Hello friends:
I want to capture a minimized window in win2000.I search google and many developer use the "printwindow" function to do it.But the problem is that I use win2000 and VC++6. How to do it? I try to copy winspool.dll and user32.dll to win2000 from windowsXP,But it doesn't work 
Please help!

|
|
|
And why it doesnt work?

I don't know.Maybe it use other windowsXP's dll? I copy user32.dll from winxp to win2000 and it don't work too.

PrintWindow is not supported in Win2K.
It is not enough to simply copy some DLLs from XP to make this work in Win2K.
I'm sure the call goes down to the kernel and calls some routines there.
So you will have to implement this the hard way without the PrintWindow function.

I love work. It gives me something to do between weekends.

I have a problem with EAXDirectSoundCreate method call. If I created a DLL which uses MFC, and in the DLL's InitInstance() to revoke EAXDirectSoundCreate. When application runs, and loads the DLL, then EAXDirectSoundCreate executed, application will hang up inside of that method. Need your help here how to fix the problem. Thanks.

How do we build a network using visual c++..The network is assumed as graph.

We usually build networks using cables, hubs, switches,...

I should admit you're more advanced.

No, you must have asked her to search for VC++ in Orkut, FaceBook ,etc. That's what the OP is looking for.

Have a look at the boost graph library. For quidance try ISBN 0-201-72914-8: The boost graph library user guide and reference manual; I recommend it.

Hi,
Has anyone come across a simple way of making an MFC toolbar button flash? I tried using pCmdUI->Enable() with an alternating enable/disable flag which looked great but of course the button is disabled half the time 
TIA
Tony

|
|
How about alternating checked/unchecked?

Hi,
Thanks for the suggestion. I tried it and it looked OK but still not quite what I wanted. For info, I did manage to get the look I was after but I dont know if its the "correct" way to do it. I created two versions of the toolbar bitmap each showing the two states I needed. I loaded them into two image lists in CMainFrame::OnCreate(). I then swapped the image list into the toolbar on a timer, like this...
CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
...
m_il1.Create(IDR_MAINFRAME1, 32, 0,RGB(128,128,128));
m_il2.Create(IDR_MAINFRAME2, 32, 0,RGB(128,128,128));
...
}
CMainFrame::FlashToolbarButton()
{
static bool bSwap = true;
if(bSwap)
{
m_wndToolBar.GetToolBarCtrl().SetImageList(&m_il1);
bSwap = FALSE;
}
else
{
m_wndToolBar.GetToolBarCtrl().SetImageList(&m_il2);
bSwap = TRUE;
}
m_wndToolBar.Invalidate();
}
Probably very ugly - maybe someone else has a more elegant solution.

How about an owner drawn toolbar[^]?

The code below produces the following compiling error:
STS_OP_temp_test.cpp: In constructor 'STS_OP_temp_test<U>::STS_OP_temp_test()':
STS_OP_temp_test.cpp:66: error: expected primary-expression before 'int'
STS_OP_temp_test.cpp:66: error: expected `;' before 'int'
I take the error to mean that the compiler can't resolve "cwtm.templateMethod". Either it doesn't think "cwtm" is defined, or it doesn't think cwtm has a method called "templateMethod".
If you don't quite understand the class template stuff happening here, go to this site:
http://publib.boulder.ibm.com/infocenter/comphelp/v8v101/index.jsp?topic=/com.ibm.xlcpp8a.doc/language/ref/template_template_arguments.htm
But that site doesn't solve my problem.
Thanks for your help.

I've done some more testing and uncovered something interesting. The template method being called will work if the template parameter is not explicitly specified.
See the addtional method added to Class_with_template_method, "templatePassedIn". And the modified STS_OP_temp_test constructor.

};

It's because there's no way for the compiler to tell when it's doing syntax checking that U<int>.templateMethod is a template function. So, you have to tell it, like so:
cwtm.template templateMethod<int>();
This compiles OK with gcc 4.0.1.
Interestingly, VC++9.0 doesn't care either way - it's happy to compile your original code or the variant with template added in.

Awesome! That worked. Thanks you very much.
So, if I owned a copy of the C++ Standard, would I have found the answer there?
How did you know this?

Possibly - the standard can take some decoding at times (yes, I have a copy). I don't know, I didn't look at the standard.
jim258kelly wrote: How did you know this?
Deduction really - you have to think 'what can the compiler infer, given what it knows'. You've told it that U is a template class, taking a single parameter. So when you assert that it has a member 'templateMethod', that's fine - it's willing to accept that. But when you add the '<', what does it mean? There are two options - it could be a less than operator or it could be a template parameter clause introduction - there's ambiguity. So, to disambiguate, either the compiler gets cleverer (looks like VC++2008 has done that) or you have to explicitly tell the compiler that 'templateMethod' is a template.
With templates, the two things that most often come up are 'can the compiler tell that this symbol is a template' (the case you had) or 'can the compiler tell this is a type', at which point you need to add a 'typename' qualifier, similar to the 'template' one. Consider the (contrived) code below. Without the 'typename', it won't compile (not with g++, anyway) because the compiler can't know that A::size_type is actually a type.
#include <vector>
#include <iostream>
template <class A>
struct GetSize
{
typename A::size_type operator()(A const& a) { return a.size(); }
};
int main()
{
std::vector<int> a(10);
std::cout << GetSize<std::vector<int> >()(a) << std::endl;
}
