I am working on a drink machine simulation. I have a text file that holds the prices, names and inventory. My problem is It won't let me set my prices at 1.00 or higher. Ex: I set the price to 1.50 in the text file then when it reads the info and stores the price it only stores .50 instead of 1.50.

textfile looks like this: Apple Juice 1.50 20 Mango Juice 1.50 20 Sprite Mix 1.90 20 Coca Cola 1.90 20
I have a datagridview with many columns. I want a context menu to show up when user right-clicks on the fifth column (column index = 4).
private void dgv_CellMouseClick(object sender, DataGridViewCellMouseEventArgs e) { if (e.Button == MouseButtons.Right) { DataGridView.HitTestInfo hit = dgv.HitTest(e.X, e.Y); if (hit.ColumnIndex == 4) { contextMenuStrip1.Show(Cursor.Position); } } }
The problem is, the hit.ColumnIndex value is either 0, -1 or 1, no matter where I click. So the condition never met and the context menu never shows up. Why the values 0, -1 or 1?
I am developing a CFormView MFC app. When I go to click something on the menu, it takes awhile before the event happens. The project is build optimized in release mode. I have 3 additional threads and I thought they might be blocking the internal MFC framework stuff, but I use the Sleep() call in each thread to yield to the MFC main app.
I derived a class from CRecentFileList in order to set the number of displayed chars for MRU.
The problem is that if I open the app with 256 set for this number (it is read from .ini file) the display is correct. But after I change it to 10 for e.g., File menu width remains unchanged altghough MRU are correctly displayed on 10 (or at least file name lenghts) chars.
how can I tell to the menu to shrink to actual width?
I have problem reading CSV file, i found many solutions but i still got one problem. I need to read CSV file and then these values show in List Control and here i have problem. Idk how to display it in List?
I have a (large) application that works perfectly under XP. When I run it under Windows 7 the "File Edit View..." menu in my application flickers when everything is otherwise idle.
I have traced this down to SetTimer and its associated OnTimer function. OnTimer usually does nothing, so I have commented out everything leaving this:
Code: void MyView::OnTimer(UINT nIDEvent) { }
I have also changed the SetTimer call to give one tick every five seconds.
I now see the same behaviour: the File menu is very briefly greyed-out every five seconds, leading to the flicker. Nothing else in the window is exhibiting this flicker.
So, I have a call to a null function every five seconds that manages to affect a menu.
I have two menu items. When item 1 is disabled, I want item 2 to be disabled as well. In the OnUpdate handler of menu item 1, I have tried to use "t_pMenu = pCmdUI->m_pMenu;", "t_pMenu = pCmdUI->m_pSubMenu;" and "t_pMenu = pCmdUI->m_pParentMenu;" but I always get NULL t_pMenu. How can I achieve this purpose?
when ending my app in the debugger, memory leaks will be shown like this:
Detected memory leaks!
Dumping objects -> C:PROGRAM FILESVISUAL STUDIOMyProjectsleaktestleaktest.cpp(20) : {18} normal block at 0x00780E80, 64 bytes long. Data: < > CD CD CD CD CD CD CD CD CD CD CD CD CD CD CD CD Object dump complete.
How can I tell Visual c++ also to show me the memory leaks in a called dll?
I am trying to write a menu program that will be broken down into a series of calls to function for each of the menu items. Two of the menu items will be simple programs which I wrote.
I want two of the functions to run one of the two programs I am trying to include as items in the menu.
So far I am only familiar with variables, loops, if statements, and I just learned how to write functions.
The problem I am have is that I don't quite understand how to write a function that will run one of the two programs. Also I am having a hard time writing the program in away that would allow the user to select the menu items.
I'm creating a program that is based on a menu system. Basically each menu is its own user-defined function. The problem is at each menu you can input 'b' to go to the previous menu. I just have it call the function of that menu.
However, do the functions need to complete themselves eventually? If I just keep calling functions will I just keep going further and further deeper into ever running functions?
If so how do I avoid this and yet keep the option to go back to a previous menu/function?
I'm using this tutorial for making an owner draw menu. [URL] ...
When I go into the .rc file and remove all of the MENUITEM SEPARATORs all the menu options are squished to the left of the menu as in the screenshot. As long as there is just one MENU SEPARATOR anywhere the menu is fine. If I could make the application without MENU SEPARATORs that would be awesome.
I have been told to show some text document when our application starts up, it is an EULA. They gave me a word file and I saved this file in a .rtf format. I then wish to show this in a dialog box and found this on code guru: [URL]
Which seems to be a sub-class that will do all the formatting for me. So I use that class and then load in the .rtf file, using their setRTF method I just get an empty text box.
I just want to be able to show this formatted, somewhat pretty text from this document in my application as close as I can to the original document. Is there an easy way to do that? I could turn it into plain text, but I think that my boss would not be happy about that.
The problem was that I needed the text box to be marked multi-line.
I want create menu button to change font of CString displyed in main window. We can see string "SAMPLE",and when i press menu button that i created i want to string "SAMPLE" to display with different font,i already created CFont object and added italic style with CreateFont;
This is my menu function:and CString m_text and CFont font1 are declared in FesbDoc.h
I quite often use an ide written in assembler: RadAsm3[URL] .....
It has a menu item to explore current path. I have used other ide's that have a similar feature but:
The one in RadAsm3 will activate a current Explorer window if the current path is the same as the one requested. All others open a new Explorer window.
I would like to implement the RadAsm3 approach using Visual Studio 2013 Community c++ as my host compiler for testing.
I tried to get the title of current windows but it appears ShellExecute "explore" does not produce a conventional window???
I am writing a employee payroll program using structures. My program is running but its only showing some of the data.
HERES MY CODE
Code: #include <iostream> #include <cstdio> #include <fstream> #include <string> #include <iomanip> #include <cstring> using namespace std; const int SZ = 20; // size of arrays to hold scores struct payrollStruct {
[Code] ....
And it doesn't show anything from txt file
Code: 40.0 10.00 A1234 Jane Adams 50.0 10.00 L8765 Mary Lincoln 25.5 10.85 W7654 Martha Washington 52.0 15.75 A9876 John Adams 45.0 25.00 W1235 George Washington
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);
