Re: TextEditor
First thing to notice is that the default font is sans serif.
Make it fixed width like Courier New.

If you resize to small your resize code generates an error
VB Code:
```
Private Sub Form_Resize()
    'Resize the txtDocument editing window to fit the form
    txtDocument.Width = frmMain.ScaleWidth - 4
    txtDocument.Height = frmMain.ScaleHeight - 4
End Sub
```
The -4 creates a negative Height and Width
I think I have a resize module somewhere.
I'll try and dig it out.

For some reason the horizontal scroll bar is not working on the text box.
If you hold down a key you cant tell whether it has wordwrapped or if it is a new word.

An insert HTML outline would be good too.

HTML Code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <HTML> <HEAD> <TITLE>HTML 4.01 Transitional</TITLE> <META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=UTF-8"> </HEAD> <BODY> </BODY> </HTML>

ConTEXT has a lot of useful features like this.
It might be worth downloading it and picking out the best bits.
One feature that is has is the autocomplete is based on external text files.
This is useful as the user can add/modify/extend it as he wishes.

Re: TextEditor

Here are 3 resize examples.
2 API and one manual.

The API examples have the advantage that they don't flicker.

All of them need tweaking as I didn't write any of it myself :afrog:

The upload is a 7z inside a zip.
I use 7zip for the greater compression ratios, but VBF doesn't support the extension.
Download ZipGenius http://downloads.zipgenius.it/ if you cant open 7z files.

7-Zip currently offers best compression ratio available http://www.7-zip.org/

Re: TextEditor

Cool, thank you. I'll take a look at the "resizers" later, I just reformatted so I'm involved in reloading my life at the moment.

Do you have any idea why the horizontal scrollbar isn't working? I think I've had this problem before and the fix was sending a message to the RichTextBox telling it to expand it's right margin.

Re: TextEditor

Aha! I had never seen the RightMargin property before, I had used the SendMessage API to set it.

I haven't yet tried out the control resizers yet, I'll hopefully get to that this evening.

Re: TextEditor

arg, I'm very sorry. Haven't gotten around to testing the code yet...school, work, and life in general seem to want a shot at my attention all at once.

Re: TextEditor

I know what you mean.
It doesn't help that my motherboard has died at home too :(
Perhaps we should have a list in the first/second post identifying what needs doing next, new/proposed features, problems etc
And maybe put a copy of the latest code there too?

It might make the project a bit more structured.

Re: TextEditor

Ouch, that isn't good. I'll update the 2nd post in the thread to hold that information. I may actually get around to testing the code today, but it's more likely to be done tomorow.

Re: TextEditor

Okay, I finally got to look at the code you posted. I think just adding an "On Error Resume Next" to the Form_Resize sub would be fine, unless you think there should be a minimum size.

Well worth a read

I'm not sure how far you have got with the Intellisense but there is an interesting demo in C# here

Re: TextEditor

wiz126 put a small intellisense demo on his server
http://www.scriptsorcodes.com/images..._Intellisense/

It needs enhancing, for instance I reckon you need to load the keywords from a file so that it is easy to update/add new words/languages

It also needs to use a popup and select with the keyboard instead of the mouse.
But the general idea is there.

Re: TextEditor

The main problem I forsee with the intellisense is how to load different languages...The common delimiter is ".", but PERL's is "->". There are many other differences between main languages and so the job right now is to create a system that will support a diverse language environment.

Re: TextEditor

What you could do is put the delimiter at the top of the language file.
You then put that into a variable that gets looked for in the code.

Or to start with you could just support languages that have a full stop as the delimiter.

Re: TextEditor
I was thinking about how the insert form object could be trimmed.
Each of the subs is the same apart from the line that looks like
VB Code:
```
ToAdd = "<input type=""textbox"">"
```
This could be made generic and read the info from a setup file (ini / xml ?)
Reading from a setup file means that you can extend the language without recompiling.

Similarly for the HTML object (form/image/hyperlink) I was wondering if it would make the code smaller by creating the forms through code at runtime instead of manually at design time.
Again the values could be read from a setup file making the program more easily extensible.

What do you reckon?

Re: TextEditor

DarkX_Greece created an interesting simple HTML Editor

Does syntax highlighting.

Re: TextEditor

I like the idea of dynamic menus and forms, but I'm not sure how feasible it is. I don't know how difficult it is to subclass a menu and then tell which item is clicked in it.

I'll add this to the list of possibilities.

Re: TextEditor

Its late and I cant be bothered to reread the entire thread :D
But I was looking at the KDE Advanced Text Editor and Code Folding is useful
http://en.wikipedia.org/wiki/Code_folding

I'm not sure how to go about implementing it though.....:(

Re: TextEditor

That would require a complete rewrite of the input engine, unfortunately.

Re: TextEditor

Is this project still continuing?
Can you post the latest code?
Preferably somewhere at the top of the thread.
After I have finished my exams in the next couple of weeks I should have time to contribute if you need any input.

Re: TextEditor

It is currently in limbo,, there haven't been any major changes - life has been a bit too hectic recently, but it will cool down after Christmas. (Sister gets married Dec. 17th, huge project at work, etc). Any help would be appreciated, especially in brainstorming, don't want to do anything that limits future development and additions to the supported languages.

Re: TextEditor

This is C# code using ICSharpCode.TextEditor.dll and WeifenLuo.WinFormsUI.Docking.dll. This may or may not help the project but I like to contribute if this is C#.

Edit: This code is based on SharpDevelop and the solution is SharpDevelop-based (I guess VS2003 can open this solution file; even 2006VS can open this I guess, but there are some things not properly set because of incompatibility).
