 | I just had to look up the WM_ representation for the mouse scroll, so that I can activate my game camera zoom, more freely, rather than using the arrow keys (which was fun at first) So, I tried implementing the WM_MOUSEWHEEL into the message loop and created a switch statement …  |
| | Hi, I can't really understand what the problem is with my work computer. Below I will give a full description, and a summation at the bottom. I installed an apache server, php, mysql and mozilla, the usual. Installed Dreamweaver CS5, GIMP, SQL Server Management (accessing MSSQL databases in the system), …  |

 | Hmm, you could design a minesweeper game using [URL="http://www.dotnetspider.com/tutorials/DotNet-Tutorials.aspx"].NET[/URL] or [URL="http://www.vbtutor.net/vb2010/index.html"]Visual Basic[/URL] easily. Instant access to some of windows graphics. First you should get an [URL="http://en.wikipedia.org/wiki/Integrated_development_environment"]IDE[/URL] to work in. [URL="http://www.microsoft.com/express/Downloads/"]Here[/URL] are some IDEs for [URL="http://en.wikipedia.org/wiki/List_of_programming_languages"]programming languages[/URL]. If you're after a more advanced game build, try starting up your own [URL="http://www.directxtutorial.com"]DirectX …  |
| | I think the title says most of it. How do I, in MS Access using VBA, get information from a workbook which I can then put in as a recordset in a table? I know that excel has an easy workaround for other excel workbooks, and I've read somewhere how … |
| | Hi, I've noticed some websites don't display their content until everything's been processed, downloaded and ready for render. The result is images [B]DO NOT[/B] render after download, so there're no images popping up everywhere on the page while the page is processing its next request, but wait until it's done … |
| | hi, I'm a bit confused as to how my graphics engine actually loads a model file. Currently I'm using .x files, because that's what I was taught. But I haven't asked the most important question, how do my graphics engine actually load a model file? Using DirectX and the correspondent … |
| | Re: just help I'm not really sure what kind of hint you're looking for, but, it seems like you have a good layout of your project, as well as structure and hierarchy. Basically, all you do now is follow the same order in programming. You say a bank has several branches and each … |
| | Hm, I can imagine seekg() and seekp() or getline would get the job done. A while loop counting how many getlines you've done or just jump right in with seekg / seekp I'll give you a pointer to a good reference manual -> [URL="http://www.cplusplus.com/doc/tutorial/files/"]Input/Output usages[/URL]  |
| | If I can add something to this, [URL="http://academicearth.org/lectures/pointers-and-arrays-dynamic-memory-allocation"]here's[/URL] a lecture by David J. Malan teaching computer science at Harvard explaining pointers and dynamic memory allocation, and [URL="http://academicearth.org/lectures/pointers-to-pointers-binary-search-tree-tries-heaps"]here[/URL] he explains heaps if you want to further understand what's going on. |
| | Hm, right off the bat, I'd suggest [URL="http://www.blender.org/"]Blender[/URL], it takes a while getting used to, but it will get your job done. Best of all is it's free and have many of the functions the expensive software [URL="http://usa.autodesk.com/"]3D Studio Max[/URL] has. Then there's [URL="http://www.turbosquid.com/gmax"]GMax[/URL], also free. They all have extensive … |
| | I'm gonna take a wild guess and say that you're trying to write the entire class object (not a buffer) to a file. Apart from that, you should read up on [URL="http://www.cplusplus.com/reference/clibrary/cstdio/fwrite/"]C++ reference: fwrite[/URL], I think you misplaced the two parameters for size and count. If you want to write … |
| | And, of course, it would look something like this: [CODE=cpp]#include <iostream> #include <string> #include <conio.h> using namespace std; using std::string; #define CREATE_TABLE(name) MyClass mc(name) class MyClass { public: MyClass(string name) { cout << "class name is : " << name; } private: string name; }; int main() { string name … |
 | Hm, I had a hard time looking through your code, having all code in one file for me is really messy, however, the general idea behind switching between forms is to use the System::Windows::Forms::Form->Hide() and System::Windows::Forms::Form->Show() functions. When constructing, create both forms, hide the advanced calculator and when it's time … |
| | Hey, I was working on a ListView that was supposed to look something like the OpenFileDialog except with some differences. Up until now I've used my own images to represent each type of extension that is added to my listview (well, only two images are used, Directory and File, to … |

