• Morg Inherited Project settings

  I converted VC6 project to VS 2005 and converted it as unicode and static MFC dll. I was not able to use /MT & /MTd since _AFXDLL is defined. I did #undef _AFXDLL in stdafx and I am able to build the project.   Later I found out that _AFXDLL is in proprocessor and in Inherited settings, there was no option just to remove that def. So I removed inherited properties using the check box, but is removing the existing setting in prepro ...Show All

• UNet Live Source Browsing does not work in comments

  Hi, I am writing this comment in response to the article "Live Source Browsing in Visual C++" by Boris Jabes and Ameya Limaye, which explains the advantages of the new browser mechanism in VC++ 2005. In my experience, however, the browser feature was practically broken in VC++ 2005. Now F12 button (as well as other browser related commands) do not work neither in comments nor in blocks disabled by #ifdef nor in Build Output window. I n ...Show All

• Sourav Parida COM suggestion

  So I have my nice object hierarchy , derived from a common base object , say TObject. The code is pure c++ and should remain in that way for compatibility. I mean, no WINDOWS or MFC/ATL types. Now, I need to write a COM wrapper to access that framework from VB. I will use Attributes with ATL and link the DLL of the framework. Anyway , since I'm new to COM programming I ask you some hints. For what I've understood until now, each class will requi ...Show All

• cis_student Frequent IDE freezing

  When working on a large C++ project the IDE frequently (approx once every half hour) freezes. It's been doing it since I started working on it when it was released, but I was never able to find a specific cause that triggers the problem but it seems to be related to browse information and/or intellisense. It happens more frequently when editing .h files that are #included by a large number of source files. The IDE freezes, the cpu stay ...Show All

• dover1 Button

  How would you make a text box say something from clicking on a button I've tried text_box1 = (((text_box2 * 9)/5)+32); But it didn't work. Why Sorry but give us more infos. What I can see is a calculation and variables that seams to be text boxes in a form. If you want to set the contents of a text box use the text property (text_box_1.text). If you want to calculate Celsius to Fahrenheit, you have to read the contents of text_box2 agai ...Show All

• Canes86 Derived Hashtable Problems

  Hi - I have created a class that derives from Hashtable whose items are arraylists, creating a multimap of sorts for which I can iterate through all the items of the same key. I have overwritten the set_Item property method so that adding an item always places it in the arraylist for the given key. I am having trouble with the get_Item method though. If I don't define the get_Item method than I get a compiler error when I try to use it, e ...Show All

  Hi, In the modification of my genetic algorithm that I have been working on, I need to specify an evaluation function. My evaluation function so far is shown below but this is a very simplistic version and I need to develop it.
