View 4 RepliesI have to provide an Excel file as an output. I have to color some of lines and make them bold.The input is based on a dynamic list (in memory) and it also could be based on CSV file that I'm already provide today (based on the same dynamic list).I'm wondering what would be the most efficient way (in terms of performance) in order to provide the colored Excel output?Should I export directly from dynamic list into Excel - or - Should I export from CSV into Excel ?

View 3 RepliesI have two listboxes: lstStates and lstOuput
I have cut and paste the fifty states on one box in the order in which they entered the union. I have two buttons, one to alphabetize the states and one to reverse alphabetize the list. Here is the code for alphabetizing the list:

lstOutput.Sorted = True

How can I put the list in reverse abc order without using an array? I've tried a variation of the above code, but it did not work?
so I am working on a program with items entered into a listbox. Then when the user clicks a button it will randomize the listbox items in just a random order obviously. I have tried adding it to an array and everything but I ended up just having to start over now because I couldn't find a solution. I can save the contents and everything I know how to do that it's just randomizing the items that I am struggling with. I have searched high and low and have yet to find a conclusion to my problem.

I have made an employee list and linked it to an Access database. The initial problem I was having is that in my program I had to link their ID's and names so if you click on an employee in the listbox, his or her's ID would automatically display in the textbox below. Since I did not know how to do so, I decided to make an array and store the ID and names separately while the listbox is being compiled. And so, the form became linked and adding became easy to code.But my problem came in deleting an employee. When deleting the name should be removed from the list, but this is where the order of the arrays messed me up. How do you maintain the order of the array? Here is the code I used. I dimmed 'count' as an integer and it is responsible for keeping that order.[code]You will see Staff_CodeTextBoxes etc. and info_Staff_CodeTextBoxes. etc.These text boxes (not visible to the user) are responsible for holding the data while the array takes the data from it, or adds it's own data to it.

am planning to write a simple program which reads two binary files and apply a simple math function ((file1-file2)/(file1+file2)) then outputs the file (file3). Then the user selects the file (file3) outputted as an input and the program again reads the file and apply another math function ((file3 - 0.2) / (0.5 - 0.2)) to it then output the final file (file4).I would like to eliminate the user input or at least minimize the user input. In other words, the user should execute the program once at the beginning and the program should do the rest. Basically there will be 2 form applications in my program. I want to make it automatic in a way that the program will select two files itself (the user should not select) then output the result and then takes that as an input and applies math function etc.My problem is that I do not know how to start the second form application after the first program ends because the second form application inputs the file which was outputted by the first form application.
View 1 RepliesI have 3 classes in 3 separate dll.
1) Class "BaseForm" that inherits from System.Windows.Forms.Form with "MyEvent" declared as Public Event ()
2) Class "MyForm" which inherits from "BaseForm"
3) class "MyClass" which has a public property "ExternalObject" of "BaseForm" type (the private variable is declared WithEvents)
I make the following steps:
1) intercept the Form LOAD event in "BaseForm"
- Instance the class "MyClass", Assign public property "ExternalObject" = Me
- I do a RaiseEvent "MyEvent" in "BaseForm"
2) "MyEvent" is triggered BEFORE in "MyForm"
3) AFTER "MyEvent" is triggered in "MyClass".How Can I Raise event Befor in "MyClass" and then in "MyForm"?
i am working on a college project in visual basic 2010. in my program, i noticed at the last minute that i needed to add a "main" window. in this main window, i want to have all my other forms opened by buttons (i know how to do that part of it).
the problem i keep having is the window with the options to save the information pops up, not the main window. is there a way to easily fix this? maybe a snippet of code, because the only way i can think of is to scrap the project, start over from scratch adding my main window first, then the others.

im trying to make a program in which if the textbox text and the listbox text are the same order, which they are in the picture, a bluie fonted text saying well done appears. However only the red text appears which is only meant to come when the order of the text in both listbox and textbox isnt the same.
Here is the code that i used for this:
listarrays = name of listbox
textbox1 = name of textbox
l is the name of the label for correct answer(blue font)label3 is name of label with red font which should only appear for wrong answer
Dim text As String = Me.TextBox1.Text
For Each item As Object In listarrays.Items
If item.ToString = Me.TextBox1.Text Then

use another textbox instead of the listbox but thats just making itmuch harder for me as I already made the full code working with the listbox. My lecturer told me i need to convert both in string so both textbox and listbox are compatible and i did so (see code above) but the correct label doesn't show?

View 4 RepliesI have a combo box bound to a datasource. I need to change one combo box (of many) to order the items in descending order.I'm guessing I could order the collection in the dataset, but that will mean all my combo boxes will be reordered?
View 2 RepliesI have a databound Datagridview. The DGV is bound to a datatable of a strongly typed DataSet created using the wizard. Is there any way to re order the columns before displaying them eg: the Columns are displayed in the DGV in this other Col4, Col6, Col3, Col1,Col5, Col2
But I want to it to show as Col1, Col2, col3, Col4, Col5, Col6?
I realise that the display order followed the Column order in the database table and by extension, the datatable. I have re-arranged the columns in the Database but the Datatable still retains the old order.
I'm writing a custom DAL (VB.NET) for an ordering system project. I'd like to explain how it is coded now, and receive some alternate ideas to make coding against the DAL easier/more readable. The DAL is part of an n-tier (not n-layer) application, where each tier is in it's own assembly/DLL.
The DAL consists of several classes that have specific behavior. For instance, there is an Order class that is responsible for retrieving and saving orders. Most of the classes have only two methods, a "Get" and a "Save," with multiple overloads for each. These classes are marked as Friend and are only visible to the DAL (which is in it's own assembly).
In most cases, the DAL returns what I will call a "Data Object." This object is a class that contains only data and validation, and is located in a common assembly that both the BLL and DAL can read.To provide public access to the DAL, I currently have a static (module) class that has many shared members. A simplified version looks something like this:
Public Class DAL
Private Sub New
End Sub
Public Shared Function GetOrder(OrderID as String) as OrderData
[code].....
This cleans it up a bit, but it leaves a lot of classes that only have references to other classes, which I don't like for some reason.Without resorting to passing DB specific instructions (like where clauses) from BLL to DAL, what is the best or most common practice for providing a single point of access for the DAL?

We build a class (i.e. Server) and create a LOAD method that loads a dataset with all the details of that object.We need all that information sometimes... but what about when we only need one piece of data from that object (i.e. webserviceUrl).Should we build classes with a bunch of scalar methods that get back single pieces of data as opposed to only getting ALL the data and then only taking what we need?It's a waste to get all the data when we dont always need all of it but it also will take longer to write the extra methods..
