I need a simple implementation of a RichText control and assume there is one in .NET? Was going to use Stan's post displaying a .NET ListView(grid?) as a starting point but can't find it. Could someone give me a nudge in the right direction. The new .NET stuff is still a bit arcane to me and usually have trouble getting headed in the right direction. Thanks.

While it is possible create a form using WinBatch's CLR support, the big problem is that WinBatch has no mechanism for supporting delegates and no delegates means no event handling. Without events you would be hard pressed to respond to user interaction with in your control.

Here is the forum post that I think you are referring to: http://forum.winbatch.com/index.php?topic=200.msg709#msg709

Sorry I don't currently have a sample code using System.Windows.Forms in WinBatch. If I am able to track anything down I will post it here.

Here is a code sample of a very simple messageBox:

Code: Winbatch

;~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
; ObjectClrOption - Load assembly into the WinBatch process
;~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
ObjectClrOption("use","System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089")

;~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
; ObjectClrNew - Create a class implemented by a managed assembly. 
;~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
MB = ObjectClrNew('System.Windows.Forms.MessageBox')

;~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
; Display results
;~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 
MB.Show('Text', 'Caption') 
Exit

Events are not an issue. I have a situation where I need the user to be able to paste formatted text (often from a web page or MSWord) and then simply exit and I save the results. I have tried numerous options but have common situations where when I return it from the database for display there is nothing. I think it has something to do with odd characters in the text and have been looking for a way to paste that cleans it up a bit so it works. Seems to work if I paste to MSWord and save to RTF format and then open that document and paste it in. Have spent many hours trying many different things/controls over the years but no joy so far. Open to other suggestions.

Thanks.

Darn it -- I get "1299: dll: DLL not found" on that first ObjectClrOption('use' line.

I'm on Windows 7, winbatch 2014A.

Anyone know some other magic numbers I can try on that 'use' line?

I am also testing on Windows 7. It appears I have installed a newer .NET Framework.

On your system take a look at the following directory: C:\Windows\assembly\System.Windows.Forms

Now locate its subdirectory. What is its name? This will give you an idea of what values should be specified in your ObjectClrOption USE statement.

What is it named on your system?

td · « **Reply #10 on:** February 11, 2014, 03:04:59 pm »

Try changing the version from Version=4.0.0.0 to Version=3.0.0.0, Version=2.0.0.0, or Version=1.5.0.0. 3.0.0.0 should work on Windows 7.

Also note that as of dotNet 4.0 the GAC is located in %WINDIR%\Microsoft.NET\Assembly instead of %WINDIR%\Assembly. Older versions of dotNet are still in %WINDIR%\Assembly even if you have installed 4.0 or later. The down side is the new location does not have the nifty shell extension that allows you to easily view the version, language and pk info.

kdmoyers · « **Reply #11 on:** February 12, 2014, 05:24:11 am »

(I got it to work with 2.0.0.0 but it failed later with a bad parameter)
(I found and installed dotnet 4 and then the sample code worked as posted.)

This is a very cool sample, but tricky to make good use of.
Thanks for posting!!!

Works for me. Great Job Deana!

That being said. As the default form is re-sizeable, does .NET permit re-sizing the individual controls to fit with the resized outline. I say this realizing the limitations of using windows forms in terms of events etc...

They more or less beg the question - how to implement

In your RTF code, you can
Form1.AutoSize = _True

but then trying
button1.AutoSizeMode = Form1.AutoSizeMode.GrowAndShrink

will error.

Deana · « **Reply #15 on:** February 12, 2014, 01:09:54 pm »

It appears AutoSize Property and the GetAutoSizeMode/SetAutosize mode only relate to how the control resizes its self based on its content, not the size of the form. I haven't found a way to dynamically resize all the embedded controls.

I would expect the you would need someway to be notified the form has been resized. Currently Delegates and Event Callbacks are not supported in the WinBatch dotNet implementation. This limits the effectiveness of UI related classes.

If you must have dialog resizing, then your better off sticking with WIL Dialogs.

Understood. So forget the re-sizing. To avoid creating a Windows form that cannot be resized, you do something like set border = FixedWidth, and create your own form with the forms top, width (and possibly other sizing parameters).

Now, I am just meandering... if the windows form wants pixels, might there be a way to design a dialog in WB and parse that code into pixels so the resultant form looks like the dialog - or create a dialog with a reportview with a couple of buttons, and transfer the sizing to a Windows.Form grid.

Sounds crazy and after posting and re-reading I may have to agree.
