I have a code where I search a text file for for example: "2320018200000", then it looks it up and finds a line like this[code]...
I want it to put that entire line in a label, but for some reason it skips the "3 1604001Sf" in the start. [code]...

View 6 RepliesMy program uses the serial port to receive characters as a string, then it should extract the integers from this string. This seems fairly simple, but so far has been a very tedious job.
My string is called txt. The problem is that there's no telling how many characters / integers txt will hold at any given moment. For instance, it may equal "4" or "4 5 6 7" or "P 0 1 2 3 4 5 6...255" - with spaces included. I need to reference every number within this string to use as data. I've tried the following:
dim c as new char
dim n as new integer
dim i = 1
[Code].....
I have a following value "1pm 2am" that I'm using a regular expression againts in SSIS to extract hours from in order to store separately. I've tried using both of the regular expressions below but both only yield the first number "1".
"(d+)"
"(*?d{1,2}*?)"
This should be fairly easy, yet I have no idea on how to approach this. Perhaps the split command . Anyway, what I need to do is split as string into two integers.
For example MyStringXS = "10, 20"
I need to end up with:
MyIntegerX = 10
MyIntegerY = 20
BUT!
These strings obviously change. So it could be MyStringXS = "120, 230" Or MyStringXS = "12340, 20342" And so on.
using Visual Web Dev 2008 Express and i am having an error when converting a set of integers to string. see code below. I cannot work out what it is that i am typing incorrectly. For ref, i return ten 0's as the result.

I have a bunch of 10 digit integers that I'm passing in a URL. Something like: "4294965286", "2292964213". They will always be positive and always be 10 digits. I'd like to compress those integers into the smallest possible form that can still be used in in a URL (aka letters and numbers are perfectly fine) and then uncompress them later. I've looked at using gzipstream but it creates larger strings, not shorter.

View 2 RepliesSo I had a smart idea to make a dictionary with all my variables so I could save them easily in chunks. This includes String, Boolean and Integers. When I was in Framework 3.5 I only had a few warnings about stuff that I didn't have coded in, but now in Framework 4 I am maxing out all my warnings with Implicit conversions. Personally I don't want to go to every number and put quotes around it put quotes around "True" because then it may change the method.

View 4 RepliesI have a class and method exposed to a client asp.net app. The class looks like
<DataContract()> _
Public Class Class1
Private v_string As String
Private v_integer As Integer
[code]....
The method is declared as
<OperationContract()> _
Function GetStuff(ByVal bar As Class1) As String
In the client code I create an instance of Class1 and set the values for v_string and v_integer, but using Wireshark to look at the xml being sent to the server only a value for v_string is being sent as part of Class1. I'm guessing this is because it considers the value of v_integer to be null/not set. Here is an example of the client code.

Basically I have and array of integers that vary in size. I need to compare each number to each other number and display which number is repeated. For example:
Dim ints() As Integer = {1,2,2,5,4,6}
The number that shows up more than once is 2.
How can I run through the array and compare each integer with the numbers in the array. I tried a for loop but it didn't return the value I was looking for.

I think this was executed before all the other tool boxes loading. So where should I put Form2.Show()?

Is there ANY possible way to do that (replace # with the number of the counter.) I doubt there is, but it never hurts to ask!
As a side note, where is a good place to post the jeopardy game that I am making in these forums, i tried both the code bank and gaming forums but they are dreadfully inactive.... since it is in VB.NET, i was wondering if i could post it here.
It is still in the making, but I would really like some feedback as i worked hard on it and got stuck for 6 hours on the save/load feature that was getting messed up cuz of a difference from A and a lol.
I got a quite a big sql statement and I get errors when dealing with dates and numeric values. All of this is in order to copy the data to a new table.so these variables I am trying to use for passing the data:
Dim orderdate As Date 'on my sql orderdate is datetime
Dim custntitle As integer 'on my sql is numeric(2,0)
Dim country As Integer ' on my sql is numeric(3,0)
for the date I get an out of range exception,and for these two integers (custNtitle, country) I get invalidCastExceptions when dealing with strings there's no problem but dates and numbers causes errors for me?

View 8 RepliesI guess that I'm not the first who ask this, but what is the easiest way to use threads in VB.NET? I mean, I need to download some string from a remote server and then to show that string in the GUI, so I have to use some callback function to call it in the main thread. I found different approaches for this, but all seems very difficult compared to Python where (with GTK) I used something like: gobject.idle_add(callback_function, parameters) and "callback_function" was executed in the main thread. How I do that in VB.NET?
View 1 RepliesI have a form with 12 text boxes. I'm trying to get the data from those text boxes to "save", and when that form is opened again have the data be inserted back. This form has different time slots so I need to be able to have it save and repopulate based on what time slot I am clicking on. I was going to have it read the data by splitting it with commas, then inserting them back into the correct fields but it's not working. I had it write the results to a text file and they get written correctly and inserted back, but the problem with that is it only reads that text file so every time slot I open up gets the same data.
Below is code I used to get the data when the Save button is clicked. [Code]. Problem is I get an error saying "Char values cannot be converted to Integers" on the first line, the (","c) part.
Look at the first section of code below:

This code is used to load a PDF in a PDF viewer. Because the PDFs are sometimes huge and there is no idea on how fast the machines are that will access the app, I have created a form to show that the program is busy thus the "ShareClass.LoadingIndicator" routine.
Here is the ShareClass.LoadingIndicator Routine:
Shared Sub LoadingIndicator()
Dim frm As New LoadingIndicator
frm.TransparencyKey = Color.Magenta
[CODE]...
The problem I have is that when the app runs and these subs fire, the LoadingIndicator form shows up but the ProgressBar1 and Label1 show as all black on the screen. I tried to make a screen shot of this but the screen shot showed nothing as if the form wasn't even there. How can I resolve this? What I would like to do is make the LoadingIndicator form be borderless so it appears as a label and progressbar laid ontop of the loading PDF reader as the PDF loads. If I take the transparency off it works fine.
