Upgrade From Quick Basic On XP?
Nov 12, 2009
I used to write programs in Quick Basic on my XP computer. I now have a Vista (64bit) computer and everybody knows (except me) that those programs won't run on my Vista computer.I want to be able to write single user programs on my Vista computer like I did with my XP computer. Since I'm somewhat familiar with the Quick Basic language, I want to stay in the "Basic" language family. What do I need to have on my Vista computer that would allow me to write and run simple single user programs?

I'm trying to convert an old Quick BASIC program to VB.Net. There doesn't appear to be any direct replacement for the old file statements. Building a database seems like overkill for my simple needs.
How can I do the following in VB.Net?
OPEN "test.dat" FOR RANDOM AS #1 LEN = 20
FIELD #1, 10 AS a$, 10 AS b$
LSET a$ = "One"
LSET b$ = "Two"
PUT #1, 1
GET #1, 1
PRINT a$, b$
CLOSE #1

I have a Visual Basic 6 program that I would like to update to Visual Basic .NET I am running Windows 7 Professional and have downloaded and installed Microsoft Visual Basic 2008 Express Edition. The problem I have encountered is that when I open my VB6 project file (.vbp) the Upgrade Wizard does not open. Instead, a list of references, objects and forms from my project appear. Is there any other way to run the wizard? Or am I missing something?

I am developing a VB application using the Visual Studio 2008 IDE. I was making changes to my code using the Quick Replace function when the dialog window stopped displaying. Selection of Quick Find or Quick Replace from the Edit menu, as well as use of shortcut keys (CTL+F and CTL+H) all have the same affect: the IDE loses focus but no dialog windows display. Is this a known issue with an available fix?

I have a RichTextBox where I expect 100 characters per line. Each line can start with the letter A, B, or C. I may have thousands of lines and most of them will start with the letter C.When the cursor is moved from one line to another and is placed on a "C" line, I need to be able to quickly locate the nearest "B" line above it. It may be hundreds of lines away. A loop to search for the "B" line using GetFirstCharIndexFromLine(x) is too slow.
The user may want to paste many lines into the textbox. If necessary, a mild wait after pasting is acceptable.Do you have any suggestions for a technique to accomplish what I need to do? Even just a high level suggestion like "use a linked list"

I have a list with a boolean value as one of the properties. I need to check if every one of these is true. Now normally LINQ would give a nice clean answer here, but as I am using .NET 2.0 I can't use that.If there a nicer way to do this or am I going to have to do a for each loop and break out on finding a false?
Edit:Seems I could have been a bit clearer. I have an object in a list (eg List (Of MyObject)). There is a boolean property on this object called Processed.I need to check that all objects in the list are processed.So in LINQ I'd do:if (from o in list where o.processed = false select o).count = 0 then....

As a measure of emergency I need to prepare a very simple ActiveX object to be used in Excel sheet and VBA.I'm not a hardcore programmer myself but I'm able to put together a code in VBA to get things done. I have no experience compiling ActiveX dll's in VB though.Could anyone point me to a simple tutorial on the web where I could learn steps how to do it in VB? (project type, setting up methods for the control, parameters for compiling the dll so it's recognized as an ActiveX.. etc)The ActiveX object will be very simple - it's a stopwatch:
1. displaying elapsing time, I have it done already in VB as a windows ap.
2. As an object it will be taking only 3 types of methods: start, stop, reset
3. it has to be a proper ActiveX, so I can use "insert ActiveX" in Excel to add it to the sheet and the code.
I guess I have to start with creating a 'class library' project, haven't I ?

I am wondering how can I show a balloon tip for my system tray NotifyIcon application QUICKLY. What I mean by quickly is not linger around for like 5 seconds.. I have tried entering 1. For example my code is currently:
NotifyIcon1.ShowBalloonTip(1)
I thought about trying decimals but if I remember correctly from C++ it does nto work or make a difference.. how to display a balloon tip that pops up for only 1 second then dissapears very fast?

