I'm using Visual Basic .Net 2010 Express.I know, for example, that the Visual Basic ( IEEE 754 ) Internal bit-by-bit Double Format is: Bit 63 = Sign, Bits 62-52 = 11-bit Exponent, and Bits 51-0 = 52-bit Fractional Significand.But, I can't seem to find any documentation on the Internal bit-by-bit Decimal Format.There also don't seem to be any workable mechanisms for accessing the bit structure or copying the bits to another Format for internal processing and returning the result to the Decimal Format.[code]to separate the ULongVariable into bytes for convenient manipulation. A similar reverse process allows moving the manipulated bits back into the Signed Long Variable.But, methods like << and >> are not extendable to Decimals per the Microsoft Documentation ( and I tried them anyway, and confirmed that they don't work ). Nor does there appear to be any way to copy the 128-bit Decimal into two 64-bit Unsigned Long Variables, or vice-versa.
I could, of course, forgo the use of Decimals and define my own MDJDecimal consisting of two ULongs, but that seems a bit of an overkill, and its methods would likely incur significant development time, and would probably also be rather excessively slow and cumbersome.I know I could write a workable routine in Visual C++ .Net using the Unmanaged Native Assembler, but I don't know enough about how to integrate that with Visual Basic .Net code, and I don't want to irrevocably tie what I'm developing to the Intel platform.I might also be able to write it in Managed Visual C++ .Net, but, again, I don't know enough about how to integrate that with Visual Basic .Net.
Is it possible to have an internal XML dataset within a VB 08 program I ask because we at present have the program load an external XML on startup, but i would prefer this to be internal withing the program to stop other editing the XML file.
I have an internal process that requires data in a very specific format. Nothing I can do about that. So in my VB.NET program I am trying to output a number with a terminating decimal and nothing after it. I tried
I'm trying to get my decimals to display with four decimal places. The DB rounds my number to 4 decimal places, but it returns the number with trailing 0s (due to the decimal precision of the field), so something like 9.45670000.[code]...
How do I format my decimal, so that the number of decimal places is always four?
format a decimal value to a string with a single digit after the comma/dot and leading spaces for values less than 100?For example, a decimal value of 12.3456 should be output as " 12.3" with single leading space. 10.011 would be " 10.0". 123.123 is "123.1" I'm looking for a solution, that works with standard/custom string formatting, i.e.
decimal value = 12.345456; Console.Write("{0:magic}", value); // 'magic' would be a fancy pattern.
I have a simple text box and I am entering number value to this.And i want to format the number value to two decimal places.Like If i enter the 10 in the text box and after pressing entering or leaving textbox it should be converted into 10.00.Please tell me if there exist any possibility to do this using javascript or vb.net or asp.net property of textbox.I already tried in JavaScript on enter key or tab key press but it convert it into 10.00 each time when i press the enter or tab.here is code
//Make Formatting with .00 document.onkeydown = function disableKeys() { if( typeof event != 'undefined' ) {
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.
I want to format textbox to decimal : I use this code in button1.click , it worked : TextBox1.Text = Format(CType(TextBox1.Text, Decimal), "##,###.###") But each time button1.click and textbox is formatted will bring a unexpected error for me. I want in form.load event. I format textbox. I tried above code but it is error.
Is there a format string to format a decimal to 000000000,00. So first 9 digits, right padded with zeros if needed; a comma as fraction separator and two fraction digits. 0 => 00000000,00 12 => 00000012,00 987456,456 => 000987456,46 So something like myDecimal.ToString("D9") together with .ToString("F2").
I realize the code listed below, whose serial port using string formatting which I inherited is complicated. It formats a Date obtained from a DatePicker control into a "yyyy-MM-dd HH:mm:ss" string format to send to a hardware device to be stored via Serial Port retrieves the date from the device and displays to user What I'm trying to do is port the code for use in a Socket rather than Serial Port which wants a Byte Arrray of the same Date Time string variable. I can't figure out how to encode and convert to Bytes the string value used in the Serial Port version. The evolution of the process is listed from top to bottom.
I have managed to format a text box to be formatted to two decimal places, and to only accept numbers.Only problem is i need to allow the backspace so that if someone types something wrong, they can backspace and type the correct number
Private Sub txtCAmount_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtCAmount.KeyPress 'Allow only numberical input plus decimal. Dim allowedChars As String = "0123456789."
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?
