win32汇编弹出对话框

news2024/11/16 20:42:27

之前书上有一个win32 asm 的odbc例子，它有一个窗体，可以执行sql；下面看一下弹出一个录入数据的对话框；

之前它在.code段包含2个单独的asm文件，增加第三个，增加的这个里面是弹出对话框的窗口过程，

include _ListView.asm
include _RecordSet.asm
include input.asm

input.asm，

_InputDlg	proc	uses ebx edi esi,hWnd,uMsg,wParam,lParam

		mov	eax,uMsg

		.if	eax ==	WM_INITDIALOG

		.elseif	eax ==	WM_CLOSE

			invoke	EndDialog,hWnd,NULL

		.else
			mov	eax,FALSE
			ret
		.endif
		mov	eax,TRUE
		ret

_InputDlg	endp

资源文件odbc.rc里面增加一段，

DLG_MAIN DIALOG 51, 78, 465, 237，这是原来的主对话框的资源描述；DLG_INPUT DIALOG 51, 78, 465, 237，这是弹出的对话框的资源描述，这是新加的；

主对话框上增加一个按钮，

PUSHBUTTON "录入(&I)", IDC_INPUT, 412, 51, 50, 14, WS_TABSTOP

点击时弹出input对话框；

资源文件里增加，

#define IDC_INPUT 2010
#define DLG_INPUT 3000

odbc.asm的等值定义里增加，

DLG_INPUT equ 3000
IDC_INPUT equ 2010

这是之前程序的弹出主对话框的语句，

invoke DialogBoxParam,eax,DLG_MAIN,NULL,offset _ProcDlgMain,0

DLG_MAIN，是对话框资源标识，_ProcDlgMain是对话框的窗口过程；

在之前的主对话框窗口过程的消息处理分支的WM_COMMAND处理分支下面增加IDC_INPUT按钮的处理，

.if   eax ==   WM_COMMAND
           mov   eax,wParam

           .if   ax ==   IDC_CONN_STR
。。。。。。
           .elseif   ax ==   IDC_SQL
。。。。。。
           .elseif   ax ==   IDC_CONN
。。。。。。
           .elseif   ax ==   IDC_DISCONN
。。。。。。
.elseif   ax ==   IDC_INPUT
               invoke   DialogBoxParam,hInstance,DLG_INPUT,NULL,offset _InputDlg,NULL
           .endif

当点击IDC_INPUT按钮时，执行

invoke DialogBoxParam,hInstance,DLG_INPUT,NULL,offset _InputDlg,NULL

_InputDlg是弹出对话框的窗口过程；

如果不小心加或写错.endif，如下图有2个.endif，就会出现下图错误，
