I have an HTML5 form with a number of text boxes on it. I would like these textboxes populating with data retreived from an SQL database, using inline C#. I have a stored procedure that returns the data.
View 8 Repliesi m working on a simple project, i want to populate my text boxes and comboBoxes through DataGridView, means when i double click on cell content then the text boxes are populated.my question is that if i have to populate comboBox with the specific value then what i have to do then because comboBox.selectedItem is an object but my class property is a string..
e.g
combobox shows 30 days in it and my class is Code: class account
{
public string day{set;get}
[Code]....
but that does not happen because "comboBox.selectedItem" is an object so if i have to do that what i have to do then?
I'm working on a CGI application. I'm trying to test my input with a switch statement and output the result with html tags to populate a web page. From within the switch, I've coded as follows:
HTML Code:
switch(mFunc) {
case 0:
cout << "<p><b>YOU ENTERED THE FOLLOWING TO BE CALCULATED:</b></p>" "<h2>"<< number1 <<"+" << number2 << "</h2>" << endl;
break;
case 1:
cout << "You've entered" << number1 <<"-" << number2 << "to be evaluated" << endl;
break;
I know that I'll need to put this in an html body with a content type as such:
HTML Code:
cout << "Content-type: text/html
";
cout << "<html><body>
";
Am I able to do that directly inside of the switch statement?
How you can touch a datagridview and it would insert the name it has for a product into a label or textbox.... As I have looked all over and I can't really find a proper way it is mentioned or maybe I am not applying it correctly.
View 4 Replies View RelatedI am trying to get a datagrid working in my program with populating a simple set of data. Which i can then expand on and bring in data from a database.
But even this little simple test datagrid does not seems to be working.
XAML Code
<DataGrid Grid.Row="6" Grid.Column="0" Grid.ColumnSpan="2" Margin="10" Name="DataGrid_1" ItemsSource="{Binding DataGridData}"></DataGrid>

As it is known there are nine boxes and in each box we can put numbers 1-9 without repetition. I am trying to check a given filled Sudoku puzzle whether appropriate numbers are inserted in each of the nine boxes. For the time being I don't consider row repetition and column repetition. I wrote the code using loops and condition
I used 9*9 text-boxes. The names of the textboxes is sequential like for example for the first box
txt11,txt12,txt13
txt14,txt15,txt16
txt17,txt18,txt19
Actually, I used also the controls id to access the text boxes, and each box is checking with the neighboring boxes for equality both in forward -> and backward <-

So here is the code
public void BoxCheck() {
int start = 82, end = 74;
int i, b, f;
for (int p = 1; p <= 9; p++, start -= 9, end -= 9) {
richTextBox1.AppendText("Box " + 1);
[Code] ....
This works pretty fine, but is is the right way to do it? it is efficient? Remember for a full checking I have to include row check and column check as well, this is just for checking within each of the 9 boxes in Sudoku.
I am trying to get 2 numbers from 2 textboxs and get a return sum in the third textbox. the strange thing is that i got it to work with this code that i am going to provide on the last app i worked on, now on the new app i am on it doesnt work at all.. I am not getting any Errors, just shows a zero when i calculate to the sum of the total textbox.
int sum1 = 0;
int sum2 = 0;
int result = 0;
if (int.TryParse(txtPrice.Text, out sum1) & int.TryParse(txtQuantity.Text, out sum2))
result = sum1 * sum2;
txtSubTotal.Text = result.ToString();
So I've got a button that has to use 2 textboxes to search for 2 columns in my database.
private void btnFilter_Click(object sender, EventArgs e) {
SQLiteDataAdapter adap = new SQLiteDataAdapter("select * from Test", GetConnection());
DataSet ds = new DataSet();
adap.Fill(ds);
dgvTable.DataSource = ds.Tables[0];
[Code] ....
My Current code for it.
The GetConnection(); and the CloseConnection(); Methods are just making a new connection and closing that connection, if needed I can post that code too later.
But basically, It only "filters" 1 textbox but if I say I want to search the Channel and the Log in which it is in, it doesn't search anything and returns all data in the database.
I am trying to fill a combobox using the data from a txt file, with the new line as a split.
Currently it is throwing a System.ArgumentException in mscorlib.dll
try {
string[] lineOfContents = File.ReadAllLines(Properties.Resources.departments_list);
foreach (var line in lineOfContents) {
string[] tokens = line.Split('
[Code]...
My txt list is a resource in my project.
Accounts,
Power,
Commercial,
Procurement,
HumanResources,
Plant,
IT,
Reinstatement,
HealthSafety
why this is throwing the exception?
im trying to populate a datagrid, i have a datbase class
public static List<Product> LoadProduct()

