Visual C++ :: How To Scroll Text Drawn With DrawText
Apr 16, 2013
I have an emulation project I've been working for a long time (the Altair32 Altair/IMSAI emulator) and I'm trying to simulate a dot-matrix printer for list output in CP/M.
Here's what I have so far and where I'm stuck and need a push in the right direction. I'm using a dialog box with a green bar paper bitmap as the client area background. I used CreateFont to load a dot matrix printer TrueType font and have the base code to print on subsequent lines. So, based on the dialog size, font size, etc., I get about 10 lines of dot matrix printing, 80-characters wide. So far so good.
The problem arises in how do I scroll the text like on a printer? I thought about trying a static text control or an edit box, but the text to be printed is of an unknown size and ISTR that both of those controls have finite size limits (32k but maybe I'm wrong). They would also need to be transparent so that the green bar paper shows through.
For a ribbon bar with edit controls (CMFCRibbonEdit) I want to handle the mouse scroll events for the edit controls. That is, when the user clicks and then scrolls on the edit it will navigate a predefined list of strings. I want to capture the scroll event in order to update the edit text step by step.
This kind of behavior is implemented by the Spin Edit; I don't want to use the spin edit control since it only uses a list of integers and the spin buttons are too small.
Is there a way to catch the mouse scroll event for the CMFCRibbonEdit control? How to approach message handling for the ribbon (other messages than the COMMAND allowed by the ribbon designer). I'm using VS2010 on Windows 7 and the ribbon was designed with the ribbon designer?
I have some code that will allow me to draw a crescent moon shape, and have extracted the values to excel to be drawn. However in place of some numbers, there is '-1.#IND' in place.
Is there any methods to add scroll bar for group box
My code scenerio is: I have many groupbox in form, all group box will be appears in same place and also height and width is fixed. I'm doing group box visible true/false according to condition.
So some groupbox ecxeeds the width and heighto so I want to put this all in scroll Bar
I want to show my output in one line. But my output breaks to next line even before endl is encountered.code blocks horizontal scroll bar in console? is it c++ formatting issue or console issue?
I am working on a 2D side scroller game. Where a ball is moving continuously towards right . I used a camera to follow the ball as soon as ball reaches the center of screen. I created a horizontal line to look like the surface on which the ball is rolling.
line runs from x=0 to x=800 (i.e screen width)
NOTE: (0,0) coordinate is at top left corner of display.
Problem: My display is 800 x 400 . Camera follows the ball, but soon the ball crosses x=800 and starts moving in black background. I want that line surface to stay there instead of going out of bound.
Additionally! I generated obstacles from x=800 which also move out of bound along with my line.
What should be done here? This is just my first c++ game project, so i might be skipping things that can solve the issue.
[Update] these screenshots manage to show, what the real problem is: [URL]
im trying to code a simple list box for my self made GUI but i seem to be stuck at the scroll bar. I already finished with the calculation for the scroll bar size but how I could calculate it's current vertical position depending on the current item on top of the list box.
My current code looks like this
ListBox struct: struct MenuListBox { int PosX; int PosY; int Width; int ItemsVisible; //Items visible at the same time int CurrentItem;
I can't seem to make IE selected text draggable into my MFC application. Take a look at the sample VS 2008 C++ solution attached. To illustrate, compile and open the app. Then open an IE (the one I'm using is IE 9 version 9.0.8112, update versions 9.0.12), select any text in it and drag it into the app's text box. It won't let you. But if you try it with practically any other web browser (Chrome, FF) it works just fine. Why can't I make it work with IE?
I'm trying to create a dialog where some of the buttons have pictures on them, rather than plain text. I notice that under the button's properties, under the "styles" tab there's a checkbox "bitmap". I can't seem to find any easy way of setting a bitmap.
I'm making a very first program. It's very little more then a simplistic calculator, but i'm having a problem with the cout function. It won't display any text what could the reasons be?
#include <iostream> #include <string> #include <sstream> using namespacestd; int main () { do { int(a);
[Code]...
Oh and i'm aware it's still riddled with numerous problems, I just have been working on the cout thing first.
Now I got rid off the white border but everytime I draw a text it write on top of the previous text so after few seconds everything is a mess and the time is no longer readable.
I am trying to change the text hue in this gump, i have made most the changes but cant figure out these two errors?
Errors virtuestatusgump.cs:cs1002: line 75, column 32) ; expected virtuestatusgump.cs:cs1002: line 75, column 32) identifier expected
Code: case 1: { m_Beholder.SendGump String.Format( new VirtueInfoGump( m_Beholder, "Humility", "Humility is perceiving one's place in the world, not according to one's own accomplishments, but according to the intrinsic value of all individuals. One gains Humility through supporting young players.", m_Beholder.Virtues.Humility ) ); break; }
And here is the full script.
Code: using System; using Server; using Server.Gumps; using Server.Network; namespace Server { public class VirtueStatusGump : Gump
I'm currently making a math program in c++ windows form application. I'm trying to make it so where the user presses the number button I such as 1 button to display a 1 in my textbox.
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.
The user will first enter the file name to be processed. The program can do the following 5 tasks:
1. Count the number of words 2. Count the number of alphabets (without punctuation marks) 3. Count number of sentences. 4. Count the frequency of each vowel. 5. Count frequency of the following three words individually: FAST, computer and engineering
There should be a proper menu through which the user can select the desired task. The program should continue until the user asks to terminate it.
Here is what i have done so far:
#include <iostream> #include <cstring> #include <fstream> #include <cstdlib> using namespace std; int main(void) { int opt=0; //option number ifstream fin; string filename;
[Code]...
There are a few problems.
1- When I enter option 'q', an infinite loop starts. 2- The first time, the program gives the correct value. After that, each time it gives answer ZERO. 3- The last part is not working. I experimented something which failed. I don't know how to do the last part.
I have a tabbed dialog with a couple of Separate dialogs. I created classes of CDialog for each dialog. Im trying to get the text from the edit control from the tabbed dialog and it appears in a message box when I press a button on the main dialog.
Code: myDialog test; test.UpdateData(TRUE); CString bla = test.m_edit1; test.UpdateData(FALSE); MessageBox(bla,bla,MB_OK);
The m_edit is a variable of CString for the edit box
it gives me a error and crashes.
How do I get the text from the other dialogs edit control?
I am doing an exercise that reads in a text file and loads the data into a struct. My problem is it doesn't read anything from the text file. I think it's the way I'm loading the data. Oh, it does read in the first record that tells the program how many contributor records to create, but nothing after that. Here it is:
Code: // #include <iostream> #include <fstream> #include <cstdlib> const int strsize = 30; const int SIZE = 60;
