I'm writing a program that can read out an C-file.
This is done line by line,
firt I open the file, then I read in every line of the file.
All these lines are putted in an Array,
now I have to search this array for functions, like "main", "void" etc.

So my question is,
How kan I search an array?

greetings,

Timo

That depends a lot of how you defined your array. A snippet of code would be usefull.
To search for a string into a larger string, you can use the strstr function[^]

Here's a couple of lines out of the code:

while ( fgets ( line, sizeof line, file ) != NULL )<br />
  {<br />
    rn++;                              //row counter<br />
    itoa(rn,regelnummer,10);           //int to char               <br />
    strcpy(alles[i], line);            //copy line in array<br />
    i++;                               //array counter, next line         <br />
    strcpy(alles[i], regelnummer);     //copy row number in array<br />
    i++;                               //array next line<br />
    }<br />
    fclose (file);    <br />
  }

........................................................
first the line out of a file is putted in the array,
after this the line number..
then the next line.. next line number etc..

So now all you have to do is go back through the alles array and look at all of the "even" lines. Use the strstr() function as has been mentioned.

What kind of array is that? Is it one dimensional like char sFile[SIZE] or two dimensional like char sLine[MAXLINES][MAXCHARS] ?

How are you executing it ? And what is the exact error message ?

What kind of project is it ? A dll ? Or a plain executable ? Again, what is the exact message (with the correct path) ?

Use "Rebuild All..." in the menu and confirm if asked. Then use another time the "run" button.

By the way, if it displays two '\' then it means that you did something wrong in the configuration. For the path in the configuration, you should only supply one '\' (you will never have escape sequences in a path).
That is probably your problem.

Registry confirmation

Hi,

one third party DLL that I'm using to configurate and test the connection to a plc is writing some datas into the registry in HKEY_LOCAL_MACHINE\SOFTWARE\FOLDER_1\Folder2\Device0

I want to code the deletion of FOLDER_1, Folder2, Device0 and all the values that are at the end of the path, but only when they exists. I have though using this code (Windows XP, VC++ 6.0), but before calling any code about the registry I want to be sure that it is not dangerous for the registry itselfs (it's my first try).

BOOL bDeleted = FALSE;
CRegKey rkMyRegKey;

if (rkMyRegKey.Open (HKEY_LOCAL_MACHINE, "SOFTWARE\\FOLDER_1") == ERROR_SUCCESS)
{   if (rkMyRegKey.RecurseDeleteKey ("SOFTWARE\\FOLDER_1") == ERROR_SUCCESS)
    {   rkMyRegKey.Close ();
        return MY_MSG_OK;
    }
    //To be sure it is closed although not deleted
    rkMyRegKey.Close ();
}

return MY_MSG_ERROR;

would it work?

If you are that unsure, why not create a few dummy keys and values, and work on deleting those instead?

To delete those keys is not a problem (im deleting them manually to check another things, like configuration through a *.ini), the dll will always create them, every time I run it.

My problem is that I prefer not to play with the registry just making "dummy" tries and errors, and less in a computer that is not mine.

what I am unsure about is if my code is dangerous for the registry or not.

Because of that I have asked if the code would make a safelly deletion.

No errors by compiling but either no results, it opens but doesn't deletes. Any tip?

Have you stepped through the code to see which method is failing? Why have you not tried:

if (rkMyRegKey.Open(HKEY_LOCAL_MACHINE, "SOFTWARE") == ERROR_SUCCESS)
{
    if (rkMyRegKey.RecurseDeleteKey("FOLDER_1") == ERROR_SUCCESS)
        ...
}

Because I was searching info before doing more tests. I was now reading:

A set of template classes for working with the registry
By Daniel Andersson

and

Another registry class
By SteveKing

But I will try it.

Seeing what you have writen I guess that I was uncorrectly using the functions. I thought I had to give the path till the last point you don't want to be deleted. And it just is to open to that point and use the delete with the first folder that has to be erased.

I'm checking it in a minute

Now works

Nelek1-Oct-07 4:43

Nelek

1-Oct-07 4:43

Yes, It was because of what I said in the previous message.

I was trying to open the FOLDER_1 to ensure the existance before deleting but if it doesn't exist, the RecurseDeleteKey will make nothing and return a 2 (LONG ERROR_FILE_NOT_FOUND), before I was having 5 (ERROR_ACCESS_DENIED) because I was using a wrong relative path.

why not simply renaming the output file abc.exe into xyz.exe ?
