Hello.

I am developing a program where I have some textboxes and forward and previous buttons.
I also have a txt file. I want to read from my txt file and then write to my textbox.

My txt file looks like this:

19 1 "Yeti" 30 900 0 105 110 37 0 150 37 2 17 4 6 400 2000 10 2 180 14 6 0 0 3 0 0
20 1 "Elite Yeti" 36 1200 0 120 125 50 0 180 43 3 0 1 6 400 1400 10 2 180 14 6 0 1 4 1 1
21 1 "Assassin" 26 800 0 95 100 33 0 130 33 2 0 1 7 400 2000 10 2 180 14 6 0 0 0 0 0
22 1 "Ice Monster" 22 650 0 80 85 27 0 110 27 2 7 1 5 400 2000 10 2 170 14 6 0 0 3 0 0
23 1 "Hommerd" 24 700 0 85 90 29 0 120 29 3 0 1 5 400 1600 10 2 170 14 6 0 0 3 0 0
24 1 "Worm" 20 600 0 75 80 25 0 100 25 3 0 1 4 400 1600 10 2 160 14 6 0 0 2 0 0
25 1 "Ice Queen" 52 4000 0 155 165 90 0 260 76 3 11 4 7 400 1400 50 2 180 14 3 0 4 5 4 4

I want it to read one line and then for example set Yeti and 19 into a textbox

When you push forward it reads elite yeti and 20

But I don't know how to do

I am assuming I need space as a separator and then use like var[3] where 3 is the third word.
A little like in mirc where you can write
$gettok(one two three, 32, 3) where it picks the 3 word with the separator space (32)

But when it gets to the code and not the idea im kinda stuck. Any ideas?

Im using Visual C# 2008 Express Edition

Well one way to do this is to load up all the lines into an array of some sort. I used an arraylist in the example below. Then create a display function which uses a pointer variable to point at each string, split it, then put the pieces into the textboxes. You would use the next and previous buttons to control the pointer variable and to refresh the boxes.

It is crude but effective and the only bug in it is that your create names that have a space in them are also split so the name "ice monster" would appear in the textbox as "ice

That will be your homework to work on. Once you get it, problem solved.

// Arraylist to hold all lines of the file.
        ArrayList lines = new ArrayList(100);

        // Pointer variable to point to active record
        int curRec = 0;

        private void Form1_Load(object sender, EventArgs e)
        {
            // Open the data file
            StreamReader f = new StreamReader(new FileStream("c:\\data.txt", FileMode.Open));

            String curLine;

            // Read in the data line by line and add it to our ArrayList
            while ((curLine = f.ReadLine()) != null) {
                lines.Add(curLine);
            }

            // Close
            f.Close();

            // Display first line
            displayLine(curRec);
        }

        // Displays the line in the arraylist
        private void displayLine(int linenumber)
        {
            // If the line number is in the range of total values
            if ((linenumber >= 0) && (linenumber < lines.Count)) {

                // Get the string out of the arraylist
                String line = (String)lines[linenumber];

                // Split it into various pieces on the space
                String[] pieces = line.Split();

                // Populate the text boxes with the appropriate pieces
                txtID.Text = pieces[0];
                txtName.Text = pieces[2];
            }

        }

        // Moves the pointer variable back one and displays the value
        private void btnPrevious_Click(object sender, EventArgs e)
        {
            if (curRec > 0) {
                curRec -= 1;
                displayLine(curRec);
            }
        }

        // Moves the pointer variable up one and displays the value
        private void btnNext_Click(object sender, EventArgs e)
        {
            if (curRec < lines.Count - 1) {
                curRec += 1;
                displayLine(curRec);
            }
        }

Read the in code comments to see how I am doing this. If you want to rip out the splitting of the line and do something with the line read in, feel free. It is up to you as to how you want to handle the line once you read it in.

This is only a quick example. Enjoy!

It might be a quick example, but it works like a charm

I only have one question now

I got the button back to be disabled when there are nothing to go back to with:

		   if (curRec == 1)
			{
				prev_monster_button.Enabled = false;
			}

And then in the next button code I am enabling in it again:

			if (curRec < lines.Count - 1)
			{
				curRec += 1;
				displayLine(curRec);
				prev_monster_button.Enabled = true;
			}

But how do I do it so it will disable my next button like my previous?

If there is no content for the next button it should be disabled

Im kinda confused there

[Martyr2]

Just check if curRec is equal to the arraylist count. You see how in the next button you check if curRec is less than arraylist count? Well after you hit the last record and increment curRec, it will equal arraylist count and hence make that if statement false and won't let you go to the next record right? At that time you would disable the next button.

