No, when I run it I get nothing, just a 1407 error message, and then the program terminates.

Which window??? should it not be NULL like the second messagebox?

Yes, sorry, I was trying something and forgot to replace it with NULL. Still get an error message saying it can't find the window class though. I guess it isn't linking the windows.h file.

I am currently trying to get the return value and output parameters of a stored procedure using ADOs _CommandPtr. As I have researched it should be as simple as the code below:
/////////////////////////////////////////////////////////////////////
_CommandPtr m_pCommand;
_RecordsetPtr rsRecord;
_ParameterPtr pParam;
_variant_t vNull, vValue, vNew;
vNull.vt = VT_ERROR;
vNull.scode = DISP_E_PARAMNOTFOUND;
m_pCommand->ActiveConnection = m_pConnection;
m_pCommand->CommandType = adCmdStoredProc;
m_pCommand->CommandText = _bstr_t("au_info_all");
pParam = m_pCommand->CreateParameter(_bstr_t("@ReturnCode"), adInteger,
adParamReturnValue, sizeof(int), vNew);
m_pCommand->Parameters->Append(pParam);
m_pCommand->Parameters->Append(
m_pCommand->CreateParameter
(
_bstr_t("@au_lname"),
adVarChar,
adParamInput,
40,
_variant_t("Green")
)
);
rsRecord = m_pCommand->Execute(&vNull, &vNull, adCmdStoredProc );
intTest = pParam->GetValue().lVal;
strTest.Format(_T("%d"), intTest);
::MessageBox(NULL, _bstr_t(strTest), _T(""), MB_OK);
///////////////////////////////////////////////////////////////
But the value that I got is always 0. This is not the same case when I use Query Analyzer. Is there anything else that needs to be done?
Thank you.

Having compared your code with the one that I use, it looks perfectly fine,
except that I instantiated an instance of my command pointer before use:
<code>
TESTHR( pCmd.CreateInstance(__uuidof(Command)) );
pCmd->CommandText = _T("sproc_thingy");
pCmd->CommandType = adCmdStoredProc;
..
..
</code>
This my be your problem.

Thanks.
I have seen a solution to it.
In order for output parameters to be retrieved properly, the ActiveConnection's Cursor type should be set to adUseClient
before calling the execute method.
Thank you for the reply. :>

hi,
I place an Edit control on a dialog.
Because it is the first control in the tab order, it gets the focus.
This means that all the text in the edit is selected.
What I want is that the caret is on the last position and no text is selected at all.
CEdit has a member ::SetSel to do this, but when should I call it?
When I call it in the OnInitDialog(), all the text is still selected.
|
|
|
|
|
Hi,
try ON_EN_CHANGE or ON_EN_KILLFOCUS
With Regards,
R.Selvam

|

Right before the OnInitDialog() method returns, post a user-defined message. The handler for that message should call SetSel(0, 0).

I need to route jobs to multiple trays in a printer. One such way that i got to know is to set the default source in the DEVMODE. But even there in the description of the default source, it is given 'Reserved; must be zero.'.
Is there any other way of routing jobs to a particular tray in the printer. This is without displaying the print dialog box. Development environment is VC++ 6.0.
Please help

Humm, dont know the difficulties in Tab Control but i find propertysheet&page very easy to implement and manage.

I have a MFC based dialog application which uses ShellExecute() to launch executables. After calling ShellExecute with for example:
ShellExecute( hwnd,"open",
"C:\\program files\\winamp\\winamp.exe" ,
"c:\\song.mp3",
"c:\\program files\\winamp\\",
SW_SHOWMINNOACTIVE );
I have tried SW_SHOWMINNOACTIVE and SW_MINIMIZE and after the call to launch the executable my dialog application loses focus. I have tried using SetFocus() after the call and nothing I try sets the focus back to the dialog which called the executable.
How do you get the calling application to retain focus after a call to ShellExecute?
Thanks,
Steve

change
ShellExecute( hwnd,"open",
"C:\\program files\\winamp\\winamp.exe" ,
"c:\\song.mp3",
"c:\\program files\\winamp\\",
SW_SHOWMINNOACTIVE );
to
ShellExecute( GetDesktopWindow(),"open",
"C:\\program files\\winamp\\winamp.exe" ,
"c:\\song.mp3",
"c:\\program files\\winamp\\",
SW_SHOWMINNOACTIVE );

I tried your suggestion and it yields the exact same result.
I was about to edit my post but you responded so promptly. Thanks.
My dialog application is using the whole desktop. When I call ShellExecute the task bar comes to the top over the bottom of my application and stays that way until I click on it.
Any other ideas?

|
|
|

well did ya try putting the hwnd to null.
humm well besides this i am out of idea, may be the winamp is tring to put itself up. May be some settings in the winamp itself.
does the same problem accours with other applications??
Well i am sorry, i am out of ideas.

Yes, I tried the putting hwnd to NULL and yes it does it for all executables.
Must be a strange behavior of a dialog based application.
Thanks for your suggestions.

Have you tried using CreateProcess() instead of ShellExecute()?

No I have not but I will try anything at this point.

I have written a program which will accept only 20 connections to the server port. If connection goes beyond 20 then below mentioned code will be executed which is in while loop
memset(cSendBuf,' ',23);
memset(&sd, '\0', 23);
printf("\nRejecting Excess Client %s ...\n",inet_ntoa(sockAddr.sin_addr));
strcpy(sd.cstrmsg,"Rejecting Excess Client");
strcpy(cSendBuf,"");
printf("sd.cstrmsg is ;%s\n",sd.cstrmsg);
memcpy(cSendBuf,sd.cstrmsg,23);
int x=send(sock_id,cSendBuf,23,MSG_NOSIGNAL);
printf("x is %d\n",x);
close(sock_id);
continue;
Problem is socket closes before data is sent to client, so client fails to receive data (even though close is after send). Is there is any way to wait till client receives data and then close the socket or other solution like that. If i put sleep(2); before close then it works fine. Using sleep is not a right way to wait.
Waiting for the reply.

You should create the socket in blocking mode.
|
|
|
|

below is code to create, bind, listen socket.
please tell me where i have to change the code (i am new to socketing).
sockAddr.sin_family=AF_INET;
sockAddr.sin_addr.s_addr=INADDR_ANY;
sockAddr.sin_port=htons(iPortNo);
addrLen=sizeof(struct sockaddr_in);
if((serverSocket=socket(AF_INET,SOCK_STREAM,0))== -1)
{
printf("Failed to create Socket\n");
return -1;
}
else
printf("Socket created successfully\n");
rc = setsockopt(serverSocket, SOL_SOCKET, SO_REUSEADDR,(char *)&optval, sizeof(optval));
if(bind(serverSocket,(struct sockaddr_in*)&sockAddr,sizeof(sockAddr))==-1)
{
printf("Failed to bind at port %d\n",iPortNo);
return -1;
}
else
printf("Binding at port %d done successfully\n",iPortNo);
if(listen(serverSocket,1000) == -1)
{
printf("Failed to listen at port %d\n",iPortNo);
return -1;
}
else
printf("Listening at port %d\n",iPortNo);
while(1)
{
pthread_mutex_init(&tCounter.mutex,NULL);
sock_id = accept(serverSocket,(struct sockaddr_in*)&sockAddr,&addrLen);
..........................
..........................
}
Waiting for the reply

Yes it is a blocking socket. I noticed two potential problem:
1) you use close instead of closesocket.
2) You should set the option SO_LINGER to non-zero, so closesocket will wait for the transmit queue to be empty.
Sorry for the delay in the answer, I am very busy lately.

Hi,
How to insert property sheet into a form view.I am using Embedded VC++. Can u give me some sugg?
Thanks
JP
|
|
|
|
|
I dont know about eVC++, but i would do it this way. Put a static frame on the formview dialog, then in the initialization fot the formview i will create the propertysheet, add the pages to it, get the rectangle are of the static rectangle and move the propertysheet to that rect. Thats it,
also note that the parent of the propertysheet should be the formview window handle.
Hope i solved ur problem in some way.
