png with background transparent into gui without border
Hi guys, I would like to make a gui borderless viewing a png image with transparent background.
pretty much has to be visible only the png image with no background..you have any simple example?
still it provides the image with the background...
Parsing binary data frames from an asynchronous source
I was just working on a project that involved decoding a stream of binary data from a serial port in AutoIt. It took me a few hours to figure out how to process the data efficiently in AutoIt and I did not find any helpful examples on how to do so, so I thought I would share my core example and maybe save someone else some time. There may be a more efficient way to do this, but this works well for me.
#cs Author: ToasterKing This is an example of a way to parse streaming binary data that follows a strict format with a header and footer. In this example, each frame is 5 bytes with a 2-byte header of 0xD5AA and a 1-byte footer of 0xAD. The _BinaryParse() function accumulates incoming data in a buffer. Once a footer is found, it searches backward for the header, and if it is in the right position, it extracts the remaining 2 bytes in the middle, then moves on to looking for the next frame. #ce ; The data source might be something asynchronous like serial or TCP, but since this is just an example, I'm just putting the data in a variable. Local $fSomeData $fSomeData = Binary("0xD5AA24B1") ; Binary data constituting almost a complete frame. _BinaryParse($fSomeData) ; Call the function with the received data. It isn't a complete frame, so it is just stored in the buffer until more data is received. $fSomeData = Binary("0xAD62D5AA92E7AD") ; Remainder of the previous frame, one garbage byte (0x62) which should be skipped, and a complete additional frame. _BinaryParse($fSomeData) ; The function should be able to parse both frames now. Func _BinaryParse($fNewData) Local Static $fBinaryReceived = Binary("") ; Buffer for received data ConsoleWrite("Hey, the function is called!" & @CRLF) ; Add new data to the buffer. ; This ridiculous monstrosity is the only way I could find to append binary data to binary data in AutoIt. It must be converted to strings first. ; Both, one, or no substrings will begin with "0x" depending on whether they contained binary data. To be converted back to binary properly, only one instance ; of "0x" must exist at the beginning of the string. $fBinaryReceived = Binary("0x" & StringReplace(String($fBinaryReceived) & String($fNewData),"0x","")) ConsoleWrite("Data in the buffer: " & String($fBinaryReceived) & @CRLF) Local $iLength = BinaryLen($fBinaryReceived) ; Count the bytes in the data If $iLength > 0 Then Local $fBinaryReceivedTemp = $fBinaryReceived ; Create temporary copy to work on Local $fByte1,$fByte2 For $i = 1 To $iLength If BinaryMid($fBinaryReceivedTemp,$i,1) = 0xAD Then ; If the 1-byte footer found ConsoleWrite("Footer found at end of " & $i & " of " & $iLength & " bytes!" & @CRLF) If BinaryMid($fBinaryReceivedTemp,$i - 4,1) = 0xD5 And BinaryMid($fBinaryReceivedTemp,$i - 3,1) = 0xAA Then ; and the 2-byte header is found 4 bytes before that ConsoleWrite("Header found before the footer!" & @CRLF) $fByte1 = BinaryMid($fBinaryReceivedTemp,$i - 2,1) ; Get 1st byte in the body (between header and footer) $fByte2 = BinaryMid($fBinaryReceivedTemp,$i - 1,1) ; Get 2nd byte in the body (between header and footer) ConsoleWrite("Here is the critical data: " & String($fByte1) & " " & String($fByte2) & @CRLF) ; Just display the 2 bytes for demonstration purposes. Normally, you'd do something more useful with it here. EndIf $fBinaryReceived = BinaryMid($fBinaryReceivedTemp,$i + 1) ; Truncate the original data to remove all of the bytes just processed, then continue processing $fBinaryReceivedTemp EndIf Next EndIf EndFunc
Identifying Button in Toolbar When There is no ControID
I want to click on a button that is inside a custom ToolBar on a nonAutoIT created form. I've been using MouseClick but that fails if the toolbar is detached or if the form is resized.
