    Grant problems with Roles

    ok, i found out why. From Oracle documentation on CREATE VIEW: Prerequisites To create a view in your own schema, you must have the CREATE VIEW system privilege. To create a view in another user's schema, you must have the CREATE ANY VIEW system privilege. To create a subview, you must have...

    Grant problems with Roles

    Hi, This doesn't make sense to me. Scratch does not need the right to select from admin01 because, if you look at the code, it is scratch who is trying to create the view in admin01 (and there are no tables in admin01 to select from). Additionally scratch already has the SELECT ANY TABLE priv...

    Default Value not firing when using a View/Trigger

    Hi, I got a bit of a problem with this one. Below is a small sample of the replicated problem (because the real tables have many more columns). CREATE TABLE abc ( IDENT VARCHAR2(100) NOT NULL PRIMARY KEY, CREATION DATE DEFAULT SYSDATE NOT NULL ); / CREATE OR REPLACE VIEW abc_v (IDENT...

    Adding a foreign key constraint to USER_TABLES

    Hi, ALTER TABLE TABLE1 ADD ( CONSTRAINT FK_TABLENAME FOREIGN KEY (TABLENAME) REFERENCES USER_TABLES(TABLE_NAME) ); This gives me insufficient privileges - but I thought User_tables was a user accessible table. Is it possible to do this ? Rich. Programmers are tools for converting...

    COM Exe server in C#'

    I discovered there is a way of using a C# class library (a .net dll) through COM interop and have successfully written client applications in c++. However is there a way to create an exe class library ? Thanks in advance. Rich. Programmers are tools for converting caffeine into code

    Shared Singleton across DLLs

    Hi, You can use #pragma data_seg in your DLL to share the same instance of the singleton. Note that this will also share the same data across all applications that use the Dll. You can google on #pragma data_seg. Hope this helps. Rich. Programmers are tools for converting caffeine into code

    STL: remove_copy_if in a Class

    Hi, I was happy that I found a STL way to copy elements using a functional condition : bool FileNotExists(string Filename) { return (FileExists(Filename.c_str()) == FALSE); } int main() { vector<string> filenames; filenames.push_back( string("C:\\File1.txt") ); filenames.push_back(...

    Annoying Delay in Explorer

    Hi, Thanks for your replies ! Indexing Service was turned off, so I have turned it back on - I dont know if this will affect the performance. I have also run chkdsk /f which seems to have fixed the problem (accessing the same directories is near instant or < 1 sec at least). I will monitor...

    Annoying Delay in Explorer

    Hi, I am getting a problem when using Windows Explorer : When I browse to a directory there is a delay (approx 30 seconds) before the contents of the directory show. During this time the explorer window goes into Not responding. It happens quite often but seems to frequent on folders that I...

    Confused == operator

    Hi, Ok I understand that the two pointers are being compared. What I dont understand is why .... bool result_2 = (MyStr("hello") == MyStr("hello")); Why does MyStr("hello") call into operator const char*() and not operator == (MyStr& ) Regards, Rich

    Confused == operator

    Pop quiz: class MyStr { public: MyStr(const char* newValue):s(newValue) { } operator const char*() { return s.c_str(); } bool operator == (MyStr& rhs) { return rhs.s == s; } private: std::string s; }; int APIENTRY _tWinMain(HINSTANCE hInstance, HINSTANCE...

    Multiple Dialogs, but closing one closes them all

    Hi, My app may open several instances of the same form. However closing the first form ( this is the one with the [STAThread], Application.Run etc ) then all instances of that form close at the same time. Is there a way round this ? Thanks Rich.

    ExistsInList template function

    Hi, The function was declared in stdafx.h, but the body was defined in stdafx.cpp. Moving the body to the .h fixed the problem. Thanks! Rich. Programmers are tools for converting caffeine into code
