VB adobc matching problem

cloudet — Tue, 08 Apr 2008 00:20:38 +0800

Dear all,
I wrote these codes to compare datafields in my access mdb with user input value, with some thresholds.

CODE

Private Sub cmd_reg_Click()
Do Until Data1.Recordset.EOF
Data1.Recordset.MoveFirst
If (Data1.Recordset.Fields("ratio_1") - ratio1) ^ 2 < (0.03) ^ 2 And (Data1.Recordset.Fields("ratio_2") - ratio2) ^ 2 < (0.05) ^ 2 And (Data1.Recordset.Fields("Ratio_4") - ratio4) ^ 2 < (0.05) ^ 2 And (Data1.Recordset.Fields("Ratio_5") - ratio5) ^ 2 < (0.1) ^ 2 Then
txt_name.Text = Data1.Recordset.Fields("name")
txt_matric.Text = Data1.Recordset.Fields("matric_no")
Else
Data1.Recordset.MoveNext
End If

When i ran my project, it hangs there, and whole VB program was not responding. I think there's something wrong with the loops.
Can someone see and point out my mistakes? Till now i can't figure out why, and my head get dizzy liao.

Note tat ratio_1,...ratio_5 are data fields in my mdb; while ratio1,...ratio5 are input from user.

CODE

(Data1.Recordset.Fields("ratio_1") - ratio1) ^ 2 < (0.03) ^ 2

Codes above are my thresholding process onto user input.

Thanks in advance.

delete string in JtextArea

cloudet — Tue, 01 Apr 2008 10:45:38 +0800

Dear all,
I'm doing a simulation to demonstrate Linda, and now facing some problems.
This is the printscreen of my simulation
[attachmentid=431312]

when "connect to server" button is pressed, both agent 1 and agent 2 can input operations into uts (textarea).
out means output a value into uts;
rd means search a value in uts;
and in means search a value in uts, and when it's found, the value will be deleted from uts.
note tat for simplicity of simulation, value here means string.

Now the problem for me is how to delete the string from uts txtarea when a string is found.
[attachmentid=431313]
I can only output a msgbox when a string is found, and can't delete it.

Here's part of my codes:

» Click to show Spoiler - click again to hide... «

Anyone can help me?
Thanks in advance.

Storing pixel locations

cloudet — Mon, 10 Mar 2008 16:50:46 +0800

Dear all,
Given a picture, i need to store the pixel locations when user clicks.
I can now only store one pixel value only. I need to get 5 pair (x and y) of pixel locations.
The codes are as following:

» Click to show Spoiler - click again to hide... «

As u can see above, i try to out put x1, y1,...,x4, and y4 in richtextbox1 and richtexbox2. But every time i get is same value.
[attachmentid=414410]
And richtextbox3 just gives me "0".
Can anyone point out wat's wrong with the code above?

Thanks in advance.

Reading multiple text files

cloudet — Wed, 05 Mar 2008 15:27:32 +0800

Dear all guru,
I'm newbie in Visual Basic 6.0

Supposed that i have files named face1.txt, face2.txt, face3.txt,..., face7.txt.
Each of the txt file contents are the same:
line 1 is name (string)
line 2 is double
line 3 is double
line 4 is double
line 5 is double
line 6 is double

Now how can i write once i click a button, contents of all the files will be read, and loaded into different arrays:
line 1 loaded into array string
line 2 loaded into array of double
line 3 loaded into array of double
line 4 loaded into array of double
line 5 loaded into array of double
line 6 loaded into array of double

And I can access those arrays for searching later in my routine?

Thanks in advance.

Calling exe, opening txt in java

cloudet — Fri, 18 Jan 2008 15:51:12 +0800

I'm trying to create GUI using java.
I tried following codes in action listener of my button, but it just didn't work

» Click to show Spoiler - click again to hide... «

When the filename and its directory are correct, ("C:/programfolder/program.exe") nothing happened when i press the corresponding button.
However, during debugging, i purposely state the incorrect filename, eg: ("C:/programfolder/progrm.exe"), then there is an error caught:

QUOTE

java.io.IOException: Cannot run program "C:/programfolder/progrm.exe": CreateProcess error=2, The system cannot find the file specified

Anyone knows why?
Oh ya, the exe is written in C++.
Thanks in advance.

