private void tableLayoutPanel_Content_ControlAdded(object sender, ControlEventArgs e) {
int column = tableLayoutPanel1.GetPositionFromControl(e.Control).Column;
int row = tableLayoutPanel1.GetPositionFromControl(e.Control).Row;
if(row == 1 && column == 1) // Later i want to check it like this
}
The problem is, that the column and row are always 0, but why?
How do I bind a DATE column in a DataGridView Control to a DatePicker control (using C#)? I already have the DataGridView control bound to a database stored procedure which takes a DATE value as a parameter and selects joining table based on the results.
I have 3 columns already made Product, Price, Quantity, - what I want to do is take the textbox's txtName, txtPrice, txtQuantity, and add them to the columns in the right specific places.
This is for excel . I have a form with 2 combobox and 1 textbox ...
combo 1 : user can select a column ; let say column A combo 2 : user can select an operator ; let say = (equal) textbox : user can enter value ; let say 2
so my code is like
if (column A == tb.text) { execute code here }
but the problem i have is during run time i allow user to add more controls to the form
if ((column A == tb.text) && (column B == tb2.text)) && //may be more if user add { execute code here }
how do i handle this 'cause, how many will the user add to it, and the code should change when user add new control to it.
I am using a CEdit control as a child in a CListCtrl for purpose of making each column editable. The application is a dialog based app. My problem is... I have overwritten OnOK and OnCancel in the main dialog so the edit control never receives notifications for Escape or Enter whether in OnChar or PreTranslateMessage and I would like to delete the CEdit control after updating the CListCtrl on Enter. What can I do? I have rewritten this code many many times over the past 4 days and nothing is working.
I would like to draw a border arround a cell in a TableLayoutPanel but without also making a connection between the columns. I just want an outer border.
private void tableLayoutPanel1_CellPaint(object sender, TableLayoutCellPaintEventArgs e) { if (e.Row == 0) { e.Graphics.DrawLine(Pens.Black, e.CellBounds.Location, new Point(e.CellBounds.Right, e.CellBounds.Top)); e.Graphics.DrawLine(Pens.Black, new Point(e.CellBounds.Left, e.CellBounds.Bottom), new Point(e.CellBounds.Right, e.CellBounds.Bottom)); e.Graphics.DrawLine(Pens.Black, e.CellBounds.Location, new Point(e.CellBounds.Left, e.CellBounds.Bottom)); } }
This line
e.Graphics.DrawLine(Pens.Black, e.CellBounds.Location, new Point(e.CellBounds.Left, e.CellBounds.Bottom));
also paints connections, where i don't want them. How can i just make a outerb order arround a cell and is there a easier way to do it? Here's also an image of what i want. I don't know if i described it right.
I have researched quite extensively, experimented, and still cannot seem to change the properties of a control on an active winform from a user control.
So I have a user control which populates each dynamically added tab page in a tab control.
I have a textbox in the user control which I would like to type in, capture the text_change event, and change the text of the label in the winform.
I am writing a program that has many header files and their corresponding implementation files. I collected all the header files in a folder and did same for the implementation files into another folder. I'm using the Dev C++ IDE; I could add the files one by one to the project. Instead of doing this however, I tried adding the two folders to the project; but, the project did not compile!! The compiler could not find the files resident in each of the folders!
How I can add the folders to the project so that the internal files are visible to the compiler; or do I have to go the longer route of adding the internal files individually??
I'm trying to write a piece of code that calculates the difference in days between two manually input dates. The part of my code that's causing problems is:
xxx
When running the code and prompted to enter the date, if I input for example 31/12/2014, it'll be rejected and send me back to the beginning of the loop. Any date with 31 days involving months 1, 3, 5, 7, 8, 10 or 12 causes this problem. All other valid dates however work perfectly fine (e.g. 30/4/2014).
Something possibly worth mentioning is that, when I take out all other conditions from the loop, i.e.
xxx
it works fine (31/12/2014 is accepted), but of course I need all of the other conditions in there too.
I am new to using classes, and am running into an issue already. I have created the class, and am in the process of adding data to the classes. I have added one piece of data, and now just want to see if I can get it to show in another function, but I am not sure why it is not showing. What about getting the data to show. Then, I will be able to work on adding the rest of the info.
