VS 2010 Get Unique Number For Each Receipt Of Payment?
Aug 10, 2011
I have a database with 3 or more tables. Each Table have 3 or more columns. In one of tables, named "Persons" i have ID column, Name Column, Date Column etc.I like to select one record (opened with click in new Form Window)for printing and give to the person one or more receipt (bill).Every person take every month one receipt of payment.
But every time i like the number of receipt to be unique. For all persons in my table and all payments.
Every payment need to show somewhere in Form for check if person has pay the months before this month.
The start number format will be 00000000 or 00.000.000 or A000000 and next will be +1.
Ask for further explanation.[URL]...I know how to copy text from text box and paste it to file in specify place and print this file.

How would I go about generating a unique receipt number in the following range:
GA00000-GZ99999? I am not allowed to use the 'I' and 'O' letters so GI00000-GI99999 & GO00000-GO99999 would be excluded. Ideally, I'd like to create this in T-SQL but can also do it in VB.Net. This number will be stored in SQL and I can access it prior to generating the next one. They do not have to be sequential.

On Stack Overflow, I found the question Generate a receipt number in this range.In answers (from Adam Maras) I find this code (very interesting for me):
Private Const FirstReceiptNumber As String = "GA00000"
Public Function GenerateReceiptNumber(ByVal lastNumber As String) As String
If lastNumber.Length <> 7 Then
[code]....
But show me error in GenerateReceiptNumber().ow do I use that code to give me a receipt number in TextBox1 when I open this form?The receipt number must be +1 next time with Form_Load.

I am starting to design a payment form that the user enters rent information and any payments/deductions. Should my fields in my table be set to decimal or double? Currently they are ALL set to Currency. I'm trying to add the fields but it don't seem to work. I know this one wont work: You cannot do math operation over string (Text property of textBox is just a string).
HTML
txtAmtOwedThisMonth.Text = txtTenantAmt.Text + txtHousingProgramAmt.Text + txtDeposit.Text + txtPetDeposit.Text
Tried this as well
txtAmtOwedThisMonth.Text = Double.Parse(txtTenantAmt.Text) + Double.Parse(txtHousingProgramAmt.Text) + Double.Parse(txtDeposit.Text) + Double.Parse(txtPetDeposit.Text)

I once posted a question on generating a policy number by table ID and user selctions from comboboxes. [URL]FYI . I am doing my project in vb, that why i posted it here. I managed to do that when i choose a region and product from two different comboboxes i generate a number but now my problem is that whenever i click on the comboboxes a policy number is generated before i save the record, so if my previous nummber was 72100002 whenever i click on the product combobox i generate a number e.g if i click on it five times by the time i save the number would be 72100007. I am using a stored procedure for this. Is there another way of doing this or i might end up with my first record as 72100001 and my second record 72100006.

I have an application that is made for a game that you have to draw cards for. So what I have done is created a random number generator that generates a random number and then using case statements that number is associated with a picture of the card, which is displayed in a picture box. This part works fine. Each time I draw a card it is not reshuffled so I need to store the random number generated and then if that number is generated again ignore it an generate a new number.
Now to complicate matters even further when a certain card is drawn the entire deck is reshuffled and everything starts over again. Here is what I tried... I tried using arrays to store the numbers but I cannot seem to get it to search the array for the number or store the number properly within the array. The array has to be dynamic since the game is expandable and I will be adding more cards to the game in the future.

I am trying to populate an array with all the unique values in a string, to prevent me ReDim'ing an array every time I find a value that not already contained in the array I am trying to create (consumes alot of time), I am trying to get the unique values first so I only have to ReDim once and after that I can simply iterate through the string and the array I have will be the correct size for the unique values I aquire (I am using this...)

I've seen threads on this topic posted before but they didn't come up in the search that I did. What's the best way to get a computer id code of some kind that is unique for each computer so I could use that to create a unique software activation code?Does Visual Basic have any staements that can give you this kind of information.

