I have a textbox where I can enter a number. If the number exists in my sql database then it would change the label accordingly.

Conversion Failed When Converting The Varchar Value When Calling Stored Procedure?

Jun 9, 2011

I am developing a Windows application for restoring specific databases from our Production platform to "field" tablets by using backups that are taken daily to disk. To preclude "orphaned users" on the tablets, I want to extract the "user name", "password" (hashed) and "sid".I am calling the MS Stored Procedure "revlogin" that produces screen text to copy and paste into a query to recreate those users on another SQL server instance.

IF (@denylogin = 1)
BEGIN -- login is denied access
SET @tmpstr = @tmpstr + '; DENY CONNECT SQL TO ' + QUOTENAME( @name )

Converting A Database Field (long Varchar) With No Length To String?

Jun 26, 2009

I'm pulling records from a db table (sybase) where I have run into a problem with a long varchar field. Using the OLEdb class I convert the field into a string variable which works fine in most cases, but there are problem with a few records. Examining the field in the database it shows that the value is not null, but the length of the field is 0.(SELECT field, length(field) FROM table). When I try to convert this into a string the result is rubbish.strContent = objReader.Item(i). I can't figure out what's the problem here, so I have avoided the issue by doing a table update before I start the process of getting data (I set the field value to null if field.length = 0

VS 2005 Converting Between Numeric Bases?

Apr 6, 2010

I'm having an issue with my base conversion program. It seems to have a problem converting from base36 to base10 properly. After debugging all night, I've found that it's one certain function that's not working properly. The function seems to convert every last test number correctly, until I start getting into 11-digit numbers in base36. I have the max digits allowable for base36 set to 12 (so as not to exceed the base10 18-quintillion or so that an unsigned long can hold). I'm starting to think the issue is with VB and not with my code.The function as I've written it is below (DIGITS is a global const string ="0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ", and itr is a global integer used throughout the code for iteration):

'-----------------
Public Function FromBase10(ByVal iValue As ULong, ByVal cBase As ULong) As String
Dim remaining As ULong = iValue

Converting Numeric Number To Roman Numeral?

Dec 7, 2009

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.

Page Calculator - Converting Input To Numeric Variables

May 16, 2009

Description of Program/Events. I would like to come up with a number generator that takes the Total number (for this example I'll say 20), divides it by 2, and does alternating additions so the end result will generate a list like this:
1, 11, 2, 12, 3, 13, 4, 14, 5, 15, 6, 16, 7, 17, 8, 18, 9, 19, 10, 20.

I can understand the arithmetic, just can't work out how to express this in code. The end result would be save in a .Txt file (I have added a SaveFileDialog1 control, but figure I need to get the result before I work on the export).
Dim StartValue As Integer
Dim EndValue As Integer
Dim TotalValue As Integer
' Convert input to numeric variables.
StartValue = Val(StartNumTextBox.Text)

1. Asak2$)kla1015QAXKFskfa332aSJ2(Ska@Skljcmcel3p.lq,aowpqaskla2@)Skx.:Pdm^),dfs;

what i want to is convert this string to something like this

2. JXK2LB AP2WXB S1P0XE ZXPA3H X1LAKW DOXPS3

both 1 & 2 the above strings are fictitious (i made them up to make my point clear)

I am trying to make a licensing system for my VB 2010 express application. (2) above will act as a serial key which can be derived from (1) which is an encrypted form of something unique of the client computer.

I will then confirm the (2) from the client.

VS 2005 Entering Numeric Values Using Combobox?

Apr 21, 2009

I would like the user to enter positive numbers (decimal or whole numbers but no fraction) using combobox. However the user can only enter the numbers using a number key pad built in the combobox. The number key pad will appear once the user click the down arrow of the combobox (I am not sure if there any predefined feature built into vb.net 2005 that has this property). The number key pad should contain the numbers 0-9 and decimal(.).

Sorting - Combobox - Auto-complete Behavior For Numeric Values?

Feb 21, 2012

I have a problem with the auto-complete behaviour of comboboxes in VB.NET (with the .NET framework 2.0).I am using a combobox to type in numeric values, and its DropDown list to suggest possible numeric values. This list is sorted in ascending order, for example {"10","92", "9000", "9001"}.The combobox properties are set as follow:

AutoCompleteMode: SuggestAppend
AutoCompleteSource: ListItems
DropDownStyle: DropDown
Sorted: False

The DropDown list is simply filled like this:

myCombobox.Items.Add("10")
myCombobox.Items.Add("92")
myCombobox.Items.Add("9000")
myCombobox.Items.Add("9001")

When I don't type anything, the order of values of the DropDown list is correct, in original/ascending order. However, when I start typing something, the suggested values in the DropDown list get sorted (alphanumerically): if I type "9", the list of suggestions becomes {"9000", "9001", "92"}.I would like to prevent this behaviour to get the values of the list in the original/ascending order. I can't figure out how...A possible work-around would be to pad with zeroes the values in the list, e.g. {"0010", "0092", "9000", "9001"} but I would like to avoid this.

Saving New Selection From Combobox To SQL Database?

Jun 17, 2010

I have an app I'm working on with multiple forms. One of the forms, frmLocationInfo, has textboxes and comboboxes which are automatically populated based on a combobox selection from a previous form, frmLocations. I've been able to get any changes made to frmLocationInfo's textboxes to save to the SQL database, however, when attempting to select a different item from any of its comboboxes, it's not saving to the database and instead, I receive a "Procedure or function...has too many arguments specified" error.

Here is the code for the Save button:
'Save changes to Locations db

ComboBox Display On Screen And Saving Content To File

Apr 26, 2010

What I am attempting to do is make a form for a tire shop. I want to put comboboxes on the left side of the form that the employees make choices from. I then want to put some kind of a table or grid looking thing on the right side of the form that will display their choices so that everyone in the shop can look at it see that "John is on bay 5 until 3:00pm". At the end of the day I want all of the combobox choices to save to a file..I dont really need the table or the grid thing to save..just the choices. If I want to do this, do I need to use that gridview tool? or can I make my own table thing to display the choices in.

Numeric And Non Numeric Data?

Jan 22, 2010

I am reading a data file and storing them in an array of string.Data is random, could be like "1","2","133,18" but sometimes there can be missing values like "?".Once I load the data in the array, I want to check if at least a majority (like 60% of them) are numeric values.If yes, then I wanna track down the higher and lowest value in the array, and output a range of 5.Loop through the array

If 60% of them are numbers (integers or decimals) then find highest value, find lowest value end if produce range

If for example lowest = 1 and highest = 100, range of 5 means 0,20,40,60,80,100 (so 5 ranges are 0-20, 20-40, 40-60, 60-80, 80-100).Also if the ranges turn to have decimals due to weird numbers, I would like to round them up.My problem is, in order to find highest and lowest when there are non numeric values in the array like "?", how should I handle those? I was thinking of something like Double.NaN but I would have to have an array of doubles.
