vba - Print to POS Display Unit -

-

I have an Epson display unit (for sale point), and it is set as a printer when I I want to go to the printer properties> font (there is a test input box), so I can get it to print.

However, there is no result of printing from an app such as Notepad's yield, I call it P.O. I'm trying to work with. App created in Excel I found a COMM Port communication script, but I can not find the Open command that "File in use" I would like to know that someone else has had experience with this kind of thing.

Under the assumption that your printer is connected to serial interface 1, provided the serial interface parameter is set correctly , And you want to send a string of letters in that interface, you can try it ...

# 1, to turn off "ddd", turn off # 1 Closing the sub code

Paste this code into an Excel VBA script and open it via the circle "COM1:" Open "COM1:". F8 - This worked for me

You can replace "COM1:" by any existing "comx:" or "LPTX:" (do not forget the semicolons!)

< P> I am using it to set the amateurs radio (setting frequency) to control the broadcast station names and their frequencies in the Excel table. I'm definitely sending special characters using the chr () function for my gear.

The macro is tied to a control button, my Excel office is 2003 (it's already working in Office97)

MySql variables and php -

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

Which Python client library should I use for CouchdB? -

-
I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
