I have a question, is it possible to Concatenate a variable to a label?
For example, i'm doing:
Random Rnd = new Random();
int num1 = Rnd.Next(1, 11);
And now i want to concatenate the random number to give test me if the label of that number has a char inside.
if ( lbl_s_num1.Text != "X")
today deals with using a two window option to view entered data. I have the GUI set up for my user entry, but am not sure how to get that information to save into a datagrid on another page. I have inputboxes for First Name, Last Name, and Phone Number; a combobox for an occupation; and lastly a radiobutton for Gender. I am trying to teach myself how to get this information to save to the other page so that when you click submit you automatically go to the next page to view your entered data.

I would like for it to use a tile sheet from the user which they then can click on tiles from it and place it on the specified grid. Then export this as a binary file. Or perhaps it would be easier for the user to chose the grid size then have each grid space's number be able to be changed like 01,02,03 to represent an image. Then export this as a binary.
View 1 Replies View RelatedI have written a long console app (over 1000 lines of code) and I want it to have a GUI. I was wondering if there was a way to quickly convert it to Winforms or other GUI?
I already know how to include Winforms to a console app. But when I compile it, the Winforms does not include the Console app component of the program. My Form.cs includes the Winforms and Program.cs is the console app part with >1000 lines of code that I wrote before. Compiling it, only the part in the Form.cs runs. The Program.cs part doesn't run. For example, I have many "Console.Writeline" and "Console.Readline" parts in the Program.cs, but they run after I add the "Form.cs" to the program
Although the Form.cs runs, the Form.cs [design] doesn't show up
Why it's not working and how to make it work?

I am trying to create an application interface serial data reception using c #. I send the data from the serial adc microcontroller adc atmega 16 ... the data is 0 to 1023. In the textbox that I use as a data reception, data updates to the bottom if I use ReadLine coding.
examples:
1023
1023
1023
256
669
If I use ReadExisting, the data displayed by the textbox moves to the side. examples 102310231023256669
When the data changes from 0-1023 of serial communication, and clear the data will store in otomatiis in the textbox.
When there is reception of data with a value of 1023 and immediately there is a change to the value of 555 textbox value will not store the value of 1023, I want the value in 1023 immediately deleted automatically and change the value to 555 when a change in the value of the data ...

I'm working on a personal project, where I have a database (SQLite) and a dataGridView. Now This is what I have:

SqlDataAdapter SQLda = new SqlDataAdapter("Select * from User", connection);
SqlCommandBuilder SQLcb = new SqlCommandBuilder(SQLda);
dataGridView1.Fill(ds, "User"); //Error here
dataGridView1.DataSource = ds;
dataGridView1.DataMember = "User";

I have been assigned the following task and I am having difficulty in getting it to compile. The compiler is stopping at line 27 but I don't no what the error is.
The task is as follows:
Write two functions with the following function prototypes:
int my string len(char str[])
void my string cat(char dest[], char src[], int dest size)
Both functions should take zero-terminated strings as input. The first function should return the length of the string to the calling function. The second function should take a source and a destination string and the total size of the array pointed to by dest. It should then concatenated the source string onto the end of the destination string, if and only if the destination string has the capacity to store both strings. If the destination string does not have the capacity it should not alter either, print and error, and return to the calling function. Demonstrate the use both the above functions by using them in a program in which you initialise two character arrays with two strings, print out their length, print out the combined length, and print out the combined string
And this is my code so far:
/* A program to demonstrate string concatenation */
#include <iostream>
#include <string.h>
using namespace std;
int my_string_len(char str[]){ // function to calculate length of a chracter array
int len = 0;

I am stuck on my program right now, what i am trying to do is get the sum of the amount from a access database table and than display it on a label, however i cant seem to get this to happen. This is what I have so far:

conn.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Church.accdb";
conn.Open();
Form1 frm1 = new Form1();
//frm1.Show();
//string tableName = frm1.tableName;
//string time = "4/5/1991";

I'm trying to print numbers in a label but I'm not having success. For example, I have the following code:
private: System::Void txtLeftWheel_Click_1(System::Object^ sender, System::EventArgs^ e)
{
for (int i = 1; i <= 1000; i++)
{
Sleep(100);
this->lblLeftWheel->Text = (Int32::Parse(this->lblLeftWheel->Text) + i).ToString();
}
}
The idea is that when I click the button, the numbers on the label increment from 1 to 1000.
The Sleep() is there to slow down the loop and the user can see something happening. However, if I put the Sleep() before the label->, the form freezes completely. If I put the Sleep() after the label-> text, the form freezes for a few seconds and the label text goes from 1 and jumps straight to 1000.
The expected functionality is that the label displays numbers 1 through 1000 but increment every second.
I have a label on my main form. When I menu select my settings form, I make a change to the label text on the main form but the label text does not update with the new text.
So here is my code in my settings form:
MainForm frm = new MainForm();
frm.paintMainFormThemeTitle(logoText); // updates the main form label
I may not fully understand the new instantiate key word, but doesn't this create another, new copy of my main form to operate on? And isn't that why I can't see my label text change on my main form that is previously in view?
All of the examples that I have been able to find show using this new key word to be able to access a component on another form. But to my understanding, I'm creating another, new form.
In my program I have WinForm and on this WinForm I have a User Control. On the User Control I have a TreeView.
So what I'm trying to do is passing a number, which is in the TreeNode Text to the WinForm. On the Winform I have a couple of Labels which I want to fill with Informations. To get those informations I have a class with a method which Needs my number from the User Controller. But I can not Access the Labels in the WinForm Method.
Here my code:
User Control
private void TreeView_SelectedNode(object sender, TreeViewEventArgs e) {
CwiaMain frmMain = new CwiaMain(TFS, TfsConnect);
TreeNode tn = _tvWorkItemList.SelectedNode;
if (tn == null) {
MessageBox.Show("Error");

My program has a goto label in it and when the program is not instructed to goto the label, it does. When control goes to the line that it is on, even if no where does it say to execute the label's content, it does execute it.
