The below code is working fine in VS2008 and not working in VC6.0 (taking garbage values) this code is for converting hex values to string.
sending Input string is : 727332333263 required output: rs232c
DWORD AsciiToString(LPCTSTR f_chInputChar, LPTSTR f_chOutputChar) {
long ch;
int i,j;
TCHAR tmp[2];
int len = _tcslen(f_chInputChar);

I am having problems with converting a CString to an int and than doing checks on the int to see if it is in a particualr range.Below is what I am doing.
CString numstr = "28"
int num = atoi(numstr);
BOOL valid = TRUE;
if(num < -32,768 {
valid = FALSE;
}
For some reason when running the above code the if statement is executed but it should not be becasue 28 is not less than -32,768. Why this is happening, I am not seeing the reason for this at all!! The num variable is being assigned the correct value.
ShAltGr+A represents a foreign character in a font set.
How to make a CString variable for this so it can be displayed in a text editor programmatically?
Typing the combination of course works.
I have saved the contents of an int vector to a txt file and the numerical data was converted into a c-string. Nov I need to import and read the contents back into my program but I have not been able to convert c-string numerical data back into ints.

Code:
struct print {
int x; //row
int y; //col
int fid;
CString *data;
char *format;

the char *format is not a problem, but compiler doesn't like CString *data;
tried CSting data and that also doesn't work, typecasting didn't work either?
Why would the following line of code cause an exception and how can I fix it? This is with Visual Studio 2013 and it is set to use "Multibyte Character Set". This is a very old program that I was updating.
Code: thepath = dadir + "*.csv";
Both dadir and thepath are type CString.

I have a non-MFC static library which I share between a number of different projects, some non-MFC and some MFC. Currently the static library uses a typedef of std::wstring and std::string for UNICODE and non-UNICODE builds.
After discovering it's possible to use CString in non-MFC applications, by including atlstr.h header, I decided I'd rather that than using stl strings and having to keep converting between the different types. However, I seem to be struggling with linker errors when linking the library with a MFC application.
Can I create a non-MFC static library using CString from atlstr.h and link it with a MFC application?
How do I detect garbage chars in a CString. Actually I'm reading some data from COM port. In some certain condition it will give some garbage as a version no. Now I need to show _T("N/A") in case of there is any garbage.
My solution is to check for a Valid char or integer. If found its correct else Garbage.
I am trying to display some data in text format on a dialog and I am using a CString to do it. Below is how I coded it.
Code:
CString outputStr;
CString auxStr;
// Add header
outputStr.Format("");
auxStr.Format("%-7s%-20s%-7s%-20s%s
[Code] .....
But the output rows are not aligned as shown in the attached picture. There a two problems.
1. Data rows don't align with the header row.
2. When the first element of a row changes to two digits, the other elements are shifted.
According to MSDN [URL] ...., CString::Format() works the same way as printf(). I wrote a small program using printf() to do the same thing, and the output in the console are perfectly aligned.
What have I missed when doing the display in GUI?
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.
View 11 Replies View RelatedI'm currently trying to work with more than one form, but I didn't succeed yet. What I need is quite simple: Once the program runs, a small form appears first asking "what would you like to do" with corresponding buttons for each option. Each button loads a new different form for a different task. So basically I need to open and close forms, also having two forms loaded at the same time (pop-up style) would be great for certain purposes.
I still haven't figured how to do it properly. I'm currently using VC++ 2008 and my project is a Windows Forms Application.

