upload the wave file (without asp.net control) using c# . - C# Discussion Boards

I am wondering is there a way not to repaint/redrawn an item while scrolling up and down in listbox. I want to eliminate heavy repaint. I couldn't find any resource that to cache these items.

Thanks

owner draw them and just sometimes do nothing when the event is called

Can you explain me a bit more i am painting in my own paint method but there is n't any event for scollingdown i can catch. Thanks for answering

hey can anyone can please help im new to c#, im trying to add a button to my program that will make a copy/backup of a file, the location of the orignal file is static so no need for dir listboxes. the problem i have is when it come to creating the copy.

 private void button1_Click(object sender, EventArgs e)<br />
        {<br />
            folderBrowserDialog1.Description = "Select a Directory to Back up the Database";<br />
            if (folderBrowserDialog1.ShowDialog() == DialogResult.OK)<br />
{<br />
        System.IO.File.Copy("c:/test.txt", folderBrowserDialog1.SelectedPath + "UNKNOWN.txt", true);<br />
        MessageBox.Show("File saved to " + folderBrowserDialog1.SelectedPath, "Backup Made",       MessageBoxButtons.OK, MessageBoxIcon.Information);<br />
}

any help would be great Smile | :)

I'm not getting any syntax error, however the file isn't copying if SelectedPath doesn't have a slash at the end.

+ "/UNKNOWN.txt" is a quick fix but you'll be better off testing the last character of the SelectedPath and appending the slash so you don't end up with two slashes if a root folder is selected.

just seen that i missed the "/", what an idiot... cheers!

Hi,

I'm coding a Windows Service (using the Service Project in VS 2005) and in some occasions I would need to terminate in a clean way the service from inside of the code. In OnStart I create a worker thread, and I need this thread to, somehow, terminate the service. What is the best way to do it?

Thanks,

Federico

The following code is used to upload the wave(vox) file(without asp.net control) using c# .

Great, and...?

Great. Write an article. The forums are for asking questions, not for sharing your code.

only two letters away from being an asset

hello,
can someone know how to create a c# application based on a specific software architecture or diagrams.
for example if the developper try to create a class not included in the architecture diagram so he cannot.
tanks

dghdfghdfghdfghdgh

What is it you are trying to do? I can't really understand your English...

The best way to accelerate a Macintosh is at 9.8m/sec² - Marcus Dolengo

hey if the architecture contain 2 classes so the developper cannot create in his project more than these 2 classes

dghdfghdfghdfghdgh

What are you talking about, how does creating class depends on architecture?!#@$? i dont understand!! did you mean class digram?

Oh I get what he's saying now. The answer to his question is 4.

Mark.

Actually - it's 42. Now all we need to do is build a bigger and better computer that asks the right question.

Five bucks says you'll get the diagram wrong the first time anyway.

Then you'll be paying all your developers to sit around doing nothing while they wait for you to fix it.

HAHAHHAA bad reply like you but funny.
If some one is old and don't know the new and the powerfull technologie don't say(it is better).
I mean if i have an uml diagram and i wanna to create the corrsponding code so i think that it is possible to limit my classes to the uml diagram maybe by creating this diagram in .net ....
so if someone know the right answer .... if not let his tangue inside his mouth

does it a reference to learning logical data center for visual studio

So I'm trying to find a way to bind CheckBox::Enabled to an expression that looks at a unary operation of a column in two rows of a DataTable that I'm pulling using an XSD generated by VS2005. I know I can do this through a validation event, however I'd like to do it through the designer if at all possible.

Pretty much I'd like to bind checkboxobject.Enabled to:
(someDataRow["column"]==value || nextDataRow["column"]==value)

Any thoughts on how I might be able to do this?

Without knowing what the conditions are to either turn on or off the checkbox. If its where value equals true....

if(someDataRow['column'] == true || nextDataRow['column'] == true)<br />
checkbox.Enabled = true;<br />
else<br />
checkbox.Enabled = false;

or you could use...

checkbox.Enabled = someDataRow['column'] == value ? true : false;<br />
if(checkbox.Enabled == false)<br />
checkbox.Enabled = nextDataRow['column'] == value ? true : false;

There are many ways to accomplish this task, good luck.

Just because we can; does not mean we should.
