我有此PHP文件与服务器通信。该文件需要VB.NET程序中的两个变量，即坐标x，y。
我设法生成了一个32x32按钮矩阵。每个按钮应将PHP文件发送两个字符串的变量。假设第一行具有y =" 001"和该行x =" 001"，" 002"等的32个按钮，等等。
显然，我有一个可以执行发送的函数，但是我如何分辨第一行您应该发送y =" 001"，并基于该行的按钮，该按钮从001到032。

i通常在C 中代码。我可以在vb.net中做类似的事情吗？
void btn(button btnarray(), int d)
{
char y;
char x()={"001","002""0xx","032"};
for(int i=0;i<d;i++)
{
if(i<=32)
{
btnarray(i).click=
y="001";
inviaphp(y,x(i));
}
}
}
和是否适用于所有32行？
最终工作代码要感谢Drdonut：

以某种方式，您必须将按钮本身的按钮的coRdine放在按钮本身中，因此单击时可以将其发送。假设您的按钮是Windows表单按钮，则可以使用按钮的name字段：
for row as integer = 0 to 31
for col as integer = 0 to 31
btnArray(row*32+col).name = (row+1).ToString("D3") + (col+1).ToString("D3")
end for
end for
您可以在制作按钮阵列的循环后立即添加此代码。
此代码将按钮的name属性设置为RowColumn。示例：第14行的按钮，第5列将获取名称：014005。按钮。
这样，所有名称都设置为： 00x00y。
在您的clickButton函数中，sender对象是按钮，因此您可以通过：
dim row as integer = Convert.toInt32(sender.name.subString(0,3))
dim col as integer = Convert.toInt32(sender.name.subString(3,3))
