This is Good Afternoon Guys! I have a little difficulty in passing my registered photo to my PictureBox to update the registry.

My scenario is this::

I have a Form data entry registration and
A Form that makes the search of the register that is presented in a DataGridView and when clicked on the record it returns me the data for registration form so that I can do the update;

Well I insert the data and the photo converted to binary, using db sqlserver more difficult to pass the photo to my picture, the other fields I can bring, but not the photo.

Note: it’s my first time working with photo in WPF.

follow my code, guys.

<-- This is from my DataGridView where I select the cell by throwing the dice to the form criminal record-->

   int linhaNumero = 0;
    byte[] foto_array;

private void dgw_Onibus_MouseDoubleClick(object sender, MouseEventArgs e)
    {
        try
        {
            if (lblOperacao.Text == "Aluno Master")
            {

                DataGridViewRow dr = dgw_Onibus.SelectedRows[0];
                this.Hide();

This is my table where I entered the data "My column Tb_imageuser" is where I store my image!

Thanks for your help!

It’s winforms or wpf?

Hello Leandro! Application is in WINDOWS FORMS

and you’re sure that foto_array is getting a byte[] of that image?

Have you tried changing this line: frm.picFoto.Image = Image.FromStream(ms); for this frm.picFoto.Image = new Bitmap(ms);.

Hello @Joãomartins did the test with the change, but it didn’t work either.

Has the image been correctly recorded in the database? The byte array has the correct image?

– João Martins

2018/08/09 at 10:12
was recorded yes @Joãomartins the insertion of the data with the photo ta inserted in the database, the problem being to bring back the image. the character data I made the test all comes, only the photo that does not!

How are you saving the image to the database? Edit your question and enter the pf code.

– João Martins

2018/08/09 at 10:29
Ready @Joãomartins made the change so I can better understand my scenario.

– Lucas_Silva

2018/08/09 at 10:43
What kind is your column that holds the image?

– João Martins

2018/08/09 at 10:49
Initially I had left this column as 'image', but I searched more and saw that 'VARBINARY' is better for image storage! so I left it as VARBINARY.

Guys managed to solve this problem I was forgetting to call the method in my global class of my dataset.

what I did was this

in my global class where I call all my methods I created

public DataSet ds;

and then I called him in my search form to throw the data in the main form of registration.

cg.ds = new DataSet();

after that I just changed my line

if (ds.Tables[0].Rows[linhaNumero][6] != System.DBNull.Value)

for

if (cg.ds.Tables[0].Rows[linhaNumero][6] != System.DBNull.Value)
{    
    foto_array = (byte[])cg.ds.Tables[0].Rows[linhaNumero][6];    
}

Guys I managed to solve again the problem I was quoting above! I’ll leave it here in case anyone needs it!

foto_array = (byte[])dr.Cells[6].Value;

this was the change for each cell of the datagridview to take the photo and play in the main form of each selected user.

by Felipe Reginaldo • 1 point · Answer 3 · 2020-05-20T21:49:24+00:00

plain as that:

Memorystream ms = new Memorystream((byte[])dataGridView1.CurrentRow.Cells[0].Value ); pictureBox1.Image = Image.Fromstream(ms);
