I'm trying post base64 code to save as an image but I can't post the value of textbox when I try submit my base64 code.
Is there limit send to codes via posting form?
I get an error due to can't get the value of textbox below:
ADODB.Stream error '800a0bb9'
Arguments are of the wrong type, are out of acceptable range, or are in conflict with one another.
My HTML code
<form method="POST" action="?X=1" id="myForm">
<input type="text" name="img_val" id="img_val" value="" />
<input type="submit" value="Submit Largest Code" />
</form>
My ASP codes:
<%
IF LEN(Request("X"))>0 THEN
base64String = Trim(Request.Form("img_val"))
Set tmpDoc = Server.CreateObject("MSXML2.DomDocument")
Set nodeB64 = tmpDoc.CreateElement("b64")
nodeB64.DataType = "bin.base64"
nodeB64.Text = Mid(base64String, InStr(base64String, ",") + 1)
set bStream = server.CreateObject("ADODB.stream")
bStream.type = 1
call bStream.Open()
call bStream.Write(nodeB64.NodeTypedValue)
caminho=Server.MapPath("/SS/imagem.png")
call bStream.SaveToFile(caminho, 2)
call bStream.close()
set bStream = nothing
END IF
