Hi David,
Please let us know if this is the kind of thing you had in mind?

I have no problem changing the imagex from some code resulting from either another buitton being pushed or some other action. I have troublem seting when the imagex button is pressed and released to change the imagex.
I need to make a button icon change on the click of the mouse OR button selected and space bar being set. Then change the button back. I can't get it to do this. any Ideas using your code in the previous answer as a basis?BarryComment

You mean you want a different image while the button is down?I need to make a button icon change on the click of the mouse OR button selected and space bar being set. Then change the button back. I can't get it to do this. any Ideas using your code in the previous answer as a basis?
I don't know how to do that with IMAGEX controls but with owner-drawn buttons it's pretty straightforward... on WM_DRAWITEM you can query the state using the BM_GETSTATE message looking for BST_PUSHED and select your image accordingly.

Barry,
Seems you need either a IMGBUTTON or IMGBUTTONX control..
Code:#Compile Exe #Dim All #Include "WIN32API.INC" #Resource "ImageTest.pbr" %IDC_IMGBUTTON1 = 101 %IDC_IMGBUTTONX = 102 CallBack Function DlgProc() Static ImgBtnFlag As Long Select Case As Long CbMsg Case %WM_InitDialog Case %WM_Command Select Case As Long CbCtl Case %IDC_IMGBUTTON1 If CbCtlMsg = %BN_Clicked Then Local UpDwnFlag As Long Control Get Check CbHndl, %IDC_IMGBUTTON1 To UpDwnFlag Control Set Imgbutton CbHndl, %IDC_IMGBUTTON1, IIF$(UpDwnFlag, "IMGFILE2", "IMGFILE1") End If Case %IDC_IMGBUTTONX If CbCtlMsg = %BN_Clicked Then Control Set ImgbuttonX CbHndl, %IDC_IMGBUTTONX, IIF$(ImgBtnFlag, "IMGFILE2", "IMGFILE1") ImgBtnFlag = IsFalse ImgBtnFlag End If Case %IdCancel If CbCtlMsg = %BN_Clicked Then Dialog End CbHndl, 0 End If End Select End Select End Function Function PbMain() As Long Local hDlg As Dword Dialog New 0, "ImageTest", , , 240, 150, %WS_Caption Or %WS_SysMenu To hDlg Control Add Imgbutton, hDlg, %IDC_IMGBUTTON1, "IMGFILE1", 40, 40, 50, 50, %WS_Tabstop Or %BS_PushLike Or %BS_AutoCheckbox Control Add ImgbuttonX, hDlg, %IDC_IMGBUTTONX, "IMGFILE2", 140, 40, 50, 50 Control Add Button, hDlg, %IdCancel, "Exit", 180, 130, 50, 15 Dialog Show Modal hDlg, Call DlgProc End Function '------------------/ #IF 0 //ImageTest.rc // Use your own files here IMGFILE1 Bitmap "C:\WINDOWS\Gone Fishing.bmp" //Image no.1 could be icons.. //IMGFILE1 ICON "help2.ico" IMGFILE2 Bitmap "C:\WINDOWS\Coffee Bean.bmp" //Image no.2 //IMGFILE2 ICON "tips.ico" //..etc #ENDIFRgds, DaveComment

I alread do that on thestate of a varablle in a timer. If a certan time is met, the image changes in the imagex box. I'm tring to chage it when the button is pressed, but can't. Using setcursor, I can fire a beep, but can't change te image (even with control redraw)Originally posted by Michael Mattias View PostBarryComment

I don't know the standard controls (IMGBUTTON, IMGBUTTONX) are really suitable for doing this, although you might be able to subclass the control and change the image on WM_KEYDOWN (space) and/or or WM_LBUTTONDOWN. (and back on "up").
If you want to stay in DDT-Land, well, that's beyond my pay grade....unless.....
I think Borje Hagsten's RRBUTTON can do this out of the can... CONTROL ADD "rrbutton" etc etc. ... that RRBUTTON #INCLUDE file is around here somewhere.

