You've not provided nearly enough information. For starters, what code do you have in place to create/display the dialog?

Blew is my code:
CELinkConfiguratorView is the view of my SDI application,Online() is the handler message of a menu, CCBrowseOnline is the class of a model dialog.
when click the menu,the the DlgBrowse dialog should be poped up,but it didn't pop up sometimes .but it poped up after I press the Alt button on the keyboard. why?how to resolve this problem?

void CELinkConfiguratorView::OnOnline()
{
// TODO: Add your command handler code here
CELinkConfiguratorDoc* pDoc = GetDocument();
// Open the serial port

if(pDoc->ComportInfo.ubComInterface == 0)
{
CString msg;
if(!m_Port.Open(ComportNur,
ComportBr, Parity,DataBits,StopBits))
{
msg.Format ("*** Error: Can't open com port");
AfxMessageBox(msg);
return;
}

}

CBrowseOnline DlgBrowse;
DlgBrowse.m_BrowseStr = "Start Browse NetWork...";
if(DlgBrowse.DoModal() == IDOK)
{
isCanSendNew = true;
DownDirect = RST_REQ;
}
}

BOOL CBrowseOnline::OnInitDialog()
{
CDialog::OnInitDialog();
// Inial the progress bar
m_ProCheckOnline.SetRange (0, 63);
m_ProCheckOnline.SetStep (1);
m_ProCheckOnline.SetPos (0);

// start timer
SetTimer(1,100,NULL);
return TRUE; // return TRUE unless you set the focus to a control
// EXCEPTION: OCX Property Pages should return FALSE
}

void CBrowseOnline::OnTimer(UINT nIDEvent)
{
// TODO: Add your message handler code here and/or call default
if(CurrentCtrl == 3) // upload command
{
if(CurrentMacid == 0)
{
str.Format ("Uploading module setting...");
}
else if(CurrentMacid < 63)
str.Format ("Upload Node %d from Scanner",CurrentMacid);
else
str.Format ("Upload completed.");
}
UpdateData(FALSE);
CDialog::OnTimer(nIDEvent);
}

What if you changed the OnOnline() method to:

void CELinkConfiguratorView::OnOnline() 
{
    CBrowseOnline DlgBrowse;
    DlgBrowse.m_BrowseStr = "Start Browse NetWork...";
    if(DlgBrowse.DoModal() == IDOK)
    {
        isCanSendNew = true;
        DownDirect = RST_REQ;
    }
}

Does the dialog appear now?

OnApply()

Hi
I have a propertypage.I have two edit controls.For the first edit control it should have a range of 5 to 50 and for the second it should be 60 to 100.Whenever the entered data was not in this range I gave an error message and set the focus using SetFocus().I have done this in the OnApply() also.
The problem is I have entered the data in the first control and even after receiving the error message and the focus was set also,I have neglected that and entered the data in the second control.For that also I did the same.Finally in the OnApply() also after neglecting the error messages , the dialog has closed.
My requirement is the focus should not go and it has to rise indefinitely if it is not in the range unless I click cancel.Is my approach correct?Please give me a solution.

Thanks in advance.

DeviceIoControl function error

For starters, do not enable the OK or Apply buttons if either of the edit controls have invalid data. That alone will get rid of most, if not all, of your problems.

Hi All,

i am calling DeviceIoControl function to Reset the shared drive device

code snippet is as follows
DWORD dwErrCode, dwErrCode1;
HANDLE hDrive = ::CreateFile("\\\\.\\PHYSICALDRIVE0", GENERIC_READ |
GENERIC_WRITE, FILE_SHARE_READ |
FILE_SHARE_WRITE,
NULL,
OPEN_EXISTING, 0,
NULL );

//check the error in getting teh handle
if (hDrive == INVALID_HANDLE_VALUE)
{
dwErrCode = GetLastError();
return 0;
}
DWORD dwBytesReturned = 0;
STORAGE_BUS_RESET_REQUEST sbRR;
sbRR.PathId = 0;

BOOL bRet = DeviceIoControl
(hDrive,
IOCTL_STORAGE_RESET_BUS,
&sbRR, sizeof(IOCTL_STORAGE_RESET_BUS),
NULL, 0, &dwBytesReturned, NULL);

if(bRet == 0)
dwErrCode1 = GetLastError();

CloseHandle(hDrive);

I am working on windows 2003 server, same code works fine on windows 2000

GetLastError gives "Incorrect Function Error"

can anyone help on this,

Thanks,
Tushar.

I think the fourth parameter to DeviceIOControl() should be sizeof(sbRR).

Could it be that the driver you are trying to reset does not support the specified function?

Hi,

Thanks for the reply,

But the same code works fine on windows 2000 machine for the same hardware.

But does the exact same driver run on both platforms? Chances are that it doesn't, and if that's the case, there could be a slight difference between the two. I'm just grasping at straws here, so my suggestions are somewhat limited.

Hi Programm3r,
Do you want to create the DSN at runtime? or can you create the DSN on a machine and then use it?

Somethings seem HARD to do, until we know how to do them.

David I have tried using that function but I get these error

error C2065: 'SQLConfigDataSource' : undeclared identifier
error C2065: 'ODBC_ADD_SYS_DSN' : undeclared identifier

I have included the following lib's:
- odbc32.lib
- odbccp32.lib

But nothing, what could be wrong?

Thanx
