Where exactly did you change it, and have you rebuilt the project?

Hi,

I have a project generated by Visual Studio 2010 with a tree view .

They are two tabbed pane.

I want to change the tabbed pane text and the title of the pane over.

I have tried with IDS_CLASS_VIEW, but it changes only the tooltips over the tabbed pane.

How can I change the tabbed pane and title text?

Thanks,

Claude

i want to build a program that can compile simple codes like printf,scanf,etc. can iget any suggestions ?
plus, can i add a third party compiler in a my program ?

Compile them into what? The compiler will turn source into object code, but that object still needs to be linked to the system libraries in order to run. Maybe you need to provide more information about exactly what your application is supposed to do.

well, the application should have a compiler or compiling system for simple codes and i want to know if i can add a compling system to any application. If there is a way , please reply ,
Thanks for the reply anyway.

Short answer: No.

Longer answer: It is possible to compile a complete module by calling out to a compiler from an application via ShellExecute or similar. But just compiling simple statements in isolation would entail a very large amount of work.

The simplest way is feeding an actual compiler with the code. You may use system[^], or ShellExectute[^], CreateProcess[^] for running the actual compiler.
You can add a third party compiler to your application if the compiler's license allows it (I suppose you'll find a C compiler with such a liberal license).

sorry i couldnt understand what you are saying. The thing is that i am building a application that contains a compiler and i want to know how to add it. I am still a newbie so please elaborate .

The compiler will be an external process (see above message from CPallini)

for example, on windows you could do something like :

If you edit the file in your own application, then you will need to save it on disk before compiling it.

C++

// cl.exe is the windows compiler.
// yourfile.cpp is the source file you want to compile
system("cl.exe yourfile.cpp");

After that works (calling the compiler), you can try catching the compiler result (in case of errors and warnings) and display that to the user.

This will work for simple 1 file program (with a valid main), if you want to compile and link multiple files (like visual studio do), then you will have to do a lot more work (using some sort of "make file").

Good luck.

Those two things typically do not go together well, at least not without a lot of prior knowledge. How about a less ambitious project (or two) to get you acquainted with C/C++/MFC development?

<pre lang="text">
I am trying to build a two dimmensional array - accessing LCD of 10 rows and 20 columns and be able to pass the pointer(s) to a function.
The function / method is declared in class and so is the pointer:

boolean DisplayImage(int **Display);
int **Display;

</pre>

And the function:
<pre lang="c++">

boolean CImage::DisplayImage(int **Display)
{

#ifdef DEBUG
TRACE("CImage::DisplayImage ** ", 1);
#endif

int i, j, iRow, iCol;
iRow = 10;
iCol = 20;
int iCount = 0;

for ( i = 0; i < iRow; i++) {
for (j = 0; j < iCol; j++) {
lcd_i2c.clear();
lcd_i2c.print("location ");
lcd_i2c.setCursor(0, 1);
lcd_i2c.print("row i ");
lcd_i2c.print(i );
lcd_i2c.print(" col j ");
lcd_i2c.print(j );
lcd_i2c.setCursor(0, 2);
lcd_i2c.print("Display ");
**Display = iCount++; // set test value - works
lcd_i2c.print(**Display); // display is OK
// lcd_i2c.setCursor(0, 3);
// lcd_i2c.print("mask center ");
// lcd_i2c.print(**image );
**Display++;
delay(500);
}
}

return true;
}

</pre>

Here is how I initialize the array

<pre lang="c++">
CImage::CImage (void)
{
// initialize array using pointers
// int **Display;
Display = new int *[10]; // display rows
for (int i = 0; i < 20; i++)
Display[i] = new int[10]; // display columns

}
</pre>

Here are my questions:
1. I need some explanation about this syntax "Display = new int *[10]" - is the "Display " the variable name ?
2. I may have the rows / columns reversed because I really do not understand how is the array initialized.( That is my main question - I can take it from there ).
3. Unfortunatelly the example I got this from had 10 by 10 array so I am lost as far as what are the columns and what are the rows.
4. I use rows and columns because that is the underlying hardware and I understand it is irrelevant as far as multidimmensioal array goes.
5. Under present initialization I cannot get the LCD print pass first "row". The processor just stops ( Arduino Due). I would expect it to keep printing even if I runs out of valid pointer, but that is not the case. I sure would like to know why. ( It "runs" GCC compiler).
Thank you for your time and help. Appreciate it.
Cheers Vaclav

PS I do not have a real debugger and using the LCD as "trace / debug "

Yes

This is actually a matter of how the array is used (i.e. however you define it, or if you're using someone else's code, how they define it) since it's not really a matrix.

Without looking at the code, your guess is as good as mine... Smile | :)

Does it say anything when it stops? ...is it crashing?

It basically stops here
lcd_i2c.print(**Display); // display is OK

So it may be the LCD problem.

If it crashed it should restart, but there is something different is Due (SAM) code from AVR code on start up, so it my be just stuck.

I think I am assigning the values to the wrong pointer after the first array is done.
I actually should use plain array and not pointers since I need to do convolution with 3x3 matrix to detect edge.

I am not sure this is correct - the function gets a double pointer and than I assign to double pointer. But if I assign Display = iCount the compiler does not like it and I am still learning how to "translate" compiler / Arduino error messages.

<pre lang="c++">

lcd_i2c.setCursor(0, 2);
lcd_i2c.print("Display ");
**Display = iCount++; // set test value - works
lcd_i2c.print(**Display); // display is OK
// lcd_i2c.setCursor(0, 3);
// lcd_i2c.print("mask center ");
// lcd_i2c.print(**image );
**Display++;
delay(500);

I question this. Shouldn't the for() loop only run 10 times instead of 20?

SOLVED Re: Two dimmensional array using pointers on Arduino Due

You have two main problems.

Firstly you create 10 rows and then try to initialise 20 of them each with 10 columns, try:

C++

int **Display = new int *[10];    // display rows
for (i = 0; i < 10; i++)          // initialise each of 10 rows
    Display[i] = new int[20];      // with 20 columns

When adding your counter values into the array you increment your Display pointer (which indexes the rows only), which means that after 10 iterations it is pointing to an invalid address. Try using the offset values for row and column instead, as it will also make your code clearer, thus:

C++

// iterate through the 10 rows
for ( i = 0; i < iRow; i++)
{
    // for each column in the current row
    for (j = 0; j < iCol; j++)
    {
        // set the value of count
        Display[i][j] = iCount;
        ++iCount;
    }
}

Thanks, I was pretty sure I was doing it wrong using pointers while assigning the values.
I also had the pointers array redefined in constructor.
Sure would be easier with real debugger, oh well.
Now it plays nicely.
Thanks
