i am trying to create an app in c# thats a gui for a dos program.

i am a noob when it comes to programming & explaining stuff so please bear with me.

basic overview of the app is you drag and drop certain files into a list box select a few options then hit a button to lauch the external app.

running from cmd prompt you would type somthing like myapp -outputfile -option -inputfiles(upto 32 max)

so myapp.exe c:\output.img bootable c:\item1.img c:\item2.img c:\item3.img c:\item4.img

i could do it by asking the user to choose how many files the get them to browse for them using file open dialogue and storing each one in a hidden text box but this is very poor coding and leaves room for lots of errors(i have working code for this).

my drag and drop code works fine i can start the app i just cant work out how to pass the list box info to my program arguments

this is my code

{

e.Effect =

}

{

listBox1.Items.Add(file);

}

{

System.Diagnostics.

runApp.EnableRaisingEvents =

runApp.StartInfo.FileName =

private void listBox1_DragEnter(object sender, DragEventArgs e)if (e.Data.GetDataPresent(DataFormats.FileDrop, false) == true)DragDropEffects.All;private void listBox1_DragDrop(object sender, DragEventArgs e)string[] files = (string[])e.Data.GetData(DataFormats.FileDrop);foreach (string file in files)private void button1_Click(object sender, EventArgs e)Process runApp = new System.Diagnostics.Process();false;"c:/myapp.exe";

// runApp.StartInfo.Arguments = String.Format("{0} (1) (2)", textBox1.text , comboBox1.text , Listbox Items Stuck Here !! );

runApp.Start();

runApp.WaitForExit();

}

the bit i need help with is the startinfo.arguments part the 3rd option listbox items there maybe 1 or upto say15

i dont know the correct terminoligy to to search for what i want to do but i want to take all the items in the list box a pass them in the 3rd argument with spaces in between(may need to be seperated by quotes aswell)

Regards

Justin
