I used the unicode character manipultation features in my code under VB.NET 2003. Will the code still work on Unicode characters that have been added to the Unicode standard since 2003? I am aware that there have been some characters added to the Unicode standard for Persian text since 2004.

View 4 RepliesI am working on a sub that essentially needs to open a text file, and replace all instances of a certain character with a unicode character. I'm trying to do this by reading the original text file byte by byte, converting it to a character, and then either adding that character to a memory stream or writing the unicode character to the memory stream. Then I'm saving the memory stream to the original file.

In my VB.NET application I compare words that are recorded using IPA, many of which have many diacritic marks. In one of the comparisons, I compare the words character by character. But when I iterate over the characters, the diacritic marks come out as separate characters (as I would expect since this is unicode)However, a u character is different than a u plus an accent for the purposes of this program and needs to be distinguished.

View 8 RepliesI want to insert a special character into a RichTextBox. The character is in a Medieval Latin font (Andron) which is installed on my machine.
When I open MS Word and select Andron as the font, then go to Insert Symbol, then scroll down till I find the symbol I want, I see that its Unicode value is A752, selecting it inserts it into Word OK.
Now, back to my VB2005 project: I have a RichTextBox on my form, and the Font is set to Andron. I have two buttons on the form. Behind the first button I have this simple
RichTextBox1.Text = RichTextBox1.Text.Insert(RichTextBox1.SelectionSta rt, "a")
Clicking this button simply inserts the letter 'a' at the insertion point, fine.
Behind the second button I have this
RichTextBox1.Text = RichTextBox1.Text.Insert(RichTextBox1.SelectionSta rt, ChrW(&HA752))
However, on clicking this button I get the ubiquitous square symbol, as if it cannot find that character, which is odd (to me) as the correct font is selected for the RTB, and that code is the correct code for the symbol I want.
Edit to add: I can now see that all characters up to Ascii (Decimal) 255 (which equates to Unicode 00FF) all display OK, but any value over that does not.

View 2 RepliesI am thinking of giving mono develop a try. I have some questions. Visual Studio 2008 Professional has options for creating controls and services. This is not available in Visual Basic 2008 Express. This relationship between the different editions, is there something limiting like this with mono develop? I figure since it's open source, everything is implemented like Visual Studio 2008 Pro.
Another question. Does anyone have experience with mono. Is it a production level serious environment for commercial work? Is there something I should know about it?
Any mono developer that has anything good or bad to say, please drop a post in here. I would like to get as much info as possible from vbforums. This has always been the best help site for me using Visual Basic Express.
The most important thing, to reiterate is if I can make Windows Services with Mono Develop and if it supports full threading features that are limited or not available in express.
As a last question, what is the story on managed directx for mono. On Linux, there is no such thing, so would you plan an opengl library to start with? or does that work out in a different way?

For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.

Some libraries are used by multiple apps, so the DirectoryRef would have to be pointing to multiple directories, and multiple DirectoryRefs (with different ids) would have to be pointing to the same directory (found directory alias trick), both of which seem impossible.I get the distinct impression I'm going about it the wrong way, or that I'm missing some deeper insight.

I even have it set up so I can filter through the DataGridView by sorting though a specific company in the database. However, now I want to link specific cells from the DataGridView to other VB features such as a text box and check box. I am a bit lost as to the coding. In the DataGridView, there are numerous columns that contain a check box and I need them to correlate to actual check boxes I have in the form. I can do it through binding the check box on the form to the data source and it works but if I run a filter or sort through the company, the check boxes from the DataGridView no longer carry over to the actual check box on the page.

I actually found a fairly good pong tutorial on this site which I've linked to at the bottom of this post. I used the code as my base and I'm starting to implement my own new features. I'm currently working on making the ball move faster after each hit of the paddle, but I can't get it working! I thought it would be as simple as adding 1 to the 'speed' variable during the test to see if the ball has hit the paddle. Doesn't work! I also tried various other methods, including adding an extra timer to the form and having the speed increase a certain number every tick on the timer. Didn't work! Is there some special way that I need to reference that variable in order to manipulate it? Code below.
