Convert A Unicode Text File To ASCII
I'm trying to read a text file into visual basic, change a part of it, and write it back out a text file. I had been having problems using OPEN (always resulted in an error 36), even though I had tried using LOF and EOF.

I found that the problem was the text file that I am trying to read from is in Unicode. Is there an easy way to convert this text file into an ASCII text file before I read from it?

UTF8 Text Boxes
I maintain a user data management tool that is written in VB6. This is an application that is starting to be used worldwide and so needs to support multiple character sets using UTF8. I have asked a few dev collegues of mine and they all say it needs to be ported to .Net but I am not sure this really is an option due the where the program has to sit. So if anyone has some suggestions to try and get text boxes to support UTF8 characters it would be great.

Thanks,

Help With Converting (UTF8, Hex, ASCII)
Hi, I'm not exactly sure whats wrong with the following code, but I have been trying for a bit now to get the syntax correct. The error I get is an "expected array" error if that is of any help. I have a frmConvert that has a txtbox and a lstbox. The user places the text they wish to convert in the txtbox and selects the conversion (e.g. - UTF8, Hex, or ASCII) and hits a cmdConvert button which should display the converted text back into the txtbox. Here is the code below.


private Sub cmdConvert_Click()
on error GoTo ConvFailed
If txtConv.Text = "" then
Exit Sub
End If
If lstType.ListIndex = 0 then txtConv.Text = Converting(0).ToHex(1, 0, txtConv.Text, 0)
If lstType.ListIndex = 1 then txtConv.Text = Converting(0).ToUTF8(1, 0, txtConv.Text, 0)
If lstType.ListIndex = 2 then txtConv.Text = Converting(0).ToASCII(1, 0, txtConv.Text, 0)
ConvFailed:
MsgBox "Conversion Failed"
End Sub

public Sub Form_Load()
lstType.AddItem "=> Hex"
lstType.AddItem "=> UTF8"
lstType.AddItem "=> Regular(ascii)"
End Sub




If there is any more required code that you may need from me to understand my situation better, then just reply stating what it is you need. I would greatly appriciate any help you can give. I believe the error is in the syntax of "Then txtConv.Text = Converting(0).ToHex(1, 0, txtConv.Text, 0)". Thanks in advance for all your thoughts/suggestions/help.

Sorting Data From An ASCII Text String And Saving It As Text File
Hi,
I'd first like to copy paste a section of my ASCII text string over here and then ask the question.Given below is the ASCII text string:

RT 01 A_UNIT
DEV 01 A_UNIT

=ontrol Mode ON LOCAL STAT
Occupied YES OCC
CCN Chiller START CHIL_S_S
Alarm State Normal ALM
Active Demand Limit 100 % DEM_LIM
Override Modes in Effect YES MODE
=
=?
RT 01 CIRCA_AN
DEV 01 CIRCA_AN

=IRCUIT A ANALOG VALUES
Percent Total Capacity 100 % CAPA_T
Percent Available Cap. 100 % CAPA_A
Circuit Running Current 185 AMPS A_CURR
Discharge Gas Temp - A2 122.9 dF DISTMPA2
Saturated Condensing Tmp 97.5 dF TMP_SCTA
Saturated Suction Temp 41.5 dF TMP_SSTA
EXV % Open 43 % EXV_A
Variable Head Press Pct. 0 % VHPA
=
=?

Given above is a portion of my ASCII text string.I'd like to know how to sort out the data from this file and copy it in the same format as given above into a new Text File,using the delimiting characters like the white space and the "?".The "?" indicates the end of the file and the following ASCII text string after every "?" indicates the start of a new text file.

I'd be very very grateful to the person who'd give me the solution to this.Thanking you in anticipation.

Convert Rich Text To Plain Text Without Using Rtf Component
Greetings all!

Here's my problem:

I have some text that is saved in a database and it is in RTF format.
But now, what I need to do is convert all this into normal, plain, and boering old text...

So anyway, is there a way to convert RTRF into plain text without using the Rich TextBox Control?

Thank you all, and have a good day!

Using A RTB: How To Convert RTF Text Into Plain Text During Run Time??
My Werdpad text editor, I want to add a feature I can't seem to figure out how to do.

With a new file I "paste" a bunch of text from something... it's all formatted nice and pretty in rich text. Tables, Bold...etc.

