Build A Scientific Calculator With Vb?
Aug 11, 2009I'm trying to build a scientific calculator with vb .net, except it is vista glass :-p
I basically want the user to be able to enter an equation like SQRT(5 * 6) / (2 ^ 4) and then I want vb to use system.math to solve it. If I write this in my code, vb is able to do it, so how could I do this at runtime.

Interfacing With Windows Calculator In Scientific Mode
Aug 29, 2009Introduction: Probably a year or more ago I asked if was possible to use the Mathematical functions in Windows Calculator or use any DLL file it may use without a satisfactory answer. As I require the greater accuracy of Windows Calculator in String format. Would it be easy to keep switching between a Vb.Net Form windows based application and Windows Calculator and, using SendKeys, get results back to a Vb.Net application using Copy & Paste via the clipboard but to do this in an automatic fashion at all please?
What I am particularly interested in is getting Log10 or LogN results and also doing ARC or INVerse LOG10 or INVerse LogN calculations. But I require the greater accuracy of windows Calculator. Additionally, would it be possible to assign a keyboard keymap to each key in Windows Calculator so that, for example, the L key would be assigned to clicking the LOG10 button, ALT for the Hyp checkbox, SHIFT for the INV checkbox and so on?So imagine sending key sequences to Windows Calculator to completely automate it. And Windows Calculator has been updated too in WINDOWS 7, would that make it any easier to work with?

Scientific Calculator - Clear Textbox After Displaying Result
Jun 2, 2009I am building a scientific calculator.
1. After I clicked the Sine button, I get the result in a textbox.. When the result is there, for example: 1 radians Sine = 0.8414.... I can still put numbers at the end of this result.. like button 5 will be 0.84145, so how can I disable that?
2. After I get the result from a calculation, the textbox should be cleared when I insert a new number.
C# - Produce A PDF Report From Code In .NET For Scientific Data (winforms)?
Mar 13, 2011I have a "legacy" VB.NET application (winforms) written for .NET 1.1, and re-compiled under 2.0 that produces a report in HTML via a custom XmlTextWriter wrapper that is suited for HTML. The user then would print the report into pdf if they wanted to.
That was 2003, and now technology has changed a bit, especially within the C#/VB.NET world, and customers want to skip the HTML part, and go to PDF directly. What are my options for open source, or low cost PDF libraries that work well with .NET and must support tables with pictures (generated bitmaps from code) and text.

Loan Calculator Code Using Scrollbars
Mar 22, 2009I wrote a Visual Basic program using the PMT function to calculate the monthly payment for a loan. Also calculate the Total of All Payments made over the term of the loan. This is how it should work, The user will input the loan amount in a text box. The user will use horizontal scroll bars to input the term of the loan (years), and the rate of the loan. As the user clicks the scroll arrows for years and rate their values display on the form above each scroll bar. When the user clicks the Calculate button the program will output values for the amount of the monthly payment and the total of all payments for the term of the loan. The two scroll bars are set to their mid-points (15 years and 10%), I am unable to get to show this values in their respective text boxes for some reason. [Code]

Write Double In Non-scientific Form?
Sep 18, 2009I would like to know if Visual Studio does have a setting where you can choose whether it should write nombers like 0.00000127 in scientific notation or not? I am writing such doubles to file but VB2008 writes them in scientific notation. If I treat these numbers as decimals then it writes them correctly, but I also have to take care of performance as I'm writing lots of numbers.
View 1 RepliesConverting Double To String (Not In Scientific Notation)
Nov 12, 2011The only post I can find on this matter is one that coverts the double to a decimal before converting it into a string. However the numbers I'm using are far larger than what a decimal can store.
Example: 1/(16^10)
So how can I convert the solution to the problem above. Which equals 0.00000000000090949470177292824, to a string value that is exactly as it's shown?
Cause when I convert this to a decimal I still end up with a string in scientific notation..

EXCEL Reads A Text String As Scientific Notation
Dec 31, 2007I am working on a project that involes reading an Excel file, picking through it, then creating a flat CSV file. One of the the data elements I am picking up is a 9 character string that may be numeric, or contain one or more alpha chatacters. Excel has a nasty habit of converting long numerics to scientific notaion. I can overcome this by converting the "general" string to "TEXT".
However, there is one instance where I can not get the function to work...the string is "90333E108" ( the CUSIP for USU). Regardless, the text string is saved properly into the CSV file. When opened in a text editor, it reads correctly.
When opened with Excel, it is in scientific notation. Changing the field to "text" from "scientific" still displays "9.03E+112".
how to create an csv file that Excel will open and read correctly?
You can test this by creating an Excel workbook, format all cells as TEXT and add the following data:
90333E108
