Capture signature and save it to external file

[JohnPapa]

I have developed a VB.net Forms application and would like to be able to capture a user's signature, store it in an external file as part of a pdf file and subsequently be able to view the pdf file.

There are several examples in C#, using inkCanvas, but was unable to find something in VB.

have you tried using a code converter like this one?

Telerik Code Converter by Progress is free online code converter from C# to VB and from VB to C#. No registration required. Check it out.

converter.telerik.com

converted the C# code on this site https://www.codeproject.com/articles/158339/signature-box-that-makes-the-signature-look-right

Converted code looks OK to me but not tested

I found this
Create InkCanvas in Visual Studio - WPF .NET Framework | Microsoft Docs

Do we need to use the .xaml file or can everything be handled with VB code?

 

[CJ_London]

sorry, no idea

I have used the converter. I just found it strange that no VB code example was available.

Will try the example you suggested.

Try this:

Signature Capture

This article includes two example apps intended mainly for use with a stylus or finger input on touch screens: signature capture & ink edit

.NET ready?

Sorry its VBA not .Net

Sorry its VBA not .Net

I have implemented it in VBA for the desktop application.
I am trying to implement the same functionality in the Cloud version which uses VB.net

I had a look. I could not find a beginning or an end to the article and the download is a .dll. Not very useful in its present form, to me at least.

Sorry I haven't done that so can't help.
I use code to email the collected signature to 'head office' instead

Are you using Fill and Sign by Adobe?

 

[isladogs]

No.
I save signatures as .GIF images for attachment to email
Doing that means no need to have an internet connection as such

The question is answered in the text itself:

You can access all WPF features from procedural code. Follow these steps to create a "Hello Ink World" application for WPF that doesn’t use any XAML at all.

Regarding the InkCanvas control, I recommend you investigate if and how a WPF component can be used in a WinForms application.
