Thread: Hello!! need help with a problem plz!!

I hope that someone can help me with this.

Lets say that I want to let the user of a program edit the text in a file..

Then of course he must be able to print text, and remove text.

I dont want to work against the file directly, but against a file buffer, lets say that it would be called textBuffer[].

the start location in the edit mode, would be after the last character in the textBuffer[] array..

if the user presses backspace, one char at the time will be removed from the textBuffer[] array, the screen would have to be cleared, and the textBuffer[] array outputted to the screen again..

the user should also be able to print something to the textBuffer[], where ever he is lokated, exept at textBuffer[tb_size] location ofcourse..

**The filehandling part is already done, so I dont need help with that... But I would really appriciate if someone could help me with the other stuff.

Thanks in advance!!

[code]
int lengthtb = strlen(textbuffer);

switch(textbuffer)
{
case WM_RIGHT:
//blah
break;
case //blah
//blah
}

The part that is letting the user, edit the text that is stored in the textBuffer[] array, after they have done this I will save it to the file, that they shoosed to edit, and the text in that file is located in the textBuffer[] array...

aaah I really thought that I was so clear in the above description!!

Hmm what can I say...
This was not really what I was looking for... what ever it is

Are everyone beginners at this board.. Isn´t there anyone who could help me with this problem???

I have only one thing to say..
vbworld forums, here I come....

>aaah I really thought that I was so clear in the above description!!

Clear as mud. Either you want a very simple explanation -

Use a variable as the offset to the current location in the buffer. When you encounter a backspace decrement the variable. Whenever you encounter character output write it to your buffer at this location incrementing the variable. You may want to look at alternative data structures, or even some of the containers provided by the C++ standard library to make you life easier and to enable your program to handle larger documents more efficiently.

Or, you want someone to tell you how to write MS-Word, in which case your query is far too general.

Some of us are. Most know how to ask questions though.

Sorry about that, but I am fairly new to the language...
and I have no patience..

*About my description of what I wanted, as I see it, the only way that I could have made it clearer, is if I have printed the code itself... But then I havent had to ask, had I....

But maybe it´s only seems clear to me!!

It can be hard to ask questions so they are clear for everyone. Usally we all are so deep in our own thoughts about our problems so we miss to say things that are obvious for ourself but are missing pieces of information for everyone else.

As for your problem the third post "switch statment" is what you should build from. Each case can call a function that do what you want with the array. Everything else is basiacly just to read and write to specific locations to the array. Have a variable keep track of where the user is editing and keep on building on the theory you outlined in your question. I think you are closer to the solution then you think. Sometimes when I get stuck I go of and work on some other code for awhile.

an impatient programmer probably isn't going to amount to much. On a project of any size you are likely to spend more time designing the project and debugging it than you are writing the actual code. Enthusiasm is fine. Impatience will kill.

I actually thought your initial post was good. The only problem is you posted a rough outline for a project, but no question. If you want support for your project, take the next step. Learn how to read from files into buffers. Learn how to accept user input and to recognize when the user enters backspace. Learn how to insert and delete from arrays. Everything you want to do is doable.

Thanks Barjor and Elad!!

I agree that you stated a project description but no question. And, no, not everyone is a beginner on this board.
