If you're using MFC/ATL, CImage class satisfy your requirements.

If you aren't using MFC/ATL then GDI+ maybe an option, see, for instance, [^].

Assuming you have a working bitmap (.bmp) example, one way to know for sure would be try it with other formats.

i have tried it with other formats but actually as i am using loadimage to load HBITMAP and this function does not work with other formats thatswhy this example is not working with other type of images.
still i could not find a way to load my HBITMAP for other formats..

What are the possibilities to remove the MFC dependency, from an MFC extension DLL?
Means, the interface class cannot have MFC dependency, but no need to remove MFC from internal code (functionality side). I believe it is not possible, but i would like to know your opinions
For example, my extension dll has a custom button (named CCustomBtn) derived from CButton. In the client side, CCustomBtn is used to create control variable for the button to get the custom look and feel. So what I need is, avoid the MFC dependancy from this CCustomBtn class (and in the include header), with/without affecting the client side. ('without affecting' is preferred, but i think it is impossible)
Please share your ideas.
Thank you.

If you have a class derived from an MFC class then everywhere you use that
class will have a dependency on MFC.

Yes. But my requirement is to use the same dll for both old vc6 projects and for new vc8/9 projects. So there is an option to avoid the MFC dependency. As far as I know, extension dll should be compiled using the same compiler and libraries those are to be used for the client side. So if there is a chance to avoid the MFC dependency with out degrading the functionality of the MFC extension dll, my requirement is satisfied.

I see two choices:
1) Don't use MFC in the DLL.
2) Make the DLL a "regular DLL" Linked to MFC
Option 1 may not be an option.
Option 2 may require significant changes to the App-DLL interface.

Thank you. I think I have to stick on the Extension DLL and provide a different one compiled with VC8/9 for newer applications.

My MFC is rusty, but IIRC MFC extension DLLs must link with the DLL version of MFC. So basically, you can't do what you're asking for.

template<class T1, class T2 = T1> class X2
{
};
please explain what it means (class T2 = T1)?
|
|
|
|
|
If you are not specifying the type T2, then it will be T1...
Like X2<int> a;
same as X2<int,int> a;
|
|
|
|
|
|
Consider the following example
template<class class="" t2="T1"> class X
{
public:
T1 a;
T2 b;
};
void main()
{
X<int> m1;
m1.a = 10;
m1.b = 10;
X<int,float> m2;
m2.a = 10;
m2.b = 10.0;
}</class>
Here m1 is having both members as int type. It is created as X<int>, means T1 is int, and T2 which is not specified explicitly, became the default type. That is T1, which is int. So T2 is also int.
In the second case, m2, T1 is int and T2 is specified as float explicitly. Now T2 is float.
Hope now it is clear.
|
|
|
|
|
|
template<class T1, class T2 = T1> class X2 {};
T2 is an optional parameter hence class X2 will be specialised using <t1,> if T2 is not specified,
for instance
X2 <int> x2;
is the same of
X2 <int, int> x2;

My application is currently working on Vista. When I invoke through Domain1\user1 , it works fine.
When I log as DOMAIN2\user and try to invoke my application it crashes.
I have a observations. In one of the dll which is being used while application is invoked, I changed project settings. I have set Optimization settings as Minimize size. When I rebuid the binary and replace it. Now the application is working fine even as DOMAIN2\user2.
Can I know why this behaviour difference and how did crash get solved.
I am using VC++6.0 on Vista.
Thanks.

Unless there is a compiler bug (very unlikely) you have a bug in your code that only shows up with optimizations on. Likely this is some kind of memory allocation bug. Impossible to say without seeing your code.

Hi,
I cannot get VS2005 to work properly on my Vista when I use the dialog app wizard, nothing happens - I have the Sp1 update etc installed for VS. Can someone tell me if there is a workaround for me to get the files the wizard would create, including a blank resource template that I can visually drag and drop controls onto, and if there are still any issues with linking controls to code as I've seen before (I've not had VS installed for ages, and only previously on XP). Would these issues go away on an XP based system.
thanks for any help
cheers

Hi all,
This only happens on the release version of my project and it does not happen on the debug version. Also I have the same additional dependencies.
