Dear Sir
I wounder to know the mfc that used to open files (or to run exe files) within the VC++ project.
Thanks for Assistant

Hi all,
I am working with ADSP BF533 who's software is very much similar to VC++.
Let me explain the out line of my code and then tell my problem
----------------------------------------------------------
void main(void)
{
all the innitializations.....all other functions are called here
while(1)
{
for (i =0;i<100;i++)
-----
-----
if( a cetrain condition is met)
{
fp = freopen("", "a+", stdout);
printf("\n\r================\n\r");
printf("%f\n\r",azm);
fclose( fp);
}
}
}
-----------------------------------------------------------------------------------------------------------------------
so I don't think I can open and close the file outside the loop(as all my code is there inside "while(1)" loop.(do let me know if there is a possibility to open and close a file only once even in this situation,If i can do this then my problem is solved)
also I have noticed that I am able to print as many times as I want before closing the file once.
but after I open and close the file for the 1st time,i am able to open the file for the second time but I am not able to close the file for the second time....
here i am trying to send the data out from the processor's memory back to the "terminal screen"....through the UART
so tried to debug the code then i realised that for some reason the UART_LSR registers is not being reset to 0x0060 as it should be done after each transfer is complete.....this situation araises only when i try to close the file for the second time (obvisouly after i open the file for the 2nd time)...
SO NEED HELP FROM THE EXPERTEIS ...
thanking you all in advance and hope to hear from u all soon
with best regards,
shwetha

Hi i have one CString which has text in it, i wish to scan thsi text and replace all the "\" with another charature.
However every time i try to search the string looking for the "\" using strchr etc all i get is an error message saying
error C2001: newline in constant
any help on how to slove this?
|
|
|
|
|
it is "\"", not "\"
use strchr(p, '\"') is better
or CString.Replace() function
do you mean "\\" or '\\'?
|
|
|
|
|
i'vew tried both Replace() and strchr and they dont find the \ in the string, i tried str.Replace('\"', 'A') and it did nothing, if i change the '/"' to another letter in the string it replaces them perfectly.
any idea whats up?
thanks

the \ is '\\' in code.

Because "\" is an escape character prefix you have to write "\\" if you mean the "\".
You can also escape other characters with the single \, e.g. \n \r \"

i have a bat file which runs when system starts (i add it in register of "...\Microsoft\...\Run").
it runs properly.
my Qrestion:
I hope dos window launched by the bat file is invisible (hidden or similar), so users will not see the dos window when system starts.
how to do that?
thanks

mkae a shortcut to the batch file. go the property of the short cut and tell it to run minimised. then tell windows to run that shortcut in startup. that should slove your problem

I need a map where I can find the value to a key and also a key to a value. Since I can't find any article on Codeproject regarding this issue, I ask this question here: Is there a simple solution to this? My idea was to simply use two CMaps: CMap<KEY, KEY&, VALUE, VALUE&> and CMap<VALUE, VALUE&, KEY, KEY&>. Is there a simpler approach? Thanks for any help.

Isn't there a simple MFC class somewhere out there as extension to CMap, because I don't want to use the huge boost library?
Konrad

I've not come across one and yes I too am put of by the huge Boost library. I vaguely recall coming across a simpler solution somewhere but I can't think where. Maybe on CodeGuru?

Nearly all of Boost is in headers and it does not add lots of code to your app. The fact that it is large is irrelevant IMO. MFC and STL are also large.
I would definitely recommend using STL and Boost wherever possible instead of the MFC Containers (which I used to use heavilly).
Boost.MultiIndex will do what you want and it looks quite elegant. Of course you can use two CMap's or two STL map's but why would you want to.
Make the move to STL and Boost and you'll never regret it.;)

Well, I've only comparatively recently moved from dial-up to broadband. With dial-up it just wasn't worth it. Now I've got broadband it's more psychological.

Recently I've been more focused on .NET,so I've not had much incentive to look into Boost. When I do get to do C++ it's invariably maintenance work on code that's barely heard of STL, yet alone Boost! (For that nmatter it's often barely heard of MFC's data structures!) I just don't think it would go down too well if I downloaded Boost just to do maintenance work.
However, for new work or new extensions to MFC apps. I tend to go for STL containers nowadays. Still, I do intend to give Boost a try at some point.

You probably can insert only the relevant classes into your project.
Boost is all source code.
I am doing so with the smart-pointer classes from boost.
You will want to stay well clear of the MFC-containers, as the STL containers are better in all respects, and are well documented and portable.

If you're working on an MFC app. it's generally going to be non-portable anyway, so why is it important to use portable STL? I agree that the STL containers are better and I use them for that reason, not because they're portable.

If you don't expect the number of keys to be very large, you could just write a simple function to do the latter (i.e. return the collection of keys that map to the value).

Did you checked one of the best available source code here[^]

Thank you very much. I also found that article, after I posted my request. I already programmed my own CMap extension class, because I use MFC in my project (and therefore don't use STL, because I don't want to mix them). I will write an article about my extension class for codeproject when I have some free time.

Why not? What's the problem?
