Hi,

   See after click or whatere it is …. OnOPageprerender Image will  be creating an image. And after creation image will be deleting.what my project is doing the same.I am giving that code.. below…

 

protected override void OnPreRender(EventArgs e)

{

LaodMainMap(ibMap); //Load MainMap by 

}

 

  public void LaodMainMap(System.Web.UI.WebControls.ImageButton imgMap)

        {

            MapFunction.Deleteimages();//delete Image form temp folder

            string imageLoc;

            string imageURL;

            imageObj imgRef;

            imgRef = MapFunction.Map.drawQuery();

            imageLoc = MapFunction.OutputDir + "/" + System.DateTime.Now.ToBinary() + "." + imgRef.format.extension;

            imageURL = imageLoc.Substring(imageLoc.IndexOf(MapFunction.OutputDirURL));

            imgRef.save(imageLoc, null);

            ibMap.Width = imgRef.width;

            ibMap.Height = imgRef.height;

            ibMap.ImageUrl = imageURL;

            MapFunction.IsMapInDirectory = false;

        }

 

This on Page Load

//Temp folder for storing legend map and keymap temp files 

  MapFunction = new RoulacGIS.MapFunctionality(this.Page, Server.MapPath(_AppSetting.TempFolder),

_ AppSetting.TempFolder);

                        //initialize map control

                        //Load Map

                        try

                        { LoadMap(); }

                        catch (Exception exp)

                        { exp.Message.ToString(); }

 

//this is separate method for accessing mapfile

public void LoadMap()

        { MapFunction.Map = new mapObj(Server.MapPath("MapFile/") + _AppSetting.MapFilePath); } //create map instance

 

I hope this will help you.

 

Thanks and Regards,

Venkat.

Thanks for the quick reply,

When you run this function? after each requests ? but if so, the client is able to read the image before you delete it ?

best regards,

Valerio

Hi,

 

  Why don’t you write method  for deleting png .mapserver will take care about creating an image.I have  C# code.

The below code will delete all the files form OutputDIR.

 

I hope it helps you. Or At least you can get some idea about your task.

 

Thanks and Regards

Venkat.

 

public void Deleteimages()

{

            try

            {

                foreach (string f in System.IO.Directory.GetFiles(OutputDir))

                {

                    System.IO.File.Delete(f);

                }

            }

            catch (Exception exp)

            { }

}

Dear all,

I have a demo where I'm using mapserver cgi interface. I'm using the browse mode so each time mapserver receive a request, it creates a temporary png on the server filesystem. 

Do you know how and when i can delete those temporary image since they are used only one time ?  

An attacker could easily  fill all the server HD  locking all the system.

Thanks

Valerio
