SQL : Get Minimum Value From List Of 3, 4, 5 Digit Numbers But Want Minimum 4 Digit Number?
May 4, 2012
I'm using Visual Studio and table adapters using an Access DB as the backend. I need the minimum 4 digit value. I want to get next available 4 or 5 digit number. And this will change depending upon the users request. Currently I use a table adabpter query. But how would I write a query. I suppose I could do a long iterative loop through all values until I see a 4 digit.But I'm trying to think of something more efficient.
Function GetNextAvailableNumber(NumofDigits) as Long

I just finished this application where you enter a five-digit credit card number, with the fifth digit being the check digit. everything seems to work except, I can't seem to get it to determine that any number is "valid". Every 5-digit combination that I enter returns "The credit card number is not valid". Im using visual basic 2008 express

I'm supposed to write a program that validates an inputted ten digit ISBN number using the check-digit at the end to ensure that the sum is a multiple of eleven. Before calculating this and detecting if the entered number is indeed a valid ISBN, we're required to check the first nine digits and see if they are indeed integers. After this the tenth digit is checked to see if it is "X" (for ten) or 0-9.
With the code I've written it keeps returning false for whether or not the ISBN is valid, even with valid numbers. I feel like its something to do with the hyphens; have I misused the replace function?I'm a little lost on how to make my code work, but I'm fairly certain my logic is okay so far.

I'm looking for a way to take seven 2 digit numbers & combine them into one number to store in a database.The numbers represent hours for each day of the week & I only have one field to store them in. Then I need to be able to take the stored number & decode it back into the original seven numbers. Anyone have any clever ideas how I can do this?

I'm making a project that randomly picks a number from an array, but if it picks a number less than 10 then the number is a single instead of a double.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim N(2) As Integer
N(0) = "0" & 1
N(1) = "0" & 2
N(2) = "0" & 3

Im trying to write a program that will do:
1.The average of the four numbers. This answer will be placed into a text box reserved for that value. This text box cannot be changed by the user.
2.The maximum and minimum values. These will be denoted by changing the color of the largest number green and the smallest number red.
3.The range of the numbers. The range is defined as the difference between the largest and smallest numbers. The range will be placed into its own text box, labeled as such. This text box cannot be changed by the user."
Im using visual studio 2008 and it has to be written in VB

I need a regular expression that will pull 7 digit certificate numbers from a file. The numbers follow the word CERTIFICATE. There could be spaces between CERTIFICATE and the number and there could not be. Here is what I have so far, but it doesn't match if there are no spaces or just one space.

I'm returning a list of database records;
Dim rsPublicChilds As System.Data.Linq.ISingleResult(Of spGetPublicObjectsResult) = Nothing
rsPublicChilds = dc.spGetPublicObject(slintLoginID, lintLanguageID, lintObjectID, lintObjectTypeID, lstrSEOURL, lstrValid)
I get an enumerable list of rsPublicChildObjects that I then convert to an array;
Dim larr_PublicChild As IEnumerable(Of spGetPublicObjectsResult) = rsPublicChilds.toArray()
That then gives me easy access to an array of the objects, so I can then do;
larr_publicchild(0).colMyValue
etc.etc
I'd like to get the minimum value of colMyValue (or any other property of the object that's been created for me) but I can't quite see how to get there.

How I could retrieve the single digits of a 4 digit number to manipulate them in my own way to encrypt the 4 digit number to my liking. Here's what I have to do; take a 4 digit number, add 7 to each digittaking the result and dividing by 10 leaving only the remainder. Then swap the first digit with the third, and swap the second with the fourth digit.

I found a good method of getting the next 4 digit number. How to find next free unique 4-digit number..But in my case I want to get next available 4 or 5 digit number.And this will change depending upon the users request. Theses number are not a key ID columns, but they are essential to the tagging structure for the business purpose. Currently I use a table adabpter query. But how would I write a query. I suppose I could do a long iterative loop through all values until I see a 4 digit.[code]Numbers is the List of All available number from 0 to 99999, basically what's available to use. LineList is my final master table where I keep the long and all the relevant other business information.

I want to be able to enter (type in) data into a combobox as well as picking from the list. In earlier VB there was AfterUpdate event so that I could enter in the data I wanted. Now I have tried Keypress, Enter, and others and they all want just one character or number. If I try to enter a two-digit number it doesn't wait.

Ok, now I have another problem that I cant seem to figure out I now have the "Labour charge section" just incase the service requires one. which in alot of cases it does. So, I have a test box called text box 1, which I want to be able to insert "hours worked" which is a "digit" and then Have a fixed value, of five. Which the user can later change. The number from the box, and the user specified Hourly charge, must then be multiplied to create the total labour charge which will be inserted into a label view. So, my question first, is, how would the user be able to set the hourly charge and then not be able to change it by accident. I was thinking of having a tool strip with an options tab and then setting, and then you use that to fill the info, and have that hourly charge, hidden of the actuall form so that it cant be changed by mistake. Then, on to of that, how would you multiply these two numbers?

I am trying to take a database with multiple entries of 11 digit numbers and run a check sum algorithm that adds the 12th digit to the 11 digits as an output.The algorithm is as follows:
Add sum of odd digits starting with first digit, then multiply by 3.
Add sum of even digits, then add to result of odd digits multiplied by 3.
Take result and divide by 10. The remainder is the check sum which needs to be added to the end of the original 11 digits.