#include <iostream> #include <cctype> #include <stdio.h> #include <stdlib.h> using namespace std; //******************************Bill Class************************** class bill {
[Code] ....
FYI - This is only the relevant code. There is more for this that I have not added.
Error #1: error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'std::string' (or there is no acceptable conversion)
Error #2: error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'std::string' (or there is no acceptable conversion)
I'm getting an error when I want t add a file to my dataGridView that I can't add any data because it is databound. I've been working around this but still gives me the same error. heres the snippet of the code:
In my c project in code blocks , I have added another source file (KillerMoves.c) and a header file under the same name (KillerMoves.h). I added the "include guard" to prevent double inclusion. But from some reason, the program suddenly crashes with no warning or specific error. Without the new files,the program runs without any problems. This is the source .c file:
Code:
#include "KillerMoves.h" void initKillersTable(){ for(int i = 0; i < 15; i++){ killersTable[i] = -1;
I've been struggling with an object when trying to add it to a list with [Listname].push_back. You see, I have a list with some objects that will be rendered in the screen (Called objects) and a function to create a text box with some text. The function in question is the following:
(txtNum is increased then space is pressed, and when certain screen (maxScreen) have been shown, then it will go to the playing state)
My problem begins when the text box is created, because it's supposed to add only 1 text box to objects list, but instead adds hundreds of text boxes to objects.
Why is the size of an empty class 1? Why is the class still one when I add a char member to the class?//using turbo c++ 3.0, yes I know I'm using a very old c++ compiler and software
I am having some trouble creating a listbox in visual studio. I declared an array, set initial values, and now I would like to be able to update those values. It is a pizza inventory app, so I need to update the initial values once the user has added inventory. This is the code I have for the "Update Inventory" button:
// read in value and convert to double double dblInput = Convert.ToDouble(txtInput.Text); // loop through ingredients and add inventory to selected ingredient for (int i = 0; i < dblInventory.Length; i++) { // is item at i checked for update? if(lstInventory.GetItemCheckState(i) == CheckState.Checked)
How would I by any means print out the result of one number being added by two numbers 999999 times, the numbers both happen to be about 16500 digits long. It must display ALL digits in the number (all the digits the result ends up being). I know I can't use normal data-types, so what do I do?
Looks kinda like this:
for (int i = 0; i < 999999; ++i) { total += a; total += b; }
a and b being 2 different numbers with about 16500 digits.
I have an assignment where i have to make a palindrome program. As you can see i have already done the basic palindrome prog, however i am now stuck since the program goes into a infinite loop whenever a word with whitespaces is added.
I have also tried searching for methods online however they do not seem to work for me...
void CPali::check() { length = strlen(palin); for (int i = 0, p = length-1; p>i; i++, p--) { if (palin[i] == ' ')
Basically I need to make a program which asks for a business name and then keeps asking for more until user doesn't want to. Once more than 1 business is enter it should display the business and sort it alphabetically and keep displaying them each time another is added. I am lost on how to store the added business, sorting it and displaying the list.
Here is what I have so far.
#include <iostream> #include <string> #include <algorithm> #include <vector> using namespace std; int main () { string business_name; char selection;
I have tried writing a code which takes two numbers from the user and calculates their square root then the roots are added up to return the sum. The program is coming out with loads of errors.
#include<iostream> #include<cmath> float main(){ using namespace std; float m1,m2,m3,m4,m5;
Suppose I want to represent an apartment building in terms of floors and rooms with a single data object. Each floor has the same number of rooms at any given time. During the course of the program, I will need to change the number of floors occasionally and will need to change the number of rooms on each floor occasionally. (Don't worry about the building permits needed to do this.) Now, I also want to be able to iterate over either each floor (think "row") or each room (think "column"). For example, I might want to program the equivalent of "Johnson, go fix all the front doors on the 8th floor" or the equivalent of "Johnson, go fix all the front doors to room B on each floor". (Yeah, I know, for the latter I could iterate over each floor and then access room B but that doesn't feel as "clean" as being able to iterate over a separate room/column.)
