How is your mapfile looking like? Which mapserver version are you testing with. Tamas 2008/8/13 Hallgren, Johan [EMAIL PROTECTED]: Hello Tamas I'm glad that you supports me here:) We are getting closer to the problem:) Your code (getbytes.exe) runs fine on my own pc, but when I move the code to the server the problem starts. I made a new project with your cs-file and named it getbytemap, but it's actually the same code as the getbytes.exe. The output below doesn't actually write the error but the GetBytes: is the first part och the exception message. I can guess that the memory already is corrupt. When I do the same with the debugger you can see the watch output below. One difference I have in mind compared to other environments I have used is that this server have more power. In the task manager there is eight CPUs. The problem is deterministic with the getbyte-code.

Re: [MAPSERVER-USERS] Memoryproblem
I use mapscript c# in my project running in ms win 2003 std/ent r2 and iis6
all works perfect, but some problem related with writing png's exists in
.net (v 2/3.5)
imageObj imgRaw=null;
imgRaw = map.draw();
//this works (without changing image format)
using (MemoryStream ms = new MemoryStream(imgRaw.getBytes()))
ms.WriteTo(response.OutputStream);
//or this (note: the second memory stream,actually, needed only for
iutputing png's!)
imageFormat = ImageFormat.Png;
using (Image img = Image.FromStream(new MemoryStream(imgRaw.getBytes(
{
using (MemoryStream ms = new MemoryStream())
{
img.Save(ms, imageFormat);
ms.WriteTo(response.OutputStream);
}
}
before version 5.2 I had memory corruption problems in some web service
requests (reason - unknown, perhaps it was related with postgis bug - ticket
now closed) during map.draw(), but now all ok.
+consideration: mapserv.exe (especially in fastcgi mode) much more faster
