uhhhhh
sounds really dumb but ... when you start a new project you don't enable the help option

Open the .dsp file in notepad or Msdev in text mode.
Delete all the help related text. Reload the project.
Works for me.

I think there'll be an .hpj in the Source file folder that can be got rid of. (It lives in the help dir, but shows up under source files).
BTW most help compile probs stem from a bit of hard coding in this help proj file - at the end, there's a MAP section that usually has to be adjusted when you move the proj to a new machine:
[MAP]
#include <C:\Program Files\Microsoft Visual Studio\VC98\MFC\include\afxhelp.hm>
#include <helptest.hm>

I have come across what is, I think, a bug with Visual C++ running under Windows NT4.
Compiler : Visual C++ 6.0 SP5.
Operating System : Windows NT4 Service Pack 6a.
My code has the following structure:
#include statements
using namespace std;
int main()
{
A lot of computations, input & output operations using streams..............
CString file = "c:\\results.txt";
int history = 20;
const int calcPeriodHalfhours = 6;
ofstream outFile1;
outFile1.open(file);
for (calcPeriod = 1; calcPeriod < calcPeriodHalfhours + 1; calcPeriod++)
{
outFile1 << history + calcPeriod; // this is the line that causes the grief.
outFile1 << endl;
}
outFile1.close();
outFile1.clear();
return 0;
}
If I run the Debug Version of this code, everything is works, and the program exits normally.
Under the Release Version (compiled with /O2 /Ob0), the code runs to the end, producing the correct output, but then comes up with
the Application Error "The instruction at "0x00418698" referenced memory at "0x0000000b". The memory could not be "read". This is an unhandled
Access Violation. Memory is not released to the operating system.
If I disable the optimisations (/Od), the code runs fine.
If I change the line:
outFile1 << history + calcPeriod; // this is the line that causes the grief.
to
outFile1 << history; // this is the line that causes the grief.
or to
outFile1 << calcPeriod; // this is the line that causes the grief.
the code runs fine as Release Version (compiled with /O2 /Ob0).
If I declare the "ofstream outFile1" in the global space instead of in the function space, the code runs fine as Release Version (compiled with /O2 /Ob0).
If I run the original code as Release Version (compiled with /O2 /Ob0) under Windows 2000 SP1, the code runs fine.
Has anyone come across somethding like this problem before?
Please let me know.
Thank-you
Doug Murray

Your EXE's base address is 0x00400000, so something in the EXE is likely dereferencing a null pointer (since the error is coming from an attempted read of address 0xB). Step into the operator<< call and see what happens.

I've got a dialog based MFC application I've been working on. It's an MFC app that uses an ATL COM component. The main dialog gathers a decent amount of data for display through the COM object.
Anyway, depending on whether certain data was available for display I either populated (at the time) a Microsoft FlexGrid control or put up a static box that basically said there was no data to view. The way I did this to begin with was by creating both the flexgrid control and static box exactly the same size and shape and overlapping them in the dialog editor and using controling variables to Hide/Show each depending on whether there was data available. This seemed to work fine at first. However, I started having problem with Visual C++ doing compiles and working with SourceSafe. Eventually it got so bad I determined that SourceSafe must have nuked a file. The biggest problem appeared to be with resources so I went to my project directory and took a look at my resource file... and then took a second look. It was 68 MB! I opened and closed it a couple more times and it ballooned to 276 MB!
Something had gone squirrely with DevStudio or something. I actually had to recreate the project resource file from scratch. I don't know exactly how, but adding in that main dialog simply caused the problem to happen again so I imported all the other bitmaps, icons, dialogs, toolbars, etc and redid the main dialog from scratch. Now my resource file is a nice 22KB. Weird. I tracked through Sourcesafe and watched the file size practically double between each checkin and checkout after adding the static box I described earlier on top of the existing grid control.
Any ideas what could have happened there? Visual Studio 6.0, SP5.

