So there are embedded CR/LF characters in some lines, or are you viewing it via something like Notepad that is wrapping long lines for you?

Why not check the End Of Line( "\n" ) for each line and then get the first data of each line. You may have to use a while loop for this.

when the data is organized in lines, and hence newline characters have special meaning, I find it easiest to read the data one line at the time. In C fgetline() usually does that for me. Once you have an individual line in your hands, you can scanf() it to your heart's content.

It will happen automatically for controls on a modal dialog box that have the WS_TABSTOP style. For other windows use the IsDialogMessage[^] function.

Im trying to read a file, containing Strings n integers..

This sounds like a course assignment... 
Think about it logically:
x - Find a way to read the file line by line
x - What could you do when you obtain a line?
x - Is there a way to split the line apart, maybe separate name and mark?
x - When you find a way to separate them, it is simply the case of casting the string to an int and visa versa.
If you get really stuck here is a nice link of tools you could use to help with the string:

You cannot cast a string to an int, it must be converted.

@ venomation  what u mention above could be done through oop language but i want to know how to do it through C (sop)

Doing this with C language programming is not difficult; just a few statements.

Have you considered fscanf()?

fp=fopen("SDetails.txt","r+");
while(1)
{
ch=fgetc(fp);
if(ch==EOF)
break;
fscanf(fp, "%d", &myInt);
printf(" %d ",myInt);
sum=sum+myInt;
}
printf("%d",sum);
fclose(fp);
what i did was like above ..but it print the same int 3 times ..i cant find the error...please help
now i can read only ints from the file..thx

What you have will never work as you expect. The call to fgetc() is going to advance the file pointer, then fscanf() is going to be reading from the middle of some byte. Have you checked the return value from fscanf()? If it does not find a number to read from the file, it may be retaining the last read value.
Is your file laid out something like:
Name1,288,7099,441
Name2,1500
Name3,587,208

To disable a button (or any window or control) after it has been created, use the EnableWindow(hButton, FALSE); API call.
To get the handle to the button, use the GetDlgItem API.

I can't seem to get the function pointers working?
anybody see what's wrong? I just want to call the print()method
#include "stdio.h"
class TMyClass
{
public:
void print(){ printf("Print!\n"); };
void (TMyClass::*pt2Member)();
TMyClass(void);
};
TMyClass::TMyClass(void)
{
pt2Member = &TMyClass::print;
};
int main(int argc, char* argv[])
{
TMyClass instance1;
instance1.pt2Member;
return 0;
}

To call a member function using pointers you have to use the pointer to member operators (.* or ->* or ::*).
But declaring the function pointer inside the class is not very helpful.
Usually the function pointer is declared outside the class like this -
void (TMyClass::*pt2Member)() = &TMyClass::print;
The above declaration may be done globally or inside the main function.
In this case, the function call would be as follows -
TMyClass instance1;
(instance1.*pt2Member)();
If, however, you do wish to declare the pointer inside the class like you've done here, the calling syntax would be a little weird and would look like this -
TMyClass instance1;
(instance1.*instance1.pt2Member)();
