Hi,
I had the same problem. I wanted (not needed) to change to the new environment,
which was VC7.1 (.Net 2003). At first there where some compile errors because of a stricter
ANSI compiler. Solving these did solve a few not simulatable bugs, so it was a good thing.
BUT a whole bunch of new bugs where introduced although everything compiled.
1. My communication failed. I used CSocket to pass Objects to another program using Serialisation
via CArchive/CSocketFile. While this never was a problem in VC6.0 (the program runned for a few
years without any problems), now the CArchives blew them selves up after a short period of time. I needed to rewrite the full communication protocol which set me back a few weeks.
2. A short while ago a change in the MFC classes caused a new bug. In VC6.0 I can't remember
the use of the smallcaps bool, everywhere the big caps BOOL was used.
But the VC7.1 MFC classes using booth even in the same class. So one function could return a
BOOL while another uses bool. The internal handling of logical operation now uses the smallcaps
bool. This can lead to bugs.
But what the heck, I'm now running in VC7.1 and I need to change to VC8.0
In my opinion yes I need to upgrade to VC8.0 for two reasons VC7.1 is dead  .
It didn't get a change. Theres a new compiler in town.
Microsoft maked it more ANSI C++ compliant forwich we chear.
But the major reason is: if you are forced/brave/dumb enought to write managed code,
you will need this compiler suport for the 2.0 framework.
Finaly I compiled my code with VC8.0 and only a few minor errors did com up all because of the
strictness of the new compiler. So I'm getting ready to move to VC8.0
I dont think that there will be great changes underneath, like doing the complete opposite
of what you programmed to do in VC6.0.
Here is a link[^] to find all new features in VC8.0
Hope that this helps you to upgrade decision,

Hi,
I have a toolbar into which I create an ordinary pushbutton. However, I can't get the button enabled or to send button clicks to the parent window. Does anyone know how to do this?
Thanks,

Handle this message for the button:
ON_UPDATE_COMMAND_UI
And write your enable disable code here. pCmdUI has got the necessary elements for this purpose:
afx_msg void OnUpdateYourButton( CCmdUI* pCmdUI );
<marquee direction="up" height="30" scrolldelay="1" step="1" scrollamount="1" hspace="0" vspace="0">

Hello all, my owner-drawn CListCtrl is having problem on Win2K system, its items are too spaced out only on Windows 2000. This is not happening on Windows XP systems.
Please take a look at the following image: http://psychopotato.com/temporary/clistctrl.png (opens in a new window)
It might be due to the different behaviors of MFC controls on these different operating systems. Will I be able to override this behavior and make them look the same? I have tried to intercept and process LVM_GETITEMRECT and LVM_GETITEMSPACING (I'm deriving a class from CListCtrl) but they did not help. Is there anything else I'm lacking? Thanks in advance for any help!
Regards,
Ben.

I have a VC8 Managed C++ Windows Form project. In it I try to overide thd WndProc like below, but when debugging the function is never called. I'm not sure why, has the method of doing this changed since VC7.1?
void WndProc(System::Windows::Forms::Message MsgByRef)
{
switch (MsgByRef.Msg)
{
case WM_PAINT:
{
PAINTSTRUCT kPS;
HDC hDC = BeginPaint((HWND)MsgByRef.HWnd.ToPointer(),&kPS);
EndPaint((HWND)MsgByRef.HWnd.ToPointer(),&kPS);
}
}
Form::DefWndProc(MsgByRef);
}

I am using a Windows Media Player ActiveX control in my CFormView.
I am having trouble retrieving some of the properties.
This works:
m_cVideoControl.SetProperty(DISPID_WMPCORE_URL, VT_BSTR, m_pDocument->GetPathName());
but this does not (it fails returning VT_EMPTY inside MFC):
void CMyApp::PlayStateChangeVideoControl(long NewState)
{
if (NewState == wmppsPlaying)
{
CString cTime;
m_cVideoControl.GetProperty(DISPID_WMPCONTROLS3_CURRENTPOSITIONTIMECODE,
VT_BSTR, (void *)&cTime);
UpdateData(FALSE);
}
}
All of the examples use VB, javascript, etc and seem to be accessing the
player.controls.currentPositionTimecode
I am unsure as to how to accesing this sub group "controls" using GetProperty
In case you are wondering I am using MFC not ATL and I let BEGIN_EVENTSINK_MAP
handle event sinking for me (which works fine).
thanks for any help...

OK, I figued out what to do.
Basically, I call GetControlUnknown() on my control and from there I can
QueryInterface the other pointers I need.

According the The file "Casting Difference Between C and C++ May Cause C2105"
(please see http://support.microsoft.com/kb/q88434/#appliesto),
We know the following code:
void main()
{
char *p;
((long *)p)++; // If the file is saved as a .CPP, this
}
will be have error C2105 need l-value for c++. but for .c file is ok.
Now I have very some problem (when i try to translate some codeing from
c => c++ ). So how to fix the problem?
func()
{
MIDL_STUB_MESSAGE _StubMsg;
int __RPC_FAR *nCount;
RPC_STATUS _Status;
...
*(( int __RPC_FAR * )_StubMsg.Buffer)++ = *nCount;
...
}
I got erro messsage for "*(( int __RPC_FAR * )_StubMsg.Buffer)++ = *nCount;"
the message is "error C2105: '++' needs l-value"
How to fix the problem?
Thanks!!!

