Aug 1, 2009

I currently have a list of words in a text file sorted in to alphabetical order and put into lower case, but I would like to be able to also display the line numbers on which these words are associated with.. but only one instance of.

For example,

"This is a random text

As you can see above, I would like to show that "this" for example appears on line 1 and 4. Hopefully tabbed so that it keeps a nice look to it.

How To Properly Open A Image Using Bitmap Class And Dispose It Properly

Jun 22, 2010

I am looking for a code snippet which opens a image, creates a clone of this bitmap in memory disposes this opened image so that all handles are closed.

Usually we can open a bitmap using this[code...]

the following code however keeps the Image File locked until the application is running, any suggestions how to dispose it properly. (So that no handle is left open )

Things i already tried: use dispose method of bitmap <= doesnt work (need to write implementation)
Using Block also doesnt work.

Can't Order The Data Properly

Sep 15, 2010

I have a VB.Net 2008/Access 2007 app that I can�t get to display data in an organized way on a listview. The listview displays the data in the order that the data was entered in the products table. In the SQL statement that loads the listview I put ORDER BY SupplierTbl.CompanyName but it doesn't do it. The listview shows the data in the order that the records were entered in the database. So then I was going to settle for if I can get the listview sorted by clicking on the column header.If I can get that to work then that would be acceptable. So I then implemented the sort routine. The sort works and it doesn't.If you click on a column header then all the rows show the information nicely. The database has an OLE object column for storing images. Customer wants images stored in the database not file paths. When you click the listview the image displays in a picturebox.

The proper images display when the listview is clicked when I use the SQL statement below without the ORDER BY. But when I click on a column header and reorder the display it's no good. If you click on a row in the listview the wrong image is being displayed. It displays them in the order as they were in before the sort. All the other columns look good and are behaving except for the Image column. So that then makes me wonder if my original problem with the ORDER BY is directly related with the OLE object column. Is there something about this data type that I need to know to manipulate it in SQL? My reaction is that maybe since this column is resource heavy it goes by different rules. Can someone please tell me what I need to do to make the end result have some order? This is the SQL statement without the ORDER BY:

command.CommandText = "SELECT ProductTbl.ProductID, ProductTbl.PartNumber, " & _
" ProductTbl.AltPartNumber, ProductTbl.Description, ProductTbl.SupplierID, " & _
" SupplierTbl.SupplierID, SupplierTbl.CompanyName, ProductTbl.Category, " & _

Properly Manage Data From XML?

Nov 3, 2010

I am reading data from an XML file. This local XML file will be updated by another application, and I will need to periodically re-evaluate the XML file, and only import new data into a list box. Furthermore, I want to be able to click on a particular item in the listbox, and display the other values about that particular XML entry.

So, I suppose this is a multi part question. What is the proper way to import only NEW data into the program, what is the proper way to store the data, and how do I associate a value in a listbox with the data stored elsewhere?

I've considered multidimensional arrays, but have been told that strings to char arrays and then back to strings is a terrible way to manage the data, but was never offered an alternative.

DB/Reporting :: SQL Query - Use The Data Properly With Different Forms And Different Controls With Queries

Apr 21, 2008

I am working on a Data Survey Project and first I have a few questions about the different types of databases, and second, I need help querying my tables that have relationships.

1. I need a database that is stand alone. It is just the back end for the program. Simply to hold all the data an employee gets while out on a job. So would I be better using access, or SQL Express? I have played with both, but I do not want a large redistribution to my user machines. When I compile and produce this app does the SQL Database still work without installing any SQL Technology? Or do they have to go in after they install my app, and install Express?

2.Overview: I suppose depending on the first question regarding the database, it might change this question a bit, but none the less...I have 4 tables( using Access at the moment) I will be generating Reports based on data in the database. I haven't gotten that far yet. *Project* is the table that holds all the details that pertain to the job and client. It has a "one-to-many" relationship to *Survey*. So for one customer there are going to be many Survey Records. *Project Type* also has a 1-to-many back to *Projects*. Parts is kind of an orphan, but is linked to the *Survey* table with a one to many. So there can be many parts for one survey. I wanted this table for a drop down box, so the user could just simply select what hardware he was using instead of typing all the names and parts.

So in VS 2008 using the Designers and related Query tools, how do I constrain the Survey Data to one Customer? I have one form that opens from a button that is "New Project" and then there are all the *project* fields listed, so the user fills out the info and hits accept and that opens a new form called "frmSurvey" I need to add some code to the accept button to check what type of project is selected from the frmNewProject and then run a select query based on that. How do I write query statements in the code section of the form, without using the Visual Database tools?

Ill stop here, and get these questions out of the way first. If I could just get a handle on how to use the data properly with different forms and different controls with my queries, that would be great.

The bound field is a phone number, stored in the db as a 10 digit numeric string I need to format this with the standard ()-, and I have a function that will do just that. How can I apply the formatting so the phone number appears in the label properly?

Private Lines As New List(Of Line)?

Apr 19, 2009

vb.net is SOOOOOOO annoying.i am drawing a list of lines to a control. So, I declare:Private Lines As New List(Of Line) Private CopyOfLines as New List(Of Line)In code, I have a custom Class called "Line".

I am wanting to reuse the list called "Lines" so I can start a new list while retaining the old list. So I copy it's contents to "CopyOfLines", then clear the contents of "Lines":

CopyOfLines = Lines
Lines.Clear

Problem is the contents of CopyOfLines ALSO gets cleared! Is there no way to break the connection of "CopyOfLines" to "Lines"? This seems so unnecessary. After all, if I say:

a=10
b=a
a=0
Then (b) will still = 10 while (a) = 0.

Why does vb.NET have to break such simple logic and turn it into a gargantuan issue? I wouldn't mind it as much if the MSDN library would make it possible to find references to "List (Of whatever)", but all I get are references to text in a textbox. It seems that every time I go to the MSDN, I get a convoluted, runaround explanation or simply no documentation of something someone has done in their own code? Where did THEY find the information?
