Hi.
Where should I add the functions SetColumnInfo() such that when the program starts up it will remember the size of each pane? Do I need to override a function and add SetColumnInfo()?
You including "splitx." What is that for?
Thanks,
Kuphryn

I'm assuming you do have the msdn help installed? Do an index search for SetColumnInfo().
splitx is the width of the slitter pane i want to start off with.

Here is the solution in RestoreWindowState() functon.
A special thanks to members of CodeGuru and CodeProject for responding about function SetColumnInfo() and RecalcLayout().
-----
bool CMainFrame::RestoreWindowState()
{
m_bVeriReturn = false;
CString version = _T("1.0");
WINDOWPLACEMENT wp;
wp.length = sizeof(WINDOWPLACEMENT);
GetWindowPlacement(&wp);
if (((wp.flags = theApp.GetProfileInt(version, _T("flag"), -1)) != -1) &&
((wp.showCmd = theApp.GetProfileInt(version, _T("command"), -1)) != -1) &&
((wp.rcNormalPosition.bottom = theApp.GetProfileInt(version, _T("bottom"), -1)) != -1) &&
((wp.rcNormalPosition.left = theApp.GetProfileInt(version, _T("left"), -1)) != -1) &&
((wp.rcNormalPosition.right = theApp.GetProfileInt(version, _T("right"), -1)) != -1) &&
((wp.rcNormalPosition.top = theApp.GetProfileInt(version, _T("top"), -1)) != -1))
{
wp.rcNormalPosition.left = min(wp.rcNormalPosition.left,
::GetSystemMetrics(SM_CXSCREEN) - ::GetSystemMetrics(SM_CXICON));
wp.rcNormalPosition.top = min(wp.rcNormalPosition.top,
::GetSystemMetrics(SM_CYSCREEN) - ::GetSystemMetrics(SM_CYICON));
SetWindowPlacement(&wp);
m_nSplitSize = theApp.GetProfileInt(version, _T("topsplit"), 300);
m_wndSplitter.SetRowInfo(0, m_nSplitSize, 10);
m_wndSplitter.RecalcLayout();
m_bVeriReturn = true;
}
return m_bVeriReturn;
}

I have been getting access violations lately. To fix it all I have to do is delete all the object files in the Debug\ directory and recompile. After doing this everything works fine. My question is, Is this normal? Does this happen to other people too or do I have another problem that needs addressing?

From what you're describing your dependencies are out of whack. This is generally solved by doing a Rebuild All (or delete all binaries and Build as you did). However, you need to find out why an incremental build is not building the binaries that need to be built for the app to run. I know this isn't a complete answer, but maybe it will help you in terms of looking in a given direction.

Thanks.
Now that I know it isn't normal I will look into solving it. Just incase it proves to be a hard solution, Is there a problem besides being annoying with the method I have been using?

No. It's just a pain (in terms of time) to have to rebuild all the time. However, it certainly doesn't hurt anything.

Jack this definitely isn't normal. In fact I've never seen anything like this and I work in VC++ a zillion hours a day, every day. It sounds like an out and out problem which is only randomly rearing its head, and doing a clean build makes it *appear* to go away.
Is the violation address consistent? If you are using a lesser version of Windows (not NT,2K,XP), then once something like this happens it can continue to happen until you reboot. Try and run your app under the Debugger at all times, then when you have a problem like this you can step right in and hopefully track it down. It could be a pointer which isn't pointing anywhere valid. If you have exception handling code in your app you should be picking up most if not all problems like this.

Hmmm, so you don't agree with Tom? (see above) Because that was along the lines of what I was thinking.

I agree with Neville. It looks like there may be something awry in your code.

I certainly agree with this, but in my experience VC doesn't get this wrong as long as you've got the project and it's dependencies set up correctly.
If you do a Rebuild All and then it happens again and none of the dependant code has changed, then me thinks it must be a problem in your code.

It only happens if I do a normal build (F7) but is fine after I rebuild all.

I don't know if this really getting anyone anywhere. Why don't you jump into the debugger and track down the exception.

Tom is right in that you're likely run into weird behavior if VC++ doesn't get the dependencies right. And a "rebuild all" forces recompilation of all modules, thereby getting around a bad dependency check.
But I suspect the real problem may lie in the code. I've often run into annoying situations (my fault) when I forget to delete an unused #define from resource.h. It causes no end of problems until I figure out that I'm calling GetDlgItem() with a bogus id. Although the ASSERTs I liberally sprinkle my code with will usually catch that. But annoying all the same.

Very good point, Ravi. That's why while it doesn't hurt anything to do rebuilds, I let him know that it's probably a dependency issue so that he can start looking in that area.

It may be worth checking your clocks date/time and seeing if its set to earlier then some of the .cpp/.h files of your project. This can cause the project to only build partially after a change and link using old .obj files.

Any recommendations for good books on getting started with Managed C++. Preferably aimed at experienced C++ developers.

Hi Michael,
I personally enjoyed very much the MS Press Step By Step book. You do have to wade through a few "this is a variable" type sections. However, I personally don't mind that as I enjoy the tutorial, sequential steps approach as it quickly gets me through the demos of what I need to learn. I will add the caveat that if you've already been doing a lot of MC++, this book will be a waste for you.
I also have the APress book, but I just do not like the format of their books at all.
Cheers,

Hey Tom
This is slightly off-topic. But are there any 3rd party form designer tools for use with MC++?

I'm sure there will be and I've even had friends talk of writing one, but I haven't seen one yet.

If an MC++ form designer comes out I bet I'll prefer that to VS.NET except maybe for MSDN

Thanks, I'll have a look at the MS Press book.
What about the "Visual C++.NET Bible" (assuming you are the same Tom Archer)? What kind of stuff does that cover?

It's me
However, the VC++ .NET bible is named that simply because the product is now affixed with the .NET label whether you use it to write managed extensions or MFC. My book is an MFC book with about 5 chapters on managed extensions, which is why I didn't mention it.

Ok, I'll wait and see what the MS Press one is like first. I might have a look at your book later.
When does the Second Edition of Inside C# get released, Amazon.co.uk is still only listing the first edition
