• Game Technologies: DirectX, XNA, XACT, etc. SpaceWar Memory Usage

  Hi all, I compiled the SpaceWar demo without any problem, and was able to get the keyboard to respond. My concern is on memory usage. When running the game from the Release folder (and even closed Visual C# editor), SpaceWar uses about 165Mb of memory. Now, what is it with the .Net Framework that always eats up so much memory It is just on my computer, or do others out there use that much memory that seems a bit extreme. any here have base memory requirements for a XNA peice of code with say just a single 3D object with one plane spinning ...Show All

• Visual C++ Remove a given value from a list

  Hello all: Is this solution correct void remove(Node **node, int v) { while (*node) { if ((*node)->value = v) { Node *tmp = *node; *node = (*node)->next; free(tmp); } else node = &(*node)->next; } } If this code is correct, I have the following question: why can we just free(tmp) without making the collection between the previous node of tmp with the node after tmp Thank you Are you jocking when you say it's an uncommon implementation and probably not a good idea for production Then we must be in agreement and we're both jocking. ...Show All

• .NET Development CLR profiler - StringCollection

    Hi  I have profiled one of my apps using the CLR profiler and it seems to indicate that a StringCollection was converted to an ArrayList which was in turn converted to an object array which then got converted to  strings. Why does it behave so.. Does the StringCollection use an arraylist internally Thanks Well, if performance is a concern and you don't need to add/remove strings you can use a string array. Or, if add/remove is needed and you are using .NET 2.0 then it is better to use List<string> instead of StringCollection. ...Show All

• Visual C# what is Impersonation

  can someone expain me what is Impersonation from an ASP.NET side and when it can be used. If you have any simple examples, please share. Thank you, Hi I don't believe that using code-based impersonation is even necessary... as long as you can retrieve the windows id (which you can by using impersonate = true + asp.net windows authentication) you code will impersonate the right user The example you gave is valid for applications where you need to impersonate specific admin credentials... ...Show All
