What is in your project is irrelevant, you don't deploy the project anyhow, right ?

Comparing lines

I'm working on a program that compares lines from two .txt files line by line.
It compares the first line of the first file then first line of the second file and so on.
But when the two files have different number of lines the program will fall.
How to solve this problem.

You can simply do it by checking the line you get first from the stream before comparing it with what so ever, sorry but not sure how to do it in c#, however you have to look for the "end of file" escape character, we use EOF in c++..

while(youStreamReader.ReadLine() != EOF)
dadadadada...

Another alternative is that you can read the entire file contents once before starting the comparison process and determine the number of lines "using the end of line escape character which you have to find out Smile | :)

" and use this number in your loop to break it later.. hope this was of some help.

When two lines do not match, you need to search ahead in both files, to see if either file has a line ahead that matches ( or better matches ) the current one. A brute force approach here is going to be very expensive, I would think.

My name is Nabeel Younus. I am doing research work fingerprint. I am looking for someone which can help in this context. I am also working but finding some problems.

So if someone has worked in it plz tell me. Perhaps I will be able to get some kind of help? Now-a-days I have been stuck on finding the corepoint in fingerprint.

I will be really grateful for favor

Great, I was going to write an article dealing with fingerprint implementation, laser applications, security and alarm systems but I dont think I still have time to do this Frown | :(

at least not this month Cry | :((

.. I'm using Graule SDK, try googling for that or you can wait for my article;)

Hello everyone

I have a Windows Application which connects the user to a remote database. I created a Web Service to detect the use's IP address. Everything works fine. The strange problem appears when I try to send the detected user's IP address back to the Windows Application. For some reason when it comes to the point that I calculate the use IP Number, the XML doesn't like the number. This is the PHP code that is calculating the IP Number:

$IPnumb = ($ips[3]+$ips[2]*256+$ips[1]*256*256+$ips[0]*256*256*256);

I have played around with it and it appears that $ips[0]*256*25*256 creates a number bigger than the XML likes. Just for a test reason I changed that and managed to find out the threshold number is $ips[0]*256*25*170.

The actual number would be 192*256*256*170 = 2139095040.

The Error Message:

There is an error in XML document (1, 497).

I was wondering if anyone else has such an experince and if anyone knows what I can do to solve this problem? Maybe it is not the XML problem and it is rather a problem of my Windows Application developed in C#. On the Windows Application ends there isn't much to talk about except that the value from the Web Service is assigned to a variable (Int32).

Thank you very much and have a great day.

Problem importing csv data in dataset with existing schema

23-Mar-07 9:13

XML doesn't care what you put into it. You're crossing the threshhold of the value that can be held in a variable along the way, I'd say.

I'd pass it as a string, and pass it as an actual IP address.

Hi,

When I import csv in dataset with is own schema, it's imported under another table as new table or it's imported in the same table in new columns and in this case the first data row is taken as column name. In the solution, I don't want to put my columns name in the csv.

Thanks for your help.

Dave

This is the part of the code;
The xsd for schema is created with vs2005

sql_select = "select * from [" + filetable + "]";
obj_oledb_da = new System.Data.Odbc.OdbcDataAdapter(sql_select, conn);

//Fill dataset with the records from CSV file
obj_oledb_da.Fill(ds, "ITEMS");
conn.Close();

sorry, but this's really funny, why dont you spare your time and search the message board for "csv" and choose one of the million posts that have been posted regarding csv. I just cant believe what's this fuss lately regarding csv!! Unsure | :~

Hi everyone

Can anyone plz tell me how to display a message from the task bar in the form of a balloon. You know like when it pops up from the task bar when u are informed to get the windows updated or when u close the messenger window and it says that it’s still running. I’m working in Windows Server 2000 SP 4 right now.
I'm workin in a C# windows application
Thanks in advance.

To display an icon in the system tray use the NotifyIcon component. If you're using Fraemwork > 1.1 you can use its BalloonTipText and BalloonTipTitle properties to display a balloon tip.

well I'm using .Net 2.0 and I've already tried using NotifyIcon but it's not working. Probably I'm missing a trick here.
I've just made a new form for testing its functionality and I've coded like this

form1_Load()<br />
{<br />
NotifyIcon n = new NotifyIcon();<br />
n.BaloonTipText="This is the text";<br />
n.BaloonTipTitle="This is the title";<br />
n.ShowBaloonTip(5000);<br />
}

so now pz tell me what to do.
what I wanna do is to use this baloon tip to show an alert in my application and when the user clicks the baloon, it should open a new form.

The notify icon is not shown by default, so you have to explicitely set its Visible property to true. Furthermore, you have to specify the icon that should be shown in the tray (assign it to the Icon property). I guess the component will throw an exception or simply does not show if you try to show it without having assigned an icon first. Finally, register to the BalloonTipClicked to open the new form.

Rocky#25-Mar-07 0:50

yes it worked when I assigned an icon to it but the strange thing is that the balloonTipClicked Event isnt working. its not responding at all. while the click and mouse click events are responding. is it bcz I'm using windows 2000 Server?? well it should be but... I can't see any other reason for it.

Maybe. Never used the balloon tip of the NotifyIcon myself, so I can't tell for sure. Try to run your code on some other machine and see if it works there.

Rocky#26-Mar-07 2:59

26-Mar-07 2:59

yes thats a good idea. I just wantd to ask one more thing... can u give me a URL where I can find some useful icons? Coz I've seen ppl using v good looking icons but I still havent been able to find any of them on the internet.

In .net 2005 I have created Application

I want to create a log file, which maintains all the internal process so at the run time I want to create a file at the source

Code:

Private string LogFileName = "ADM_Log.txt";

LogFileName = Application.ExecutablePath + "\\" + LogFileName;

This return path like this

"F:\\Joe Don't Delete\\DotNet_Samples\\ADM\\ADM\\ADM\\bin\\Debug\\ADM.EXE\\ADM_Log.txt"

1. Why the path is return with \\?
2. If I use this path in

Code:
File.Create(LogFileName);

The error message is shown like this:"Could not find a part of the path 'F:\\Joe Don't Delete\\DotNet_Samples\\ADM\\ADM\\ADM\\bin\\Debug\\ADM.EXE\\ADM_Log.txt'."

If i give manually path with single \

It creates the File.

Then

I use this function to write information in the file
At first the file is created in single \ then it goes to this function
At first line of this function it throws message "the file is exclusively opened by another user"

Private void WriteLog(string sMessage)
{

StreamWriter sw1 = File.AppendText(LogFileName);
sMessage = ("::" + sMessage);
sw1.WriteLine(sMessage);
sw1.Close();
}

Please help me these all my problems

Thank u
