Produce A List Of Products Stcked With Their Initial Stock Levels?
Jun 19, 2011
I'm trying to make the following snippet work in VB6 but it's one error after the other. can anyone make heads or tails of this?
Basically i'm after a little proggy which will store the names of a couple of products, calculate product code (first three and last three characters of product name) produce a list of products stcked with their initial stock levels, allow info on products be search for, allow the products to be purchased.

I think (?) this is about object design, and perhaps about structural and/or creational patterns. But a bit hard to say when I only know a couple of patterns yet.[code]But... what if we INSTEAD want each Product instance only to (in some way) refer to one instance of a specific list of Components. So we wan't to save the products list to one file, and the components list to another file. Then would I build the objects the same way, or different? So let's then say we have now Class B as below. [code]
1. Will not need to update each component variable of the products list when the components list changes.
2. If the Product object shall be shown in a DataGridView, for editing properties, it seems easier to implement the selection of the component property.
Is this wrong approach? Is it suitable in some cases, and if so, when? Are there other solutions I perhaps am not aware of that would be appropriate? Is this about structural design patterns? and if so, can the alternatives above be catagorized to some pattern type? I don't really know exactly what I'm looking for.. But I think probably I'm looking to understand whether the object design will be determined by the way the objects are saved.. And if i shall save the objects by serializing to file, vs saving to a database, would I create the business objects differently?

I'm basically brand new to LINQ. I've seen some examples that allow me to strong type objects using LINQ but I don't really understand them because they're in C#, which I guess lets you do different things with LINQ(I think?). [Code] I just want to get a list of all the products from the XML doc and put them into a Generics list.

I've got 2 seperated programs.
One is a program where you can select a product and select how many of them you want. Then the total price wil be displayedin a label. And the list of selected products will be saved in a .txt file.
The second program is an Edit program. The user can edit his selected products. Here he can change the total of a product.So if he had selected 1, he can change it to three or something. When the user clicks the button Save. The changes will besaved in the same .txt file and the total price will also be changed and displayed in program one.
Program one is compleet.Program two has problems and here i need your help:- the user can't make a change in the numbers, seems that the textbox is read-only or something. How to solve?- Then when i click save, the changed must be saved in the .txt ( i can't test this yet because no changes can't be made)- the total new price must be showed in program 1 (i think i programmed this well, but can you take a look)
Here is a part of my code of program 1:

I'm trying to create a VBasic executable to read a SQL server database and produce a mailing list.I have the SQL routine working fine and had set it up as a stored procedure, but I've just discovered the manager I've written this for is an Access-type and does not have SQL Server installed on her machine. So, I figured I'd make a front end in VBasic.
Dim con As New SqlClient.SqlConnection
con.ConnectionString = "Data Source=mySQLServer;User ID=Username;Password=myPass;"
con.Open()

I'm trying to make a game in Visual Basic, but I can't figure out how to add in different levels.
Essentially, what I'm looking for is the Tab Control, minus the tabs. On a different note, is there a way to make a group of controls? Like instead of
TextBox1.Text = "Hello"
TextBox2.Text = "Hello"
I could have something along the lines of TextBoxGroup.Text = "Hello"

i have a login form and it has 3 user levels - admin, manager & accountant - which have limited privileges using the system. For ex., if admin logged in, this user can access the whole system; if manager logged in, this user can only access the employee records; & accountant user can only access the payroll.
i actually have the idea but because i lack knowledge about vb.net, i don't know how to code it.
[code..]
At the main menu, buttons are enabled & disabled depending on the user level that was entered.

I'm looking for a recursive subroutine.I have the dataset from sql-server with in the datasource-table a parent- and a child-column.
I made a routine to put the parent-nodes in the tree.The problem starts with the childs over so many levels.I can write it out but it is to much code, I'm sure it can be done more efficient with a recursive subroutine.
.tv_Ana.Nodes(A).Nodes(B).Nodes(C).Nodes(D).Nodes(E).Nodes(F).Nodes(G).Nodes(H).Nodes.Add(Trim(sLev_nI + "-" + row_nI("MidCod").ToString()))
The tree will be about 25 levels deep.A few days ago I saw a recursive subroutine to fill the childnodes without the above difficulty to write alle the levels in code.That example I cannot find it any more, but it had a line of code more or less like this here below:
Dim
Nodes As TreeNodeCollection = tv.Nodes(A).Nodes
but it doesn't work yet!

