    <p>I want to compile some c++ code to a dll at runtime using c#. Is that possible? And how do I proceed? Is it possible to simply translate the c++ code to c#? I am new to c++ and do not know if it is even possible. The dll is used in an other application, thus the input and output for the dll is fixed and can not be changed.</p> <p>I have been looking at cppcodeprovider, however, I does not seem to work.</p> <p>Would it be possible to build a c++ wrapper for c#?</p> <p>Here is the c++ code that I want to compile at runtime:</p> <pre><code>#include &lt;stdio.h&gt; #include &lt;string.h&gt; #define NINT(a) ((a) &gt;= 0.0 ? (int)((a)+0.5) : (int)((a)-0.5)) extern "C" //avoid mangled names { void __declspec(dllexport) __cdecl cDISCON(float *avrSwap, int *aviFail, char *accInfile, char *avcOutname, char *avcMsg); } //Main DLL routine void __declspec(dllexport) __cdecl cDISCON(float *avrSwap, int *aviFail, char *accInfile, char *avcOutname, char *avcMsg) { char Message[257], InFile[257], OutName[1025]; float rTime, rMeasuredSpeed, rMeasuredPitch; int iStatus, iFirstLog; static float rPitchDemand; //Take local copies of strings memcpy(InFile,accInfile, NINT(avrSwap[49])); InFile[NINT(avrSwap[49])+1] = '\0'; memcpy(OutName,avcOutname, NINT(avrSwap[50])); OutName[NINT(avrSwap[50])+1] = '\0'; //Set message to blank memset(Message,' ',257); //Set constants SetParams(avrSwap); //Load variables from Bladed (See Appendix A) iStatus = NINT (avrSwap[0]); rTime = avrSwap[1]; rMeasuredPitch = avrSwap[3]; rMeasuredSpeed = avrSwap[19]; //Read any External Controller Parameters specified in the User Interface if (iStatus == 0) { *aviFail = ReadData(InFile, Message); //User to supply this routine rPitchDemand = rMeasuredPitch; //Initialise } //Set return values using previous demand if a sample delay is required avrSwap[44] = rPitchDemand; //Main calculation //User to supply calcs routine if (iStatus &gt;= 0 &amp;&amp; *aviFail &gt;= 0) *aviFail = calcs(iStatus, rMeasuredSpeed, rMeasuredPitch, &amp;rPitchDemand, OutName, Message); //Logging output - example avrSwap[64] = 2; //No of outputs iFirstLog = NINT(avrSwap[62])-1; //Address of first output strcpy(OutName, "Speed:A/T;Pitch:A"); //Names and units avrSwap[iFirstLog] = rMeasuredSpeed; //First Value avrSwap[iFirstLog+1] = rMeasuredPitch; //Second value //Return strings memcpy(avcOutname,OutName, NINT(avrSwap[63])); memcpy(avcMsg,Message,MIN(256,NINT(avrSwap[48]))); return; } </code></pre>

    1. CO`Is it possible to simply translate the c++ code to c#?` No, don't even bother. You would lose accuracy, and the languages are different. You could port it yourself, but not automaticly.

    2. COThe answer to each of the questions is yes, but you really need to clarify what you want to achieve OR learn. Options you've listed require completely different answers.

    3. CO@gunr2171 - it is not *practical* in most cases to automatically translate C++ to C#, but theoretically possible :).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
