I'm doing a parking system. but my problem is how can I automatically detect the car plate number when i picture the plate number of the car?
View 6 RepliesSo I have to make a program that will Generate 500 random 6 character license plate numbers and stick them in a list box. Then I have to be able to search for them. But it has to be a partial search so when search is clicked it should loop through the list box and compare each value with the partial.
For example the search term "in" would return things like "indigo" "running" "bingo" "indian" if they were in my list box.
[Code].....
When the search button is clicked the program needs to take whats in that searchBox and compare it with the list box. So it will have to loop through the same number of times as there are terms in the list box. Any matches need to be displayed in the answerBox (text Box)

View 10 RepliesI am trying to figure out a better way to basically predict a random pattern from a previous set of numbers. I figured the best way would be to use a for next loop and try different random seeds until a pattern matched, but it seems that it would take forever Lets say you had 3 random numbers: 2, 5, 12
Code:
Dim RandomGenerator as New Random()
Dim FirstNumber as Integer = 2
Dim SecondNumber as Integer = 5
Dim ThirdNumber as Integer = 12
[code]....
The above code does work to an extent, the problem is it takes so long to process. Is there any way to feed in the random numbers and have .net spit out a seed that matches them?
I would like to know how to detect a two digit number within a string.

I am currently having trouble detecting the number of rows in the table in sql database. I have one column as auto increment, and one column that will show the blkname. But everytime I delete off one row, the program cannot run saying that there is no row at position "up to the latest number". Then, when I try to insert back the row again, the program also gives me the same error. I think the program probably cannot detect the number of rows correctly as it cannot like detect if there is 5 rows in the database and if you delete one row, it will give me the error. The above method is the same if I used the auto increament column and without.
The code that I have wrote so far is :
'AUTOINCREMENT
Dim n As Integer
Dim inc As Integer
Dim numbers() As Integer
Dim StartFrom As Integer
Dim EndAt As Integer
Dim MaxRows As Integer
MaxRows = ds2.Tables("CustDetail").Rows.Count

I have searched on google and asked friends, but have not figured out a way to add dashes while a user is typing either a phone number or a social security number or something of the like. I am using Visual Studio 2008, VB Windows Form. This is not for homework but I enjoy adding things to certain projects and thought this would be neat to incorporate into one of mine. I am also curious about allowing the user to enter the first three numbers for their area code and then send the focus to the next text box so that the user can type the rest of their number. I was thinking I could do something with the text box text entered event procedure where I would send the focus after three characters entered. Not 100% on the entire idea or if there is an easier way.

View 5 RepliesI'm looking for a way to assign a number to either a picture box or label. Not sure what one i will be using. Would it be something like this?
[Code]...
I have a number of images that I want to select a random number of and populate that number of picture boxes either dynamically or that already exist but can't think of the logic that would do it.
I considered dynamically creating them but don't know of a way to name them uniquely. I tried using pcbx& a variable but it didn't like that. Placing the image inside picture boxes that already exist, I couldn't think of a way to differentiate between them without what seemed excessive repetitive coding.
I'm using MS ACCESS for my dbase..i have a tblborrow where you can find transac_num ..now, i have in my form a label which here, you can see how many transactions you have done already(i'll name it sa lbltransacno) and a save button..what i want now is that.. every time the user save a transaction.. the lbltransacno will automatically go to its next number.. but of course.. the user should fill up the information needed.. if those are not filled up, and he click the save button.. the transaction will not be counted.. how to code it?

now if I add 10 names in the table from (1-10) =123456789 10 then I deleted name number 6 the IDD field will renumber it self from( 1-9)=123456789 instead of 1234578910 so in reports and queries the names will appear numberd from 1 to last number with out missing numbers in the middle of numbering I use in MS-Access code which does this perfactly

Still working on a very simplistic poker game and I'm struggling with getting the code to show my cards in picture boxes. I currently have 12 picture boxes set up on my form and when clicking the "deal" button I created on the form, I would like a random number to be generated from 1-53 and based on the number returned I would like a picture of a playing card entered into the picturebox. I would like this to happen in 10 picture boxes. So playing cards will be shown in the picture box on 10 of them and a the card back on the picture box 11 and 12. After hitting a second button, I would like the 11th and 12th boxes to display a card from the deck.
With all that being said my questions are:
1. How do I associate the random numbers with my playing cards? (I have my card pictures in a file on my computer.)
2. How do I get the picture of the cards into the picture boxes? What would the code look like?
3. I have a button to clear all the cards, but how to I program it.
I want to know how to load a picture instead of a string or number in a textbox.click?

