Problem with Pop Up Gui and _GUICtrlRichEdit_Create

Recommended Posts

bobsyuruncle

Good day to the autoit community.

I am having an issue with the _GUICtrlRichEdit on a pop-up gui box. I have cobbled a short script together that replicates the issue. Simply run the script and click the button for the pop-up gui with the richedit box. If you close the pop-up gui and re-click the button, the richedit box fails to load on subsequent pop-up gui launches.
 

#include <GuiRichEdit.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

Opt("GUIOnEventMode", 1)
$Form1_1 = GUICreate("hubconsole", 655, 697)
GUISetOnEvent($GUI_EVENT_CLOSE, "Form1_1Close")
$gethubbutton = GUICtrlCreateButton("Get Info", 501, 129, 81, 25)
GUICtrlSetOnEvent(-1, "Main")
GUISetState(@SW_SHOW)

Func Form1_1Close()
exit
EndFunc

While 1
    Sleep(100)
WEnd

Func Main()
    Local $hGui, $hRichEdit, $iMsg
    $hGui = GUICreate("Example (" & StringTrimRight(@ScriptName, 4) & ")", 320, 350, -1, -1)
    global $richgui = $hGui
    GUISetOnEvent($GUI_EVENT_CLOSE, "Form2_1Close")
    global $hRichEdit = _GUICtrlRichEdit_Create($hGui, "This is a test.", 10, 10, 300, 220, _
            BitOR($ES_MULTILINE, $WS_VSCROLL, $ES_AUTOVSCROLL))
    _GUICtrlRichEdit_AppendText($hRichEdit, @CR & "This is more text")
    GUISetState()

EndFunc

    Func Form2_1Close()
        _GUICtrlRichEdit_Destroy($hRichEdit) ; needed unless script crashes
        GUIDelete($richgui)
    EndFunc

 

Some further information from diagnostic:
The first cycle around shows no @error's for the deconstructor Form2_1Close().. so the richedit destroy and guidelete both happen.
When I click the button for the second launch, I see the pop-up gui has a new HWnd.. example: 1st click (0x00514B6) 2nd click (0x000614B6)
on the line    " global $hRichEdit = _GUICtrlRichEdit_Create($hGui...  " I see value to @error of 1 which isn't detailed in the helpfile of the function, but if I dig into the include I see error 1 gets set when:  If Not _WinAPI_IsClassName($hWnd, $_GRE_sRTFClassName) Then Return SetError(1, 0, 0) ; Invalid Window handle for _GUICtrlRichEdit_Create 1st parameter

I'm stuck at this point as I can't figure why "_WinAPI_IsClassName($hWnd, $_GRE_sRTFClassName" comes back with a failure on subsequent launches of the popup.

Maybe try to remove the Local and Global declarations of $hRichEdit and then declare it as global at the top of the script, outside a func

Thanks for the suggestion. No luck unfortunately:

Pasting partial sample showing the modified code. Everything else is same as example in 1st post:

Opt("GUIOnEventMode", 1)
$Form1_1 = GUICreate("hubconsole", 655, 697)
GUISetOnEvent($GUI_EVENT_CLOSE, "Form1_1Close")
$gethubbutton = GUICtrlCreateButton("Get Hub Info", 501, 129, 81, 25)
GUICtrlSetOnEvent(-1, "Main")
GUISetState(@SW_SHOW)
global $richgui, $hRichEdit

Func Form1_1Close()
exit
EndFunc

While 1
    Sleep(100)
WEnd

Func Main()
    Local $hGui, $hRichEdit, $iMsg
    $hGui = GUICreate("Example (" & StringTrimRight(@ScriptName, 4) & ")", 320, 350, -1, -1)
    $richgui = $hGui
    GUISetOnEvent($GUI_EVENT_CLOSE, "Form2_1Close")
    $hRichEdit = _GUICtrlRichEdit_Create($hGui, "This is a test.", 10, 10, 300, 220, _
            BitOR($ES_MULTILINE, $WS_VSCROLL, $ES_AUTOVSCROLL))
    _GUICtrlRichEdit_AppendText($hRichEdit, @CR & "This is more text")
    GUISetState()

EndFunc

Try to remove the local declaration of  $hRichEdit  here :

Func Main()
    Local $hGui, $hRichEdit, $iMsg

Thanks, I removed the line "Local $hGui, $hRichEdit, $iMsg" from the script.

Same Behavior unfortunately

Func Main()
    $hGui = GUICreate("Example (" & StringTrimRight(@ScriptName, 4) & ")", 320, 350, -1, -1)
    $richgui = $hGui
    GUISetOnEvent($GUI_EVENT_CLOSE, "Form2_1Close")
    $hRichEdit = _GUICtrlRichEdit_Create($hGui, "This is a test.", 10, 10, 300, 220, _
            BitOR($ES_MULTILINE, $WS_VSCROLL, $ES_AUTOVSCROLL))
    _GUICtrlRichEdit_AppendText($hRichEdit, @CR & "This is more text")
    GUISetState()

EndFunc

Is this a bug with _GUICtrlRichEdit_Create?
Can anybody shed some light on what maybe "_WinAPI_IsClassName($hWnd, $_GRE_sRTFClassName"  is doing or why the gui somehow changes that value on multiple launch?

