Get Me From Beginner To Intermediate?
Jul 22, 2010
I want to learn visual basic, what book or books are the best to take me from beginner to intermediate?Would it be more advantageous to go through VB 2008 or VB2010 tutorials first or should i start with a book before going through VB2008 or VB2010 tutorials?I am comfortable with Sequel (SQL) language, learned on the job and am at the advanced level of Excel/Access writing formulas functions,etc. the next logical step is to learn VB.

I have a few SQL connected check boxes in my form.The problem is that on the 'Add New' event the check boxes go into a "intermediate" status (filled in).What I would like is for all the check boxes to be unchecked.I have so far tried the following and none of it worked.[code]Nothing seems to help, in fact there seems to be no effect at all on the check box properties no matter what I do (wether I change the property in VB, in the table definition, or programicaly).

Running through some basic tutorials and wanted the test the value of a variable i have created. How do I go about doing this in the intermediate window??
The only way I can do this is by creating a msgbox and then outputing the string var in the msgbox (var) to get the value I am after. Is there a way of doing this in the intermediate window??
I tried the following. but had no luck...
? ckstatevar
My code is as follows:
Private Sub ckboxDexter_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ckboxDexter.CheckedChanged
Dim ckstatevar As Single = ckboxDexter.CheckState
[Code].....

I have a DataGridView that has columns with a value type of boolean.To load the DataGridView, I load values into a DataTable then set theDataGridView.DataSource = theTable What value can I use in the table to load an intermediate check state?
Would it be better to use a check box control with a value than to use a column set to the boolean data type?
The check box is for display only, and will not need to be changed.

from the vb web:
Quote:
The following Microsoft intermediate (MSIL) instructions throw OutOfMemoryException :
*
box
*
newarr
*
newobj
Does anyone knows what exactly does box means? and also is there anyway this statement will cause an outofmemory: Dim a As Boolean
What about if its just an empty object: Dim a As someobj

In need of some desperate help. Has anyone had any experience with a software product called Pres? The programme provides a function (userhook) that can run externally created dll's as the programme offers no COM support. The basic requirements for the dll are as follow.
1, The dll requires a public function named UserInstruction
2, The UserInstruction must have 5 parameters. The first and second of type long, the third a double array and the fourth and fifth parameters required type is a string.
This all seems pretty simple. But as .NET doesnt support exporting functions within a DLL to allow direct public access to the function through third party software it becomes tricky. After doing some research it seems as though this isn't possible in .NET. The only way I can see to do this is to convert the dll to Intermediate Language and play around with it once this is converted and then convert the IL code back to a DLL. I found this on the following site [URL]..After trying this when I try to use the DLL via Pres I am still getting no joy.

I'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)
ds1.Clear()
cmd1.CommandText = "SELECT * FROM Teams WHERE Team = ?"
cmd1.Parameters.Add(NewSqlCeParameter("Team", (ds.Tables(0).Rows(x) ("Team"))))
cmd1.Prepare()
cmd1.ExecuteNonQuery()

I 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 was thinking creating Lables which i have no idea how to dynamically. Then giving each label name the letters they belong to, and everytime the user gets the rigth letter they get replaced.

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.

I am trying to create a program that the user enters the number of enrollments for 5 different campuses during two semesters. I just got started and here is what I have so far but when I run the program it is stuck in an infinite loop and will not go to the next function. I am not sure how to end the loop. Here is what I have so far:
Module Module1
Dim SIZE As Integer = 5
Dim campus() As String = {"Decatur Day", "Decatur Evening", "Huntsville Day", "Huntsville Evening", "Distance Learning"}
Dim semester() As String = {"Fall 2010 semester", "Spring 2011 semester"}

I am just for learning purposes trying to develop a one player text based game.
I have a rich text box (GameWindow)
I have a text box (InputWindow)
I have a button (InputButton)
and a bunch of labels that aren't really important
I have two questions first is easy probably. How do i get InputWindow to respond to me hitting enter when text is in it?
[Code]...
But if i plan to have more that is only going to increase the size and code needed and im sure there is an easier way i just don't know how to do it.
