Unexpected Result Of RTF Line Ending Conversion
Jul 8, 2011
If txtLog is a RichTextBox control:
Dim text = "hi" & vbCrLf
Debug.WriteLine("t:" & text.Length) ' --> 4, as expected
txtLog.Text = text
Debug.WriteLine("tL:" & txtLog.TextLength) ' --> 3. muh?! :(
Having looked at the RTF spec, the end of a paragraph is notated as par, which is neither CR nor LF. This makes sense since RTF is markup language; like in HTML, line endings have little meaning on their own.
So presumably, on writing into the RichTextBox, my line ending is being encoded into par. And then, on extraction, the par is being translated back to a real line ending for use.
It turns out that this line ending is vbLf.
Why, since Microsoft near-consistently employ CRLF for line endings, would RichTextBox translate par to vbLf instead of vbCrLf?

I have a small project which I want to add a different text at the beginning and the ending of each line in a multiline text box.I've tried this, But It only let me to add it at the beginning ( because I don't know the length of each line And also I have to write a code for each line which is very hard because the text box may contains 200 lines Dim lines() As String = TextBox1.Lines lines(0) = lines(0).Insert(0, "Hello World")TextBox1.Lines = lines I want for all lines without having to repeat it again for each line

I wrote a program that writes to a new created file a line of text. Anytime I try to open the new created file, I see a dialog box titled "Inconsistent Line Ending". I do understand why I receive this message. I wrote this program in VB.NET.

I am currently writing a code that prompts a user if they want to convert F to C or C to F, two functions with the calculations. My problem is my loop, it exits one time through and doesn't prompt again. And also doesn't display the final result.

I have this snippet, it's in Java:
final InetAddress address = InetAddress.getLocalHost();
final NetworkInterface ni = NetworkInterface.getByInetAddress(address);
key = new String(ni.getHardwareAddress());
Example of key output: ▲╔UiÎ
What is the equivalent in VB.Net? I understand the first line gets Local Host, what about the rest?

I am currently having a headache on how to solve this problem that i am facing. here is the situation: I have a combobox and a list box on the main form. The combobox will get the data from the ms access database. In the database, i have the details of a person's IC, Name and DOB say for eg on one entry I have D215311523C,SHAWN,13/04/1987 So now, my combobox on form load will show the list of dates in the database to allow the user to search base on the date itself by clicking on the selected date. So when the user clicks on the particular date say 13/04/1987, people in the database whose birthday is 13/04/1987 will be shown on the listbox.Meaning to say if i have 3 entries whose dates are the same 13/04/1987, 3 entries will appear. If there is only two entry, then two results will be shown. But now, when i do a single click on the date, one result will be shown. That is correct. But the problem is when i click on the same date again, three of the same results will be shown on the list box. that is it will display : 13/04/1987 13/04/1987 13/04/1987 which is not the case. Then it will show more duplicates of the same results if i click more times on the same date which should not be the case.
Dim n As Integer
Dim numbers() As Integer
Dim StartFrom As Integer
Dim EndAt As Integer

I am encountering the following issue So i have a device that sends stuff at the serial port, i then parse it and put it into an array of bytes like that:
Dim HCI_Command_Rcvd_Byte() As Byte All good till here What i wanna do is make an array and put this result every time the serial port gives me a new result, for example:
[Code]...
Basically what i wanna do is let the port parse the messages, fill in the array with the result at an empty spot in this array and then i will have a separate thread that will look in into this array in each non empty space and after it looks into the non empty space it will use or discard the info and also mark this space as empty (after it checked)

I just read about DataSet in VB.NET, it uses disconnected concept. My question is: if my apps has "List All" button that query data from 1 table in the database, and that table has "very very very" many rows, so my DataSet will be filled with those data and eat up memory. Can I limit the data that being put to the DataSet from that query? But I want to be able to retrieve the next data from the same query if the user want to see it?
For example:
I have 1000 rows in my database, and i query all of them. But I just want 200 rows being inserted to my DataSet, but if the user want to see rows number 201 and so on, I want to be able to retrieve the next 200 rows, and so on. So it just like cutting those data into a group of 200 rows. Can I do this with the concept of "disconnected" of the DataSet?

I'm writing a class library and I need to be able to shut down the main code in certain cases.
I know I could raise an event and listen for it in the form called by application.run but I would like to find a way around it.I wouldn't be opposed to try to throw an exception that if unhandled would close the application... but would prefer to come up with a more elegant soln.

I converted this app from VB6. I have 2 forms. Form1 instantiates Form2 via a Menu Item.I am having trouble getting Form2 to end when clicking close (X). If Form2 is 'idle' it closes fine; but if I am in a loop processing anything all the events fire, but it continues processing in Form2. I've tried messing with Dispose, Close, Application.Exit, Application.ExitThread. My last attempt was creating my own event to fire back to Form1 and dispose Form2 -- and it hits it but Form2 is still running. What is the deal? BTW if I use just Show vs ShowDialog -- Form2 just blinks and disappears.[code]

vb.net threadsEnded = 0 For j As Integer = 0 To numThreads - 1

Some times the application doesn't finish and if i pause the application i see that the threadEnded var doesn't have the correct value, seems like some thread doesn't update the value of the var.

I'm creating a program in VB.net that does the following:At a high level I receive a file in email, put the attachment in a monitored folder, import the text file to excel, format the excel, and then email the excel file to a list of recipients.
Here is my plan:
Completed: Outlook VBA to monitor all incoming email for specific message. Once message is received drop attached .txt file in a specific network folder.
Completed: (VB.net) Monitor folder, when text file is added begin processing
Not Complete: (VB.net) Import text file to Excel
Not Complete: (VB.net) Format Excel Text file.(add in a row of data,format column headers with color/size, add some blank columns, add data validation to some of the blank columns that allow drop down selections)
Completed: (VB.net) Save file.
Completed: (VB.net) Send file to list of recipients.
Obviously the items above that are not complete are the bulk of the work, but I wanted to get some advice on what some of you think would be the best way to approach something like this. The import and formatting of the file are causing me some problems because I just can't decide what would be the most efficient way to do this.
The way stated above. Import to excel -> format Having a template excel that contains all of the formatting already done for me and attempting to transition the data to this document (no clue if/how I can do this). Is it even feasible? Have the template already created and then import the text file to a new excel file, then transition that data to the excel template?
Something I thought about, in terms of formatting the document, was to record a macro of me doing all of the formatting that I'm going to need and then attempt to convert that macro into my vb.net code, but I'm not sure if that will work. I will need to verify that the text file comes in the EXACT format every time correct?
