The name of the event associated with the save as button

Question

Hello, 
 Please I'd like to know the event name which is associaed to the "save as". 
 For example when we open a new file, the SYSTEM_NEW_DESIGN_FILE event is loaded and when we close the dgn file the SYSTEM_UNLOAD_PROGRAM event is loaded so what about "save as".

This may not be an option, however it is typically best to try and work with the software vendor to work out any incompatabilities so they can better understand the situation and possibly accomodate your application workflows. This would provide them an opportunity to make changes or exceptions to help your two applications work better together potentially prevent the need to forceful unload 3rd party applications. 
 Another option to consider would be to perform an "mdl unload AppName" in the initialization of your code and on new design file events. 
 If both options above cannot be utilized you could use an approach similar to the following. 
 Intercept and reject the commands of interest (CMD_SAVE_AS_DWG) as well as (CMD_DIALOG_SAVEAS). Both commands are defined in the header file: cmdlist.h. Each command is respectively activated by - MicroStation "save as dwg" keyin, and MicroStation: File > Save As menu item. 
 Create a MicroStation input queue monitor interest using: 
 mdlInput_setMonitorFunction (MONITOR_ALL, InputQueueMonitor); 
 The user event function prototype should be similar to: 
 Public int InputQueueMonitor ( Inputq_element* iqel /* => Input queue element to validate */ ) 
 Your actions/logic performed by switching on commands of interest: 
 switch (iqel->u.cmd.command) 
 Then choose to return if you want to accept (INPUT_ACCEPT) or reject (INPUT_REJECT) the current command. You may want to add some static variables in your app so that you can detect when you are starting your custom reject of the command, when the next "new" command comes along - so you could possibly reload the app, and execute the unload (and logic) on new design file changes since the 3rd party app may be reloaded as a MS_DGNAPP and running the code above w/o some additional logic write messages to the MicroStation Message Center stating that your app was not able to unload the 3rd party app.

In the MicroStation V8 MDL Function Reference manual (MDLAPIFunctionReference.chm) search for "SYSTEM_FILE_SAVE" and you should see (3) help topics, one labeled "userSystem_fileSave" that provides the prototype and documentation for using this event type for the function mdlSystem_setFunction. Here a prototype from some of my code: 
 Public void OnFileSave 
 ( 
 ProcessChangesWhen	when, 
 DgnFileChangesFlag	changesFlag, 
 DgnSaveReasons	reason, 
 double timestamp, 
 DgnFileObjP	pFile 
 ) 
 Then retrieve the DgnFileObj file name similar to.. 
 ... 
 char strFileSpec[MAXFILELENGTH+1]; 
 memset (strFileSpec, 0, sizeof strFileSpec); 
 dgnFileObj_getName (pFile, strFileSpec, sizeof strFileSpec); 
 ...

Unknown said: Using the SystemFunc_FileSave callback function, where can I find the name of the new file and his extension 
 The last argumnent of your callback function is a DGN file pointer ( DgnFileObjP ). You can use that to obtain various information about that DGN file. Unfortunately, the relevant function is not published in the SDK, but Keith Bentley kindly provided the prototype... 
 // [Keith Bentley] // Use either (I'm not sure why they're not in the public header files): Public void dgnFileObj_getName ( DgnFileObjP pDgnFileObj, // => File pointer char* pFileName, // <= store name here int maxLen // => length of pFileName ); //or Public MSWChar const* dgnFileObj_wGetName ( DgnFileObjP pDgnFileObj // => File pointer );
