What I am looking for is a way to wait for the mutex (ghAccess) to become available while allowing messages to be processed.

Hi,
I keep getting a syntax error "C2059: syntax error : 'constant'"
When I try and specify a capacity for a vector based type.
<br />
...<br />
typedef std::vector<myClass> MyClassVector;<br />
...<br />
MyClassVector mcv (100);
<br />
I just stare and stare yet I cannot see the syntax error?
Thanks!

Which compiler are you using? The following compiles fine in VC++ 6.0sp5:
#include <vector>
class myClass{};
typedef std::vector<myClass> MyClassVector;
MyClassVector mcv (100);
int main()
{
return 0;
}

This is from MSDN Library:
If the error message occurs on a symbol immediately following a typedef'd variable, ensure that the variable has been defined somewhere in the source code.

That does seem to apply to my situation as if I don't specify
a capacity i get no syntax error.
<br />
...<br />
typedef std::vector<myClass> myClassVector;<br />
...<br />
myClassVector mcv;

have you tried
mcv.reserve(100);

I have a DLL class that I am exporting,
// Observer Class
class APA_API CStateObserver
{
...
}
class APA_API CStateMachine
{
public:
void PushObserver(CStateObserver * inpObserver);
private:
std::deque<cstateobserver*> m_dqObservers;
}
APA_API is the define that resolves to the correct __dellspec(lalalalalal) etc...
I get this compiler warning message,
warning C4251: 'm_dqObservers' : class 'std::deque<class cstateobserver="" *,class="" std::allocator<class="" *=""> >' needs to have dll-interface to be used by clients of class 'CStateMac
I have 'Warnings as Errors' set so this warning is a real problem.
What are my options?

Did you include the header for the deque container?

disable it - I think this is one of the ones you can safely ignore (like warning 4786 about long names)
Also make sure you don't expose it directly, such as
class Foo {
public:
map<int,int> & getTheIntMap() {
return m_map;
}
private:
map<int,int> m_map;
}
exposing it like so will cause you all sorts of problems - just don't go there.
Wrap all access to the collection with functions for adding and removing, which it appears you are doing anyways.
Also you might consider using STLPort - which may give you fewer headaches

Specifically I get "LINK : fatal error LNK1561: entry point must be defined"
I searched MSDN and with Google but no luck. Did this happen to anyone else? How did you get it to build?

Generally speaking, a DLL wants a function called DllMain as its default entry point. Do some MSDN searches on DllMain and you should see lots of stuff. There is a sample called DllHusk that is somewhat illustrative.

Thanks! It turns out it was a typo in the include directory listing. I had accidentally deleted the period in front of \

check for _USRDLL being defined. See if subsystem is windows. Do you have any weird linker customizations? Just a thought (I actually don't have VC7 so I may be completely off base )

So yes I guess I had a pretty weird linker customization goin on.

Hi. I want to call one method, which i have declared in a Dialog´s Class from other class. So, in the second class i have a varible CDialog* pWnd; which is initialized by SetParent(CDialog *p). Then, in the dialog I call secondclass.SetParent(this). then i add the #include "mydlg.h" in seconclass.cpp
All that work fine. However, when i try to use any dialogclass's method in secondclass as ((CmyDlg*)pWnd)->NuevaTarea(strRecvd); doesn´t work
But when i compile this message appear : error C2065: 'IDD_SPOOLERSUR_DIALOG' : undeclared identifier
error C2057: expected constant expression
(SpoolerSur is my Cdialog class)

You also need to include the "resource.h" file in secondclass.cpp

How to send message from VC7 to IE6 ??? (eg. select internet page)

One solution is FindWindow() and SendMessage().

To open a page you can use ShellExecute()

Hi,
Is there a way to execute a MFC app with an arguments? I would like to do something like:
Get a Filename and Filepath from a database. Launch the app with that file loaded.
Thanks for helping.

Everything's beautiful if you look at it long enough...
