No, if file is null I cannot call ReadString().
As I have told already ReadString works fine and gets line by line in while() loop.

|
|
|
|
I have tried.. it does not work too..
SO I think you'd better change the file format to DOS format at first.

I did it first time I have beed sure about the bug is exactly a bug.
So... I'm sure this is just a dirty Microsoft's trick.

for data file "00000000h: 31 31 31 31 31 31 3D 0A ..."
my function returns "111111="
for the second time, it returns "", I think I should increase g_fPosition.
But the GetPosition is OK anyway.
/////////////////////////////////////////////////////////////////////////////////////////////
//
/////////////////////////////////////////////////////////////////////////////////////////////
char gchOneLineNews[1024];
FILETIME g_ftWrite = { 0, 0 };
ULONGLONG g_fPosition = 0;
char * GetOneLineNews(char * pFile);
/////////////////////////////////////////////////////////////////////////////////////////////
// Get One Line News from the File, (read next line, check the write time)
/////////////////////////////////////////////////////////////////////////////////////////////
char * GetOneLineNews(char * pFile)
{
#if 1
FILETIME ftWrite;
UINT rt = 0;
CStdioFile file;
CFileException ex;
if (file.Open(pFile, CFile::modeRead, &ex))
{
if (GetFileTime(file, NULL, NULL, &ftWrite))
{
if(0 != CompareFileTime( &ftWrite, &g_ftWrite )) // not same
{
g_fPosition = 0;
g_ftWrite.dwLowDateTime = ftWrite.dwLowDateTime;
g_ftWrite.dwHighDateTime = ftWrite.dwHighDateTime;
}
file.Seek( g_fPosition, CFile::begin );
if ( NULL == file.ReadString( gchOneLineNews, 1023 ))
{
g_fPosition = 0;
file.Seek( g_fPosition, CFile::begin );
file.ReadString( gchOneLineNews, 1023 );
}
g_fPosition = file.GetPosition();
}
else
{
rt = -2;
}
file.Close();
}
else
{
rt = -1;

Hi, all.
I wrote a code to execute file with shellexecute function.
Since I wanna find the executable program of specific file, I use FindExecutable function.
However, I wanna make sure that the result of FindExecutable fuction is really executable program name.
I found PathIsExe function in MSDN Library, but it can't be run in Win 95 or Win 98 according to MSDN Library.
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/shell/reference/functions/shellexecute.asp
I can't remember the function name that does the same work as PathIsExe.
Could you please help me to find API or other function that does determine whether a file is an executable by examining the file extension?
Thanx in advance.

"FindExecutable retrieves the name of and handle to the executable (.exe) file associated with the specified file name." (MSDN). Calling PathIsExe after FindExecutable seems redundant to me. Maybe I am not understanding your question properly.

First of all, Thanks for reply.
Actually, I wrote a code just with FindExecutable and Shellexecute.
However, FindExecutable sometimes doesn't return properly executable program name and path.
So I want to check whether the result that FindExecutable returns is properly executable program name (i.e. by examining the extension)
And I found "PathIsExe" function, but it only supports Win2000 ir higher.
As a result, I'm looking for API or some kinds of function that does the same work as PathIsExe.
Sorry for ambiguous question.

You are welcome. Sorry but I can't really help you because I have never used PathIsExe.

There's little magic behind PathIsExe, the docs say that it
returns TRUE if the file extension is .cmd, .bat, .pif, .scf, .exe, .com, or .scr. Returns FALSE otherwise.
So, you shouldn't have any problem with writing your home-made version of PathIsExe.

Hi,
I used RasDial function for dial up connection.
It’s works fine in win2000, winXP and some of the win98.
My problem is, some of the win98 machine it doesn’t work.
Could you tall me, why didn't work in win98.
Here is my code:
DWORD dwRet = RasDial(NULL, NULL, &rdParams, 0L, RasDialFunc, &g_hRasConn );
|
|
|
|
|
Which value has dwRet upon error?

Thank you for reply.
error is: "Cannot find the phone book entry."
this error is only occur in win98.
if you know the solution then please reply.
|
|
|
|
|
I've got a hunch. There's a well known bug n Win95 (maybe it has survived in 98) that causes RasDial to fail with this error code when:- No entry name is specified
- and no dial-up connection is set up in the system.
The only solution I can come up with would involve creating a dummy entry (with RasSetEntryProperties) even if you don't use it later on. Please report back if you try this.

hi,
i try with RasSetEntryProperties but it return error code 87.
here is my code.
RASENTRY RasEntry;
DWORD dwEntryInfoSize, dwRet;
memset(&RasEntry, 0, sizeof(RASENTRY));
RasEntry.dwSize = sizeof(RASENTRY);
dwEntryInfoSize = sizeof(RasEntry);
sprintf(RasEntry.szLocalPhoneNumber, "89188888");
dwRet = RasSetEntryProperties(NULL, "MY CONNECTION", &RasEntry, dwEntryInfoSize, NULL, 0);
now what can i do?

Hey Friends Can someone suggest how we can customize the Grippers displayed when using CRectTracker class.
I wish to use the Style ,any suggestion for using the style CRectTracker::resizeOutside,how about using multiple selection and multiple control tracking .
|
|
|
|
|
Your best bet is to derive a class from CRectTracker and override the "Draw" function. Copy and paste the existing CRectTracker::Draw code and then modify as desired.
If you want multiple selection then search CP - I'm sure there have been articles that cover this.

Dear Robert Edward Caldecott
I tried the Copy And Paste But.............
In the debug mode the execution goes in OnDraw but the Output is the same old one even if I simply put a return statement ie no code for My CRectTracker inherited Draw Function.Can U Pl give it a one more try .
|
|
|
|
|
Then try overriding DrawTrackerRect instead.
When I am king, you will be first against the wall.

Wollah ..................
Yes You Were Right at the First Place.
Actually I Suppose Draw is Not a Virtual Function And I Was Creating an object of CMyRectTracker but using a Pointer of CRectTracker,I figured it out ,tried it again and Yes It is Working I am able to draw RED Coloured Grippers which I suppose I can change according to my need,
Thanks,Thanks ,Thanks.................................................

Hi~~
i have a string containing an hex number and i want to convert it to an integer.
--------------------------------------------------------------
char *temp = "0x3e40";
i want to convert it to an interger.. which is 15936
how do i do that?
Thanks
|

|

unsigned long nValue = 0;
long nConverted = sscanf (temp, "%x", &nValue);
if (nConverted != 1) {
failure;

you could also use:
char *temp = "0x3e40\0";
int iNum = atoi( temp )

Although atoi only converts base 10 numbers - strtol (temp, NULL, 16) would be correct for hex!
