Henry,

This is great! Very well organized and I like the idea of having the ability to contain the integrity of the original data set. I also like the idea of outputting to an xml file as well as comparing both the original data set to the standardized data set.

I did have to modify some of the code you sent over. I had to add <string> to List and <string, string> to the Dictionaries. Let me know if this is not correct and I will go back through and make the recommended changes.

I'm still having problems populating the dgv on form 1. Maybe it's that I have not added some functionality to it. On Form 1 I added a dgv and a button name dataGridView1 and btnGetValue. On Form 2 I added a dgv and a button named dgvDocumentation and btnOK. Am I forgetting anything? I have read through the code and it compiles but just can't pinpoint what's going on.

You’re the man Henry!!!

That sounds right.
I'll go through my designer code to see if I've forgotten to tell you something obvious.

Er..................
I did tell you that I had added two dgv columns, in the designer, didn't I?

No, you say!

Here is the designer code for the first form. Just replace the code in your form1.designer.cs file with it.

I think I'll go for a lie down in a dark room now.

Ha-ha, you have a very good sense of humor. It makes it more fun and adds to my dull and busy day. You are correct sir. You did have that. I am looking through Form 2 and I see I need to add something else to get this to work. One down and one to go. I will follow up with you tomorrow. Thanks again Henry and have a good night!

Hi Henry,

I was extremely busy yesterday but I was able to work on this demo for about an hour. As it turns out I am having difficulties getting the second form to work. I looked through the code again and saw that I was missing a combobox so I added that to the dgv; however this didn't fix the issue. Can you send the designer code for the second form when you get a chance please?

Thank you,

Brenton

Check if frame in webclient is done loading

Hi Henry,

Thank you for sending me the demo. Even though I was not able to get it to work, I was able to get my app working by dissecting the code you wrote. I'm sorry I caused you frustration and thank you again for helping me on this. I will close this out now and give you the rating you deserve.

Thanks again,

Brenton

Hello.
I have a application with a webclient. In that webclient I am loading a homepage with about 5 frames, but one of the frames are refreshing constantly each 30second.
That gives me problem when I want to use the source from another frame - because when I use IsBusy and it is refreshing the frame with constantly refreshing while I am navigating another frame, does the application think that frame is done navigating too, and then I of course get an error.
It happens very often, and stops the whole program.

So is there any way only to check one frame if it is done loading ?

Hope your guys can help me out.

hello,
i am using the WebBrowser Navigate to navigate to a webpage from my c# application.
i try to post data to a form which is in that page. (its my page , i control it)

first , what is the name of the field i need to put in the post string?
is it ID or NAME ?

second , i tried various methods but none filled the form textbox with the information i sent. what am i doing wrong?

here's the c# code

WebBrowser Web = new WebBrowser();
string postdata = "ctl00_pass=1234";
System.Text.Encoding a = System.Text.Encoding.UTF8;
byte[] SendBytes = a.GetBytes(postdata);

Web.Navigate(WebBase + WebAddress, WebTitle, SendBytes, "Content-Type: application/x-www-form-urlencoded");
.

and here's the website

&amp;lt;form name="aspnetForm" method="post" action="default.aspx?key=5555" id="aspnetForm"&amp;gt;

&amp;lt;input name="ctl00$pass" type="text" id="ctl00_pass" /&amp;gt;

&lt;/form&gt;
.

tnx

Convert EBCDIC to ASCII and vice versa

Hi,
In my C# application, I need to convert EBCDIC data to ASCII. This EBCDIC data is stored as BLOB type in Teradata. This data also has packed decimals in it.

I tried the code i found on internet, which simply converts EBCDIC to ASCII. In that there a interger array of 256 characters only. But the characters which i need to convert,
char chrItem = Convert.ToChar(strEbcidic.Substring(i, 1));
returns number much higher then 256. So i get 'index out of bound of array exception'. The EBCDIC characters include 'ÁõÁõöôùô@@@@ðóùòùùðñ@ððððð' also.

Could any one please help me out here?

Thanks,
Deepa

I think the problem may be that your input is not EBCDIC - ebcdic is an 8-bit code so only has characters 000 to 255.

Hi,
Yes, none of these characters in the file are in the 255 codes of EBCDIC.

As i had mentioned earlier, the file from the BLOB, contains packed decimal also.

