Xaaladaha qaarkood, ka dib markii la casriyeeyo in version cusub, ka Windows 10 waxay sababtaa shilalka ama arrimo kale marka ay wacdo CreateWindowEx function ka msctf.dll marka daaqadaha la abuuray in qaar ka mid ah codsiyada 32-bit. Maqaalkan, waxaan fahmi doonaa waxa uu yahay  shaqada CreateWindowEx - sahaminta sababaha suurtagalka ah ee qaladka shaqada ka dibna bixi xalka lagu taliyey si loo yareeyo arrinta.

Fahamka shaqada CreateWindowEx

Codsiyada Windows^(Windows) , oo ay ku jiraan codsiyada NET ee adeegsada Foomamka Windows ama Aasaaska ^(Windows)Soo Bandhigida Windows^{(Windows Presentation Foundation)} ( WPF ), samee daaqadahooda iyaga oo wacaya CreateWindowExA ama CreateWindowExW .

Labada hawloodba waxay ugu yeedhaan hawl caadi ah USER32 kaas oo fulin doona qaar ka mid ah ansaxinta cabbirka, sida qaababka daaqadaha iyo gacan-qabsiga lagu cayimay wicitaanka, gacanta ku haynta abuurista daaqada ilmaha ee MDI haddii WS_EX_MDICHILD qaabka daaqada fidsan la cayimo oo socodsiiya macnaha firfircoonida hadda ee wicitaanka dunta. Haddii wax walba ay ku fiican yihiin USER32-dhinaca^{(USER32-side)} wicitaanka CreateWindowEx , waxay markaas wacdaa kernel-mode ( WIN32K ) hirgelinta CreateWindowEx .

CreateWindowEx waxay qaban doontaa hawlaha soo socda marka ay isku dayayso inay abuurto shay daaqad cusub:

• Go'aanso haddii u samaynta gacanta shayga daaqadda cusub uu dhaafi doono  xadka kootada gacanta Isticmaalaha^(User) ee habka wicitaanka.
• Waxay u qoondaysaa xusuusta shayga cusub ee daaqada ka soo tuulan miiska miiska.
• Waxay u bilawdaa xusuusta shayga daaqadda cusub.
• U abuuraa gacanta shayga daaqada cusub ee miiska gacanta adeegsadaha .^(User)

Sababaha CreateWindowEx guuldarrooyinka

Shuruudaha qaarkood ee kicin kara arrinta shaqada CreateWindowEx ayaa loo tiriyey sida soo socota:

• Nooca daaqada ee la cayimay ma jiro.
• Isticmaalka qaababka daaqadaha ee aan ansax ahayn ama qaababka daaqadaha la fidiyay.
• Isticmaalka^(User) gacan-ku-qabsiga isticmaale ee aan ansax ahayn , sida gacanta-daaqadaha iyo gacan-qablayaasha menu-ga.
• Isku dayga in la abuuro daaqad ilmo iyada oo aan la sheegin daaqada waalidka.
• Isku dayga in la sameeyo daaqad ilmo ama daaqad la leeyahay oo waalidka/milkiilaha la cayimay ayaa iska leh misktop ka duwan dunta wacitaanka.
• Abuuritaanka ilmo ama daaqada la leeyahay waxay dhaafi doontaa xadka daaqada.
• Abuuritaanka shay daaqad cusub ayaa ka badan doona kootada gacanta ee habka wicitaanka.
• Waxaa jira taallo aan ku filneyn oo laga heli karo taallo miiska miiska si loogu qoondeeyo xusuusta shayga daaqadda cusub.
• Ma jiraan wax gelis la heli karo oo ku jira miiska gacanta Isticmaalaha .^(User)

^{(Fix CreateWindowEx)}Hagaaji arrimaha shaqada CreateWindowEx ee 32-bit apps gudaha Windows 10

Microsoft waxay siisay hannaan ku saabsan arrimaha shaqada CreateWindowEx .

Si arrintan looga shaqeeyo, waa inaad dib ugu soo celisaa Windows 10 ku rakibida noocii hore.

Xulashada dib-u-celinta gudaha Windows 10 waxay diyaar u tahay 10 maalmood^{(10 days)} (inta badan kiisaska) ka dib markaad kor u qaaddo Windows 10 rakibidda.

Hawlgalkan waxa uu ilaalinayaa faylashaada gaarka ah, laakiin waxa uu meesha ka saarayaa arjiyada iyo darawalada la rakibay cusboonaysiinta ka dib, waxa uuna sidoo kale beddelaa wixii isbeddel ah ee aad ku samaysay goobaha.

Haddii ikhtiyaarka dib-u-noqoshada aan la heli karin - Backup your personal files , markaas waxaad la xiriiri kartaa taageerada IT-ga ama miiska caawinta ama Taageerada Microsoft^{(Microsoft Support)} si loogu soo celiyo qalabkaaga noocii hore ee Daaqadda 10^{(Window 10)} .

That’s it!

PS : Microsoft waxay ka shaqaynaysaa xallin waxayna ku siin doontaa casriyeyn gudaha Windows 10 siidaynta soo socota.

CreateWindowEx function issues for 32-bit apps in Windows 10

In some casеs, after an upgrade tо a newer version, the Windows 10 causes crashes or other issues when it calls the CreateWindowEx function from msctf.dll when windows are created in some 32-bit applications. In this post, we will understand what the  CreateWindowEx function is – explore the possible causes of this function error and then provide the recommended solution to mitigate the issue.

Understanding the CreateWindowEx function

Windows applications, including .NET applications that use Windows Forms or Windows Presentation Foundation (WPF), create their windows by calling the CreateWindowExA or CreateWindowExW functions.

Both functions internally call a common USER32 function that will perform some parameter validation, such as the window styles and handles specified in the call, handle creating a MDI child window if the WS_EX_MDICHILD extended window style is specified and processes the current activation context for the calling thread. If all is well on the USER32-side of the CreateWindowEx call, it then calls into the kernel-mode (WIN32K) implementation of CreateWindowEx.

CreateWindowEx will perform the following tasks when attempting to create a new window object:

• Determine if creating a handle for the new window object will exceed the User handle quota limit for the calling process.
• Allocates memory for the new window object from the desktop’s heap.
• Initializes the memory for the new window object.
• Creates a handle for the new window object in the User handle table.

Causes of CreateWindowEx failures

Some conditions that can trigger the CreateWindowEx function issue are enumerated as follows:

• The specified window class does not exist.
• Using invalid window styles or extended window styles.
• Using invalid User handles, such as window handles and menu handles.
• Attempting to create a child window without specifying a parent window.
• Attempting to create a child window or an owned window and the specified parent/owner belongs to a different desktop than the calling thread.
• Creating a child or owned window will exceed the nested window limit.
• Creating a new window object will exceed the handle quota for the calling process.
• There is insufficient heap available in the desktop’s heap to allocate memory for the new window object.
• There are no available entries in the User handle table.

Fix CreateWindowEx function issues for 32-bit apps in Windows 10

Microsoft has provided a workaround to the CreateWindowEx function issues.

To work around this issue, you’ll have to roll back your Windows 10 installation to the previous version.

The rollback option in Windows 10 is available for 10 days (in most cases) after you’ve upgraded your Windows 10 installation.

This operation keeps your personal files, but removes applications and drivers that were installed after the upgrade, and also reverses any changes that you made to settings.

If the roll back option isn’t available – backup your personal files, then you can contact your IT support or helpdesk or Microsoft Support for help to restore your device to the previous Window 10 version.

That’s it!

PS: Microsoft is working on a resolution and will provide an update in Windows 10 upcoming release.
