• Ross Luengen - MSFT CWind::Invalidate Problem

  Hi, I have a dialog box that allows you to enter text, when you press 'ok' the window underneath, from which the dialog box came, is updated with the new text.  Fairly straigh forward stuff.  However when you enter into the dialog box the '&' sign followed by anything else, it removes the & sign and underlines the next character in string upon clicking 'ok'.  To my knowledge the string is not actually altered because ...Show All

• Mohe Initialize const array member

  Hi Does anyone know if / how it is possible to initialize a const array member e.g. class C_MyClass { public: const int m_MyArray[5]; C_MyClass(void);//default constructor ~C_MyClass(void);//default destructor }; C_MyClass::C_MyClass(void) : m_MyArray({1,2,3,4,5}){ } Error says it cannot specify explicit initializer for arrays.  Yes, theoretically I could use 5 const variables in this case, but no this is not actuall ...Show All

• graey VS.NET 200 Beta 2: BadImageFormatException

• rtnews0423 Repeated Relink After Build Problem

  I have a complex project with multiple regular dll's and COM dll's. The code is also being built for both the PC and Smart Devices (CE) within the same directory structure. Frequently when I edit the code and rebuild successfully, if I hit build again after it is completed the exact same set of starting dll's are relinked which triggers other files dependant on the relinked dll's to be rebuilt. I've tried to looking at the project and the pro ...Show All

• eci Invalid .ilk file should be deleted

  VS2005 sometimes gives me a message that my incremental link file (.ilk) is invalid, and then it links non-incrementally.  If this happens once, then it happens every time after that. To recover, I just delete the .ilk file myself, and the next link rebuilds a valid one. This seems like a bug to me.  If the compiler decides the .ilk file is bad, it should delete it, so that incremental linking can work again in the future. Ple ...Show All

I see that the the _vfptr member is zero. Isn't that wrong It seems to me that this is my problem, but I don't know ...Show All
