When I run my program, I want my AverageInventoryTextBox to be formatted like $0.00 and my TurnOverTextBox to be 0.00 (2 decimal places)But when I do the strings for the textboxes and run the program, no matter what numbers I put in it just gives me $0.00 and 0.00, it SHOULD be like $13.84 or 7.44 something like that, but it will only give me zero for an answer.

I am having some trouble using string.Format + textBox.
Dim formatStr As String = "{0,30}{1,15}{2,15}{3,10}" Dim i As Integer txtShowAll.Text = (String.Format(formatStr, "Video Name", _ "Year Produced", "Running Time", "Rating"))

I used this code, and nothing works.I am trying to output a header, then the data under it.
My user wants to have textbox fields that don't have any masks but wants those text fields to reformat any text that is entered as mm/dd if it is a real date entered
My user wants to have textbox fields that don't have any masks but wants those text fields to reformat any text that is entered as mm/dd if it is a real date entered. They won't be using the year.
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?
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 am trying to bind a textbox to a binding source (using the IDE DataBindings Editor) and it works fine except for one thing: if I delete the text I get the subject error. What I want to happen is the datarecord field be updated to a dbnull value -- how do I get that to happen?
I need to take a string formatted like '010711' (DDMMYY) and put it into format '01-Jul-11'. Ive thought about doing something like string.toArray and then having some conditionals that format from there but am looking for an easier way.
As the title says I have a form with many databound textboxes. some of these boxes have data in them and some are empty. I need to add them altogether, so far all of the conversion methods I have tried err out when they run into an empty string, except Val, but then Val won't handle the string with a $ in it. I've tried decimal.parse which handles the $ but not the empty string. So I seem to be in circle that I can't get out of.
I have nine pictures that I need to animate -I need to use the ToString method and a counter to concatenate a file name into a string variable from the Image.FromFile method. Once the counter reaches its maximum value, and the last picture is displayed, the counter should be reset to zero or one depending on how the first image file has been name. Also a static counter variable should be incremented in the time routine. what I have so far -- I know what I have to do; however, I just do not know how to code this properly.. Right now I have this going thru a button procedure but it needs to go through a timer.
Let's say I have a page Test.aspx along with test.aspx.vb.Test.aspx.vb contains a class name "TestClass". In that class I have method1(), method2() and method3()I need to be able to call one of those methods, but I can't hard code it, the method to be executed comes from a string.
I can't do Select Case StringContainingTheNameOfTheDesiredMethod Case "Method1"
i am trying to format a numeric variable so that zeros are appended to it in VB .Net.Basically i am trying to achieve the equivalence of format(variable,"00000") in vb6, so that if variable is say 15, it can be displayed as 00015. whats the way to do it in VB .Net.
i want to dedicate a number with format method i can access to integer number with this code Dim s As Decimal = 123.326321 MsgBox(String.Format("{0:0}", s)) but now i want the floating how can i do that?
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?
So strings are reference types right? My understanding is a reference to the string in the heap is passed even when you pass the string ByVal to a method.
I'm trying to create a print function with a corresponding print preview. For some reason, any string I create with String.Format will NOT show up on the print preview! Use the code snippet below as an example:
Dim strTemp As String strTemp = String.Format("{0, 210} {1, 75} {2, 51} {3, 200} ", "NAME", "PRICE", "QUANTITY", "DESCRIPTION")
I am trying to the copy the value from string to char array using String.CopyTo() method.

I am trying to use string.format on a url to pass several values into the string. It's probably a simple error but I cannot get the following code to work. It doesn't even build the string.
