Fórum Probema com caminho da imagem. #6445

Coloquei o projeto no disco..

aqui está o link
https://www.devmedia.com.br/imagens/discovirtual/211069/Hoffmann1.7.rar

Realmente o endereço da imgem está sendo salva no banco de dados, mais a imagem não está sendo salva dentroda pasta Thumb424 eThumb65.

Utiliza Server.MapPath("~/Images/Thumb424" + upload.FileName);

Se for apenas trocar o  Server.MapPath("~/images/Thumb424" + upload.FileName); , fiz assim mais não funcionou.   private void saveImage() { FileUpload upload = (FileUpload)frmAdd.FindControl("upImage"); String path = Server.MapPath("~/images/Thumb424" + upload.FileName); if (!File.Exists(path)) { if (upload.HasFile) { // To enable this sample, grant Write permission to the ASP.NET process account // for the Images subdirectory and uncomment below lines of code. upload.SaveAs(path);   #region Imagem Maior using (Bitmap bitmap = new Bitmap(upload.PostedFile.InputStream, false)) if (bitmap.Width > bitmap.Height) { int wi = bitmap.Width; int he = bitmap.Height; int novaAltura = (wi * 140) / he; CreateThumbnail(140, novaAltura, path, Server.MapPath("~/images/Thumb424/" + upload.FileName));   } else { int he = bitmap.Height; int wi = bitmap.Width; int novaLargura = (wi * 139) / he; CreateThumbnail(novaLargura, 139, path, Server.MapPath("~/images/Thumb424/" + upload.FileName)); } #endregion #region Imagem Menor using (Bitmap bitmap = new Bitmap(upload.PostedFile.InputStream, false)) if (bitmap.Width > bitmap.Height) { int wi = bitmap.Width; int he = bitmap.Height; int novaAltura = (he * 65) / wi; CreateThumbnail(65, novaAltura, path, Server.MapPath("~/images/Thumb65/" + upload.FileName)); } else { int he = bitmap.Height; int wi = bitmap.Width; int novaLargura = (wi * 65) / he; CreateThumbnail(novaLargura, 65, path, Server.MapPath("~/images/Thumb65/" + upload.FileName)); } #endregion }   }   }

Você baixou os fontes do projeto?

Perceba que eu faço desta maneira e da certo.

Fabio

sim, estou fazendo exatamente com no seu curso.

a questão é que aqui não funciona. Será que pode ser outra coisa? O random está funcionando, o bd tmb.


meu site está nesse diretório, em minha máquina.

D:\Trabalhos\WebSites\Hoffmann1.7.4\Hoffmann1.7.3\Hoffmann1.7

será que isso tem alguma coisa a vê?

o que pode está acontencendo?

esse é o html que está retornando ..

 <input type="image" name="ctl00$ContentCenter$dtListRandom$ctl01$ImageButton1" id="ctl00_ContentCenter_dtListRandom_ctl01_ImageButton1" src="images\Thumb65\camisasantos.jpg" onclick="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(&quot;ctl00$ContentCenter$dtListRandom$ctl01$ImageButton1&quot;, &quot;&quot;, false, &quot;&quot;, &quot;ShopItem.aspx?ProductID=61&quot;, false, false))" style="border-width:0px;" /></td>


O Problema que quando eu faço upload a imagem não está indo para dentro da pasta Thumb424 Thumb65.

Pelo que eu entendi da sua aula, é salvo apenas o endereço da imagem no banco e a imagem fica salva dentro da pasta.

Depois usar imagebutton pegando o endereço da imagem  db e chamar a img da pasta images/Thumb...

na pagina produtos estou chamando o método normalmente..

 protected void frmAdd_ItemInserted(object sender, FormViewInsertedEventArgs e)
    {
        saveImage();
    }


novamente o método saveImage



    private void saveImage()
    {

        FileUpload upload = (FileUpload)frmAdd.FindControl("upImage");

        String path = Server.MapPath("~/images/" + upload.FileName);

        if (!File.Exists(path))
        {
            if (upload.HasFile)
            {

                // To enable this sample, grant Write permission to the ASP.NET process account
                // for the Images subdirectory and uncomment below lines of code.
                upload.SaveAs(path);


                #region Imagem Maior
                using (Bitmap bitmap = new Bitmap(upload.PostedFile.InputStream, false))
                    if (bitmap.Width > bitmap.Height)
                    {
                        int wi = bitmap.Width;
                        int he = bitmap.Height;
                        int novaAltura = (wi * 140) / he;
                        CreateThumbnail(140, novaAltura, path, Server.MapPath("~/images/Thumb424/" + upload.FileName));


                    }
                    else
                    {
                        int he = bitmap.Height;
                        int wi = bitmap.Width;
                        int novaLargura = (wi * 139) / he;
                        CreateThumbnail(novaLargura, 139, path, Server.MapPath("~/images/Thumb424/" + upload.FileName));
                    }
                #endregion

                #region Imagem Menor
                using (Bitmap bitmap = new Bitmap(upload.PostedFile.InputStream, false))
                    if (bitmap.Width > bitmap.Height)
                    {
                        int wi = bitmap.Width;
                        int he = bitmap.Height;
                        int novaAltura = (he * 65) / wi;
                        CreateThumbnail(65, novaAltura, path, Server.MapPath("~/images/Thumb65/" + upload.FileName));

                    }
                    else
                    {
                        int he = bitmap.Height;
                        int wi = bitmap.Width;
                        int novaLargura = (wi * 65) / he;
                        CreateThumbnail(novaLargura, 65, path, Server.MapPath("~/images/Thumb65/" + upload.FileName));
                    }
                #endregion

            }


        }


    }

    public void CreateThumbnail(int largura, int altura, string srcpath, string destpath)
    {
        System.Drawing.Image img = System.Drawing.Image.FromFile(srcpath);
        System.Drawing.Image imgthumb = img.GetThumbnailImage(largura, altura, null, new System.IntPtr(0));
        imgthumb.Save(destpath, ImageFormat.Jpeg);
        img.Dispose();
        imgthumb.Dispose();
    }

Não estou conseguindo resolver, o que vc sugere?

Como você está escrevendo na pasta pode ser permissão, você já debugou a aplicação para ver se da erro no momento que vai salvar. Coloque permissão de escrita na pasta que está salvando.

Fábio, estava chamando o método no formView errado. Acertei isso e agora está aparecendo o seguinte erro.
