I am working on a project that requires me to read a table of items, and then display the items as button with a photo for a POS system. Any suggestions on how to implement this? This project is using .NET 3.5 and a SQL Compact 3.5 database as a data store.I am using windows forms over an MDI form.
View 5 RepliesI've been trying to get some PictureBox'es to appear and disappear dynamically. Here is my code I've been trying to get to work:
Private Sub Container_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim Image As New PictureBox
[Code].....
Obviously, this isn't how I started out. But I've been trying everything I can to get it to actually display. If I have a PictureBox with exactly the same properties, it displays when I tell it to. This way, it doesn't. I even created an entire class and used that - nothing. I'm guessing it may be the fact that I used a Dim statement, but I'm still a teensy bit novice-y to certain aspects of VB (in particular, Image handling).

View 11 RepliesI am using a ListView control to display Pictures along with description and caption. I used to save the full path of the image in the url field, so when I display them in the ListView I don't need to edit anything. Now I am using something like:
HttpContext.Current.Server.MapPath("~/photos/") + savedURL
How can I edit my ListView to make it show the images?
I used to do the same to GridView when in GridViews RowDataBound event I manipulate the contents like:
Dim photo As New Image
photo.ImageUrl = "~/photos/" + e.Row.Cells(TheCellNumber).Text
e.Row.Cells(0).Controls.Clear()
e.Row.Cells(0).Controls.Add(photo)
I have around 1300 jpeg's that need to be renamed based on the value in an excel spreadsheet.
What I need to be able to do is parse each jpeg in a directory, compare the filename to a list of names in a column in the spreadsheet and if it exists, rename it with the corresponding value from the next column and then move to the next file and so on and so on.
I have the following code for opening the spreadsheet and reading the files but am not sure how to compare the spreadsheet values to the filenames and then rename them:
Code:
Imports System
Imports System.IO
Imports System.IO.File

View 1 RepliesI'll start off with a brief explanation of my situation. I'm doing my A-Level coursework project at the moment and am having some difficulty trying to figure something out. My project is a VB.NET Program that connects to a Database to display/add/delete/update records. At the moment I am having trouble with one particular thing which must be solved before I can move on (and the deadline is fast approaching).
I have a combo box which contains a list of different item types (Which match up to the item types used in the database, but it is not filled from the database). When the user selects one of these options, the list box below must fill with all items of that type that are in the database.
Unfortunately I'm at home so I can't get access to my coding, but I can try to explain what I've tried. I've tried so many things after trawling though what seems like endless amounts of tutorials to find an answer.
One thing that is used in pretty much all of them is the SQL string to select the needed records;
"SELECT ItemName FROM Stock WHERE ItemType = Anime"
Now, this has been used many different ways. I think the way that I'm trying at the moment is to create a new data set that contains the records that are needed for the search. There is already a data set that contains the whole table that is needed for this particular form. I think my most recent attempt was trying to copy the relevant information from the original data set to the new one, but I can't get any coding that isn't incorrect.
Is it possible to be present a context menu when an item, any item, is right clicked in the ListView control? - If so, how?

View 6 RepliesWhen the user clicks the Exit button it closes the forms and if there was an open file it asks the user is they would like to save. But after the application closes there is still memory being held in Processes by the application. However, when pressing the [X] in the top of the form the application closes again but in this instance it is not held in Processes. How do I write the close for Exit to take into account how the [X] works and close the application cleanly?

