.net - String Not Printing As Expected
Mar 28, 2011
why the Output window does not print the "xxxxx" part of the string? Looks like I'm missing some basic understanding about something...?
I'm sending string messages over TcpClient, and when building the strings, I don't add any special characters on the sender side, and neither on the receiver side.
[URL]
EDIT:
I'm building my strings at the sender side like this:
Private Sub SendData(ByVal stringArray As String())
SendData(GetMessageString(stringArray))
End Sub
Public Function GetMessageString(ByVal array As String()) As String
[Code]....

I have the following value 48.81, it comes as a string from the database, I need to convert it to decimal, I'm using:
Dim Seconds As Decimal = Convert.ToDecimal((Coordinate.Substring(4, 5)), CultureInfo.InvariantCulture)
I'm receiving 4881D and I need 48,81
I thought CultureInfo.InvariantCulture was going to help me with that
EDIT:The coordinate value is 675900.244.I'm "spliting" it like this:
Dim Degress As Integer = Coordinate.Substring(0, 2),
Dim Minutes As Integer = Coordinate.Substring(2, 2),
Dim Seconds As Decimal = Convert.ToDecimal((Coordinate.Substring(4, 5)), CultureInfo.InvariantCulture),
[code]....
This is the value of the coordinate in the database?

i am having a bit of trouble getting a string to print a specific number of times. I am writing a do...loop or a For...next statement where it prints a string ("*") times the counter on the do...loop/for...next but can't quite get it to work.

I am writing an OPC Client in VB.NET (2008) and I am using an OPC wrapper from Graybox. I am having some problems with the data types. I have an Array of String that contains all of the OPC Items that I wish to read from the OPC Server. When I attempt to use the Array of String, Option Strict causes the following compile error message:Error 5 Option Strict On disallows narrowing from type 'System.Array' to type '1-dimensional array of String' in copying the value of 'ByRef' parameter 'ItemIDs' back to the matching argument. How do I pass the Item ID's (all strings) in an array?

I am using VB 2008 & Access Databases for creating WinForm Applications. Also i am using Crystal Reports for Report solution. my question is How do i created reports such a way that they can be printed in faster Ascii Format on any DotMatrix printer. The default true type fonts make printing very slower.
I tried to use "Draft 10 cpi" font which come to available me after i installed a correct driver for my Epson printer. which also helped me overcome this problem. however it wont be the scenario with all my clients i.e. they might have different printers having different Make with different drivers installed. i have tried to open such project on there PC but the printing wont come in Draft instead the fonts get expanded too much & the print wont come right.

I basically have an application that generates reports in a .html file, I use a .html file for the ease of making tables and formatting text.Now I would like to introduce a way of printing the reports from my program. Because I use a .html file, the formatting would not the correct if I was to print it directly from my application (as far as I know). For this reason, I would like to print it just like my web browser would have in order to keep the tabular data intact and the text formatting.

I'm creating an application which has an scheduler to print and it checks if there is a pending job on the print queue before it prints the next file. I use a timer which checks if there is any file to be printed on my database. Example, the timer ticks and selected 10 files to be printed, it should print the 10 files 1 at a time, if there's no print queue, that's the only time the next file should print. I think another timer is required which will keeps on checking if print queue is done. How will i do this?

When I print the output to a PDF file using PDFCreator, it stacks all of the letters onto each other rather than creating new lines at the places I've specified. I've also tried using vbNewLine instead of vbCrLf, but I haven't had any luck. I searched the web for this but couldn't find anything about it.

I want to fetch data from a database table modify it and update it without being dependent on the database provider and the database structure, because it will be part of a library.My first attempt was as follows:
'factory defined somewhere else as DbProviderFactory
'connection is a working DbConnection
Dim selectcmd As DbCommand = connection.CreateCommand()[code]....
it did not work. After further investigation I figured out that the Commands the CommandBuilder generated were useless, because it inserted ? instead of @param1 for all Parameters. It generated something like INSERT INTO tbl1 (field1, field2, field3) VALUES (?, ?, ?) for the InsertCommand.I would really like to use the CommandBuilder, because it is simple and I don't have something complicated like JOINS.

I have a query like so:
Dim clcexists = (From p In dbContext.Signatures _
Where p.StudentID = people_id _
And p.ContractType = "clc" _
Order By p.ID Descending _
Select p)
Later I check whether any rows exist in clcexists using IsNothing like so:
If IsNothing(clcexists) Then ' If no CLC is on file.
clcfirst = Date.Now.Subtract(year)
clcdate = clcfirst
[Code]....
But IsNothing() is not functioning like I expect. There is no row in the results table, but it is still acting as if there is and going to the Else clause.

(The Lines array is actually just the count of Paragraphs in the text, why they call it lines I don't know. )In order to do this, with word wrap, I need to know when I reach the end of a line. So in the Key_Down event I use some code to calculate the length of the current string and compare it to the width of the container. It turns out that the string is too short.

I am running Windows 7 pro and using Visual Basic 2010 express.I have written a small program to switch on a USB relay which is controled by a serial port.I have debuged the program and it appears to work correctly. I have published the program and if I start it from thr run menu / desktop shortcut / or through explorer it works as expected.
However I have tried to run it by the Task Scheduler and then it fails to run as expected. I have a small section of code that checks to see if the serial port is present if not I have used messagebox.show to ask for the relay to be pluged in. In every case other than when running through the Task Scheduler the messagebox works with the Task schedulerit doesn't show the messagebox and the program hangs I have included the code I have used.

The following code produces the compiler error "Expression expected" (Sub is underlined).
Dim lambda As Action(Of Integer) = Sub(x) Console.WriteLine(x)
Why does this not work?
Note: The corresponding C# code works:
Action<int> lambda = x => Console.WriteLine(x);

[URL]. I have a Multi-Line textbox with several accounts in it. They are in email@email.comassword format on separate lines. All the code is right, but it goes really weird and loops like 3 times before logging in. Eventually logging into the last account on the Textbox instead of the first. It should just login to the first account...Logout....Login to the second account...Logout and continue the process.
If you want to test it, just put a web browser and a textbox1 multiline box, a button and enter a few working hotmail accounts and you'll see.
Check line 17
Looks like a lot of code, but line 17 is the only bit that needs to be looked at. The rest is just junk/non-relevant to this problem. It separates the accounts perfectly and stuff, but just wont login in the right order.
