Re: How can I make my app to use less memory Mike Nordell2-Jul-02 8:10 Mike Nordell 2-Jul-02 8:10  John Simmons / outlaw programmer wrote: Last item of note - I'm not sure if there's a limit on the size of the stack in a 32-bit program. There is no limit here, except when the virtual memory for stack bottom reaches something else (such as a heap). Then it will surely go down in flames. It can AFAIK be changed by e.g. linker flags (changing the PE flags), but to my knowledge it has never been used in production applications.

If you're using heap memory your app will have larger memory footprint. There are a number of ways you can reduce the memory size of your executable, but they always boils down to: know what you're doing and what your compiler and runtime library is doing for you. Do Windows use some kind of garbage collection? Absolutely not. That's your responsibility. Then my app has been running for a while the memory usage is lesser. Why? There could be a number of reasons. One of them could be that you just looked at what was currently committed to RAM and not the total Working Set. When you minimize any app its working set is "trimmed" (SetProcessWorkingSetsize(-1, -1); IIRC). How can I read from Serial Port? 2-Jul-02 1:21 2-Jul-02 1:21  I need to read the serial port, but I cannot read it. I had configure the DCB structure with baud rate of 9600, NOPARITY, 1 Stop bit, and 8 bits of ByteSize. I can write to the port, I'm using the function WriteFile, and it works fine. But when I attempt to read the serial port, it fails. The code is: ReadFile(hDevComm, chInput, 10, &dwBytesRead, NULL) and the return value is OK and dwBytesRead 0 thanks in advance!

This should be a easy task for most of you, and it sounds easy, but i can't find in my SDI with MFC aplication where to use WS_MAXIMIZE, but i'm not sure if this is the appropriate procedure because WS_MAXIMIZE is related to a window not an aplication, can you help me?

Thanks Re: Maximizing Aplication Nish Nishant2-Jul-02 2:05 Nish Nishant 2-Jul-02 2:05  I created a new SDI app using VC++ 6 and added the code I had shown. And the app started maximized and without a flicker as well. If it returns to a normal state for you, you must have over ridden some other functions as well. Do this :- (1) Create a fresh SDI app (2) Use the code I had shown in the first post Nish Author of the romantic comedy Summer Love and Some more Cricket [New Win] Review by Shog9 Click here for review[NW] Re: Maximizing Aplication RuiSantiago2-Jul-02 2:17 RuiSantiago 2-Jul-02 2:17  Well, i did it, and it worked, i don't know why it doesn't in my application, what do you think is most probable to be happening? What else can i look for to find where am i iver ridden other functions, i keep on debbuging but i can't find the reasin for the Frame to come back to its 'normal' state! Thank you Re: Maximizing Aplication RuiSantiago2-Jul-02 2:22 RuiSantiago 2-Jul-02 2:22  Well, i guess i found the reason, when i change windows i use: pNewActiveView->Create(NULL, NULL, 0L, CFrameWnd::rectDefault, this, ViewID, &context); pNewActiveView->OnInitialUpdate(); maybe its because of the CFrameWnd::rectDefault that it over rides that argument, what do you think? How can i change it to maximized, i look at its member function and variables but nothing seemed to fit with my intents! Thanks Re: Maximizing Aplication RuiSantiago2-Jul-02 3:41 RuiSantiago 2-Jul-02 3:41  Well, it was not what i expected I'll trying to find witch function i over ride, if there is someone who has a ideia i would appreciate very much an advise. Re: Maximizing Aplication RuiSantiago2-Jul-02 4:34 RuiSantiago 2-Jul-02 4:34  Hoorah, viva!!! I found it!!

How can I read line to line with CFile Class? 1-Jul-02 21:53 1-Jul-02 21:53  My problem is that I can not compare the character 13 which is carriage return and the character 10 newLine. I attemp to do f.e char buffer[10]; if ((buffer[ct]==\13)||(buffer[ct]==\10)) too I have attempt: if ((buffer[ct]==0x0D)||(buffer[ct]==0x0A)) also if ((buffer[ct]==char(13))||(buffer[ct]==char(10)) but any other way it works fine. I don´t know why it is the cause. The program entry not for this way. thanks in advance. Re: How can I read line to line with CFile Class? Nish Nishant1-Jul-02 22:41 Nish Nishant 1-Jul-02 22:41  If you want to read line by line, use CStdioFile instead of CFile and call CStdioFile::ReadString which reads a line of text Nish Author of the romantic comedy Summer Love and Some more Cricket [New Win] Review by Shog9 Click here for review[NW]