Someone asked me to add a function when the notifyicon is doublcliked. I figured that'd be easy with the mousedoubleclick event being available. I find out that then both the single and double will then be called. Well that sucks, I want it to only do the one the user requests. So I tried to get it to work:

I want to create a big list box that has lots of default values in many lines so they can then be edited later.Right now I have in my initializer:
Dim counter As Integer = 0
For counter = 0 To counter = totalNumber
listBoxThingy.Items(counter) = ("DEFAULT DETAILS TO BE COMPLETED")
Next
with my list box called listBoxThingy and totalNumber a previously defined constant of how many items I want in my list box.yet when I try to run the code I always just end up with the first list value containing the text.Even if I put a counter=counter+1 it still only gives me the one completed value of my list box?
I would like to know how I can get the list of possible choices to Intellisense for my class object, like it does with MsgBox.For example, when creating a message box you type MsgBox "Test Message Text", vbYesNo, "Test Message Title".In typing that, when you type the comma just before the vbYesNo, it gives you the possible selections for button types in a drop down list: i.e., vbYesNo, vbOKOnly, etc.I have a class called clsKeyState. what it does is turn on/off/toggle key states, such as CAPS LOCK, SCROLL LOCK, NUM LOCK, etc... I have set my property for it as Get/Let "State". When I call it to set a key to on/off I will be doing it like this: KeyState.State WhichKey, On/Off/Toggle.I would like the WhichKey part to automatically display all the possible selections that I define, such as CapsLock, NumLock, Scroll Lock; and I want the On/Off/Toggle to display those specific items also (On, Off, Toggle). I will be using the ability to create these displayable options for many more things in my project than just this one simple class.
View 3 RepliesSo I have a program that is supposed to support a small business. I have the work completed and the professor said it was correct but I wanted to go do a little extra. Basically, on the Order screen, you begin to type the name of a customer/supplier/employee into a text box and a list of names that fit the criteria pops up in a list box (lbMatchingAccounts). When you select it, you can hit enter new order and be transported to the Order Details screen to enter the new order.

I'm trying to create a small program where someone would select one of five items from a list box (Hot, Medium, Mild, Sweet, Zesty). When they select this, they then enter in a qtyTextBox the quantity they want, ie.e, 1, 2, 3, 5,... Then they the Calculate Button, which then the total would go into the preDiscountLabel box, where it would calculate the amount they want * the sale price. Here is the Price Listing:
Hot - 3.19

I want to create a generic list - but I want to specify the type at runtime - is there a way I can do this? using reflection perhaps?Something like this...

, .EndDate = dsResourcesEnd(index).Day}
I have created that anonymous type. Now I'd like to add it to a list of that type. How do I declare a list of that type?
I am using MS Visual Studio 2005 and SQL Server 2000 to develop an application. I wish to make a list of radio buttons when I fetch a particular column from a table. for example, I fire a query that returns to me 10 types of candies, (yummy!). I want to show these candies as options on the form. I want to use Radio Buttons. Now the number of candies are not fixed, it can be any number (less than 15-20). So I wish to dynamically create this 'Array of Radio Buttons' on the form.

I have been trying to figure out how to get my code to work. (It was a homework assignment which has already been turned in but I am determined to get this code to work.)I have a text box titled txtSearch and btnClick.I need to search a list box for a city name and then have it displayed in a message box. If there is not a match then I need to display an alternative message box stating there is no match. City is in the list box starting at 16.The text needs to be case insensitive.I am only getting the message "That is not a valid city." for any entry that I type into my txtSearch even though I know it should be a match.
Here is what I have for code
Private Sub btnFind_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnFind.Click
' Declare variables to find text on txtSearch when button clicked
Dim length As Integer = txtSearch.TextLength
Dim value As String = txtSearch.Text.ToUpper

View 3 RepliesI'm having trouble creating a global array that i can use in other functions.
I have this code right under "Public Class myClass":
Dim LoadedPlugins As Array
Then in a function I have this:
Dim PluginList As String() = Directory.GetFiles(appDir, "*.dll")
For Each Plugin As String In PluginList
Dim Asm As Assembly
[Code]....
Now obviously that doesn't work, how can I add the tmpPlugin to an array or list so I can use it in other functions?
The main thing I need to be able to do is loop through all the loaded plugins and execute the CustomFunction in a separate function than the one that loads the plugins listed above.
