Visual C++ :: MFC GUI-setting COMPort And Read Hex Data From Pic (ASCII)
May 22, 2014
I want to setup my MFC-based dialogue "IDD_LOADCELL" with serial communication so that when that dialogue is pop up, the data from PIC (external device) which is in hex file format is display on the edit control box on the dialogue. The variable name of the edit control box is "m_loadP "and "m_loadT1". type of variable for both are string. I want to get the code for the COMPort setting and reading the data from pic and finally display it on the edit control box created on the dialogue.

I'm writing a program that reads and counts all the printable characters (ASCII 32-126)found in a text file.
For example if the text file read: Why so serious?
The output to the screen would display(in order of ascii value however):
Character-----Total
W--------------1
h--------------1
y--------------1
s--------------3
o--------------2
etc...
However, I don't think it's reading any of the characters.
#include <iostream>
#include <iomanip>
#include <fstream>
#include <cmath>
#include <string>
using namespace std;
int main() {
int i, count[127];

This is a small program that reads a line from the screen, takes the ASCII values from the entered text, and edits it. Next, the ASCII values are reinterpreted (am i misspelling?) as text, and displayed. However, my final output has (allways?) at least 7 characters, even if you enter only one. I'm also trying to accomplish, that the part of the string which isn't filled, will be printed empty. In spaces.
compiled with -std=c99.
Code:
#include <stdio.h>
int main(){
int maxsize;
printf("How long is your message?

I'm new to programming and i'm trying to do a certain task. I want to use a for loop to read certain data from a txt file and print them to a console. I'm trying to read student names and their grades.
Something like
3 // 3 represents the number of students.
George 97
Sarah 70
Maya 88
The data may vary but it's always in this format.

I want to send data from a laptop (windows 7, processor 2.60GHz) to a desktop (windows xp, processor 3.10GHz) using serial communication (using a USB to RS232 convertor). The WriteFile function is able to send the data from the laptop (NumberOfBytesWritten is correct). But on the desktop side, ClearCommError detects no data in the read buffer.
This is the relevant code in my desktop:
while(1) {
ClearCommError(hPort,&dwErrors,&commStatus);
if (commStatus.cbInQue != 0) ReadFile(hPort,&data,1,&dwBytesRead,NULL);
Sleep(10);
}
The if condition is never satisfied. The baudrate and other parameters in the DCB struct are the same on both sides.
The same code works when I write and read in the same system by shorting the RX and TX pins in the RS232 connector.

I have a MFC dialog project, I move all the icons including the IDR_MAINFRAME icon into a resource-only DLL, so there is no icon embedded in the executable file. In the dialog initialization, the dialog loads the icons using LoadIcon(hResdll, MAKEINTRESOURCE(IDI_MYICON))). The icons shows correctly on the dialog.
But in the Windows Explorer, the icon of the .exe file is not the icon of IDR_MAINFRAME, I check the resource file in the resource-only dll project, the ID number of the IDR_MAINFRAME is the lowest one of all icon ID numbers. I also try
Code:
SetClassLongPtr(m_hWnd, GCLP_HICON, (LONG)LoadIcon(hResdll, MAKEINTRESOURCE(IDR_MAINFRAME)));
But it doesn't work. The IDR_MAINFRAME icon doesn't show in the Explorer window, the system provides a default icon for the .exe file.

pSliderCtrl->SetRange(1, 100); // ok no problems
Now, how to "move" btw. how to redraw the position of the slider thumb programmaticaliy with c++? Need to send some message, if yes what message i need to send to slider control to move (reposition) the slider thumb?

I believe I set up everything correctly. I linked the library folder, the includes, and included the libraries needed. It still comes up with an error that it can't find the functions or something like that.
The error:
Do I need to include the DLL some way? I tried adding it to the build directory and the EXE directory, but it did not work. My code is just a small test.
#include <GLFW/glfw3.h>
#include <cstdio>

My MDI Project(VC++2010 Professional) is unable to catch errors ,though I return ,try catch block. So I developed simple dialog based application .Placed one button on Dialog and on its click written following code
Collapse | Copy Code
void CMFCExecDlg::OnBnClickedButton1() {
try {
int j = 0;
int i = 10/j;
}
catch(CException * e) {
MessageBox(_T("Hello"),_T(""),MB_OK);
}
}
But still program control does not come in catch block it simply gives error. I tried all child classes of CException but no use.I think there will be some setting in Visual Studio. How to handle exceptions

I am using PDF Creator printer to print my files. I have set it as default printer. It displays two dialogs .. "Printer Setup Dialog" and "Dialog asking filename and other details to save to file".
I want to avoid these two dialogs. But EndDoc calls the other dialog by default. How to do this ?

