VB中怎么让自己写的程序在开机时自动启动？

VB怎样使程序在开机时自动启动？？？

　首先要声明这三个API函数，它们分别是：RegSetValue、RegCreateKey、RegCloseKey，其作用是设置某一个主键的键值、创建一个主键、关闭对注册表主键的操作。

　Private

Declare

Function

RegSetValue

Lib

"advapi32.dll"

Alias

"RegSetValueA"

(ByVal

hKey

As

Long,

ByVal

lpSubKey

As

String,

ByVal

dwType

As

Long,

ByVal

lpData

As

String,

ByVal

cbData

As

Long)

As

Long

　Private

Declare

Function

RegCreateKey

Lib

"advapi32.dll"

Alias

"RegCreateKeyA"

(ByVal

hKey

As

Long,

ByVal

lpSubKey

As

String,

phkResult

As

Long)

As

Long

　Private

Declare

Function

RegCloseKey

Lib

"advapi32.dll"

(ByVal

hKey

As

Long)

As

Long

然后声明以下两个常数，要进行注册表写入的位置是在HKEY_LOCAL_MACHINE下，我们可以在VB自带的API文本查看器中找到这些常数的定义方法。

　Private

Const

HKEY_LOCAL_MACHINE

=

H80000002

　Private

Const

REG_SZ

=

1

然后使用如下语句就行了，你可以把这段代码放在程序的某个位置：

'写注册表

Dim

Ret2

As

Long

'打开

HKEY_LOCAL_MACHINE　下的　software\microsoft\windows\currentVersion\runServices　主键

RegCreateKey

HKEY_LOCAL_MACHINE,

"software\microsoft\windows\currentVersion\runServices",

Ret2

'将此主键下的“默认”项的值改为"c:\windows\system\myprogram.exe"，也就是要开机运行的程序路径

RegSetValue

Ret2,

vbNullString,

REG_SZ,

"c:\windows\system\sysinfo2.exe",

4

'关闭对主键的操作

RegCloseKey

Ret2

vb点虐 实现开机自启

程序源代码如下:

main()

{

int i,j,k;

printf("\n");

for(i=1;i5;i++)／*以下为三重循环*/

　for(j=1;j5;j++)　

for (k=1;k5;k++)

　{

if (i!=ki!=jj!=k) 　/*确保i、j、k三位互不相同*/

printf("%d,%d,%d\n",i,j,k);

　 }

}

main()

{

long int i;

int bonus1,bonus2,bonus4,bonus6,bonus10,bonus;

scanf("%ld",i);

bonus1=100000*0.1;bonus2=bonus1+100000*0.75;

bonus4=bonus2+200000*0.5;

bonus6=bonus4+200000*0.3;

bonus10=bonus6+400000*0.15;

　if(i=100000)

bonus=i*0.1;

　else if(i=200000)

　bonus=bonus1+(i-100000)*0.075;

else if(i=400000)

bonus=bonus2+(i-200000)*0.05;

　else if(i=600000)

　bonus=bonus4+(i-400000)*0.03;

else if(i=1000000)

bonus=bonus6+(i-600000)*0.015;

　else

bonus=bonus10+(i-1000000)*0.01;

printf("bonus=%d",bonus);

}
