How to set OnFieldchangedLIPadd function to dynamically created ip Address control.

IP address control is created by,

m_cTab.CreateIPEdit(" ", 10, 0, P_LEFT | P_TOP, 130, 0, 130);\

This control is placed inside the tab control.

How to do this?

Is any way to change the value in the second IP address control when tab is leave from first one.

Both are created Dynamically.

Hello all,

When I migrated from visual studio 6.0 to visual studio 8.0 and compiled my project which was built in visual studio 6.0, I got following errors. Can you tell me what might be the problem.

Add wsock32.lib to the libraries that are linked into your project.

Phil

I have already included the include file and the lib file in the project. Then also it is showing this error.

Can you please tell me why ?

I have just migrated from VIsual studio 6.0 to visual studio 8.0 that's why this problems are coming in manier projects.

Thanks for prompt reply.

Hi All,

I have just migrated from VS 6.0 to VS 8.0. Now I want to include some windows files like winsock2.h. I dont know how to do it in VS 8.0 . I searched the toolbar, but didnt get it. Can anyone tell me.

Thanks for prompt reply

Dhaval

LPCTSTR lpszPathName;
CFileDialog fileDlg(TRUE);
fileDlg.m_ofn.lpstrTitle="Open";
fileDlg.m_ofn.lpstrFilter="BMP Files(*.bmp)\0*.bmp\0\0";
if(fileDlg.DoModal()==IDOK)
lpszPathName=fileDlg.GetPathName();
else
return;

CFile file;
if (!file.Open(lpszPathName, CFile::modeRead | CFile::shareDenyWrite))
{
AfxMessageBox("File open failed");
return;
}

Is there something wrong in the codes up?
Thankks~

The messagebox appears~

Did you use of debugger for see value of lpszPathName is it correct and valid?

WhiteSky

I want to open a file named "aa" in path C:\Documents and Settings\示例图片\aa

I saw the debugger and the content is "C:\Documents and Settings\示例图片\葺葺葺葺葺葺葺葺葺葺葺葺?"

Why~?

Here is an example of opening a file open dialog box - hope this helps

void CFileProc1Dlg::OnOpenBtn()
{
// TODO: Add your control notification handler code here
this->UpdateData();

CFile f;

char strFilter[] = { "Files (*.dat)|*.dat|All Files (*.*)|*.*||" };

CFileDialog FileDlg(TRUE, ".dat", NULL, 0, strFilter);

if( FileDlg.DoModal() == IDOK )
{
if( f.Open(FileDlg.GetFileName(), CFile::modeRead) == FALSE )
return;
CArchive ar(&f, CArchive::load);

ar >> m_sample;
ar.Close();
}
else
return;

f.Close();
this->UpdateData(FALSE);
}

I have created a mesh_model.x file that is just the texture and material-

I been looking for an example of animating a mesh- the 3d model is a woman and I know I need to add a bone structure and attatch it to the mesh...

any ideas on how to do this - most books on 3d I have read leave this part out.. I guesing for good reason...

can you sugest a web page or a good book on how to do this?

or an example?

thanks in advance..

Hi,

Do any of you know how to make a progress dialog? I am writing out my data in my CDocument class. I have a menu and a toolbar icon called "process and write out data". I want the progress dialog to update the progress ctrl as work is finished. I was hoping that the right way to do this is to manage the progress dialog updates in my cdocument, since that is where all my data is. Can you give me a little pseudocode that explains how this would work? Or should I be doing it another way?

Thanks,

Max

Most peoples gut reaction to progress bars is something like this...

m_wndProgress.SetRange32(0,500);
m_wndProgress.SetPos(0);

for (int i=0;i<500;++i) {

Sleep(50); // Just to slow this down for demo

/*
do work here
*/

m_wndProgress.SetPos(i);
}

However, if you drop this code into a button click handler in a dialog with a progress bar, you'll notice the dialog becomes unresponsive to any user actions such as closing the dialog.

If processing your work takes enough time to require a progress bar, then it probably should allow the user to cancel or abort the activity. The easiest way to perform some lengthy processing while leaving the GUI thread free to respond to the user is to perform the processing in a separate worker thread. The worker thread then can post messages to the GUI thread to allow it to update the progress bar. This allows the GUI's message loop to process in a normal fashion. When we had the GUI thread performing the work as in the snippet above, message processing for the dialog had to wait for the loop to finish. Unresponsive GUI's are a good recipe for short tempers.

Look up AfxBeginThread() for MFC threading

Not quite pseudocode but I hope it helps get the wheels turning.

I'm incerting the OnKeyDown function to catch keyboard events.. Problem is it never makes it to the function..

void MyDlg::OnKeyDown( UINT nChar, UINT nRepCnt, UINT nFlags )
{
AfxMessageBox(L"Got a key stroke"); <-- never pops up
CDialog::OnKeyDown( nChar, nRepCnt, nFlags );
return;
}

I've got an OnMouseWheel funtion in that works perfectly.. So I have OnKeyDown set in the same way.. Any Ideas?

Do you have a WM_KEYDOWN entry in the window class' message map?

The WM_KEYDOWN will go to the window with keyboard focus. In a dialog this may be one of the
controls in the dialog.

yes I have ON_WM_KEYDOWN() in the message map..
hmmmm.. the function is just not hitting..