Are you sure its not EBCDIC, when i do .ToCharArray() i get like:
[0]: 22909 '好'
[1]: 8224 '†'
[2]: 8256 '⁀'
[3]: 8592 '←'
[4]: 879 'ͯ'
[5]: 12629 'ㅕ'
[6]: 16527 '䂏'
[7]: 16448 '䁀'
[8]: 16448 '䁀'
[9]: 16448 '䁀'
[10]: 16448 '䁀'
[11]: 16448 '䁀'
[12]: 16448 '䁀'
[13]: 65533 '�'
[14]: 49605 '쇅'
[15]: 16601 '䃙'
[16]: 16448 '䁀'
[17]: 16448 '䁀'
[18]: 16448 '䁀'
[19]: 16448 '䁀'
[20]: 16448 '䁀'
[21]: 16448 '䁀'
[22]: 16448 '䁀'
[23]: 62448 ''
[24]: 63216 ''
[25]: 63220 ''
[26]: 63473 ''
[27]: 63216 ''
[28]: 62451 ''
[29]: 61689 ''
[30]: 54769 '헱'
[31]: 16448 '䁀'
[32]: 16448 '䁀'
[33]: 16448 '䁀'
[34]: 16448 '䁀'

So their character codes are greater then 255.

How to resolve this?

The problem is that chars in .NET are Unicode, which is generally two bytes. Using a byte array instead of a char array might solve your problem.

I highly recommend using Jon Skeet's EBCDIC encoding library[^]

We have been using this for years. You basically just set up Encoding objects and pass them into Stream objects.

Granted, this is VB.NET code, but it should still make sense:

Dim inputEncoding As Encoding = EbcdicEncoding.GetEncoding("EBCDIC-US")
Dim outputEncoding = Encoding.ASCII
Dim inputReader As StreamReader
Dim outputWriter As StreamWriter
inputReader = New StreamReader(inputFile, inputEncoding)
outputWriter = New StreamWriter(outputFile, False, outputEncoding)

I don't claim to be a know it all, for I know that I am not...

I usually have an answer though.

If you need the user to be able to select a date and time then set the Format to Custom and the CustomFormat to yyyy/MM/dd HH:mm:ss

Hi guys. I have managed to resolve a proble I had yesterday with taking a value from one file and searching for it in another file. Now, my file1 containing the values I am searching for has approximately 2000 records in it. I pick up the first id in file1 and search for it in file2 which has approx 80000 records in it. Once the value has been found I replace it with another value from file1. The below code seems to taking forever to run. Is there anyway I can make this run much faster? Sniff | :^)

fileNot = textBox1.Text;
fileHid = textBox2.Text;
string[] lines = File.ReadAllLines(fileHid);
StreamWriter sw = new StreamWriter(outFile);
foreach (string line in lines)
{
    string oldhid = line.Substring(0, 11);
    string newhid = line.Substring(14, 11);
    StreamReader sr = new StreamReader(fileNot);
    string holdLine;
    while (!sr.EndOfStream)
    {
        holdLine = sr.ReadLine();
        string matchId = holdLine.Substring(0, 11);
        string noting = holdLine.Substring(11, 650).Trim();
        string dnot = holdLine.Substring(11, 2);
        if (oldhid == matchId && dnot != "D1")
        {
            sw.WriteLine(newhid + noting);
            break;
        }
    }
    sr.Close();
}
sw.Close();
swr.Close();

Any advice woudl be greatly appreciated.

Have you try'd doing everything in memory?

Read file 1 in memory (like your doing)
Read file 2 in memory

Do your operations in memory (so the replacing of the id's)

Write to your outfile

As it is now you are creating (opening and closing) 2000 streamreaders, this is bound to be a performance bottleneck.

Rather than going through the file line by line could you not just search for the index of the word and check if it's right or not (Seeing as you know exactly where everything should be if your using substrings).

StreamReader sr = new StreamReader(fileNot);
string entireFileString = sr.ReadToEnd();
sr.Close();
sr.Dispose();

int location;
while((location = entireFileString.IndexOf(oldhid)) >= 0)
{
    //Found
}

entireFileString = string.Empty;

Don't forget to Dispose() to clear up memory.

My failometer is detecting vast quantities of FAIL!

Hi,

IMO performance can be improved dramatically, however the right tactics depend on some extra info:
- Could you show say 10 lines of each of those files?
= is the order of the output lines relevant?