Replace above code with

_StubMsg->Buffer++;<br />

Hello,
I've been tasked with creating an automated build process in a Visual Studio 6.0 environment. This is not something I'm familiar with and I'm hoping some of you may be able to point be to some tools or articles that would help me in this area.
Any and all ideas welcome!
Thanks!
-Ian

By "automated" do you mean without any human intervention? If so, I've compiled from a command prompt in the past and it has worked fine. It required a few .bat and .mak files.

Beyond starting the process, there should be no further human intervention. I'm researching .mak files now. they look like a pain. Do you know of any good resources that I can use to learn about them? I'm just googling now...

it's pretty easy to launch Visual Studio from a command line prompt, with a solution/workspace and build configuration name. ex. here's a bit of what we use for our ImgSource builds, on VC7:
devenv /clean Release /project _isource /projectconfig "Release|Win32" ISource.sln
devenv /build Release /project _isource /projectconfig "Release|Win32" ISource.sln
you need to launch this from the command line prompt that VS creates for you (it sets up a bunch of ENV variables for you). but, there are no makefiles - just create the configutations in the UI as you normally would, then run them from the command line.

Unfortunately I'm stuck with Visual Studio 6 right now. There must be similar support in VS6 though huh?
For now, I think I'll delve deeper in the makefile bussiness - that is, unless you can tell me why I shouldn't...?
Sorry, I'm still trying to grasp the overall architecture of an automated build process. I probably have a few days research to do..
Thanks for your suggestion!

i'm fairly certain VC6 has a similar interface.
in VC6 we can use the "Build All" option from the UI to build our 5 different targets, but VS.Net's dependency checker handles .LIBs differently, so we have to simulate a Build All with a .BAT file.

Makefiles are actually simple once you peel away all of the unnecessary stuff. For example:
myproject.exe : myproject.obj file1.obj file2.obj myproject.res
link.exe /out:myproject.exe myproject.obj file1.obj file2.obj myproject.res
myproject.obj : myproject.cpp
cl.exe /W4 myproject.cpp
file1.obj : file1.cpp
cl.exe /W4 file1.cpp
file2.obj : file2.cpp
cl.exe /W4 file2.cpp
myproject.res : myproject.rc
rc.exe /fo myproject.res myproject.rcsays that myproject.exe depends on myproject.obj, file1.obj, file2.obj, and myproject.res; myproject.exe is created by executing link.exe /out:myproject.exe myproject.obj file1.obj file2.obj myproject.res. Also, myproject.obj depends on myproject.cpp; myproject.obj is created by executing cl.exe /W4 myproject.cpp. The files listed on the right side of ':' are what get compiled or linked together to create the file on the left side of ':'.
Any clearer?
There's also the IDE that can be launched without any human intervention. Check out its command-line arguments.

Again, thanks for taking the time to post such a great response. I really appreciate it.

VC6 has the ability to export .mak files that you can use with nmake.exe (project -> Export Makefile). If you add file or projects to your workspace you simply generate a new .mak file. From there it is simply a matter of writing a .bat file for setting up all the proper nmake options.
Note that I hvae never done this for anything more than simply trying it out. Most of my apps compile very quickly, so I usually just wait for them to compile from the IDE.

That sounds great! I'll look into this right now. Thanks!

You can just build the .dsw file from the command line. Saves the risk of the .mak getting out of step with the main project.
|
|
|
|
|
You don't need extra .mak files, just use a .dsw file from a batch file. We use:
@msdev "components.dsw" /MAKE ALL > BuildComponents.log 2>&1
That's an excerpt from our automated build. Here we have one batch file that
- compiles .mc files
- builds all the projects (the .dsw file above is simply a workspace with all the projects in it)
- parses the build log for errors
- compiles the HTML help
- builds the base InstallShield installations
- builds self-extracting installtions for the web site
- builds the CD-ROM images for CDs
It is a bit of effort automating the whole build process, but believe me, it's well worth it.

Hey
I have an app that needs to be able to connect to the internet at anytime, unattended, day or night. What I have done in the past is called InternetAttemptConnect(). But in order for this to work I had to make sure that I allowed my dialup connection to connect automatically. But thanks to some poorly written apps (Firefox, ZoneAlarm) that option is no longer becoming viable as those apps are also able to connect at any time (and they do). So what I did was change the connection call from InternetAttemptConnect() to InternetAutodial(INTERNET_AUTODIAL_FORCE_UNATTENDED,...) which allows me to clear the automatically connect flag in the dialup dialog and still be able to make the internet connection my app has to make, but stop the other apps from doing the same.
But that has lead to another problem. If the dialup dialog is started by one of the other apps and is waiting for user input, InternetAutodial will also hang, waiting for the same user input.
So what I would like to know is if there is an API or other way of telling if the dialup dialog is already present, and if so how can I kill it so that my call to InternetAutodial() will succeed? I could use FindWindow to look for a dialog with the caption "Dial-up Connection" but to me that just doesn't seem to be a very safe or portable way to it.

Do you know what process owns that dialog?

Agreed.
