You've got the pirate sounds down pat. Now let's see how you fare at the fishing part.

I don't know about "good" but there seem to be plenty of flounders around today.

I'm guessing MFC is "helping" you by disabling menu items that there's no
command handler (or enabler) for.

Did you declare any event for these items?

Im not sure about the relevance in your problem, but a menu item that is not related with any function is always disabled. If you append the items to a menu, but you dont connect it with any called function / message... I think you won't be able to have them enabled

Hello everyone,
I am using Visual Studio 2005 to debug a Pocket PC 2003 application on Poacket PC 2003 SE Emulator (I am using ARMV4 architecture). When using F5 to execute the application, the break points I have set before debug (F5) becomes, the information from the break points is,
--------------------
The breakpoint will not currently be hit. No executable code is currently loaded at this location.
--------------------
I am setting the break point to the 1st line of main function. I am wondering what is the check list to solve this issue to make the application debuggable?
thanks in advance,
George

(1) i want to change a 32bits color bmp image into 8bits color bmp image,
anyone who has the source code?
(2)as to 24bits image, one pixel has 3 bytes, the 3 bytes respectively is the B ,G,R value, how about the 32bits iamge? from low byte to heigh byte , what is the value of the 4 bytes?
thanks

RGBA. A = alpha = transparency
the only free RGBA to 8-bit code i'm aware of is part of one of the LibPNG utilities.

hey Chris Losinger, i only know the concept of alpha, but would you please give me the detail explain of it? why 32bits iamge has the alpha value?
as your reply, the sequence for the 4 bytes value of every pixel is R ,G, B, A, but i did an example, only the sequence is A, B , G ,R, the output image is well, what is the matter?
thanks !

the alpha byte controls the transparency of that pixel - it allows the background to show through that one pixel.it's useful if you want to create images that can blend with their background, or that don't have straight edges.

the actual order will depend on the application or API that creates or uses the image.

|

i have changed the Alpha byte for some values, but the image displayed has no change, when does the alpha byte value work?
|
|
|
|
|
how are you drawing it? many drawing APIs do not pay attention to alpha values.

only if you're talking about DIB/BMPs. the rest of the world gets the order right

I create a windows form apllication, p2pport.
My form file name is Dlg.I get some errors.
error C2027: use of undefined type 'p2pport::CParams'
error C2227: left of '->setValue' must point to class/struct/union/generic type
in Dlg.cpp
params->setValue("Y", "123");
in my Dlg.h file
#include "params.h";<br />
namespace p2pport {<br />
<br />
using namespace System;<br />
...............................<br />
<br />
public ref class Dlg : public System::Windows::Forms::Form<br />
{<br />
CParams* params;<br />
}<br />
}
in my param.h file
class CParams{<br />
void setvalue(char* k, char* v);<br />
}
in my params.cpp
void CParams::setValue(char* k, char* v){ ..... return; }
Can anybody tell me what's wrong with it?
Appreciate your reply.

Have you declared the pointer to your class before using it?
#include "MyClass.h"
MyClass* pMC;
pMC->DoSomething (...);
will work, but...
#include "MyClass.h"
pMC->DoSomething (...);
will give you the error you are posting

THx for reply.
Is that means I can't declare it in Dlg.h?
I have to put "MyClass* pMC;" to Dlg.cpp?

I dont say that you can not, I made it in header with member variables and in code with the local variables.
I have given you an example of that error code and the meaning. I don't think just putting the MyClass* pMC; in your Dlg.cpp will solve it. Although you can try it as well.
I think is more a question about the scope and how the relationships between classes are done. Your code is not recognising the other class, there is a point where the connections break.