I have a slider control on a dialog box. I am playing a video file and slider moves according to the video elapsed. Suppose I have set the slider range to 100. Now till some point say 90, the slider moves to the point wherever I click the mouse. but at the last point in between some range say 90 - 100 (to the end of the slider), if I click the mouse button anywhere, slider jumps to the end.
I am using a TimeLine control where user can add more than 1 video (1, 2, 4, 8, 10 , 50 etc......), If I use only one video, slider moves as per the video progression.....Issue arises when I add more than 1 video and click on the start button, slider starts moving....Now when I drag the slider to any position or I click the mouse button anywhere on the slider control, slider thumb moves to that position and immediately jumps back to some other position. This is the Issue, I am facing.
share some sample code where slider is moving with the video showing the progress of the video.
I want to implement a functionality similar to VLC player. Wherever user clicks the mouse, slider moves to that point.
My code is below:
Total Interest ends up as my last Monthly Payment amount instead of adding up all Interest Paid - What am I doing wrong?
Total Paid isn't calculating correcly either - What am I doing wrong?
I suspect both are very similar problems. I've tried several different calculations, but cannot figure this out.
#include <iostream>
#include <cmath>
using namespace std;
double GetMonthlyIntrest (double OpenBalance,double rate);
bool ContinuePgm();
int main () {
double StartingBalance,rate,amount,OpenBalance,IntPmt,TotalInt=0.0,GrandTotal=0.0;

This program is suppose to store input from a user (example 14 15 27) and output it three times. Once to confirm the input using the get function to recall the data, once to look like military time (14:15:27), and once to look like slandered time (2:15:27 p.m.).
The program runs, but this is what I'm getting:
I'm thinking its because I'm using the same integers to store two sets of data. I tried to create different integers for every set of data it didn't seem to fix the problem. The fact that the program is running makes trying to figure out where the problem quite confusing to say the least.
Code:
#include <iostream>
using namespace std;
class time {

int hr, min, sec;

As a starter project I want convert a Neural net app from "AI Techniques for Game Programming (2002 Buckland)" to a Visual C++ CLI Forms application. I have created the interface and now I have to rewrite the in/output routines, amongst other things.
First question I have has to do with variable initialization used by Buckland. Code looks like this:
Excerpt from header file (CNeuralNet.h):
//-------------------------------------------------------------------
//define neuron struct
//-------------------------------------------------------------------
struct SNeuron
{
//the number of inputs into the neuron
int m_NumInputs;
//the weights for each input
vector<double>m_vecWeight;
[code]....
Question I have: what is the the function of ": m_NumInputs(NumInputs+1)" after the method declaration? Buckland does this in many places in his code. In this case it's a struct, but he does it with classes too.
I keep having problems with CMFCPropertySheets. I now have it embedded in a resizable dialog and the property sheet and page gets resized when dialog is resized all that is working fine.
Problem is OnSize is being called when the dialog is being resized NOT when it has finished resizing so the values reported in cx and cy is the old size not the size AFTER resizing. What could be causing this? Isn't OnSize call AFTER the size has been changed and OnSizing called WHILE the size is being changed?
I have a list control that needs to take up full rect in each page and when the dialog is maximized it stays at previous size even though the sheet and page have both maximized as they should.
I ran a trace on the OnSize even for both the sheet and page and OnSize is being called during the sizing and not after it has already been sized like it is supposed to.
Just using Find in my source code to look for variables or whatever, works once or twice then just stops - Doesn't find anything even if it's there. If I restart VS it works again, but not for long.

View 1 Replies View RelatedI followed a tutorial to load a bitmap from file and convert it to a array of bytes to access it directly. Now to display the bitmap on screen do I have to convert it to a HBITMAP or can I display it from the array of bytes?

here is the code to load the bitmap

Write a C++ program that adds three binary numbers of 8-bit each. Every number is stored into an array of 8 elements.
Example:
Array A
0 1 2 3 4 5 6 7
0 1 1 0 1 1 1 0
+
Array B
0 1 2 3 4 5 6 7
0 1 1 0 1 1 1 0
+
Array C
0 1 2 3 4 5 6 7
0 1 1 0 1 1 1 0
Store the result into an array D of 8 elements. Your program should show the decimal numbers for every binary number. Print screen of 6 answers. This means you should try your program six times with different numbers in every run and show the printed screen result.
