   " What can be possible reason for that ? I am not getting why this happens I doubt it's because less graphic capability ...

Is there any code review tool for VC++?
|
|
|
|

Not sure what you mean by a "Code review tool" but generally I find a text editor, eyeballs and a knowledge of the idioms of the programming language handy.
Do you want something like lint that does a static analysis of the code? If so then have a look at PC-Lint and, if you really have to run it from inside Visual Studio, Visual Lint (IIRC) from Riverblade software.
Cheers,
Ash

the typical tool is something that can do a batch 'diff'. something like BeyondCompare.

It appears that you are setting the color of every vertex of the triangle fan and letting OpenGL determine the colors of the pixels inside the triangles. I think that's the right way to do it but you probably don't want to use white for the color. You will be unable to see most shading effects if you do.
For texture mapping you define the [u,v] coordinates on the texture that each vertex maps to and this requires some computation on your part. There are many different algorithms for this and the one to use depends on how the texture image was "unwrapped" from the sphere. This is the same problem faced by cartographers when they draw maps of planets. They have to unwrap the surface of the sphere onto a 2D image. In your case you need to know how that was done so that you can reverse the process.
BTW - [u,v] refers to the (x,y) coordinate in the image that is used for a pixel's color.

I have a win32 api program which will fetch text from a server and will display it in a multiline text box.
The information is not saved using this program but it just fetch the information to display it for the user.
I give the users an html GUI to save information in UTF.
the html interface is working well like saving Western European characters.
When i display it in the text box i get two junk letter instead of the actual Latin alphabet.
How do i notify or stylize the text box to display extended characters (latin) ???

Is your application being compiled for UNICODE? Check under General Properties for the project. If yes then it should handle Unicode characters automatically. If No then you will need to provide conversion between Unicode and MBCS.

Sorry i have replied very late.
Yes. I have defined the UNICODE and _UNICODE directives.
I have to mention here that i am using DEV C++ IDE (gnu gcc compiler collection).
The problem is with this IDE and not vc6.0.
In VC6.0 the text boxes are not even accepting unicode chars. Where as when i compiled with DEV c++ ide... the only problem is displaying it as unicode but the text boxes accepts unicode and i can directly type in the unicode strings in message boxes. I tested the message box by directly giving the strings. it worked.
Since DEV c++ is not used by people here i have to find it of my own...
I followed MS document to use unicode in VC6.0 but i cannot save unicode static text in string tables.

VC6.0 is very old now, we have gone through 2002/3 - 2005 - 2008 and are now on 2010. I would suggest that if possible you upgrade to VS2010. If it's a question of cost then you can get the free Express Editions[^] from Microsoft.

Yes. I am in parallel creating the same application in C# because i cannot do many things in VC6.0 like unicode and SSL(for my socket programs). But i thought i can know the core of windows if i am sticking to VC6.0. I dont know mfc i want to be good in win32 API programming. I hope this can be done in .NET too... It should be. Thank you.

Then I suggest you follow my previous recommendation and get a copy of the free VS 2010 Express Edition C++ system, which will help you learn all about Win32 programming without any requirement to learn MFC.

I have(me and my friends) already got 2005 and i am a beginner to .net framework. Do i need the latest 2010 version?

The 2005 versions are also a bit old now as we have been through 2008 and are now on 2010. However it is not absolutely necessary to use the latest version if you are just learning; I leave it up to you to decide when to upgrade.

Hi experts
I have to migrate some projects from VC 6.0 to visual studio 2005. Is Anything required to achieve it and what waht kind of problem i can face? As far as my knowledge is concerned, All upper version products automatically converts the project from older version to new one.
With regards

you will probably have to fix a lot of these:
for (int x=0...)
{
}
for (x=0;...)
{
}
the scope of the first x is limited to the first for loop, after VC6.

You will likely run into Unicode-related issues. That and variable scope are the two biggest issues I've faced when porting one to the other.

Yes, it converts the project, not the code.

Why VS2005? Consider VS2008 or VS 2010 (though the latter is a bit of a moving target still).
The step from VC6 to VS2005 is the big one though.
Upgrade Wizard will (try to) port your project files - this usually works ok - but you are alon wiht changes requried to your source code.
Compiler: VS 2005 provides improved standard compatibility, the most common issues being for scope, more rigorous checking of templates, and other minor things. For a list of breaking changes, see here[^] and here[^].
Unicode: Project settings now default to unicode. Moving from ANSI/MBCS to Unicode is a completely different story, you may want to take this as a separate step.
"Safe" CRT functions - many functions of the C/C++ Runtime will now generate a warnign that they should be replaced by safe counterparts - mostly to avoid potential buffer overflows and encourage more rigorous error checking. This is often a barrage of warnings, burying everything else under it. For more information, see here[^].
IDE + Build Performance - Get a really good computer. I mean it.
Windows Headers - we had some problems with some of the more arcane windows library headers moving some declarations around, requiring ugly include reordering and supressing some declarations being made / imported. That's unlikely to bite you, but can be an immense time sink.

Hello how are u?
I am new here and I have a great problem with my WinCE 5.0 application. I want to call an .NET application by my own developed prog (C/C++). I use the function
CreateProcess(_T("/flashdisk/app.exe"), NULL, NULL, NULL, FALSE, CREATE_NEW_CONSOLE, NULL, NULL, NULL, &ProcInfo).
If I run my prog the CreateProcess function returns SUCCESS but the other prog cries " .NET CF Initialization Error!
The Application failed to load required components... Support info: -2147479552 (80001000)".
If I doubleklick the other program in the WinCE explorer the application starts with no error message.
Under WinCE6.0 I don't have this problem. Do I have to run an other application first before starting the other prog?

I assume you are talking about a Knowledge Transfer; then why not spell it out so everyone can understand the question? However this forum is for C/C++/MFC questions so I suggest you post in General IT Issues, Collaboration or some more appropriate place.
