Question

का उपयोग कर किसी अन्य एप्लिकेशन की विंडो शैली को संशोधित करें मेरा एप्लिकेशन एक और एप्लिकेशन शुरू करता है। जिससे, मैं उस एप्लिकेशन के शीर्षक पट्टी को हटाना चाहता हूं जो सी # का उपयोग शुरू कर दिया गया है।

मैं नीचे दिए गए कोड के टुकड़े से शुरू कैसे कर सकता हूं?

//Get current style 
lCurStyle = GetWindowLong(hwnd, GWL_STYLE) 

//remove titlebar elements 
lCurStyle = lCurStyle And Not WS_CAPTION 
lCurStyle = lCurStyle And Not WS_SYSMENU 
lCurStyle = lCurStyle And Not WS_THICKFRAME 
lCurStyle = lCurStyle And Not WS_MINIMIZE 
lCurStyle = lCurStyle And Not WS_MAXIMIZEBOX 

//apply new style 
SetWindowLong hwnd, GWL_STYLE, lCurStyle 

//reapply a 3d border 
lCurStyle = GetWindowLong(hwnd, GWL_EXSTYLE) 

SetWindowLong hwnd, GWL_EXSTYLE, lCurStyle Or WS_EX_DLGMODALFRAME 

//redraw 
SetWindowPos hwnd, 0, 0, 0, 0, 0, SWP_NOMOVE Or SWP_NOSIZE Or SWP_FRAMECHANGED
