Hello members,
the standart button (IDC_BUTTONX) in VC++ 6.0 contains only the Click- and the DoubleClick-Event. Is there a way to detect, if the left or the right mouse button was clicked on the button.
I hope, anyone can help me

By default, the mouse click events handled by a button control are left clicks only. Right clicks are not handled for button controls.
Best,

Hope I understood your question
if you write a drived class CButton and declare Rclick on this class then you can use Rclickbutton

Yes but the sample could be built and then run to test with your hardware correct? Have you don that?

No I have NO WIA experience. I do however understand that if the "sample" project works with your hardware and your application DOES NOT, then there is a problem with your code. I still cannot determine from your posts if the "sample" application works with your hardware.

I have a propertypage and the first page is a listctrl. The whole
propertypage is a listctrl.
If I put alot of data in the listctrl, scrollbars to the right
appear on the listctrl and they also appear on the propertypage.
Is there any way for the listctrl and the propertypage to sort of
become one or work together more? I dont like the 2-scrollbars but I
can probably figure out a way to remove the scroll from the property
page. If I try to increase the width of the propertypage, the listctrl
doesnt increase with it. Instead a gap appears between the listctrl
and propertypage end. I tried making the first propertypage a ListView
but I could get it to compile.
My main question is, is there a better way for the listctrl and property
page to work together? Any response, any sample project, any direction
any one can give me will be greatly appreciated.
Sincerely,
Danielle Brina

I'm a little confused.
Do you want the property page to actually grow vertically together with the list control if the data in the list control overruns the initial size?
Why don't you just fix the size of the list control AND the property page and allow the list control's vertical or horizontal scroll to do its job?

Yes. Sort of make the listctrl grow dynamically with the property page.

So the property page is sizable?

Do you mean the first page of a property sheet has a list control?

I was looking at the WinSpy artical (http://www.codeproject.com/threads/winspy.asp), which describes how to extract text from any control (I think it uses WM_GETTEXT).
But this doesn't work on windows that display rich text. Does anyone know how to get to extract the text in this case?
By the way, I'm not sure that the window in question is the rich edit control. It says that it is a "AfxFrameOrView" class, but that could just be the parent window.
|

Richtext is not added to a control with a simple sendmessage, it is streamed in and streamed out a little at a time. If you wanted to use a similar method to winspy, you would need to write the whole streaming functions and inject a callback.

Thanks for the answer!
Do you know any working example that does that?
|
|
|
|
|
Now, I found some code to extract the text using EM_STREAMOUT, but it doesn't work. It could be that the window is not a rich edit control. It there anyway to test if the window is a rich edit?
|
|
|
|

when u get a handle of window. Use GetClassName to get class of window. Compare it with "RICHEDIT".

Nevermind, I figured another way to do it.

I'm using a parent class that holds pointers to child classes (parent-child is the application's terminology, not indicating heirarchy in c++).
The parent class has an array of pointers to children named "children"
To save space (and I need all I can get), I want to dynamically allocate this array. I have been using malloc/realloc with success in the past, but recently it's been reporting heap corruption:
"Heap block at 01720DD8 modified at 01720DE4 past requested size of 4"
before stopping at this line in memcpy_s.c:
"memcpy(dst, src, count);"
The realloc command in the code that is initiating the problem is indicated below. This array is initially malloc'd in the constructor of the class with a size of one child pointer.
bool parent::addchild(child *childToAdd){
//////////////////////////////
// Add child to children
//////////////////////////////
numchildren++;
children = (child**)realloc(children,(numchildren * sizeof(child*))); //<--Error occurs here
children[(numchildren-1)] = childToAdd;
return TRUE;
}
Thanks for any help

Slightly different error in Debug (original post was for Release):
Heap corruption:
"Heap block at 01F13EA0 modified at 01F13ED0 past requested size of 28"
Stops at the end brace of this function in mlock.c:
void __cdecl _unlock (
int locknum
)
{
/*
* leave the critical section.
*/
LeaveCriticalSection( _locktable[locknum].lock );
}

Read your error, the answer is there.

You requested a block of memory of size 28 bytes, it was given to you at address 01F13EA0, but you tried writing to it at address 01F13ED0 which is over the 28 byte limit. Basicly you are writing past the end of the array somewhere in your code.