There is no ID associated with the toolbar but there is a handle. I'm thinking that to get the handle I need a ControlID but that only gets me to the toolbar and I'd then need to have a way to identify the position of a button in order to click on it.
I'd found a discussion about identifying the position of a noname button by, I believe, it's Tip text back in December but I can't find it now. Memory is a bit fuzzy on how I even got to the topic because at the time I was searching for something else. I'll continue to search but if anyone has seen the topic, or knows of another solution could you please point me in that direction.
Excel Make Row Some Color
Hey there, I am trying to figure out how to fill an Excel row with a color, if some condition. For example:
$sColor = #FFF000 For $iCC = 1 To Ubound($aArray)-1 $sRange = "A:" & $iCC If _Excel_RangeReady($oWorkbook, $sRange) = "Some String" Then _Excel_FillInRowWithColor($iRowToFillIn, $sColor) Next
Anyone know how to do that? Thanks!
Popup context menu not broadcasting control with multiple widows
I have an issue that is bothering me for quite some time now (Since Autoit3 V22.214.171.124 and still not solved in 126.96.36.199) and i have not found any clue how to solve this particular problem regarding the control of popup-menus for specific controls. I have been searching using many keywords in the hope to find a similar posted issue either on the internet or here on this forum but did not yet stumbled upon it so i have no other option than to post the question (Sorry if there would exist an earlier topic).
Below is an example that demonstrates the issue very clearly if you follow the steps to reproduce:
#include <GuiMenu.au3> #include <GUIConstantsEx.au3> #include <ListViewConstants.au3> #include <WindowsConstants.au3> $TestWindow1 = GUICreate("TestWindow1", 353, 277, 100, 80) $ListView1 = GUICtrlCreateListView("", 8, 8, 338, 262) $ListView1_0 = GUICtrlCreateListViewItem("TestItem1", $ListView1) $ListView1_1 = GUICtrlCreateListViewItem("TestItem2", $ListView1) $ListView1_2 = GUICtrlCreateListViewItem("TestItem3", $ListView1) GUISetState(@SW_SHOW) $TestWindow2 = GUICreate("TestWindow2", 353, 277, 100 + 400, 80) $ListView2 = GUICtrlCreateListView("", 8, 8, 338, 262) $ListView2_0 = GUICtrlCreateListViewItem("TestItem1", $ListView2) $ListView2_1 = GUICtrlCreateListViewItem("TestItem2", $ListView2) $ListView2_2 = GUICtrlCreateListViewItem("TestItem3", $ListView2) GUISetState(@SW_SHOW) GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY") Local $MenuContext, $MenuContext2 Local $ahLVMenu Local $ahLVMenu2 For $i = 0 To 2 $ahLVMenu[$i] = GUICtrlCreateDummy() $ahLVMenu2[$i] = GUICtrlCreateDummy() Next While 1 Local $nMsg = GUIGetMsg(1) Switch $nMsg Case $GUI_EVENT_CLOSE If $nMsg == $TestWindow2 Then GUISetState(@SW_HIDE, $nMsg) Else Exit EndIf Case $ahLVMenu ConsoleWrite("Dialog 1, Item 1" & @CRLF) Case $ahLVMenu ConsoleWrite("Dialog 1, Item 2" & @CRLF) Case $ahLVMenu ConsoleWrite("Dialog 1, Item 3" & @CRLF) Case $ahLVMenu2 ConsoleWrite("Dialog 2, Item 1" & @CRLF) Case $ahLVMenu2 ConsoleWrite("Dialog 2, Item 2" & @CRLF) Case $ahLVMenu2 ConsoleWrite("Dialog 2, Item 3" & @CRLF) EndSwitch WEnd Func WM_NOTIFY($hWnd, $Msg, $wParam, $lParam) #forceref $hWnd, $Msg, $wParam Local $hWndFrom, $iIDFrom, $event, $tNMHDR, $hWndListView, $hWndListView2, $tInfo $hWndListView = $ListView1 $hWndListView2 = $ListView2 Local $tMsgFilter, $hMenu If Not IsHWnd($ListView1) Then $hWndListView = GUICtrlGetHandle($ListView1) If Not IsHWnd($ListView2) Then $hWndListView2 = GUICtrlGetHandle($ListView2) $tNMHDR = DllStructCreate($tagNMHDR, $lParam) $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom")) $iIDFrom = DllStructGetData($tNMHDR, "IDFrom") $event = DllStructGetData($tNMHDR, "Code") Switch $hWndFrom Case $hWndListView2 Switch $event Case $NM_RCLICK ; Sent by a list-view control when the user clicks an item with the right mouse button _LV_PopUpMenu2() ; Show popup context menu in Pharmacist article list EndSwitch Case $hWndListView Switch $event Case $NM_RCLICK ; Sent by a list-view control when the user clicks an item with the right mouse button _LV_PopUpMenu() ; Show popup context menu in Pharmacist article list EndSwitch EndSwitch $hWndFrom = 0 $iIDFrom = 0 $tNMHDR = 0 $hWndListView = 0 $hWndListView2 = 0 $tInfo = 0 $tMsgFilter = 0 $hMenu = 0 Return $GUI_RUNDEFMSG EndFunc ;==>WM_NOTIFY Func _LV_PopUpMenu() $MenuContext = _GUICtrlMenu_CreatePopup(40) _GUICtrlMenu_InsertMenuItem($MenuContext, 0, "Dialog 1, item 1", $ahLVMenu) _GUICtrlMenu_InsertMenuItem($MenuContext, 1, "Dialog 1, item 2", $ahLVMenu) _GUICtrlMenu_InsertMenuItem($MenuContext, 2, "Dialog 1, item 3", $ahLVMenu) _GUICtrlMenu_TrackPopupMenu($MenuContext, $TestWindow1) _GUICtrlMenu_DestroyMenu($MenuContext) Return $GUI_RUNDEFMSG EndFunc ;==>_LV_PopUpMenu Func _LV_PopUpMenu2() $MenuContext2 = _GUICtrlMenu_CreatePopup(40) _GUICtrlMenu_InsertMenuItem($MenuContext2, 0, "Dialog 2, item 1", $ahLVMenu2) _GUICtrlMenu_InsertMenuItem($MenuContext2, 1, "Dialog 2, item 2", $ahLVMenu2) _GUICtrlMenu_InsertMenuItem($MenuContext2, 2, "Dialog 2, item 3", $ahLVMenu2) _GUICtrlMenu_TrackPopupMenu($MenuContext2, $TestWindow2) _GUICtrlMenu_DestroyMenu($MenuContext2) Return $GUI_RUNDEFMSG EndFunc ;==>_LV_PopUpMenu2
I have two window dialogs and two listview controls defined.
Each listview control has its own popup menu and menu items.
The code above works fine as long as both window dialogs are visible.
You can right-click on each listview control and you get the designated menu popped up and if you select an item, the message for the specific item is being written into the console frame for it.
However, if you close window 2, and attempt to trigger the options in the popup menu for window 1, you will notice that the notification messages are no longer being triggered at all.
The popup menu becomes visible if you right-click the area and disappears if you select an option, but the control item no longer sends a notification which means that the attached events for the trapping are no longer being executed.
Now if you switch the code snippets of the window frames being generated, you will notice you can achieve the same issue the other way round, which means that context menu item notifications are being received and trigger an event routine as long as window 1 would then in that case remain open.
So it seems that whichever window is generated the last, that window somehow seems to get attached to the notification messages that are being send by the dummy controls for the context menu items.
Do i misinterpret something here, is there a fix for this issue or did i encountered some kind of bug inside Autoit3?
