marshalling - C# DLL extern prototype help -

-

I have a CDLL with the export that looks like the following: 

  __ declspec Dllexport) int function (four * password, unsigned char * ssid, int ssidlength, unsigned char * output) {/ code>

On the C # side, I am using this type like this :

Something like this:
C => C #
Four * Myarvers => [Marshall AS (unmanaged type) .PSTP)] string myVAR


All types list of?

I ask, because I never know when "referee" or out or when ITPT is used, or how Marshall should do something as something

Finally, In the above code, I am marshning an indicator as a long indicator for a string for an unsigned four array. It does not seem right, but it works for it to finish in a byte [] array, it makes more sense, but I can not get it to work if only there is an online reference which I

There are so many guides on MSDN

This Being said, and there are great resources to work with native code.

Interop assistant, in particular, often makes it very easy.

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for.

With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
