Something *might* exist but I'm not aware of anything.

I was thinking something probably does exist, I just don't know about it. If you do find somehting, let me know.

Thanks.

since you have to redo all of the "connections" ( callbacks and all that junk ) in VB, I think that it might be faster to just redo the forms in VB ...

maybe there's an .rc import in VB ?

Font size: point ang logic

followings are copied from VC help (in LOGFONT)

===========================
For the MM_TEXT mapping mode, you can use the following formula to specify a height for a font with a specified point size:

lfHeight = -MulDiv(PointSize, GetDeviceCaps(hDC, LOGPIXELSY), 72);
============================
the value GetDeviceCaps(hDC, LOGPIXELSY) is 600;
so formula above is:

lfHeight=-PointSize*600/72;

if PointSize=90,
lfHeight=-90*600/72=-750.

I think the result is incorrect.

what is problem?

Looks right to me: 90pt is roughly 1.25", so if an inch is 600px then 750px should give you an inch and a quarter (the correct result). Why would you think this is wrong?

when to upgrade vc6?

hello,
i've been using vc6 standard edition for a few years now, developing various c++ and MFC applications; i looked at microsoft's visual studio web site, and was overwhelmed by the choices. is there any downside to staying with good-old 6.0? if so, are there any recommendations regarding express versus standard versus professional versus super-extra-special? all i want to do is c++, and mfc if it'll continue to be supported (i'm having my doubts about that).
thanks,
ed

apologies if this is the wrong discussion board for this question....

This questions been asked over and over again, everytime nobody ever seems to get a definative answer as everybody seems to have a different option on it. Smile | :)

The only reason I can see not moving from VC6 would be because of legacy code, over the last few versions Microsoft have made some quite big changes to the compiler for standards compliance, etc while no a huge biggie for small projects I wouldn't want to have to go through that much heartache of if I could help it.

The newer editions of VC include Managed C++ (very cool) so you can switch in and out of .NET whilst still using MFC or Win32 code. MFC has had a bit of a revamp in places and the compiler now supports the x64 architecture. On the downside, the IDE is now way more bloated and VS 2005 is definately slightly slower because of it.

If your doing any MFC development the Express edition isn't going to be for you, it simply isn't included in the package.

Personally, I'm running VS 2005 and theres no way I'm going back to anything less - I like it, ask somebody else and they'll tell you different Smile | :)

Anyways, for a full list of the differences between Visual Studio 2005 editions have a look over on MSDN[^]

Which makes sense. If a definitive answer was provided, it would no longer be an opinion, but a fact.

I expect VS 2005 Standard Edition will be adequate for what you want.

thanks for all your suggestions; i'm using only a small part of stl (i should be using more), so that's not a major problem for me. i guess i'll stay with vs6 until i need features that it doesn't have, or until i need to support an OS that it doesn't support.
it also seems from your posts that mfc will be supported going forward, which is a separate issue but still good to know.
thanks for all your help!

Read tab delimited file

kelprinc1-Feb-06 3:39

1-Feb-06 3:39

Does anybody know how to read a tab delimited file at the same time using the '\n' as a delimiter if its encountered first.
I tried using getline(buffer, num_chars, '\t')
It works fine when i know the number of columns.

Say i had a file like

line1:Col1 Col2 Col3
line2:Col1 Col2
line3:Col1 Col2 Col3

using getline(buffer, num_chars, '\t') would return
Col1 Col2 Col3 Col1 Col2 Col1 Col2 Col3
everything in one line.

I tried defining a macro like #define tab_eol '\t'|'\n' then use it as
getline(buffer,num_chars,tab_eol) but it does not really work

Any help Please

perfectly useless buddy...

consider this to understand why :

'\t' | '\n' = 0x09 | 0x10
            = 00001001 | 00010000
            = 00011001
            = 0x19
            = '\031'
            = DC3 character...

Does strtok() help?

Thanks but strtok() does not work well if you have empty columns. i.e concurrent tabs

David Crow2-Feb-06 2:45

2-Feb-06 2:45

True. You could always make your own version of strtok() that does not skip leading delimeters.

I managed to sort out the problem by reading the whole line into a istringstream object then tokenize the object using the getline method and '\t' as the delimiter.

But for interest sake how wld you do it?

I guess that would depend on several factors. Am I limited to just C++ code? Is it a console or GUI application? What is my state of mind at that moment?

Glad you got it going.

Are the entries (e.g. "Col1") allowed spaces in them? If not this will do won't it?

#include <iostream>
#include <string>
using namespace std;

// Somewhere...
string entry;
while ( cin >> entry )
{
     cout << entry << endl;
}
