View 5 RepliesI have a textbox "myTextbox" and a listbox "myList" which shows a list of strings e.g "AAA", "BBB", "CCCC".When the user clicks on an item from the listbox the text must be appended to the end of whatever is in myTextbox with a space preceeding it. e.g " AAA".The user must never be allowed to delete the added text.The user must be allowed to manually enter text in the textbox but it must always be in front of the added text. They must never be allowed to type over the added text or after the added text.I have been trying to get my head around this for a day now and cannot figure it out.

Its so embarrassing to ask all of them with inputbox while codes are working. I made forms for each tables which will be created.

Does anyone has an idea ?

I am concatenating a variable onto a path(string), i'm using a message box to display this for testing purposes, I can see that the variable is starting on a new line, which in turn when i try to open the file it doesn't recognize that the file exist...
Dim Path As String = "C:UsersstefanDesktopUni WorkYear 4ProjectsProject SelectionProjectProjectinDebug"
Shapetext = clickedShapes.Item(nextShape).Text.ToString.Substring(0, clickedShapes.Item(nextShape).Text.IndexOf(" "))
MsgBox(Path + Shapetext + ".txt")
This code works if I take out
" " + p.MIDDLE_NAME
Thus the remaining code looks like:
p.FIRST_NAME + " " + p.LAST_NAME
Maybe LINQ-to-Entities just doesn't support concatenating more than two strings at a time?

I need to :
Read data from a file. The file contains the location and file name of a file and the name to which I want to save as (about 27,000).

Where to find some samples of reading, parsing and concatenating data and running a program from within a script?
Is it possible to use 'Tab Stops' when you're concatenating (say) a Label text? I know it can be done for a PrintLine statement but I'm, trying without success, to put tabs after the colons in this code. ( "...... :" & vbTab ...)

Label1.Text += "Height margins:" & b.ToString & " Pixels" & vbCrLf
Label1.Text += "Top margin:" & c.ToString & " Pixels" & vbCrLf
Label1.Text += "Bottom margin:" & d.ToString & " Pixels" & vbCrLf
Poppa.
I'm concatenating data files, but the problem is that I'm seeing some extra bytes where the files are joined. The new file has extra bytes. I had thought this was maybe a problem with encoding.Here are the methods that I've tried to use to concatenate the files. The first example I'm getting extra 0xA0 0x00 bytes.
Dim inputfiles() As String = Directory.GetFiles(sourcedir, pattern)
Dim bufSize As Integer = 1024 * 64
Dim buf As Byte() = New Byte(bufSize) {}

I have this simple-minded query:
select a.str_number+' '+a.str_name+' '+a.str_suffix+' '+a.str_apt AS addr from mytable
This query works as long as none of the concatenated values are not NULL. If any is null, the address does not show.
I tried this:
select IsNULL(a.str_number+' '+a.str_name+' '+a.str_suffix+' '+a.str_apt AS addr,'') from table
What I would like to accomplish is to replace NULL with empty space if the value is null but I still get no values.
I've been trying to reuse my bosses vb.net buildpacket code which he has successful used for Serial programming eg. SerialPort1.Write(buildpacket(useraddress,252,"0006","0") for the function listed below.My challenge.Create equivalent functionality for Socket BeginSend() which requires a byte array.Whether modifying the vb.net below or getting a c# equivalent to work, it has been repeatedly recommended to scrap the string concatenation approach for which I have to use Encoding.BigEndianUnicode.GetBytes() and then getting rid of extra bytes with zero values.
I'm lacking in imaging something different which would work for socket programming directly and allow me to eliminate all the hassles that c# integer conversions into string value that can be encoded trouble free.I would need to call the equivalent of the following that would return a byte array rather than a string with the following arguments
1. Source address (0-255)
2. Destination address (0-255)
3. Function code ("0001" through "0100")

View 1 RepliesI am having an issue where I am using regex.Replace to replace part of a string. The basic idea is that I want to capture the beginning of the string then replace the end of the string with a value from code. For an example pretend I have a string that says "Test Number " followed by number and I want to increment that number. I capture the "Test Number " but when I try to concatenate that capture with the new number it treats the capture ($1) as a literal and replaces the entire string with $1[new number].
[code]...
This will output "We are on Test Number 2", as expected. how I can use a variable in the replacement string portion of the Regex.Replace when including a captured group?
