why get string from redis, will miss blank space -

-

For example:
I get string from command, is an empty space \ x00
127.0.0.1 : 6379 & gt; Get "87102213_87102208" "173275,3915125,10, \ x00"

But in the code in the print log, the empty space is erased. do you know?

log_error ("answer- gt; str:% s, answer-> len:% d", reply-> gt; str, reply-> len);
Answer-> Str: 173275,3915125,10, answer-> lane: 9 / <>

well- X00 is not empty space, it is a null character, which also has string terminator character in C. Most c APIs will use the string as a parameter, but it will be considered that the string closes at the first \ x00 character. Probably this log-in function is included.

However, the Redis Binary is safe, and all the characters are meaningful including placid four. When this value has been inserted, perhaps the size was wrong, so the string was also stored in the form of a null end.

I do not know how to use mysqli_result like in the past. Is this OK? How is right WHERE status = 'popup' and creditsp> = 1 and (CH) from $ res = mysqli_query ($ con, "SELECT` id`,` usrid`, `url` site Lt; cf || cf = 0) sequence by rand () border 1 "); $ Urll = mysqli_result ($ res, 0, "url"); $ Ownerid = mysqli_result ($ res, 0, "Elixir"); $ Citid = mascile_salt ($ res, 0, "id"); Use fetch_assoc on the results: $ line = $ res-> gt; Fetch_assoc (); $ Urll = $ line ['url']; $ Owner = $ line ['nectar']; $ Site id = $ line ['id']; If there are more than one line, then: while ($ line = $ res-> fetch_assoc ()) {// process $ Line}

c# - Textbox not clickable but editable -

I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...
