke the command programmatically.
To get the job done you may consider using the Microsoft Active Accessibility which is a Component Object Model (COM)-based technology that improves the way accessibility aids work with applications running on Microsoft Windows. It provides dynamic-link libraries that are incorporated into the operating system as well as a COM interface and API elements that provide reliable methods for exposing information about UI elements.
Also you may contact the add-in vendor for providing public methods that can be called from your solution. That's also a possible workaround instead of calling UI elements on the ribbon.
I am currently working on an PowerPoint Addin and I am currently finishing the Ribbon. I'd like to create a control to change the size of objects that looks similar to the inbuild button "ShapeWidth" and "ShapeHeight":
However, I couldn't find the correct control type and hence I built the below by myself using an editbox and buttons. Although it's working I find the other style way cleaner but I haven't found the correct type.
Not all Ribbon X (Office Fluent UI) control types that Microsoft uses in its Office applications are made available to third-party developers. This, I'm afraid, falls into that category.
You should probably be able to get the image, at least, by specifying the idMso for the built-in control.
So I've made the following control in Design Mode then added the control to a new page Custom in my toolbox.
Now, what would I use for the progID parameter in Controls.Add()? How do I look up this value? Controls.Add("Forms.Frame.1") adds a regular frame, not the desired custom control.
As far as I am aware, you do not generate a new progID with a custom control. Per the MSDN documentation for custom/modified controls:
Note: When you drag a control onto the Control Toolbox, you only transfer the advanced property values.
So only the properties are transferred; the actual control is still of the same type/s as the one you created it from. Further, it looks like this progID is "a unique system-wide string that the Windows operating system can use to identify your control's type." So unless you are up to coding your own control, it looks as though you're just passing properties to the custom toolbox controls you create there.
You'll have to just replicate the custom control each time you want to add it. Just create a sub with all the correct properties and call it. Not what you were looking for, but it'll get the job done.
new to .net coming from vba decided to rewrite a management app using vb.net and SQL Server.
Started writing the base library for my application.
I created custom controls to use in my application that would expose a Zoom function, background color for the current active control a .modified property similar to the one available in textbox and some extra other properties (SQLTableName, SQLColumnName, ...) to enable iterating through a container (form) for modified controls and Update/Insert into a SQL table via a SQLProcessClass.
Concurrently I'd like to also implement a simple undo functionality.
My first idea was to add a PrevValue variable set in the OnEnter event if the Modified property is False, exposing an OldValue property and an Undo method in the custom controls.
However I found that the TextBoxBaseClass already exposes an Undo method and that there is an UndoEngineClass available.
Unfortunately the vs helpfile does not give examples of how to use / implement that class.
Could someone explain the usage of the UndoEngine class non-textbox controls and if it is advisable to use it or rather write my own (as I first intended to do - I also found some interesting articles about undo/redo classes) but why reinvent the wheel in case .net already provides a class for it.
thks
I need to retrieve only selected portion of a webpage (user open a webpage in web-browser control, then he/she would select some portion of a webpage, i just need only those selected portion/text) in vb.net in visual basic language. How to do ?
i am using microsoft visual studio 2008
Language: Visual Basic
FrameWork: vb.net 3.5
Perhaps here are some answers for you(first post attachment):
Manipulate/Change/Form Fill data in webpages using the Webbrowser control
In terms of IE's API, you can get the select text by getting the selection object via IHTMLDocument2::Selection the property, then create a range object via IHTMLSelectionObject::createRange. If the return range's type property is "Text", you can then query IHTMLTxtRange from it and get the selected text via IHTMLTxtRange::text.
It is unclear which webbrowser control you are referring to. There are 3 webbrowser controls in the .Net Framework, one in Windows Forms, one in WPF, and one in Silverlight. Anyway, you can call InvokeScript or use the unmanaged interface like csexwb's GetSelectedText, if one of the method is supported by your control library.
Next time mention which control library you are using when you ask the question. Merely mentioning the language you choose isn't enough to resolve the ambiguity in class names.
