I have a dialog with about 5 CEdit fields,
CEdit1, CEdit2,..... CEdit5.
Currently, when I clicked the TAB key,
the cursor will jump from CEdit1 to
CEdit3 instead of CEdit2.
Can someone tell how to fix it?
Thanks,
Kevin

open dialog in resouce editor for which you want to change tab order. Then in the menu you will see format, there is taborder option in it, click it and you will be able to change tab order by clicking controls in the order we you them to be selected when pressing tab.

I've seen in many source codes, some statements written in #if 0 block something like:
#if 0
printf("Blah Blah");
#endif
Please tell me what is the meaning of #if 0 in the code above.

it simply means the code in side the block is ignore for compilation and will not appear in the final build.
it is similar to saying
#if !defined(SOME_BUILD_FLAG) or<br />
#if FALSE<br />
<br />
#endif
since the dev wanted the code to be explicitly removed from compilation he used
#if 0<br />
#endif
directive

Then what is the purpose of the code inside that block ?
For example, if the code is written in #ifdef DEBUG block, it is skipped in the release builds but its purpose is clear and that is: it will be compiled in debug builds. So what is the purpose of writing code in #if 0 when i'll never be present in the executable.

There are many reasons to use
#if 0
Actually, I do it all the time.
Here is my reason.
Let say I re-write some code/method/function
and I think it should work.
But I would like to keep the old code
around. Just in case......
I know I can retrieve the old code
from the source control. However, it's
more convinence if I have the old
code right next to the new code.

I hate #if 0 . It's not so bad if the code commented out is small, but when large pieces of code are bracketed with these you can find yourself analyzing code only to find, when you get to the top, that you've been wasting your time and the code isn't even part of the product. This has happened to me many times. If the programmer simply commented it out the syntax highlighting will stop such problems from ever occurring.

me too.
i use this purpose instead...
#ifdef DEBUG
#define DPRINT printf
#else
void DPRINT(...) {}
#endif
this way, in debug mode, we could DPRINT() something, which will not been took in account in release mode (and more, the compiler will optimize a call to DPRINT() in release).
for instance :
int Foo() {
DPRINT("Foo()\n");
int i = 654;
DPRINT("Foo output : %d\n", i);
return i;
}

you can #if 0 the code which needs to be ignored in both debug and release build, i.e. older logic to solve a problem, etc.

Yes steve u r definetly correct. But this is not supposed to be used to large chunks of code. it is more of an debugging approach than just saving old code.
Tip: Always it is a good option to try to put a breakpoint to know if this code is compiled or not. a breakpoint cannot be inserted in any code that is not compiled.
Hope this helps.

But nested comments are not allowed. That's where #if 0 is of use.

I agree that large blocks of #if 0'd code are annoying but VS2005 improves things a lot by greying it out. It even greys out (for example) #ifdef _DEBUG blocks when _DEBUG is not defined.
The opinions expressed in this communication do not necessarily represent those of the author (especially if you find them impolite, discourteous or inflammatory).

I believe that in Visual C++ 6.0 there is a key combination that will take you to / from
#if
and
#endif
but Microsoft in their 'wisdom' removed this very handy functionality from VC++.NET 2001. Yes, thanks Microsoft...
Personally, when I need to comment out large chunks of code, I use
#if defined dfkagtljarogh
#end if // defined dfkagtljarogh
where dfkagtljarogh is the result of some random keystrokes. Copy and paste to make sure that two instances match, and then it is not too bad to use Find to jump from beginning to end or vice versa.
And as for being unable to nest /* ... */ comments in C++, this is an abomination that should never have been put into the language. Is there any reason whatsoever why C++ (or C even) HAVE TO REFUSE to allow such useful nested comments?
Thanks again, Microsoft. Some C++ compilers do allow this.

yes i agree with you and that is one thing that I hate in VC++ compiler.

I have small webserver which is able to handle html files only by default. But now I need to enable it to process ASP page. Is it possible or is any component available ? 
|
|
|
|
|
which webserver are you talking about ?
it would depend if that webserver has support for ASP or has plugins to process ASP.
IIS has ASP engine that can be installed to process ASP.

I have source code of a simple web server. So I have my own web server. Now I want my web server to process ASP coding. I should not install IIS/PWS.
|
|

|

Like I said your new webserver should provide a plugin to process the ASP script.
like you said it is a simple webserver, it has probably just implemented the HTTP protocol, i.e. deliver the content on clients request.

I am trying to develop custom visualizers for native code in Visual Studio 2005. As I understand they were available for native code in beta's but were removed from release version.
So I am thinking to add a custom menu in code window contextmenu, hook with debugger, get the data for selected variable, identify type using RTTI or provide a dialog where user can enter types and then render it. Is this approach fesiable?
Another problem I have is there is not enough documentation for extending VS IDE using native code. So right now I am not even able to add a context menu on right click. I can see the menu I am trying to add sometimes but add-in always crashes. I tried articles on CP and none of them added a context menu in native code. Any pointers or advice for articles or samples will be much appreciated.
thanks,
-Saurabh
