VB的控制台程式执行时的Dos视窗,如何做出像VC执行时显示进度条?如图...

这个真不会，以前Qbasic时，有定位命令，

VB6，你输出退格键试试。

以前有人教過用ＶＣ做這個，所以反過來想，如果把ＶＣ用的指令拿到ＶＢ來當ＡＰＩ去搞，也許。。。
不過據我問人的結果，前幾行好搞，就用ＶＢ產生ＢＡＴ檔，並去執行它就行了。有echo on
但是進度條就比較麻煩了，雖說可以用ＡＰＩ取取得視窗句柄，但是要在定點重複寫字，就不會了，
用ＳＨＥＬＬ ＣＯＭＭＡＮＤ也是會返回視窗句柄。

網路上是回說是能做但是很麻煩，還不如改用別種語言來做。

c下如此（一种模拟状态）  vb下还没弄过控制台

#include <stdio.h>
#include <windows.h>

int main(void)
{ 
    int i,j;
    for(i=1;i<=100;i++)
    {
        printf("当前运行了%6.2lf%% .",(double)i/100.0*100);
        for(j=0;j<20;j++) printf("\b");
        Sleep(200);
    }
    printf("\n");
    return 0;

}

看看这个http://visualbasic.有没有帮助.

感觉有戏....等我把C调试完再来试试看...

先跟着范例做,基本上可以做出来,但是要进度条那功能,就还要再研究研究.

只要知道如何对窗口输入输出就好办了,进度条试试
...
ConsolePrint 后面跟字符串，得到的进度百分比要转换为字符。另外还有一个光标位置问题，只能在固定位置显示百分比，只有把百分比格式化为固定位数，下次显示前用退格字符清掉。

这有中文的资料...

偷懒做出来,但是数字部分还是要想怎退格.
