thanks!

1.These two are supposed to take int args: Yet I see them being used a as isalpha('t') etc, i.e we are giving it a char arg. Why is that? 2.I did:

char r[256] ;
int t;
cout << " enter string ";
char c = cin.peek();
cin >> r;
while (c != '\n')

{
  c = cin.peek();
  if (isalpha(c))cin >> r;
}

cout << " tr" << r << endl;
}

but when I put in 'abc%def' i got back the identical thing, not 'abcdef' which is what I expected... 3.Also I wanted to weed out spl chars using isalnum so that an input like abd$ef would get fed in and come out like abdef: char s[256]; cin >>s; but isalnum wont work either... :confused::confused: thanks, ns

Thanks!!!

I have an iterator that is pointing to a certain element. I want to overwrite this element with the next one following it. *I is the current element. But if I do ++I to get to the next element I lose my place.... I dont think *I = *(++I) is quite going to do it. (what would this do anyways? ) :confused: thanks, ns

Thats exactly it!! I had been trying different places to put in the xstring.o but it didnt occur to me to add it to the fMyClass.x line as well. Many many thanks! ns

right, the first arrest is at ' ', but right afterit should choke on 'a' as well...... 23 12 a4 56..... It never prints out *pc = 'a'

I am using strtol to catch bad entries: looping on i { fgets(line, MAX_SIZE -1, fp); pc = line; for ( unsigned int j = 0; j < cols ; ++j, ++col) { num = strtol( pc, &pc, 10); cout << i << " " << j << " " <<num<< " pc " << (*pc==' '?'.':*pc) << endl; line comes from a file that looks like: 9 a5 3 9 1 3 9 5 5 7 10 9 4 6 10 10 8 5 1 7 10 12 1 3 10 10 10 11 12 3 /// an 'a' snuck in...strtol should arrest it, but it never does. (however with a9 5 3 9 3 9 3 8 5 3, I see the letter 'a' in the cout.....) Here is the output for the first case (when a doesnt show...) 0 0 9 pc . 0 1 0 pc .//pc should have been 'a', num is 0 is okay since it didnt get read 0 2 0 pc .//'num' should have been 5 0 3 0 pc . 0 4 0 pc . 0 5 0 pc . 0 6 0 pc . 0 7 0 pc . 0 8 0 pc . 0 9 0 pc . Any ideas why strtol isnt performing as I understand it should? thanks, ns

This is the hundredth time I have made this same mistake.....I say MyClass * ptr, and then blithely do a ptr->method() on it, without having allocated memory which I think is what the problem is here. Many thanks. ns

Appreciate the response.Good to get the go-ahead....:) ns

Theres a container class MyClass which has in it a class MyB (declarted in the h file). I am implementing the constructor of MyB. So in the cpp file does it look like: MyClass::MyB::MyB() { } ? thanks, ns

Wow! Cant wait to try it tomorrow. Thanks so much!!!! ns

Thanks! I'll check. ns

I think I didnt explain right: I want the .htm file to open up in explorer. Its not an exe file. Thanks, ns

I finally settled on this but am still uneasy.

HINSTANCE res = ShellExecute(NULL,"Open", helpFile, "","E:\\\\", SW\_SHOWNORMAL);	

int r = (int)res;

if(r <=32)ShellExecute(NULL,"Open", helpFile, "","C:\\\\", SW\_SHOWNORMAL);

I imagine all I need in the 5th paramtere is the drive letter where the explorer exe is stored. My assumption that its either in E or C is dangerous. How should I handle this dilemma? Thanks, ns

Thank you so much for your detailed response! I see I had totally misunderstood fread! I'll check it out. I had thought CStdioFile and atof was too circuitous but I now see that fread is also doing chars..... thanks, ns

Ok. Will do! Thank you!

Thanks!

Terrific! Many thanks. I also wonder if GetParent()->RunParentFunction() would work.....I will try it. Apprecite your help greatly! I didnt know about the reinterpret_cast....

Cant do those. I am unable to include my view.h file into the cdialog.h file due to deeply entrenched circular includes... So is SendMessage a bad idea?

I need to transmit the pointer of the CDialog to the parent > I am not able to set a member of the parent because it doesnt fit with my scheme. So can I do this? m_pParent->SendMessage(UDM_SOMETHING, this, ndummy) ? Thanks
