so it not compulsary to make seperate pictureboxes
while loading picture, give its path or file name to a label or a string
and when picturebox clicked, you will know about the picture

the best way which i think is that storing all the images with similar sequential name like 1.jpeg,2.jpeg...
then take a pic box n a timer so in the form load function write something like this
picbox.backgroundimage = image.fromfile("c:\\" + i ".jpeg");
i = i+1;
run a timer which repeats the above function
i hope this will work as i have done it before
its me sid

It makes a lot of sense but how can i create the different picturebox for each pic, because even if i have the timer at 10 miliseconds it will always be the same and if i am calling a method from it, it will always call the same method?
I need to create different pictureBox because i will have a touchscreen where end users will select picture they like the most.
So to a given folder containing the pics i will give it a picture for each pic to make sure i control all pictures.
My problem is that i can be given 2 pictures but i also can be given 100 pictures...
Thanks... a lot!!

I dont have much idea but a clue i hope it works
step 1. take a pic box array
2. Count the no of pics in the folder
3. now run a loop to show the pic boxes as accordint to no of pics
4. Assign proper top n left values to the pic boxes
i hope this will be useful ...any way nice question 4m u
its me sid

I think I was doing that before i posted the question and i received an exception that i did not do how to correct...
//images is an array that contains all images in the given folder
images = loading.Loading();
//loading.cant() returns the number of files contained in the folder
PictureBox[] pics = new PictureBox[loading.cant()];
foreach (Image img in images)
{
//with ImagesList i can display the images but not let them be in the form until it closes
ImagesList.Images.Add(img);
}
//i added this loop to have a better control of the array of pic
for (int i = 0; i < loading.cant(); i++)
{
//both codes generates an execption can you tell me why?
//pics[i].BackgroundImage = images[i];
pics[i].BackgroundImage = ImagesList.Images[i];
pics[i].Show();
}

Picture boxes are a waste of time. Write your own paint handler and then render as many images as are appropriate for your screen size and image size.

I like that idea a lot better but can you please point how to start my own paint handler?
I am a little rookie to describe myself in a positive way but i don't know much of images processing.
Thanks...

Handle the paint event. It's passed a graphics object. You can use the DrawImage methods on that object to draw images direct to your screen.

Thanks... I guess that's the signal to start reading something new...
I love this project, i surely do... It has made me learn from network programming to Images processing...
I think after this i want to become a programmer!!!
Thanks again!

I didn't get it to work the way you advice me, not because it did not work that way but because my lack of knowlege, but i did get it to work like this:
void Form1_Paint(object sender, System.Windows.Forms.PaintEventArgs e)
{
int totalPics = loading.cant();
while (cantPictures < totalPics)
{
PictureBox P = new PictureBox();
Bitmap imag;
if(cantPictures <= 5)
{
if (cantPictures == 0)
{
imag = new Bitmap(images[cantPictures]);
P.Image = imag;
P.Click += new EventHandler(P_Click);
P.Size = new Size(150,150);
P.SizeMode = PictureBoxSizeMode.StretchImage;
P.Location = new Point(35, 10);
constante = 35 + P.Size.Width+10;
this.Controls.Add(P);
}
else
{
imag = new Bitmap(images[cantPictures]);
P.Image = imag;
P.Click += new EventHandler(P_Click);
P.Size = new Size(150, 150);
P.SizeMode = PictureBoxSizeMode.StretchImage;
P.Location = new Point( constante, 10);
constante += 10 + P.Size.Width;
this.Controls.Add(P);
}
}
Now i have a little problem adding the Click Event individually, any advice there?

That is soo true it does have all i need.
I am going to ask the owner to let me use some of his code if it is possible.
I like to ask for permission even if it is open.
Thanks a lot,
Best regards!!!

Erhm, not having a dev env here right now, but this should be pretty close...
<br />
DirectoryInfo diPictureFolder = new DirectoryInfo("c:\\Your\\Pics\\");<br />
foreach (FileInfo fiPic in diPictureFolder.GetFiles("*.jpg"))<br />
{<br />
PictureBox pb = new PictureBox();<br />
pb.Image = new Bitmap(fiPic.FullName);<br />
pb.Click += new Event handler for click event<br />
yourForm.Controls.Add(pb);<br />
}<br />

Hi Friends,
Kindly give the method, How may I set "F10" key in "MDI/Main" form to close application?
Thank you
(Riaz)
|
|
|
|
|
if (e.KeyCode == Keys.F10)
Application.exit();
But remember it will run when you are having the focus onto the MDI form.
It will not work when any child form is open.

1. Set KeyPreview to True in the properties of Main form
2. Write the following code in the Keypress event of Main Form
if(e.KeyCode == keys.F10){<br />
Application.Exit();<br />
}
Hope it helps.

Hi....i need to implement scanner in one of my project to read the barcode...how can i do it in windows applications with c#?
vicky

Hi,
If you are going to use the actual hardware, then you will have to connect it and get data from it. Otherwise, you'll have to detect and extract the exact place in the image, where the barcode is, and then read it as its specifications.

Adeel

thanks for your support....i am going to use actual hardware for it...do i have to use any supporting dll for that...if yes, what is it and how to use it?
|
|

|

For that you will have to check what interface the barcode reader has i.e. will you connect it using serial port, USB port or parallel port. After that you need to look-in the specifics of the barcode reader, like in what format it sends/receives data, what commands it supports, that mainly depends on the make and the chip design of the barcode reader.
Hope that helps!

most barcodescanners act like a keyboard so you won't need anything special.

Hello experts,
I have a combo in that I fill some values from Db say A,B,C,D,e,f,G,h,i,j etc.
My combo is a simple combo so end user can also type in that. for data consistency I check wheather or not the user select proper value or not...? That is user have to enter or select the pre-filed value. For that I am using the Contains method
like
comboBox1.Items.Contains(comboBox1.Text.ToString()
and its working fine.
But this will interperete A and a different ....What to do...?
I want a and A are the same
Regards
Pankaj Joshi

One idea might be to do a string comparison between the objects in the combobox and the the value inserted by the user
for (int i = 0 ; i < cmb.Items.Count ; i++)
{
if (String.Compare(cmb.Items[i].ToString,cmb.Text,true)
{
}
else
{
}
}
Hope it helps.
I will use Google before asking dumb questions
