Re: Reading txt file to textbox - C# Discussion Boards

Lots of different ways, but you could expose a property on one of the forms like:

public string TheValue
{
get { return theTextBox.Text; }
set { theTextBox.Text = value; }
}

Your other form can set TheValue using code like chee:

form2.TheValue = "stuff";

form2 would be an instance of your "other form" which has already been created, of course.

50 cups of coffee and you know it's on!

You can also pass it to a session variable and u can retrive the values in the form u needed.

You're very confused. Forms apps do not have session variables.

Hi
very very easy

there is 2 ways pass the value one form to a nother forms.
1.Properties
2.Constructor params

In my point of 2ndis good because of when make cons we , just create overload cons and pass the varible to that.

variable is textbox value

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<br />
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<br />
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<br />
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<br />
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<br />
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<br />
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

the split method on the string class would usually do it, but because you have spaces in words, you need to either use split them rejoin based on quotes, or write your own parser.

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:

<br />
1<br />
0	33	10	85	162	95	168	-1	5	//Bull Fighter<br />
1	29	30	40	113	45	116	-1	3	//Hound<br />
2	41	5	126	160	125	161	-1	2	//Budge Dragon<br />
3	38	5	106	161	111	160	-1	2	//Spider<br />
4	38	5	106	161	111	160	-1	2	//Elite Bull Fighter<br />
6	38	5	106	161	111	160	-1	2	//Lich<br />
7	38	5	106	161	111	160	-1	2	//Giant<br />
14	38	5	106	161	111	160	-1	2	//Skeleton Warrior<br />
end<br />
0<br />
275	33	10	85	162	95	168	-1	5	//Test 1 Section 2<br />
275	29	30	40	113	45	116	-1	3	//Test 2 Section 2<br />
275	41	5	126	160	125	161	-1	2	//Test 3 Section 2<br />
275	38	5	106	161	111	160	-1	2	//Test 4 Section 2<br />
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")<br />
{<br />
    curRec += 2;<br />
    displayLine(curRec);<br />
}<br />
else<br />
{

Here is all my code:

       // Displays the line in the arraylist<br />
        public void displayLine(int linenumber)<br />
        {<br />
            // If the line number is in the range of total values<br />
            if ((linenumber >= 0) && (linenumber < lines.Count))<br />
            {<br />
<br />
                // Get the string out of the arraylist<br />
                String line = (String)lines[linenumber];<br />
<br />
                // Split it into various pieces on the space<br />
                String[] pieces = line.Split('\t');<br />
<br />
                if (pieces[0] == "end")<br />
                {<br />
                    curRec += 2;<br />
                    displayLine(curRec);<br />
                }<br />
                else<br />
                {<br />
                    txtID.Text = pieces[0];<br />
                    txtMap.Text = pieces[1];<br />
                    txtMoving.Text = pieces[2];<br />
                    txtXStart.Text = pieces[3];<br />
                    txtYStart.Text = pieces[4];<br />
                    txtXEnd.Text = pieces[5];<br />
                    txtYEnd.Text = pieces[6];<br />
                    txtDirection.Text = pieces[7];<br />
                    txtCount.Text = pieces[8];<br />
                    txtComment.Text = pieces[9];<br />
                    mobImage.ImageLocation = "D:/images/" + pieces[0] + ".jpg";<br />
                }<br />
            }<br />
<br />
        }<br />
<br />
        // Arraylist to hold all lines of the file.<br />
        ArrayList lines = new ArrayList(100);<br />
<br />
        // Pointer variable to point to active record<br />
        int curRec = 0;<br />
<br />
        // Loading data and reading txt file<br />
        public void Form1_Load(object sender, EventArgs e)<br />
        {<br />
            // Open the data file<br />
            StreamReader f = new StreamReader(new FileStream(@"D:\monstersetbase.txt", FileMode.Open));<br />
<br />
            String curLine;<br />
<br />
            // Read in the data line by line and add it to our ArrayList<br />
            while ((curLine = f.ReadLine()) != null)<br />
            {<br />
                lines.Add(curLine);<br />
            }<br />
<br />
            // Close<br />
            f.Close();<br />
<br />
            // Add one so it will not crash<br />
            curRec += 1;<br />
<br />
            // Display first line<br />
            displayLine(curRec);<br />
        }<br />
<br />
        private void nxtButton_Click_1(object sender, EventArgs e)<br />
        {<br />
            if (curRec < lines.Count - 1)<br />
            {<br />
                curRec += 1;<br />
                displayLine(curRec);<br />
                prvButton.Enabled = true;<br />
            }<br />
        }<br />
<br />
        private void prvButton_Click_1(object sender, EventArgs e)<br />
        {<br />
            if (curRec == 2)<br />
            {<br />
                prvButton.Enabled = false;<br />
            }<br />
            if (curRec > 0)<br />
            {<br />
                curRec -= 1;<br />
                displayLine(curRec);<br />
            }<br />
        }

It all works now :P

Good Day,

I have a question about C# Express regarding it's legality for commercial use.

