C++ :: Processing Buttons Created At Runtime

Oct 7, 2014

I am developing a small game using MFC in which the game options like new game, save, open, exit etc. can be selected from the menu as well as from the buttons inside the window. I have no problems with the menu but the buttons do not seem to work at all.

The buttons are created at runtime using CButton class. To associate the buttons with the corresponding functions, I just used the same resource ID for the buttons as the menu options, but that did not work. When I click on the buttons, nothing happens. If I assign different resource IDs to the buttons, how do I handle the message map entries? Do I have to write different message map entries for the menus and the buttons while their function is exactly the same?

C Sharp :: How To Remove Dynamically Created Buttons In Gridview

Dec 31, 2013

I'm trying to find a way to remove an item that has been dynamically added when I change my drop down list selected user. The way this works is I add an edit and delete button dynamically when I select a user. I need to have the existing one be removed when I change users. Here is the code I'm using to build the two buttons. How do I remove them? Do I wipe out the columns and then add the columns again?

try {
    dgvBG.DataSource = this.bgDataTableAdapter.GetData(cbPatientID.SelectedItem.ToString());
    try  {
        Image editBGImg = Properties.Resources.editor;
        Image delBGImg = Properties.Resources.del;
        DataGridViewImageColumn btnBGEdit = new DataGridViewImageColumn();

Visual C++ :: Using Fstream To Open A File Created Only During Runtime?

Nov 20, 2012

I'm using Visual C++ 6.0 and I'm trying to use fstream to open and read a file that is created only during runtime. This file is written by another function running on another thread, and my program will keep trying to "open" the file until it can be opened, i.e. after it's created, then read 3 numbers from it and execute the rest of its code.

The file test.txt has the content

Code:
1
3
4

My program that polls and opens the file is as follows:

Code:
ifstream fin;
std::string tfile, snum1, snum2, snum3;
long int num2, num3;
tfile.assign(argv[1]);
printf("Begin prog %s
", tfile.c_str());

[code]....

I executed the program by

Code: test_prog.exe "C: est.txt"

and waited about 3 seconds before putting the test.txt file into C:

My output was

Code:
Begin prog C: est.txt
Cannot open file C: est.txt
Cannot open file C: est.txt
Cannot open file C: est.txt
Cannot open file C: est.txt
Cannot open file C: est.txt
Cannot open file C: est.txt
fin is open
snum1 =
num2 = 0 num3 = 0
End of prog

The test.txt file disappears after I refresh the C: folder.

So the values for snum1, num2 and num3 are all wrong, as if the file was not read correctly.

If I put a while fin.good() loop after printf("fin is open "); for that entire block (until printing the values of num2 and num3), then I get

Code:
Begin prog C: est.txt
Cannot open file C: est.txt
Cannot open file C: est.txt
Cannot open file C: est.txt
Cannot open file C: est.txt
Cannot open file C: est.txt
Cannot open file C: est.txt
fin is open
End of prog

How can I correctly read a file that is only created during runtime?

C# :: How To Get AI To Look For Specific Buttons

May 5, 2014

Basically I am creating a game and I need the ai to look for specific buttons. At the moment this is the code I have, and what it does is it makes the ai look for any random button that has't already been clicked.

Code:

private Button look_for_spaces() {
Console.WriteLine("Looking for spaces");
Button b = null;
foreach (Control c in Controls) {
b = c as Button; // performs a cast

[Code] .....

Now what I'm trying to do is make the ai go through 4 searches in steps instead of looking for any button. I want it first to look for buttons 1, 2 and 3, if there's a space in any then it will be clicked but if all of them are already clicked it will look for spaces in buttons 4, 5 and 6 and so on if that makes sense. But i'm not too sure how I would do it.

C++ :: Speech Recognition And Processing?

Jun 22, 2013

I've been coding for about 10 years now and it just got to my mind that I would like to learn about how I can create speech recognition software. I am mostly interested in doing this from ground 0 not because there are no other libs I can use, but it's more of an interest to me.

grasp this new and magnificent feature that's becoming more and more used nowadays.

My preference would be coding in C++ (more because of OOP that's why not C) and I don't really like Java.

I know what I'm getting involved in but I am thrilled and willing to go all the way to achieve my goal.