Dave,
Not exactly what I want. I want one image when the button is not clicked. Then the Image changes while the Left button is down. When it is released, I want the original image back.I've already tried what you show. I just can't trigger on %WM_LBUTTONUPBarryComment

Barry, I have something that works as you describe- here's the callback that does it. It's probably not best practice, but the same trick works great for my motor control programs where button-down runs the motor and button-up stops it:
I don't know if the redraws are necessary, just stuck 'em in there.Code:CALLBACK FUNCTION ShowDIALOG1Proc() LOCAL MyButton AS LONG SELECT CASE AS LONG CB.MSG CASE %WM_INITDIALOG ' Initialization handler CASE %WM_NCACTIVATE STATIC hWndSaveFocus AS DWORD IF ISFALSE CB.WPARAM THEN ' Save control focus hWndSaveFocus = GetFocus() ELSEIF hWndSaveFocus THEN ' Restore control focus SetFocus(hWndSaveFocus) hWndSaveFocus = 0 END IF CASE %WM_SETCURSOR MyButton = GetDlgCtrlId(CB.WPARAM) SELECT CASE MyButton CASE %IDC_IMGBUTTON1 SELECT CASE HI(INTEGER, CB.LPARAM) CASE %WM_LBUTTONDOWN '&H201 'put in new image here CONTROL SET IMGBUTTON CB.HNDL, %IDC_IMGBUTTON1, "#" + FORMAT$(%IDR_IMGFILE2) CONTROL REDRAW CB.HNDL, %IDC_IMGBUTTON1 FUNCTION = 1 END SELECT END SELECT CASE %WM_COMMAND ' Process control notifications SELECT CASE AS LONG CB.CTL CASE %IDC_IMGBUTTON1 IF CB.CTLMSG = %BN_CLICKED OR CB.CTLMSG = 1 THEN 'put original image in here CONTROL SET IMGBUTTON CB.HNDL, %IDC_IMGBUTTON1, "#" + FORMAT$(%IDR_IMGFILE1) CONTROL REDRAW CB.HNDL, %IDC_IMGBUTTON1 FUNCTION = 1 END IF END SELECT END SELECT END FUNCTION

That looks exactly like what I have tried, but you zip file does show it works. Only difference I see is that WM_SETCURSOR is higher up in the SELECT, but that should not matter. Must be a little typo in mine. Thanks.BarryComment

Found my problem. Even though the documention in the help file is wrong, I should have caught it.
For CONTROL SET IMGBUTTONX
For CONTROL SET IMAGEXPurpose
Change the icon or bitmap displayed in an IMAGEX control. The new image is re-sized to fit the size of the control.
So I was using CONTROL SET IMAGEX instead of CONTROL SET IMGBUTTONXPurpose
Change the icon or bitmap displayed in an IMAGEX control. The new image is re-sized to fit the size of the control.
If I was looking for how to change a IMGBUTTONX then I would have found the correct one, but both said the same thing on purpose and I did not read futher.BarryComment

Cool! Obviously I got this from you or someone else on the board, as I'm not clever enough to figure out the button down trap myself. I would have posted complete code but it was done with PBForms and would have been cluttered up for the non-forms users. PBForms is quite smart about images, but I still had to manually edit the resource file for the second image and let PBForms rebuild the resource. IMO, in this case it would have been easier without PBForms, but I use it almost exclusively now.
Best,

This compilable code uses Conrad's suggestion plus shows how to get the same effect with subclassing.
- Subclassing allows you to respond to the space bar too.

Dave, you've nicely trapped the "slid off the button" condition that was discussed in the original post. In this application that's certainly desirable. In my motor control app, the ability to purposely slide off a depressed control and keep the motor running hands free turned out to be a useful feature. I'd never go back and "fix" it!
"um... er, yeah, I meant for it to work that way"
Best,