What I want is by selecting an option from the menu to take what is displayed and reformat it to plain text (as if I pasted it into notepad) getting rid of all the formatting (including table cells if there are any).

I know how to set the font using SelStart=1 and SelLength = Len(RTB.Text)
But I don't know how to get rid of tables and pictures....

Any idea's is appreciated.

Thanks

Edit: Here is all I have. This sets the font. But that's all I have

Code:
Private Sub mnuPlain_Click()
Text1.SelStart = 1
Text1.SelLength = Len(Text1.Text)
Text1.SelFontName = "Verdana"
Text1.SelFontSize = 10
Text1.SelBold = False
Text1.SelItalic = False
Text1.SelUnderline = False
Text1.SelStrikeThru = False
Text1.SelColor = 0
Text1.SelStart = Len(Text1.Text)
End Sub
Yes, my RTB is called Text1 I am just used to that name for a text box.

Want To Convert Text In Text Boxes To Normal (without Text Boxes)
Hi all,

Our Client is sending files in RTF Document format which has some content. Each and every word in that document is in its own text boxes (i.e., the RTF has full of text; each and every word is in own text box). I need to convert it to normal word document without text boxes. But my problem is the entire content of that file is coming in text boxes. so it is very difficult to convert it to normal word document (without text boxes).

Currently I have two choices to do that: one is select the text box and copy the content and paste it in a new file. but all formatting is lost. i have to do all formatting manually. The second option is convert it to PDF and do a conversion and check alignments give some missing formatting etc.

These cases are ok if I got a file with full of text paragraphs. but most of the time I am getting tables. That time these ways are not smart way to do that.

Is there any other way to convert that file to normal word document. Pls let me know.

Currently I used to convert that document to Adobe PDF and will do a PDF conversion and then I will do a formatting as per the RTF document.

So, it is taking to much of time consuming and effort.

Is there any solution for this?

Thanks!

Ascii To Text
i didnt want to clutter the board and since this question relates i just posted it here. ok well here is where im at. im trying to convert the ascii code back to text. here is how i have it set up.5 text boxes and 2 command boxes the first text box is where the user imputs their message the user presses command button number 1 and that converts text to ascii and posts the ascii in text box 2this is easy no problem now the third text box i call the shifter because it takes what ever number they imput in it and that shifts the ascii up or down that many times also no problem as of now now when the user presses command box number 2 it is suppose to take the shifter and shift the ascii code that many times over which it does and then it is suppose to convert the newly made shifted ascii code back to a new text. example user enters hi converts to ascii 104 05 then user enters +1 for the shift presses convert to text in text box 4 it says 105106 and the new word says "ij" because thats the shift. again my probelm is the changing 105106 to ij im gonna post my whole code so far everything works sept for the bottom

Ascii To Text How ?
Hi guys , there's any way to convert Ascii to text ?

thanks for reply

Ascii Text
I would need a

control for displaying and editing ascii text like in edit.com or other console apps.

or if not then

code for converting between ascii text and some sort of text with escape characters representing those characters the textbox control doesn't display lik e vbnullchar and vbcrlf, vbtab and so on.

or if not then

a list of the characters that doesn't display in a textbox

Ascii Only In Text Box
Ok, I want to type letters and numbers on the key board and
have the ascii code come up in the text box, instead of text.
This is as close as I can get:
_______________________________________________
Private Sub Text1_KeyPress(KeyAscii As Integer)
Text1.Text = Text1.Text & KeyAscii
End Sub
________________________________________________
The "Text1.Text & KeyAscii" was just to get sequential characters in the text box.
Notice that:
mike becomes, ekim109105107101

Three problems:
1) If I type the word "mike", it comes out backwards(ascii included).
2) I only want ascii not letters and not in reverse order.
3) Things get worse when I try to use the "enter" key.

If you create a simple textbox and cut and past the above code, you will see exactly what I mean.

Thank's for any help!

