其中的文字是可以改变的,比如“とある科学の超电磁炮”“とある定時の超級冒泡”“とある特別の作死技巧”,修改文本框的文本就能看到其中的文字发生改变。
此外颜色也可以修改的,点左下角的两个按钮就可以改变颜色了。点“宋体”按钮还可以改变字体。但是我拖拉Label控件的时候就是针对宋体进行修改的,改成别的字体不一定好看。
产生图片后,点“存储”就能将其保存为24位色的BMP。鼠标点击图片然后按下Ctrl+C就能直接复制图像到剪贴板,然后就能在QQ的聊天窗口里按Ctrl+V粘贴,就能发送了。是不是很方便?
这个程序是用VB写的。入门向的程序。代码很简单。
其实重点在于它对CreateObject这个VB函数的使用。VB使用这个函数进行COM类的使用。对于这个函数的资料一般不多,因为我们可以用别的方式达到目的,比如用API,或者换别的语言编程等。然而研究VB的这个还是比较有意义的——能更好地使用VB了。相比较而言使用API会略微降低代码可读性。
这里放出部分代码示例。大家可以看到CreateObject还是相当方便的——就是没有自动提示功能令人厌烦!不过MSDN都能找到资料。
公用文件对话框:Dim DlgObj As Object
Set DlgObj = CreateObject("MSComDlg.CommonDialog")
DlgObj.Filter = "24位BMP位图(*.bmp)|*.bmp|显示所有文件(*.*)|*.*" '文件扩展名,用|隔开,一般是“提示|扩展名|提示|扩展名|提示|扩展名……”等方式。
DlgObj.ShowSave '如果是打开文件就用ShowOpen,如果是保存文件就用ShowSave
If Len(DlgObj.FileName) Then MsgBox "保存到" & DlgObj.FileName 复制代码 公用字体对话框:Dim DlgObj As Object
Set DlgObj = CreateObject("MSComDlg.CommonDialog")
DlgObj.FontName = cmdFont.Caption
DlgObj.ShowFont
MsgBox "字体:" & DlgObj.FontName
MsgBox "是否斜体:" & DlgObj.FontItalic
MsgBox "是否粗体:" & DlgObj.FontBold
MsgBox "是否下划线:" & DlgObj.FontUnderline 复制代码 公用颜色对话框:Dim DlgObj As Object
Set DlgObj = CreateObject("MSComDlg.CommonDialog")
DlgObj.Color = cmdColor1.BackColor
DlgObj.ShowColor
MsgBox "颜色值:" & Hex$(DlgObj.Color) 复制代码 其实我喜欢VB的一个地方就是——它一般不使用方括号用作表达式,而是用圆括号,因此在发帖的时候就不会因为方括号导致论坛解析帖子内容出现BUG。典型的例子是C语言经常出现“[i]”这种使用数组元素的方式,对于论坛这是“斜体”([i]中间是斜体内容[/i])就会导致帖子很不好看。。
但是从各种方面来说C的可读性、可移植性和灵活性都很高。但是我一般不会使用C语言写这样的程序,因为嫌麻烦。