I have a requirement to create a multi level treeview in ASP.Net (with VB) but I am completely stuck on how to start this. Currently my treeview is a fixed 2 level approach but now I need to rewrite this to be more dynamic and support extra levels being added into our database tables.So this treeview needs to support as many levels as needed without having to rewrite any code each time we want to add new level, Ideally we will just insert the data at the database level.I think I have the database part designed correctly, I created 2 tables Menu and MenuItemsMenu has 2 columns ItemID and ChildIDMenuItems has 2 columns ItemID and Description Doing this query:
SELECT
menu.Item_ID,
menu.Child_ID ,

I have build a program until now with an MySql database. The programs add records for the customers and the products of the company(Its works perfect).. I am trying to build now the Orders the last part of my project but I have a little problem.. First of all I need 4 different type of database:
Cash
Credit Card
Check
Debit
Price Offer
This is the the type of the payment. The user must add the order by the payment of customer so we need to seperate each one.. Unitl here I am fine::
Now, my serious problem is with the order table:: If i used the code that I use for my other adding records (like product and customers ), for each order it's add only one product!! BasicallyI need to be able to add multi products and the user have the ability to change the price of one product:: for example "to make an offer for some special customers" without change data into the database of products..Thats has a lot of typing code but I need a base to start since I have a little bit of confused. At the end am trying to load data from database customers into text boxes:: for example the user select one name that loaded into a combobox and then appears the city and the mobile into a text boxes I build a code below but it's works only One type, actually fill the text boxes but after I clear all the boxes and try for a new customer or the same isn't fill anything.
Dim ServerString As String = "Server=localhost;User Id=root;Password=root;Database=test" ''Sting Server
Dim SQLConnection As MySqlConnection = New MySqlConnection ''SQL Connection
Dim Sql3 As MySqlCommand = New MySqlCommand("SELECT * FROM customers", SQLConnection)

With a steady tone feeding my audio input jack, the VU meters jump and bounce about 30%. I can also see the problem in the byte array of the capture buffer. I am running 8 bit mono so there isn't a chance that I'm getting a byte swap in a 16 bit word. My on board sound card is "Realtek HD Audio Input", direct sound 1.0.2902.0 and XP. Here is the real kick in the head, if I run anything that captures sound using the winmm library or if I use the winmm library in my application along with direct sound, the meters become stable. No errors are reported. Although I have written this in vb.net, I download another persons application that was written in C++ that uses direct sound with the same bouncing meters. I used the VU meters in Audacity to look at my audio levels and they are stable.

I am working on a multiple choice quiz, admin screen, student login screen where they choose their level of difficulty. I have been able to start the quiz, have the questions and answers filled, user answers question, check if correct or not, if correct then the score is incremented.I am able to set up a variable for 'level' and want to write some code so that whatever is selected then that table / questions will be selected and displayed to the user.
The way I'm thinking at the moment seems very long winded. I think I'll have to write an IF ELSE statement/case statement for each of the 'navigaterecords' and the sql statment for beginners, intermediate and advanced.Assume there is a variable 'LEVEL' - have not actually done this yet. Where the code refers to 'advanced' is where I have been trying it out to select questions from the advanced table.

I want to make different levels of access for a vb.net program i'm writing.I have a database called "stratocast". I want to show a specific form for entries in this table with "IsManager" checked and another specific form for those with "IsAdmin" checked.Im using MySql server and visual basic 2010 express
EDIT:To clear up any misconceptions about my post, ill explain further: In my vb.net application i have a login form with two textboxes; One for the username and one for password. I also have three other forms, one is called "frmAdmin", another called "frmManager" and another one called "frmEmployee".
On my database i have a table called "employee" with columns called "name", "title", "IsManager", "IsAdmin", "Username" and "Password".
IsManager and IsAdmin are both Boolean columns
This means that their values can only be 0 or 1 and the result is displayed as a checkbox.When the employee logs into this applcation i want it to check whether or not the employee is a manager, an administrator, or just a regular employee with no additional rights. If the employee is a manager, i want to show "frmManager". If the employee is an Administrator i want to show "frmAdmin". And if the employee has no additional rights then i want to show "frmEmployee".
I'd like to keep the configuration for access level checking confined to the one table but if it's better to have separate tables for each level of access (ie: tables called Admin,Manager, and Employee) then ill consider that too.
