Category And Subcategory In .net?
Jun 4, 2011
how to create a sub category in vb.net? well I'm thinking of building a sales and inventory system of computer parts and peripherals and here's the logic. I'll be assigning each of them category like for example:
Componenets[INDENT]Peripherals[/INDENT][INDENT]Networking[/INDENT] - Processor[INDENT]- Chasis[/INDENT][INDENT] - Router[/INDENT] - Memory[INDENT]- keyboards[/INDENT][INDENT] - Bridge[/INDENT] - Storage[INDENT]- Speakers[/INDENT][INDENT] -Hub[/INDENT] - Optical Drive[INDENT]- Flash Drives[/INDENT][INDENT] - Switch[/INDENT] - Graphics Card
There you go. and the main categories are: Componenets, Peripherals, Networking and the Subcategories are with the -(dash) on their names if you have an idea also on the database structure please give me also some tips about how to construct the database tables.

I am using an asp.net Datalist control. I have a table titled 'Category' with two columns 'Category Id and Description'. When I display the results on my webpage the 'CategoryId' number comes up and not the Description. I want the Description that corresponds to the number. I want to write it to my label control 'lblCategory'. Using ADO.NET I am having trouble with what to put between:

I am writing a basic blog application to learn mvc 3. I have problems retrieving posts by category. The url looks like /Blog/Browse/Category_Name. I can get the posts if i hard code a value for category. So it would seem that Category_Name is not getting pass to my EF statement in my controller. the category had a period in it so it was not matching.

I can't seem to figure out how to write this query properly. I've tried various combinations but nothing's worked yet.Below is the relevant portion of my database model:
I need to select the products that match a given Category and Group, and that match a given Year, Make, Model, submodel. This I've done below: ItemList = From P In gDataContext.Products.Include("Groups").Include("Groups.Category1").Include("LookupYearMakeModels") From G In P.Groups Where G.Category = Cat And G.Grp = Group From Y In P.LookupYearMakeModels Where Y.Year = YMM.Year And Y.Make = YMM.Make And Y.Model = YMM.Model And Y.Submodel = YMM.Submodel Select P

I work with a large shared mailbox within which several individuals each have a folder of their own. I am trying to develop a tool which will monitor how many emails each individual has in their own folder including a breakdown of what categories have been applied to each email (IE In my Subfolder there are 20 Emails - 10 Blue, 5 Red).I have already coded a prototype but so far I have only been able to get a general count working not a breakdown of categories.Does anybody know if this is possible? I have searched a see lots of code for setting the category with VBA but none for querying it.

The combo box will show the category. Suppose there are 2 categories A and B. When we click on A then the code given inside 4 buttons should work. I tried in this way ,I checked the condition of selecteditem based on that added all 4buttons sub code. But it shows blue underlines.
I did in this way: If ComboBox1.SelectedItem = "A" Then Private Sub Button1_Click....
[CODE]............
Like this I have used 3 more buttons. How can it be done?

I wrote a VB 2010 app on a single core processor utilizing performance counters which runs fine. However the release exe fails on my quad core, trapped by the OS on its first access to a PerfCtr. I've loaded VB Express Studio into the quad core
and when running the app in Debug I get this error "Cannot load Counter Name data because an invalid index was read from the registry." Similarly, adding a counter to the app on the quad machine results in the empty drop-downs for category and it sub fields.
where I can get an update to these registry entries?

I have a DLL with me in which i have created a component class. But as long as the project is open the Tool shows in the ToolBox, but the moment i open a new project, without the DLL project opened along with it, the Toolbox does not show me the Tool/Control/Component Class , which i have created. How do I register my component so that it shows in the ToolBox, other than the usual way of Selecting by Browsing

I'm running into a little problem making one combo box dependent on the selection of another combo box. I'm using a access back-end to this project. I have two tables: MajorCategoryTbl and MinorCategoryTbl , MajorCategoryTbl has PK and description field, MinorCategoryTbl has a PK, MajorID (foreign key), and description field. I have two combo boxes on my form, one that displays the Major description, and one that displays the MinorCategoryTbl description, but the stored value is the PK for both. I want the selection of the minor category combobox to depend on what was selected in the major category combobox.

I'm trying to search files for matches, and depending on what catagory the match is under, do a certain function... Say I have a .txt file that looks like this
[Code]...
Then I have a form with Button1 and Textbox1. Say I type "Cat" into Textbox1 and press Button1. It would then bring up a MsgBox that says "Match found under Animal catagory". But if I put "Three" in Textbox1, the messagebox would say "Found under Numbers catagory".

Let's say I have a menustrip, which has a category "Colors" for example, and in that category there is an option of 20 colors, but I want only 1 to be checked at any one time, now to do that with what I know, I'd have to check every other one of the check boxes and uncheck them in every single click event, is there no cleaner way to do this?

Using Vb.net 2003 Sql Server 2005 Asp.net 1.1..If I were to make a forum site and I had alot of visitorsdaily, like 300,000.I also had many categories such as this site.Would it be better to have a Reply table for each category orhave only one Reply table for the whole site.The same for Question table, although the questions would be numerousit would be smaller than the Reply table.Also if anyone has a Database Diagram,or Schema of a large forum I like to take a lookat one have'nt seen any online for a forum.

My sister owns a small business, and (as a cashier) she is currently using hand written invoices for receipts and records. She knows I have some basic programming knowledge, and would like me to make her a program that would make it easier on her. Ultimately, it's going to log sales, and anything else to make taxes easier on her, which she is also doing manually at this time.
That will probably be a few weeks from now, for now what I want is to be able to have a Category, Subcategory, and Product system using ListView boxes. Ie. In the first ListView will be general categories, ie "food". Under the category "food", there will be the subcategories "pizza", "fish", and "pasta". Under the subcategory fish, there will be the products "salmon", "trout", and "cod". The user can highlight cod, click "add item" twice. The first time adding it to the receipt ListView box with a quantity of 1, the second time changing the quantity to 2.
Now the idea here is to make the contents of the ListView boxes depend on the selection in the preceding ListView box. If the user chose the Pizza subcategory, he would have the products "cheese", "pepperoni", and "mushrooms" in the product list box. If he chose "beverages" on the first ListBox (general category), he would get different choices entirely.
Of course these are not the items being sold, but they serve as good examples. I have a decent start on the program but have run into a few roadblocks. In each ListBox, there will be an "Add *" selection (activated by double click), which * will be the ListView it in. For example, they could go to the food category, double click the "Add Subcategory to food category" list item, bringing up a dialog asking for the subcategory name. They could then, in that subcategory, double click an "Add product to * subcategory" list item, bringing up a dialog asking for the item name, price, and flags such as taxability (some things such as services are non taxable). In addition, I want the user to be able to double click an existing item, removing it from the list.
I have a good start on the program, the interface is mostly done. My next step is to create some form of database to store the categories, subcategories, and products she adds. I could probably get it to work in runtime, but it would be a shame to have to redo it every time she restarts the program But this is where the roadblock is. I don't know what to do at this point, I've spent hours on Google before coming to this site. I will include the source so you can see where I'm at, at the moment.
