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 wish to add the item 'Website' to an MFC Dialog app System Menu so that it can activate the following method:
Code:
void CMyDlg::OnWebpage()
{
ShellExecute( NULL, NULL, _T("[URL]..."), NULL, NULL, 0 );
}// OnWebpage()
I have tried this:
Code:
#define IDM_WEBSITE (WM_USER + 101)
//..
if (!strAboutMenu.IsEmpty())
{
pSysMenu->AppendMenu(MF_SEPARATOR);
pSysMenu->AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);
pSysMenu->AppendMenuW(MF_STRING, IDM_WEBSITE, _T("Website"));
}
[Code]...
The code compiles without error but and the 'website' item appears on the System Menu but it doesnt do anything.
I've inspected the following but don't really understand how it works and it seems to me there should be a simpler way to accomplish my end.
Modifying the System Menu By John Simmons 26 Jan 2007 [URL]....
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.
View 7 Replies View RelatedI have an MDI application using different menus depending on the current document template in use.
I need to show the top-level File Menu from the IDR_MAINFRAME window when a command is sent from the active document.
I would like to application to deactivate the active child window and then show the File menu as if the alt-F key was pressed from the keyboard.
I have tried CMenu *pMenu=AfxGetMainWnd()->GetMenu();
but this does not display the menu at all.
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.
what may be causing this?
If I get a bitmap from the clipboard with:
hBitmap=(HBITMAP)GetClipboardData(CF_BITMAP);
...how do I get the width and height ? Can I get at the BITMAPINFO ?
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?

I m trying to load a png image by giving the dimension of my own.
CImage Image;
Image.Load (L"D:ImagesPNG_ImagesImage7.png");
But here what happens is that I m not able to give my own dimensions.My code requires constant changing of dimensions of the image.
I tried using libpng.lib in my code.But I dono the keywords for loading the png image after including the lib.
I m using Visual Studio 2010. I m developing in vc++.
How do I load and change the height and width of a png image?
All i want to do is modify a header of a file(.exe file). I just want to do if for fun and see what I can do with it.
View 3 Replies View RelatedMy problem is that I have to modify only some specific details in a txt file (actually it is a wrl file but it can be considered as a txt file). There is a lot of text there but I just need to modify the point coordinates and leave the rest of the text as it is. Reading the "sample file" at some stage we will see some blocks that look like the below:
coord Coordinate {
point [
# bottom
-1.0 -1.0 1.0, #vertex 0
1.0 -1.0 1.0, #vertex 1
[Code] ....
where the numbers are (X,Y,Z) coordinates. What I have to do is to change those figures for (X,0,sqrt(X^2+Z^2)) points. Therefore the expected result (test file) will be as follows:
coord Coordinate {
point [
# bottom
-1.0 0.0 1.4142, #vertex 0
1.0 0.0 1.4142, #vertex 1
[Code] .....
So in my opinion it can be good to have two files: sample.txt and test.txt where the sample file will never be modified whereas the test.txt will be the same as sample.txt but including the modifications as explained above. The idea can be to read the sample.txt, store the info and then start copying each line in the test file until we get to the points coordinates (which needs to be modified) and continuying with this process until the next set of coordinates.
The problem is that I do not know how to change x,y,z coordinates from the sample.txt to (X,0,sqrt(X^2+Z^2)) and to copy them in the test.txt. Please see some code below and the sample.txt file attached.

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?
Normally, menu bar resides below the title bar. See attachment MenuBarOriginal.JPG
Is there a way that we can position the menu bar? For example,place it on the side or anywhere on the dialog box?
MenuBarModified.JPG is some sample of menu bar positions that I want to place.
I want to do this on a dialog box.
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.
Can change the menu bar font size in CMainFrame::OnCreate()? Here's what I have:
Code:
int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct) {
CRect rect;
GetClientRect(&rect);
if (CFrameWnd::OnCreate(lpCreateStruct) == -1) {
return -1;
[Code] ....
The line "m_wndToolBar.SetFont(&m_font);" does nothing.
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
ON_COMMAND(ID_EDIT_FONT, &CFesbView::OnEditFont)
void CFesbView::OnEditFont() {
CFesbDoc* pDoc = GetDocument();

