It can be done.
Try using an Infinite Tee filter to send streams to multiple renderers. It's worth prototyping the exact layout of the filters in GraphEdit to check that everything is going to work before you start coding.

Does anyone know of a function that will take 2 strings and show you the differences between them? Example:
"It takes a big man to cry, but it takes a bigger man to laugh at that man."
compared to
"It takes a large man to cry, but it takes an even larger man to laugh at that man."
would output something like
"It takes a -[big]- man to cry, but it takes -[a bigger]- man to laugh at that man."
I just don't want to reinvent the wheel here if there is something already tested and proven out there.
Thanks,
Jack

How can DSR signal be asserted/deasserted on serial port programmatically using Win32 API's? I know that EscapeCommFunction() can be used to assert/deassert DTR... Does asserting DTR implicitly deassert DSR? Is this how DSR state is toggled?
Thanks,

You can't. DSR and CTS are controlled by the device attached to the COM port. The PC has no control over them at all. You can only control the state of DTR and RTS.

OLE Automation,.. can you give a clue on which component i need to install then ? If i look in the active x addable components, i don't find any "ole automation" component, Just an OleInstall class component..
Thx for the reply by the way! much appreciated..

When I draw text in DirectX using DrawText, capital W's at the left edge of the text have the upper left pixels mysteriously cropped off. Has anyone else encountered this, who knows of a fix? I'm at Wit's End.

Is this with ID3DXFont or CD3DFont (or something based on it)? I've seen this problem with ID3DXFont; it seems that when it draws the text using certain fonts, the kerning bumps the W just out of the texture. Try inserting a space before the W maybe?
I'm using a custom derivative of CD3DFont that decouples the font texture from the renderer, and lets me fiddle with the U,V coords for the characters (and "bake in" stuff like drop shadows). It's not as convenient as ID3DXFont and doesn't support Unicode, but it's a lot more flexible for playing with

This will probably be an easy question for most people, but I'm still somewhat new using the visual studios, and I haven't had much luck researching scrollbars. I am not trying to use a scrollbar to control my main dialog, which is what most articles refer to. I am trying to put a scroll bar in the middle of a dialog that will manipulate a separate control. Basically, I don't know how to wire up my scroll bar after I've added it to my dialog, and there isn't an easy way to add a message handler. If this is just a message map solution, could you please show me a small example with your answer? Thanks a ton!! ;)

Handle WM_VSCROLL or WM_HSCROLL, depending on which direction your scroll bar goes. The last parameter has a pointer to the scroll bar that is sending the message.

Any tools out there for simplifying touch screen application development. Specifically, an onscreen keyboard which is "attached" to an existing CEdit control would be great. Otherwise, I'll have to roll my own.
Thanks!

Hi,
When you create a splitter window there are some bars between the views. You can use there bars to redimension the views. Is there a way to hide these bars? So that the views will appear as one single view...
Thanks

Derive your own class from CSplitterWnd, then override the OnDrawSplitter function. Look in winsplitt.cpp to see the original implementation.

Is there an equivalent to .Net's GetCurrentMethod for Visual C++ 6?
|
|
|
|
|
Not easily. C++ doesn't provide reflection type information in the way .NET and Java do, meaning that it is very difficult to determine what method you are in etc. unless you implement an appropriate framework yourself.
The other alternative is to build your application with symbols, and then use the stack walking functions to determine where you are - that's not a particularly nice way of doing it though.

Hiya I have a global variable in my lib called 'end'. I really need to have it there, otherwise I would just take it out. My problem is that I need to get the lenght of my file in bytes, so I use
ReadFile.Seek( 0,CFile::end );
MyFileSize = ReadFile.GetPosition();
But this is giving me a error of "constant: illegal token on right side of '::', because of my global variable named the same.
Is there another way to get the lenght of my file without using CFile::end in MFC??
Thanks.

Wouldn't the CRT function _filelength() be faster?

There are two ways to do that:
1) If you have already opened the file use this:
CFileStatus status;
ReadFile.GetStatus(status);
LONG size = status.m_size;
2) more general way is this:
CFileStatus status;
CFile::GetStatus(_T("myfile.dat"),status);
LONG size = status.m_size;

I'm doing a get text on a drop down box into a CString. I then do a strcpy to a char array so that I can pass this info off to a LPSTR in a cobol DLL.
When I do a GetWindowText on this combo box and then do my strcpy I get an Assertion failed.
So how can I get this info and convert it to a LPSTR with out doing a strcpy. And How do I delete the char array when I'm finished with it?
Thanks

The assertion generally means that the code has detected that you are calling it incorrectly. So:
1) Post the code that is causing the problem.
2) Where is the assertion occurring? Is it in the GetWindowText()? In the strcpy()? Or somewhere in your code?

Okay. Here is some of my code.
CString CSRAgcy;<br />
char shold[4];<br />
<br />
m_CBAgencyList.GetWindowText(CSRAgcy);<br />
strcpy(shold, CSRAgcy);
It errors out when I do the strcpy. If I comment out that line my program works fine.
Thanks

What's probably happening is that your string is longer than 3 characters, and so the assertion is warning you that you are overwriting memory that you shouldn't.
You need to allocate enough memory to hold the entire string:
CString sTmp;
m_CBAgencyList.GetWindowText( sTmp );
char* pszAgency = new char[sTmp.GetLength()+1];
strcpy( pszAgency, sTmp );
// Do something with pszAgency
delete[] pszAgency;
