call stack?
I found that my program was blocked here:
->LPTSTR pstrBack = _tcsrchr(pstrRoot, '\\');
LPTSTR pstrFront = _tcsrchr(pstrRoot, '/');
in BOOL CFileFind::FindFile(LPCTSTR pstrName /* = NULL */,
DWORD dwUnused /* = 0 */)
pstrRoot is correct

The '^' shows where you name stops. Normal convention is to round up if the digit after is 5 or above, thus I feel your name should be:
3.141592654
Now that’s taking being pedantic to whole new levels.

I do not think the debugger or call stack or whatever will get you out of this trouble. Indeed, nothing seems wrong with this code. It has noting to do with your build settings, normally erros with that result in huge numers of error messages.
I think this has to do with corrupted memory. It may be caused by any part of your application. What I would do in this circumstances is to isolate parts of the application by switching off code (cemment out). Then try to find out when te problem disappears. Italso ma be useful to check carfully for possibly corrupted memory. Did you intialize all pointers? Did you maybe release meory (using delete or free), but try to accessthis memory from other places? Is it possible that you exceed any array bounds? It may take a lot of time to debug.
I wish you good luck in this bug hunting. It happened to me two or three times in my career, but I always found a reason for tis behaviour.

Hi all,
This is a basic C programming question.
I need to save group of data in to a file with the datas separated by commas.
But, if the datas have commas within themselves, I need to strip that comma and save the data as one single word without commas. But each data item needs to be separated by commas.
Can anyone tell me how to escape or strip the comma if it is within the datafield.
eg., 1, Steve,Dave, 25yrs, California
I want to strip or ignore the comma that is between Steve and Dave and store the data as
1, SteveDave, 25yrs, California
I know this is a basic question. But i need help in this guys.
Many thanks in advance.

Easy, just read it character by character in a simple for loop, if it's comma, ignore it.

how to ignore it?
how can i print the data without comma?

Wait I re-read your question, I misunderstood. I got your question this time.

You can see if the next character is space, if not, then it's in the datafield.

I dont understand. sorry.
I have a group of data fields. each data field is separated by comma but the data itself shouldnt have a comma in it. ie., for eg., St,eve, David, Ross
I want to print just Steve, David, Ross by ignoring only that comma that is between 't' and 'e' . i need the other commas to separate the datafields.
how do i do it?
if u can showe some code snippet, thats great.

Okay, suppose you have a txt file called data.txt, where the content: St,eve, David
The following code will print Steve David
modify the code a bit yourself to add comma in the end result. Hope that helps.

#include < stdio.h ><br />
<br />
int main(int argc, char *argv[])<br />
{<br />
FILE *fp = NULL;<br />
char buffer[20] = { 0 };<br />
char ch = 0;<br />
int i = 0;<br />
<br />
fp = fopen("data.txt", "r");<br />
<br />
for (i = 0; (i < 20) && ((ch = getc(fp)) != EOF) && (ch != '\n'); i++)<br />
{<br />
if (ch != ',')<br />
buffer[i] = (char) ch;<br />
else<br />
i--;<br />
}<br />
<br />
buffer[i] = '\0';<br />
printf( "%s\n", buffer);<br />
<br />
fclose(fp);<br />
<br />
return 0;<br />
<br />
}<br />

thanks.
how do i do it if the contents are stored in an array of counted byte strings instead of a file.
eg., row[0]=Steve
row[1] =david
row[3] = ross

The requirement was to save to a file, not read from it.

Hope I understood your question
if you want to delete comma of you can use CString::Find for get commas and then remove their of your string with CString::Delete.

I think he is asking how to parse a file that contains comma and want to ignore them when parsing.

This is a C question, not C++/MFC.

If the string to be parsed is "1, Steve,Dave, 25yrs, California", there's no way to reliably differentiate between the various commas. Depending on the placement of a space is unreliable.
Now, if you have control over how the aforementioned string is put together, then a solution is very easy.

I created a edit box and a "apply" button. when i clicked button, I want it can retrieve the value which i typed in the edit box.following is my code, but why it doesnt work?
void CIPConfig::OnBnClickedButton2() // enable
{
UpdateData(FALSE);
int level;
level = atoi(v_level);//v_level is varibale of edit box.
}
|
|
|
|
|
if you want to read of editbox you can use GetWindowTextor GetDlgItemIntor GetDlgItemText

use
UpdateData( TRUE );

u can directly create a int varaiable for the edit control. no need of this..

why using atoi function.. you can use DDX_Text directly for integer value

Thank you very much!
Would you explain to me the difference between UpdateData(FALSE) and UpdateData(TRUE)? I am still very confused about it.
|
|
|
|
|
Thank you very much!
now i need send this data to a socket, do u know how to do it?
Thank you,
yj

yijia_24 wrote: UpdateData(TRUE)?
when u call the UpdateData(TRUE), the values in the control are set to the value variable created for each control.
When u call the UpdateData(FALSE), the values in the variable is set to the correspoding control.
When u call a UpdateData function, it sets/gets all the value to and from all the controls to the variables. some times u may want to take only the text of one edit control. But in that case also all controls in the dialog are upadated. It slows down the program.
U can use the GetDlgItemText() or SetDlgItemText instead of UpdateData()( I recommend this )
