Solution: The casting is wrong. Now I just have to find a way to pass my TCHAR array/string correctly.
g_handle_SharedMemory[i_counter] = CreateFileMapping(
INVALID_HANDLE_VALUE,
&l_securityattributes_AllAccessAttr,
PAGE_READWRITE,
0,
MAX_SH_MEM_SIZE,
"Global\\Shared Memory" );
instead of
g_handle_SharedMemory[i_counter] = CreateFileMapping(
INVALID_HANDLE_VALUE,
&l_securityattributes_AllAccessAttr,
PAGE_READWRITE,
0,
MAX_SH_MEM_SIZE,
(LPTSTR)Somestring );

Hi to all. I have an app for burning optical media using IMAPI2. I'm handeling device changed messge (WM_DEVICECHANGE) so I could track insertion or removal of media in record drive. When media is arrived I try to get type od media wich is inserted (eg. DVD-R). My app reports this error:
"First-chance exception at 0x7c812aeb in MyBurner.exe: 0x8001010D: An outgoing call cannot be made since the application is dispatching an input-synchronous call."
What I'm doing is this:
IDiscFormat2Data->get_CurrentPhysicalMediaType(&mediaType);
Could you please tell me why is this happening and how to fix this? Thanks in advace.

If you're importing a typelib, you get lots of wrapper functions, which fire off exceptions.
I hate this with a passion, and end up using the raw_XXXX versions, which return a nice friendly HRESULT. It may be that windows needs a bit of time after the instertion of the media for it to be useful - so you may want to check a few times, waiting a couple of seconds between each attempt. If you use the non-throwing access function, you get the chance to do this.
No knowledge specifically of IDiscFormat2Data though...
Good luck!
Iain.

Thanks Iain.
You are right I'm using wrap functions in this case (although they also return HRESULT).
And yes I've already tried with 'sleep' function after I get my message of media being inserted in optical drive, but no success there.

Hi,
Can u please tell me how to access records from multiple tables in oracle 10g to a SDI application having database support(VC++),using ODBC to access the dsn.
|
|
|
|
|
Only if you can use the search facility provided here on CP with "ODBC" as the search string.
Some things seem HARD to do, until we know how to do them.

Can you use a JOIN statement?

I can access all data from a single table.But If I want to access selected data from multiple tables then I get an error after executing.
ERROR: ORA-00903: invalid table name
DSN Name: om_ebridge.
Oracle User Name: SCOTT
Table Names: Transaction_Master,Transporter_Master,Supplier_Master,Product_Master.
CString CMyebridgeSet::GetDefaultConnect()
{
return _T("ODBC;DSN=om_ebridge");
}
CString CMyebridgeSet::GetDefaultSQL()
{
//return _T("[SCOTT].[TRANSACTION_MASTER]");(works to access data from single table.)
(But ERROR occurs if the below mentioned INNER JOIN is used to access selected data from multiple tables .Can you please help me access data).
return _T("SELECT TRANSACTION_MASTER.TRANSACTION_CODE,TRANSACTION_MASTER.VEHICLE_NO,TRANSACTION_MASTER.OPERATING_MODE,")
_T("TRANSPORTER_MASTER.transporter_name,SUPPLIER_MASTER.SUPPLIER_NAME,")
_T("PRODUCT_MASTER.PRODUCT_NAME,TRANSACTION_MASTER.unit,TRANSACTION_MASTER.Gross_Wt,TRANSACTION_MASTER.Gross_WtTime,")

Perhaps you should try a smaller query first until you get the syntax right. After that, add to it.

When i execute this query in oracle's PLSQL> prompt or in toad the the data from respective tables is displayed.
When accessing data from multiple tables on a single form,is necessary to implement parameterized recordset(ODBC).

Did you try my suggestion here?
Albert Einstein once said “The definition of insanity is doing the same thing over and over again and expecting different results.” You must be willing to try all suggestions no matter how off-the-wall they sound. They might be the exact answer to your problem, but they very well may lead to that answer.

I was asking.But, thankfully my problem of access data from multiple tables is solved using the following .
CString CMyebridgeSet::GetDefaultSQL()
{
return _T("[SCOTT].[TRANSACTION_MASTER],[SCOTT].[TRANSPORTER_MASTER],[SCOTT].[SUPPLIER_MASTER],[SCOTT].[PRODUCT_MASTER]");
}
But if I want to ADD Records to database then I get an ERROR saying "Recordset is readonly".
Previously when I was accessing data from a single table adding records was easily possible, I did not get such an error.Can you please help with this issue.
Thanks.

You can't update when multiple tables are involved.

Is there any way by which I can update data in the tables, because adding data to the table is the main purpose.
Thanks.

Yes, update each table separately.

There are dozen's here on CP, and thousands available via a simple Google search. Look at the CRecordset class and its various members, like AddNew(), Edit(), and Update().

If it were me, I'd try the sql out in PL/SQL before I put it into the code. It's much easier to play with that way. Beyond that, I'd make it a stored procedure when I was done.

Hi,
Main window has a tab control that holds two modeless dialogs(Two tab panes is created) and a button-> on clicking this a modal dialog opens.
Issue:
On opening the Modal dialog box (by clicking button) the main window is disabled and also i can't change the tab panes on clicking the tab control -> this is correct as modal dialog box should not allow other controls to work until it is not closed, but if i click on the controls inside the tab pane (modeless dialog which is opened on tab control during initialization) the modal dialog gets disabled and goes behind the tab pane which is creating problem.
Thanks