i have a product class
gettor & settors
public Product(int id, string Name, double Price, int Quantity)
{
productId = id;
productName = Name;
productUnitPrice = Price;
productQuantity = Quantity;
}
ive added the HTML code to set up the datagrid, which i can see via design tab, but filling it up is harder.
i uderstand it needs a
protected System.Data.SqlClient.SqlDataAdapter sqlDataAdapter1;
sqlDataAdapter1.Fill();// where it require a dataset or datatable
DataGridProduct.DataBind();
as it requires a datatable i converted the list to a datatable when i run it it says null, im not sure where im going wrong, i noe the list works as i tried populating on a table.
public static DataTable ToDataTable<T>(List<T> items)
{
}
i need to creat a program in la user give me "X" number and creat the textbox and y need sum all textbox
int t = Int32.Parse(txtbano.Text);
for (int i = 0; i < t; i++)
{

In my application there is a structure that holds 200 parameters for 200 tests. These structure is converted to byte array . I want to write this byte array to a file in save button and when I click open button, this file must open and write these bytes to corresponding text boxes. How it possible.?
View 1 Replies View RelatedI have a WPF grid made out of labels with two rows, Apples and Oranges currently without any information. Let's say I want to populate the grid to look like the picture below.
I was wondering what's the best way to populate the labels with a list or array? I was thinking about using a list and passing values into the list
E.g.
List <string> ApplesList = new List<string>();
ApplesList.Add("Red");
ApplesList.Add("Delicious"):
List<string> OrangesList = new List<string>();
OrangesList.Add("Orange");
etc...
But I was wondering it make sense to use a list. Or should I just use an array or 2D array?
Sometimes I wonder when would be best to use a list, array, or 2D array.
Every time the timer clicks it should show a text letter like (T) for tortoise and (H) for hare that moves around the board when the user hits go on the GUI.

I have an XML document, formatted as such:

I'd like to be able to just put all of them in ONE type of container, without making multiple lists... Is there any way, using Linq to XML, to maybe add all of these values to a Tuple?
i found somewhere online this code that populate my listbox with file names. Now is it anyhow possible to filter those names before it gets populated by regex ?
Code:
private void PopulateListBox(ListBox lsb, string Folder, string FileType)
{
DirectoryInfo dinfo = new DirectoryInfo(Folder);
FileInfo[] Files = dinfo.GetFiles(FileType);
foreach (FileInfo file in Files)
{
lsb.Items.Add(file.Name);
}
}
Call on form load:
PopulateListBox(listBox1, Application.StartupPath, "*.exe");
Now is there way to add regex for filename?
I have a window in WPF which I want the user to use to enter the information for a COM Port.
The intent is to populate two ComboBoxs from a two different ObservableCollection<string> which I am having no luck with.
I don't think that it is a DataContext issue, as I am able to get something from the ComRateList when the window opens, but nothing from BaudRateList. Either way I have included the way that the window is opened and DataContexts assigned...
When the code runs, the COM Port list is updated when the window opens - However, it is not updated when the user reclicks the ComboBox which was my intended behavour.
All the adds for the BaudRateList do not populate the ComboBox for the baud rates on start up, nor when the code is running.
When I step through the code, I can see all of the BaudRateList items being added... The window is called by the main window's datasource like so...
OpenSerialCommunication OpenView = new OpenSerialCommunication();
OpenView.Show();
This opens fine.
The OpenSerialCommunication.xaml is as follows: (Note that any business names have been replaced with [snip])

So basically I have to write a C program that, when opening the html file in a browser, looks essentially like this: (Size, position, color of the shapes doesn't matter so long as I have one of each shape and the box surrounding them. Words up top dont matter either.)
This is what I have so far:
Code:
#include <stdio.h>
#include <stdlib.h>
#define FILENAME ("A4P1.html")
[code]....
Anyways i can get the individual shapes, but I don't know how to get all the shapes to appear at once..
I am making a web browser and I have successfully made it so it shows the actual html but I want to know how to run the html within the program. I am using mac so it can't be the #include "windows.h" stuff and preferably I would like it to be cross-platform.
View 3 Replies View Relatedis this possible? How do i inject html into a process like firefox.exe or iexplore.exe? any tutorials/ starting point?
View 1 Replies View RelatedThis time I need to generate random shapes (circles, rectangles, squares, and ellipses) with random attributes with C, to html.
I am able to create specific shapes with random attributes, but I am unsure how to have the function create a random shape...
Also, the function "box" is meant to create a black border around the shapes. It does this, but I do not know how to make it so that the other shapes do not show up along the lines of this "box."
I guess it appears that certain shapes are "layered" over top of others? ie. My circles/ellipses always show up on top of the rects/squares/box.Currently I have this:
Code:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define NO_SHAPES 10
#define X_RANGE 797
#define Y_RANGE 397
