Is it because your ODBC doesn't support some SQL version?
(in MSDN)
The following SQL-92 features are not supported by Microsoft Jet SQL(the one Access ODBC was using usually):
Security statements, such as GRANT and LOCK.
DISTINCT with aggregate function references.

Hi,
My application should do something like this. When I click a menu item, a dialog is displayed and after entering values and clicking OK, the entered values are displayed in the view. I have done so far.
Now after invoking the dialog, filling the values and clicking OK, I need these values to be displayed in a new frame. How do I go about doing this?
With regards
|
|
|
|
|
try this;
add code in onOK()
{
CNewFrame nf;
nf.m_XXX = yourValue;
nf.domodel();
}

This would mean, CNewFrame is a Dialog. I want to have a frame. Is this possible
|
|

I assume here that you have a SDI application, which consists of a frame window with menu and one view.
When you dismiss the dialog, you can get the necessary data values either by accessing them directly using GetDlgItem or by using the DDX system. Now, if you wish to create a new frame window, then you need to derive two new classes: one from CFrameWnd and one from CView. The frame window is created, and when created, it creates one view for itself.
After this, you can write your stuff into the view by using TextOut functions as necessary.
If you are developing an MDI application, you only need to derive a class from CMDIChild. Then create a new child window, specify the MDI frame window as parent, and use TextOut functions to output text into the child window.

I am using an MDI application. But how do I specify the MDI Frame Window as parent. I am not very clear on this part.
Do get back..
WIth regards

You MDI application consists minimally of following classes:
CMDIApp - This is your main application class, it is derived from CWinApp class.
CMDIFrame - This is your application's main window, a MDI Frame window. It is derived from CMDIFrameWnd class.
CMDIChild - This is one of your MDI child windows. They are derived from CMDIChildWnd class.
When you create new MDI child windows, you first construct their representative objects by either adding a static variable or using the new keyword on a pointer. After the object is constructed, you can call it's Create member method. The fifth parameter of Create is of type CMDIFrameWnd*. This is the address of the class, which is to be the parent of this newly created window. The framework uses this pointer to determine the associated window object and actually specify it as the parent, but we only need to pass the wrapper class's address.
Now, when you create new child windows, you usually call the Create member method from inside a function belonging to the CMDIFrame class, such as OnCreate or OnCreateClient. As you are calling from inside the class's context, the this pointer points to the calling object. Logically, you pass the this pointer as the fifth parameter to specify the calling object (and indirectly the associated window object) as the parent of the new MDI child window.
If you are not creating the child window from inside the context of the frame window class, then you can use the pMainWnd pointer, residing the in the application object, to refer to the main window of your application. This is usually the frame window. Naturally there are alternative methods, and many of them, such as using the extern keyword. What method you use is up to you.
Hope this will be helpful,

Use Constructor to pass the values
x = something * u*;
y= something....;
.
.
.
CNewDialog myDlg(int x, int y,....);
------------------------------------------------
when you create new object this value will be in your constructor and you can access this values!!!

hi, below is my on draw...
it works fine as below...
code:
--------------------------------------------------------------------------------
void CEditorView::OnDraw(CDC* dc)
{
CMemDC pDC(dc);
OnPrepareDC(pDC);
CEditorDoc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
// TODO: add draw code for native data here - use pDC
//as the device context to draw to
//
//Set the mapping mode to LOENGLISH
//
pDC->SetMapMode(MM_LOENGLISH);
//
//Convert arguments to coordinates to MM_LOENGLISH units.
//
CSize szTemp;
szTemp.cx = pDoc->GetGridX();
szTemp.cy = pDoc->GetGridY();
pDC->DPtoLP(&szTemp);
//
// then draw the grid lines
//
CRect clipBoxRect;
pDC->GetClipBox(&clipBoxRect);
for(int x = 10 ; x <= pDoc->GetGridX() ; x += 10) {
pDC->MoveTo(x, -10);
pDC->LineTo(x, -pDoc->GetGridY());
}
for(int y = -10 ; y >= -pDoc->GetGridY() ; y -=10) {
pDC->MoveTo(10, y);
pDC->LineTo(pDoc->GetGridX(), y);
}
}--------------------------------------------------------------------------------
it works perfectly fine as below....
now the problem is i wanan add this to my above code
code:
--------------------------------------------------------------------------------
//
//Draw the squares
//
/*for(int i = 0 ; i < 500 ; i ++) {
for(int j = 0 ; j < 750 ; j ++) {
COLORREF color = pDoc->GetSquareColor(i, j);
CBrush brush(color);
int x1 = (j * 10) + 10;
int y1 = (i * -10) - 10;
int x2 = x1 + 10;
int y2 = y1 - 10;
CRect rect(x1, y1, x2, y2);
pDC->FillRect(rect, &brush);
}
}*/--------------------------------------------------------------------------------
when i do this...
all the processing power of the processor is eaten up by the processor....
can someone pls tell me a solution by which i can incorporate the above code to my View's OnDraw such that i can still retain my processing power????
tks a lot...
Have a Super Blessed Day!

