How to create VS.NET Tabview for different kinds of MDI documents

29-Sep-02 18:13

Can you make a secure download with CHttpSession? One that accepts certificates or allows you to accept it? I tried setting the secure flag but it times out. I assume waiting for a certificate to be accepted. Any thoughts?

In VS.net, when we open a cpp file, header file, resources, even the help pages, they are showing in the same tabpage-like pane. How can I create something similar ?

Any open source controls like it ?

Should I create different multiple document templates for each types of documents ?

Handle Problem

Hi,

In a dialog based application, I need call a function which is located in another class. In order to call this function, i need the handle of the main dialog.

My problem is how to get the handle of the main dialog and transfer it into the function call? (Some lines of example code ?)

By the way, what is the handle of a menu item and how to get/use it?

Thanks in advance!

AfxGetMainWnd() from memory. It will need to be cast to an instance of your dialog.

One solution to updating a parent windows with data from a dialog box is via messaging. Send the parent windows a message. You could send a pointer to the data. A better solution is just to notice the parent window and have it call a function in the dialog box.

Thanks for thr reply!

In fact, my problem is:

I need call the function

void CAspi32Scsi::WriteCD2ImgFile(HWND Handle, CString fileName, int hid, int tid, int lun)
{
.....
}
in the maindlg implementation loop.

so I have

CAspi32Scsi m_scsi; // this is defined in the CMainDlg class.

CMainDlg::OnWriteImgFile()
{
CMainDlg maindlg;
m_scsi.WriteCD2ImgFile(maindlg.m_hWnd, m_fileName, m_cHost, m_cID, m_cLun);
}
where maindlg.m_hWnd is correct or not?

Thanks in advance!

in OnWriteImgFile() ur creating another CMainDlg and accessing its handle, its like from within ur dialog, ur creating another one and getting its handle, i dont think that's what u want!

Forgot to cast it Smile | :)

CMainDlg* pCWnd = (CMainDlg*) AfxGetMainWnd( );

pCWnd.m_hWnd is still ur handle!

CMainDlg::OnWriteImgFile()
{
m_scsi.WriteCD2ImgFile(GetSafeHwnd(), m_fileName, m_cHost, m_cID, m_cLun);
}

Hi,

Thanks for you all!
It finally worked. The best choice may be:

AfxGetMainWnd()->GetSafeHwnd();

Thanks again,

Saving data between DLL calls

To see if we are on the same track,
You have a dialog class and you wish you use a function from the parent class of the dialog?

One solution would be is to pass the parent within the constructor of the dialog class.

Menus
eg)
CMenu mnu;
HMENU hmnu = pWnd->GetMenu( );
mnu.Attach( hmnu );
// Now you can manipulate the window's menu as a CMenu
// object...

Is there a way to save information between function calls when using load library? I can always use a file on the drive, or redefine my function params, just curious.

a global variable in a DLL will persist until your app releases the DLL.

That would be a prob as I release the dll every time I call the function. It is a plugin. Is that the only way?

maybe not the only way, but it's the obvious way Smile | :)

for plugins, i always write the data to a file somewhere (or the registry, depending on my mood).

My next thought is how to know when the app starts as to not save data between sessions. I may have to have the app set a running flag in the registry or something. If there is an easier way then this. Any clues?
