What if there's more than one file called simple.txt?
You can start by looking at the System.IO namespace.

So, basically, you want someone here to write the bulk of your application for you?? That's not going to happen. YOU have to write the code. We're just here to help with any specific problems you may encounter. Seeing as though you have no code to connect to a database, save information to it, or retrieve information from it, you really need to start by learning how to do database operations.

Hi all,
I have the following string “Shirt85” and I want to separate it in two different strings “Shirt” and “85” (85 can be a int) .. How can I do it?
e.g.
string1=Shirt
string2=85
I want that 85 no. from string.

Check your string characters one by one.
int resultstring; // For Numaric Value only
string resultstring1; // For String Value Only
for i =0 to len(string)
{
if isnumber(string.substring(i,1))== true
{
resultstring =convert.toint( string.substring(i,1));
}
else
{
resultstring1 = string.substring(i,1);
}
}
If you can think then I Can.

Thanx for reply but My code is in c#....
i modified code according to C#...but it gives error : The name 'len' does not exist in the current context......and for all string operations....What i have to do?m new wid this....is there any name space required to add into project.

String.Length or Microsoft.Visualbasic.len is gives the length of string.
You should have basic knowledge of Programming. Read books or search in Google for Basic Concept.
If you can think then I Can.

Or better:
{
string s = "String85";
string s1 = "";
string s2 = "";
int posn = s.IndexOfAny("0123456789".ToCharArray());
if (posn >= 0)
{
s1 = s.Substring(0,posn);
s2 = s.Substring(posn);
}
MessageBox.Show(string.Format("\"{0}\" \"{1}\"", s1, s2));
}
You could do the digit finding with a Regex, but this example is just to be obvious!

Hi, I want to do my progress bar in to pop up progress bar. i mean when i load something i want to pop up progress bar while progressing only. how can i do that. i wrote the coding for static progress bar. i mean drag & drop progrss bar from tool in to my form.
ProgressBar ProBar = new ProgressBar();
private void import(object sender, EventArgs e)
{
if (listView1.Items.Count == 0)
{
ImageList imageList = new ImageList();
imageList.ImageSize = new Size(100, 80);
imageList.ColorDepth = ColorDepth.Depth32Bit;
this.ProBar = new System.Windows.Forms.ProgressBar();
this.ProBar.TabIndex = 0;
this.ProBar.Maximum = dlg.FileNames.Length;
this.ProBar.Minimum = 1;
this.ProBar.Step = 1;
foreach (string path in dlg.FileNames)
{
FileInfo fileInfo = new FileInfo(path);
listView1.Items.Add(fileInfo.Name);
imageList.Images.Add(Bitmap.FromFile(path));
ProBar.PerformStep();
}

I guess I have already answered this few days back. To reiterate, you need to create a new form and place progress bar in that. Create methods in that form which updates the progress bar. You can call this method from your form whenever a progress happens.

Hi, thanks a lot for your reply,
may i know some thing...
how about if i creat a method in my exicting form and cal that method when i need progress bar.is this posible to do?? i tried this out but by this way i couldn't get progress bar like message box....

What do you mean by progress bar like message box? A modal progress bar which will not allow to click on other forms when progress is shown? If yes, here is a method
1 - Create a new form say Progress
2 - Add a progress bar say "pb" to this form.
3 - Create a delegate in this form which will call back the method to execute from the progress window. Refer the following code
public class ProgressEventArgs
{
ProgressBar pb;
Form form;
public ProgressEventArgs(ProgressBar pb, Form form)
{
this.pb = pb;
this.form = form;
}
public void PerformProgress(int value)
{
form.BeginInvoke((MethodInvoker)delegate
{
this.pb.Value = value;
});
}
public void StopProgress()
{
form.BeginInvoke((MethodInvoker)delegate
{
form.Close();
});
}
}
public delegate void WorkStartedHandler(ProgressEventArgs pe);
public partial class Progress : Form
{
WorkStartedHandler method;
public Progress()
{
InitializeComponent();
}
public void ShowProgress(int minimum, int maximum, WorkStartedHandler method)
{
pb.Minimum = minimum;
pb.Maximum = maximum;
this.method = method;
new Thread(DoWork).Start();
this.ShowDialog();
}
void DoWork()
{
method(new ProgressEventArgs(this.pb, this));
}
}The above code is simple and self explaining. You can use this like
private void import(object sender, EventArgs e)
{
if (listView1.Items.Count == 0)
{
Progress p = new Progress();
p.ShowProgress(1, dlg.FileNames.Length, DoWork);
}
}
void DoWork(ProgressEventArgs pe)
{
int i = 0;
foreach (string path in dlg.FileNames)
{
.............
.............
++i;
pe.PerformProgress(i);
}
pe.StopProgress();
}I wrote the above code in CP editor directly, so expect some compile time errors.

Hi , have a good day ...
I don't know if this is the right place for my Question ...
so please excuse me if I am worng ....
My Question is :
if I excute On SQL Query Analyzer this Syntax (
dbcc checkdb ('master') )
then the SQL Query Analyzer will print a message like this :
DBCC results for 'master'.<br />
DBCC results for 'sysobjects'.<br />
There are 1221 rows in 23 pages for object 'sysobjects'.<br />
.<br />
.<br />
How I can read Such a thing with C# Windows Application ...
I need a hint , don't bother your self for writting a code ,
But I will be happy if you did ...
Kimd regards
Thank in Advance
I know nothing , I know nothing ...

Hi,
if you launch the analyzer from within a .NET app (using Process.Start), you can catch the output and error streams, and deal with their content any way you see fit.
In general the correct way is by using three threads: one reading the output stream, one reading the error stream, and one orchestrating the launch and the termination; something the MS examples fail to illustrate.
For fast jobs without much output, you can do without it all, just ReadToEnd on both streams (which means you will get output only when all is done).

Correct me if I am wrong - Analyzer is not a console application. So how can you predict where this output message is coming and read only that portion from your application? I don't think it is possible.
Any thoughts?

Oh.
If it is a WinForm app, one can always try and get the text from the Control that holds whatever is relevant... (using some P/Invoke that is).
