Reading inside the quotations in a String (Visual C++)

[bmerlover]

Hi, I need to read a script file and change the text on the buttons I set. I have the psuedocode in my head, but I'm having trouble putting that into code. I figured out how to seperate B1 from T1 and etc. from each other. From there I haven't tried yet but I'm pretty sure I can change the text on the buttons. My question is how can I read what is inside the quotations and save that into a string. Well I can save that into a string as long as I can read it. I use the StartsWith() to find out which button the quotation belongs to and since I'm reading the richTextBox line by line, I can change the text button names inside the while loop. I just need to read inside the quotations. I'm using Visual Studio .NET 2003 C++.

example script file:

#comment
B1 = "ABC"
T1 = "DEF"
etc,

I'm currently trying many different options but here is what I have so far. My code runs fine but it is incomplete.

 
            scriptString = richTextBox1->Text;
            scriptReader = new StringReader(scriptString);
 
            int nextChar = 0;
            String* line = "";
 
 
 
            //iterate over the string using the StringReader, printing each line. 
            while(nextChar >= 0)
            {    
                //reading line by line    
                line = scriptReader->ReadLine();////
                //making sure it read correctly
 
                //richTextBox1->AppendText(str->StartsWith(“B1”);
                //line->Replace(L'B',L'A');
                richTextBox1->AppendText(line);
                richTextBox1->AppendText("\n");
 
                //check if there's any more lines
                nextChar = scriptReader->Peek();
 
            }
 
 
 
 

Thanks in advance.

I may not fully understand your problem but if you want to read string inside quotation then Split it by quotation as separator.
e.g.: B1 = "ABC" .Split('"') --> an array of string that contain B1 = , ABC, . So the second string in that array is its name ABC.

Is it what you are trying to do?

cheers.

I'm assuming you're suggesting to split each line into two parts and the first part is the button that it's assigned to, and the second is the text I need to replace it with.

Thanks vanc, I'm going to try your suggestion if I run into problems hours later, I will post another question.

Here is what I got so far. It works as long as there aren't too many spaces in between T1 = (top). Although I still have the same problem, I still can't make it parse out quotations.

When I place a quotation in delimStr
(i.e. String* delimStr = S" = ( ) ' : " \0 [ ] { } - ";), (3 quotations inside, I will bold inside one) I get these two errors.

error C2015: too many characters in constant
error C2001: newline in constant

I've done a lot of reading and debugging. It seems the best approach would be something of this nature wchar_t temp = L'"'; but I need to save it as a character array and I get errors from that as well. I've tried many different approaches of character arrays and tryed saving it to String. Still can't figure the quotations out. I need help with this, I need it to parse out the quotations and read inside of it.

Current example of code works. It takes a script file and changes the buttons. As long as the script file is saved in RTF format.

T1 = (top)
T2 = (bottom)
etc.

 
        scriptString = richTextBox1->Text;
            scriptReader = new StringReader(scriptString);
 
            String* delimStr = S" = ( ) ' : \0 [ ] { } - ";
            Char delimiter[] = delimStr->ToCharArray();
            String* split[] = 0;
            int nextChar = 0;
            String* line = "";
            String* str;
            //String* str2;// = str1->Trim(delim->ToCharArray());
            //str2 = str2->ToString(str1->Trim(delim->ToCharArray()));
 
            //iterate over the string using the StringReader, printing each line. 
            while(nextChar >= 0)
            {    
                //reading line by line    
                line = scriptReader->ReadLine();
                //making sure it read correctly
                line = line->TrimStart(NULL);
                for (int x = 0; x < line->Length; x++) 
                {    //line = line->TrimEnd(NULL);
                    split = line->Split(delimiter, x);
                    richTextBox1->AppendText(S"\ncount = {0, 2} .............."); 
                    richTextBox1->AppendText(__box(x)->ToString());
                    IEnumerator* myEnum = split->GetEnumerator();
 
                    while (myEnum->MoveNext()) 
                    {    //line = line->TrimStart(NULL);
                        String* s = __try_cast<String*>(myEnum->Current);
                        richTextBox1->AppendText(S" ");
                        richTextBox1->AppendText("Last s: ");
                        richTextBox1->AppendText(s);
 
                        //if (myEnum->MoveNext()) //save the last s (which is the name)
                        if(myEnum->MoveNext() && s != NULL)
                        {
                            str = s;
                        }
                    }
                }
 
                if(line->StartsWith("T1"))
                {
                    top1->Text = str;
                    defaultText(sender, e, top1);
                }
                else if(line->StartsWith("T2"))
                {
                    top2->Text = str;
                    defaultText(sender, e, top2);
                }
 
                richTextBox1->AppendText("\nThis is the str: ");
                richTextBox1->AppendText(str);
                richTextBox1->AppendText("\n");
                //richTextBox1->AppendText(str->StartsWith(hello);
                //line->Replace(L'B',L'A');
                //richTextBox1->AppendText(str);
                richTextBox1->AppendText("\n");
 
                //check if there's any more lines
                nextChar = scriptReader->Peek();
 
            }
 
 

Thanks in advance

I just discovered something if you put the quotation inside the delimStr with a backslash in front of it, it compiles fine.

Example:

String* delimStr = S" = ( ) ' \" : \0 [ ] { } - ";

It does parse out the quotations except there has to be a space between the word and the quotations such as:

Sample Script File:

T1 = " top "
T2 = "top"

In this example T1 works, but T2 doesn't work.

Does anyone know why and how to fix the problem? In the meantime I'm going to try and figure it out.

Thanks Again in Advance.
