I have a linux application, that i want to use to find and manually read/edit the windows Vista/7 BCD file. I cannot run any existing win32 applications, I need to hard code one in C/C++
Please help
Thank You

My problem is that the windows Boot Configuration Data is a binary file, which cannot be accesses directly, and since my working environment is Linux, I cannot use any Microsoft released code or any third party windows application
So where can I find information on how to read and modify the windows BCD using linux (like how is this file structured etc.)
Thanks a lot

You could try using CRT code to read from the c:\boot\bcd file. If Windows is up and running, however, it my have that file opened/locked exclusively.

I'm sorry, I'm not familiar with "CRT code" could you also please suggest some resource where I can find out about this?

Hello,
I'm a developer and one of my faved languages is C++. Now I've been coding a lot with Visual Studio and I can do lot's of things with C++. Time to time I get interested in Linux projects, Opensource libraries and other stuff. So I tried to use Eclipse in various ways to work out my C++ stuff, but I get so much in trouble that I give up before even writing a few lines of code. The problem is that I get confused with using Eclipse CDT, the Linux handles libraries and dependency nightmares. For example, I install a library, say Libxml++ (which is a c++ wrapper for libxml). Now apt (using ubuntu) will install it in /usr/include/libxml++-2.6/libxml++ . The include files then get nervous as they reference simply <libxml++ stuff.h="">. So GCC, and it will complain with errors. Now this is the usual kind of problem I get in when I try to do such things. And I end up posting to forums, getting a reply days later, solving the problem in an impossible to know way, while in the meantime I lost any interest in what I wanted to do and I just don't go on with it anymore. Now as it is the nth time I get into this, I ask: is it so complicated or is it just that I miss some reading, some special reference???? Is it possible that on visual studio you can code thinking about code, while on linux you have to spend so much time in setting up the environment??? I'd be really interested in using OSS software and libs, or even partecipating to projects, but it is so difficult to get in. So, what are your suggestions? What should I read, do, experience?

When you install Visual Studio, you are installing a lot of libraries for working with the OS and a lot of associated libraries. But if you install any other third-party libraries (like libxml++, for example), then you'll go through similar pain as with Linux development.
You either need to set environment variables to tell GCC where to find header and library files[^], or specify those directories as suitable GCC options in your makefile (or project file, if that's what Eclipse CDT uses).
For example - I program on Mac OS X (which is Unix underneath the GUI). I have the following environment variables defined to find Boost and the libraries I've installed with MacPorts (equivalent to Ubuntu's apt-get):
CPLUS_INCLUDE_PATH=/usr/local/include/boost-1_38/boost/tr1/tr1/:/usr/local/include/boost-1_38/:/opt/local/include:
LIBRARY_PATH=/usr/local/lib/:/opt/local/lib:
So, I've just added libxml++ (or libxmlxx as MacPorts calls it):
sudo port install libxmlxx
---> Fetching libxmlxx
---> Attempting to fetch libxml++-1.0.5.tar.bz2 from ftp:
---> Attempting to fetch libxml++-1.0.5.tar.bz2 from ftp:
---> Attempting to fetch libxml++-1.0.5.tar.bz2 from http:
---> Verifying checksum(s) for libxmlxx
---> Extracting libxmlxx
---> Configuring libxmlxx
---> Building libxmlxx
---> Staging libxmlxx into destroot
---> Installing libxmlxx @1.0.5_0
---> Activating libxmlxx @1.0.5_0
---> Cleaning libxmlxx
I know port installs into /opt/local. Sure enough, in /opt/local/include, I see a directory for libxml++-1.0. I now know that to use libxml++, I can add /opt/local/include/libxml++-1.0/ to CPLUS_INCLUDE_PATH or (and this is more likely) I can add the option -I/opt/local/include/libxml++-1.0/ to the gcc command-line.
g++ -c -O2 -I/opt/local/include/libxml++-1.0/ program-that-uses-libxml++.CC
If you use a makefile, then add -I/opt/local/include/libxml++-1.0/ to the CXXFLAGS make variable:
CXXFLAGS += -I/opt/local/include/libxml++-1.0/
That will add the include folder option to the gcc command line only when compiling C++ files.
HTH!

can any body help me out what is this error.or does we have to include any lib or header file to include.

It's contained in the Exchange Server 5.5 SDK samples. Microsoft no longer supports Exchnage 5.5 and this link[^] seems to be the only link that contains any useful Exchange 5.5 stuff - including the function you want. Look in the LibSamples/AddrLkup (think that's what it's called) directory - the function source code is in there.
BTW - if yu don't already have the Exchange 5.5 SDK, you're out of luck. That function requires that SDK and Microsoft have pulled it.