Thanks

No bug, this works for me without issue :

#include <GuiRichEdit.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

Opt("GUIOnEventMode", 1)

Global $hGui, $hRichEdit

$Form1_1 = GUICreate("hubconsole", 655, 697)
GUISetOnEvent($GUI_EVENT_CLOSE, "Form1_1Close")
$gethubbutton = GUICtrlCreateButton("Get Info", 501, 129, 81, 25)
GUICtrlSetOnEvent(-1, "Main")
GUISetState()

While 1
    Sleep(100)
WEnd

Func Main()
    $hGui = GUICreate("Example (" & StringTrimRight(@ScriptName, 4) & ")", 320, 350, -1, -1)
    GUISetOnEvent($GUI_EVENT_CLOSE, "Form2_1Close")
    $hRichEdit = _GUICtrlRichEdit_Create($hGui, "This is a test.", 10, 10, 300, 220, _
        BitOR($ES_MULTILINE, $WS_VSCROLL, $ES_AUTOVSCROLL))
    _GUICtrlRichEdit_AppendText($hRichEdit, @CR & "This is more text")
    GUISetState()
    ; msgbox(0,"", "gui : " & $hGui &@crlf& "richedit : " & $hRichEdit)
EndFunc

Func Form1_1Close()
    exit
EndFunc

Func Form2_1Close()
    _GUICtrlRichEdit_Destroy($hRichEdit) ; needed unless script crashes
    GUIDelete($hGui)
    ; msgbox(0,"", "gui : " & $hGui &@crlf& "richedit : " & $hRichEdit)
EndFunc

*Expires in 30 days

Can you please take a look and verify if this is not occuring when you run the same code?

Thanks

I ran the code Mikell posted and it works fine for me using AutoIt 3.3.12.0.

You're running an older version of AutoIt, you have probably run into a bug that was in the _GUICtrlRichEdit_Create function that was fixed in later versions.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

THANK YOU!!!!

I had searched the forums before but did not see the bug post the first scan through. This was in fact a problem with using an older autoit engine (Couldn't be helped in this project).
Relevant bug post found here: http://www.autoitscript.com/forum/topic/139788-unexpected-result-in-_guictrlrichedit_create/

Based on the information I found on that bug post I have modified _GUICtrlRichEdit_Create to manually resolve the issue for this project.

      Good evening everyone
      First, I want to apologize with you for the title not very clear, but I thought a little bit on which title to set at the thread, and this is the one that came in mind.
      Now, let me explain what I'm trying to understand.

      I am making an application ( with n clients ), with an SQLite Database, which has a Main form, and n sub-forms... 
      Since these sub-forms are called several times, because they are used to add or update records to the Database, I put the code that generates the GUI of these sub-forms in Functions.
      There are two sub-forms which are "treated" as two main forms, since even them have n sub-forms, which perform various tasks.
      Where am I stucked?