No precise answer, but here we fight a running battle with Sourcesafe ( across multiple service packs ) as far as resources are concerned. Things lost, things doubled up, ID's conflicting, we run a post build step now that tells us conflicting ID's so we can go in and fix them.

Me too ran into problems some time back with the source safe... particularly with resource files. It was too bad that we had to do the updations manually during checking in because it simply wouldnt update itself from the local  . Also, it did screwed some part of the resource from nowhere...

What is the easiest way to read and to write Variables to an ACCESS database??
|
|
|
|
|
Try to use OLE DB provider with ADO connection - it`s simpliest, but not fastest 
...
|
|
|
|

Hello, the codegurus around the world.;)
The easiest way to work Access is to use Access Basic.
However, we can't create the stand alone execute file.
So, the next way is to use Visual Basic with ADO since we can create exe files.
If you don't like Visual Basic like me, now try to use Visual C++. 
ADO expands the approach since we can use the same code to Oracle and SQL server.
However, we can't get the benefit of Access database.
So, sometimes we had better use CDaoDatabase, CDaoRecordSet, and the other useful classes
to deal with the benefit of Access database.
If you have a time, try to create the application by the above methods.
So, you can understand which way is best for your requirement.
Last, Access Database can't deal with concurrent access from the users. (not thread safe)
So, we had better use SQL server or Oracle when the many users access the database at the same time like the web based database.
Have a nice day!

Hello,
I tried to run one of my programs on a computer however I got the following error message:
Error Starting Program
The WINSCHEDULER.EXE file is
linked to missing export SHELL32.DLL:SHGetSpecialFolderPathA.
The computer has Windows 95 (4.00.950 b) and Internet Explorer 5.5 (5.50.4134.0600)
Is there anybody who knows or guesses the source of the error?
Thank you for any helps in advance.
Regards.

I think you've got a SHELL32.DLL version earlier than 4.71.
Internet Explorer 5.5 doesn't update the SHELL32.DLL. It's updated only on Windows 95 or NT4 when you you install Internet Explorer 4 with the integrated shell option (aka desktop update).
A clean way of fixing it is to un-install IE 5.5, install IE 4.01 with desktop update and then re-install IE 5.5.

Does anybody know how to easily convert a string from one charset to another.
Thanks in advance. Bill

Hi Bill,
MultiByteToWideChar converts character set to Unicode.
WideCharToMultiByte converts Unicode to arbitrarily character sets.
Hope this helps

Does anyone have an example how to run JavaScript (or other ActiveScript as VBScript, etc.) from VC++? There is a lot of things that should be worked out to do this (the general problem is passing parameters). I need it ASAP and that's why I'm trying to find already working sample.
Any help will be appreciated.
Thanks!

Have a look to the MSSCRIPT.OCX ActiveX control. There're some sparse example in the MSDN Library.
I hope this control can help you.

I've been searching everywhere for a list of valid arguments to pass into a template class, and I can't find anything. I know that you can use "class" and any basic type, such as int, char, bool, etc., but I don't know how to pass in a string, for example.
I would like my template to be defined something like:
template<class t,="" string="" s=""> MyTemplate...
I've tried using "char *", "VARIANT", and "BSTR", but the compiler won't accept any of them.
Any help is greatly appreciated!
Thanks,
Jason

Hello,
I make my propertypages with the resource editor Visual Studio V6.
I create the propertysheet on the stack and I add the property pages.
The font from the property pages Arial 8 pt is however different than the one I have put with the resource editor Courier New 10 Pt. I tried the SetFont(&MyFont) function but my system make assertion failure.
My question is how can I change the font in my property sheets and -pages ? Any hel will be appreciated.

Is there a way for a syntactical equivalent for the (Java-) finally statement?
What is the most elegant way to simulate it without a subroutine?

Hi
there is
__finally
(2 underlines) but it is Microsoft specific - but as we are in the Visual C++ forum
