Re: VS2008 Startup, Environment, Options Dialog Box missing

15-Apr-09 10:51

I have a new installation of VS2008 after a PC Rebuild and "Startup" does not appear under: Tools|Options|Environment. It was there before the rebuild.

Any ideas why it is missing and how to get it to appear? In particular I want to get VS to "Load last loaded solution" at startup.

I can't afford the 's'.

A man applied for a job to paint someone's porch for $100. The owner pointed him to several cans of white paint stacked on a weathered wood deck and told him to get started while he went in to eat lunch.

When the owner finished he went out to find the man snoozing on a rocking chair. Angrily he demanded to know why the man wasn't painting.

"I finished about twenty minutes ago. By the way, that's not a Porch, it's a BMW."

Hi! I have to read a file and do some operations to it. The contents of the file are words - it is like a dictionary (over 10 000 words, later over 80 000). Each word must be read and compared to others. Which is the best way of accessing the data (and the fastest):
1) Read the whole file and add the lines to an ArrayList, after that the stream is disposed. Then do whatever I want to the lines.
OR
2) Open the stream and read each line and do whatever I want to it. During all the time the stream is opened!

Also I want to report progress.
1) With the the ArrayList:

int progress = 0;<br />
for (int i = 0; i < rawLines.Count; i++)<br />
{<br />
   line = rawLines[i] as string;<br />
   if ((i / rawLines.Count) * 100 > progress)<br />
   {<br />
      progress = (i / rawLines.Count) * 100; //the new progress value<br />
      Console.Title = progress.ToString() + "%";<br />
   }<br />
   //<br />
   //some stuff to the line<br />
   //<br />
}

2) With the stream:

int progress = 0;<br />
int rawProgress;<br />
while ((line = reader.ReadLine()) != null)<br />
{<br />
   rawProgress = (int)((reader.BaseStream.Position / reader.BaseStream.Length) * 100);<br />
   if (rawProgress > progress)<br />
   {<br />
      progress = rawProgress; //the new progress value<br />
      Console.Title = progress.ToString() + "%";<br />
   }<br />
   //<br />
   //some stuff to the line<br />
   //<br />
}

But! Both ways don't seem to work. With the stream, the value of reader.BaseStream.Position is always 1024. In the other case the value of i increases but the percentage in the console's title does not change?!

Still learning...

I had a variant of the program as windows form application done with threads. But the same problem, also there was a cross thread problem. This variant is a console project. I don't see why there should be another thread.

Hi,

as there is no need to read the entire file at once, don't do it. It increases your memory footprint and probably decreases performance. Use the stream instead.

((reader.BaseStream.Position / reader.BaseStream.Length) * 100) is wrong: since the division has two integer operands, with numerator <= denominator, it will equal zero until the end, where it becomes one. The right way to do this is first convert at least one number to float or double, then multiply by 100, then divide, then convert back to int.

if this is a console app, there is no need for extra threads, the console would be just waiting anyway.

That worked excellent. Thank you! But what will happen if the console is closed during the read?

if you force a thread to abort and it happens to be the last foreground thread in a process, the process stops, no matter what.

In the simplest case, having a console app without extra threads, closing the window stops all of it.

If you don't like it that way, I would suggest creating a Windows app instead, and using its FormClosing event, cancel the close if you don't want it to happen.

List view question

Hi guys,

I have a list view that i want to to clear so that i can import data from a serialized file in it.
i use the listview1.Clear() command that clears also the column headers, and the de-serialization doesn't work without the column headers.

I have tried before the Clear() method this code :

<br />
                System.Windows.Forms.ListView.ColumnHeaderCollection coloane = listView1.Columns;<br />
                foreach (ColumnHeader header in coloane)<br />
                {<br />
                   listView1.Columns.Add(header.Text);<br />
                   <br />
                }<br />
                listView1.Clear();

and still it doesn't work.

Any suggestions on how to clear a ListView without the colum headers ?

Regards,
Alex

try ListView.Items.Clear() to clear the content, not the view itself.
