hello
iam working on asp.net1.1 & make this function for generating the image conmtaining the alphanumeric characters but my problem is sir iam returning the bitmapo image to show on the webpage but iam unasble to show on the web page so please help me to suggest me the code to show the returning bitmap image beloww i can send u function



Public Shared Function RandomString(ByVal iLength As Integer) As String
        Dim iZero, iNine, iA, iZ, iCount, iRandNum As Integer
        Dim sRandomString As String ' we'll need random characters, so a Random object ' should probably be created...
        Dim rRandom As New Random(System.DateTime.Now.Millisecond) ' convert characters into their integer equivalents (their ASCII values)
        iZero = Asc("0")
        iNine = Asc("9")
        iA = Asc("A")
        iZ = Asc("Z") ' initialize our return string for use in the following loop
        sRandomString = ""
        ' now we loop as many times as is necessary to build the string ' length we want
        While (iCount < iLength) ' we fetch a random number between our high and low values
            iRandNum = rRandom.Next(iZero, iZ) ' here's the cool part: we inspect the value of the random number, ' and if it matches one of the legal values that we've decided upon, ' we convert the number to a character and add it to our string
            If (((iRandNum >= iZero) And (iRandNum <= iNine) Or (iRandNum >= iA) And (iRandNum <= iZ))) Then
                sRandomString = sRandomString + Chr(iRandNum)
                iCount = iCount + 1
            End If
        End While ' finally, our random character string should be built, so we return it
        RandomString = sRandomString

    End Function
    Public Function generateImage(ByVal sTextToImg As String)
        '//
        ' //Here, i haven't used any try..catch

        Dim pxImagePattern As PixelFormat = PixelFormat.Format32bppArgb
        Dim bmpImage As Bitmap = New Bitmap(3, 3, pxImagePattern)
        Dim fntImageFont As Font = New Font("Trebuchets", 14)
        Dim gdImageGrp As Graphics = Graphics.FromImage(bmpImage)
        Dim iWidth As Integer = gdImageGrp.MeasureString(sTextToImg, fntImageFont).Width
        Dim iHeight As Integer = gdImageGrp.MeasureString(sTextToImg, fntImageFont).Height
        bmpImage = New Bitmap(iWidth, iHeight, pxImagePattern)
        gdImageGrp = Graphics.FromImage(bmpImage)
        gdImageGrp.Clear(Color.White)
        gdImageGrp.TextRenderingHint = TextRenderingHint.AntiAlias
        gdImageGrp.DrawString(sTextToImg, fntImageFont, New SolidBrush(Color.Red), 0, 0)
        gdImageGrp.Flush()
        Return bmpImage
    End Function
