vb.net - Access to the path "......." is denied? -

-

i have windows form application loads datagridview. in 1 of columns hyperlinks image files. when these links clicked code shown below runs open image. however, have new user on system has issues viewing of images.

at first found user did not have access 1 of subfolders in image path. after corrected, user can access full image path , view images through windows explorer.

however, when running application , clicking hyperlinks, user receiving:

error: access path '\\server\folder1\folder2\folder3\image.tif' denied. in procedure: fqimagingfiltereddatagridview_cellclick

any ideas going on? user has full rights directory, individual rights, , can view images through windows explorer, application still treats user denied.

here code:

private sub fqimagingfiltereddatagridview_cellclick(byval sender object, byval e system.windows.forms.datagridviewcelleventargs) handles fqimagingfiltereddatagridview.cellclick     try         if e.rowindex = -1 exit sub         if e.columnindex <> 0 exit sub         dim imagefile string = fqimagingfiltereddatagridview.currentrow.cells("filepath").value.tostring & "\" & fqimagingfiltereddatagridview.currentrow.cells("filename").value.tostring          if not io.file.exists(imagefile)             msgbox("image file not found - unable display!", msgboxstyle.information, "attention!")             exit sub         end if          ' pass memory stream version of image imageform         dim displayimage image = loadmemoryimage(imagefile)         if not isnothing(displayimage)             using imagedisplayform new imageform(displayimage, imagefile, true)                 imagedisplayform                     .text = imagefile.substring(instrrev(imagefile, "\"))                     .showdialog()                 end             end using         end if      catch ex exception         msgbox("error: " + ex.message + "  in procedure:  " + miscellaneous.invokedby(), msgboxstyle.information, me.text)     end try end sub

any assistance appreciated.

java - Copying object fields -

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
