What errors do you get?

Hi,
I want to know about the stringbuilder and its use. Can it be used to read a text file line by line for further processing. Right now i m using array to read the whole contents of a text file and then processing it line by line using the array index. Is it possible by using stringbuilder. It is required to process each line in the text file seperately.
Thanx in advnace

stringbuilder can be used where string concatenation occurs.
|
|
|

The StringBuilder class has nothing to do with reading a file in. It is there strictly to allow a faster, more efficient method of concatenating strings.

Hi,
In code below I convert string to stream and now I have problem.
The value of stremReader.Readline() is never null. What I do wrong?
byte[] bytes = System.Text.Encoding.ASCII.GetBytes(stringToPrint);<br />
MemoryStream stream = new MemoryStream(bytes);<br />
<br />
StreamReader strReader = new StreamReader(stream);<br />
while (currentLine < linesPerPage)<br />
{<br />
lineText = strReader.ReadLine();<br />
if (lineText == null)
break;<br />
<br />
.... more code<br />
thanks

I would suggest using the StreamReader[^] class:
StringReader sr = new StringReader(stringToPrint);
....
|
|
|
|

I think you mean in stringToPrint is path to file, but it isn't. In stringToPrint is text converted from StringBuilder variable and contains more lines.
I just solve problem with the suggest from second reply.
Thanks for your effort.

I was just providing a suggestion as to prevent needless overhead for reading the string.
Grats on solving the problem.
|
|
|
|
|
try a loop like this :
Do While strReader.Peek() >= 0
Console.WriteLine(strReader.ReadLine())
Loop

Hey guys,
I'm facing a small problem. I have a desktop app made in C# and it workss perfectly fine on my screen resolution but when i deploy on my client's OS all the controls look wierd due to the higher/lower resolution. What can I do about this. I have heard of a library called Klib or something but its paid - 
Is there a free alternative. I dont want the controls on my form getting resized, just the spacing would be affected. Any way around this?
Thanks in advance!

If it's just the spacing you want affecting, check out the anchor property on your form.

hey,
I have a very simple problem, which I fear has a very complicated solution.
I have a form containing a treeview, consisting of several thousand nodes, and a textbox. I want the treeview to filter it's contents based on a filter string in the textbox. Here comes the tricky part: I want the treeview filter process to run simultaneously with the normal gui thread, such that the user can see the filtering of the treeview happen as he fills the textbox. Due to the large number of nodes in the treeview the call "treeView1.Nodes.Add(..);" which adds the new nodes to the treeview is very slow, and this will effect the responsiveness of the textbox where the user will experience delays as he fills the textbox.
Normally I would put the treeview filtering code in a separate thread, however .NET doesn't allow gui code that updates gui components to run in separate threads, so I'm kind of stuck.
Any ideas?
regards
Jimmy

You should create a delegate that is modying the form and invoke it in the treeview filtering thread like this m_form.invoke(delegate)
|
|
|
|
|
thank you for the fast response!
Calling Invoke doesn't solve the problem I think, when I call Invoke the process of updating the treeview is transfered to the main gui thread, and thus the delay still happens.

You need to use Control.Invoke or Control.BeginInvoke to update the UI
from a non-UI thread

Hi,
does anyone know an easy way to convert e.Graphics to an image in the paint event of a form or panel?
thx
Kurt

okay,
doesn't seem to be that hard.
A Control has a .DrawTobitmap() method.

what kind of reg exp to be specified to allow values upto 2 decimal places?(say .25 or 22.22)
vijeta
|
|
|
|
|
I assume that you also want to allow numbers without decimals?
This allows 1 or more digits, or zero or more digits followed by a period and one or two digits:
"(\d+)|(\d*\.\d{1,2})"
---
b { font-weight: normal; }
|

|

I have a Qty field in the grid. To validate this field i have used the code given at the end.
I tried various regular expressions representing decimal value, but none is working.
For all the cases, for '.' e.handled is set true. So, i am not able to get '.' as input. Can anyone help me:
private void tb_KeyPress(object sender, KeyPressEventArgs e)
{
string regexstring = @"(\d+)|(\d*\.\d{1,2})";
Regex reg = new Regex(regexstring);
if (reg.IsMatch(Convert.ToString(e.KeyChar)))
{
e.Handled = false;
}
else
{
e.Handled = true;
}
}
