I have a class.

I want to find the windows' handle of that class (not handle() property, which returns the classid).

This is usefull for using some api functions on that handle.

Thanks :)

The object.xml() returns an id inside - is that id an hexadecimal value of the object id.

if I write the following:

int h;

h = hex2int(<the hexa code>);

winapi::getWindowDC(h); // returns 0.

winapi:getWindowText(h); // return "" even the object has text.

So, the assumption that object.xml(), which returns xml with the id inside it, may be wrong.

(Or the pseudo-code above is wrong somehow).

Thanks :)

X++ classes does not have a Windows handle. From your description it appears that you are using the wrong APIs. What are you trying to accomplish?

Not all the classes have the hwnd.

I need to know what is the specific windows handle of the component

(Need to do some manipulation on that object by some real WIN-API function, that X++ doesn't have the commands for it - just need a simple example for any api - not using hwnd, because not all the classes have the hwnd function).

Thanks :)

As Huzaifa pointed out, you can use infolog.hwnd() to get the Windows handle for the AX32.exe component.

Windows handles are only required when rendering graphics - so most classes do not need a Windows handle. What is the type of the class in question? And what API are you attempting to use?

OK.

BTW - for infolog, there might be a problem, because sometimes infolog returns null value.

There is a problem on hebrew characters on some occasions ...

(And there might be other situation, where I need using API function directly, so this is just a sample ...)

i.e there is a string like (and should be on hebrew - you should look the following from right to left. this is called : RTLReading ...)

אבג (123)

xyz (123)

The hebrew (first line is shown with brackets not in place - if you cannot see it the second line is transfered to :

123) xyz)

There is no quite solution on AX for all components (it is paritally solved), so I need to call some api function.

This is called by :

int l;

int h;

#winapi

;

// I need to find the handle ... how can I do that?

l = WinAPI::getWindowLong(h, #GWL_EXSTYLE);

l = l | #WS_EX_RTLREADING;

WinAPI::setWindowLong(h, #GWL_EXSTYLE, l);

I don't know the handle, so I cannot solve problem as solution above ...

There are many cases, such as doing alignment to bottom of some elements (good for reports) and this is a thing good to be known.

Thanks :)
