Re: Get the last line from a constantly updating textbox Jarno Burger28-May-09 4:10 Jarno Burger 28-May-09 4:10  what did for my debugger , put every given string in a array with a fixed length. when there was a new string , i fisrt moved every string one position in the array , meaning that the first one would be dumped. FIFO. a array with strings was a lot easier to edit/view. you could also use a queue , but i love to build stuff myself , loving hobby code Jarno Burger Video Jockey Re: Get the last line from a constantly updating textbox [modified] The Mighty Atom28-May-09 6:36 The Mighty Atom 28-May-09 6:36  Hmmm... this is tough. I tried a listbox to display the output, and it works fine, even better than a textbox. But what really annoys me is that a listbox does not allow you to colorize specific items (fore and backcolor). It also flickers like crazy. So was thinking, are there custom listbox controls out there with the exact same functionalities is the stock listbox, only with the added ability to colorize the backcolor and/or forecolor of specific listbox items? I google like crazy today but found squat. http://www.themightyatom.nl modified on Thursday, May 28, 2009 12:51 PM Re: Get the last line from a constantly updating textbox DidiKunz29-May-09 4:22 DidiKunz 29-May-09 4:22  I don't think there are such list boxes. I would stay with the textbox or use Scintilla.NET http://www.codeplex.com/ScintillaNET[^] it has syntax colloring built in. To get the last line, search backwards to the first cr/lf and you got your line. Good luck: Didi Re: Get the last line from a constantly updating textbox The Mighty Atom1-Jun-09 3:22 The Mighty Atom 1-Jun-09 3:22  Yeah i think so, i already found a custom listbox control that supports item colors, but it flickers like crazy when items are added in a short timespan. Ill try that ScintillaNET thingy. If i understand correctly, this is a pack with new/updated controls with new features? http://www.themightyatom.nl Re: Get the last line from a constantly updating textbox DidiKunz1-Jun-09 8:01 DidiKunz 1-Jun-09 8:01  You could use BeginUpdate and EndUpdate on your control before and after the adding of items (that works on most controls). Yes Scintilla.NET is a pack with controls in it... Regards: Didi Re: Get the last line from a constantly updating textbox The Mighty Atom1-Jun-09 8:20 The Mighty Atom 1-Jun-09 8:20  I tried the beginupdate and endupdate, but i want the user to actually see the process. As for Scintilla.NET, it only adds four unkown controls to the toolbox. I don't know how i could use that with my textbox. Plus, it makes my Visual Studio crash. :/ http://www.themightyatom.nl Re: Get the last line from a constantly updating textbox DidiKunz1-Jun-09 9:54 DidiKunz 1-Jun-09 9:54  you don't use it with your textbox, but instead of. Find documentation on Scintilla Documentation[^] Scintilla.Net is a wraper of Scintilla, a c++ rich text control with sintax highliting etc. What exactly do you do, just before your VS crashes? Re: Get the last line from a constantly updating textbox The Mighty Atom1-Jun-09 11:02 The Mighty Atom 1-Jun-09 11:02  Nevermind, im not going to use it, too complicated for me. Ill just stick to a richtextbox. If i just could find a way to get the last line of that constantly updating textbox, i may just get it to work. Syntax highlighting using regex isn't the problem, i know how to do it. http://www.themightyatom.nl Re: Get the last line from a constantly updating textbox DidiKunz1-Jun-09 20:50 DidiKunz 1-Jun-09 20:50  To get the last line, search backwards to the first cr/lf and you got your line.

Use the image property and select the file you want to use in the import box. Make sure the image you are trying to use is a supported format (which are listed int he Files of type combo). Cheers!

Or just heap variables are enough to be released? dim d as integer=0 Dim f As DataGridView=nothing try d = 10 f=new datagridview catch(byval ex as exception) finally d=nothing f=nothig end try Re: variable memory to release for heap or stack Henry Minute26-May-09 2:44 Henry Minute 26-May-09 2:44  Both of the members will be released and disposed when their references go out of scope. However from the code that you have shown there would be no harm in doing as you have done. Henry Minute Do not read medical books!

Re: variable memory to release for heap or stack Henry Minute26-May-09 3:42 Henry Minute 26-May-09 3:42  It depends on what the objects are. For example, it is recommended that Graphics instances, Pens, Brushes etc. are disposed as soon as they are no longer needed, becuase you cannot know how long it will take for the Garbage Collector to do its work. In addition any unmanaged objects should be disposed in this way. It does no harm to manually dispose objects, it is just that it is not always necessary. Henry Minute Do not read medical books!

But can u tell me any link that tell about the managed object and unmanaged objects. Re: variable memory to release for heap or stack Henry Minute26-May-09 4:46 Henry Minute 26-May-09 4:46  Try this[^] for some info about unmanaged objects (resources). For information about both, try googling managed v unmanaged objects or managed and unmanaged objects. There are so many hits that it is difficult to pick one for you. Have a look for yourself.