My family is running a small business and is need of a Sales and Inventory system which I can provide. I'm planning to use both C# express and MS SQL Express for developing the said system.

Is it legal to use it as such? Or it is limited for "educational" purposes only.

Thanks!

A) I think it's OK

B) Even if you weren't allowed to use C# Express to produce commercial apps you could still compile with the command-line C# compiler.

C) I installed SQL Server Express on the HR Director's computer and Microsoft hasn't come around and kicked in the door (yet).

Bill won't come kicking your door. I found this on their FAQ Site.

4. Can I use Express Editions for commercial use?<br />
Yes, there are no licensing restrictions for applications built using the Express Editions.

Check it out here http://msdn2.microsoft.com/en-us/express/aa718399.aspx[^]

Both are fine. They were released to compete with other totally free products and to provide a path to the full versions where needed. But, there is no limit on their use.

As the others have said, you can use both for commercial use. Have done so for a few clients and all has been good.

I have an application written in C# , and I want the users to run it from the server ( windows 2003 ) without having that application installed on each and every machine using it , Just from the server . So the user has to log to the server only to be able to run it this application .

is that possible , any Ideas how to do it ?

Regards
Dean

A server will just do this, you can either run it on the server ( using remote desktop ), or have a shortcut to the exe on the server and run it locally.

Yes I know that you have to put it on the desktop as a shortcut from the server and run it locally on each user machine , but the application does not run that way , an exception is thrown , also the more users run the application at the same time the slower it gets . Oracle has a concept of "Application server " like a web server but used for forms based application .

I have created a similar application. I used the publish feature in VS2005 (not sure if exists in 2003)

Look at the publish tab of the project properties. There should be a publish wizard that will allow you to publish the application directly to the server location.

This helps get around a lot of the permission level problems. There is also an option to have a running application to check the server for updates. This can create problems if it is linked to your PC and not the server location. I disabled this for my application.

This creates a deployment manifest method for launching an application. The end user just has to copy the shortcut created by the publish wizard to their desktop and it will launch a local version of the app from the server.

Hope this helps.

That's a different thing. The Publish feature creates a ClickOnce installer for your application. No matter whether you have an icon on your Start menu or not, the application is installed on the local machine, and everytime you run it (by going to the .application URL or clicking the icon) it checks for updates in the server. But the app is actually installed in the client PC.

And no, it's a .NET 2.0 feature so it doesn't exist in VS.NET 2003.

Thanks for the clarification on this Luis,

For my deployment I selected "The application is available online only". The app does run on the local PC but doesn't get installed there.

If you remove the app on the server then it will not run on the local PC.

Actually the app *is* installed on the local PC, but no icon is created on the start menu. It needs to be downloaded so it can be run.

Check in C:\Documents and Settings\youruser\Local Settings\Application Data\Microsoft\Apps\2.0 (the path is something like that in XP -- I have Vista and I couldn't find the path here).

I have not verified it, but I believe that if you can somehow get the .application file on your publish server, it will run your application even if you don't have a connection to the server. That's actually the shortcut gets in the Start menu when the app is installed for offline use: an .application file.

But theory aside, I think that's a great solution for what you need, since I don't think users will go hunting for you app's EXE to run it.

If you remove the app on the server then it will not run on the local PC.

If you make a change and re-publish then the remote users just close the app and re-open and it will launch the latest version.

As Christian suggested, installing it on a server and using Remote Desktop to login and run it is an option. If you want more than two users, you'll need to set up Terminal Services on your server (and have some good hardware resources -- a lot of RAM).

Running it of the network with a shortcut could also work, but usually it will run with limited security permissions (from the internet zone o intranet zone and not full trust). You're getting an exception because the app is trying to do something that is not allowed.

Hi,

There is a form thas is mdi container. That form also contains one button. When a MdiChild is displayd, I can see gray MdiClient area, button and Mdi Child form too. But the button is above the Mdi Child form when they intersect. I'd like to switch the order and when the Mdi Child form comes above the button, the button will be behind the child form instead of in front of like default.

any ideas?

thanx

zilo

You'll have to do it manually. If one of the MDI children is "above" the button, hide the button.

You could also try adding the button to the MdiClient window and not to your MDI container (your main form). It's a little tricky, but you can get a reference to the MdiClient window (the grey area that hold the MDI children).

These two articles talk about MdiClient and how to get a reference to it:
