SIMPLE BROWSE BUTTON QUES: How to save the value on submit

THis is my file field
<input type="file" name="upic2" value="<%=upic2%>">
If this was a regular field, value="<%=upic2%> would hold the value, but is doesnt work for the browse field. Does anyone know what I am missing.
THanks
Adam

I take it that this will not work and its a limitation of the browse button.

  • How to save the value in Cedit control into a text file bu using measurement studio c++?

    Im using measurement studio c++ to create a application. How to save a randomly generated value which display in the CNumberEdit Control to a text file? how to do the coding part?

    You can use the CNiFile class to write the value out to a file. For example, create a new Measurement Studio C++ project and follow these steps:
    Add a CNiNumEdit to the dialog.
    Add a member variable for the CNiNumEdit called m_numEdit.
    Add a button to the dialog.
    Double-click the button to add a message handler for the button's BN_CLICKED message.
    Add the following code to the button's BN_CLICKED message handler:
    CNiFile file("C:\\Values.log", CFile::modeCreate | CFile::modeWrite | CFile::typeText);
    file << m_numEdit.Value << endl;
    file.Close();
    Run the application, edit the CNiNumEdit's value, and click the button. The value should be written to the Values.log
    file as specified in the code above.
    Hope this helps.

  • How to ask for an array and how to save the values

    I'm supposed to be learning the differences between a linear search and a binary search, and the assignment is to have a user input an array and search through the array for a given number using both searches. My problem is that I know how to ask them how long they want their array to be, but I don't know how to call the getArray() method to actually ask for the contents of the array.
    My code is as follows:
    import java.util.Scanner;
    import java.util.ArrayList;
    public class Main
        private static Scanner input = new Scanner(System.in);
        public static void main (String args[])
            //creates ArrayList
            int List[];
            System.out.println("How long would you like the array to be?");
            int arrayLength = input.nextInt();
            //Initializes array list
            List = new int [arrayLength];
            System.out.println("Please enter the first value of the array");
        public static void getArray(int List[], int arrayLength)
            for(int i=0; i < arrayLength; i++) {
                 System.out.println("Enter the next value for array");
                 List[i] = input.nextInt();
         public static void printArray(int List[])
             for(int i=0; i < List.length; i++)
                 System.out.print(List[i] + " ");
    public class search
        public static int binarySearch(int anArray[], int first, int last, int value)
            int index;
            if(first > last) {
                index = -1;
            else {
                int mid = (first + last)/2;
                if(value == anArray[mid]) {
                    index = mid; //value found at anArray[mid]
                else if(value < anArray[mid]) {
                    //point X
                    index = binarySearch(anArray, first, mid-1, value);
                else {
                    //point Y
                    index = binarySearch(anArray, mid+1, last, value);
                } //end if
            } //end if
            return index;
        //Iterative linear search
        public int linearSearch(int a[], int valueToFind)
            //valueToFind is the number that will be found
            //The function returns the position of the value if found
            //The function returns -1 if valueToFind was not found
            for (int i=0; i<a.length; i++) {
                if (valueToFind == a) {
    return i;
    return -1;

    I made the changes. Two more questions.
    1.) Just for curiosity, how would I have referenced those methods (called them)?
    2.) How do I call the searches?
    import java.util.Scanner;
    import java.util.ArrayList;
    public class Main
        private static Scanner input = new Scanner(System.in);
        public static void main (String args[])
            //creates ArrayList
            int List[];
            System.out.println("How many values would you like the array to have?");
            int arrayLength = input.nextInt();
            //Initializes array list
            List = new int [arrayLength];
            //Collects the array information
            for(int i=0; i < arrayLength; i++) {
                 System.out.println("Enter a value for array");
                 List[i] = input.nextInt(); 
            //Prints the array
            System.out.print("Array: ");
            for(int i=0; i < List.length; i++)
                 System.out.print(List[i] + " ");
            //Asks for the value to be searched for
            System.out.println("What value would you like to search for?");
            int temp = input.nextInt();
            System.out.println(search.binarySearch()); //not working
    }

  • How to save the text from text area back to a text file?

    Hi all,
    Now I am doing a small panel which containts a JTextArea, this TextArea will read the content from a text file, then display the content of the text file on the TextArea itself.
    My idea is, allow the user to modify the content in the textarea (I set it Editable=true;), then save it. After the user press the save button, the content in the text file will be updated accordng to the user;s modification on TextArea.

  • How to save the JFrame

    how we save the JFrame dynamically???????/

    hiiii
    i'm a student doing my project in real time video processing, wherein we plan to accept real time images 4rm the web camera. We wish to divide the main frame of our front-end into 3 parts. One will display the video coming in 4rm the webcamera & the other side of the screen(front-end) the processed video.
    The third part will consist of radio buttons, textboxes,etc, which we will use to adjust contrast,sharpening,etc. the changes must happen on the video as it comes in. The original video should continue to show as normal, and the processed video should reflect the changes. This should allow us to thus compare the two.
    Please suggest us some way of implementing the above using JMF. We have been able to get the video as it is captured from the webcam. However we are not able to figure out how to implement the second video screen after applying the various techniques, so that it appears as a real time video.
    Any help or suggestions in this regard will be appreciated.
    thanx,
    Leon.

  • I want to use Get Panel Image in Labview 5.0.1 and need details on how to save the BMP data generated

    I am trying to generate an application that saves a copy of its front panel on completion. This is easy to do using an invoke node with Print VI to HTML but this does not work in an .exe format. I have seen elsewhere that you have to use the Get Panel Image method, but no details are supplied in LV 5.0.1 documentation of how to use the "image" data (1-D Unsigned Byte array) that is generated. I want to save this in a format that can then be read as a bitmap in any standard graphics package. Any assistance?

    Hi,
    If you'd upgrade to LV5.1 or 6 you could use the 'standard' vi's for this.
    You need a VI called "Write BMP File.vi". It's not shipped with LV5.0.1.
    This vi only uses 3 subVI's, so perhaps someone at NI can convert it and
    send it to you (sorry, I won't, it's copywrited).
    If you cannot get this VI anywhere, you'll need to figure out the BMP file
    format yourself. It's not too complicated, but still could take some days.
    Perhaps someone figured it out before LV5.1 was released.
    Regards,
    Wiebe.

    This isn't an Animate-specific issue, but I thought I'd take a stab at it anyway.  As with anything else on the web, you need to have a server script to handle incoming data, so it's all back end work.  Your page will need to call that script and provide parameters to that script that it can read.
    The easiest way I can think of to do this (and this is all highly theoretical, so please make sure it's secure before you implement it) is to create a 1px div that has visibility off.  Whenever you click, you can load your URL in that div, which then increments your counter on your db.
    Hope that helps inspire some interesting solutions!

    Can you clarify something? You want to know how many times someone has clicked a particular animation. Are you wanting to store the click as soon as they click it? So for example:
    User sees animation.
    They click to continue and go to some other page.
    You want to know how many times they've done that.
    Is that what you mean?

  • How to get the value assigned in dropdowmlistbox as well as radio button

    Hi Everybody,
       Please help me to find the solution for the following:
       1. How to get the value assigned in dropdowmlistbox?
       2. How to get the value assigned in radio button?
      I am waiting for the answer and reply...
      Thanks & Regards,

    The radio button has a name attribute. That name attribute should be the same as the bean property. Then you just need a
    <jsp:setProperty name="mybean" property="*"/>
    and the bean's set method will be called for the value of that radio button.
    so...
    <input type="radio" name="doit"/>
    class MyBean
    public void setDoit( boolean yes )
    //do whatever here
    }
