.net - How to print a multi-lined string into a message box? -


i trying print 'last receipt' customer in have stored sting variable called prevrecpt.

i want able press button (btnlastreceipt) , display sting in message box.

is possible? have tried , ended message box showing first line? 

        prevrcpt = "--------------------butlers cinemas--------------------" &     environment.newline         prevrcpt = prevrcpt & tbtime.text & environment.newline         prevrcpt = prevrcpt + "operator: " + tbuser.text & environment.newline         prevrcpt = prevrcpt + environment.newline & environment.newline + "-------------------------------------------------------"         prevrcpt = prevrcpt + "total spent: £" + tbtotal.text + environment.newline + environment.newline         prevrcpt = prevrcpt + shoppingcart.text + environment.newline         prevrcpt = "--------------------butlers cinemas--------------------" & environment.newline

this code building string.

have tried concatenating environment.newline anywhere in string?

now can see code, seems last line should instead:

prevrcpt = prevrcpt & "--------------------butlers cinemas--------------------" & environment.newline

that being said, need aware in event of long string, message box size out of screen bounds, may want use else messagebox. if possible, make own dialog form, make default size convenient scenarios , use scrollable text zone within it. readonly textbox multiline property set true not scrollable, also allow end user copy content in clipboard. may make user's experience lot better.

i should mention stringbuilder class , few constants make code lot cleaner:

const headerorfooter string = "--------------------butlers cinemas--------------------" const separator string = "-------------------------------------------------------"  dim b new text.stringbuilder()  b.appendline(headerorfooter) b.appendline(tbtime.text) b.appendformat("operator: {0}", tbuser.text) b.appendline() b.appendline() b.appendline() b.appendline(separator) b.appendformat("total spent: £{0}", tbtotal.text) b.appendline() b.appendline(shoppingcart.text) b.appendline(headerorfooter)  prevrcpt = b.tostring()
