Your virtual comm port driver may be bugy. A virtual serial port driver that I use is from http://www.eltima.com[^]. It has a 14 day trial period. See your software works using it.

Guys,
I've created a property sheet and insert two pages in it. By default the tabs appear on the top left corner. I like to place tabs at the bottom or on the sides. How can i do this
|
|
|
|
|
You would have to do this 'by hand', using the tab-control. MSDN has a few examples you can find by searching for CTabControl.
Who is 'General Failure'? And why is he reading my harddisk?!?

I am able to connect to a machine using the foll code. Once it is connected , how do I grab some files from that machine and bring them onto my machine? I was not able to go the GetFTPCOnnection MFC route which has GetFile
( since I have the IP address, not the site and was unable to get the name from IP successfully in that the name came back as "NameOfmyMAchine" with no specifics (used gethostbyaddr) and therefore couldnt connect via CIntnetSession code)
. But the socket() approach works and I need to know how to get the files..........
Thanks,
ns

Doesn't passing the string version of the IP address eg "10.0.0.10" work?

Wish it did! With
m_pFtpConnection = InternetSession.GetFtpConnection ("130.109.184.xxx" );
I get back a null pointer, and this is a valid ipp addres (my secondary machine). However if I put in 'ftp.microsoft.com' it does go there and gets me a ->GetFile() happily..........
Help!!
Thanks,
ns.

If you are connecting to the FTP server, then what you need to develop is an FTP client. An FTP client has to adhere to the RFC 959. In short, your application will instruct the FTP server to connect and download the required files for you. Its an ardous job. Think before you leap!!!

I have a CDialog derived class MyDialog. In its OnInitDialog() function, I create 10 controls with their create function (keeping the pointers as members). They are showing well.
Now, when I close the dialog, what do I have to do. Do I need to destroy the controls? Deattach them? Delete their pointers? And where do I have to do all this?
using: [VISUAL STUDIO 6.0 sp5] [WIN98/2]
|

You probably need to override OnPostNCDestroy and there call delete for each of your 10 pointers... that's it!
|
|
|
|
|
I meant override PostNCDestroy...
|
|
|
|
|
1. The window side of the controls will be destroyed for you, so you don't need to do anything like Destroy or Detach, but you will need to delete the MFC objects you created.
2. The best place is probably in PostNcDestroy for the dialog.

hi guys,
I using Microsoft DateTimePicker Control of CDTPicker Class in VC++. i got invalid property value on statement
m_dtdate.SetValue(var);
my code is
CDTPicker m_dtdate;
COleDateTime CurTime;
CurTime = COleDateTime::GetCurrentTime();
VARIANT var;
DATE ddate;
ddate = CurTime;
var.date = ddate;
m_dttime.SetValue(var);
Thanks in advance
|
|
|
|
|
Try this
VARIANT var;
DATE ddate;
ddate = CurTime;
var.vt = VT_DATE; //
var.date = ddate;
m_dttime.SetValue(var);
This should work!!!

Possibly for the same reason that in the room I'm sat in, we have German and French/Portuguese developers, although we're physically located in the United Kingdom...

Hi,
I have got a CDialog instance, and it has a Cancel and an OK button, OnOk works, but if I call OnCancel, or EndDialog(x), I'm getting an error (in runtime:mad). It says this:
Debug Assertion Failed!
file: wincore.cpp
line: 4184
Can this be caused by the fact that I've got another CDialog instance wich calls the DoModal of the one above? Please help me solve this problem!
|
|
|
|
|
Its not possible to figure out what cud be the issue with the above description.
Would like to know from where that dialog created, what happens after the dialog is dismissed, et al.

You can also check the CallStack by running the program in DEBUG mode, and see from where it got to Wincore.cpp
"A robust program is resistant to errors -- it either works correctly, or it does not work at all; whereas a fault tolerant program must actually recover from errors."

OK,
If I simplify the situation the following happes:
diag2 : diag2.DoModal
diag2 : do some work etc...
diag2 : when ready (or user presses cancel) EndDialog()
or
diag2 : when ready (or user presses cancel) OnCancel()
|
|
|
|
|
Is it like this ??
In Dlgdiag2.cpp
CDlgdiag2::OnSomeAction()
{
CDlgdiag2 diag2;
diag2.DoModal();
}
CDlgDiag2::OnCancel()
{
EndDialog();
OR
OnCancel();
}

It is:
CDlgdiag1::OnSomeAction()
{
CDlgdiag2 diag2;
diag2.DoModal();
}
CDlgDiag2::OnCancel()
{
EndDialog();
OR
OnCancel();
}

If you are calling OnCancel(), you are in trouble. It will take you to an infinite loop. So you should be using CDialog::OnCancel()
I know, thats not the problem you are facing. But apart from that, I just can't find anything odd in this piece of code. You can do one thing. As I have suggested earlier put a breakpoint in
CDlgDiag2::OnCancel()
{
EndDialog(); //HERE
}
put another break point in
CDlgdiag1::OnSomeAction()
{
CDlgdiag2 diag2;
diag2.DoModal();
} // HERE
run the program in DEBUG mode( press F5 ), and then press the Cancel button, then you will be in EndDialog fn. press F5 again, then either the control will reach the 2nd break point, or else it will ASSERT. When it ASSERTs, right click anywhere on the toolbar and select the 'CallStack' option. If you are not getting any idea on what it is, just dump it here, so that we can have a look at where its going wrong.
Another thing I noticed is, wincore.cpp has only 3948 lines. How come you got an error in 4198 ?
