Two alternatives:
(1) Change the Character Set option of your project (currently is Use Unicode Character Set). You can do this selecting Project->Properties menu item, then Configuration Properties->General node and finally the Character Set list item.
(2) Change you variable type. For instance
char msg[]="foo";
should become
TCHAR msg[]=_T("foo");

for converting const strings to wide char you can just add L.
e.g. L"SomeText".

Hi everybody..
I am doing project on gsm modem.i am reading msg from sim.that read message i want to store into database.for that i have split that sentence so please tell me how to do that.. i am doing like this..
char str[1000];
strcpy(str,m_sResults);
MessageBox(str);
char delims[] = ",";
char* result;
result = strtok( str, delims );
while(result != NULL )
{
MessageBox(result);
result = strtok( NULL, delims );
}
but doing like this is impossible to store the values.so i want to store in different variables.please help me out.
in m_sResults the sentence is
AT+CMGR=1
+CMGR: "REC READ","919860716641","P apu.soni","08/05/22,19:05:34+34",145,4,0,0,"919890081132",145,106
Call me when you reach to your pg... I on the way to room..
OK
please help me.
thanks in advance,
savitri

Don't use strtok since internally it uses a static buffer which will cause problem with calls from multiple threads or simultaneous calls on different strings.
Instead use strtok_s/_tcstok_s, a demo -> http://www.tenouk.com/cpluscodesnippet/viewtopic.php?p=474[^]
Use vector<string> to store strings that are tokenized by this function.

don't use the token related functions for delimited file streams as they are dumb when faced with somthing like...
One,Two,Three,,,Six,Seven,...
It treats the three consecutive commas as one which could lead to unexpected results if those delimiters should be treated as "nothing" values for their respective indexes.

You can also use stringstream to parse strings. Since I couldn't find a reference, i wrote a quick sample. Check it below.
#include "string"
#include "vector"
#include "sstream"
...
string sResult(_T("Hello,can,you,split,me?"));
istringstream ResultParser( sResult );
string sToken;
vector<string> vResults;
while ( getline( ResultParser, sToken, ',' ))
{
vResults.push_back( sToken );
}</string>
Regards,
Jijo.

Hi. I have a little question:
I need to convert a memory direction printed on a CString variable, to a LPVOID variable. Example:
CString auxstr;
auxstr.Format(_T("%p"),p_Stereo);
LPVOID pointer = (LPVOID) ??????? variter->second.value;
I don't know how to convert this string to be able to cast it as a LPVOID. Anyone knows how? Thanks.

Well as the pointer adresses are 0xADRESS, should you not convert from CString into Hex and then make the assignment?

Yes, I suppose I should. But I can`t find this conversion (from cstring to hex). Is this from the atoi, atof...family? Can't find this.
Thank you so much.

Use strtol function. Specify base as 16.
e.g.
const long Val = strtol( "0xffff", NULL, 16 );

This works perfectly....but as you can see, now i have many doubts for it to be the best solution. The overall plan, not yours.
Thank you..

The question, why do you store the address in a CString object in the first place ? Can't you simply store it directly in your LPVOID pointer ? It seems a bit crazy to use a CString in between.
|
|
|
|
|
No i can't. It's the way my program sends information between program blocks. In most cases they just send numbers or strings, but now i need to send an object.
|
|
|
|
|
Yeah, but why do you store that address in a CString instead of simply sending the address ? You can only exchange CString objects ?

Basically your 'programs blocks' communicate via e-mail. This is crazy programming, isn't it?

I don't know if that is the case, but client/boss specifications sometimes (more than desirable) are "crazy"

I agree, indeed they are often crazy. Anyway communication details between program blocks should not be affected by client/boss specification, since it is matter of technical implementation.

Maybe...i might be some stupid...maybe i change it all....
Ok. I've been thinking (it's not my best quality ). I' going to define two kind of communications. Messages and pointers. SCALABILITY! I'm a genious!!! Thank you all.

I think you need to view that at a higher level. Why in the first case do you need such "communication" mechanism ? Which 'parts' of your software needs to communicate and why ?
Ask yourself the correct question, this will already give some clues for a potential solution.
|
|
|
|

I agree. I'm not programming it as you might think...
I'm developing a part of an artifitial vision software. I want to command all the staff throught a flow chart editor (block diagrams). I want it all flexible and i need a mechanism to communicate the blocks.
Now, i've found a solution, but it's time to analize if it's the best solution.
Thanks for all your opinions. They all have helped me!

Maybe numbers too. Good luck!
