What people consider ASCII and Hex with strings varies so much, you pretty much need to supply an example. The best way is to create a VI with default data in the string control and indicator (to show what you want out).

How could I choose some bytes from HEX string and then convert it to a decimal value?

Hi I am working with an OMRON E5EN temperature controller using VISA serial to get data, I send the Read from Variable Area command and get this string in hexa 0230 3130 3030 3030 3130 3130 3030 3030 3030 3030 3041 3203 71 or .01000001010000000000A2.q in ASCII this string means:
02 STX
3031 3030 Node and subadress
3030 End Code Normal Completion
3031 3031 Command Read from Variable Area
3030 3030 respt code Normal completion
3030 3030 3030 4132 Hexadecimal A2 = 162 (this is the temperature data that I want to show in decimal)
03 ETX
71 Block Check Character
I want to choose the eight bytes for the temperature data and convert it to a decimal number. I have seen the examples to convert a Hexa string to decimal but I do not know how to choose the specifics bytes that I need.
I have look for a driver but i didn´t find any. I am a beginner so please include especific topics for me to study in your answer.
Thanks

If the response always has the temperature starting with byte 15 and is always 8 bytes in length, you can use the String Subset function to get those bytes out of the string. Then use Hex String to Number to convert to a decimal number.
Well someone already beat me to the solution:

Conversion from a string to date type

I am trying for a servlet application , for which the requirement is as under :
from a html form through a input type text field , a date in string format , say 12/25/01 , is picked up.
this date is received in the servlet code , and is required to be updated in Microsoft Access Database Table under a field of data type "Date/Time"
here the problem is , the date's existing data type is String and the Access' field's Data type is Date/Time , therefore, it needs to be suitably converted to a date format before it is put into a sql statement .
please help , if any functionality is available for a conversion .
thanx and regards

yes stephen , taking a tip from you and another from a post from this forum yesterday on SQL Exception , i shifted my focus to java.sql.Date ,
now modifying my code as under works with perfect perfection ,
thanks stephen and joe schell for all the help

From MD5-string to byte array

Hi fellows, I'm writing a simple cracker for MD5. The hash value has to be passed at command line as argument.
e.g.
java Cracker 0cc175b9c0f1b6a831c399e269772661In order to decode the hash value I'm using a brute force approach: therefore I compare a series of strings with the hash value by using the method of the class MessageDigest isEqual(byte[] a, byte[] b). So I encode each string and compare the byte array I get with the byte array of the hash value.
Here it comes the trouble I'm in:
when I try to get a bytes array of the MD5 hash value passed as argument of the program , I do get something, but it's not something that the isEqual method of MessageDigest can use to compare. As a result any attempt during the execution of brute force fails, even though the key is one of the string being checked.
Perhaps am I facing a format problem? Any idea?
Sorry for my english, it's not my first language
Thanks to whoever will help

Almost all questions in these forums about brute force attack on MD5 (or SHA1 or SHA256 etc etc etc) are school, college or university projects and of no practical use. This is almost certainly such a project.
Unless things have changed in the last year, there is no practical brute force attack on MD5 whereby an input can be generated from an arbitrary output even though two inputs with the same output can be fabricated. A dictionary attack is feasible if no salt is used or a known salt is used since one only has to build the dictionary for one salt value. If a different salt is used for each entry being attacked then a dictionary will be need for each salt being used. Of course if one takes the simple precaution of not using anything that is likely to be in a dictionary then the dictionary attack will likely fail.

How can I convert/read out from a string Hex (8-bit), the bit 0 length 1

How can I convert/read out from Hex (8-bit), the bit 0 length 1 (string subset!!??) and convert it to decimal.
With respect to one complement and two complement ?

Just like Jeff, purely guessing here.
It almost sounds like you just need to Read from Binary File?
AND the 8-bit number with 1?
Need more details. What exactly do you have to start with? What exactly are you trying to get out of it? Examples help.

