Hi,

I have a panel (C++) with a lot of buttons representing images a user can select.

My idea is, to prevent me for defining an event per button, to use the same event for every button when pressed and to get the Control Name of the pressed button, to know which image was selected.

Is there a possibility to get the Control Name of the pressed button?

I don't think you are going to save much time here...as you have to create a button for every image, give the button a unique control name, then attach to a logical event...why not create a unique logical event and have an Events Case Handler...

But you could use this source to check if a control with the passed control name has focus.

{
  HWND fhWnd;
  HWND hWnd = ObPanelAPI::GetControlHandleByName(&(1:));
  fhWnd = GetFocus();
  if (fhWnd == hWnd)
  {
   &(2:) = "1";
  }
}

Will search around for some source like GetControNameOfControlInFocus or something similar

what we need is something like:

{ 

  HWND fhWnd; 

  fhWnd = GetFocus();

  &(1:)  = ObPanelAPI::GetControlNameByHandle(fhWnd); 

} 

Just need to find "GetControlNameByHandle"  if it exists or not by CA

maybe some vb CodeGuru Forums yuk

but on a train so cant really test..laters

Hi,

Try this ,

HWND hwndCtrl = ObPanelAPI::GetControlHandleByName("*Event Source"); //Event Source

or

HWND hwndCtrl = ObPanelAPI::GetControlHandleByName("*Focus");

why? We have the HANDLE of the current focused control but we want to get the Control NAME by the HANDLE

Those two are special values, useful for generic process or creating patterns.

Add event to the panel - Control Defaults.

Use the Control handle from either (*Event Source) or (*Focus) to get other control properties.

The following got me Left label of all fields when mouse was moved over it.

#include "OBCTRL.H"

HWND hwndCtrl = ObPanelAPI::GetControlHandleByName("*Event Source"); //Event Source

int length=GetWindowTextLength(hwndCtrl);

char Text[260];

if (Text) GetWindowText(hwndCtrl,(LPSTR)Text,length+2);

Text[length+2]='\0';

&(3:)=ObCharFld(Text);

AfxMessageBox(Text);

does GetWindowText get the ControlName of a button? Maybe Markus could add text to the button to determine which button was pressed but really adding dedicated logical events seem easier than anything else but still fun to try

GetWindowText would get the text on the control.

Using  control handle, you may get most properties asociated with control.

May be Markus needs to get the image name or source for the control using its handle.

First, thanks to ashfaq.m.ahmed  and  GeorgeJeffcock for the help.

Ashfaq, I tried your code, but I only get the "Text" and not the "Control Name" of the button.

If it's not possible to get the Contro Name, how can I get the image name (as you mentionned above)?

Hi Markus,

Try with this .....

HBM_GETPIC

HBM_GETBITMAP

HBM_GETPALETTE
