.Net Program With COM ActiveX Capabilities?
Jun 9, 2011
I created a program with a textbox on it and a button that does something with the text in the textbox.How do I make that program COM visible, load it and automate it from another project?My goal is to be able to automate the program using COM:
Dim myProj as object = createObject("myProgram")
myProj.setText("Hello World")
myProj.buttonClickEvent()
Similar to how you can load a new excel and automate via interop:
dim xl as object = createobject("excel.application")
Dim wb as object = xl.workbooks.add
Dim ws as object = wb.worksheets(1)
ws.cells(1,1) = "i love stackoverflow"
How do programs do this? I'm looking for the answer VB.Net specific.

I'd like to create a Windows form that allows a tablet user to enter a signature. I'd then like to capture that signature as a bitmap on the clipboard.
I've got some code using the InkPicture ActiveX control in MS Word Xp (2002) and it works marginally - I think the control is hobbled because of security issues.
Is there a .Net control to capture mouse/pen strokes ala InkPicture? I see some old WinXP Tablet stuff out there but the capability should be part of Vista+ which is my target platform.
Should I just be looking for a simple drawing form example that can scribble a signature then get the image on the clipboard for paste into a Word doc as a signature (the ultimate goal?)

I am in the main process using Activex EXE to create a sub-process, Activex EXE project inside a class module, class module which there are two instances of the event the equivalent of two threads, I defined the standard module module1.bas as public variable a, in two instances running at the same time, how the definition of public variables are not used, such as a private variable, each carrying out their respective variables of the same name! For example the implementation of a = a +1 statement, let the first instance of a run, a steady increase from 1; when executed when an instance of 2, a should be an instance of a value when the two began to increase, but also from two examples of 1,2 , ... began to increase.

I want to add DirectX capabilities to my project and I don't feel like messing around to learn WPF at the moment. How can I include DirectX into my project running VS2010 .NET 4.0. I know MS no longer supports managed code for DirectX but is there an API module or something I can get.

I'm working on a program that needs Speech Recognition and every website says to download the Microsoft Speech Recognition Engine. I can't find that, but I've downloaded all the SDKs. Are they the same? And it always says to add a speech recognition component to the form, but I can't find where that is in Visual Basic 2005. I'm using the Express Edition, but I don't think that matters.

I have been working with TWAIN driver for few days. I have learnt how to connect to the scanner or get the working scanners connected to the machine. I am having a problem now, eventhough i get connected to the scanner, I am not able to set the capabilities from my application. The scanner scans using the capabilities that are set on it but not from my application. I have looked at the sample code given with twain pro but even that doesnt set the capabilities of the scanner. For example if the scanner is set to 300 dpi and I set 200dpi from my application, the scanner scans with 300 dpi. It gives me an error saying that the value given is out of range.

I want to allow the user to write a little script (JScript, VB, whatever) with a function called by my application that returns an XmlDocument object (a string would be ok).I did some research, and it looks like the scripting engines are obsolete.
The best solution I could find is here: [URL]..But I was wondering if there is a better and more "official" way.

I've not got any issues with Cross threading but I hate the amount of work involved in sorting cross threading issues out.I thought today that my inherited Listview Control could have built in cross threading capabilities; it would decrease the amount of work on the form, and tidy things up.I've got this to work (EnsureVisible method), BUT I'm a little stuck when it comes to the Items.add below is my example control.

I want to create a server control that inherits System.Web.UI.WebControls.Button but gives it special capability, now what do i mean? i want my button to be a confiorm button that will work like so:
Renders to the page as a button of lets say cancel after the user clicks it i want to catch the click event (within the server control) and now after the click makeing the button not visible and makeing some kind of content placeholder (that will render from the server control) visible. that content place holder will have 2 buttons inside of it: yes and cancel. I want the programmer that adds this control to be able to register a function to the click event of the yes button. and the second cancel confirmation button should make the first button appear agian. (i know how to do this all in the client side but this time i need it all as server events)
My question is this: how do i catch the click event? i want it all to be handled inside the server control itself. so a programmer that adds this control wont have to worry about anything but just needs to register to the click event of the "yes" button.

I've seen quite a few questions about calling 32 bit ActiveX components on 64 bit platforms - as I understand it you can't create a 32 bit ActiveX component from a .NET application running in X64 (native) mode. This is OK and I think I understand it.But my question is more basic. Is there such a thing as a 64 bit ActiveX component? or is ActiveX always 32 bit, period?

I have a COM dll that has been developed under vb.net. The Control works just fine in IE 6 and IE 7, but when IE 8 tries to load the control, the browser crashes. I look at the event viewer and I get an error 1000 about iexplorer.exe and mshtml.dll. Do I have to build this com dll with IE 8 on my development machine? How can I track down what is wrong with the Control?

I am converting an application to Visual Basic .NET.I have an ActiveX DLL that I must use that contains a PublicNotCreatable class that contains these user defined types:
Public Type CSGSelectionItem
Primary As Long
Sub As Long
[code]....
I have come across a couple of problems with this. The most important problem is that VB.NET doesn't want to let me Redim the 'ItemList' of a variable with a type of CSGShapeSubSelection:
Dim cdtShapeSubSelection As CanvasSG.CSGShapeSubSelection
ReDim cdtShapeSubSelection.ItemList(lSelectionItemListCount - 1)
I get an error: 'Redim' statement requires an array.Also, it seems as though VB.NET has no knowledge of what CSGSelectionItem is. So, when I type:cdtShapeSubSelection.ItemList(0).I get no auto-complete suggestions of any value. I would have expected suggestions of "Primary", "Sub", and "OperationControlEffect", but instead I get "Equals", "GetHashCode" etc.

I have an activeX OCX which i used in my program in vb6 (it is a 3rd party component), it actually interfaces with a PLC to do some work. Now i am porting my VB6 app to vb.net (Console application), i tried to reference it and create an instance of the activeX. But i realised that my instance is always = nothing. Here is the code snippet of what am i doing and i have attached the activex ocx in a zip file. Will anyone test it if it will work in vb.net (Console apps only).

I created an ActiveX Control in ATL, which I can succesfully use in for instance Internet Explorer. When I want to put that object in a VB.NET (2003) app, I get some problems.
First I 'Import' the control, using Visual Studio, so there are COM Interop DLLs created. Then I insert the control in the toolbox and drag/drop on a form. The control is succesfully created.
However, when I run the VBApp, it crashes. The debugger tells me that it gets a 'Class Not Registered' error.
Same when I create a pushbutton and create the object manually:
Code:
Dim AxQuest3DCtrl As Object
AxQuest3DCtrl = CreateObject("MyControl.MyCtrl.1") //crashes here
If AxQuest3DCtrl Is Nothing Then

I have created a VB ActiveX Control. I embed the DLL using the following semantics. It appears to be working fine in my local machine. However, it does not in other's workstation. But I was not able to generate the LPK file using the LPK_tool.exe since the ActiveX control did not show up in the list.
<object id="printUtil" name="printUtil" classid="CLSID:440616e0-8d63-47b8-b16d-4fd281dc652b" >

I didnt know if this was the correct location to post this kind of question. My code is in C# however I am using the visualBasic. Interaction. CreateObject to connect to a OCX file. I notice that this works great for a while but if it continues to do its job for lets say a few days then I get and exception... "Can not create an ActiveX component." I am 100% sure that the ocx and dlls are registed correctly to the system.
