com - PHP, calling a ADO object method that has optional parameters -

-

I have found the original set of assisted works to reach ADO through almost PHP I'm running into a problem When trying to perform an archived procedure with the adExecuteNoRecords option set for $ cmd-> Execute (; adExecuteNoRecords);

I have tried to tap for the first two parameters, new variants (new), new variant (null), new variant (VDETPT), etc ...

I either A "Parameter 1 can not be passed from context" or type-mismatched comm-expansion, and -> Execution (, adExecuteNoRecords) does not pass PHP parsing.

I did a lot of searching, but I have not found an example of anyone using it.

If there are optional parameters while calling a COM object method in PHP, then how can you not set the initial parameter to anything?

Thank you.

replace the optional parameter $ missing = new variant (VT_ERROR) Try.

In Btw, COM params, there are still types, if there is an optional Ultimate BSTR then except this, it is usually to pass an empty string. What may seem strange is that the default value for the optional paragraph is specified in the Type Library. To wit. An optional BSTR param can have "abc" default value. So before creating a call in PHP, you should research it. In your special case, there are 3 optional variant paramics in the execute without specific defaults, so we use VT_ERROR to make VARIANT param disappear.

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...

kernel - How to create a "Block device" in Windows -

-
For people familiar with Linux, it is possible to create a module and register it as a block device. This allows the user to mount it as a regular disk (whereas all block I / O is controlled by the module, for example USB-MastStorage). Is there a way to do this in windows? (Windows needs to create a volume. Raw data will come from the interface with justification.) Thanks The easiest way (and this is not easy!) Is to write one, you can do it also with KMDF. The latest issue of the "NT Insider" of the OSR is an article in how to do this, but it not is going to be easy anyway You will learn a ton, though, So if you are interested in kernel development, then this is a good way to start!
