Hi, I'm fixing someone's code and I came across this:
<br />
BOOL CDatapointSet::Open(UINT nOpenType, LPCTSTR lpszSql, DWORD dwOptions) <br />
{<br />
BOOL rtn;<br />
TRY<br />
{<br />
rtn = CRecordset::Open(nOpenType, lpszSql, dwOptions);<br />
}<br />
CATCH(CException, e)<br />
{<br />
m_DB2 = true;<br />
m_nFields = 30;<br />
rtn = CRecordset::Open(nOpenType, lpszSql, dwOptions);<br />
}<br />
END_CATCH<br />
return rtn;<br />
}<br />
Now, I'm thinking it's a candidate for theDailyWTF; but, I'm not all that familiar with writing database apps as I'm more of an embedded kind of guy.
Is this normal?

What does familiarity with database apps have to do with it? Assigning values to m_DB2 and m_nFields has no bearing on CRecordset::Open()'s ability to open a record set.

This is what I'm screaming!  
That and the fact that the OP(rogrammer) code throws an exception when the first Open is encountered. (The table it's looking for does NOT exist.
Then, in the CATCH block the OP does the exact same thing that caused the exception in the first place without changing a thing.
Like I said, a candidate for theDailyWTF.
I didn't think I was off-base by much. Thanks for your post.

Hello everyone,
I would like to ask if it is possible to use an MFC application as a part of a C# Windows Form project? If yes how is this possible?
Thanks and best regards.

Do you mean using MFC classes in C# project ? Answer is No.

Depends on your definition of "use". If you Wrap the MFC class in a managed class using C++/CLI you could in effect "use" the MFC class from C#.

What does mean "an MFC application as a part of a C# Windows Form project" can you be more specific
|
|
|

Well, what I am trying to do is write some OpenGL with MFC and then wish to use this in a Windows Form as a custom control. It seems weird but I just try to benefit from the MFC performance and .NET Forms usability.

There should be some functions available in AutoCad SDK for sure.
You can get better answers from Autocad forums I guess.

After searched on net, I find One[^] reference. Check ,if it has something to do with your problem.

RTC = RunTime Check
You may need to link to the debug CRT or disable runtime checks.
Look in the online help for RTC compiler option for more details.

Hi
I have this BITMAPINFO and BITMAPHEADERFILE structures
BITMAPINFO *Bitmap = NULL; // lets say that they are initialized corectly and with data in it
BITMAPFILEHEADER bfh;
int Lenght; // the imagize size
char * buff=new char[sizeof(Bitmap)+sizeof(bfh)]; create a buffer
memcpy(buff, &bfh, sizeof(bfh)); // copy bitmap header into it
memcpy(buff+sizeof(bfh), Bitmap, Length); // then copy the bitmapinfo into it and //error
what do i do wrong..
i want to but the bits of those structures into a buffer : thats what he does here:
File.Write(&bfh,sizeof(bfh));
File.Write(Bitmap,Length);
File.Close();
and workd greath..
i assume it similar only that he copies them into HDD
anybody? thanks

One problem I see at first glance is:
char * buff=new char[sizeof(Bitmap)+sizeof(bfh)]; create a buffer sizeof(Bitmap) is going to give 4 bytes, since Bitmap is a pointer.
You need to use
char * buff=new char[length+sizeof(bfh)]; create a buffer just like you have in your memcpy. (This is assuming, of course, that length is properly set before you new the buff.
Hope that helps.

Rather than write buff to the file, why not write bfh and Bitmap directly?

Ok, I misread your initial post. Please disregard my previous question.

This will allocate 18 bytes instead of 58.

Wrong. The two calls to Write() are not putting anything into a buffer. They are writing to a file.
So what exactly are you needing to do with buff?

Hello Comunity,
i make a litle dialog using Create(); , how to set the window style to be always on top,
when the user click somewhere out of this dialog, that they stay on top!?
Like DoModal();?
Some code:
CWaitDlg cWaitDlg;
cWaitDlg.Ceate(CWaitDlg::IDD, GetDesktopWindow());
cWaitDlg.Show(SW_SHOW);
thanks
break;
|
|
|
|
|
Try this call:
cWaitDlg.SetWindowPos(&wndTopMost, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE);
Best,
Jun
