Whenever the thump of the HScroll goes to the end of the scroll bar in the CListCtrl, I will add the 20 records in the listctrl. It will be attain by inserting the record at the HScroll method, by calculating the thump value. Whether the thump is getting to the end, then only I will add the records. But I met the problem which is When I track the thump to the end of the HScroll, the mouse holding the Thump. At the time I need to release the mouse from the holding of thump. I have tried by posting the message of WM_LBUTTONUP by the
SendMessage(WM_LBUTTONUP);
function. Please help me..

If you need to release the mouse capture and stop scrolling, I think you can try this sequence:
SetCapture();
ReleaseCapture();
I hope it helps.

Hi Everyone.... i am trying to get this piece of code working over a WAN connection, when i use it on a LAN it works ok.. but when i use it on a wan i can create the connection etc, create and remove directories etc, but as soon as i try to use the openfile function it crashes, does anyone have any ideas why ??
oh, i have tried to use passive rather than Active mode, when i do this i cant use the FtpFindFile function ??
just wondered if anyone had any pointers....
this is the snippet of code..
<br />
CInternetSession oISession(AfxGetAppName());<br />
CFtpConnection* poFtpConnection;<br />
<br />
poFtpConnection = oISession.GetFtpConnection(csSite,"xxx","xxxxx",2001,FALSE);<br />
<br />
poFtpConnection->GetCurrentDirectory(csCurDir);<br />
<br />
poFtpConnection->CreateDirectory(csDir);<br />
poFtpConnection->SetCurrentDirectory(csCurDir + csDir);<br />
<br />
CInternetFile* pInternetFile = poFtpConnection->OpenFile(csFile, GENERIC_WRITE,FTP_TRANSFER_TYPE_BINARY);<br />
<br />
The bold part is where it is falling down...
Any help would be appreciated..
Thanks
Lee

Have you stepped into the OpenFile() method to narrow the problem down further?

yes, it is falling over at the FtpOpenFile method..., the m_hConnection is a valid handle but the hFile that gets returned is NULL ??

When that function fails, what does GetLastError() return?

i have everything in a try catch block, so when it fails its caught and at that point the getlasterror function returns 0 ???? its just baffling me, because it works ok on a lan...

well when i try and call GetErrorMessage i get nothing back, and GetLastError returns 0.... i just cant get my head round whats happening ??? help!!!!!
|
|
|
|
|
little update.... if i change the port to 21 then it works ok... but i need the port to be something different, ie 2001-2009 as there will be more than one client from the router.... anyone got any ideas as to what could be causing it ??
thanks in advance

GetLastError() will only work if it's called right after the function that fails. This is apparently not possible in your case as other functions have been called that have reset the value to 0. However, since you have a try/catch block, you know the exception that is being thrown.

Hi. I want to use text that is not english in the VC6 in some string. I have an English version of VC6 and WIndows XP. I can write in say Chinese or whatever in Word etc because I have the language option set in XP. But in VC, I can not write in anything but English. All other characters come out as ???. Any ideas on who I can do this or if there is anyway for VC6 to support entry of non English char in an English version.
THANKS in advance

I think you need to compile your software application as UNICODE enabled. Should work that way ...

(VC++ 6.0 MFC MDI application)
I'm attempting to add file in use functionality to a MFC MDI application for the life of a CDocument. By default, the CDocument appears to lock the file only during serialization then it releases the file. I need to provide functionality not unlike MS Word where it remains locked during editting.
Just for proof of concept, to just see it work, and later make it a little bit more robust, I was providing implementation for OnOpenDocument, OnSaveDocument, and OnCloseDocument with the original MFC code in them. I made whatever modifications needed to prevent CDocument::ReleaseFile from being called while the file was open and I put a member variable in the CDocument class m_pFile to use to assist in keeping that file locked and open. I'm checking the lpszPathName against GetPathName() to determine when to use the stored pointer versus cleaning it up/closing and getting a new file/pointer.
The files get locked as expected but file Open/Save-SaveAs doesn't modify the file (A temporary file gets created/destroyed during the attempt). Only a New/Save-SaveAs (with a unique name) puts the serialized data into the file. Any ideas or has anyone successfully did this in an MDI app without ripping too much out to do it?

I think you should try a different way. Define a member of CFile type inside your document class, and then override OnOpenDocument, OnSaveDocument, and OnCloseDocument functions. In these functions call the original ones, but also add your code for locking and unlocking the file using additional CFile member (or maybe with some other features).
I suppose the functions may look like this:
BOOL CMyDocument::OnOpenDocument(LPCTSTR lpszPathName)
{
if( ! CDocument::OnOpenDocument(lpszPathName)) return FALSE;
m_MyFile.Open(lpszPathName, CFile::shareExclusive);
return TRUE;
}
void CMyDocument::OnCloseDocument()
{
m_MyFile.Close();
CDocument::OnCloseDocument();
}
BOOL CMyDocument::OnSaveDocument(LPCTSTR lpszPathName)
{
m_MyFile.Close();
if( ! CDocument::OnSaveDocument(lpszPathName)) return FALSE;
m_MyFile.Open(lpszPathName, CFile::shareExclusive);
}
I hope it works.

Thanks. I was overcomplicating the problem. I'll build upon this. Thanks for your help Viorel!
BOOL CFileLockTestDoc::OnOpenDocument(LPCTSTR lpszPathName)
{
if (!CDocument::OnOpenDocument(lpszPathName))
return FALSE;
// TODO: Add your specialized creation code here
// Attempt to lock the file to indicate to others that this file is "in use"
if (m_File.Open(lpszPathName,CFile::modeReadWrite|CFile::shareExclusive)) {
return TRUE;
}
return FALSE;
}
BOOL CFileLockTestDoc::OnSaveDocument(LPCTSTR lpszPathName)
{
// TODO: Add your specialized code here and/or call the base class
if (m_File.m_hFile!=CFile::hFileNull) {
m_File.Close(); // Unlock the file
}
if (!CDocument::OnSaveDocument(lpszPathName)) {
return FALSE;
}
// Attempt to lock the file to indicate to others that this file is "in use"
if (m_File.Open(lpszPathName,CFile::modeReadWrite|CFile::shareExclusive)) {
return TRUE;
}
return FALSE;
}
void CFileLockTestDoc::OnCloseDocument()
{
// TODO: Add your specialized code here and/or call the base class

CDocument::OnCloseDocument();

this is an image/text mixed interface and needs to be preview.
i think 2 ways to do preview (e.g. to 25%):
1) display 1:1 in memory DC then resize to 25% by StretchBlt() to visible DC.
2) draw 25% directly in memory DC or visible DC - if so, how to determine font height and width to exact 25% of original font size?
how do you do for print preview?
thx

Disclaimer: This is not exactly what your asking for but it provides a generic skeleton for your OnDraw stuff so that the view, print, and print preview size themselves dynamically in a fit to width fashion. It uses an arbitrary world space to draw in.
Here's a little to get you started. Start a new MFC/SDI app (CScrollView) and plop this stuff in the appropriate locations. Set up menu/toolbar buttons for the zoomin/zoomout. Add some drawing code to your OnDraw and you should find that the drawing is fit_to_width in the view and it should be fit to width when printing and print preview. The rest is up to you. have fun...
