Old Thread, but I had the same problem with CRegistry class in Windows 7. But my compiled Program didn`t have the problem, so I just activated the "Run as Administrator" option for my Visual Studio, and CRegistry could read the Registry Keys...

My object is to find the size of the text file without traversing the characters. I wrote the following code:
#include<stdio.h>
#include<string.h>
#include<stdlib.h>
main()
{
int lno=1,n=0,x=2;
long position=0;
char ch[1000],s[1000];
FILE*fp;
fp=fopen("imp.txt","r");
if (fp==NULL)
{puts("Cannot open file");
exit(1);}
printf("01 ");
while(1)
{
ch[n]=fgetc(fp);
n=n+1;
if (ch[n-1]==EOF)
break;
if (ch[n-1]=='\n')
{printf("\n0%d ",x);
x=x+1;}
else if (ch[n-1]!='\r')
{
printf("%c",ch[n-1]);}
else if (ch[n-1]=='\r')
{continue;}
}
fseek(fp,0,SEEK_END);
position=ftell(fp);
printf("\n\n Size of the text file is %ld bytes\n ",position);
fclose(fp);
}
FILE DATA:
Hello
Roger here
Keep it up
Please reply
The size given by this code is 43 bytes while what i am getting on my windows is 638 bytes. Is this right? If yes then Why?

That is all that is needed to get the size of the file.
Or you can use the CreateFile[^] and GetFileSize[^] APIs.

hai all,
in one of my applications, i have to automate a dos level command.
so i construct the command into an str and execute it using system(str).
but in this case, the console window is getting flashed while the command is being executed.
could any one suggest any other alternative to avoid the display of console.
thanks in advance.

Hello,
Is it a Windowed application or a console application? Which dos level command are you executing?
It is a crappy thing, but it's life -^ Carlo Pallini

my application is windowed.
actually, there are some Third party command mode tools which should be used in a sequence to perform some operations on wav files and text ifles.
so i wanted to automate them using a single button click.
and each of those tools print some output also, and i have to process and display that output also.
as of now, iam achieving that by redirecting the output to a text file and reading it back.
i would be pleased if you can suggest any easier method also.
bu my immediate problem is to hide or suppress the console window.
if my questin is not clear please let me know. i will try to explain it better.
thank you.

no the sequence of command which i was talking about may also have them.
Yes, i tried to use the create process. but..
CString str;
str.Format("copy database\\*.* %s>>c:\\output.txt",tempfolder);
DeleteFile("output.txt");
STARTUPINFO s;
s.wShowWindow=STARTF_USESHOWWINDOW&&SW_SHOW ;
int ret=CreateProcess(str.GetBuffer(str.GetLength()),NULL,NULL,NULL,NULL,NULL,NULL,NULL,&s,NULL);
there is no result.
what is the mistake here.

no difference still
iam using it this way.
STARTUPINFO s;
s.dwFlags=STARTF_USESHOWWINDOW;
s.wShowWindow=SW_SHOW ;
int ret=CreateProcess(str,NULL,NULL,NULL,NULL,NULL,NULL,NULL,&s,NULL);
here, str contains the command to be executed.
which is working perfectly when i use it with system().
what is the mistake here?

Try this.
STARTUPINFO si;
PROCESS_INFORMATION pi;
::SecureZeroMemory(&si, sizeof(STARTUPINFO));
::SecureZeroMemory(&pi, sizeof(PROCESS_INFORMATION));
si.dwFlags = STARTF_USESHOWWINDOW;
si.wShowWindow = SW_SHOW;
::CreateProcess(NULL, str, NULL, NULL, NULL, NULL, NULL, NULL, &si, &pi);

securezeromemory undeclared identifier.
this is how the vc++6.0 bangs me. though i included winbase.h.
here i will try to simplify my problem.
say,
str="dir >>c:\\output.txt";
now i want this command to be executed .
can we work in this direction?

The "mistake" is that you are not using SHFileOperation() to copy the folder contents.

You can hide the console if you use CreateProcess by setting the STARTF_USESHOWWINDOW flag and SW_HIDE in the wShowwindow members of the STARTUPINFO parameter. By I don't think you can run an internal DOS command using CreateProcess.

I often use ShellExecuteEx (look it up to know what libraries to link.) This wraps CreateProcess in an easier to use form. I've cut and paste a modified version here.)
To execute a copy; pass "cmd.exe" as the app and "/c command" as the args. Set pDir to the dir where you want the operation to take place. Pass false for show. (The /c tells cmd.exe to execute the command and then exit.)
bool Execute(LPCTSTR pApp, LPCTSTR pArgs, bool show, LPCTSTR pDir)
{
if (!pApp)
{
SetLastError(ERROR_FILE_NOT_FOUND);
return false;
}
SHELLEXECUTEINFO execInfo;
memset(&execInfo, 0, sizeof(execInfo));
execInfo.cbSize = sizeof(execInfo);
execInfo.fMask = SEE_MASK_NOCLOSEPROCESS | SEE_MASK_FLAG_NO_UI;
execInfo.lpFile = pApp;
execInfo.lpParameters = pArgs;
execInfo.nShow = show ? SW_SHOW : SW_HIDE;
char path[MAX_PATH];
if (pDir)
{
execInfo.lpDirectory = pDir;
}
else
{
lstrcpyn(path, pApp, MAX_PATH);
if (PathRemoveFileSpec(path))
{
if (path[0])
execInfo.lpDirectory = path;
}
}
if (execInfo.lpDirectory && !DTDirExists(execInfo.lpDirectory))
{
SetLastError(ERROR_PATH_NOT_FOUND);
return false;
}
if (!ShellExecuteEx(&execInfo))
return false;
if (execInfo.hProcess)
CloseHandle(execInfo.hProcess);
return true;
}

Why does the statement:
printf("This is Raza. \r Who are you? ");
gives the following output.
Who are you?
What effect does the carriage return makes on the text to be printed out?
