First of all my appologies for the late anwser. I have been away for a couple of weeks.

1. I have an UNDO menu item. It seems that multiple undos and redos are built in the Brainchild control. What code would I write to perform an undo operation when I click the UNDO menu item (or REDO for that matter)?
I can use the SendMessageLong win32 API Function but I need the handler (HWND property) for the control. Also, some controls have the UNDO and REDO methods exposed which can then be called directly in the program. I looked ath the cpp code for the demo [I am not a cpp progrogrammer ] but sort of
Calling Undo, Redo and quite a few other things can be accomplished through the ExecuteCommand() method of the OCX just pass it the ID of the command you want to execute. Look at the "brainchild_defs.h" file in the OCX sources to find the possible command codes. All defines starting with CID_ are valid for the ExecuteCommand() method. For Undo you would call:
ocxInstance.ExecuteMethod( 100 )

2. It will be great to have some more properties built into Brainchild that generally come standard with RichTextBox control and are very useful. They are:
Locked - true or false : If locked then you cannot perform edit in the control
BackColor - sets the backcolor of the control
Locked does not exist but you can set the control to readonly by setting the Readonly property. To change the background color of the control you can use the SetColor method. Use 1 (BCC_BACKGROUND in brainchild_defs.h) as the first parameter, the second parameter must be thr RGB value of the color to set.

3. I did not find the _change event but I think _cursorposition method does that. Right?
The controls fires several events. There is the OnCaretPosition event which get's fired when the caret (cursor) position changes. There is the OnStatusUpdate event which fires if the internal status of several flags change (see NMSTATUSUPDATE structure in brainchild_defs.h). Finally there is the OnFilenameChanged event which fires, like the name implies, when the filename has changed.

That line from the documentation is left over from the time brainchild still was distributed as an install package. This install package automatically installed the CPL into the system32 directory. If you want to be able to configure brainchild using the control panel you can copy the CPL and DLL in the System32 directory.
If you simply want to use the control panel applet from you VB application a simple call to the SettingsDialog() method of the OCX should suffice.
Is there any way to specify where the Brainchild.CPL file is located other than forcing it to be in the System32 directory?
It would be nice if the SettingDialog() method could look in the application path first, then maybe System32, that way a program that uses Brainchild doesn't have to add an item to the Windows Contro Panel.
Thanks,
Chris

Brainchild uses the LoadLibrary API to open the cpl so loading it from the application path should not be a problem. From the MSDN docs:
1) The directory from which the application loaded.
2) The current directory.
3) The system directory. Use the GetSystemDirectory function to get the path of this directory.
4) The 16-bit system directory. There is no function that obtains the path of this directory, but it is searched.
Windows Me/98/95: This directory does not exist.
5) The Windows directory. Use the GetWindowsDirectory function to get the path of this directory.
6) The directories that are listed in the PATH environment variable.

Jan

The links in the article seem to work just fine. They re-direct to the classlib article where you can download the necessary files. What are the problems you are having?

Hello
Well, i found some bugs in brainchild, hope you can fix them 
1) Problem with URL's, when erassing a url (Backspace) the underline is still there, and gets erased after some moments.
2) Problem with positioning the caret, when selecting a line from the left side, the caret will change it's position to go in the next line.
3) Problems when exiting BCDemo, seems on some cases when i start editing the code, and tries to exit, it will not, so tasmanager comes in handy.
4) Problem with the tabs, when openeing more than one tab, the code for each tab does not change only the first code for the first tab gets shown in all tabs.
5) When double clicking on the code editor, on words, it chooses all the word, disregarding any symbols joined with it.
6) Caret keeps flickering when hightling code from the left side and keep highling code, either going upwards or downwards.
Not critical bugs, but some may affect the effeciency of it, hope i have helped , and keep up the good work Jan

This is not a bug. The parser will determine wether it is a hyperlink or not by the prefix of the hyperlink. For example when you type http://www.codeproject.com and you start deleting characters the parser still thinks it is a hyperlink until you remove any character from the "http:" part of the hyperlink.

This is normal behaviour. The caret will position itself at the end of the selection. Since clicking in the selection margin selects to whole line including cr/lf the caret is moved to the start of the next line. You will notice that Visual Studio does it the same way.

This problem is known to me and is a bug in ClassLib, the C++ library which is used to write the BCDemo demonstration program. This is not a problem in brainchild.
asdf500 wrote:

I do not understand exactly what you mean here. Do you mean the title of the first tab get's copied on the other tabs?
asdf500 wrote:
5) When double clicking on the code editor, on words, it chooses all the word, disregarding any symbols joined with it.
Selecting a word by means of double clicking it will select the word up until the first white space or delimiter character. This means that double clicking on the wordt pMsg in a text pMsg->wParam will only select the pMsg part. This is normal behaviour.

I'll see what I can do about this.

