vb.net 如何区分动态加载相同控件的事件处理，如加载了两个combox，添加事件后如何区分选择了其中哪一个
就算有两个combox也是不能同名的。
不会触发同一个事件，两个事件分开写所以没必要去区分，相同的部分写到一个过程里面来调用，就算区分也可以通过获取焦点在哪里来判断。

这是代码，文字性的内容自己去做。
Q2: VB.net 读取文本文件？
1、实现上传按钮方法代码。
2、判断图片对象是否为空代码。
3、取得数据库字段 dt.Rows(0)("Pic")方法代码。
4、字节数组转换为Image类型方法代码。
5、处理SQL中操作Image类型方法代码。
6、实现的上传结果。
Q3: vb.net加载嵌入式资源（DLL,自定义资源）
很简单，点击菜单“项目”--“WindowsApplication1属性”
在属性面板里点“资源”，这里可添加字符串资源、图片资源、多媒体资源等等。
使用资源很简单，举例如下：
Label1.Text = My.Resources.String1
PictureBox1.Image = My.Resources.小猫
Q4: vb.net 定长字符串,如何加载资源中指定语言种类的字符串。
其中每16个连续(string id连续)vb.net加载字典的字符串存为一个RT_STRING资源。在内存中表示为16个变长结构体。
struct rt_string_block{unsigned short cch;
wchar_t str [0];};下面这段代码可以加载指定语言vb.net加载字典的字符串。返值为0时，表示失败vb.net加载字典；大于零，结果为字符串的长度(以宽字符记)。如果你需要ANSI字符串，请使用WideCharToMultiByte来进行转换。