Ascii Value Converted To Text
how do you make a Textbox show the value of an Ascii value? ... i want it to display a " (ascii 34)

it checks if it doesn't end with a " after the lost focus and then it places it there but i can't say Text1.text = Text1.text & """

i've had similar problems like this so please don't give me me alternatives

ASCII Text Header
Is this header a fixed or variable length header? Meaning:

Will byte 80 always have the value you want?
Take BITPIX for example. If 16 / 16 = 1 Then Len(BITPIX) = 1, but if 16 / 1 = 16 Then Len(BITPIX) = 2

Is NAXIS1 always going to be where you expect it? Or will it vary depending on the information in the header, much like the ID3 frames in an MP3 file?

What Are These Ascii Values As Text?
What is Asc(5)?
What is Asc(12)?

These codes are used as an end of transmission code with the data I am using and I need to know what they actually are.

Ascii Text Compression
Anyone know of a way of compressing a load of text, without the resulting 'data' containing any CR/LFs ?

The reason I ask is because I want to include a large amount of data in an app im making, (about 600K), and I dont want to put the data into a file.

So I wanted to hardcode the compressed the data into the app, and then have it decompress the data at runtime.

Any ideas ?

How To Tell If A File Is Ascii Text Format
Hello,
I am making a simple file viewing demo, which will display the contents of a text file in a multi-line textbox from a file selected in a directory listing. I only want to open the file if it is in "plain text" format - so files like .txt, HTML files, VB files like .frm, .vbp, and .cls would qualify but .frx would not; .exe, .xls. etc. would be excluded as well. (In the case where a non-text or binary file was selected, the multiline textbox would simply display "File is not in text format" or something to that effect.)

Without relying on the file extension, is there a way to test the file to say with reasonable certainty that it qualifies as a "plain text" file? I'd appreciate your thoughts ...

Ascii Character Set Functions In Text Boxes
Help!!

I am trying to edit some text in a text box by using the ascii codes for the editing functions i.e. chr(8) for delete etc, at the moment when i write the following:

textbox.text = textbox.text & chr(8)

instead of deleting the last character a black rectangle appears, which i guess means the the command is being written as its character rather than its function.

How can i get over this problem??

ps i also want to use the controls for tab, shift, shift lock and the other general keyboard function keys.

Replace Text With Full ASCII Code?
does anyone have that code that will replace everything in data.txt with it's ASCII code? or a function that will do it? Something like this:

Private Function ASCII(data As String) As String
data = Replace(data, ">", "%3E")
data = Replace(data, "`", "%60")
data = Replace(data, "{", "%7B")
data = Replace(data, "|", "%7C")
data = Replace(data, "}", "%7D")
data = Replace(data, "~", "%7E")
data = Replace(data, ":", "%3A")
data = Replace(data, ";", "%3B")
data = Replace(data, "<", "%3C")
data = Replace(data, "=", "%3D")
data = Replace(data, Chr(34), "%22")
PostASCII = data
End Function

I dont think i can find all the ascii. does anyone have it done already?

Read Only Last Line Of Text/ascii File
Hi Guys,

I needed some help regarding file reading in VB 6. I am writing a program that needs to insert a record in a text file. The text file has following format..

Date, Time, Open Price, Close price

Now i need to insert record only if date is greater than last date in file.

So everytime I need to insert record, I have to open file and read sequentially and then I reach last record. This takes time.

IS there a way to read such file in binary or whatever so that i can get last record straight away or very quickly without going thru all records one by one.

If there is can anyone post a small code.

[Records in the (text) file is like -

01/01/2006, 1100, 123.33, 155.55
01/01/2006, 1130, 122.22, 134.33
01/01/2006, 1200, 112.22, 124.33
so on ... ]


Thanks a lot,

How To Convert &"TEXT&" To TEXT? Remove The Quotations?
I have a text file that I load into a list box(seems easier to search and use index to reference items in list).

It starts out like this:

begin general_information
&nbsp name "Example"
&nbsp designer "Steve McNally"



I need to get rid of the quotation marks from both sides of the word "Example" and "Steve McNally".
I can get rid of the mark on the left with Mid (String)

txtName = Mid(List2.List(1), 9) wich produces: Example"
txtDesigner = Mid(List2.List(2), 13) &nbspproduces: Steve McNally"

I've tried mixing the Mid function with the Left and the Right functions, but get odd results like: ample""Ex

Then, I'm going to print it back to a text file, but I'll be able to Print the " " back around them no problem.

I'd appreciate any help. I'm still kind of a novice so, if you could just paste some code please.
