The following is a problem I have been having with every single VisualBasic application for some time, and I ask for your help now: Every single VisualBasic application I have tried lacks the minimize and maximize buttons, even when the application is supposed to have them. In addition, the taskbar button is missing (on Gnome 1.4.x/Metacity 2.10.3 under Fedora 4), so there is no way to recall the application once the window is obscured by another application, except by clearing the desktop. The applications show the buttons on the virtual desktop, and the problem arises only when the application uses the window manager for its own window. This problem was confirmed on Metacity and MWM. As far as I can tell, this affects Visual Basic apps only. The applications from Wine (regedit, for example) show correct decorations, and so do some tools from MS Visual Studio. I modified x11drv/window.c to display the Windows attributes before setting hints for the window manager. Here is what I got: Tested regedit (wine), depends.exe (native, MS Visual Studio), windiff.exe (native, MS Visual Studio), dbgridtest.exe (native, VisualBasic app), pruebatransparency.exe (native, VisualBasic app). Entries with asterisks lack min/max buttons as explained. regedit wine fixme:x11drv:X11DRV_set_wm_hints hwnd = 0x00010022 style = 0x04cf0200 ex_style = 0x00000100 fixme:x11drv:displayStyles style =

VisualBasic apps have an odd pattern of window initialization. The very first window in the other C/C++ apps is also the one to be set with a WS_VISIBLE style, but this is not the case for VisualBasic apps. However, I am unable to tell if this is relevant to the issue. Thanks for your attention. Alex Villacís Lasso
