How to write a code to increment by 4 needhelp5725-Oct-02 10:43 needhelp57 25-Oct-02 10:43  I am writing a program that provides the cost depending on weight. If the item weighs less than 16 ounces, the cost is $3.00. If more than 16 ounces the cost increases by .50 for each additinal 4 ounces. Here is what I have so far. It give me the 3 (not showing current format of $3.00) for weights <=16. But >16 shows a negative number. Can some edit my code so it'll work? URGENT #include <iostream.h> #include <stdlib.h> #include<stdio.h> int main() { int wgt; int x=0; double cost; int n = 4; double i = 0.50; double y; cout <<"Enter the weight" <<endl; cin="">> wgt; if (wgt <16) cost = 3.00; cout <<"The cost is" <<cost <<endl; ="" { ="" if ="" (wgt="">16) wgt = wgt +x; x= n++; y= i++; cost = cost +y; cout <<"Do you want to calculate the delivery"; cout <<" cost for another package?" < Re: How to write a code to increment by 4 Chris Losinger25-Oct-02 10:58 Chris Losinger 25-Oct-02 10:58  sounds like homework, to me so, here's a hint: if weight > 16, find out how much greater, then multiply the difference by $.50. -c "[it was..] one of those evenings when you feel that not only will there definitely be a revolution, but that the Association of Manufacturers will foot the bill." -- Umberto Eco, Foucault's Pendulum Smaller Animals Software Re: How to write a code to increment by 4 needhelp5728-Oct-02 7:29 needhelp57 28-Oct-02 7:29  As I see it this will only work if the cost is $.50 per amount >16. I need to figure out that amount at $.50 per increments of 4. (4 for .50, 8 for 1.00, etc.) How can I do this?

Auto-completion after . or -> doesn't work User 665825-Oct-02 10:34 User 6658 25-Oct-02 10:34  Hi In my current project the auto-completion suddenly does not work anymore. Usually if you type e.g. CString foo<br /> foo. a list of all available functions should appear, but that's not the case anymore. I already deleted the class-wizard file, but that didn't help Any suggestions? thanks in advance modified 12-Sep-18 21:01pm.

Inserting your own warnings into code nde_plume25-Oct-02 9:35 nde_plume 25-Oct-02 9:35  I want to insert my own warnings into code, to leave a fixed record of things I have delayed doing. For example, I have a function that converts a block of data into ASCII text, for storage. However, the first quick and nasty implementation does not get very good compression performance. So I want to insert a line in the function saying something like: #pragma message(__FILE__ " (" __LINE__ "): warning C1234: " \ "Need to improve the compression here.") However I cann't get it to work right (__LINE__ is a number, and #__LINE__ doesn't seem to work in this context.) I seem to remember something here about this, but I couldn't find it. Any suggestions would be most helpful.

Anyways, for future readers interested in how to do it, here is what I now use: #define STRINGIZE(x) #x #define EVAL_STRINGIZE(x) STRINGIZE(x) #define WARN(warning) message(__FILE__ "("EVAL_STRINGIZE(__LINE__)"): warning C1000: " warning) Put these macros in a general project header included everywhere (I guess you could even put them in stdafx.h if you are so inclined, personally, all my projects have a file called Project.h that is the first included in every header.) Then whenever you want to issue a warning during compile time just use this: #pragma WARN("Using bubble sort here, a better algorithm is required") which will appear on your compiler output (and task list if using VC .Net), which you can F4 through. When you fix the error, just remove the pragma.

I'm using the following code: BOOL CToolTabsDlg::PreCreateWindow(CREATESTRUCT& cs) { cs.style &= WS_MAXIMIZE; return CDialog::PreCreateWindow(cs); } Does this not work on dialogs or am I doing something completely wrong? Something I just tried was putting a breakpoint on the cs.style statement just to see if the value changed and my program didn't even break. Obviously I'm doing something wrong but I'm not sure what it is.

I would like to know is it possible and how to internally (program) resize a dialog box. For example: --------------------- | | |edit box | |button | | | --------------------- Given a dialog box with that looks like the one above, I would like to programmably resize it. -------------------- | | |edit box | |button | | | | | | | | | -------------------- In other words, I would like to expand and contracts the dialog frame.

Thanks. Kuphryn speed: loading bitmap Anonymous25-Oct-02 8:21 Anonymous 25-Oct-02 8:21  I've tried to load a bitmap sequence using VB.NET and .NET framework. Here's the spec: (a) class Bitmap("filepath") (b) 7kB per bitmap (or frame) (c) 588 bitmaps in sequence - Therefore, preloading the entire sequence is impossible (will consume over 250MB RAM!!) (d) 15 frames per second The basic process is as follows: (a) preload a certain number of bitmap (b1) start a thread to start rendering pre-loaded bitmap to screen (b2) at the same time, start another thread to continue loading the rest of the sequence into memory (bitmaps) However, even at a low 15 frames per second, the buffer is emptied too fast and frames loading (b2) is not able to keep in pace with frames rendering (b1)... But on the other hand, pre-load the entire sequence is just impossible!!? I wonder how they do this in Windows Media Player or Adobe Premier. Premier was able to render my bitmap sequence without any jitter on the same machine!? So, can I conclude that "class Bitmap" constructor from .NET framework is not very efficient in loading bitmap? Should I try CBitmap and build a MFC app to test it out? Or should I build a DirectDraw SDI...? What can I do? I was considering using Quicktime player (downloaded Quicktime SDK and got the sample working). But this option requires that we go thru the proper licencing process... so screw that... Thanx! Re: speed: loading bitmap devvvy25-Oct-02 8:23 devvvy 25-Oct-02 8:23  forgot my email... my email is: norman_lm_fung@hotmail.com thanks! norm Re: speed: loading bitmap Paul M Watt25-Oct-02 8:44 Paul M Watt 25-Oct-02 8:44  You can preload the images if you would like, even though you have 250 MB loaded into the heap, it will simply be paged, so you will not really be using 250 MB of ram. When the system needs the memory page that contains the next set of images, it will swap the page into memory. The media players use a compressed form of the images and therefore preload all of the data (images) into memory, then render the frame when it is time to be displayed or at least pre-render it in a cache waiting to be displayed. What I would suggest for you, if this is a possibility, is to convert your images to an AVI then use one of the media players to display the AVI.

Re: speed: loading bitmap Anonymous25-Oct-02 12:55 Anonymous 25-Oct-02 12:55  any idea where to get free avi player control? free for commercial distribution? i am aware of CAnimateCtrl (VC6) and MCIWnd class (prolly also for VC6 only). Will u recommend....? And if I want to go with VB.NET, then is there any free control available? Re: speed: loading bitmap Paul M Watt25-Oct-02 21:19 Paul M Watt 25-Oct-02 21:19  You could just use the standard windows animation control. There are only about 6-10 functions that are required to use it. That is probably the control that is wrapped in the CAnimateCtrl of MFC. Otherwise if you need advanced features you could look into the media player or even DirectShow.