| | I suggest you read up on such things as this: [URL="http://www.cplusplus.com/doc/tutorial/files/"]ReadFile[/URL] Just keep doing newlines in the file, but since you known the structure of what you're getting, for example, You need 4 variables from each entry, then you loop getline and count which row you're on, take that and … |
| | In addition you have: (IOSTREAM HEADER) [URL="http://www.cplusplus.com/reference/string/getline/"]getline( istream& is, string& str )[/URL] [CODE=CPP] string mystring; getline(cin, mystring); [/CODE] (STDIO HEADER) [URL="http://www.cplusplus.com/reference/clibrary/cstdio/scanf/"]scanf( const char * format, ... )[/URL] [CODE=CPP] string mystring; scanf("%s", mystring); [/CODE] (WINDOWS INPUT) [CODE=CPP] //....

| | Hmm.. The most common way to detect the monitors size in windows is [CODE=CPP] INT32 width = GetSystemMetrics(SM_CXSCREEN); INT32 height = GetSystemMetrics(SM_CYSCREEN); MyForm->Width = 1000; MyForm->Height = 1000; if(MyForm->Width > width) MyForm->Width = width; if(MyForm->Height > Height) MyForm->Height = height; MyForm->Top = 0; MyForm->Left = 0; MyForm->StartPosition = FormStartPosition::Manual; [/CODE] |
| | I'm guessing you're running Managed C++ code and have a scrollbar control structure implemented in your form. [CODE=CPP] #include <windows.h> #include <iostream> #using <System.DLL> #using <System.Windows.Forms.DLL> #using <System.Drawing.DLL> using namespace System::Windows::Forms; using namespace System::Drawing; namespace MyForm { ref class MyForm : public Form { public: HScrollBar^ myhscrollbar; VScrollBar^ myvscrollbar; void … |
| | Hm, this seem like one of those cases where you overemphasize on the methods for <string>. What I did was remove your manual count, 'cause essentially you don't need to do the counting yourself when there is such a function to do it for you: [B]std::string::length()[/B]. Executed as such [code=cpp] … |

| | I'd suggest consistency when programming. Instead of [code=cpp] int input; cin >> input; switch(input) { case 1: //... break; } [/code] try getline with string and converting the string to an int using atoi(const char*) [code=cpp] string input; getline(cin, input); int option = atoi(input.c_str()); switch(option) { case 1: //... break; …  |
| | Hi, Yesterday when I was testing my game out, written from scratch, my DirectX debugger suddenly started spewing out this error code after a couple of runs of the program. Now, this error appears just a couple of seconds after the program goes fullscreen and starts rendering some graphics and … |
| | Hey, it seems when I try to draw textures using the Z value in the D3DXVECTOR, it doesn't affect the drawing outcome. For example, I draw a red ball, then a blue ball on top of the red ball, where the red ball has a depth value of 0.1f and … |
| | Hey, I've been working on a project for a while, and had some difficulties at the beginning with the d3dx9.h and lib files, then after some threading here I got the help I needed, or so I thought. It worked well until I decided to make a new project, using …  |

| | Alright, I'm a novice in programming DirectX but very adept at c++ in general, and I really want to learn how DirectX works! I borrowed a book from the local library called "Windows Game Programming for Dummies". Seeing as I'm dumber than a Dummie, I really didn't understand the chapter …  |
| | Hi, I remember from when I learned PHP, how easy and fun OOP was, and how to call member functions in conjuction (after eachother) on the same line, like this: [CODE=PHP] MyClass->Foo()->Bar()->Pancakes("flour etc"); [/CODE] To be able to do that, all you needed to do was make a return holding … |
| | Contrary to what the title implies, my real problem lie in returning a vector pointer, and then use it. Here's what I tried: [CODE=cpp] #include <vector> #include <string> #include <cstring> //? Needed? #define R_OK 0 #define R_ERROR 1 using namespace std; vector<string>* tester(){ vector<string> v; v.push_back("Lolzer"); vector<string> *ptr = &v; … |
| | Hey, I've been trying to understand what the hell I'm doing wrong with this code. At the beginning, I include the DDRAW.H, and the code compiles with no problem, but as soon as I try using a function from that header, I get a linker error. The function I used …  |
| | Greets, A string array in C++ can be initialized, just like everything else. With that in mind, how do you count the number of items in the array? I mean, how many rows? Let me give you an example using Char arrays (having two dimensional since it's not like string) … |
