• Visual C++ Templates and LNK2005

  In a header file, I have a template with some inline methods: template <class BASE> class ServiceTmpl : public BASE { virtual string const& name() const { return name_; } ... }; Another file has an abstract base: class IInstrumentFactory { virtual void variousMethods() = 0; }; Then I have two classes: class NullInstrumentFactory : public ServiceTmpl<IInstrumentFactory>; class G3InstrumentFactory : public ServiceTmpl<IInstrumentFactory>; Now I'm getting LNK2005 errors, because apparently ServiceTmpl<IInstrumentFactory> is being instantiated twice. How can I avoid this problem ...Show All

• SQL Server How is InstanceSelection set on a report model based on a OLAP cube ?

  When autogenerating a report model from an OLAP cube, what is the criteria used by the SQL engine for deciding whether the InstanceSelection tag should be List or DropDown. As far as I can see, this decission is pure magic. E.g. <Entity ID="udm:Entity_Dimension_Person_Ulykke_Arbeidsoperasjon"> <Name>Person Ulykke Arbeidsoperasjon</Name> <InstanceSelection> List </InstanceSelection> <Entity ID="udm:Entity_Dimension_Person_Ulykke_Stilling"> <Name>Person Ulykke Stilling</Name> <InstanceSelection> Dropdown </InstanceSelection> ...Show All

• Windows Forms Custom Control With SelectedValue Property - How to determine correct "default" data type to return?

  I have a custom control that has a SelectedValue property.  It is basically a ComboBox control, if that helps.  Anyway, I have a business object that I'm binding to this control.  In some cases, the business object property that I'm binding to the control is a System.GUID, in other cases, it is a System.Int32 or System.String.  My delimea is that if the custom control's internal _selectedValue member is Nothing, because the user never selected a value or the selection was cleared, I want to return a valid data type to my custom business object. So if I'm binding to a property on my business object that is a System.GUID an ...Show All

• Visual C++ Converting byte counted strings to null-terminated strings

  Does anyone know an easy way to convert byte-counted strings to null-terminated strings I'm trying to pass a filename as an argument in a custom made worksheet function defined in an xll created in C++ 2005 express. I think the problem I'm encountering is that excel is passing a byte-counted string and the function in C++ needs a null-terminated string. So it comes down to finding an easy way to convert byte counted to null-terminated in my C++ code. Any ideas are appreciated. Thanks. One approach is to first extract the byte count, then traverve to the first element in the string. Kuphryn ...Show All

• Visual Studio how to set to open different files with different editor

  After working with sourcesafe, I am a hard believer that it sucks. I have all kinds of files checked in sourcesafe like xml, java, jsp, txt,pdfs and css. Each time I double click the file it asks me how to open a file. i.e. with which editor. (I know I can set the options using options to open/edit or check out). I have set one editor as default. But if I have to open a different types of files, I have to choose editor from radio buttons. Isn't it a pain Software should allow us to define what type of file we want to open with which editor. i.e. we should be able to define that after double clicking Source safe should open ...Show All