You are my hero!

			if (curRec == lines.Count -1)
			{
				next_monster_button.Enabled = false;
			}

Success

Would be fun if the site was named something with a K in the end

I have created a way so it takes ice monster

But is it a good way and how do I combine the string that I marked with a bold with a space between so it is Monster Name and not MonsterName?

				// My string to split
				[b]string str = pieces[2] + pieces[3];[/b]

				// Split seperator
				char[] seps = {' '}; 

				// Split the string into parts. 
				string[] parts = str.Split(seps);
				for (int i = 0; i < parts.Length; i++)
					monster_name_textbox.Text = parts[i].Replace("\"", "");;

Im guessing it should be something like:
string str = pieces[2] + " " + pieces[3]; but cant seem to get it to wkr

Well if you simply deleted the space in the name, it will be read in as a whole string there. You might want to consider replacing the space with a special character like an underscore and simply read in the name and replace the underscore with the space.

It is up to you and your design as to how you want to do that.

I have been ripping my hair out because I cant find a solution.

I got it all working, but now I must format more text

I got a new text that has sections like this:

1
0	33	10	85	162	95	168	-1	5	//Bull Fighter
1	29	30	40	113	45	116	-1	3	//Hound
2	41	5	126	160	125	161	-1	2	//Budge Dragon
3	38	5	106	161	111	160	-1	2	//Spider
4	38	5	106	161	111	160	-1	2	//Elite Bull Fighter
6	38	5	106	161	111	160	-1	2	//Lich
7	38	5	106	161	111	160	-1	2	//Giant
14	38	5	106	161	111	160	-1	2	//Skeleton Warrior
end
0
275	33	10	85	162	95	168	-1	5	//Test 1 Section 2
275	29	30	40	113	45	116	-1	3	//Test 2 Section 2
275	41	5	126	160	125	161	-1	2	//Test 3 Section 2
275	38	5	106	161	111	160	-1	2	//Test 4 Section 2
end

Now I changed my script so it reads the values from this script, and I changed the forward button so it jumps into new sections

But I just cant seem to figure out how to jump back to a section

This is the code that I use to go foward into a section:

				if (pieces[0] == "end")
				{
					curRec += 2;
					displayLine(curRec);
				}
				else
				{

Here is all my code:

	   // Displays the line in the arraylist
		public void displayLine(int linenumber)
		{
			// If the line number is in the range of total values
			if ((linenumber >= 0) && (linenumber < lines.Count))
			{

				// Get the string out of the arraylist
				String line = (String)lines[linenumber];

				// Split it into various pieces on the space
				String[] pieces = line.Split('\t');

				if (pieces[0] == "end")
				{
					curRec += 2;
					displayLine(curRec);
				}
				else
				{
					txtID.Text = pieces[0];
					txtMap.Text = pieces[1];
					txtMoving.Text = pieces[2];
					txtXStart.Text = pieces[3];
					txtYStart.Text = pieces[4];
					txtXEnd.Text = pieces[5];
					txtYEnd.Text = pieces[6];
					txtDirection.Text = pieces[7];
					txtCount.Text = pieces[8];
					txtComment.Text = pieces[9];
					mobImage.ImageLocation = "D:/images/" + pieces[0] + ".jpg";
				}
			}

		}

		// Arraylist to hold all lines of the file.
		ArrayList lines = new ArrayList(100);

		// Pointer variable to point to active record
		int curRec = 0;

		// Loading data and reading txt file
		public void Form1_Load(object sender, EventArgs e)
		{
			// Open the data file
			StreamReader f = new StreamReader(new FileStream(@"D:\monstersetbase.txt", FileMode.Open));

			String curLine;

			// Read in the data line by line and add it to our ArrayList
			while ((curLine = f.ReadLine()) != null)
			{
				lines.Add(curLine);
			}

			// Close
			f.Close();

			// Add one so it will not crash
			curRec += 1;

			// Display first line
			displayLine(curRec);
		}

		private void nxtButton_Click_1(object sender, EventArgs e)
		{
			if (curRec < lines.Count - 1)
			{
				curRec += 1;
				displayLine(curRec);
				prvButton.Enabled = true;
			}
		}

		private void prvButton_Click_1(object sender, EventArgs e)
		{
			if (curRec == 2)
			{
				prvButton.Enabled = false;
			}
			if (curRec > 0)
			{
				curRec -= 1;
				displayLine(curRec);
			}
		}