Thanks Jan, for you speedy reply, well, not all bugs, but i did not know another word for them, language problem maybe, anyway, i think you misunderstood some point more specificly number 5, i meant this:
X = y[Index] double clicking on Index, will highlight [] aswell, this is what i meant, about problem number 4, is that when i choose a new tab - Untitled -, then try to open another tab from any existing file, tab names will remain the same and code will not change when changing tabs, thus only 1 code can be viewed.
About problem number 2, i still think it should not reposition itself to the next line, i have not seen VS do that, maybe you use another version than mine, and i come to a point where i see 2 highlighted lines, i don't really think this is normal.
Plus, when i mentioned there is a problem in BCDemo, i did not say it's in brainchild, but there is only 1 place to post such problem, which is the brainchild page.
Hope this clears it up for you, thanks in advance.

What parser (language) file is used? I cannot reproduce this behaviour over here. Does this also happen when you Ctrl+Click the word? Does the parser file have the square brackets in it's delimiters configuration?

Not exactly sure what this problem is but it is probably related to the problem where BCDemo can't be closed anymore. This has a priority on my TODO list.

I have seen this behaviour in VC 6, VS .NET 2002 and VS .NET 2003. Not sure about VS 2005 though... Still need to install beta 2.

When you click inside the selection/line-number margin to select a line and you do not drag the mouse then no, it should not select more than a single line. If however you keep the mousebutton down and you move the mouse up or down inside the margin more lines will be selected.

Yeap, that was it Jan, well, thanks much for your effort in hearing my reports , in the end i have only suggestions about brainchild, also, Code Folding/UnFolding is nice to have, intellisense and a browser feature where you can travel through code by function listing, anyway, that was really a very good job you have done in here, please keep up the goof work.
Best Regards

Some of you were having problems with the error "The application failed to initialize properly (0xc0000142).". This was due to the fact that the dll source code zip file did not contain the default settings files necessary to get brainchild up and running properly using the instructions in the article.
The dll source code zip file has been updated and now contains the correct files.

I am still getting the error after downloaded and recompiled all the files today. Starting BCDemo from Brainchild_Bin gives the same error.
Any suggestions? Thanks.

Never mind. Somehow the program is looking for a folder under Settings with the same name as user ID, not "Defaults".

Actually the DLL creates the user directory and copies the contents of the Defaults directory in there the first time somebody uses a program using Brainchild, at least this is how it is supposed to work. If you had to create the user directory manually something is wrong.

The DLL did create the user directory. However, it did not put anything there and I have to copy the Defaults manually to make it work.

Hi
I've done you instructions to get it working, but I just get: "The application failed to initialize properly (0xc0000142). Click on OK to terminate the application."
What have I done wrong?
Cheers

This weekend the article was updated with a new dll source zip which has the default settings files in it. It is possible that you downloaded before this and were unable to follow step 8 from the instructions. If so please download the dll source zip and try again.

I think they mean the BCDemo.exe in the Brainchild Compipled Binaries download. At least that's where I am getting the error.
|

No, it is due to the fact the default settings files were missing from the dll source code zip. This error is common when the registry key is present but the default settings files are not. The binaries in the article work fine as long as the default settings files are present.

OK

everytime I click "settings"...

This has probably to do with the fact that you cannot do step 8 from the procedure described in the article. The dll source zip file does not contain the default settings files. I will update the article as soon as possible.

I couldn't make the demo run:
Whenever I create the registry key, BCDemo crashes.
Without the key, BCDemo runs fine but is not configurable (of course!).
---------------------------
BCDemo.exe - Application Error
---------------------------
The application failed to initialize properly (0xc0000142). Click on OK to terminate the application.
---------------------------
OK
---------------------------
The setup description is somewhat strange: no zip contains a folder "Defaults" so I couldn't complete step 8 of the installation instruction.
What I could do:
-Get binary installation
-Perform steps 7,9,10,11 (1-6 should be unnecessary for the binary download?!)
How can I proceed?

Actually the BCDemo does not crash. It simply does not run because the brainchild.dll does not load properly. Much to my suprise I have seen that the source code zip file (Brainchild_dll.zip) is incomplete. It does not include the default settings files. If you give me you email address (Simply use the EMail link below) I will send you the files ASAP. When you have the files you can setup as follows:
1) Create a directory C:\Brainchild
2) Copy the binaries in this directory
3) Create a directory C:\Brainchild\Settings
4) Create a directory C:\Brainchild\Settings\Defaults
5) Copy the contents of the zip I will Email you into this directory
6) Create the registry key HKEY_CURRENT_MACHINE\Software\BCDLL\CurrentVersion
7) Create a string value called Settings in this key and set it's value to C:\Brainchild\Settings
Ofcourse you can replace the "C:\Brainchild" directory mentioned above with any directory you like.
I will update the article soon to include a complete source zip file. My apologies for the time lost trying to figure this out.
