I have an activex component that I want to use. The problem is that I don't know how to change the properties of the control dynamically. Is there any way to do this, or are properties purely bound to whatever values I give in the rc editor at compile time?
Thanks for your consideration,
Sean

Most controls will give programmatic access to the properties, although doing so isn't a requirement. This functionality will be exposed through interfaces on the control, typically the IDispatch interface. If you're using MFC's wizards a dispatch driver will be generated to make calling the methods trivial.

When you install a BT dongle, the driver registers one or more virtual COM-ports.
Simply open the virtual COM-port as an ordinary COM-port and you wil be fine.
If you need guidelines for serial programming, have a look here[^].
Hope this helps

I need to develop a software the uses SMBIOS specification. This software must reads/writes the information stored in DMI pool area and must run on MS-DOS. How can I do this using C/C++?

Check out the WMI Win32_BIOS class.

Hello everyone! 
Alright... I formatted my laptop, but now VC++ won't install! It says I was entitled to use it until June 30, 2003, but I've been using it all this time with no problems... I remember last time I installed VC# from the set of CDs (that came with my C# course) first, but now I tried the same thing and it won't work! Anyone know of a workaround to this? Thanks!

Have you tried setting the clock back on your laptop?
(When doing embedded development with pSOS years ago, we had a problem transfering the license for the cross-compiler, so I had to set my computer to November 1998 every time I did development with it.)
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

In case you hadn't noticed, that date passed a while ago... Are you trying to install an expired beta version?

Yeah, it's the Everett beta of November 2002 (which I got in a nylon bag for 99 cents on a thrift store...  ), and yes, it was a while ago, but I was using it all this time without any problems... don't know how I did it last time... But the clock trick is good enough, except for the error message I get about incorrect date before Windows starts...

You missed the point I was making. Maybe I shouldn't be so subtle.
You're entitled to use it until June 30, 2003. It's after that date. Therefore you're not entitled to use it. Simple.

I have two files. For ex: The column1(Name of the column is time) in file1 has the folowing data:10,11,12,13,14,15,17
Column1 in file2 has the following: 10,11,13,14,15,16,17.
Note:16 is missing in file1.
Just ignore the column which is missing in any file and procedd to the others
I need synchronize both the time columns so that they have equal times. How can i handle this?

It almost sounds like you need a merge sort.

Is this what you have, with file1 on the left and file2 on the right:
time time
10 10
11 11
12 13
13 14
14 15
15 16
17 17 Now, what is the output supposed to look like?

output should look like
time

11
13
14
15
17

I've no idea. Both of your input files had seven items each, yet your output only has six items. What happened to 12 and 16?

My output should have only the common items in both the files. Ignore the element which is not present in both the files
|
|
|
|

Ahhh, that is not the same thing as synchronizing. The first thing to do, as I already mentioned, is merge the two files together, thus producing:
10
10
11
11
12
13
13
14
14
15
15
16
17
17
Then you'll want to remove unique items, and then all but one of multiple items.

Dear all;
I am having this weird problem where I am drawing ellipses but they disppear if i resize the dialog box or move the mouse over the shapes.
I know that this problem is related to OnPaint(). Now that i have tried to call Invalidate() and UpdateWindow() after the drawings, I get a blank screen with no drawings. And because the shapes are only drawn whenever I press a specific button, I kind of see the drawings but they quickly disappear.
Here is some code to give u insights:
int CTestDlg::buttonClicked(void)
{
CClientDC dc(this);
drawShapes(dc);
drawings = TRUE;
Invalidate(TRUE);
//UpdateWindow();
}
void CTestDlg::drawShapes(CDC& cd)
{
for(int index = 0; index < 20, index ++ ){
xCentre = getRandom(0, 1000);
yCentre = getRandom(0, 700);
cd.Ellipse(xCentre + 20, yCentre + 17, xCentre - 20, yCentre - 17);
cd.TextOut(xCentre -10, yCentre-10, "A test");
}
// getRandom () is a method which returns a random number
// that is greater than 0 and smaller than 1000 for x and 700 for y
}
void CTestDlg::OnPaint()
{
if (IsIconic())
{
CPaintDC dc(this); // device context for painting
SendMessage(WM_ICONERASEBKGND, reinterpret_cast<wparam>(dc.GetSafeHdc()), 0);
// Center icon in client rectangle
int cxIcon = GetSystemMetrics(SM_CXICON);
int cyIcon = GetSystemMetrics(SM_CYICON);
CRect rect;
GetClientRect(&rect);
int x = (rect.Width() - cxIcon + 1) / 2;
int y = (rect.Height() - cyIcon + 1) / 2;
// Draw the icon
dc.DrawIcon(x, y, m_hIcon);
if(drawings == TRUE){
drawShapes(dc);
}
}
else
{
CDialog::OnPaint();
}
}
Now can someone please tell me whats going wrong with my application ??
Thank you

Tr explicitly setting the pen and brush attributes of the DC - you don't seem to be doing that here and that might be part of the problem. Also try eliminating the "if(drawings == TRUE)" bit just to ensure the function is indeed getting called.

thanx for replying;
Actually, the pen of the dc is already set up, i have just not included it in the my previous posting.
I am sure the drawings are painted because i can see them for a while and then they disappear
Now i tried getting rid of "if(drawings == TRUE)". And it is still not working 
any more suggestions
