Re: VC++: Derek Waters7-Mar-02 11:34 Derek Waters 7-Mar-02 11:34  Hi, Probably your best best here is to use a CFormView-derived class for your view. This acts pretty much exactly like a dialog, so you'll be able to easily move your example code over. As for Doc/View, I think the proper philosophy is that your persistent data (stuff that gets loaded and saved) goes in your document, and your view is the class that presents that data to the user. Thus, in MDI you can potentially have two views on the same document data. ------------------------ Derek Waters derek@lj-oz.com STL: returning const char* from a temp string 6-Mar-02 22:25 6-Mar-02 22:25  I have a function that has a return type of const char*, and the data inside the function is built up into a temporary std::string. I try returning "return temp.c_str();", but that doesnt seem to work the way it should. This is a simple problem, and I really dont want to allocate memory for a char* unless it is absolutely necessary, so is there a better way to handle this? Re: STL: returning const char* from a temp string Joaquín M López Muñoz6-Mar-02 22:52 Joaquín M López Muñoz 6-Mar-02 22:52  Data accessed via c_str() become sinvalid as soon as the temporary string goues out of scope. You need to maintain that string somewhere: declare it as a member of some object, or have it as a static variable in your .cpp file (this can pose problems is the string changes in every invokation.)

I wanted to avoid having memory overhead, but I guess I will stick with it. Re: STL: returning const char* from a temp string Tim Smith7-Mar-02 2:22 Tim Smith 7-Mar-02 2:22  If you want to avoid memory overhead, they why are you using std::string? Tim Smith I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk? Re: STL: returning const char* from a temp string Tomasz Sowinski7-Mar-02 2:31 Tomasz Sowinski 7-Mar-02 2:31  Hmmmm... So what's the memory overhead of std::string? Tomasz Sowinski -- http://www.shooltz.com Re: STL: returning const char* from a temp string Le centriste7-Mar-02 3:54 Le centriste 7-Mar-02 3:54  could we see the body of the function? Maybe you could try something like: std::sting myfunc() { .... return std::string(somebuforwhatever); } Just a thought Michel If I am wrong or said something stupid, I apologize in advance Re: STL: returning const char* from a temp string Tomasz Sowinski7-Mar-02 4:01 Tomasz Sowinski 7-Mar-02 4:01  Returning std::string by value will cause one or two memory allocations for the contents of buffer - two if your compiler doesn't support so-called 'return value optimization'. Please note that this is not a problem, unless 'myfunc' is time-critical function. Don't fool yourself into thinking that you need to worry after one or two nanoseconds. Try to save cycles where it really matters. If you absolutely need to reduce the overhead, you may consider changing the function header to accept std::string reference instead. Instead of returning string, you'll be using operator= at the end of the function.

See Lets say I want to write ABC vertically .. according to your solution output would be A B C but what I want is thought all the characters would be appearing in different lines but give 90 degree clockwise shift to them , as if you are reading the screen from left edge . did you get this ??

Thanks a lot Mike Re: Drawing a bitmap into a CEdit Christian Graus6-Mar-02 21:28 Christian Graus 6-Mar-02 21:28  Can't you use a richedit, and a character set that has the Omega ?

Then, in OnPaint you could draw your bitmap at the margin.
