I see your problem. You can't do that with a basic binary tree. You need to switch to an advanced binary tree.

I'm not even sure an advanced tree would work. He might need a segmented octal tree with a U’u root.

It seems simple, in principle: ou have just to reconvert back each byte (two hexadecima digits) of your multiple records and chain them in a single binary file.
What are you afraid about?

You're using ODBC directly? If so, it's fairly easy to do reading/writing of BLOB fields.
These are the only functions needed I believe, most of which you're probably already using if
you're using ODBC:
SQLAllocHandle()
(optional) SQLSetStmtAttr() to set synchronous/asynchronous and other statement attributes
(optional) SQLBindParameter() depending on the query
SQLExecDirect()
SQLFetch()
SQLGetData() / SQLPutData()
(optional) SQLParamData() depending on the query
SQLFreeHandle()

Hi,
Is there any code out there that shows how to make the first colomns of a list control
static. That is when a horizontal scroll is made, the first columns of the control stays
in view. I searched the net for some info, but could not find any.

No, you'll need something like a grid control to do that.

By Design ListCtrl doesn't provide you thsi property but you can achieve same by writing your algo after subclassing the ListControl to make First Item Always Fixed User Scroll. it is pretty much easy if you use GridControl!

What about two CListCtrl overlapped? In the first one the parts that you dont want to loose, in the other the rest. The only problem is you have to keep the CListCtrl scroll sincronized (for the other direction).

I`m trying to create dialog for collecting customer information in an MFC application. The dialog contains a radio button to switch between customer type (private or company) when user changes the customer type I need some controls on the dialog to disapear and others to become visible... What would be your suggestions in getting this done?
|
|
|
|
|
you can make a control invisible by using:
this->GetDlgItem(IDC_XXXXX)->ShowWindow(SW_HIDE);
and visible by:
<br />
this->GetDlgItem(IDC_XXXXX)->ShowWindow(SW_SHOW);
where IDC_XXXXX is the ID of the control.
|
|
|
|
|
Also you can use ON_BN_CLICKED to get notifications when the user clicks a radio button.
In response to the notification(s) you can check if a radio button is "checked" using
CButton::GetCheck() or the BM_GETCHECK message.

Dear all
I add one library file (atapid.lib)to my project and compile it. but I get following error
atapid.lib(tapireq.obj) : fatal error LNK1202:
"D:\...\Debug\vc60.pdb" is missing debugging information for referencing module Error executing link.exe.
How can I overcome to this problem.

Try rebuilding the entire application. i.e. Make a Full Recompile.
vc60.pdb is the 'Program Database' file and will be recreated when you will compile the app.

I am trying to understand how it is possible to transfer a binary file (CFile) through an open CSocket connection that uses CArchive/CSocketFile. Bellow is a sample of my actual code. The socket transfer is working because before transfering the file itself, I am serializing other objects. They are correctly received. But the CFile.serialize() method leads to the reception of an empty file.
Server part :
m_pFile = new CSocketFile(this);
m_pArchiveIn = new CArchive(m_pFile,CArchive::load);
m_pArchiveOut = new CArchive(m_pFile,CArchive::store);
...
CString strFileName = "C:\Toto.exe";
CFile sourceFile;
sourceFile.Open( strFileName, CFile::modeRead | CFile::typeBinary, &fe );
sourceFile.Serialize(*(m_pArchiveOut));
m_pSocket->m_pArchiveOut->Flush();
Client part :
m_pFile = new CSocketFile(this);
m_pArchiveIn = new CArchive(m_pFile,CArchive::load);
m_pArchiveOut = new CArchive(m_pFile,CArchive::store);
...
CString strFileName = "C:\Toto.exe";
CFile destFile;
destFile.Open( strFileName, CFile::modeCreate | CFile::modeWrite | CFile::typeBinary, &fe );
destFile.Serialize(*(m_pArchiveIn));
Any help would be appreciate. Thanks.
Guillaume.

It looks to me (and I could very well be wrong) that you're just serializing a CFile object,
not the contents of the file.
I would think you need to read chunks of bytes from the file and write them to the archive object
instead (read bytes from the archive and write to a file on the receiving end).

Hi Mark
Thanks for your answer.
This anyway sounds strange for me : when I am serializing an object like a CString or a CObList (using the .serialize method), it sends the content of the object. My first thought was that it should be the same for a CFile. What would be the goal of having a CFile object without content ? Strange ...
I will do it myself chunking the file or using the TransferFile API.
Thanks again.
Guillaume.

CFile is just a C++ wrapper around a file handle and provides methods for accessing the file
using the handle. Similar to the way a CWnd wraps an HWND and provides methods to access a window
through that HWND. The actual window data represented by the handle is in the system, not in your
CWnd object.
Hope that makes sense

Hi,
I'm using WinInet APIs in async mode to upload files to server using HTTP protocol and "POST" request. As a matter of fact, I'm trying to simulate HTML form (multipart data) submit button.
I can successfully send file, but I have problem with making progress bar while uploading.
Here is code I'm using for sending:
while (dwReadLength != 0)
{
DWORD dwBytesSent = 0;
dwReadLength = fileLocal.Read(pBuffer, dwChunkLength);
if (dwReadLength != 0)
{
if (!InternetWriteFile(hInternetFile, pBuffer, dwReadLength, &dwBytesWritten))
{
if (::GetLastError() != ERROR_IO_PENDING)
{
strError.Format("CFileHostingHttpUpload::UploadFile::InternetWriteFile(2) = %d",
::GetLastError());
return FALSE;
}
WaitForSingleObject(hAsyncOp, INFINITE);
}
dwTotalRead+=dwBytesWritten;
pbUpload->SetPos(((double)dwTotalRead/dwTotalRequestLength)*100);
}
}
The problem is that my progress bar gets fully "progressed" in about 1-2 seconds, but file uploading is far slower (25kb/s upload speed). When I track transfer with net sniffer tool I can see that it takes about 10 seconds to upload 256 kb file, but progress bar gets fill almost instantly. I've tried about 6-7 different upload "loops" but all of them are giving almost same result.
InternetStatusCallback gives me this:
<br />
11:49:19 - Connected to server.<br />
11:49:19 - Sending request ...<br />
11:49:19 - Request sent: 186 bytes<br />
11:49:19 - Request complete.<br />
11:49:19 - Sending request ...<br />
11:49:19 - Request sent: 86 bytes<br />
11:49:19 - Sending request ...<br />
11:49:19 - Request sent: 4096 bytes<br />
...<br />
... (a lot of same status until the end of upload, no need to paste them all :))<br />
...<br />
11:49:19 - Sending request ...<br />
11:49:19 - Request sent: 4096 bytes<br />
11:49:19 - Sending request ...<br />
11:49:19 - Request sent: 4096 bytes<br />
11:49:19 - Request complete.<br />
11:49:19 - Sending request ...<br />
11:49:19 - Request sent: 802 bytes<br />
11:49:19 - Sending request ...<br />
11:49:19 - Request sent: 16 bytes<br />
11:49:19 - Receiving response ...<br />
11:49:29 - Response received: 1024 bytes<br />
11:49:29 - <br />
11:49:29 - Request complete.<br />
Does anybody have any kind of solution?
Best Regards and have a nice day!
