Ⅱ 怎么写组件并且上传到github
首先确认：拥有一个GitHub账号，已经安装 Git。
先在GitHub创建一个项目，名字随意，尽量全部小写字母，避免随后会碰到的URL冲突问题
本地运行Git，随意选个目录，将刚才创建的项目clone下来。
在项目的根目录下新建文件 _config.yml ，填写 baseurl: /blogdemo ， blogdemo是你的项目名称，这一行内容规定了整个网站的根路径。
在项目的根目录下新建文件 _config.yml ，填写 baseurl: /blogdemo ， blogdemo是你的项目名称，这一行内容规定了整个网站的根路径。
回到git bash, 检查一下 git status ，确认 _config.yml 与 index.html 无误后 add，commit，保持使用Git的良好习惯，记得添加提交描述然后推送到GitHub，这里注意，因为我们使用的是GitHub Pages中的 Project Pages, GitHub仅会将分支 gh-pages 下的内容进行自动生成操作， 所以本地的 master 分支应推送到远端的 gh-pages 分支。
稍微等待一下，最多10分钟（通常不用那么久啦），访问yourname.github.com/blogdemo ，（其中 yourname 是你的GitHub帐户名，blogdemo则是你的项目名）就会看见你新建的项目了
Ⅲ extjs怎样判断formpanel中有文件上传组件
java代码中对文件上传的处理可以参考struct的文件上传，但是在返回处理结果时必须设置 response.setContentType("text/HTML"); 否则文件上传后，会出现一个下载对话框； var formPanel = new Ext.FormPanel({ }） 中必须加入fileUpload:true
Ⅳ asp后台图片用组件上传了，但是数据库一直添加不了，有源文件，请高手帮忙解决，急
我从我做的系统中截取了一部分（与你的提问有关联的）代码，并稍做注释，希望能帮到你：
----------------------------------------------------
...
Co_picture = Trim(Request.Form("Co_picture"))
Pictures=Split(Co_picture,",")
For X = 0 to Ubound(Pictures)
IF instr(Pictures(X),"uploadfile")>0 and Len(Pictures(X)) > 11 Then
Pictures(X) = right(Pictures(X),Len(Pictures(X))-11)
Else
End IF
Co_pictures = Co_pictures & "uploadfile/" & Pictures(X) & ","
Next
'Stream.CharSet = "utf-8"
Select Case Action
Case "save"
IF Trim(Request.Form("Co_name"))="" Then
Response.Write("<script language=javascript>alert('对不起,标题不能为空！');history.back();</script>")
Response.End()
End IF
IF Trim(Request.Form("Co_picture"))="" Then
Response.Write("<script language=javascript>alert('请先上传文件之后再进行此操作！');history.back();</script>")
Response.End()
End IF
Co_recommend = "False"
IF Request.Form("Co_recommend") = "true" Then Co_recommend = "True"
Set MM_Recordset = GetRecordset("Select * from table_Commodity Where Co_name = '" & Trim(Request.Form("Co_name")) & "' order by Co_createdate desc")
IF Not MM_Recordset.Eof Then
Response.Write("<script language=javascript>alert('对不起,您所填写的商品信息已经存在！');history.back();</script>")
Response.End()
Else
SQLString = "Insert Into table_commodity(" &_
"Co_name,Co_cateID,Co_picture,Co_clicks,Co_factory,Co_createdate,Co_intro,Co_contact,Co_Website,Co_Email,Co_masterid,Co_recommend)"&_
" Values('" &Trim(Request.Form("Co_name")) & "','" & Trim(Request.Form("Co_cateID")) & "','" & Co_pictures & "',0,'" &Trim(Request.Form("Co_factory")) & "',#" & Now() & "#,'" & Trim(Request.Form("Co_intro")) & "','" &Trim(Request.Form("Co_contact")) & "','" &Trim(Request.Form("Co_Website")) & "','" &Trim(Request.Form("Co_Email")) & "'," & recorderID & "," & Co_recommend & ")"
Response.Write(SQLString)
GetRecordset SQLString
End IF
MM_Recordset.Close
Action=""
.....
<input name="Co_picture" type="text" id="Co_picture" size="50" value="<%=Co_picture%>"/>
<input type="button" value="上传文件" onClick="showUpload(this,'Co_picture','../uploadfile',10,null);" />
.....
Ⅳ 如何使用文件上传组件上传文件
你咋提问提到操作系统去了呢
是C#吧
protected string UpLoad(System.Web.UI.WebControls.FileUpload UP_FILE)//参数是一个上传控件
{
string photourl = string.Empty;
//上传文件
if (UP_FILE.PostedFile.ContentLength > 0)
{
//设定上传文件的保存路径
string strName = UP_FILE.PostedFile.FileName;
FileInfo fl =new FileInfo( strName);
//Response.Write(fl.CreationTime.ToString());
string[] strs=strName.Split('\\');
string strSaveDir = "file/" + strs[strs.Length - 1];
//取得文件名(抱括路径)里最后一个"."的索引
int intExt = strName.LastIndexOf(".");
//取得文件扩展名
string strExt = strName.Substring(intExt);
strExt = strExt.ToLower();
//if (strExt != ".jpeg" && strExt != ".jpg" && strExt != ".gif")
//{
// Response.Write("<script language=javascript> alert('文件类型必须为.gif、.jpg、.jpeg')</script>");
// return;
//}
//if (UP_FILE.PostedFile.ContentLength > 3000000)
//{
// Response.Write("<script language=javascript> alert('图片大小超过了限制')</script>");
// return;
//}
UP_FILE.PostedFile.SaveAs(Server.MapPath(strSaveDir));
return "上传成功！";
}
else
{
return "请选择要上传的文件！";
}
}
Ⅵ aspupload组件上传路径设置的问题
我有，可以限制上传文件格式，可是删除文件的数据库信息，同时删掉相应的物理文件。可以保存文件的上传格式，文件大小，文件名等等相关信息到数据库保存。不过……明天要考试，有空再发给你哦，记住哦，肯定给你的，因为是运用在我的网站里面的，我网站代码很多，你研究也很费劲，对不？所以我要有时间再整理出来你要的代码，再发给你，对不？
Ⅶ 有组件上传加水印

Else
