Runtime Error!
Program:..... .exe
This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information.

the error is about this sentence.
pConnectRead->Open(commandString, connectionString, adOpenStatic, adLockReadOnly, adCmdText);
can this be helpfull to GUESS the solution.

Usually this type of error occur due to IMproper/unreferenced Memory allocation.

have you checked that is pConnectRead hold valid memory or any of it args!

CFileDialog fileDlg(TRUE, NULL, NULL, OFN_HIDEREADONLY | OFN_PATHMUSTEXIST, NULL, this);
if(fileDlg.DoModal()==IDOK)
{
sSelectedFile = fileDlg.GetPathName();
}
I guess the problem is about the above code, when i use this dialog window the error happens. But if i use the files path name by editing the editbox there is no error.
But still cannot use this dialog
|
|
|
|
|
At the end i find the solution. its about an ugly problem. When we use CFileDialog without OFN_NOCHANGEDIR, it doesnt release some of the handles, and system crashes...
dlg = new CFileDialog(FALSE, NULL, NULL, OFN_HIDEREADONLY | OFN_NOCHANGEDIR);
this solves everything...

I have a dialog based application which runs fine on NT and 2000. However, it doesnt work under XP. I have done some traces, the application gets invoked, but the main dialog window does not appear. Any ideas?

May be its problem with controls (especialy when using CustomCtrl) in your dialog.
|
|
|
|
|
Create the dialog with the DS_NOFAILCREATE style. If that works, then you know there is a control-related issue. This is normally because an ActiveX control is being used that does not exist, or has not been registered, on the target machine.

hiho@ll
i'm using this http://www.codeproject.com/library/lyoulhttpclient.asp http client to upload a file (like the example)
what i do:
i'm uploading a few text files, not very big, 1 or 2kB
the problem:
i can upload (to my self programmed php script) 2 files
the third file doesn't work
HttpSendRequestExA (on line 639 in the http client above) throws a exception after a few minutes! (i get error code 12002 ERROR_WINHTTP_TIMEOUT)
The Apache doesn't get a request! in the access.log i only see the first two requests
the flags for the connection are NTERNET_FLAG_HYPERLINK | INTERNET_FLAG_KEEP_CONNECTION | INTERNET_FLAG_NO_UI | INTERNET_FLAG_RESYNCHRONIZE | INTERNET_FLAG_NO_CACHE_WRITE | INTERNET_FLAG_PRAGMA_NOCACHE | INTERNET_FLAG_RELOAD
1. anybody else had similar problems with HttpSendRequestEx (and what solved/caused the problem?)
2. anybody has an idea what's causing the problem
3. solutions/workarounds?
4. i don't know how to analyze the problem, so know what causes the problem
how can i analyze what HttpSendRequestExA does to know what causes the problem?
5. may it helps if anyone explains how to use HttpSendRequestExA (i mean, making a connection, working with the connection, closing the connection (just like a function list/ maybe the connection isn't closed and i don't know which function does this))
thx@ll

i tried the example from the msdn and i get an error 997 Overlapped I/O operation is in progress
the code:
BOOL UploadToURL::Test(TCHAR *upFile){
INTERNET_BUFFERS BufferIn = {0};
DWORD dwBytesRead;
DWORD dwBytesWritten;

BufferIn.dwStructSize = sizeof( INTERNET_BUFFERS );
HINTERNET hRequest = HttpOpenRequest (hConnect, "PUT",
"/upload.php", NULL, NULL, NULL, 0, 0);
if (!hRequest)
{
printf("Failed to open request handle: %lu\n", GetLastError ());
return FALSE;
}
HANDLE hFile = CreateFile (upFile, GENERIC_READ, FILE_SHARE_READ,
NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
if (hFile == INVALID_HANDLE_VALUE)

}

do
{
if (!(bRead = ReadFile (hFile, pBuffer, sizeof(pBuffer),
&dwBytesRead, NULL)))
{
printf ("\nReadFile failed on buffer %lu.",GetLastError());
break;
}
if (!(bRet=InternetWriteFile( hRequest, pBuffer, dwBytesRead,
&dwBytesWritten)))
{
printf ("\nInternetWriteFile failed %lu", GetLastError());
break;
}
sum += dwBytesWritten;
}
while (dwBytesRead == sizeof(pBuffer)) ;
CloseHandle (hFile);
printf ("Actual written bytes: %d\n", sum);
if(!HttpEndRequest(hRequest, NULL, 0, 0))
{
printf( "Error on HttpEndRequest %lu \n", GetLastError());
return FALSE;
}
return TRUE;
}

Hi every one,
Is there any way to send a string to a computer in a local network?
But the network hasn't any configurations.

Or is there any way to send a string to a computer using mac address?

Cheers,
Thanks.
