View 1 RepliesI probably confused memory usage issues with the UI sharing same thread as the processing (as pointed out by MusiGenesis below). However regarding the Memory usage. I am still not able to find VB.net specific syntax, although people have pointed out some great .Net and C# information below (and if I were more versed in those technologies, one could adapt to make work with VB.net).The general concepts are working fine, however I am having issues where the Mem Usage on Task Manager keeps growing as the program is used to load more and more files.On Startup, before doing anything, the VB application has 27,000 K.Once the file is parsed and even after I dispose of the File handle as well as the the data increases a lot. I strip out everything in the code and it still seems that memory in Mem Usage remains captured. There is no rhyme or reason as to why the Mem Usage is growing (i.e. sometimes it can grow by 20 mb when reading a 7mb file, however other times it does not increase at all, when reading a 3mb file). Sometimes, it appers to release some memory when the parsing is complete and other times it just holds.I have looked at .Net Memory Profiler and have not really been able to make heads or tails from that.I have read a lot on internet regarding Memory Management on .Net in General about Dispose and "Nothing" and DataSets, etc, however have not really found anything regarding VB.Net specifically.My General Question is: Are there any good tutorials/books/blogs/etc that show a more in depth tutorial on managing memory in a VB.Net application (i.e. how/when to dispose/close, etc), or does anyone have some specific tips from there experience.

View 2 RepliesI've recently decided to switch from VB6 to VB2008 and am looking for some advice for a certain type of book I seek.Already I've aquired several VB2008 books, but the type of reference book I'm seeking I can't find.For VB6 I have a book called "The visual guide to visual basic". It's a very very very very old book but its gold, platinum and diamonds in one.This book basically takes ALL controls, commands, etc, and in alphabetical order as a sort of encyclopedia, explains its purposes, possibilities, properties together with many examples.
If I was uncertain about a control or command I could simply look it up in this book and almost always find what I was looking for.My question, does anybody know of an equivalent for VB2008?

View 4 RepliesI'm trying to pick up some simple object-oriented programming skills so I am trying my hand at beginner's problem - and I am totally stuck...I'm trying to write a program that will print to a label, the area and perimeter of your shape of choice, dependent on the Length and Width (for Rectangles and Triangles) or Radius (For Circles) you input and the shape you select.
I know how to do this easily with simple event-driven programming, but I'm trying to do this by using classes and inheritance.The idea I have is that you enter in length/Radius and/or width into text boxes (txtLen, txtWid) and then you can click a button to display the Length, Width and Perimeter or Radius and Circumference, and Area.
I'd create a Super-Class: Shapes to define my overarching parameters - all shapes have area and perimeter. Then I would create sub-classes for each shape inheriting the overarching "Shapes" class - dim'ing all of their respective extra pieces. Then the buttons would display the appropriate info when clicked.I understand this seems like a lot - but really I just need help getting my feet on the ground for this.

I just need a good nights sleep, but Im simply reading through a file (2010 data) and for selected teams, accessing the corresponding data for the previous year (2009 data), which is held on a separate file. (I painstakingly input all the 2009 data manually)

View 2 RepliesI had this incredibly ambitious goal to make a video game and so I am teaching myself/relying on kindness and knowledge of others as I go along. So far I have learned a lot, however needless to say, this is a monstrously difficult challenge, however one that I am very passionate about completing. The idea is that I am making a trading card style game and I was hoping that I could continue to use this thread and your kindness to keep me going whenever nessecessary throughout this challenge.So, here is where I am now. (Please forgive me if i have posted too much details/not enough details. Since I am new, I am not sure what information you need to help me. This will be corrected as time goes by and I learn more)I have created a card class with two properties. name and picture with name As String, and picture as PictureBox. the constructor looks like this: [code]
My next goal(and where I am currently stuck) is making i so that when the user clicks on one of the items in the listbox, a picture of the appropriate card(saved in a pictureBox of its own on a different form, and referenced in the card via the picture element) will be placed inside the empty picture box on the deckPage.
Im using Visual Basic 2008.Okay I got all the design, and everything set up, even the hangman body parts coming on the screen and stuff. So my problem is creating the BLANKS, the underscores "_", and replacing them with a letter...

I am having an issue getting my code to work. It is not showing my Look-Up Button for me to calculate the rate based on the weight and zone and it continues to constantly show that I have an error that I cannot seem to correct.

Student pursuing BSIT degree, employer expectations, entry level. I would like to solicit opinions from this forum as to what your professional expectations are as regards an entry level position in working in the database realm... I see many job opportunities that require a minimum of 2 or more years experience, how does one go about obtaining this experience (I have tried very hard to maintain a minimum 3.70+ GPA) but have ZERO work experience in this field... I spend non school time working in VB and SQL to try and increase my proficiency. I have considered postponing my job search until I obtain certifications from brainbench etc... Any criticism and or advise is welcomed... Again I have no experience in database other than undergrad work in class.
