VC++ 5.0 Upgrade

Not all the features of VC++ 5.0 appear to work with XP and help does not work at all with SP2 without a lot of fiddling. So it seems that MS is trying to push me to purchase new software. VC++ 6.0 is impossible to find, so I may as well go for the latest MS offering. .NET seems to be the route MS wants me to go. I do not want to loose my MFC and C code. In fact I only use C++ for the GUI and C for the donkey work. What alternatives have I got? Any help would be appreciated.

me think it's about time you upgrade ( how old is VC5 ? )

I don't think you will loose your code, at worse, some MFC code was deprecated ( from VC5 to VC 2003 ) and you will need to fix those issues; also there might be a ton of new warnings and compile errors that may appear.

for other alternative, I don't think there are if you need to still work with MFC.

We're in the process of upgrading from VC6 to VC7. The MFC GUI app I work on may not benefit (much) from the upgrade - in fact resource editing promises to be a bit painful in VC7 from what I've heard, although the compiler and STL support is much better.

In any case, you should definitely move from VC5 to VC6 (SP5). As someone else has pointed out, you can buy a copy on EBay. It's also still very much part of the MSDN subscription. VC6 is definitely my favorite IDE.

I can't tell you how bummed I am about having to move to VC7. Frown | :(

Turns out the rest of the product (which is non-GUI) is upgrading their compiler, hence the requirement to standardize.

Hi, I'm another one still using VC++ 5.0 and yes, the online help does not work since installing XP SP2. Can you please elaborate what sort of fiddling is required to make the online help/docu work again ?

Thanks,
Siggy

Tracking mouse position in active view only

Hey

At the moment i'm trying to create an image processing application using MFC (MDI, Doc/View). One of its features is displaying the (pixel) coordinates in the status bar. I managed to handle that by implementing OnMouseMove of the CView class and directly writing to the correct status bar pane, but currently it has 2 flaws. The first one is when the mouse moves out of the client area of the active view, the status bar reports the last updated position. The other is that when you pass the mouse over an inactive view it updates the coordinates for that inactive view. I want to clear the mouse position pane i have created in the status bar when the 2 events described above arise.
I should think this could be solved easily, but i haven't found a solid answer. Can anybody give me some pointers?

Thanks.

For the second point, your view could update the status bar pane when it has the focus only, that is when (GetFocus() == this) (this being the view, of course).

How to draw a graph in MFC?

ATC3-Jan-05 3:15

ATC

3-Jan-05 3:15

I have used VC++ MFC for a while but I have never used with Graph ... because I have never seen a toolbar Control which using Graph!

I think there is a way, anyone can show me briefly how to use it?

1. Which toolbar Control I should use?

2. Let say I would like to draw from x1,y1 to x2,y2 ... what draw I should use?

3. To represent a PIE chart or a PolyGraph, what should I use?

Many thanks

Hi All,

I' m writing a Visual C++ MFC dialog-based program. I tried to show and hide the title bar of a modal dialog dynamically but didn't succeed? Could anyone kindly helps me? Thanks!

Cheers,

Try using this member function of the dialog

<br />
//this will hide the title<br />
ModifyStyle(WS_CAPTION,0);<br />
//then call SetWindowPos() with cx and cy of your own<br />
::SetWindowPos(m_hWnd,HWND_TOP,0,0,cx,cy,SWP_SHOWWINDOW);<br />

to get it back:

<br />
//this will show the title<br />
ModifyStyle(0,WS_CAPTION);<br />
::SetWindowPos(m_hWnd,HWND_TOP,0,0,cx,cy,SWP_SHOWWINDOW);<br />

good luck my friend

Streaming Audio in MFC, C#

I would like to embed a simple streaming audio player similiar to LaunchCast Radio in an application. Where should I start? There are so many different types of methods that I am unsure of the cost/benefits of the different interfaces.

Can someone give me a breakdown of what I would do to start playing a stream from a site?

Languages would be C++/MFC for initial implementation, then later on a new client in C#.

Non Blocking Read through anonymous pipes

pradish mathews3-Jan-05 2:01

3-Jan-05 2:01

I have an application that uses anonymous pipes to communicate with the child process which is altogether a separate application. I was using anonymous pipes in this context but the problem is with the blocking read which leads to the GUI hang. I want to use the same anonymous pipe with Non-blocking read. In unix i was able to do this with select system call but in windows this API seems to be socket specific. Please help.
