i have a string...in which i am passing a value just like that:
dim strHeader as string
strHeader &= ".header {" & vbCrLf & _
"background-color:" & bgColor & vbCrLf & _
"color:" & foreColor & vbCrLf & _
"font-family:" & fontName & vbCrLf & _
"font-Size:" & fontSize & vbCrLf & _
"font-weight:" & fontType & vbCrLf & _
"height:" & height & vbCrLf & _
"}" & vbCrLf & vbCrLf
but warning occured that is
variable strHeader is used before it has been assigned a value a null reference exception could result at run time...
is there any way to remove this warning.

you should initialise it first.

Just replace the '&=' in the second line with '='

Otherwise it doesn't know what to concatenate to.