Conversion of String to byte[ ]

Hi everybody
I have a Byte[] value in one of our client database it seems like this -- 00033DB7FB87EC4EB371BCC9D3BF13EC
when they import into CSV it became String
I need to Dump into my database what ever you see in that Byte[].the value is already a conversion only so i need to dump as it is.
now the real problem is how to convert the same String as Bytes
if i use String.getBytes() it exceeding the Field Length
my filed length in the database is Binary (16)
Plz do the needful
Thanks for ur Help in advance

So System.out.println(theString) results in "00033DB7FB87EC4EB371BCC9D3BF13EC"?
Then .getBytes() is not what you need. It will get the bytes representing this unicode string in a specific encoding (such as ISO-8859-1, UTF-8 or the like).
You need to parse to digits each as hexadecimal numbers (using Integer.parseInt() for example, don't forget to specify the radix 16) and convert that to a byte[] array (the length of the byte array should be half the size of the String).
Warning: because Java knows only signed ints, you'll have to jump through some hoops to get the correct value. Assuming String a contains 2 hexadecimal digits, you get the byte value like this:
byte b = (byte) (Integer.parseInt(a,16) & 0xFF);

Which bytes should be edited in a WMF hex string stored in an RTF file in order to change image dimensions?

I would like to save the WMF file with proper dimensions as they are in the editor (my saved WMFs have the dimensions of my screen resolution). They come from a RichEdit.
Thanks.
Edit:
My goal is to convert the images that appear on a RichEdit to another format.
Here is the fragment of the RTF:
{\pict\wmetafile8\picw7407\pich9259\picwgoal4199\pichgoal5249
010009000003703e020000005a3e02000000050000000b0200000000050000000c022b24ef1c5a
ffffffffffffff030000000000
}\cf2\lang1033\b\f1\fs23\par
For each 2 chars in this string I converted it to hex and saved it through a memory stream. Then I opened it in Paint or GIMP and there is the image. I even can convert it to a PNG file through ImageMagick tool. But the dimensions are wrong. How to fix
this?
I am using Lazarus.
I could guess that the header is not OK, but how they can be opened by Paint and converted? So I guess the dimensions info is wrong in the header. In GIMP even the dimensions are right, here a link to the GIMP's dialogbox confirmation with the dimensions
it has encountered in the file ( http://s13.postimg.org/s536tgo9z/Metafile_in_GIMP.png ).
So the info is there, but is wrong. When I open the images in Paint, they are wrong. Microsoft Office Picture Manager can also open them correctly, but could not convert them so. I need to do it programmatically. TMetafile Delphi class could not open these
files as well in order to be converted. So I could only edit the bytes.
My RichEdit WMF data can not be accepted by ComputeAldusChecksum routine nor get a handle from SetWinMetaFileBits API call, which would convert it to an EMF format.
procedure TMetafile.ReadWMFStream(Stream: TStream; Length: Longint);
var
WMF: TMetafileHeader;
BitMem: Pointer;
MFP: TMetaFilePict;
begin
NewImage;
Stream.Read(WMF, SizeOf(WMF));
if (WMF.Key <> WMFKEY) or (ComputeAldusChecksum(WMF) <> WMF.CheckSum) then
raise EComponentError.Create('Invalid metafile.'); // <<<<<<<<<<<<<<< exception here
Dec(Length, SizeOf(WMF));
GetMem(Bitmem, Length);
with FImage do
try
Stream.Read(BitMem^, Length);
FImage.FInch := WMF.Inch;
if WMF.Inch = 0 then
WMF.Inch := 96;
FWidth := MulDiv(WMF.Box.Right - WMF.Box.Left,25400,WMF.Inch);
FHeight := MulDiv(WMF.Box.Bottom - WMF.Box.Top,25400,WMF.Inch);
with MFP do
begin
MM := MM_ANISOTROPIC;
xExt := 0;
yExt := 0;
hmf := 0;
end;
FHandle := SetWinMetaFileBits(Length, BitMem, 0, MFP);
if FHandle = 0 then
raise EComponentError.Create('Invalid metafile.'); // <<<<<<<<<<<<<< exception here
Enhanced := False;
finally
Freemem(BitMem, Length);
end;
end;

Paddy,
There are a couple of ways to create a Word file. One is to use the Report Generation Toolkit which includes vi's to create and edit Word documents. Since you are associated with a university you may already have the toolkit. The other way is to use ActiveX. You should be able to find examples of both in the forums. There may also be an example that shipped with LV.
Here is one example to get you going http://zone.ni.com/devzone/cda/epd/p/id/992

Conversion from string "" to type 'Double' is not valid

We're using BPC 7.5 MS and on patch level 111.02
There's two front-end servers and one back-end. we have about 100 users but concurrency is likely in the 50 range.
We've been running extremely well for about 4 years but are now starting to run into problems.
There are about 5-6 applications but none greater than 10 million records. We optimize regularly.
However over the past two months admin processes seem to take a lot longer. Optimization now times out after about 1.25 hours and none used to take greater than 15 minutes.
Today after processing dimensions we checked the application status and we were not able to check if it was available or not. We got a pop up box saying
conversion from string "" to type 'Double' is not valid
I've processed dimensions and applications since and still this error persists.
We're attempting a reboot to see if that helps but I've never seen this before and in combination with the slower admin processing I'm wondering if there's something drastic going to happen.
Michael

