Hi,
Please let me know how to open a file from .net application.
Thanks in advance.
|
|
|
|
|
StreamReader sr = new StreamReader(fileName);
StreamWriter sw = new StreamWriter(fileName);
|

Thanks for your quick reply.
To open in a program, we use readers and writers.
But I would like open a file as like we open a file by double-click in system folders.
I have list of file paths in listview.
when I select those, corresponding files should get open.
Please guide me to achieve this.
|
|
|
|
|
System.Diagnostics.Process.Start(filename);
|
|
|
|
|
Use <a href="http://msdn.microsoft.com/en-us/library/system.diagnostics.process.start.aspx">Process.Start</a>[<a href="http://msdn.microsoft.com/en-us/library/system.diagnostics.process.start.aspx" target="_blank" title="New Window">^</a>].
Enjoy

See Process.Start(fileName) - that'll do 'er.
You beat me too it!

Hi all,
I want to store some files in a database. So it would be nice to keep all information (fileinfos, attributs and rights)
when they will be restored.
Is there a way to get all the (file)informations on block (struct) and not to collect them by each item with
FileInfo or FileAttributes.
And the next question is how to restore these fileinfos in an similar, easy way ?
tnx
frank

Hi,
I am executing the batch file with Process.Start(); I want to show the progress bar to the user. As it take so much time, so the user should get that its working, otherwise it seems to be hanged out.
(Note: Currently I m showing status label as process is running, but its not look good.)
Please advise me for the same.

We don't respond by email here. Any replies are posted to the forum for the benifit of others.
Just add a progress bar to your form. If you want your UI to remain responsive you can hook it up to a background worker like I've done here[^].

But batch file and windows form's progess bar/ marquee are two different process. How to run both simultaneously. As when batch process gets started, it freezes other processes.

Start the batch file in the DoWork event handler

Its not as easy to implement for me. Please guide me more.
As I have tried to execute the batch file from DoWork, its not doing whatever is desired.
My batch process runs for minimum 20-30 min.
On button click, I am runnnig following code.
Please let me know how to execute the progress bar in parallel to this.
string filePath = txtPath.Text + "\\UploadTemplates.bat";
Process proc = new Process();
proc.StartInfo.FileName = filePath;
proc.StartInfo.WorkingDirectory = txtbinPath.Text;
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.RedirectStandardInput = true;
proc.StartInfo.RedirectStandardOutput = true;
proc.StartInfo.RedirectStandardError = true;
proc.StartInfo.CreateNoWindow = true;
proc.StartInfo.WindowStyle = ProcessWindowStyle.Minimized;
// Start the process
string startTime = DateTime.Now.ToString();
proc.Start();
// Attach the output for reading
StreamReader sOut = proc.StandardOutput;
// Close the process
proc.Close();
// Read the sOut to a string.
string results = sOut.ReadToEnd().Trim();
//sOut.Close();
string endTime = DateTime.Now.ToString();
sw = File.CreateText(txtbinPath.Text + "\\UploadResult.txt");
sw.WriteLine("Process started at :" + startTime);
sw.WriteLine(results);
sw.WriteLine("Process completed at :" + endTime);
sw.Close();

Personally I don't think there's an acceptable solution to doing that. Progress bars tell you how far through an operation you are. How do we know? It depends on how large your batch file is and where you are through it. How do you know that?
Although you could kludge something together personally I would bother. Just use some sort of animated gif or something to give the user the idea that something is happening and will one day complete.

Have you used progressbars before? Doing a quick count of the number of Lines in your file and then passing that to the progressbar.Maximum gives you the number of lines you are processing.
<br />
string line = sr.ReadLine();<br />
while (line != null)<br />
{<br />
line = sr.ReadLine();<br />
lineCount++;<br />
}<br />
sr.Close();<br />
lineTot = lineCount;<br />
Once you have the total number of lines you can pass that through to the ProgressBar.Maximum.
<br />
progressBar1.Minimum = 0;<br />
progressBar1.Maximum = lineTot;<br />
Your answer seem to indicate that it is impossible to do and not worth it. I have implimented this in about less than 10 lines of code.

But the OP isn't reading lines from a file -- instead, they are running an external process (a batch file), which is quite different.
|
|
|
|
|
Yeah, thanks for that invaluable info. So now you've set the minimum and maximum how are you going to update the control as a batch file in a seperate process executes exactly?

Rob Philpott.

Exactly the same what I like to say. As its a different process, when the batch file execution get starts, it freezes all other process.
I have tried BackgroundWorker, but its not working in case of a batch file. It works for other simple processes.
Some one suggested to use Thread pool for this, I am trying with it.
|
|
|
|
|
What does your batch job do? Do you have some sample code to look at? It is probably best to use Threading.

A progress bar should show progress, so the first thing to do is answer the question: how do you measure and quantify progress? what is going to provide this information?
it depends on the action(s) going on, of which you told us nothing.
|
|
|
|
|
Not a compulsion to use a progress bar, I could use Marquee instead of it. My only moto is to show something is running, to know the user that the system has not stopped working.
|
|
|
|
|
As far as I can see from the previous replies, the only valid way to use a ProgressBar would be to set its style to ProgressBarStyle.Marquee. This would indicate that something is happening, without the requirement to measure progress.

Ya,Thanks. I am satisfied with you. I dont have any problem for using marquee, but the question is how to implement this?
|
|
|
|

Add the ProgressBar to the Form, or a StatusProgressBar to the StatusBar, then in the Properties Window set the Style property to Marquee. The marquee effect should start right away, in the designer. So to turn it on and off at the right times change the Style property, in your code. To marquee to start it, and to block (and set value = maximum) to stop it.

Thanks, But I dont have any problem in using Marquee. I know how to implement marquee, also with the help of toolStripProgressBar.
But the concern is, execution of a batch file is a diferent process, which will freezes other processes, like progressbar or toolStripProgressBar. Please guide me for that, if u can.
