Just becareful with memory leak and you are rolling.
As far as I know, list, map also make copy of inserted element.

hi
i wanna know how to turn on/off the lights with a C code.
would u tell me what hardawre i do need to do this and also tell me how to write the code?
thx

i don know to search for what.
i don know anything about these subjects.
would u tell me an introduction about it and what to search for and i will look for them myseelf.
thx so much

i'd like to help you more, but still i don't know what you're looking with more precision, i can't...
are you yust looking for programming help, or you are asked to design the electrical/electronic part of that system ?
do you use a PIC or so to code this in C ? (and is it necessarily in C ?)
you'll have to provide more infos if you want some consequent help, otherwise the best you'll get will be people asking for what you want, the worst being insults...
any help so ?

hi toxcct
u know i am a complete idiot in these subjects.
i don know wether i can program such a thing with C.
but would u say if i want to do such a thing, how should i and what should i do? and what hardwares do i need.
or i need an elect kit?

you don't really answer my questions...
please do it if you want me to help you more efficiently.
moreover, i have some more for you :
what lights do you want to act on ? small LEDs, or big ones abstrated behind an automaton ?
is there even something started designed on this, or you start the whole job ?
do you do this for you or were you asked to ?

no i just want to do it for myself
i mean these simple light bulbs not a LED.

well, your thread contains an hardware question (which should have been asked into the Hardware forum[^]).
for what you look for programming, you should first learn at PICs and PALs integrated circuits, because your code cill depend a bit on which you code for... moreover, it will also depend on how you consider turn the light on/off (distant interruptor, radio connection, special condition from within the embedded code, etc...).
sorry but i can't help you more until you don't tell me how is designed (or at least, how you imagined as designed) you project (HW + SW + linkage b/w them)

Hi I have not really tried extensively and I only saw one instance so far but have forgotten what happened...
What may happen if a multi-threaded executable calls a single-threaded DLL? This is not thread safe. What can one do to make it threadsafe--if the 3rd party vender refuses to provide a multi-threaded version of the dll unless you increase the money?..

Hi, I've got a ListBox and I want to know the max number of characters, that can be added in a single line. I need this because there is an info that exceed in characters the width of the ListBox. What I'm thinking is get the max number of characters and cut the info in several lines.
Any idea?
Tnx
|
|
|
|
|
|
?? And the max characters that can be written in a single line?
|
|
|
|
|
ok, maybe I'm stupid, but it seems to me that after I called one constructor and the program returns it automatically calls another overloaded constructor.... why can this happen? I will check the program again tomorrow and try to describe the problem a bit closer and maybe provide some code, but just in case anyone has an idea I post this tonight.... drives me crazy right now... thanks!

I am on a project that reads in assembler language from a file and then prints if out. here is an example.
input:
ADD 4,2,1
TEST
JMP 3
BR 14
ADD 3,7,9
the output should look like this:
Op code: ADD
Params: 4
Params: 2
Params: 1
Opcode: TEST
No Params.
Opcode: JMP
Params: 3
ect......
Here is what my code looks like:
int main()
{
string theLine;
string op;
string p;
ifstream infile;
infile.open("assembler.txt");
int line=0;
while(getline(infile,theLine))
{
cout<

You will have to parse the string that has the commas. Consider the line of code in your example:
cout << "Paramers:" << p << endl;
As it is now, p will point to the string "4,2,1" for example. You should test p at this point for commas, perhaps in a loop, parse and tokenize each number between commas, and print the result (each parameter).

Hello again,
I need to 'quickly' learn how to override some methods of the toolbar class. I'm pretty close to totally ingnorant of how I go about this so all help would be gratefully received. I know how to inherit from a base class but I don't know how to override methods and how to use my new class with the overridden methods.
I specifically looking at how to override the Enabled property so that instead of getting rid of the image it just shows a new image and how to override the button click method so that the button is no longer 'clickable' when enabled equals false.
If anyone could point me to some source code of how the base class goes about things I could probably work it out for myself - eventually  .

I'm looking for someone who can create a print driver for Windows that converts documents to PDF and is free of all licensing. After converting to PDF, I would like the file to be POSTed to a web server.
PM me if interested, and I will send you a document that includes all specs and required functionality.
Thanks

Are you offering to pay someone, or are you hoping for a freebie ? I'd be looking in sourceforge as a first step, and downloading the PDF file format as a second ( it's pretty straightforward )

I am offering to pay someone. Send me an email if you think you can handle something like this.

You would be silly to pay someone to do this, when there are commerical products you can buy that do it. Buying a library is always cheaper than paying someone to write a new one.

hi, all. I got 4 warnings when build the application like this
"warning C4520: 'CRptLog' : multiple default constructors specified", when I tried to debug the code, got some assertion failed, because for somereason, they only want certain value for some calltype.....then I found the application has memory leak:
Warning: skipping non-radio button in group.
The thread 0x874 has exited with code 0 (0x0).
Detected memory leaks!
Dumping objects ->
{1439} normal block at 0x0146D6B8, 2804 bytes long.
Data: < v w > 0A 00 00 00 08 F9 76 00 E0 77 17 00 00 00 00 00
{1438} normal block at 0x01450FA8, 18 bytes long.
Data: <data\download.db> 44 61 74 61 5C 44 6F 77 6E 6C 6F 61 64 2E 64 62
could anyone tell me is it because of the warning C4520 or the assertion failed causing memory leak?
the release works just fine.....appreciate any info.

Probably you have a default constructor ( CRptLog() ) and one that takes arguments and has default values ( i.e. CRptLog(int itemCount = 0) ). Now, if you call a constructor and don't specify an argument, which one will be called ? I don't know either.
valerie99 wrote:

You should know more than that - you should go into debug mode from here to see where it happened, and find out what it was.
valerie99 wrote:

This means you have a dialog box where the radio buttons were not all put on at once, but it's still trying to group them together. No big deal.

Neither, probably. The memory leak means you leaked memory, probably strings ? Do you use char * in your code ( you shouldn't, but still.... ). You should chase down the assertion, it's there to help you, and it can't if you don't pursue it. It may have something to do with your memory leak, but there's no more than a 50/50 chance of that.
