I think u dint got my question right. I have updated the question with further explanation if u could plz have a look. Rahim Rattani Karachi - Pakistan

Consider a library (unmanaged) exports a class. the class is as follows. class A { public: virtual void funcA() { //do something } void DoProcessing() { // Do stuff funcA(); // Do Stuff } } Now in native, If i have to override funcA it would be as class DA : public A { public: virtual void funcA() { // related processing here. } } Now if i create an object of DA, and call DoProcessing() , funcA() in DA would be called. Now if I write a managed wrapper over class A as class _gc MngdA { private: A __nogc* m_pA; public: void DoProcessing() { m_pA->DoProcessing(); } } No if I inherit from MngdA, i dont have any path to override the virtual functions. This means DoProcessing() will always call the funcA() in class A. I need a mechanism, so that this virtual function call from the native could could be riuted out into managed code and be able to override it from clr languages.

I am working on an applicaiton that needs to support different databases. I created the reports using SQL Server as the database, and for others i am setting the databse information and table locations from the code. Now in some of the reports i have got subreports, having parameters mapping to the fields in the main report. Since the parameter is defined with an '@Parameter' in sql server and ad 'Parameter (no @)' in oracle for stored procedures I had to change the name of the parameters from code too. This is working ok. Now the problem is that I had to modify the links accroding to the new parameter field names. but the problem is that i am unable to retrieve the mapping field names of the subreport. There is a call available as ISubreportLinkPtr->MainReportField->GetName ISubreportLinkPtr->SubreportField->GetName The main report one return the correct name of the field in the main report but the subreport one always returns the first database field instead of the actual mapping field. Anyone got any idea please reply quick. Thanx. Rahim Rattani Software Engineer, Matrix Systems (Pvt) Ltd., Karachi - Pakistan

You seem to have declared the function sumarray(...) but forgot to implement it. Rahim Rattani

I think you want to read in the standard cosole. If I am correct, then u can do this by simply open a socket at port no. 512. anything u write would be sent to standard console for output and anything that is typed at the console would be available for u to read on the socket. 512 is a port that open to the standard console.

Yes, new and delete operators can be overloaded. Use the following signatures. 1.) new :- void* operator new( size_t p_stBlock ); 2.) delete :- void operator delete( void* p ); Rahim Rattani Software Engineer, Matrix Systems (Pvt) Ltd., Karachi - Pakistan

I am using PJ Naughter's CNTService for the purpose. The example service provided by him works fine. But when I try to use his frmaework for my own service application, the service creation works fine but start service always fails with the error 997: overlapped IO operation in progress. Any help plz. Rahim Rattani

try using as template<typename T> inline const T& getMax ( const T& a, const T& b) { return a < b ? b : a ; } The problem is with the name of the function. I have renamed it from "max" to "getMax" because macros with the name "min" and "max" already exist in stdlib.h, and same name of the function as those macros caused the errors.

The problem in your code is that u are writing the file after the do while loop, and therefore if u write the file after the do-while construct it would write the last values. Write the values to the file in the do-while loop. After every time you obtain the values from the user write it to the file and then ask for the y/n thing. I mean just before this cout<

Yes it does creates the file, if the file does not exist. The actual syntax is file.open(filename, open flags, protection specifications). The default open flag is ios::out which creates the file if it does not exists. To avoid the file creation if it does not exists another flag ios::nocreate is used.

No problem with the code. Please paste the stack trace and ProgressDialog class. Rahim Rattani Software Engineer, Matrix Systems (Pvt) Ltd., Karachi - Pakistan

i dont see any problem in your code. It must be working fine and must crate the file. Check the file 1) if you are directly running the .exe, at the location of the exe file. 2) if you are executing from the vc projecy, then the file will be created at the location of workspace and project files i.e. where .dsw/.dsp exists.
