In .NET String.Format Is Accepting Objects Of A Type That Don't Match The Format String

Jul 7, 2011

I have a function that is getting passed a String and a DataRow.The String is a custom formatter. The idea is to do this

String.Format(passed_in_String, DataRow("ColumnINeed"))

The reason this is being done is at this point we have no idea what the column contains.However, if the formatter is "{0:MM/dd/yyyy}" and the DataRow("ColumnINeed") is an integer containing 42, String.Format is returning: MM/dd/yyyy In this situation I need it to throw an exception instead of returning nonsense.Is there anyway to make String.Format throw an exception if the object does not match what the format string is expecting?

Format String To Pass To String.Format That Would "move" The Decimal Point?

Aug 26, 2010

So I need a format string to pass to String.Format that would "move" the decimal point.I can't perform any math operations before doing the String.Format, so it has to work right off the bat.Basically I'm emulating a formatting string from a proprietary server. In it if I say:

"MR2"

for the value:

12345

The result is:

123.45

I'm close with this, but it's not spot on:

String.Format("{0:#0.##}", 12345)

an extra, but not necessary... there is also MR2Z, which moves the decimal 2 left, but if the value is 0 "" is returned.

VS 2008 Change Shows A Date In The Format Such As "JAN12"?

Aug 3, 2011

I've got a little program that puts some info from an sql database into some text boxes on my form.The text box i'm trying to change shows a date in the format such as "JAN12" and I just want to take off the last 2 characters (always 5 characters) and put them in a second text box.I tried this to take off those 2 characters but it doesn't seem to do anything:

Dim fixExpiry As String
Dim chars1() As Char = {"1", "2", "3", "4", "5", "6", "7", "8", "9", "0"}
fixExpiry = ST_ExpiryTextBox.Text
fixExpiry.TrimEnd(chars1)

I also tried using something like remove(3,2) but it didn't do anything either.

Asp.net - Decimal.parse Fails For Currency String Created With String.Format?

Apr 5, 2011

I have a field that I display via: String.Format({0:c},amount) This produces the string "$28.28" However, when I try to convert back to a decimal amount, I get an incorrect format exception: amount = Decimal.Parse(amount.Text, NumberStyles.Currency) I also tried it with NumberStyles.AllowCurrencySymbol with the same results. I verified that the value in amount.Text is "$28.28". Am I missing something? Shouldn't these two operations use the same currency symbol and formats?

Specify The Decimal Rounded To?

Apr 1, 2009

I'm working on a calculator application and one function is to find midpoints on a cartesian coordinate system. I have inputs for two x and two y coordinates , and the program calculates the midpoints of both and prints them in a text box as a new set of coordinates. The points are represented by doubles to allow decimal and negative points, but I want to round the final coordinates to 1 decimal place. e.g: (12.5, 9.8) Math.Round would work, except that it only seems to be able to round to a whole number. e.g: (12, 10)

Is there any way to specify how many decimal places Math.Round rounds to, or is there another function that could acheive this result?

GDI+Rendering Rounded Rectangle?

Feb 16, 2011

Working on some UI stuff, but I am having a problem drawing 'Top rounded' rectangles when the two top corners are rounded. I have methods to draw all four corners rounded and bottom rounded rectangles and they render fine.

I have attempted the graphics methods in CreateTopRoundedRect() in a variety of different orders, drawing the other corner first, the bottom line first, the bottom line before the left line, etc. In this function you can see a diagonal line splitting the shape. If you were to switch the bottom and left lines only half of the shape would be filled.

Prevent Integers From Being Rounded?

Feb 15, 2011

I have two textboxes that will contain numbers.I convert those text boxes to integers and then want to multiply them by certain values and then show the new value in a different textbox.For example,100 gets converted to an integer and then multiplied by 1.75 and the value displayed in the other textbox is 200 instead of 175.How do I make it so the value isn't rounded to the nearest 100? Here is my code, compTotalPremium.Text and collTotalPremium.text are the boxes that are showing the rounded value.

Dim Comp As Integer = compDedPremium.Text
Dim Coll As Integer = collDedPremium.Text
Dim CompMulti As Integer = compDedMulti.Text[code]....

Rounded Rectangle Not Accurate?

May 19, 2011

Every sample code I've ever found for drawing rounded rectangles using GDI+ goes something like this (lifted and slightly modified from BobPowell.net):

Private Sub Panel1_Paint(ByVal sender As Object, ByVal e As PaintEventArgs) Handles Panel1.Paint
e.Graphics.Clear(SystemColors.Window)
e.Graphics.SmoothingMode = SmoothingMode.None

[code]....

This produces a rounded rectangle where only the top left corner is accurate.AntiAliasing has to be turned off because it is going through a remote desktop connection, and I can't depend on it being available. Besides, I am looking for a crisp rounded rectangle.I've tried resizing the other corners and changing the pen alignments, but nothing seems to produce a simple, accurate rounded rectangle.Is there a way to draw a better rounded rectangle than this in good old winforms?

Making Rounded Ends On Lines?

I need some help importing data from Excel 2003 into VB10. My goal is to import the data and save it to a 2D array for later use within the application. The data is on sheet 1 of the workbook and goes from A1 to D1072 with a header row. I have done a lot of research on line to find a solution but have been unsuccessful. From what I have found I have put the following code together. When I complile and run the program I get the following errors.

1) I think while compiling it gives me this error: The source file is different from when the module was built.

2) While running the program it stops on the connect.Open() and has this error OleDbException not handled. Could not find installable ISAM.

Two Decimal Point Rounded To Nearest 20

Aug 20, 2010

I have read about Round() and MidpointRounding.ToEven but I still could not figure how to use it to achieve what I want. I have numbers (usually from 5 digit decimal) such 125.36 , 125.10, 125.99. I want to make the 2 decimal point rounded to the nearest 20. Means, the 2 decimal point should be either .00 or .20 or 0.40 or .60 or 0.80 only.
125.36 should be 125.40 : 125.10 should be 125.00, 125.99 should be 126.00
125.54 should be 125.60 and so on
Is there math function to make or I should parse the number as text and test the last 2 digit?
