sndPlay freakin' Sound Jh323-Oct-02 4:19 Jh3 23-Oct-02 4:19  hi it's my third time posting this question in as many days! I wrote my own wave file, but when i want to play it with sndPlaySound, i only get a beep from the PC speaker. Other applications play the file fine, and other wave files are played with the sndPlaySound function in my app. WHAT'S WRONG? PLEASE!! Re: sndPlay freakin' Sound Matt Philmon23-Oct-02 4:26 Matt Philmon 23-Oct-02 4:26  Send me the file and the snippet of code that plays it. system command using MFC achandra00723-Oct-02 4:18 achandra007 23-Oct-02 4:18  Is there a system type command in MFC?

I had thought that threads allow for a process to be completed at the same time code execution is continuing past the creation of the thread. Is this a correct way to look at them (threads) and if so, is there a way to hold the program until the completion of the last created thread? --------------------------------------------- Be good!

Then call WaitForMultipleObjects on the the array in you exit handler. You can then guarantee that all your child theads have completed before your process thread. Ryan.

Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: Read File Anonymous23-Oct-02 3:23 Anonymous 23-Oct-02 3:23  This function searches a directory for a file whose name matches the specified file name. FindFirstFile examines subdirectory names as well as file names. I don't know the name of the file. Re: Read File Joaquín M López Muñoz23-Oct-02 3:24 Joaquín M López Muñoz 23-Oct-02 3:24  Look deeper into the docs The function supports wildcards, take advantage of them.

Anonymous23-Oct-02 2:53 Anonymous 23-Oct-02 2:53  It says that cout is an undecalred identifier when i #include <iostream> thanks Re: How do i use cout in Visual Studio .NET? Joaquín M López Muñoz23-Oct-02 3:05 Joaquín M López Muñoz 23-Oct-02 3:05  It is std::cout, although many samples omit the prefix for brevity. You can stick to the simpler cout including using namespace std; right after the #includes, though this is not, for a variety of reasons, a good policy to follow in general.

I need the 6.0 release (or later). Please help! Re: Visual C++ CD needed 23-Oct-02 10:50 23-Oct-02 10:50  Several Intro to Visual C++ type books offer the Introductory Version on CD with the book. I did this, thinking it was the Standard Version. http://www.microsoft.com/MSPress/books/3224.asp Re: Visual C++ CD needed puzzolino23-Oct-02 21:29 puzzolino 23-Oct-02 21:29  Thank you! I've found the same Introductory version on another book too: Learn Visual C++ N:-Dow Dynamic Link Library homer66623-Oct-02 2:16 homer666 23-Oct-02 2:16  Hi I want to create a dynamic link library in Visual C++ for use in Visual Basic. From VB i pass a String to the dll, so far so good, but now i want to return another String to the VB-program. My problem is now the memory access error, that occurs in the running VB programm. What types in the c++dll can i return to VB, that expect a String?? thanx for your replies Re: Dynamic Link Library Joaquín M López Muñoz23-Oct-02 2:23 Joaquín M López Muñoz 23-Oct-02 2:23  A BSTR, I think. CComBSTR could be useful to do this. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
