Hi All,
When database server abruptly goes down, Client hangs in ExecuteSql statement.
I know only the remote(database) port number.
Is there any way to identify the local port that is connected to the remote port and terminate it?
Any help is appreciated.
Thanks in advance.
Regards, Selva

Yes, it can be done by following the instructions in this prior post[^].

Dear All,
I have created a project (dialog based MFC) to display values in the .dat file. I have 4 dialogs and each of the one dialog should display appropriate values parsed from the .dat file. All the parsing methods have been done in a separate class (which is not a dialog).
I call the parsing method (separate class) from first dialog and when I open the second dialog (by a button click event from the first dialog) the values are displaying correctly. After that, if I go back to the first dialog (by a button click event from the second dialog) all the values seems to be disappeared. I am doing something wrong with my code, please help me.
void FirstDlg::OnBnClickedButton1()
{
initvalues();
bool x=process_file();
if(x)
{
MessageBox(L"Processing file succeeded");
}
else
{
MessageBox(L"Processing file failed");
}
}
void FirstDlg::OnBnClickedButton2()
{
OnCancel();
SecondDlg ptr1;
ptr1.DoModal();
DisplayValues();
}
void SecondDlg::OnBnClickedButton1()
{
OnCancel();
FirstDlg ptr1;
ptr1.DoModal();
DisplayValues();
}

it appears that you are not setting the values to be displayed on the first dialog when you do navigate from the second dialog
BTW are you using a property sheet?
Somethings seem HARD to do, until we know how to do them.

I also tried to set the values before displaying the result is the same. Please advice. (I used displayvalues(); before calling the dialog.

if you are using a property sheet you can use the sheet class to store the common information. [it's like a wizard then]
Objects of class CPropertySheet represent property sheets, otherwise known as tab dialog boxes. A property sheet consists of a CPropertySheet object and one or more CPropertyPage objects [As you have screens while installing some software where you do have to click on next/back/finish buttons with some view of the dialogs changing]

You have two FirstDlg::OnBnClickedButton1() methods. Why?
bhanu_8509 wrote: After that, if I go back to the first dialog (by a button click event from the second dialog) all the values seems to be disappeared.
Which would be correct based on what you've shown in SecondDlg::OnBnClickedButton1(). The call to DisplayValues() does not happen until after DoModal() has returned.

I am very sorry David. I have done a typing mistake. I am very sorry. Now I have edited my post.

I understand now that call effect to DisplayValues() will happen after DoModal() has returned. Please tell me how to avoid this. I used Singleton objects using Static members but the same problem presists. Please help me.
Thank you very much for your kind reply.

Having a design such as this is, IMO, a recipe for failure. Why not use a property sheet or tabbed dialog instead?

Sorry David. I cannot understand exactly from your diagram. I am very new to MFC. My requirement is to use Dialogs only, Tabbed dialog and Property sheet should not be used.
Please help me.

I was just implying that having dialog1 call dialog2 which calls dialog1 etc is a bad design. I'm not saying it can't be done, but the solution will be neither straight forward nor elegant.
bhanu_8509 wrote: My requirement is to use Dialogs only, Tabbed dialog and Property sheet should not be used.
Since a tabbed dialog and a property sheet are both dialogs, your requirement makes no sense.

Dear David,
Please help me how to proceed with good design for my requirement.
Many thanks in advance.

Create a dialog with a tab control (CTabControl), or create a property sheet with four property pages.

Hi Friends,
I am getting this error in my program. in Stdafx header file...
fatal error C1083: Cannot open include file: 'afximpl.h': No such file or directory.
But this file is available in C:\Program files\Microsoft Visual Studio.Net 2003\vc7\atlmfc\src\mfc\afximpl.h
So i dont know how to resolve this error.
Could any one try to resolve this.
Thanks and Regards.

how are you including the file? #include <afximpl.h> and before doing that you must #include<afxtempl.h>

To fix by checking the following possible causes:
1. File does not exist.
2. File, subdirectory, or disk is read-only.
3. No access permission for file or directory.
4. Not enough file handles. Close some applications and recompile.
5. The INCLUDE environment variable is set incorrectly.
This is my suggestion. For the Visual Studio please look
under "Tools - Options - Projects an Solutions --> VC++ Directories" for
the include files directories that the Visual Studio uses to search for include files.
There you can add this directory.
6. An #include directive uses double quotation marks around a path specification, which causes the standard directories to be skipped.
7. You did not specify /clr and your program uses CLR constructs.
8. You attempted to compile a single file in the project without first compiling stdafx.cpp. Before you can compile a single file in the project, you need to compile stdafx.cpp. In the case of the /analyze (Enterprise Code Analysis) compiler option, you will need to use the same /analyze setting for stdafx.cpp that you use for the .cpp file.

You shouldn't include this file, it's internal to MFC.

Hi!
I also had this problem.
Just try to include the file using double quotation marks around the path specification:
use #include "afximpl.h" instead of #include <afximpl.h>.

Why? That instructs the preprocessor to look for the file in the same directory as the #include statement, which it obviously is not going to find.

Dear All,
My project requirement is VC++ application need to open an .trp file using FileReading method.I tried it works proper.But i need to open a .trp file using Thead concept...
It will be much helpful to me to give some advice on this..
Thank you very much,
Yours,

Move the FileReading method into the your thread procedure and do things over there.
Since you can open the .trp file it should not be a problem to achieve this from the thread.

Thank you for your kind reply.
If I process the file reading in a thread, the thread starts its separate execution. I need some of the values from the file to proceed further. So please tell me, is it possible to suspend the main thread till the worker thread (File reading method) is completed. Please advice.
