I am outputting a columnar table to a text file, 5 columns each 20 characters wide.he example below lets me align these columns either left or right.
Dim strfmt As String = "{0,-20}{1,-20}{2,-20}{3,-20}{4,-20}"
Dim strfmt As String = "{0,20}{1,20}{2,20}{3,20}{4,20}"

var queryString = string.Format("filename={0}&filestream={1}&append={2)", fileName, Convert.ToBase64String(b, 0, bytesRead).ToString(), 1);
above line of code giving error 'Input string was not in a correct format.'
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?
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.
however, i'm copying this directly from the book in its example format and still getting an error.

How to format by padding left and right. I have two integers, two strings, and another integer that I need to align neatly in columns. There is a total of about 100 columns, and they have to be neatly aligned.
Here is my code:
Console.Writeline(num1.ToString().PadRight(5) + num2.ToString().PadRight(5) + str1.PadLeft(20) + str2.PadLeft(20) + num3.ToString().PadRight(5))
How do I pad it correctly so the columns can be neat and aligned.
I want to format the Timespan to have format like this 49 hr 34 mn 20 sec
I used the String format below :
String.Format("{0:00}:{1:00}:{2:00}", theTimeSpan.TotalHours, theTimeSpan.Minutes, theTimeSpan.Seconds)
It formats the Timespan to this format 49:34:20. How can I add hr mn sec to the String.Format above? or there's another easy way?
I am using String.Format("{0:C2}", -1234)to format numbers.is always formats the amount to a positive number, while I want it to become $*-*1234
View 4 RepliesI 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?

I was writing an application that draws a bunch of random lines on a form with the mouse move event. I set the windows start position property of the form to center screen, but no matter what I did the form would appear in the windows default position. After around 30 minutes of cutting code and trying to paste it into new projects, it still wouldn't center the form. I finally gave up trying to center the form by setting the form property, so I changed it to manual and wrote code that centered the form horizontally, and around 50 pixels from the top edge and the code worked. Has any one else had this experience with VS 2005 proffesional?It was really bugging me for some reason.

How I have centering Form2 inside Form1. CenterToParent() doesn't work.
View 14 RepliesI am trying to make my first program in vb.net 2010, and I have a question.ou know how when you have a button, the text centers itself within the frame of the button?I have a label in my application, that displays a different text (through the label) everyday.
View 1 RepliesFor example I have Form 1 with 1 button, if I press that button a small form will pop out (This form is smaller than form 1, lets call it form 2). My problem is I want that if I press the button in form 1 it will show form 2 then adjusting the size of it and centering it.
I coded the Form 1 that it will send a string Extra_Background_Form.Label1.Text = "a" to form 2 then it will load form 2
totality of code in form 1:
Extra_Background_Form.Label1.Text = "a"
Extra_Background_Form.Show()

Is there a way to enable a default pan behavior in the .Net scrollable control when you press down on the center scroll button, or Is that a behavior you have to implement yourself? You know like in some programs where you press down on the center button and it give you an arrow cursor that pans whichever direction you move the mouse?
View 1 RepliesBasically, I have a program that uses up one Monitor (With maximize/minimize/etc options), and I'm going to develop another window that by default, you'll have to swap to. But, if there are two or more monitors detected, throw the 2nd form on the 2nd monitor.
I have found a way to detect multiple monitors (Using the SystemInformation Class to return the monitor count), but it's placing the form on the other monitor that's the problem.
I have a project that calls for just a ton of forms and I'd like them all centered on screen. Any way to call this in a module? Just trying to minimize the code necessary for each form. This is the basic centering I use now, only it's in each form_load.

Dim xLoc As Integer = (Screen.PrimaryScreen.Bounds.Width - Me.Width) 2

Me.Location = New Point(xLoc, yLoc)

I created a custom control and I'm trying to insert it into a panel, but also center it.The control itself is larger than the panel, so I've set the AutoScroll property of the panel to True. I think that might be affecting it. Perhaps I should just offset the Y axis a bit.But, either way, this is what I'm trying:
VB .NET
'Create the control
Dim AutomationReport As New AutomationReportControl

It works just fine with the X axis, but the control is out of bounds vertically. About 1-2 inches of the top is cut off.
