I do it like this: ExtHandle = FindWindow("CalssName","Caption"); PostMessage(ExtHandle,WM_SYSCOMMAND,SC_RESTORE,0); SetForegroundWindow(ExtHandle); The minimized ext_app comes to foreground, it works. But if I want to minimize the ext_app (which was restore/comes to foreground) it doesn't work. I can click to the minimize button but nothing happens. I use the system menu but nothing happens too. After I restore the ext_app by my application I can't minimize the ext_app anymore.

After I use the ShowWindow function I can't re minimize the application. I just rechecked my console app that uses that code. I use EnumWindows(EnumProc,0); to get a list of hwnds that the user can select. I then run that handle through the code I gave, and even restored minimized windows can be minimized again. If that code isn't working for you then either the hwnds aren't the proper ones, or VCL is otherwise screwing with you.

I do it like this: ExtHandle = FindWindow("CalssName","Caption"); PostMessage(ExtHandle,WM_SYSCOMMAND,SC_RESTORE,0); SetForegroundWindow(ExtHandle); I would expect this to be problematic because you're posting the restore which IMO will not get processed until after you have tried to being it to front.

I use the system menu but nothing happens too. After I restore the ext_app by my application I can't minimize the ext_app anymore. You can if you right click it's TaskBar Icon and play with it. The problem is that you're confusing Windows with respect to the actual window state by minimizing a minimized window or restoring a restored window. Bob is correct that you need to use IsIconic and that you're calling it with the wrong HWND. IsIconic doesn't work with child windows so you need to call it on the Application's Handle. Once you get the Target HWND, add this: HWND hWnd = reinterpret_cast<HWND>( ::GetWindowLong(TargetHwnd, GWL_HWNDPARENT) ); if( IsIconic(hWnd) ) ::ShowWindow( hWnd, SW_RESTORE ); ::SetForegroundWindow( hWnd ); ~ JD Back to top JD Guest Posted: Sat Apr 21, 2007 1:59 am    Post subject: Re: Foreground another application Bob Gonder <notbg (AT) notmindspring (DOT) invalid> wrote: Quote: [...] or VCL is otherwise screwing with you. For shame, for shame, for shame! Please see my reply to Andreas. I had a very similar problem long ago and posted several times and no one could help. Then one day ... YOU pointed out that IsIconic wants the Application's Handle! Getting too old for this <g> ? ~ JD Back to top Remy Lebeau (TeamB) Guest Posted: Sat Apr 21, 2007 2:22 am    Post subject: Re: Foreground another application "JD" <nospam (AT) nospam (DOT) com> wrote in message news:462928d0$1 (AT) newsgroups (DOT) borland.com... Quote: HWND hWnd = reinterpret_cast<HWND>( ::GetWindowLong(TargetHwnd, GWL_HWNDPARENT) ); Use GetParent() instead: HWND hWnd = ::GetParent(TargetHwnd); Also, keep in mind that in BDS 2007, the TApplication object no longer controls the taskbar button. I'm not sure if the TApplication window is even still the parent for TForm windows anymore.

I do use GetParent else where .... but other than the extra typing, is there any difference? Quote: Also, keep in mind that in BDS 2007, the TApplication object no longer controls the taskbar button. I'm not sure if the TApplication window is even still the parent for TForm windows anymore. I've been diverted time and time again with BCB6 stuff and I'm angry about that! Thanks for the heads-up. I'll look at it as soon as I get BDS installed (which looks like some time after the next BDS is released). ~ JD Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         BorlandTalk.com Forum Index -> C++ Builder (Native API) All times are GMT Page 1 of 1   Jump to: Select a forum C++ Builder Newsgroups----------------C++ BuilderC++ Builder (ActiveX)C++ Builder (Announcements)C++ Builder (Command Line Tools)C++ Builder DatabasesC++ Builder Databases (ADO)C++ Builder Databases (Desktop)C++ Builder Databases (InterBase Express)C++ Builder Databases (Multi-Tier)C++ Builder Databases (SQL Servers)C++ Builder (Graphics)C++ Builder (IDE)C++ Builder (Internet)C++ Builder (Internet Socket)C++ Builder (Internet Web)C++ Builder (Jobs)C++ Builder (Language)C++ Builder (Language C++)C++ Builder (Compatibility with MFC)C++ Builder (Native API)C++ Builder (Non-Technical)C++ Builder (Students)C++ Builder (Third Party Tools)C++ Builder (Upgrade)C++ Builder (VCL)C++ Builder (VCL Components Usage)C++ Builder (VCL Components Development)C++ Builder (VCL Usage)C++ Builder (WinAPI)C++ Builder Installation Delphi Newsgroups----------------Delphi (General)Delphi ActiveX Controls UsageDelphi ActiveX Controls DevelopmentDelphi As400Delphi DatabasesDelphi Databases (ADO)Delphi Databases (dbExpress)Delphi Databases (Desktop)Delphi Databases (InterBase Express)Delphi Databases (Multi-Tier)Delphi Databases (SQL Servers)Delphi DeploymentDelphi GraphicsDelphi IDEDelphi InternationalizationDelphi InternetDelphi Internet Isapi-WebBrokerDelphi Internet WebSnapDelphi Internet WinsockDelphi JobsDelphi Language BASMDelphi Language ObjectPascalDelphi Model Driven Architecture (General)Delphi Model Driven Architecture (Third Party)Delphi MultimediaDelphi Native APIDelphi Non-TechnicalDelphi ObjectPascalDelphi OLE AutomationDelphi OO designDelphi OpenToolsAPIDelphi Reporting-ChartingDelphi RTLDelphi StudentsDelphi TeamSourceDelphi Thirdparty ToolsDelphi Thirdparty Tools (General)Delphi Thirdparty Tools (IntraWeb)Delphi Thirdparty Tools (RaveReports)Delphi UpgradeDelphi VCLDelphi VCL ComponentsDelphi VCL Components UsingDelphi VCL Components WritingDelphi WebServices SOAPDelphi WinAPIDelphi XMLDelphi Installationcomp.lang.pascal.delphi.components.misccomp.lang.pascal.delphi.components.usagecomp.lang.pascal.delphi.components.writingcomp.lang.pascal.delphi.databasescomp.lang.pascal.delphi.misccomp.sources.delphi JBuilder Newsgroups----------------JBuilderJBuilder AnnouncementsJBuilder Applet IssuesJBuilder As400JBuilder CompilerJBuilder CORBA/RMIJBuilder DatabasesJBuilder DB SwingJBuilder DebuggerJBuilder DeploymentJBuilder DocumentationJBuilder EnterpriseJBuilder HandheldJBuilder IDEJBuilder JavaJBuilder JavaAPIJBuilder Java LanguageJBuilder Java SwingJBuilder Java BeansJBuilder Java Beans UsageJBuilder Java Beans DevelopmentJBuilder JBCLJBuilder JDataStoreJBuilder JobsJBuilder LinuxJBuilder MacintoshJBuilder & MobileSetJBuilder MultiLingual AppsJBuilder Non-TechnicalJBuilder OpenToolsJBuilder Servlets (JSP)JBuilder StudentsJBuilder Team DevelopmentJBuilder Thirdparty ToolsJBuilder UpgradeJBuilder Installation InterBase Newsgroups----------------InterBaseInterBase Bug DiscussionInterBase GeneralInterBase IBConsoleInterBase OpenSourceInterBase ReplicationInterBase SQLInterBase ThirdpartyInterBase Installation Miscellaneous Borland Newsgroups----------------AppCenterAppServerEnteraVisiBroker  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2006 phpBB Group SEO toolkit © 2004-2006 webmedic.
