I'm converting a user generated list box to an array and then generating a user defined number of random strings and placing it in a textbox.The code I have works fine as it will generate the number of random strings the user wants, except sometimes a line is blank at the top of the list but is counted as a string.

converting the number of frames (in a video) to a number/time format. For instance, say a video has 110,212 frames at 23.976 fps, it works out to 01:16:36 (hh:mm:ss) with 18 frames remaining. I would like to format the result in a Textbox like the following:
[Code]...
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub
End Class
I haven't got the code, however I got the physical part of the program done with a label called Numeric Number and another called Roman Numeral, with text boxs next to each label. I also have a button called "convert" so when you enter a numeric number in, it'll convert it to a roman numeral. I need it to only convert from 1 to 10, but not accept a number less than 1 or more than 10.
I have a SQL function that I am calling in my VB.Net code within a display function. The SQL function will format my account data to include the following results form a Table. The table data: "001000011121" (this is the type of structure the data has before formatted)
So the data table data and vb Properties would be called Myaccount, HerAccount, ThisAccount. Once the data is pulled and then formatted in the VB.net code it will result into a GridDisplay as as: "001.00.001.1121"
The way I have my Public Function in my code is:
Public Funcion GetDisplay(_
ByVal dbBass as DataProvider_
,ByVal pps AS TMGDatarequestParms_
,By filter As IFilter_
) As Ilist
Dim strobe As String = CType(parms.OptionalParameters, DataProvider).Database
Dim sql As BiGSqlBuilder(TABLE)
sql.Select = String.Format("ID, [{0}].dbo.GLForamtAcct(Myaccount) AS [Myaccount], [{0}].dbo.GLFormatAccount(HerAccount) AS [HerAccount], [{0}].dbo.GLFormatAccount(ThisAccount) AS [ThisAccount]", strobe)
I left out some of the return code since not necessary. The only thing I'm concerned is how to format the SQL within the VB.net Code above.
how do you filter/search a numeric number from your form feilds in vb.net. i have filtered a feild with textbox containing names(first name) but this time i would like to search/find what is containing in a numeric textfiled which is phone number textfield.A phone number is numeric and it might contain both characters and numbers. for example, one can write +44 7961400000. In textfield for fname, i have the following:
Me.EmployeesBindingSource.Filter = ("Fname Like'%" & TextBox3.Text & "%'")

I am using VB .net 2010 express from microsoft. I have a numeric up down box to display a variable that the user can choose a number for.

View 2 RepliesI have been working on recoding a VB6 client/server application of mine and have run into a bit of an issue with storing the players location on the tile map which means I will need to rework the way I am storing the user connections. In my VB6 application I would store the user's numeric index/socket number/whatever you'd like to call it as the Key, however, in VB 2008 I can't seem to find where, or if, the numeric index is stored. If this isn't possible then does anyone have an example of how they store user connections using some numeric index as the key of a hashtable?

I am trying to read the pc system information so that I can retrieve the time and date format.
My code below:
Dim Info As System.Globalization.DateTimeFormatInfo
Info = System.Globalization.CultureInfo.CurrentUICulture.DateTimeFormat
Debug.WriteLine(Info.LongDatePattern)
Retruns in debug: "dddd, MMMM dd, yyyy"
So I have 2 questions;
1) Why is there, a dd after the MMMM.
2) My company has small franchise branch offices round the world - France, USA, etc. What I am trying to do is get the date format so I can decide what country I am in - then when I print out the date on my order labels I can change the date format to suit Americans or Europeans etc.
I'm realy green when it comes to programming but I like to think I am learning quickly. However, I cant figure out how to generate a number of random numbers baised on the vailu of a numeric slider. So for example I am generating a number between 1-12 where each point of value for the slider would generate an indiigual number that can all be added to a final total. I would also like to be able to back the slider down to a previous number and have the same total I had last time I was at position x. This is what i have so far:
