Handle WM_SIZE, the handler for WM_SIZE will have three parameters.
Use the first parameter 'nType' and handle accordingly

I always overrided the cx value with a constant despite what nType is. It's not working. And WM_SIZE is called when the dialog has been fully maximized.

Does WM_MDISETMENU or WM_MDIREFRESHMENU help.

You have tried with:

BOOL SetItemText(
int nItem,
int nSubItem,
LPCTSTR lpszText
);

USB-to-COM problem in WinXP Home Edition

Hi,

I've an MFC application uses USB-to-COM port to communicate with my device. It runs well, both in WinXP Professional Edition and Win2K.

But now, I just found out that, it fails to perform read at one point of stage.

I am reading from the port in chunk of 64 bytes. The ReadFile does not return any error. It just couldn't read anything when it tries to read the 2nd or 3rd chunk of 64 bytes.

Anyone know what's the problem? any solution?

Thanks.

Check GetLastError()

Maybe you have to mark data "as read".

Maybe there isnt anything to read. (Empty)

Thanks for the reply.

The ReadFile does not return any error, but it read 0 byte. However, I am sure my device is sending something over, because in Win2K or WinXP Pro it works perferctly fine.

Any difference in USB-to-COM interface between WinXP Pro and Home edition?

I am worried that when I call ReadFile, the internal buffer has been erased or overwritten. Is there any way that I can check this internal buffer?

First u need to register the OCX.

Follow these steps to register:

1.On the Taskbar, select Start > Run.
2.In the Open field, type regsvr32 "<path>\Strip.OCX", where <path> is the directory where the file is located on your computer and NameOfFile.extension is the name of the file. For example:
regsvr32 "C:\Windows\System32\Strip.OCX"

To insert the registered ActiveX into your current project:

1.Projects->Add to Project->Components and Controls->Registered ActiveX controsl and select that particular ActiveX control.

Hi,
I am trying to run an embeded SQL code using C in the VC++ environment.
I wanted to knw how to bind the DSN with the IP addres so that i can get connected to a remote server.Following is the code: What value should i write for the Data Source?

#include<windows.h>
#include<sqlext.h>
#include<stdio.h>
#include<string.h>
int main(void)
{
HENV hEnv = NULL; // Env Handle from SQLAllocEnv()
HDBC hDBC = NULL; // Connection handle
HSTMT hStmt = NULL;// Statement handle
UCHAR szDSN[SQL_MAX_DSN_LENGTH] = "Provider=SQLOLEDB.1;Persist Security Info=False;Initial Catalog=Northwind;Data Source=10.11.50.15 ";// Data Source Name buffer
UCHAR szUID[10] = "sa";// User ID buffer
UCHAR szPasswd[10] = "mis";// Password buffer

UCHAR szModel[128];// Model buffer
SDWORD cbModel;// Model buffer bytes recieved

char buff[9] = "fgddg";
UCHAR szSqlStr[150]= "INSERT into JON(branch_name, balance)Values ('fgddg',3)" ;

RETCODE retcode;

//sprintf((char*)szSqlStr,"INSERT into (Tablename)(Columname) Values ('%s')",buff);
// Allocate memory for ODBC Environment handle
SQLAllocEnv (&hEnv);

// Allocate memory for the connection handle
SQLAllocConnect (hEnv, &hDBC);

// Connect to the data source "test" using userid and password.
retcode = SQLConnect (hDBC, szDSN, SQL_NTS, szUID, SQL_NTS, szPasswd, SQL_NTS);

if (retcode == SQL_SUCCESS || retcode == SQL_SUCCESS_WITH_INFO)
{
// Allocate memory for the statement handle
retcode = SQLAllocStmt (hDBC, &hStmt);

// Prepare the SQL statement by assigning it to the statement handle
retcode = SQLPrepare (hStmt, szSqlStr, sizeof (szSqlStr));

// Execute the SQL statement handle
retcode = SQLExecute (hStmt);

// Project only column 1 which is the models
SQLBindCol (hStmt, 1, SQL_C_CHAR, szModel, sizeof(szModel), &cbModel);

SQLBindCol (hStmt, 2, SQL_C_FLOAT, szModel, sizeof(szModel), &cbModel);
// Get row of data from the result set defined above in the statement
retcode = SQLFetch (hStmt);

// Free the allocated statement handle
SQLFreeStmt (hStmt, SQL_DROP);

// Disconnect from datasource
SQLDisconnect (hDBC);
}

printf("Done");
// Free the allocated connection handle
SQLFreeConnect (hDBC);

// Free the allocated ODBC environment handle
SQLFreeEnv (hEnv);

return 0;
}

The DSN is what contains the host name or IP address of the machine hosting the database. SQLConnect() should simply be referencing that DSN. It looks as though you might be mixing a DSN and a DSN-less connection.
