Funny, I don't want to know that you've committed to jobs you have no idea how to do. And yet, here you are....

Yes, I do. And, if you were to show any signs of doing some research and writing some code, when you asked specific questions, I'd be the first to help you.

devinaren, you made a statement as opposed to a queston. What is your question?

Your code is broken. If I could see it, I might be able to tell you where.

private void ComboBox_KeyDown(object sender, KeyEventArgs e)
{
this.ComboBox.DroppedDown = true;
if (e.KeyCode == Keys.Up && this.ComboBox.SelectedIndex != 0)
{
this.ComboBox.SelectedIndex -= 1;
return;
}
if (e.KeyCode == Keys.Down && this.ComboBox.SelectedIndex != this.ComboBox.Items.Count - 1)
{
this.ComboBox.SelectedIndex += 1;
return;
}
this.ComboBox.SelectedItem = this.ComboBox.Text + "%";
}
Hello folks. I have this event set up to search/skip to the contents of a ComboBox by the text entered, however I want to make sure I can still use the up and down keys functionality... My problem is when I run this code in my project and press the up or down keys in the ComboBox my selection moves up or down two spaces rather than one. What am I missing?
Thanks in advance!
EDIT: Sorry, the code actually was slightly wrong due to my experimenting before posting. It's fixed how I meant it to be and the problem persists. The old code was as follows and has the same outcome:
private void ComboBox_KeyDown(object sender, KeyEventArgs e)
{
this.ComboBox.DroppedDown = true;
if (e.KeyCode == Keys.Up && this.ComboBox.SelectedIndex != 0)
{
this.ComboBox.SelectedIndex = this.ComboBox.SelectedIndex - 1;
return;
}
if (e.KeyCode == Keys.Down && this.ComboBox.SelectedIndex != this.ComboBox.Items.Count - 1)
{
this.ComboBox.SelectedIndex = this.ComboBox.SelectedIndex + 1;
return;
}
this.ComboBox.SelectedItem = this.ComboBox.Text + "%";
}

Well now I feel stupid. But I guess it's the learning process.
Turns out the built-in up/down key functionality was still running, so I essentially was repeating the process with redundant code. Removing the redundant code and leaving the return function to prevent the pseudo-search function on up/down works fine.
Thanks to anyone who read and considered this.
EDIT: Hahaha! Now I think I just realized this entire process was useless since the up/down keys don't act any differently without the extra code. I need more sleep, maybe? Someone put me out of my misery!

ps. index += 1 equals index = index + 1

Yeah, I know, which is why I was so confused by it.

Hi,
I am trying to transfer a txt file by loading it and saving it with a save file dialog.
SaveFileDialog saveDialog = new SaveFileDialog();
saveDialog.AddExtension = true;
saveDialog.FileName = "Checkers Game";
saveDialog.InitialDirectory = @"C:\Documents and Settings\Bar\My Documents\";
saveDialog.OverwritePrompt = true;
saveDialog.Title = "Save game";
saveDialog.ValidateNames = true;
saveDialog.ShowDialog();
if (saveDialog.FileName != "")
{
writer.Close();
file.Close();
FileStream fs = new FileStream(@"C:\Documents and Settings\Bar\My Documents\savegame.txt", FileMode.Open);
fs = (System.IO.FileStream)saveDialog.OpenFile();
}
but when i go to the saved file i get an empty file even though the text i loaded isn't empty.
Thanks

I don't see any statement where you actually write the text to the file. It looks like the statements in the 'if' clause are in the wrong order and incomplete.
|
|
|
|

the statements in the if clause close a different stream. The one which i want to open with the new stream. Google came up with
FileStream fs = new FileStream(@"C:\Documents and Settings\Bar\My Documents\savegame.txt", FileMode.Open);
for opening txt files.

I don't know the destination file. he user desides where he wants to save it with the save dialog.

You are using the SaveFileDialog and you don't know the destination file name?

Hi,
your code seems completely wrong to me. Here are some of the problems:
- a SaveFileDialog is meant for the user to enter a new filename or choose an existing filename, or to cancel the intended operation. To do that correctly you should compare the return value of ShowDialog() against DialogResult.OK (you compare FileName with empty string, I doubt that is equivalent) and use the FileName value as the path of the output file (you don't use the value at all).
- (the part shown of) your code does not declare, create or use writer and file except for closing it, so at best something gets written somewhere else, and some (which?) file gets closed; anyway changing the state of writer and file should not be a side effect of the saveDialog.FileName != "" test, the writer and the file operation should only exist inside the code block following that test, and nowhere else.
- declaring a FileStream and opening a file inside the code block of the if statement, while not using that stream, does not make any sense. Once the if-block is done, the stream is out of scope, hence useless.
- if your code creates a FileDialog, it should also dispose of it; the using statement is the easiest way of doing it right.
I suggest you have a look at some CodeProject articles; a lot of them describe small applications that do load and save some data from and to a file, using OpenFileDialog and SaveFileDialog. Just use these as search terms in the CP search facility.
If you don't fully understand the FileDialog class, read its documentation; if you still feel uncomfortable, go buy and study an introductory book on the language of your choice. It will teach you the basics in a systematic way.

You can use this code at your own risk. I wrote it without being really awake.
using (SaveFileDialog saveDialog = new SaveFileDialog())
{
saveDialog.AddExtension = true;
saveDialog.FileName = "Checkers Game";
saveDialog.InitialDirectory = @"C:\Documents and Settings\Bar\My Documents\";
saveDialog.OverwritePrompt = true;
saveDialog.Title = "Save game";
saveDialog.ValidateNames = true;
if (saveDialog.ShowDialog() == DialogResult.OK)
{
File.Copy(@"C:\Documents and Settings\Bar\My Documents\savegame.txt", saveDialog.FileName, true);
}
}

Code looks good, however spoon feeding is bad.
