Hi,
I'm new to MFC, my question is how to get a pointer to CDocument in a non CView class?
For example in a docking window or a CDialog.

Simpler solution to declare the global Pointer to document class and access that in your Non View Class
|

The best approach is to use something like the following:
CMyFrameWnd *frame = (CMyFrameWnd *)AfxGetMainWnd();
CMyDocument *document = frame->GetActiveDocument();
Software Zen: delete this;

Hi guys,
I am trying to write into xls file. This part is ok.
problem occur while reading from xls file.
error shows as follows :
syntax error in query expression field_2 by demo
code I use for writing into xls file is as follows.
void CWrite_read_xlsDlg::OnButton1()
{
CDatabase database;
CString sDriver = "MICROSOFT EXCEL DRIVER (*.XLS)";
CString sExcelFile = "c:\\kdr.xls";
CString sSql;
TRY
{
sSql.Format("DRIVER={%s};DSN='';FIRSTROWHASNAMES=1;READONLY=FALSE;CREATE_DB=\"%s\";DBQ=%s",
sDriver, sExcelFile, sExcelFile);
// create database i.e excel sheet
if( database.OpenEx(sSql,CDatabase::noOdbcDialog) )
{
// create table structure
sSql = "CREATE TABLE demo (Name TEXT,Address TEXT)";
database.ExecuteSQL(sSql);
// insert data into table i.e excel sheet
sSql = "INSERT INTO demo (Name,Address) VALUES ('Nilesh','Pune')";
database.ExecuteSQL(sSql);
sSql = "INSERT INTO demo (Name,Address) VALUES ('akash','Mumbai')";
database.ExecuteSQL(sSql);
sSql = "INSERT INTO demo (Name,Address) VALUES ('ajit','thane')";
database.ExecuteSQL(sSql);
sSql = "INSERT INTO demo (Name,Address) VALUES ('aaniket','Nashik')";
database.ExecuteSQL(sSql);
}
// close database
database.Close();
}
CATCH_ALL(e)
{
TRACE1("Driver not installed: %s",sDriver);
}
END_CATCH_ALL;
}
code I use for reading data from xls file
void CWrite_read_xlsDlg::OnButton2()
{
CDatabase database;
CString sSql;
CString Name, Address;
CString sDriver;
CString sDsn; // register datasource in ODBC database manager
CString sExcelFile = "c:\\kdr.xls";
m_cList.ResetContent();
sDriver = GetExcelDriver();
if(sDriver.IsEmpty())
{
AfxMessageBox(" No Excel ODBC driver found ");
}
sDsn.Format("ODBC;DRIVER={%s};DSN='';DBQ=%s",sDriver,sExcelFile);
TRY
{
database.Open(NULL,false,false,sDsn);
//A CRecordset object represents a set of records selected from a data source.
//Known as recordsets
CRecordset recset(&database);
sSql = "SELECT field_1,field_2"
"FROM demo "
"ORDER BY field_1";
// sSql = "SELECT * FROM demo";
// sSql = "INSERT INTO demo (Name,Address) VALUES ('Nilesh','Pune')";
//"ORDER BY Name";
recset.Open(CRecordset::forwardOnly,sSql,CRecordset::readOnly);
while(!recset.IsEOF() )
{
recset.GetFieldValue("field_1",Name);
recset.GetFieldValue("field_2",Address);
m_cList.AddString(Name + " --> "+Address );
// m_cList.AddString(Name);
recset.MoveNext();
}
database.Close();
}
CATCH(CDBException, e)
{
AfxMessageBox(" Database error : "+e->m_strError);
}
END_CATCH;
}
call GetExcelDriver().implementation of GetExcelDriver()is written separately.
Read data and dispay is occur when I click on button.
kindly give me a reply where I am wrong.

Hi sasikumarselvarajan ,
Do you want to create eee instead exe?
|
|
|
|

First you don't need an extra application to register a file type.
Second you have already replied to a topic where the answer was given right here[^].
Third do some research before asking for answers.

hello,
can anybody please tell me, how can I make a installer/ setup ( self installing cd) with the executable compiled in VC++ ?The operating system is WINDOWS-2000.

You can use a setup creating program. I use Inno Setup[^].

Inno Setup is great, and so easy to use, I would also recomend this

yeap INNOSETUP is one finest free installer available in market if you are developing a simpler installer, otherwise you have to learn pascal type scripting to make complex installation program using same! just a warning

I have a program that gets a set of 3 messages every second or so.
The message:
- hwnd is NULL (thread message, not window message)
- message is 49338 (0xc0ba)
- LPARAM, WPARAM change for each of the 3 messages
Messages between 0xc000 and 0xffff are string messages generated by RegisterWindowMessage().
I don't call RegisterWindowMessage, which leads me to believe either the debugger or another library (e.g. OpenGL) has created the message.
How can i find who called RegisterWindowMessage to get the message id 0xc0ba ?
And/or, how can i find what string was passed to RegisterWindowMessage ?
...cmk
Save the whales - collect the whole set

I don't think you can reverse the RegisterWindowMessage() function, but if you have Spy++ installed (it's part of the Visual Studio installation, Tools->Spy++) you can use it to find out which application is sending the messages. Run Spy++, use the Find Window dialog to pick your root window, choose the 'show messages' option and then hit OK. A window will pop up showing all the messages your application is receiving, and you can then find the offending messages.
You usually see lines in the Spy++ application that look like:
000D072C S message:0x1065 (User-defined:WM_USER+3173) wParam:00000000 lParam:00000000
000D072C R message:0x1065 (User-defined:WM_USER+3173) lResult:00000000
If you double-click on the 'S' line you'll see information about the sender of the message. Going to the 'Process' tab will then allow you to find out who's sending the message.
In my experience the usual culprits for sending out lots of messages like this are media players which broadcast information about where they are in the song so that third-party plugins can show song information etc.
I know this isn't quite an answer to your original question, but I hope it's useful!