C/C++ :: Calculating CPU Processing Time?

Jun 13, 2014

I have a problem with calculating the CPUtime. I am using CPLEX to solve linear programming with 3 diferent algorithms.

1-primal Simplex
2-Dual Simplex
3-Barrier Method.

When I am trying to use Barrier method, my clock does not give me a right processing time. I don't have any problem with the other two methods. The value I am getting from ticks2 is 0 when I am using Barrier solver unlike the two other methods that I am getting some small values (ticks1 is fine). Using time_t ticks1 , ticks2 and time(&ticks1) and finally difftime(ticks1,ticks2) also gives me an integer number which is not precise enough. I need a way to compute cputime with accuracy of at least 2 decimals.

clock_t ticks1,ticks2;
double solvingtime
if (solver.primopt==1){
ticks1=clock();
status=CPXprimopt(myEnv, myLP);
ticks2=clock();

C# :: Matrix Of Buttons Variables?

Jun 14, 2014

There is a genereted matrix of buttons:

private void Single_Load(object sender, EventArgs e) {
//code here
for (int i = 0; i < n; i++) {
for (int j = 0; j < n; j++) {
//a lot of working code here
b[i, j].Click += new System.EventHandler(ClickButton);
}
}
}

What can I do when one of those buttons is pressed (i have the method ClickButton) to know what i and j has he?

I want to make something like this

ClickButton() {
if (x%2==0)
v[i, j] = x; //i and j should be form the matrix of buttons
}

C :: Remove The Functions In A Program By Pre-processing

Jun 16, 2013

Is there a program that can remove the functions in a program by preprocessing

Code:

#include<stdio.h>
int is_even(int number);
int main(void)
{
if(is_even(number))
{
printf("%d is even", number);
}
}

[Code]...

To something like

Code:

#include<stdio.h>
int is_even(int number);
int main(void)
{
if( number%2 ==0 )
{
printf("%d is even", number);
}
}

I use the "-E" option when compiling with gcc on linux but its output still contains funcitons. Is there a preprocessing program that can remove functions from a program?

C :: Processing Outputs Of Multiple Inputs

Nov 26, 2013

It's not something trivial but I would like to know the best way to process multiple outputs, for example:

Input
First line of input will contain a number T = number of test cases. Following lines will contain a string each.

Output
For each string, print on a single line, "UNIQUE" - if the characters are all unique, else print "NOT UNIQUE"

Sample Input
3
DELHI
london
#include<iostream>

Sample Output
UNIQUE
NOT UNIQUE
NOT UNIQUE

So how can I accomplish outputs like that? My code so far is:

Code:
int main(int argc, char *argv[]) {
int inputs, count=0;
char str[100];
char *ptr;
scanf("%d",&inputs);

[Code] ....

But the above will obviously print the output after each input, so I want to know how can I achieve the result given in the problem. Also another thing I want to know is, I am using an array of 100 char, which it can hold a string up to 100 characters, but what do I have to do if I want to handle string with no limit? Just declaring char *str is no good, so what to do?

C/C++ :: Creating Many Push Buttons In Win32 API

Apr 13, 2014

I am pretty new to windows programming, but i get around with small applications.

Now I want to create a window with 10 push buttons, and was just wondering if there is some smart way, maybe in a loop to create multiple buttons.

Also, on a very populated window, is there a way to maybe have the WM_CREATE commands stowed away in another cpp file? Just for readabilty.

C++ :: Processing Structured Arrays - Too Many Initializer Values

Apr 22, 2013

I working on an assignment that processes an array of structs. In the main function I am attempting to declare an array of Author structures with 3 elements. It is supposed to be initialized to set all of the string fields (the names and book titles) to "NONE", and the double fields (the prices) to zero. This is supposed to be done in one statement, not using loops. Here is what I have.

struct BookInfo struct Author
{ {
string title; string authorName;
double price; BookInfo books[SIZE] //SIZE = 3
}; };

//prototype for function to print the content of array on screen
void showInfo(Author a[], int size);

[Code] .....

I was under the impression that an array can only hold the values of one data type. So doubles and strings in the same array doesn't make sense to me. However, that's the example my teacher drew up. The error keeps telling me that there are too many initializer values.
