display images from picturebox one at a time
Mar 1 2010 4:41 PM
Hello
I have been working on this problem for awhile, I finally got my binary images to load into a picturebox, the user will select from a combobox and then that selection will pull a picture or pictures from a category, the problem I am having is if the category has more then one picture it will go through the row count and the last count will show the picture. I would like to have the first picture displayed and then when the user is through looking can click a button and the next picture will show and so on, I can't seem to bind the picturebox or trying to use bindingmanager base , here is my code I have
public
void
button1_Click(
object
sender,
EventArgs
e)
{
if
(comboBox1.SelectedItem.ToString() !=
""
)
{
string
instrPic = comboBox1.SelectedItem.ToString();
SqlConnection
roy1 =
new
SqlConnection
(
@"server=CAPTSISKO-PC\SQLEXPRESS;Initial Catalog=cable;Integrated Security=True"
);
roy1.Open();
string
newPic =
"Select * from guidePic WHERE picTitle = '"
+ instrPic +
"'"
;
DataSet
ds =
new
DataSet
();
SqlDataAdapter
da =
new
SqlDataAdapter
(newPic, roy1);
//_guidePic = BindingContext[da, "Pic"];
da.Fill(ds,
"newPic"
);
ArrayList
imagelist =
new
ArrayList
();
int
i = 0;
foreach
(
DataRow
dataRow
in
ds.Tables[
"newPic"
].Rows)
{
Byte
[] byteRoy =
new
Byte
[0];
DataRow
myRow;
myRow = ds.Tables[
"newPic"
].Rows[1];
byteRoy = (
byte
[])myRow[
"Pic"
];
MemoryStream
stimRoy =
new
MemoryStream
(byteRoy);
// pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;
int
originalW =
Image
.FromStream(stimRoy).Width;
int
orignalH =
Image
.FromStream(stimRoy).Height;
int
resizedW = (
int
)(originalW * .370);
int
resizedH = (
int
)(orignalH * .370);
Bitmap
bmp =
new
Bitmap
(resizedW, resizedH);
Graphics
graphic =
Graphics
.FromImage((
Image
)bmp);
graphic.DrawImage(
Image
.FromStream(stimRoy), 0, 0, resizedW, resizedH);
graphic.Dispose();
bmp.RotateFlip(
RotateFlipType
.Rotate90FlipNone);
bmp.Save(
"RoyNew"
);
PictureBox
PictureBox2 =
new
PictureBox
();
PictureBox2.Name =
string
.Format(
"pictureBox{0}"
, i.ToString());
// PictureBox2.Image = ((Image)bmp);
pictureBox1.Image = ((
Image
)bmp);
imagelist.Add(PictureBox2);
i++;
}
roy1.Close();
I have some other code in there where I tried to create a picturebox array but that is not working, I tried bindingsource also but apparently when I click the button that will not work.
any suggestions
