Hi all
I have a Bitmap which is drawn over a dialog box. This bitmap is drawn over several buttons so that buttons are not visible. If I change the DPI of screen from 96 to 120 then the dialog box appears big and buttons are properly redrawn with increased size. But the bitmap is not drawn in the centre of the dialog. The code is given below . Please help me !
Bitmap.LoadBitmap(iIdBmp);
hBitmap = (HBITMAP)Bitmap;
GetObject(hBitmap, sizeof(BITMAP), &bm);
HDC hDC = GetDC(hDlg);
HDC hMemDC = CreateCompatibleDC(hDC);
SelectObject(hMemDC, hBitmap);
hRef = GetDlgItem(hDlg, iIdMap);
if(hRef != NULL)
{
POINT ptTopLeft;
POINT ptBottomRight;
GetWindowRect(hRef, &Rect);
ptTopLeft.x=Rect.left;
ptTopLeft.y=Rect.top;
ptBottomRight.x=Rect.right;
ptBottomRight.y=Rect.bottom;
ScreenToClient(hDlg,&ptTopLeft);
ScreenToClient(hDlg,&ptBottomRight);
StretchBlt(hDC, ptTopLeft.x,
ptTopLeft.y,
(long)(Rect.right-Rect.left),
(long)(Rect.bottom-Rect.top),
hMemDC,
0, 0,
bm.bmWidth,
bm.bmHeight,
SRCCOPY);
}
DeleteDC(hMemDC);
ReleaseDC(hDlg, hDC);

Hi,
I am creating an Excel File from my MFC project. In my project, am using CDatabase class to execute SQL statements.
In the below piece of code, database refers CDatabase object, and sSal is a string.
I have created the table name "Pin_List" already. After creating i need to sort the data according to the column named "DUT_PIN". For that, i used the following lines of code.
But still the output data is not sorted. How to do it..? Is there any error in the following..?
sSql = "SELECT NET_NAME,DUT_PIN,TESTER_CHANNEL,TRACE_LENGTH FROM Pin_List ORDER BY 3";
database.ExecuteSQL(sSql);
With Regards,
Sangeetha.

Hi,
Sorry i have typed "ORDER BY 3" instead of "ORDER BY 2". I corrected in this. Still the sorting is not working.
sSql = "SELECT NET_NAME,DUT_PIN,TESTER_CHANNEL,TRACE_LENGTH FROM Pin_List ORDER BY 2";
database.ExecuteSQL(sSql);
With Regards,
Sangeetha.

Hi Sangeetha,
You cannot use CDatabase::ExecuteSQL for SELECT query. It is only for action query like UPDATE, DELETE and INSERT.
You need a CRecordset object to get the result of a SELECT query.
|
|
|
|
|
Hi Ismail,
Can you tell how to use it..?
CRecordset* record;
record = new CRecordset(&database);
record -> m_strSort = "DUT_PIN ASC";
record -> Open(CRecordset::snapshot, "Pin_List");
recset -> Close();
I used the codings above. But error is coming..
With Regards,
Sangeetha.

WhiteSky, the error is coming while the control goes to BuildSelectSQL() function of CRecordset class. While its coming to the ASSERT(m_nFields != 0) line, its showing the Abort, Retry, Cancel message.

Sangeetha.

The above are the coding lines i used to create the excel file.

Hi Whitesky,
Why no reply from you..?
Sangeetha.
|
|
|
|
|
Your error is in this line recset->Open(NULL,NULL,NULL,"'TABLE','SYSTEM TABLE'",CRecordset::snapshot);,right?
|
|
|
|
|
No Whitesky.. That recset instance is of one more derived class's instance.. My error is in the line,
record -> Open(CRecordset::snapshot, "Pin_List");
No problem in creating the excel sheet.. Its getting created.. But when i am trying to sort through the CRecorset's object, i am getting the error, Whitesky.
Thank you a lot for finding out this thread and replying..
Thank you very much.
With Regards,
Sangeetha.

Expecting the reply..

You dont need to say Thank you.I am here for help to people .I run your code and I saw that your problem was in the line that you want to open recset->Open(NULL,...) and this error was on two parameter that needs to a statement sql for example recset->Open(NULL,"Select * from a"); in previous thread you said you got ASSERT(m_nFields != 0) and I checked for it but for this problem did you use of debugger for see error

Whitesky,
We derived the class named CPinList1 from CRecordset and we wrote the function Open(). Thats what i said there is no error in the recset->Open(NULL,NULL,NULL,"'TABLE','SYSTEM TABLE'",CRecordset::snapshot);. And thats why its possible to open an excel file and write the data into it. IF there is an error means, i could not open the excel file. But if i comment that record -> Open() line means, i can open the excel file and see the contents into it.. But the contents wont be in sorted order.. So as to sort that, i wrote the following lines,
CRecordset* record;
record = new CRecordset(&database);
record -> Close();
record -> m_strSort = "DUT_PIN ASC";
record -> Open(CRecordset::snapshot, "Pin_List");
UpdateData(FALSE);
So i thought the error is from the above lines. I had debugged and seen it.
The thing is the value of the m_nFields is 0. Thats the error.
With Regards,
Sangeetha.

Whitesky, you checked with my post..?
With Regards,
Sangeetha.

Have you seen my, reply whitesky..?
With Regards,
Sangeetha.
|
|
|
|
|
Yes I saw you can open database but your problem is on sort did you use of debugger for see detaily
|
|
|
|
|
Yes WhiteSky, i used the debugger and saw detaily.. When the control comes to the line, record -> Open(CRecordset::snapshot, "Pin_List"); it goes into the CRecordset::Open function and when it reaches the line BuildSQL() line it goes into that function, and then when it reaches the line BuildSelectSQL() line it goes into it . In that BuildSelectSQL() function, there is a line ASSERT(m_nFields!=0); When the control reaches this line, it displaying the Abort message box.. Its telling that the error is in the file dbCore.cpp and in the line 3282. You please analyse this. Or please suggest me some other way, WhiteSky.. Thank You.
With Regards,
Sangeetha.

That assertion error is happening since the m_nFields value is 0. The excel sheet have been created already. I didnt know how come the no of fields value equals zero.

Sangeetha.
