Hey People,

I am finding using VC6 under Virtual PC to be very painful esp. when designing a dialog? Other Apps respond fine. Any Suggestions? I am running the latest VPC, XP, etc.

Thanks,

Davy

I suggest using RDP to access the virtual machine instead of using the 'normal' console. a RDP session is much more responsive.

I'm currently processing a very large binary file in which I need to move backwards and forwards through the file to check for start and end markers, once I've found a matching start and end marker I then go back to the end of the start marker and read in all of the data upto (and including) the end marker.

However I've found that when I use:
seekg ( -1, ios::cur )

it appears to stay on the current element, so I have to do
seekg ( -2, ios::cur ).

Is this correct behaviour? (btw I'm using -1 and -2 only as example values).

many thanks,
Andy

It's not staying on the same element.

Take an example, you have this text in a file: "Test". At the begining, the "file pointer" points before the letter 'T', then if you read this character, the file pointer will point just before the letter 'e'. Thus, if you do: seekg ( -1, ios::cur ), it will rewind one character and thus pointing before 'T', that is the letter you just read. So, as you can see it is not staying on the same element ! Because if didn't use the seekg ( -1, ios::cur ), you would have read the 'e' letter instead of 'T'.

Is it a little clearer ?

Background Color

I'm using the CHOOSECOLOR to change the background color on a hEdit = CreateWindowEx(WS_EX_CLIENTEDGE, "EDIT",.....
control window.
However there is only the background on the main window that changes
hwnd = CreateWindowEx(WS_EX_CLIENTEDGE,MainWindow,.....

Part of the code
SetClassLong(hwnd, GCL_HBRBACKGROUND, (LONG)hbrush);
InvalidateRgn(hwnd, NULL, TRUE);

What's wrong?
Is it possible to edit the bg color on the hedit window?

Yes, You have to handle WM_CTLCOLOREDIT Message in your WndProc!

If you just want to display Picture you can use IPicture Interface to display picture.

here is some link dealing with it:-

Please be carrefull when you copy the examples ! In general the error messages are there to help you. If they say there is an error at line 6, in general it's because there is an error on line 6. And if they say something like

error C2059: syntax error : '.'<br />
Error executing cl.exe.<br />

maybe it's because there is a '.' somewhere where it shouldn't.

So replace the line by:

int main(int arg, char* pszArgs[])

and this should work

That is because you created your project as a Win32 application so the linker looks for the WinMain function to start the code... and of course it cannot find it because you use the main entry point instead. So, go in the project settings and the must be somewhere there an option to change the project type. Select it as a console application.

Or restart a new project and at the begining, be carrefull to choose console application. Then add your file to the new project.

Hope this helps
