generating a catalog number for a library system?It is one of the requirement of the panel in my thesis, though its not fits correctly but atleaast, there is suggestion given in a generated catalog.
View 3 RepliesAnyway, I'm primarily a web developer so I'm only really fluent in PHP and everything else it entails.For my assignments the examination board suggests Visual Basic, so I'm just needing a little help as I'm not too great at it yet. [code] How could I ensure it generates a number 1-13 BUT doesn't ever generate a certain number, e.g. generate a number 1-13 but NOT 7.

View 7 RepliesI'm Trying to make a piece of software where You enter a number and the computer measures the length of the number, and then generates random numbers to match the human number. It will then count the number of guesses and the time taken. However it always comes up that there was a infinite loop "An unhandled exception of type 'System.StackOverflowException' occurred in System.Windows.Forms.dll". I have searched up how to do this and I can't seem to find out how. I think I just put my wording wrong when looking it up. My Software Has Has 2 TextBox, 2 Buttons, 6 labels (4 just to make it user friendly) and a timer.
Here is the Code:
Public Class Form1
Dim TimeTaken As Integer
Dim GuessesTaken As Integer

I'm supposed to make an app where computer generates a random number using a function and then the user has to guess the number. If they get it right, they see a picture.... If they get it wrong the loop keeps going until ten guesses are up.. I'm running into quite a few problems...
1. I don't know how to tell if the photo will show up if the number is right because right now I have it set to false in the form, so it dosen't show up but in my loop I included the code that SHOULD allow it to show up if both numbers are the same.... Not sure if this is correct...
2. I have a textbox that is supposed to keep track of the number of guesses but the message automatically becomes Game Over and the guesses go up to 11 as soon as I click the Are You Right Button?
3. When I try to debug, my app freezes and I don't know why...

I am trying to write a random number function that can just be called from my main module to generate different random numbers. I have tried this several different ways and I am having odd results. Approximately 19 times out of 20 the numbers come back exactly the same, but approximately 1 in 20 they come back as two different numbers. Im using Visual Basic Studio 2008. Here is the code I have so far, or rather, the current version of my many tests I have been running to try and figure it out. Sometimes it takes many runs of the program before the two seperate numbers apear.I've been researching it and have come up with nothing so far.I know I could put them in the module section as two different randoms and it works, but I get extra points if i use a couple classes in my program.This is the main module.
Module Module1
Sub Main()
Dim randomNumOne As New RandNum[code]...........
I've created code that generates a random number and validates the users guess to see if its correct. I think the code is good but i'm not 100% sure. I need to add additional pieces to the code and i'm not sure where or how to do it. allow the user 10 guesses. after 10 guesses disable the ability to make more guesses if the 10th guess is wrong count each guess entered & display the count as it increments display each guess along with its returned messaeg into a list box. when the user gets correct answer provide a box to allow them to play again. Re-initialize variables back to their starting status.
a. If the user correctly guesses the number in less than 5 guesses display "Either you know the secret or you got lucky!" in a message box. b. If the user correctly guesses the number in 5, 6, or 7 guesses, display "Ah Ha! Do you know the secret?" in a message box. c. If the number of guesses is 8 to 10, then display "Try to do better next time." d. If the number of guesses exceeds 10, then display "You have taken too many guesses."

I am making a program which generates a random number between 1 and 10 and when 7 appears it is suppose to tell you how many tries it took to get the number 7 and then end the application. This is the code I have used:
CODE:
This code only generates the number 7 and exits the application, each time i click the random button but i want it to show the other number it randomizes too for example 1 2 3 4 .. etc, if u dont understand, please try it, but im trying to say, when i clikc random it just says number 7 (does randomizing in background) and tells you how much tries it took but i want it to show the other number it randomized also and when 7 appears, then exit the program

I'm working on a program to catalog MP3s (I know, it's a tired thing that's been done to death), and want a better way to determine if a file has previously been added to my database. I have two datasets that are structurally identical. The first dataset is populated from the database and the second is populated via the application during the scan.
I then compare each record in the second dataset to the first with the following code:
Private Sub CompareDataSets(ByVal dsOriginal, ByVal dsNew)
Dim dv As DataView
Dim sFileName As String
Dim sPath As String
Dim bgFileSize As Long
[CODE]...
This method seems terribly inefficient and I'd much prefer being able to do a join of sorts off the two datasets and delete all records from the application populated dataset where there is a match.
I'm looking for a decimal to alphanumeric number base converter library in Visual Basic that does not use recursion. [url]...
which includes a demo app but discovered that it uses recursion. The problem with it using recursion became apparent when I attempted to integrate the library into my own Visual Studio Express 2010 Visual Basic project: I got a stack overflow exception.
Now I could consider increasing the size memory allocated for the stack but it might be hard to determine what this would be, given that the recursion depth might vary depending on the value to be converted.
I created an application with some Crystal Reports. I published the application and installed it on the machine which is my develop machine.

It generates a windows error with no description.

View 3 RepliesI am building a form that will load individual items(from individual files) or a catalog of items(from a list of items). I then click the item I want to use to select it. Everything works correctly, when I click an item it selects the correct stitch. The only problem is, it doesn't display correctly when I load from a catalog. I can open individual items and it works fine. When I load a catalog it doesn't display the images correctly.

Basically I am creating a Windows Service as an 'updater' program to update all my software packages. Whats going to happen is every piece of my software that is installed in its program folder will have an Update.dll this DLL will be a library to do with the update of the software.
There will also be a database in the Updater program folder which will contain a list of all my installed software. So when the service starts it will open my 'database' which will load the paths to all my installed software to a string array. Each path in the string array will have a Update.dll in the folder.
What I need to do then is is in turn call a routine called StartUpdate() from each of those Update.dll which will then do all the work. So the service itself is fairly basic and doesn't really do much I just need to figure out how to access DLL's when I don't actually know what ones will be there while programming, Reason I am doing it this way is to support my future software programmes without having to update the updater.
