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 need some help in codding ActiveX container. Short description : Microsoft Visual Studio 2003 and other vsersion (6,7) , includes sample TstCon - a sample of ActiveX Container. When I place control and than delete it or open new document, this program hang up every time when i close it.
I modified ContainerItem method OnDelete()... after pItem->Delete() i put delete(pItem); its all works under win2k... but... in 98SE,XP after deleting control, when i try to insert new control an error occured "Failed to connect.Link may be broken".
So does any one knows how to solve this, and force it to work correctly.
Thanks.

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)
{

return FALSE;
}

printf ("File size is %d\n", BufferIn.dwBufferTotal );
if(!HttpSendRequestEx( hRequest, &BufferIn, NULL, HSR_INITIATE, 0))
{
DWORD d=GetLastError();
printf( "Error on HttpSendRequestEx %lu\n",d);
return FALSE;
}
DWORD sum = 0;
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;
}
but this time i get the error in the first try!

Hi,
Or is there any way to get the IP address of a computer in a local network using the MAC address?
Cheers,
Thanks.

i'm not the network expert, but try to search for RARP (reverse address resolution protocol) maybe you find a rarp client or something

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.
And I have not the computer name or IP address to send.
Or is there any way to send a string to a computer using mac address?
(In VC++ or other labguages?)
Cheers,
Thanks.

how do i sense ctrl+C in a dialog based application?
|
|
|

|

Sorry Heman!
RegisterHotKey function never register Hotkey for Ctrl+c as it is previously register by window for system wide Clipboard usage!

If your just looking to handle the Ctrl-C key while your dialog is in focus, you can easily add an accelerator key.
In the resource view locate the Accelerator folder.
Double click to open it, right click and scroll down to “New Accelerator”

I have a question on setting the application window size. I'm trying to do something non-standard. I want to increase the size of an application's window to be greater than the desktop size. I've tried to use the Cwnd class functions (SetWindowPos and MoveWindow), but none of them allow me to increase the size beyond the desktop's window size. I can increase any application's window size; just not bigger than the desktop. Is there a way around this? Can I use the graphics interface to get around this; or would it just create a stretched image with no real application functionality?

I get the application window's Cwnd handle. Then, I do something like this:
pWnd->GetWindowRect(&Rect);
pWnd->SetWindowPos(pWnd, 0, 0, Rect.right + size_inc, Rect.bottom +size_inc, SWP_NOZORDER | SWP_SHOWWINDOW);
It will increase the size of the app window. At a certain point size_inc does not matter.
|
|
|
|
|
try this
<br />
::SetWindowPos(this->m_hWnd,HWND_TOP,0,0,850,650,SWP_SHOWWINDOW);
