hmm, the problem still exists:
one rectangle at the beginning at many after the file (>16)
<br />
wchar_t *gg;<br />
<br />
FILE *wfile;<br />
wfile = _wfopen(L"ReadMe.txt",L"r");<br />
fseek(wfile,0,SEEK_END);<br />
int num = ftell(wfile);<br />
fseek(wfile,0,SEEK_SET);<br />
<br />
gg = (wchar_t*)malloc(sizeof(wchar_t)*num+1);<br />
fread(gg,sizeof(wchar_t),num,wfile);<br />
fclose(wfile);<br />
<br />
gg[num] = '\0';
MessageBox(NULL,gg,L"file",0);<br />

The problem has to do with the FILE structure containing a char type rather than a wchar_t type. Convert from char to wchar_t, like:
char *gg = (char *) malloc(sizeof(char) * num + 1);
...
USES_CONVERSION;
LPWSTR lp = A2W(gg);
MessageBox(NULL, lp, _T("file"), MB_OK);

Can you give me an example what you exactly mean?

okay, but now i only get 3 confusing symbols.

What does your modified code look like? Do you have UNICODE and _UNICODE defined?

hi,
You might want to try:
gg = (wchar_t*)malloc(sizeof(wchar_t)*(num+1));
instead of
gg = (wchar_t*)malloc(sizeof(wchar_t)*num+1);
also, are you sure your file is in UNICODE format where each character is 16 bit wide?
|
|

In the project options i defined that the linke should use unicode instead of ascii.
Now i also tried yours but without an effect.
The file was written with notepad and i used the save as option and selected unicode as charset.
Okay but now, i am a little bit confusing. i am not sure if i need this for my further learning cycle? Iam actually learning the winapi, but i think for productional use it would be better if i directly use the unicode file stream classes or the windows createfile function to read a file or not ?
So i think its not important or i am wrong?

It actually all depends on the project requirements, but I suppose its better to create projects with UNICODE defined and keep your textual data in unicode format. Prefered in my opinion should be UTF-8 which uses less space.
If you are loading a text file you should somehow know its encoding type. If you are using Notepad to save text in Unicode format then file contains some extra information bytes about actual encoding type - it is easy to see them in binary file view. Some info on actual notepad format encoding can be found here:
http://blogs.msdn.com/michkap/archive/2007/04/22/2239345.aspx[^]
There are some other errors in your code that might be the cause of the errory you describe. For example ftell() return length of the file in bytes..., here is a code I got working quite well:
wchar_t *gg;
FILE *wfile;
wfile = _wfopen(L"c:\\ReadMe.txt",L"r");
fseek(wfile,0,SEEK_END);
int num = ftell(wfile);
fseek(wfile,2,SEEK_SET);
int buffSize = sizeof(wchar_t)*(num/2+1);
gg = (wchar_t*)malloc(buffSize);
memset(gg, 0, buffSize);
fread(gg,sizeof(wchar_t),(num-1)/2,wfile);
fclose(wfile);

In my program, I need to look a directory and copy the filenames in that directory and display the same in my own listbox for a User to select. I want the finding and copying the files names to be done without a Users intervention - strictly behind the scenes activity. Anyone know how I can do this. (VS2008 C++ in MFC.)
Code would be nice. I used CString extensively.
Thanks in advance.

Do you need to DlgDirList or FindFirstFile/FindNextFile?

WIN32_FIND_DATA would be one of the options along with FindFirstFile etc.

 didn't get how would the user be intervening in this process of finding the files once you have the name of the directory and so it's path.

I have just started working on your requirement. Would give you an optimized code soon that is specific to VS2008 C++ in MFC. You can transfer some amount [in cash please] to my account for the work that I do for you. 
Somethings seem HARD to do, until we know how to do them.

Use this code to find all files in a directory:
CString szFile, szDir = _T("D:\\CodeProject\\Trial\\res\\*.*");
CFileFind CFind;
BOOL bFound = CFind.FindFile(szDir);
while(bFound)
{
bFound = CFind.FindNextFile();
szFile = CFind.GetFileName();
CString ext3=szFile.Right(3);
CString ext4=szFile.Right(4);
if(!szFile.IsEmpty() && (szFile.GetLength()>4))
{
}
}

Hi experts,
I have one application that enumearates ports..
when i buld my application and execute it runs fine..
but when i copied it to other PC
or another User of my PC then it gives me a exception
" The application failed to initialize properly (0x8000003). becoz of Congfiguration is incorrect.."
can anyone help me..its urgent...
what should I do?
Thnaks in advance..

Try decreasing the desktop resolution. Applications fail to initialize properly at very high screen resolutions. Also, try executing the application with different desktop wallpapers.

ok
thanks for reply..
I already check all these things...
and my application is console based ..
so i think there is no need to change display settings,.
is there any other solution>
or any settings in VC++ project settings have to do?
reply.

Right now, with the information that you've given, changing the desktop wallpaper is the only solution I know.
If you want a more proper solution, give more details. Read the sticky post (guidelines) at the top of this forum, which says "How to get an answer to your question". Follow the guidelines and you'll get an answer.

That's because it was a joke.

Is the application compiled in debug or release mode? Does this other machine have all the necessary DLLs installed? See here for more.

You should look for all the DLL's or modules that your application is using to be loaded in the other computer, do you have some registry keys that are being used? and do those keys are in the other computer? do you have any configuration file that you are accessing without controlling the result and the file is not there? have you searched for that error code in google or in MSDN? Are you using an activeX control in your application? and if you are using it, have you registered it on the other computer? The operating system version is the same? it can be that you are using an API that is not present in the other OS...
And tons of things more...
Why don't you post something more accurate?
PS: if you are not getting anything, then try it in the old-school way: remove/comment parts of the code until you can see why do it happen...

This problem occurs when the side-by-side assemblies listed in the application manifest aren't present. Most likely this is the C++ runtime if you're using Visual Studio 2005 or later. Use vcredist_x86.exe to install the runtime.

Excuse my ignorance on this matter ...
I am trying two write a small app that copies files from an Intranet server. If I access the directory on the server using Internet Explorer I get a Web based directory listing. I think it's an apache/Linux server. I would like to scan through the directory like you can using FindFirstFile and FindNextFile (which does not work), but I can not see how to do.
My expertise is C++ / MFC.