I'm developing a policy administration system and I need to generate a unique policy in this formart
RP000000/HH
Where R is the Region i select from a Combobox, P is the product the client chooses and the auto generated six digit number and HH is the hour when the record was entered in the system. I want the auto generated number to be the ID in my ClientDetails table in my DB.Here is my code of what I have done so far.They want to be able to tell the region and the product by just looking at the policy number.
Private Function PolicyNumber(ByVal intRegion As Int16, ByVal intProductCover As Int16) As String
PolicyNumber = intRegion.ToString & intProductCover.ToString & "000000" & "/" & Hour(Now).ToString
End Function

I am using VB .Net to access the eBay API and store all completed orders in a database. This database is then fed into a proprietary shipping system, which can not handle an order number larger than 20 characters. eBay returns an order number like so 230407279314-680141236013 which is too long. The order number is always 12 numbers a hyphen and 12 more numbers. What I need to do, is turn this (the result can be alpha numerical) into a shorter, unique order key to store in my database alongside the true orderId (so that this can be referenced by the shipping software instead of the actual order number). The reason for the 20 character limit is the barcode algorithm used. Is there any way to achieve this in VB .Net 2010? This number can be anything unique, so long as it does not exist already (even a good uniqueid function would work, but I would have to query the database to make sure it isn't taken)

I'm using MySQL to store some numbers. One of the columns in the database is defined as unique, but it does allow multiple NULL-values. That is exactly how I want it.ut when I'm trying to load the data into my strongly typed DataSet, I get a error saying that a constraint fails... I do understand why that happens (several rows with NULL-values in a unique column), but is it a way to keep a DataColumn in vb.net unique, but still allow several rows with NULL-values like in MySQL?

I'm creating a radio streaming application, which plays a live stream from various radio stations in a small 'gadget' like application.
The user can add his own custom radio stations, by supplying a Name, a StreamUrl and, optionally, an Image that represents a logo or something of that radio station.The logo will be drawn on the main form when that station is selected.
I need to be able to save these custom stations, and I think it makes sense to use an XML file, which could then look something like this
<CustomStations>
<Station>
<Name>Radio 1</Name>
[code]....
Before I added the support for images, this worked fine, how to store the images. I want the user to be able to select any image from his harddrive, but I don't want to force him to keep that image in the same location afterwards. So I can't rely on the path that he selected. Instead, I want to simply load the image from the path he selected, and then save it somewhere else.
I am storing the XML file in the common application data path which I think is a good place for the images too.The problem is, how to determine a name for the images? I will always have just one image per custom radio station, so it makes sense to me to simply have one Images folder that holds all images, with a unique name.I can see two solutions:
1. Generate a random filename for every image
2. Use the Name of the radio station as the image name
For option 1, I suppose I could just create a string of 16 random characters and call that the filename. The problem of course is that there is no guarantee that I will get a unique filename. Yes, the chances of generating the same name twice randomly are very tiny, but it's still possible, and I just don't like that. How can I ensure that my random filename is unique? I suppose I could always drop the whole thing in a While loop that continues when the new filename already exists, but there must be a better way... Is there nothing in the framework that allows me to generate a unique random filename, in a directory of my choice (so not in the Temp directory...)
I like option 2 much better. The Name of a radio station is unique (there can't be two stations with the same name), so I don't have to worry about filenames conflicting. The problem with this approach is that there are no restrictions on the name. There's nothing stopping the user from naming their custom station "Radio~/aij!""_.fe" or something like that, which is obviously not a valid filename... So, I will have to do 'something' to generate a valid filename from the station name. I could simply remove all non-valid path characters from the name, but then I am no longer guaranteed a unique filename... Suppose there's two stations, one called "Radio/1" and one "Radio1", then after removing the invalid "/" character, the names will be the same and so I will generate the same image path for both....

I am programmatically "reading" e-mails using WebDav. I am also deleting these e-mails when I've finished having my way with them, however, this is causing an interesting problem. Each time I delete an e-mail the original sender is getting a not read response. I have logged into OWA and checked the option Do not automatically send a response but this doesn't seem to help.Is there ANY way to remove the request for read receipt from the e-mail before deleting it?