Hi Michael,
for the poor performances you have to check the guides about performance on bpc if you have scheduled regurarly optimize during day and night (just verify that never factwb reach 50.000 and fac2 500.000 records) maybe you need to change some parameter on the server as MaxThreads.
For the conversion string error on admin console see please this note 1803092 - Set application set status error

Deprecated conversion from string constant to 'char*'

Hi all
I am working with strings and i cant figure out why the following
warning appears at time of build.
warning: deprecated conversion from string constant to 'char*'
It appears for the line
char *myName = "Apple.txt";
Is there anyone who can help me?
Help is welcome.
Thanks in advance.

Any reason why you aren't using NSString in place of char?
char *myName = "Apple.txt";
NSString *myName = @"Apple.txt";

Conversion from string "20041023 " to type 'Date' is not valid.

Hi ,
I have a table with one of the column(EmpHiredate) datatype is char(10). It has value like "20141023". I need to display this value as date format(dd/mm/yyyy) in report.
Following methods i tried in textbox expression but no luck.
=Format(Fields!EmpHireDate.Value,"dd/MM/yyyy")
=Cdate(Fields!EmpHireDate.Value)
Error:
[rsRuntimeErrorInExpression] The Value expression for the textrun ‘EmpHireDate.Paragraphs[0].TextRuns[0]’ contains an error: Conversion from string "20041023 " to type 'Date' is not valid.
Is it possible to convert string to date using SSRS textbox expression ? Can anyone help me with the solution.
Thanks,
Kittu

Hi Jmcmullen,
Found one more issue on the same. I have one value like "00000000" for the column(EmpHiredate)
, when i use above expression values(ex:"20141023")
are displaying in dd/MM/yyyy format in report except value like "00000000" and giving following error:
[rsRuntimeErrorInExpression] The Value expression for the textrun ‘EmpHireDate.Paragraphs[0].TextRuns[0]’ contains an error: Conversion from string "0000/00/00" to type 'Date' is not valid.
Even i tried to pass its original value("00000000") as below but no luck.
=IIF(Fields!EmpHireDate.Value = "00000000","00000000",Format(CDATE(MID(Fields!EmpHireDate.Value,1,4) + "/" + MID(Fields!EmpHireDate.Value,5,2) + "/" + MID(Fields!EmpHireDate.Value,7,2)),"dd/MM/yyyy"))
Also tried this:
=IIF(Fields!EmpHireDate.Value = "00000000","2000/10/21",Format(CDATE(MID(Fields!EmpHireDate.Value,1,4) + "/" + MID(Fields!EmpHireDate.Value,5,2) + "/" + MID(Fields!EmpHireDate.Value,7,2)),"dd/MM/yyyy"))
Please Suggest.

Hi,
The above error appears due to date format is differnt from SAP query generator and SQL server.
So you need convert all date in above query to SQL server required format.
Try to convert..let me know if not possible.

You can search the forums for that error message and find previous discussions - they all boil down to the same problem. Somewhere in your query that calls this function, the code invoked implicitly converts from string to date/datetime. In general,
this works in any version of sql server if the runtime settings are correct for the format of the string data. The fact that it works in one server and not in another server suggests that the query executes with different settings - and I'll assume for
the moment that the format of the data involved in this conversion is consistent within the database/resultset and consistent between the 2 servers.
I suggest you read Tibor's guide to the datetime datatype (via the link to his site below) first - then go find the actual code that performs this conversion. It may not be in the function you posted, since that function also executes other functions.
You also did not post the query that calls this function, so this function may not, in fact, be the source of the problem at all.

How to parse out curly quotes from a string

Hi,
I am writing a web application, where people will be copying from a Word Document into a text area. Then I get a String from the parameter passed.
How can I parse out curly quotes and mdashes from this String? Are there specific character codes that I can parse out to replace them with regular quote characters or html quote characters?
Thanks,
Gabe

Interesting problem and one that we had to deal with a couple of years ago. I think you might be talking about smart quotes and these are actually control characters used by MS products. They show up as squares in HTML unless properly dealt with. Try downloading some UNICODE charts to find out the values of these characters. I think they are something like 0044 and 0042 but I cannot remember off hand.