I am writing a program where I need to read a byte of char data and convert it into a text string of binary data that represents the hex value...
i.e. The char byte is 0x42 so I need a string that has 01000010 in it. I've written the following subroutine....
------------- My Subroutine ----------------------------------------------------------------------
void charbytetostring(char input, char *output){
int i, remainder;
char BASE=0x2;
int DIGITS=8;
char digitsArray[3] = "01";
[Code] ....
When I submitted the byte 0x42 to the subroutine, the subroutine returned to the output variable 01000010... Life is good.
The next byte that came in was 0x91. When I submit this to the subroutine I get garbage out.
I am using a debugger and stepped through the subroutine a line at a time. When I feed it 0x42 I get what I expect for all variables at all points in the execution.
When I submit 0x91 When the line remainder = input % BASE; gets executed the remainder variable gets set to 0xFFFF (I expected 1). Also, when the next line gets executed..
input = input / BASE; I get C9 where I expected to get 48.
My question is, are there data limits on what can be used with the mod (%) operator? Or am I doing something more fundamentally incorrect?

I'm reading from a file the middle column of data (Volts) where my test file "AP.txt" is opened by my program. Here is a segment of the data:
time Volts dV
49552 -66.20183 -0.01556807
49553 -67.76025 -0.01556495
49554 -69.30704 -0.01533247
49555 -70.81799 -0.0148486
49556 -72.26774 -0.0141133
49557 -73.63226 -0.01315276
49558 -74.89141 -0.01201764
Since the calculation I performed gives me -71.77 Volts, I need to match this value to the time that this occurs closest to using my program, and output the time that this occurs at.
Here is my program so far:
int main()
{
std::ifstream inFile;
inFile.open("AP.txt");
ofstream results_file ("maxvaluewithinput.txt");
float TimeAtdVMax = 0;
float VoltsAtdVmax = 0;
[Code]...
If you're curious, this program isn't for homework. It's part of the independent learning on C++ I'm doing for a Master's Thesis; the program will eventually model the APD90 of a ventricular action potential.

and fill the array P[i][j] with the data.
I try to use
if (myfile.is_open()) {
//for (int i = 0; i < 1; i++)
//{
getline (myfile,DMArray[0]);
cout << DMArray[i] << endl;
//}
myfile.close();
}
But this read the data into a string. How should i do with this string. Besides I know the dimension of the data I am reading.

I am a member of a group still developing the Microprose European Air War game. We have the source code and permission to do this. As the code dates back to 1998 I use Visual Studio 2006.
I have written many programs in Visual basic, and have the following one to read the airbase value in the "targets.dat" file. The file has a four byte header containing the number of tatgets, and a 32 byte data block containing the data for each target.
Private Sub Command1_Click()
List1.Clear
Dim nt As Long
Dim a4() As Long
Open App.Path & " argets.dat" For Binary Access Read As 1
'read and display the number of targets
[Code] ....
Despite many attempts I cannot write the C equivalent of this code into the eaw.exe source. All I really need to know is how to open the 'targets.dat' file and how to get the value of a byte (or integer, or long) at a given position as in the "Get #1, k, a4(n)" line.

Trying to do a homework assignment for a class and how to read a file into an array. I've looked in our book and on several other forums and cant seem to find any examples of this. Below is the assignment I'm working on. I have a shell of the program that I can get to run, but getting a .txt file to read into an array is something I cant seem to figure out how to do.
Write a program to read N data items into two arrays, X and Y, of size 20. Store the product of the corresponding pairs of elements of X and Y in a third array Z, also of size 20. Print a three column table that displays the arrays X, Y, and Z. Then compute and print the square root of the sum of the items in array Z. Compute and print the average of the values in array Z and print all values above the average of array Z. Determine the smallest value in each array using only one function.
Use the two data files named DATAX.TXT and DATAY.TXT.
You must use functions for the reading of the data, computing the average, printing the three column table and printing the values above average.

I am currently working on a problem where I read a file into a 2D array, and display data. If you saw my code earlier, this is the same problem, but I am now further along.
The file (90 characters) looks like this:
S
R
R
S
R
R
R
R
S
S
....
The "R" resembles rainy days, the "S" resembles sunny days, and the "C" resembles cloudy days. There are 90 characters in the file. The first 30 are for the month of June, the next 30 are for the month of July, and the last 30 are for the month of August. The 31st day of the months are NOT included.
I read the data into a 3 x 30 array, where the row indicates the month (0 = June, 1 = July, 2 = August) and the column indicates the number of days in each month.
Now I need to create a function that creates a report and displays, for each month AND for the whole 3 month period:
1) The number of rainy days
2) The number of cloudy days
3) The number of sunny days
4) Which of the 3 months had the largest number of rainy days
Here is my code so far:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
const int MONTHS = 3;//Number of months
[Code] .....
There are no compiling errors, but I am not getting the data I want. My rCount and cCount variables end up being 0, and my sCount variable is 90.
