PostedFile.SaveAs i upload i asp.net

[ Neznalica_sa_ugla @ 06.07.2011. 10:55 ] @

E pitao sam svašta do sada ( kada pametno kada glupo) , ali nisam nikada bio zbunjen kao sada .
Koristim na više stranica koje sam radio isti kod za uplod slike na server i svugdje radi besprijekorno: da vas ne bih gnjavio cjelim kodom samo cu staviti isjecke
srana aspx

Code:

   <asp:FileUpload ID="myFile" runat="server" BackColor="BurlyWood"  />

                <asp:Button ID="btnUpload" runat="server" Text="Upload"
                OnClick="UploadFile" OnClientClick="javascript:showWait();"/>

strana c#

Code:

if (myFile.HasFile)
            {

                odredisna = myFile.FileName;
                string put = Server.MapPath(".");

                try
                {
                 myFile.PostedFile.SaveAs(put + "\\img\\" + odredisna);
                 Msg = "uspjesno preneseno " + myFile.PostedFile.ContentLength.ToString() + "  od ukupno " + myFile.FileBytes.Length.ToString();

                }
                catch
                {
                    Msg = "Doslo do  greske : Prevelika datoteka ili  Slaba  veza  ili lokacija nije pronađena ";
                }

}

To nikako da mi proradi u ovoj stranici : Framwork je 4. , vidi file u uđe u try i onda stane , file nije prevelika ,da to može da bude problem

Jednostavno više nemam nikakvu ideju , Admin servera, ko pokvarena ploča ; img folder gde se smešta slika , je virtualan , i dozvoljeno je w/r.
Pomagaj te braćo .I Hvala

Verovatno kada bi sacekao, docekala bi te greska...

Ovako, proveri u web.config da nemas ovu liniju sa ogranicenjem ili da je dodas radi probe:

Code:
<system.webServer>
....
        
...
</system.webServer>

[ deerbeer @ 06.07.2011. 12:33 ] @

Neka proba da ispise gresku bez dodavanja brejkpointa i pauziranja izvrsenja :

Code:

catch (Exception exc)
{
Msg = "Doslo do greske : " + exc.Message;
}

Ne verujem da je fajl veliki jer onda ne bi ni usao u "try" vec bi pukao odmah pre nego sto server hendluje trazenu stranicu .

[ Neznalica_sa_ugla @ 06.07.2011. 21:42 ] @

nema niša slično u web.config, niti poruke o greški , ni to ne mogu uhvatiti .

[ pl4stik @ 07.07.2011. 07:32 ] @

AFAIK moraces da resavas to na nivou aplikacije tako da ti sve strane ne prenesu preko onoliko koliko definises u web.configu (kao sto je dejanet napisao). Po defaultu u machine.configu web servera je 4Mb.

Ajde zaobidji metodu SaveAs i probaj postupno da upisujes iz streama u niz bajtova pa onda u fajl .

Code:

try
{
// kolika je duzina fajla u bajtovima
int FileLen = myFile.PostedFile.ContentLength;

//napravi bafer za fajl na osnovu procitane duzine
byte[] input = new byte[FileLen];

Stream MyStream = myFile.PostedFile.InputStream;

// iz dolaznog streama fajla smesti sadrzaj u novo kreirani bafer
MyStream.Read(input, 0, FileLen);

// zapisi sve bajtove u zeljeni fajl
File.WriteAllBytes(put + "\\img\\" + odredisna,input);

}
catch (Exception exc)
{
   Msg = "Doslo do  greske : " + exc.Message;
}

Ovo slicno bi trebalo da radi metoda SaveAs , ali ovako ces videti duzinu fajla ulazni strim , i da li uspeva da se procita fajl koji je dosao post metodom .
I proveri obavezno putanju fajla (put + "\\img\\" + odredisna) za svaki slucaj uradi copy iz quick watch-a pa paste u explorer .

Da to se desi kad je file uploadovan (upisan na disk), a ovde je problem sto (posto Win prvo uploaduje ceo file u memoriju pa onda upisuje na disk) se ex desi dok se file uploaduje u memoriju tako da ga na hdd-u jos nema da bi ga merio...

Baca grešku :: Mada su postavljene kvačice na sve moguće na ovom folderu :

Da li je moguće da ipak web.config , promjeni privremeno postavke ??? ;
evo web.config

Etooooo, sad imash (big, fat) ex ;)

Sto se tice web.configa, tu mozes da overrideujesh ono sto imash definisano u machine.configu ali ne mozes da menjash postavke servera... Npr. ovo ne mozes da resis u web.configu afaik :)

[ Neznalica_sa_ugla @ 08.07.2011. 12:16 ] @

Vraga , etooo , , nikako da ja to promenim u CP ;

[ pl4stik @ 08.07.2011. 12:33 ] @

Noup.

Uploaduj u bazu ...

[ pl4stik @ 30.07.2011. 22:50 ] @

Pogresio sam, ovo se resava bas u web.configu i u sustini izaberesh folder za upload i u njemu napravish web.config file sa sledecom sadrzinom:

Code:
<?xml version="1.0"?>
<configuration>
    <appSettings/>
    <connectionStrings/>
    <system.web>
        <identity impersonate="true" userName="domein\username" password="password"/>
    </system.web>
</configuration>

Sada mozes da uploadujesh ali strana sa koje uploadujesh mora da bude u tom folderu
