Hi
How did you create your object ?
This could help you,
class Base
{
public:
Base(int k)
{
value = k;
}
private :
int value;
};
class Derived:public Base
{
public:
Derived(int k):Base(k)
{
}
private:
char s;
};
int main(int argc, char* argv[])
{
Derived object(10); // and not Derived object; This will give those
return 0; //errors as you mentioned.
}

Thanks for your replies.
I am not sure what I did wrong but after deleting the default constructor it compiles and links without errors. I think my object instantiation was wrong. Unfortunately I did not have VSS running at this time so I cannot backtrack my code. Sorry.
Thanks again.

I need to receive in matrix, the image data of a USB camera. Is there some built in VC++ function or some API/SDK for this purpose.

My program is going to either save, or have access to notepad edited text files that I can rely on to be in a certain format, N rows of header info (in CSV format mainly), and then rows of data. I could include a "datarows=" field in, but think I'd prefer a more elegant way to be able to read past the header (I'll worry about that later), but then be able to just read in a line from the file, check if it's data, and do something with it, but if it's an empty line or end of file, to stop
Not sure how to correctly process .getline properly on my fstream object to do that even though it seems obvious I want
assume file checked for existence
read in (use/dont use) N lines of header
while(some return condition that isn't end of file)
{
get a line - put in CString?
process the line
make sure it was valid data, or end the reading
}
A nudge in the right direction would be appreciated

One possibility:
ifstream in("");
string strLine;
while (getline(in, strLine))
{
}For a more complete, and C++, solution, see here and here.

hello,
I do not want to use LoadFrame in the application class and instead use Create() to create the frame window and set menu afterwards.
But don't know how to proceed.
I want to delete the IDR_MAINFRAME from Menu resource.But if I delete IDR_MAINFRAME from the menu resource I get unhandled exception .

What have you done till now? Posting the code should help.

Hello,
You answered my question last time.But I was not able to create the frame window without removing
if (!pFrame->LoadFrame(IDR_MAINFRAME))
return FALSE;
What I have done is this in the application class's
InitInstance()
if(!CMDIFrameWnd::Create(NULL, "MyFrame",WS_VISIBLE,
CRect(0,0,0,0),NULL, NULL))
pFrame->SetMenu(&mymenu);

Did you try replacing the battery in your wireless mouse?

Turn the mouse over. The battery juice keeps settling to the bottom.
BTW, do you have a Microsoft Laser Mouse 6000?

Yes but I don't want to do it 
It's amazing how long I'll put up with that dialog popping up before I reach all the way over to
the drawer next to me for batteries 
Update: Mouse battery status is now critically low

Hi,
Could u give some pointers on how to create a window that would look like MSN live messenger ? I am referring to those funky adornments and decorations that are found on MSN Live Messenger ? Things like gradients, tiny bitmap buttons, flyout controls - its like they have used HTML rendering for this.
Your help is highly appreciated as I am suppose to give my thoughts on how to create a similar gui for an application.

Something like that would be very complex and would require a lot of drawing functions, and a LOT of owner-drawn controls - you would have to owner draw pretty much everything, which although having a nice end product, is very laborious and time-consuming. Note also that although it looks funky, it does slow the application down significantly, especially if transparency and other complex graphical renderings are used, one of the reasons why I believe that Windows Live Messenger is quite slow :@. You could think about creating simple owner-drawn items, such as buttons and menus, which are relatively simple to do, and then you could have some decorative bitmap images kept in a resource file which could be painted onto the background or something using the WM_PAINT command. You could also use transparency to make the application look more futuristic - take a look at this sourcecode here (Note the copyright notice).
Also, if you are using Visual Studio, take a look at the GDI+ documentation on MSDN for some more information. GDI+ is a good API as it is redistributable, under the copyright notices (look at the legal information on MSDN), and it allows for some basic image manipulation and reading of common file formats such as .jpg, .gif and .png, aswell as some nice text functions.
It also depends whether you want to use classes and MFC or not. I'm sure that there are a lot of classes out there for this sort of stuff, but as a straight-C programmer I am not familiar with any of these.
If you specify what you are trying to aim for further, I may be able to help you out a bit more.
Hope this helps!

Hi,
I am using Visual Studio 2005 and Win 2k3 and I have made a command "del /S /Q /f c:\\testfolder", and want to execute it through CreateProcess, i get the error The system can't find the file specified i.e. "Del" exe, I usually use Del from command prompt, and in command prompt it works fine, any help regarding that.
Warm Regards,

try:
system("del /S /Q /f c:\\testfolder");
