displaying a image in a winform's panel

Question

Hi I have a winform which contains two panels in which the first panel contains some textboxes comboboxes and buttons. In the second panel I have 4 buttons namely attach remove view front view and view back view and two radio buttons namely front view and back view. Now first I select the radio button front view and if I click the button attach then the form should take me to a folder images in the D drive( I am scanning the ATM card's front view and back view through the scanner and storing the scanned images in a folder images in the D drive) where I have some stored images(ATM cards front and back views).When I click the open button after selecting a image then it should take me back to the panel and display that image(ATM card's front view) that I have selected in the images folder. Similarly if I click the remove button then it should remove the image(ATM card's front view) from the panel2. Now I will select the radio button2 the back view and do the same operation as I did previously but the image(ATM card's back view)should overlap the first image(ATM card's front view) Now if I click the view front view button then it should display the ATM card's front view(that is the front view should overlap the back view) and if I click the view back view button then it should display the ATM card's back view (again back view should overlap the front view) can anyone help me to accomplish this with code.

Sachi Simply add a PictureBox in Panel 2 and add OpenFileDialog in Form. and in coding declare 2 variables to store file names of front and back view images Ex: String FView; String BView; and in Attach Button event add following code. openFileDialog1.InitialDirectory = D:\Images\; openFileDialog1.ShowDialog(); if (File.Exists(openFileDialog1.FileName)) { if (frview.Checked)//Front view RedioButton { FView = openFileDialog1.FileName; pictureBox1.Image = System.Drawing.Image.FromFile(FView); } else { BView = openFileDialog1.FileName; pictureBox1.Image = System.Drawing.Image.FromFile(BView); } } then in Remove simply set pictureBox1.Image = null; then in view front view button pictureBox1.Image = System.Drawing.Image.FromFile(FView); then in view back view button pictureBox1.Image = System.Drawing.Image.FromFile(BView); try this.

Sachii think DB didn't support \ symbol.before storing path you just replace \ with some other symbol and store it.while read it again you replace that symbol with \ symbol using replace() method of string. There must be an another way to store file path.try to find out that.and read the below discussion.it may help you. http://forums.mysql.com/read.php?10261367261367#msg-261367

vimal if the selected image is in bmp format then in db it is displaying the full name(I have a image namely karthiknpatel which is in bmp format) like below mysql> select * from drawings; +----------------+-------------------------------------+ | frontview | backview | +----------------+-------------------------------------+ | E:Imageg.jpg | E:Imagerigaderoad-bangalore06.jpg | | E:Imageg.gif | E:Imageskartiknpatel.bmp | +----------------+-------------------------------------+ 2 rows in set (0.00 sec) but the selected image is in the format other than the bmp then it is not displaying properly(you can see in the first row;the actual file name is brigaderoad-bangalore06 but it is not properly displaying.and also the folder name Images is also not displaying properly it is correct only for a file with bmp format-the second row second column) vimal is it possible to display in the format like below frontview backview E\Images\filename E\Images\filename

thanks vimal vimal in the form containing that picturebox I have a button called submit which stores the entered information into the db. My question is when I click submit it has to store the path location of that two images(front view and back view).To do this I can declare two string variables to store the path but I don't know how to assign the path to these two string variables

Sachi set PictureBox property SizeMode=AutoSize in properties window. Now picture box size will change automatically according to Image size.
