I am writing a program that downloads a database on remote laptops, When downloading the file I noticed that my program uses about 15 MB of memory and calls Windows Explorer and WE uses about 16 MB of memory, the database file is about 60MB. I was wondering if there is something i am missing to reduce the amount of memory I am using. the laptops that will be using this app are older laptops and I want this process not to interfere with another database app that is very memory intensive. and once the download is complete it does not release the memory to a reasonable level any ideas.
Thanks
Rob
FileStream fs = null; //' To access the local file;
WebRequest req;
//StreamReader sr;
try
{
// This sets up the Request instance
req = WebRequest.Create("http://www.domian.com/file.zip");
// Use a GET since no data is being sent to the web server
req.Method = "GET";
// This causes the round-trip
WebResponse rsp = req.GetResponse();
try
{
// Open the file to stream in the content
fs = new FileStream("file.zip", FileMode.Create);
// Copy the content from the response stream to the file.
CopyData(rsp.GetResponseStream(), fs);
}

How exactly are you copying the data from the response stream to the file stream?
Another thing to consider is that looking at memory usage in the Task Manager (which is what I assume you are doing) can often be misleading. The allocated memory listed for a .NET-based application often includes memory which has been collected (i.e. released) as far as the application goes, but which simply hasn't been given back to the system by the runtime. However, that memory can be given back if and when the runtime believes the system needs it.
If there are specific performance (memory or CPU) requirements for your application, then I would suggest using a profiler to help determine where the bottlenecks are in your application.

Hello everyone,
I have a string which I would like to remove the SPACE in the string. For example, I would like to change "I would like to remove any space." into "Iwouldliketoremoveanyspace.".
Can anyone be kind enough to tell me how I can get this done?
Thank you very much and have a great day.

Doesn't that only remove the spaces at the beginning and end of the string?

True .. sorry, you can use Christian's suggestion replacing white spaces.

No. That only removes spaces. White space includes characters like tab and line breaks.

Okay "black" spaces;P.. no seriously, you can remove tabs at least doing this:
string strTabs = "a\t\t\tb";
MessageBox.Show("Before: "+str);
MessageBox.Show("After: "+str.Replace("\t",@"<tab>"));
string strNewLines = "a\n\n\nb";
MessageBox.Show("Before: "+str);
MessageBox.Show("After: "+str.Replace("\n",@"<enter>"));

That's really awful. Why would you rewrite a method that's already in the framework ?

Hi programmer,
Im doing a project, my question is " How to allow the file to popup when the button is click." The file is in (C:\Documents and Settings\Lohsk\My Documents\Introduction.txt). Can someone help me  .The program must written in c#.

Process.Start will open your text file in the default program ( probably notepad ). You can use File.ReadAllText to read it and display it yourself.

try this:-
private void button1_Click(object sender, EventArgs e)
{
try
{
System.Diagnostics.Process process = new System.Diagnostics.Process();
process.StartInfo.FileName = @"C:\Documents and Settings\Lohsk\My Documents\Introduction.txt";
process.StartInfo.ErrorDialog = true;
process.Start();
}
catch (Exception err)
{
MessageBox.Show(err.ToString());
}
}

What do you want to do ? You want to dictate what memory a program runs in ? Process.Start will run an exe.

How to know a EXE file was written by .net language or not?
|
|
|
|

In what context ? You can run reflector on it and see if you can see the source code. You can examine the header, if you want to do it within a program.

Then you need to find out exactly how the file itself marks that it is .NET, and write code to read the head of the file and examine it for this info.
