Look on the msdn website. The msdn is the microsoft documentation site for windows classes and API, such as CFile.
OK, look at this[^] post. Sorry, had the same idea at the same time.

I want to create virtual drive letters (e.g. X: ) that map to socket connections behind the scenes. I know it is possible because someone has already done something similar to what I want to do:
WebDrive[^]
What should be my approach to this? How does WebDrive do that?

Does this work?

COleDateTimeSpan ts( 10, 0, 0, 0);
COleDateTime dt2 = dt - ts;

hi
I have to do a file conversion which is a very lengthy task.
To show user that the program is converting, I create a modalless dialog with a static text "CONVERTING..." on it. I intend to show it before calling the convert function and hide the dialog after conversion done. code like this:
CDlgInfo *dlg = new CDlgInfo;
dlg->Create(IDD_INFO,this);
dlg->ShowWindow(SW_SHOW);
CallConvertFunction(........sth...)
dlg->ShowWindow(SW_HIDE);
it doesn't work. my dialog show up without the static text on it.
If I replace the convert function call with MessageBox("laksdjlf") then my IDD_INFO dialog shows up with its static text with no proplem. I dont understand why this happen. I have try insert Sleep(1000) or even system("pause") before the convert function call but it also doesn't work.

Probably WM_PAINT messages are not being processed because no window messages are being dispatched
during CallConvertFunction().
What if you force a paint, something like this:
CDlgInfo *dlg = new CDlgInfo;
dlg->Create(IDD_INFO,this);
dlg->ShowWindow(SW_SHOW);
dlg->Invalidate(FALSE);
dlg->UpdateWindow();
CallConvertFunction(........sth...)
dlg->ShowWindow(SW_HIDE);

Thanks a lot. it now runs as I wish
my convert function uses all low level programming techniqe (i wrote it using just C, not C++) and is separated from all windows message. so it was really because of WM_PAINT messages not processed.

Hello friends i am working with database and using "oledb consumer wizard"( provider for sqlserver )for connction with database....But i have a gr8 confusion here...
My table name is "T_Quote"(in .adp)but when i see table name in consumer wizard it is "db.T_Quote"
Can anybody help me to clear me why it is like this way....
|
|

I believe that's the "schema" portion of the table name, where a table name is
server.database.schema.tablename
Similar to namespaces we use in our code.
I'm no SQL expert but if you search "User Schema Separation" you'll find lots of info.
Here's[^] a great board to post the question on.
Hope this helps a little

In Debug mode we can see the debug assertion message, and we cannot run after assertion.
But what happens in release mode.
I saw the entire code after the assertion line in the function is not executed.
But the parent function seems to continue without problem.
Is there any chance for parent function also affected by the error, like function stack corruption etc.
In my case the assertion failure is because of when try to access out of bound index of CArray.
Thanks & Regards,
Suman

In release mode anything in the ASSERT(...) is not compiled, so nothing will happen.
If you put any code in those parenthesis it will NOT be compiled in release mode so it won't
execute.
If you are getting an assertion error during debug then you should fix the error before making
a release build. The release build may appear to run correctly if you don't, but if the assert
was used correctly then it probably shouldn't have been ignored.

That's one you don't want to ignore!

read This[^] and find the "ASSERT and VERIFY" paragraph, around the middle of the page.

Thanks for help.
I would like to know about the effect of assertion failure by MFC library (like accessing out of bounds index of CArray) where there is no ASSERT/VERIFY in code. Does it affect only the function where error happens or the overall application. I am eager to know the answer.
Thanks & Regards,
Suman

Hi, I am trying to set an edit box to read-only during runtime.
I tried the two codes below, both caused the program to close.
m)CEditData.SendMessage(ES_READONLY);
and
m_CEditData.SetReadOnly(TRUE);
How can I toggle the read-only style without crashing?
Thanks

|
|

also, make sure the control's HWND is created befory trying any methods to set the read-only
style.

What happens if you use of ModifyStyle instead SendMessage

Where it takes you in the code if you see callstack during debugging.
There is no harm using these functions, if used this way,
m_ed.Create(WS_CHILD | WS_VISIBLE | WS_TABSTOP | WS_BORDER,
CRect(10, 10, 100, 100), this, 1);
m_ed.SetReadOnly(TRUE);

I've got a problem with a DLL calling a function from a class in the EXE.
Here's the scenario I have. My app needs to give the user the a certain ability if and only if the DLL is present on their machine. (In this case it is a DLL I wrote to print a custom report). So if the DLL exists, when the report is called, the exe passes the object to make the report from to the DLL and the DLL goes to work and make the report.
What I need to be able to do, is to support the object changing in the EXE (new functions, new class members - basically, to be able to change the memory map of the object) and for the DLL (even if it is 3 generations older than the calling EXE) to still take in the object and create the report. This way, the customer can just keep their original custom DLL but still get updates to the product.
Anybody know a way to do this?
Thanks
Dave
