a text file contains text, not formatting. the only way to give it some columnar layout without using a command language, is by inserting the right number of spaces and using a non-proportional (i.e. monospaced) font, such as Courier New. I expect there isn't a non-proportional font for Chinese.
Using tabs to replace spaces could work also, there may be some issues. And it is a first step towards a command language. Real command languages would be HTML, RTF, PostScript, etc.
In summary, there is no general solution IMO.

Much as Luc said, your choices are either to use delimiters (or markup), or to go to fixed-width columns.
You can use string.PadLeft or .PadRight to achieve columns, but you'll need to know the maximum length possible in each column (or truncate longer data).
It's not good to try to store your formatting in with your data, I would recommend delimited text or finding a solution via XML and finally using something to generate your display (rather than relying intrinsically on the stored data).
Cheers.

Hi,
Now I used string.PadRight(40, ' ') for the first text and then after adding second text.
It's working fine for english.
But for Chinese still second text is not coming below the First Row's second text.

Are you adding the required line breaks? If you reveal a bit of your code it might help others solve the problem.
As previously stated, you're going to have a hard time finding a balance of content and format. Once, there was this whole thing about HTML and CSS, and then, this other time, XML and XSL/T...

Hi!
I started a development of a application (in Windows Mobile 6) and now i have a little problem:
My datasource have 11.000~12.000 registers and when I bind it to my ListBox, this action spend 6 seconds (I think its a lot) and now I want to reduce that time.
Anyone now a way to do this?
Some code to exemplify my situation:
SQLiteConnection cnn = openCon();
string SQL = "select cod, desc from produtcs";
SQLiteDataReader sDR;
List<MyObj> data = new List<MyObj>();
cnn.Open();
SQLiteCommand sCommand = new SQLiteCommand(SQL, cnn);
sDR = sCommand.ExecuteReader();
while (sDR.Read())
{
data.Add(new MyObj(sDR["cod"].ToString(), sDR["desc"].ToString()));
}
listBox1.DataSource = data;
I need populate MyObj after, cuz this I use the variable "data"
class MyObj
{
public MyObj(int p1, string p2){ ... }
private int cod;
private string desc;
private string ...
private int ...
}

First place to start would be asking in the correct forum. See Mobile[^]
Reduce the amount of data you are trying to display. Users are not going to scroll through 12,000 items, particularly on a mobile device.

My first post and my first mistake. 
I need to load all the data, because when the user types some letters in a filter, the focus moves in the list, searching for the first ocorrence (I use a binary search, but modified and it works fine!)
I can move the topic to Mobile Forum?

It's too late to move the post now.
Populate the list after you have filtered the data.

How many entries will the user see when typing? Fetch the top 20 and display that until the user hits enter - and page the rest. Google wouldn't be very efficient if it had to send you all it's search-results and let your browser filter it.
Imagine that, with IE4.

I implemented your suggestion and like the result.
I need to do some more tests and I back later with feedback.
Thx!

Bad news 
I tried use the suggested method and the result of the test in a device (HTC Touch2) is a desaster!
The device spend much time running SQLs when I use "like" (about 1~2 seconds).
If the user type 100 characters, the total time of the operations is about 100~200 seconds. (not a good result)
I did more tests in the device, and the results are worst. Look:
SQLiteConnection cnn = openCon();
string SQL = "select cod, desc from produtcs";
SQLiteDataReader sDR;
List<MyObj> data = new List<MyObj>();
cnn.Open();
SQLiteCommand sCommand = new SQLiteCommand(SQL, cnn);
sDR = sCommand.ExecuteReader();
while (sDR.Read())
{
data.Add(new MyObj(Convert.ToInt32(sDR["cod"].ToString()), sDR["desc"].ToString()));
}
listBox1.DataSource = data;
dataGrid1.DataSource = data;
Now I'll try make it without use a List<> and insert direclty in a listBox.
At the moment the best solution.
I post my feedback later.

The trick is to load the 12K items into an in-memory data structure, and filter on that, rather than using the Like operator against the database.
|
|
|
|

Peter, I already trying do this, but i need improve the load of that 12k items.
I already tried serialize and save the data in a file and load the file into the
datasource, but the result are not good too.
After loaded in memory my data, I use a filter with BinarySearch (modified) and works great.
Thx for replys guys

This is similar to an issue I faced on mobile data terminals (MDTs) a while back. Rather than storing the data in the database, we used a series of indexed files which could quickly be read and parsed at runtime. This meant that the amount of data we held in memory at any one time was minimal, and the processing was extremely rapid.

Is the Sqlite-database located on your HTC? If so, try measuring the load-speed of a textfile to determine whether it can handle your required minimumspeed.
I'd be using the GetValues method of the datareader to get an array of objects. Won't be a wowing-difference though. There should also be a SuspendLayout method on your dataGrid control.

Hi,
Use thread to load and fill the data that will make your application responsive while the data is loading. Using thread in your application is not big deal but you have to take care about thread synchronization in your code.
hope this helps.

This still doesn't help him lower the 6 seconds or so that he's loading the data.

I have problem when I am try to send byte to serial port.
for example
int x=153;
when i get the hexa decimal of 153 it's 99
but when I am try to send it , it appear as 3F but I want it to be 99 as hexa decimal

There is more text than information here. It needs dissecting.
Honeyboy_20 wrote: I have problem when I am try to send byte to serial port.
that is not a question. And neither is the rest of your message. So I will ask some questions you can think about.
Honeyboy_20 wrote: int x=153;
why would you need an int if you want to send a byte. How about declaring a byte instead?
Honeyboy_20 wrote: when i get the hexa decimal of 153 it's 99
why would you need hex at all? how is that relevant? you can send bytes through a serial port, no matter what values they contain or whatever they represent.
Honeyboy_20 wrote: but when I am try to send it , it appear as 3F
that is a bit of a surprise. there must be some magical code involved here. I have a rough idea how one could do it, but hey, I trust your code is much better than that.

I do agree with Luc Pattyn in that sending 153 or 0x99 doesn't make any difference. It's just a matter of output formatting.
Maybe there is some decimal-to-hex formatting code in your program, which I believe you don't need at all.
The reason for me to suspect that are the following equations:
153 = 0x99
99 = 0x63
63 = 0x3F So there is a connection between the numerical values you mentioned.
Ciao,

Is that a problem with signed versus unsigned bytes? 153 is bigger than the maximum value of a signed byte, while 99 is small enough to fit into a signed byte.
But there are no signed bytes in .NET... How do you convert from int to byte?

And what do you think System.SByte is for ? :p