Virus or window's problem?

cloudet — Mon, 14 Jan 2008 23:43:40 +0800

Hi,
My PC is now facing the strangest problem i have ever encountered. I'm now using my gf's pc to post this thread.
Here's the story goes:

I downloaded some stupid china-made program which claim to be all-in-one pdf convertor (word to pdf, ppt to pdf, html to pdf, jpeg to pdf, blah..blah..blah). Nothing weird until i finished installing the program. The 1st thing i noticed is tat there's no highlight wherever i mouse over my program list. For a normal window, u can pause for a moment to let "Accessories" to pop up its submenu, but mine doesn't.
Then i felt a bit laggy for my pc. So i called up the task manager. I saw no weird process created by me as a user.

The next thing i did was endtask my explorer.exe, I suspected tat mayb it needs a refresh or something. But, still, thing didn't change after a new explorer.exe was called up. Then i tried to restart my window. This is 1st weird thing i noticed: "you do not have permission to shut down and restart this computer". What? Feeling strange and anxious, i pressed the restart button on the pc casing to restart.

After i restarted my pc, more strange thing happened. I could not run my regedit, msconfig, and services.msc. It said there: "windows cannot access the specified device, path or file. You may not have the appropriate permissions to access the item." But i can open my task manager, and processes created by user (me) left only 2- which are explorer.exe and task manager itself! Furthermore, i noticed tat my icons on the taskbar are all gone! Left only connected-network icon. I should have more icons there such as avast, sound control, window live messenger... But they are all gone!

And every single exe i tried to open was failed! Same error message box appeared: "windows cannot access the specified device, path or file. You may not have the appropriate permissions to access the item." This happenned to my mp3 files and video files.

I did go to safe mode, logged in as admin, everything is ok. I deleted the chinese software from the safe mode. And all the regedit, msconfig, and files can be opened.

OK, since there was not extra process running there, i decided to repair my window. I didn't use repair console, but just repair the normal way. After repair, problem still there. And getting worse, my vga driver and sound driver were gone!

I can't printscreen or run any diagnose program now. Here's the list of processes running according to task manager:

taskmgr.exe user
explorer.exe user
svchost.exe LOCAL SERVICE
alg.exe LOCAL SERVICE
svchost.exe NETWORK SERVICE
svchost.exe NETWORK SERVICE
system idle process SYSTEM
system SYSTEM
spoolsv.exe SYSTEM
smss.exe SYSTEM
csrss.exe SYSTEM
winlogon.exe SYSTEM
services.exe SYSTEM
lsass.exe SYSTEM
svchost.exe SYSTEM
svchost.exe SYSTEM
cmdagent.exe SYSTEM
CTSVCCDA.EXE SYSTEM
MsPMSPsv.exe SYSTEM
aswUpdSv.exe SYSTEM
PnkBstrA.exe SYSTEM
ashServ.exe SYSTEM
svchost.exe SYSTEM
ashMailSv.exe SYSTEM
ashWebSv.exe SYSTEM
svchost.exe SYSTEM

I'm not sure is it the virus problem or window problem. Reformat is my last option but i strongly do not want to reformat.
Please note tat i've disabled system restore, and i do not have any ghost CD.

Please help me if u have this problem b4.
Thanks a million.

reading multiple files in loop, please come in

cloudet — Thu, 18 Oct 2007 16:20:32 +0800

Dear all gurus,
Given 30 files, with same format (2 columns, column1 is string and column2 is int. contains thousands of lines) and uniform file name, eg: file1.txt, file2.txt,...,file30.txt,
How can i read it in a loop, and then load them into my 2D array (eg: string words [filesize][maxline], and int numbers [filesize][maxline])?

Tried to use strcat and append but cant work coz the integer i:

ifstream infile;
int indexx;
string st1 = "file";
string st2 = ".txt";
for (int i=0; i<filesize; i++)
{
infile.open(strcat(strcat(st1,(strcat((string)i,st2))),ios::in)
while (!infile.eof())
{
infile>>words[i][indexx]>>numbers[i][indexx];
indexx++;
}
infile.close();
}

That are parts of my data mining project. Every help would be much appreciated. Thanks.
