I'm working on a personal project, where I have a database (SQLite) and a dataGridView. Now This is what I have:
public Form1() {
DataSet ds = new DataSet();
SqlConnection connection = new SqlConnection(@"Data Source=testingsql2.s3db");
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've marked where I get the error.
And the Error description:
Error 1 'System.Windows.Forms.DataGridView' does not contain a definition for 'Fill' and no extension method
'Fill' accepting a first argument of type 'System.Windows.Forms.DataGridView' could be found
(are you missing a using directive or an assembly reference?)
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 want to create a simple map editor in winforms. 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.
I 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
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 ...

Here is my source code i am trying to write a function (fillAll) to fill all 52 cards in a deck and i would like to use my data struct for the function and make Deck one of my parameters.
so im trying to make a background for a menu, but it is only so big. its not the kind of picture where i can just reapply it. is there a function to make it fill to the screen?
So this is my working code with sql i want convert it so i can read it from xml, basiccl i need to fill empty list with xml column BrivDat..
var connStr = @"Data Source=(LocalDB)v11.0;" + @"AttachDbFilename=C:dbaseAdaPlus.mdf;Integrated Security=True"; List<DateTime> Holidays = new List<DateTime>(); using (SqlConnection conn = new SqlConnection(connStr)) using (SqlCommand cmdd = new SqlCommand("select * from Brivdienas", conn))
I am using koolplot plot graph and able to plot two lines in a graph. My question is how to fill between the lines? Is it possible to do so with koolplot? or i should use another library?
Write a menu driven program that will fill grid with values between 1 and 100. Begin the program by declaring a array of type int. Then present the user with the following menu
Enter 1 to add Enter 2 to edit Enter 3 to delete Enter 4 to search Enter 5 to display Enter 0 to Quit
Each item of the menu must be implemented as a function. The program should Only allow values between 1 and 100
Always ask the user to apply coordinates for the cell to be changed
Flag an error when try to delete or edit a cell with a zero (0)
Flag an error when try to add to a cell that is not blank
Display the complete and nicely formatted grid when option 5 is selected
I installed FLTK 1.3.X (from here [URL] ...) on my visual studio 2012 compiler and use PPP book for programming (this: [URL] ..... ). My problem is about filling a Shape in. For example , this code:
#include <Simple_window.h> using namespace Graph_lib; int main() { Simple_window win(Point(100,100), 1000, 600, "Binary_tree"); Graph_lib::Circle c(Point(200,200),50); c.set_color(Color::red);
[Code] ....
When I run the program, All three Shapes are drawn but only the Rectangle is filled in! Why?
set_color works for the three and apparently the set_fill_color is defined for all Shapes and it too should work but why it doesn't work for Circle and Ellipse?
I'm trying to make a character array, and be able to custom fill it by using the scanf() function to ask the user for each character spot in the array.
Code: #include <stdio.h> int main() { int i; char character_array[11]; char *charpointer; charpointer = character_array;
[Code] .....
And this is the output i get when i run it:
Code: root@kali-Tulips:~# ./myown what letter would you like in the [0] spot of the array? : a what letter would you like in the [1] spot of the array? : what letter would you like in the [2] spot of the array? : b what letter would you like in the [3] spot of the array? : what letter would you like in the [4] spot of the array? :

Obviously I'm trying to grasp C programming and am very new. I don't understand why this isn't working, and i think its more than my lack of knowledge of C syntax. I believe the correct memory is allocated but when examined with gdb i don't find what i expect....
I'm in need of an algorithm to find the points within a triangle(vertices are known. 3d coordinates). The points are to be at same distance from one another i.e. the points are uniformly distributed within the triangle.
I have done a search about the topic and have come across some ideas like lattice points generation ,tiling polygons with Lattice triangles [URL] .... and taking their centroids as the points.
This code is for a member function called Triangle. It's a Draw() function that uses border characters and fill characters. I've been trying to work it out in a seperate file just so I can get it to work before I add it to my function definition.
#include <iostream> using namespace std; int main() { for(int i=1; i<=8; i++) { for(int sp=1; sp<=8-i; sp++) {
[code]....
I haven't attempted the fill characters (well... I have, but it was so wrong it was ridiculous). I need to get rid of the extra '*' at the very top. Here's an example of what this should look like...
I am an IT student currently learning linked list. I have a problem with my code here. After I call addFront() my list doesn't change when I display it. How do I somewhat change/fill my list without changing the function type? I know it works on pointers still messed up with linked list.
Is it possible to fill a textbox on a webpage using the onkeydown html element in c# using the web control built in. i am totally aware of the normal methods of doing this but the normal methods have failed to work....
#include <iostream> #include <fstream> #include <cstdlib> #include <ctime> using namespace std; int main () { ofstream fout("datain.txt",ios::out); int array[6][6];
When I remove the BeginPath() and EndPath() functions my lines are being drawn. But when I insert this BeginPath() and EndPath() and StrokeAndFillPath(hDC); the nothing is being drawn.
Why it is not doing as per the expectations. I want to draw a shape for example A with a outline. And i want it to be closed when drawing is ended and filled the hollow portion.
What am I doing wrong in this ?I am not implementing it in WM_PAINT but drawing is done in WM_LBUTTONUP.
The code below is supposed to fill, show, and revalue property. The fill function is supposed to return a pointer that creates a range of property values. The show function is supposed to show the property values entered and the revalued property values. I think part of the problem is the returned pointer from the fill function. Once that is cleared up, I think I will find more problems.
Code:
#include <iostream> const int Max = 5; // function prototypes double fill_array(double ar[], int limit); void show_array(double * begin, double * end);

I read that Memory is allocated during definition of a variable and not during declaration. Declaration is something like,
Code: int x;
And definition is assigning some value to it. This is what my professor taught. My doubt is if memory is not allocated during declaration, then how the compiler successfully compiles and runs the following, which i had already tried.
Code: #include<stdio.h> #include<conio.h> int main() { int c; int *p=&c; printf("%x",p); getch(); return 0; }
The variable c is only declared. But the program outputs a memory address. Shouldn't it show an error?