If I have a class with a couple of event handlers inside of it which are attached to an object that is defined within the class, am I right in thinking that I don't need to implement IDisposable to remove said handlers, even if I explicitly added the handlers myself? Also, can anyone point me in the direction of an article that explains the scope of when it is needed to remove handlers to avoid memory leaks. (I've tried searching many times but I must be screwing up my search terms.)I have a collection; every time an object is added to that collection, I add a handler to a change event of the object.When I'm done with the collection, do I need to go through each item and remove the handler before setting the reference to null?

Okay, I've been at this ALL DAY no one's advice has helped so I'm zipping up the simplest version of my problem and attaching it a silver dollar for anyone who wants a quick and (seemingly) easy problem. What it is:
frm1 loads with a button to start frm2(and populate a datagridview).I'm trying to save its data in the module in the example but it might not be necessary.Then another button closes/hides form2 and you can push a button on form 1 to TRY TO get the frm2.datagridview1.item(0,0).value.I can't do any more tonight.

I am rather familiar with the ins and outs of VB.NET and Database Selects, Updates and Inserts. Not so good with Transactions. (Oracle, MSSQL)
for example, take a Billing System for a hardware store.I create a 'New Order' and select the Cash Customer I start adding items to this order. 1 Rake 1 Shovel Where do I store this information (temporarily) until the user hits 'SAVE'. Maybe the customer decides they don't want the items. Too expensive. I just EXIT. nothign to do.
Or - I open an existing order and make a bunch of changes. Where do I put these changes until the user hits SAVE. I am sure transactions might have something to do with this - or temporary somethings??? I just don't know and need some guidance.

I have a table that has 9 columns, this table has about 5000 rows, but sometimes the user need to update the data in the table. The new data is in another table, with different columns names and only with 8 columns, the ninth column it's the date of the update (i know that this columns shouldn't be here...).
So for now i'm filing one datatable (the data come form a webservice that returns a dataset with this table), and after that i clean the original table and then for each row in the new datatable i call the insert command.Is there other way, better way, to do this?

I'm trying to put together a quick program for our database, I haven't touched VB since vb6, and we have 2008 .NET now. my question.
Ideally I'd like to make an array which can hold multiple values...such as
Job[job#].joblocation
Job[job#].jobsupervisor
So there would be a Job array, and then different values contained within that. I can't seem to make an object or whatever which allows me to hold different variables inside it.

I am developing an application that prompts an user for doing certain tasks in a form. What i want is that a certain message should be popped for a certain amount of time and then close (probably say 2 seconds or so). I tried doing it with message boxes but they do not close on their own as they are designed to be modal (to wait for user command ). i do not want to display the text in a textbox of listbox. Is there a certain way i could do this.

I know this is a VB.Net messageboard, but it can work with in all languages. Is there a quick way to complete a line (sample code):
//Setting variables set 1
a = e;
b = f;
c = g;
d = h;
.....
//Saving changes set 2
e = a;
f = b;
g = c;
h = d;
without having to type everything out...A technique using EXCEL or Notepad....Find and Replace. This would save a lot of time coding and becomes pain in the butt when you working with many variables.

if there is a quick way of creating a new blank bitmap say 1680x1050 - just wondering cause i want to make a live animation that is this big ... but when looping this it is fairly slow while doing this...I have tried:
New method:
Dim B as new bitmap(1680,1050)
Create once then clone:
Static NewB as new bitmap(1680,1050)
Dim B as bitmap = NewB.Clone[code]....
All of the above are about as slow as each other...

Private Sub Bearing_Textbox_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Bearing_Textbox.KeyDown
If e.KeyCode = Keys.Enter Then
e.SuppressKeyPress = True
Call Plot()
[Code] .....
Which is used to plot bearings. The user inputs a bearing of 0-360 degrees. It works fine if a user say types in "abc" or "/" i.e. anything that isn't numeric. But if a user types in "90/" then it allows it. When the bearing is plotted the keypress is surpressed so the user cant then go back an edit. Is there a quick way to amend the code to allow for this?

Just trying to make a form which is 15,13 (small I know!).When I set the form size it accepts it but when building it bumps the form size back up to a larger value.The reason this is required is irrelevant, just wondering if there is a minimum size a form can be set to and if there is, is there a work around?