      For the Main form I created a Status Bar, in order to display messages ( add/delete/update/search results ), and it works perfectly with all the forms which don't have other sub-forms.
      For the two forms, which indeed have n sub-forms, I created two separated Status Bars, which are (re)created everytime I call the function that then displays the form.
      Practically, I can't set icons to these two Status Bars, and I don't know why.
      I'm really sorry that I don't feel clear enough, so, here you are an example of what I am saying.
      I recreated exactly what my script does:
      #include <GuiButton.au3> #include <GUIConstantsEx.au3> #include <GuiStatusBar.au3> #include <WindowsConstants.au3> Opt("GUIOnEventMode", 1) Global $frmSubForm, _ $txtSubFormField, _ $sbSubFormStatusBar, _ $objSB_IconError = _WinAPI_LoadShell32Icon(109), _ $objSB_IconInformation = _WinAPI_LoadShell32Icon(277) #Region ### START Koda GUI section ### Form= $frmMainForm = GUICreate("Main Form", 300, 300, -1, -1) GUISetOnEvent($GUI_EVENT_CLOSE, "ExitApplication") $sbMainStatusBar = _GUICtrlStatusBar_Create($frmMainForm) $btnCreateSubForm = GUICtrlCreateButton("Create Sub Form", 105, 110, 75, 41, BitOR($BS_CENTER,$BS_VCENTER,$BS_MULTILINE)) GUICtrlSetOnEvent(-1, "GenerateSubForm") GUICtrlSetFont(-1, 10, 400, 0, "Arial") _GUICtrlStatusBar_SetSimple($sbMainStatusBar) _GUICtrlStatusBar_SetText($sbMainStatusBar, "") GUISetState(@SW_SHOW, $frmMainForm) #EndRegion ### END Koda GUI section ### While 1 Sleep(100) WEnd Func ExitApplication() Exit EndFunc Func GenerateSubForm() #Region ### START Koda GUI section ### Form= $frmSubForm = GUICreate("Sub-Form", 300, 300, -1, -1, -1, -1, $frmMainForm) GUISetOnEvent($GUI_EVENT_CLOSE, "DeleteSubForm") $txtSubFormField = GUICtrlCreateInput("", 0, 0, 100, 20) $btnCheckSubFormField = GUICtrlCreateButton("Check Field", 105, 110, 75, 41, BitOR($BS_CENTER,$BS_VCENTER,$BS_MULTILINE)) GUICtrlSetOnEvent(-1, "CheckSubFormField") GUICtrlSetFont(-1, 10, 400, 0, "Arial") $sbSubFormStatusBar = _GUICtrlStatusBar_Create($frmSubForm) _GUICtrlStatusBar_SetSimple($sbSubFormStatusBar) _GUICtrlStatusBar_SetText($sbSubFormStatusBar, "") GUISetState(@SW_SHOW, $frmSubForm) GUISetState(@SW_DISABLE, $frmMainForm) #EndRegion ### END Koda GUI section ### EndFunc Func DeleteSubForm() ; Declared Globally => $frmSubForm GUIDelete($frmSubForm) GUISetState(@SW_ENABLE, $frmMainForm) EndFunc Func WriteToStatusBar($sbStatusBar, $objSB_Icon, $strText) _GUICtrlStatusBar_SetIcon($sbStatusBar, 0, $objSB_Icon) _GUICtrlStatusBar_SetText($sbStatusBar, $strText) ConsoleWrite("Icon Handle: " & $objSB_Icon & @CRLF) EndFunc Func CheckSubFormField() ; Declared Globally => $txtSubFormField If GUICtrlRead($txtSubFormField) = "" Then ; Declared Globally => $sbStatusBar WriteToStatusBar($sbSubFormStatusBar, $objSB_IconError, "Field NOK.") Else WriteToStatusBar($sbSubFormStatusBar, $objSB_IconInformation, "Field OK.") EndIf EndFunc The text is set, but icon is not.
      Could someone please tell me why?
      Thanks everyone in advance  

      Best Regards.

      Hi, everybody
      I look for GUI whose behavior similar to the message of an email client or antivirus
      In other words:
          Any PC screen able to calculate the size
          To consider the Task bar size
          To find the lower corner on the right/below and to nestle on it

      Notes:
      In GUI the GUICtrlCreateEdit field (as option) - that can be received and displayed through variable information
      Thanks a lot
      PS
      I use the translator, excuse if something is not clear

      Hi,
      I'd like to show a progress bar for an operation performed by an external program my script is running silently, I want to show it in a GUI I created using the GUICtrlCreateProgress but I have no idea how to do it.
      The important thing to point out is that there's no way of knowing how long the external program will run, as it is a file splitter and it depends on the size of file it splits and the split parts size.
      Can someone point me in the right direction or give me an example how to do so?
      This is my RunWait command:
      RunWait($MYFILES1 & '\fsplit.exe -split ' & $Size & ' mb ' & $File & " -f " & $File & "." & $extension) It uses multiple variables declared and set earlier in the script, how will I got about having the progress of that command shown using GUICtrlCreateProgress ? Is it possible?
      Thank you.

      I was playing around with simple GUI creation.  I tend to like parameter driven coding (in prior life (years ago) as Clipper/FoxPro/dBase coder).  Just wanted to see what I could do with a GUI.
      #Region options, includes Opt('MustDeclareVars', 1) Opt("GUIOnEventMode", 1) ; Change to OnEvent mode #include <GUIConstantsEx.au3> #EndRegion options, includes Global Const $nCols = 2, $nRows = 6, $nSpacer = 10, $nBtnWidth = 150, $nBtnHeight = 30 Global $xName = 0, $xID = 0 Global $nGUIWidth = ($nCols * $nBtnWidth) + (($nCols + 1) * $nSpacer) Global $nGUIHeight = ($nRows * $nBtnHeight) + (($nRows + 1) * $nSpacer) Global $hMainGUI = GUICreate("Calculated GUI", $nGUIWidth, $nGUIHeight, -1, -1) For $xRows = 1 to $nRows ;in this arrangement, tabbing is left to right, then next row For $xCols = 1 to $nCols ;reverse the order of this line with the prior line for top to bottom tabbing, then next col $xName += 1 $xID += 1 Global $Dummy = GUICtrlCreateButton("Button" & $xName, _ ($nBtnWidth * ($xCols - 1)) + (($xCols - 1) * $nSpacer) + $nSpacer, _ ($nBtnHeight* ($xRows - 1)) + (($xRows - 1) * $nSpacer) + $nSpacer, _ $nBtnWidth, _ $nBtnHeight) GUICtrlSetOnEvent($xID+2, "Handler") Next Next GUISetOnEvent($GUI_EVENT_CLOSE, "CloseApp") GUISetState(@SW_SHOW) While 1 Sleep(10) WEnd Func CloseApp() Exit EndFunc Func Handler() MsgBox(0,0,"Button " & @GUI_CtrlId - 2) EndFunc
