C Sharp :: Passing Values In Another Textbox?
Apr 27, 2012
I have an ms access database with 2 tables in it which I named Customers and Products. I am using visual studio 2010, in my windows form I have 4 textboxes and 3 button in it, for my 1st textbox when I entered one of my ProductCode such as 10111, then press the Display button, the other remaining 3 textboxes should populate and display the following;
ProductID: CH001
ProductName: Chocolate Strawberry
ProductCode: 10111
Then the 2 remaining button named NEXT and PREVIOUS, should be able to display all my product name with 10111 product code.

I am not able to get my textbox values in my Register class for my calcTotal method. However, if I convert the text to a double in the Form class and then pass that to my function it will work. But I don't understand why I need to do it like that.
namespace CashRegister {
class Register : Form1 {
public double getItemPrice(string str) {
double item = 0;
item = Convert.ToDouble(str);
return item;

I have managed to make text dynamically appear in a text-box while I enter text into another.
how ever I would like to know to to limit the amount of text that is dynamically entered(I'd say about 10 characters at most).
here's a sample of what I have done so far:
Random r = new Random();
int IDrandom = r.Next(0, 9);
Emp_ID.Text += IDrandom.ToString();
//Emp_ID.MaxLength = 10; does not work

I'm trying to get some more user friendly things in my program done. Now I'm trying to filter by typing in a text box and it filters to what you are typing and shows the entire row.
This is what I currently have:
private void txtFilter_TextChanged(object sender, EventArgs e) {
try {
SQLiteConnection connect = new SQLiteConnection(connString);
connect.Open();
[Code] ....
I get an exception error though:
SQLite error
near "'N'": syntax error
// N is what I started typing to start the filter.
Ok, so I've edited the code now to this:
private void txtFilter_TextChanged(object sender, EventArgs e) // FILTER TODO {
DataView view = new DataView();
SQLiteConnection connect = new SQLiteConnection(connString);
connect.Open();
view.RowFilter = "Channel like '%" + txtFilter.Text + "%'";
}
No more exception errors, just not what I want it to do. It just keeps everything there.

The program asks for to ask the user for how many students there are, and how many strawberries they picked. The farm gets to keep half and the students get to keep the rest.
I am using functions and passing values to one function to another. I know I am making it harder then I need to, but I want to work with functions more and passing values. I figured it was better to practice with simple programs.
Code: #include <stdio.h>
float people(float);
float strawberries(float x);

I am trying to get some confirmation about how to pass to functions. If you want to assign default values to certain parameters, and have others defined inside the body of int main(), then the parameters which will have default values go at the end of the list. Is that correct?
i.e. The following code is wrong, because we cannot leave a black in the function call on the third line of the main function. However, if we switch the prototype to void Passing (int a, int c, int b = 1); and the function definition to void Passing (int a , int c, int b) everything will be okay and we can call the function as Passing (a, c).
In brief, we cannot do this EVER:
Passing( a, , c)right?

So form two needs to pass information that was typed in its text box to form 3. So then form 3 can use this information. I think I am creating a new instance of form 2 because I get the exception can not divide by 0 so it is empty even if I typed in a integer in the text boxes. How to pass information from the textbox to a var that can be used in another form.
public partial class MapProperties : Form {
private int _numRows;
public int NumRows {
get { return _numRows; }

passing selected row in gridview to my dropdown. I have 1 gridview, 1 textbox and 1 dropdown list box. My dropdown is populated by SqlDataSource from my table Country. On my gridview, I have 3 columns, which are SELECT, NAME and COUNTRY. Under SELECT column, I have my hyperlinked Select, every time I clicked on a certain row NAME will pass in textbox (no problem with that), but in my dropdown it does not populates the COUNTRY that I choose. For example, I have Jack for name and USA for country. Beside Jack and USA, I have a hyperlink Select, when I click Select, Jack will display on my textbox and supposed to be USA will display on my dropdown but not displaying instead it says an error "'cboCountry' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value".
I have tried the codes below:
protected void GridView2_SelectedIndexChanged(object sender, EventArgs e)
{
txtname.Text = GridView2.SelectedRow.Cells[1].Text;
cboCountry.Text = GridView2.SelectedRow.Cells[2].Text;
}
Only the textbox os working, no luck at all in dropdown...I'm using c# and asp.net.

I'm working through the Let us C book. One exercise asks me to collect int and float , then pass them to a function that gets product of these and returns it to main. My code looks like this:
Code:
#include <stdio.h>#include <stdlib.h>
main()
{
int a;
float b, c;
[Code]...
So while compiling i get an error about conflicting types for product. I tried to google that error but couldn't understand what's the problem. My only clue is that i can't pass int and float to a function at the same time... Could that be it?

I am currently writing a program which needs an edit form. This form is to edit a country in the datagridview which I have. I am however confused about how to pass the data from the data gridview in the main form to the relative places on the edit form. I have done most of the coding as shown below. I know I need a method in my AVL class to return all the information of the selected country back to the main form method which then passes it back to the edit form and displays it. I am unsure what to pass and what to write in this method.
Main form method
public void button2_Click(object sender, EventArgs e)
{
// creates new form referencing data grid view and AVL Tree
EditCountryForm editform = new EditCountryForm(ref this.countryTree, dataGridView1);
string CountryName = "";
//set name of country selected to string
[Code]...

Basically I have to create an array, fill it, and then print it on screen. The tricky thing is that need to use pointers to fill it and print and later on sort it. My problem is that with this code is that i get