Hi everyone
I have one question about the perfect way that can help me find what I need (functions,classes..or libraries) for example if I want to find all functions to run any program from my program,what is the point should I start my search from it?
could anyone help me and explain her/his way to find any function from a hundred functions exist in VC++.net development environment

On first reading this sounds like a bit of a daft question, but on thinking about it I can see what you mean. If you're not very familiar with .net and all it contains, then trying to work out which classes, methods or events are relevant to your problem can be quite difficult, and a lot of work.
Even those of us that do know it reasonably well (at least I think I do) can still sometimes get confused trying to find the best way to do things.
I don't know what other people do, but I generally start with Google, and use a search string that narrows down the results as much as possible. Be very specific, and think about what it is you're trying to achieve, what your problem is, then add extra search terms to look for specific information areas.
For example, someone was asking very recently about drag and drop in a ListView control, so I would search on Google using something like :-
"drag and drop" .net C++ ListView
which gives a lot of very good results.
Or, for the question below, on detecting screen resolution changes, I used :-
.net c++ windows detect screen "resolution change"
The Code Project articles are also a very good source of information, and using the advanced search mode there can also narrow down the results to the language or platform you're interested in. And there are a few other forums which have good articles and knowledge bases.
Finally, make sure you have Intellisense turned on, and have a browse through it - you can learn a lot about what a particular control, type, object etc. can do just by looking at its properties, events and methods.
There are three kinds of people in the world - those who can count and those who can't...

Hi!
I need to detect screen resolution change cause i am working in a toolbar that docks in the borders of the screen.
Thanks

Easy peasy.
Handle the WM_DISPLAYCHANGE message.
Nnnnext!

If you us the GetSystemMetrics Function[^]
int x = GetSystemMetrics(SM_CXSCREEN);
int y = GetSystemMetrics(SM_CYSCREEN);
On a multi-monitor system you can use SM_CXVIRTUALSCREEN and SM_CYVIRTUALSCREEN.
You could also use the GetDeviceCaps Function[^]
int x = GetDeviceCaps(hDC, HORZRES);
int y = GetDeviceCaps(hDC, VERTRES);

There's a system event which should be what you're looking for documented here.[^]

Hello all,
I am currently trying to do a project where I convert AVI files into MP4 and I was planning on using directshow to do this. Does anyone know where I might be able to find a filter which does the job for me. I would prefer this to be open source and free if possible.
If no one knows where I can get such a filter could anyone suggest somewhere I might find some info about performing the transform as I am struggling to find anything of use at the moment.
Thanks for the help.

FFMPEG[^] is a free open source project that supports almost all heard of formats.
But I think you cannot compile it with Visual Studio. But you could use its binary.

Hello Guys
I have got an array of chars for example: char[0] = 'C'
char[1] = '\0'
char[2] = '+'
char[3] = '+'
Now i ve got a problem how to put this chars in BSTR,
so that i can have a BSTR with embedded NULL cahr?
Or how can i create a BSTR with embedded NULL char in the middle?
Any ideas?
|

BSTR is finished with a NULL char although it has a fixed length.With an embeded NULL char may cause program-exception.But if you insist to do that,check these code:
{
BSTR bstrTest = SysAllocString(L"C+++");
BYTE *pByte;
pByte = *(BYTE **)(&bstrTest);
*(pByte+2) = 0x00;
//bstrTest is your BSTR {0x43,0x00,0x2B,0x2B}
//print the fixed length
printf("the length is %i\n", SysStringLen(bstrTest));
//print the raw BSTR data
printf("the 1st unicode raw data is %x %x\n", (BYTE)(*pByte++), (BYTE)(*pByte));
pByte++;
printf("the 2nd unicode raw data is %x %x\n", (BYTE)(*pByte++), (BYTE)(*pByte));
pByte++;
printf("the 3rd unicode raw data is %x %x\n", (BYTE)(*pByte++), (BYTE)(*pByte));
pByte++;
printf("the 4th unicode raw data is %x %x\n", (BYTE)(*pByte++), (BYTE)(*pByte));
pByte++;
printf("the end raw data is %x %x\n", (BYTE)(*pByte++), (BYTE)(*pByte));
}

Hello,
I wrote an mfc application using vc 2008.When UI tried to test my application on other computers I am getting "Application is not confiured properly" message although I copied required dlls.Tested systems are Windows Xp and Vista.My own system is Windows Xp and I have vc 2008 installed.Running properly. What is missing on the test systems? .net 3.5? or latest service packs.

Thanks David,
I copied dlls manually.I recently download redist package. I see that package does some additional configurations on the system(not just a dll coppy ).I hope It is going to solve my problem.Thanks for your prompt answer
Best wishes