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???
This is what I have so far, it gives me a nice menu to select from and it all works but after I make a selection it closes the program. I tried to return to it but it won't work for me

int choice;
int deposit;
int balance = 500; {

I'm attaching a project that demonstrates the issue. I need to display a context menu with anti-aliased bitmaps. I wrote my own method to convert an icon into a bitmap (see the CreatePARGBBitmapFromIcon() method) but the resulting bitmap seems to lose all anti-aliasing when displayed in a menu. What is interesting is that the same bitmap is displayed without any issues in a CStatic 'stPic1' control (the one in the middle.) The visual artifact also seems to be different on different OS. Take a look at the screenshots attached.
View 1 Replies View RelatedI was reading a c++ code written in embarcadero ide to add vertical colour text in popup menu.
While reading the code, I had seen following instructions.
private:
Code:
void __fastcall ExpandMenuItemWidth(TObject *Sender, TCanvas *ACanvas,int &Width, int &Height);
Code:
void __fastcall DrawNewItem(TObject *Sender, TCanvas *ACanvas, const TRect &ARect, bool Selected);
The above two methods used in the code like below:

My problem is ToolTips are not shown if any of the tool-bar menu items is disabled/inactive.

It said my width1 is being used wihtout being initialized.. what does it mean?
#include<iostream>
using namespace std;
double Area(double height, double width);
double Perimeter(double height, double width, double height1, double width1);
[Code] .....
I am currently debugging this function. I am trying to make this function's width specifier align like a printf() routine. Here 's the code:
v Code:
oid
bu_log(const char *fmt, ...) {
va_list ap;
struct bu_vls output = BU_VLS_INIT_ZERO;
if (UNLIKELY(!fmt || strlen(fmt) == 0)) {
bu_vls_free(&output);
[Code] ....
Basically when I type in different widths and heights for the col and rows, the buttons that make up the width get cut off. Something is messed up but I'm not sure what!
InitializeComponent();
int _col = int.Parse(cols);
int _row = int.Parse(rows);
int width = groupBox1.Width;
int height = groupBox1.Height;
int bW = width / _col;
int bH = height / _row;
[Code] ....
The program is when a person clicks a button this button updates 2 separate listbox one tracks the total rolls the other displays the total amounts of frequency afterwards adjusting labels as a scaling measurement.
The problem I am having is right at the end where I am trying to adjust the width of the label this is what I have. It is highlighting the word "Items" for each label and says that Non-Invokable member 'System.Windows.Forms.ListBox.Items' Cannot be used like a method L2 is a label. Additionally I have added in the information for one of my loops below the line I am having trouble with this loop is created to determine how many lines are in the listbox of rolls and I have no trouble with this just thought id add it for additional information I dont think I need to add the rest of the code but I can if needed.
L2.Width = int.Parse(lstfrequency.Items(0).ToString());
TL = 0;
for (I = 0; I <= 10; I++)
{
TL += int.Parse(lstfrequency.Items[I].ToString());
}
lstfrequency.Items.Add(TL);
The problem says:
Define functions n(), s(), e(), w(), center(), ne(), se(), sw() and nw(). Each takes a Rectangle argument and returns a Point. These functions define connection points on and in the rectangle. For example, nw® is the northwest (top-left corner) of a rectangle called r.
I wrote below code for that:
#include <Simple_window.h>
Point n(const Graph_lib::Rectangle& r);
Point s(const Graph_lib::Rectangle& r);
Point e(const Graph_lib::Rectangle& r);
Point w(const Graph_lib::Rectangle& r);
Point ne(const Graph_lib::Rectangle& r);
Point se(const Graph_lib::Rectangle& r);
[Code]...
As you see, this just mark the top-left corner of the rectangle r. In other functions I need the specifications of that rectangle, for example its height and width. How to use these specs in those functions?