It is not advisable to have a lenghty operation like yours within the UI thread because it gets blocked.
Look up worker threads in MSDN.

index=m_DBName.GetCurSel();
//if i input "sdfs",the next cause a error
str=m_DBName.GetCurrentText();

no ,GetLBText() can't,i have try,
my porpuse:
get the user input not the user select
|
|
|
|
|
GetWindowText
Happy Gemini
|
|
|
|
|
hi,no,GetWindowText is diseable in CComboBox
|
|
|
|
|
What are you talking about ????? GetWindowText is inherited from the parent CWnd class! So that works !!
Just use this syntax:
CString Buffer;<br />
GetDLGItem(IDC_YOURCOMBO)->GetWindowText(Buffer);
(or use m_YourCombo.GetWindowText(Buffer) if it is a member variable of your class).
And that will work !!

I posted a thread about how to detect cdrw and MO,but it didn't get appropriate answer.I just use the way as showed below to do it.
/****************************************************
BOOL GetDriveGeometry(HANDLE hDevice, PGET_MEDIA_TYPES pMediaTypes)
{
DWORD dwOutBytes;
BOOL bResult;
bResult = ::DeviceIoControl(hDevice,
IOCTL_STORAGE_GET_MEDIA_TYPES_EX,
NULL, 0,
pMediaTypes, MEDIA_INFO_SIZE,
&dwOutBytes,
(LPOVERLAPPED)NULL);
return bResult;
}
*****************************************************
I can get all CD driver(including cdrom and cdrw,but just as CD driver) with GetDriveProperty.The reason why I get cdrw as CD driver because their value of
"pMediaTypes->MediaInfo[0].DeviceSpecific.DiskInfo.MediaType" all is "CD_ROM".
I want to know the driver's r/w attribute by its parameter of
"pMediaTypes->MediaInfo[0].DeviceSpecific.DiskInfo.MediaCharacteristics" ,but result is still "read only".
please give me some suggestion.
thank you.

hi,
i m writing a code to enumerate network & local printer in win98 client m/c, the printer driver is installed in my own win 98 client m/c. the same driver is installed in server where the printer is connected.i want to get the printer from the server(network printer or remote printer)....
here is some bit of code to enumerate...
the network printer attribute should be 16 but i m getting 84 value ... WHY ???. sometime i m getting 1108 value for the same network printer....??
code ....---->>
void PrinterRpt9x()
{
BOOL ret1;
printersetting=true;
DWORD i;
PRINTER_INFO_5* pPrint=NULL;
DWORD pcbNeeded=0,pcReturned=0;
HPRINTMUTEX= CreateMutex(NULL,FALSE,NULL);
ret1=EnumPrinters(PRINTER_ENUM_LOCAL,NULL,5,NULL,pcbNeeded,&pcbNeeded,&pcReturned);
//Windows 95: Also enumerates network printers
// because they are installed locally.
pPrint=(PRINTER_INFO_5 *)GlobalAlloc(GPTR,pcbNeeded);
ret1=EnumPrinters(PRINTER_ENUM_LOCAL,NULL,5,(LPBYTE)pPrint,pcbNeeded,&pcbNeeded,&pcReturned);
for(i=1;i<=pcReturned;i++)
{
if(pPrint->Attributes == PRINTER_ATTRIBUTE_NETWORK)
{
_beginthread(printdata9x,0,pPrint->pPrinterName);
}
if(pPrint->Attributes == PRINTER_ATTRIBUTE_LOCAL)
{
_beginthread(printdata9x,0,pPrint->pPrinterName);
pPrint++;
if(pPrint)
GlobalFree(pPrint);
}
}
then i m enumerating the jobs in queue in a thread and creating log file for each print command...
please help in this regard
guide me how to avoid this error ???
in win32 api..

I can get the smtp server address from an email address by using DnsQuery() function.But I wonder wether I can get the pop3 server address or not.
If u can, tell me how. Thanks.
|
|
|
|
|
No, the pop3 server may be on a different machine entirely. Typically ISPs name the machine 'pop.something.com', but thats just an arbitrary naming convention rather than a standard.
