i was interested in seeing your copy of winuser.h , since that's what your compiler is looking at.
but, you should also take a look at your stdafx.h file and everything that it #includes, and make sure there are no obvious syntax errors there
|
|
|
|
|
I use Visual Assist, and the bracket after the line-extern "C" is red, so I may lose the latter bracket.
But I can not find where.
|
|
|
|
|
it is usually at the bottom of the file

Have you compiled a VC++ 6.0 project with VC++ 8.0?
|
|
|
|
|
no, only VC++6.0.
I just wanted to check winuser.h, maybe edited something unconsciously
|

On VC++ 2003...
I get tons of odd errors when I make a copy of a project (build directories and all) and try to compile it in the new location.
I have to do a rebuild (or delete the build directories) and the gazillion errors go away. I haven't a clue if this would help but it's worth a try.

Check your stdafx.h for missing semicolon or some other syntax errors.
There is some problem with your include statements. As the errors point towards this.

I see a BIG DIFFERENT in performance, between the following 2 methoods, WHY IS THAT?:
---------------Method 1-----------------------------
Class
{
Member x
Function()
{
Write to x;
}
}
Main()
{
Call function()
}
--------------Method 2:--------------------------------
Class
{
Function(member x)
{
Write to the member x;
}
}
Main()
{
Member x ;
Call function (x)
}

if the second method is faster, it could be because the constructor or destructor of 'Member' takes a long time.
if the first method is faster, it could be because you're doing a deep copy of 'x' when passing it.

Could you post the code you used in the testing?
Best,
Jun

They will execute at the same speed if you pass x by reference in Method 2. Otherwise, if Member is a complex datatype, Method 2 will run slower since it has to copy the value of x into the function before entering the function.

Hello,
I have create a CComboBox with like that and when I click on the droplist it happend nothing but when I use push left or right key the value chang.

How can I create or witch propertie should I use to do what I want to do.

Do you need to create it at runtime? Does changing the (height) value of 20 to something larger make any difference?

Hi,
I'm developing a NT Service using .NET 2.0, its a multithreaded TCP server, this service will handle connections from many enterprise applications.
The challenge is to avoid a single-point-of-failure. My first idea was create a service instance capable of just redirect incoming calls to service instances which implement the concrete service.
This solution decrease service unavailability risk, but AFAIK real cluster services like App Center uses another approach, it creates a virtual server that can redirect incoming calls to an available server, this approach really solve the single-point-of-failure problem.
I'd like to use the same solution, how it can be done ?
Thanks for any help !

need (preferably) straight C code to retreive document properties from a microsoft word document. C++ is OK. but prefer C.
i have been looking at other versions, and can't get my head around the various snippets of code published. would like complete functionality.
thanks in advance.

share the resource like bitmap, dialog box or others.
|
|
|
|
|
Just add the .rc file to both projects (including the resource.h header file). This method may be quick, but it's wrong. You should really create a resource only dll, and link that to both projects.

Hi all,
I have an application that shows a dialog with a listview control. I added a "Print" button to this dialog (with ID "IDC_PRINT"). Now, all of a sudden, the close button (the cross in the top-right corner) acts as if this print button has been pressed rather than closing the dialog. How do I get things right again?
Thanks in advance for any advice,
William

Hi again,
Sorry, I should have investigated further. For some reason, Studio decided to define IDC_PRINT with a value of 2 rather than to add it into the normal sequence of IDC values. After doing so manually, things are in order again.
Regards,
William

Hi,
I am trying to apply the sort() algorithm on a vector of structs. I want the vector to be sorted according to one of the struct fields. I see two ways in which this could be done, and neither seems to work.
Here are the struct and the vector:
<br />
struct item_calculation <br />
{<br />
int item_num;<br />
float weight;<br />
float contribution;<br />
float prediction;<br />
};<br />
<br />
vector<item_calculation> found_items;
I want the vector "found_items" to be sorted by the field "prediction".
The first way to do the task is defining a comparison function and sending it do sort() as a parameter:
bool less_than( item_calculation a, item_calculation b ) {<br />
return a.prediction < b.prediction;<br />
}; <br />
.<br />
.<br />
.<br />
sort(found_items.begin(), found_items.end(), less_than);
This results with the errors: "error C3867: 'CCFEApp::less_than': function call missing argument list; use '&CCFEApp::less_than' to create a pointer to member."; "error C2780: 'void std::sort(_RanIt,_RanIt)' : expects 2 arguments - 3 provided"
when using "&CCFEApp::less_than" I get the error: "error C2914: 'std::sort' : cannot deduce template argument as function argument is ambiguous".
The second way to do the task is by overloading the "<" operator:
bool operator<(item_calculation a, item_calculation b) {<br />
return a.prediction < b.prediction;<br />
};
gives: "error C2804: binary 'operator <' has too many parameters".
After changing to:
<br />
bool operator<(item_calculation b) {<br />
return prediction < b.prediction;<br />
};
one gets: "error C2065: 'prediction' : undeclared identifier".
I would apreciate any help.
Thanks,
Avi.
P.S. I am working under Visual Studio 2005.