View 6 RepliesIn VB.Net, is there a way of auto-detecting the culture of a string representation of a number? I'll explain the situation:Our asp.net web site receives xml data feeds for boat data. Most of the time, the number format for the prices use either a simple non-formatted integer e.g. "999000". That's easy for us to process.Occaisionally, there are commas for thousands separators and periods for the decimal point. Also, that's fine as our data import understands this. Example "999,000.00".We're starting to get some data from France where some of the prices have been entered with the periods and thousands separators the other way around as that's the way it's done in many European countries. E.g. "999.000,00". This is where our system would interpret that as nine hundred and ninety nine pounds instead of the nine hundred and ninety nine thousand pounds that was intended.
View 2 RepliesI have a problem with a sql query. Through the query I am trying to search database for any occurrences of string (can be anything) in a column using the SQL LIKE command. The problem is that it works fine for most of the strings say john, jim, ji"m , but does not work when i include the following characters which are ( ' , { , } , and a single quotation mark). MYSQL query takes care of these special cases by putting them in [] block whenever user enters them .But i am getting the following error when i go to query the database using the GetSelectCommand() in VB.NET
Exception Details: System.ApplicationException: Number of values provided must be equal to the number of placeholders in query.I have checked the query over and over again .. but its fine .My database server is Sql Server 2008.So my application throws the exception in this command:
Using reader As MustDisposeDataReader = _
pmSystem.DatabaseManager.GetSelectCommand(selectStatementBuilder.ToString(), New Object() {})
Where MustDisposeDataReader is an instance of a class in an internally developed library, which inherits from System.Object. pmSystem is an instance of the class PlanManagerSystem which implements the commandlayer. GetSelectCommand() takes the select command

I am trying to filter a dataset using a number different inputs, selected by a number of check boxes. I have all the text base rowfilters working, but I can not make the date filter work unless I hard code the datetime into the code. The database is MS Access and I am using VB2008 to show the data. I would like to be able to use a DateTimePicker to set the filter date (without the time part) Also I would need to remove the time section of the datEnterDate. I cannot change the structure of the database fields. Also the datEnterDate is MM/dd/yyyy, because I'm in England I would like to use the format of dd/MM/yyyy if possible

I am attempting to create a game in Visual Studio 2008 that allows a user 10 attempts to guess a random number between 1 and 50. I have a label box in which I would like to display the remaining guesses as they decrement. The code so far appears below.
My two (I am sure very basic) questions are:
1. How would I pass the random integer generated through the Generate Integer function to the AmIRight button's click function? I was trying to decrement the counter each time the "Am I Right " button is pressed.
2. I would also like to evaluate each "guess" when the "Am I right button is pressed. Is it possible to nest a Select Case statement in a For Next Loop?

i wanted to create a random number generator that iterates through a series of number between an upper and lower bound. say between 1 and 100. Basically I want the number generator to pick the numbers randomly and then display them until all 100 numbers are picked without any duplicates. so thats easy I can code that. But what I don't know is how to show those numbers in the order they are generated on a windows form. So i have basically a variable that I will let be changed 100 times (or however many times I want, I don't want their to be a size constraint just using 100 as an example) and each time the number is generated I want it displayed on screen (in a list or something not sure what. Hopefully some type of scrollable list) and each successive number also to be displayed in same format beneath it so that I can see the list in its entirety. What type of form control do i use for that? I could do messagebox.show for each iteration but then user is required to hit ok after each iteration and that would obviously be a bad idea if user selected a large number to work through. Anyways, code isn't exactly necessary just point me in the right direction, i.e.what control (if any) to use.how to format the change in data?

I am trying to make a basic ATM system, iv got all the interface done and I have made the link to my SQL database etc. the part i'm stuck on is how I can run a check to see if a bank card number matches up to the users PIN number. To simulate the user putting a card into the machine I've used a combo box, and that lists all the cards, that haven't been flagged as confiscated (there's a column in my ATMCards table that I can set to true or false) then after the user has selected a relevant card there's another text box where they can enter in their PIN number.
Now what I want to do is, if they chose the card number 1234567890123456 in the combo box and they enter in the PIN 1234 into the text box, then, after clicking the check PIN Button if the pin is correct they need to be taken to another from where they can check their balance etc., and if its wrong they got three attempts after which point i want to flag that card as confiscated.
