VS 2008 Files In The Right Places?
Apr 23, 2009
very very inexperienced programmer here. just trying a practice program and it downloaded 4 Vb files;FRX file, VBP File, VBW File and FRM File.
i've gathered VBP is the project and FRM is the form and put them in the right places (i think) from what ive read from this thread[URL]...FRX and VBW locations? also it was originally created with Vb5 or Vb6 but will it work with my VB2008?

Problem: Using the sub routing below, when adding a value to another value the results eventually change from 2-decimal places to multiple decimal places.Basically, the amount stored should always only be 2 decimal places, because the values passed in are always 2 decimal places. Output from calling the sub routine multiple times.
Running total = 329430.75
New Withheld Amount = 710.79
Running total = 330141.54
[code]....
As a workaround, I have a new routine that uses a custom round function to properly store only 2 decimal places - as the VB round function does not perform the type of rounding desired.I understand that we are removing the value from the dictionary and adding it back..

I have constructed my program. I had my price variable originally set to integer, but I found this was causing me errors as the numbers were just being rounded to the nearest 10 and not the exact decimal place.
I have since changed the variable to a decimal and now see this in the errors box, how do I elminate this error?"A first chance exception of type 'System.ComponentModel.Win32Exception' occurred in System.dll"
Secondly, it is producing the correct price but only to one decimal place. How do I get it so it displays the price to two decimal places?

How do I round my values to 2 decimal places in a datagridview.
I have a value column that is picked up from a SQL Server datafield type Money. In the database this sits as I want it to appear in the datagrid with 2 decimal places. In the datagridview it shows with 4 decimal places.

I have a form with a textbox on it. Validation occurs on the leave event. If validation fails, the focus is set into the textbox, making it impossible to click outside it unless there is a valid value entered. A valid value is anything from 15.00 to 99.99 inclusive, always with two decimal places.What code will return a boolean answer that checks if the input is valid?

the first is validating numeric input in a textbox to make sure it's got two decimal places. I think this should be really simple, but I'm totally missing it.The second is adding an extra summary line to a listview. I have it working with all the data required, but I need to add an extra line at the end showing some totals. How do I do this?

Having a slight permission problem with Win 7 I am guessing it will be the same on Vista but work fine on XP (yet to try)But my program is sitting in: C:Program FilesCompanyProgram And its trying to create new files alongside itself in the Program Files area but bombing out which I know is permissions. If I go there to create the file myself it comes up with a UAC prompt and when I hit allow it works fine but obv the program can't do that byiteslf so bombs out.Is there anyway I can over come that without the user having to grant admin rights to the program each time it starts or do I have to write data to another place?

I recently upgraded my PC and software from XP 32-bit to Windows 7 64-bit. I'm using VS 2008 and SQL Server 2008, and I write code in VB.Net. I'm interested in compiling my code in 64-ibt. Under Visual Studio, I see three different places to specify which CPU to compile under: 1. In Solution Explorer, click 'My Project', then Compile->Advanced Compile Options->Target CPU.
2. On VS menu, Build->Configuration Manager->Active solution platform.
3. If #2 is set to x64, then in Solution Explorer, click 'My Project'->Compile, and at the top, Platform (if #2 is not set, the only option available here is Any CPU).

Using Visual Studio I'm using TextRange processing a word at a time, parsing for figures and minus values etc. All of which works. However I have to honour the original number of decimal places in the figures, even though they may be 0's.ie -1219.0 and 1219.00 are both valid inputs the valid outputs would be(1,219.0) and 1,219.00, I can't just use tostring and stamp all of them as "N2" etc).I have to format including retaining the trailing 0 if necessary.I can use "#,##0.######" but that removes trailing 0's... ie both above example would be changed to 1,219 pos or neg.

I used math.round(decimal, 2) in the hope that it would give me two decimal places.
But when the last digit is 0 VB 2008 doesn't display it. I get "1.3" instead of "1.30"
How do I force it to give me 2 decimal places in the rounding from the decimal?

My computing teacher challenged me to write a console program in Visual Basic.NET which would calculate π, AKA Pi, to 14 decimal places. I contemplated various algorithms, then settled for a variant of Leibniz's series which would converge rapidly whilst being simple to implement.After about 30 minutes or so of programming I had finished my program which could generate the first 14 decimal places of π in a mere 27 iterations, below is the source code:
[Code]...
However, to my dismay, I soon discovered that this was all my program was capable of because of the IEEE specifications for numbers, although I've heard of people generating π to thousands of decimal places using unmodified Personal Computers so if you could tell me how I should modify my code to work around this to generate say 500 more decimal places.

This actually seems to make it miss calculate, so I've put it back to Pweight.ToString() and left it at that but I get around 12 decimal places.

I have designed a unit converter that converts between different units. The value and unit to be converted from are entered in the first text box, for example "1 km" and the unit to be converted to is entered in the second text box. Then after pressing the calculate button, the new value will be displayed in the second text box as the output. By default the output will be specified to two decimal places. However, if the input has any number of decimal places, for example "1.045 km" the output should be displayed to the same decimal place, in this case 3.Displaying the output to two decimal places was easy enough to figure out, I just used:
FormatNumber(finalValue, 2)
But I'm completely stuck on the other part however and I'm wondering if anyone here has any suggestions. I thought about doing something like this:

how you can get the places bar-style interface in an OpenFileDialog window? So far (from what I've read) it appears that OFDs in XP have it by default, but in Vista and 7 they don't. So how can I get that OpenFileDialog interface backin Windows Vista/7? Or am I just mistaken and it's not a XP/Vista/7 problem at all and I'm missing a point?
