㈢ 為什麼我只能從c:單張上傳相片到百度雲
重新下載網路雲，安裝網路雲，你可以選擇上傳的路徑的。
㈣ 有一個C開頭的上傳圖片的網站網址是多少來這
是這個吧
c.imqqjs.com
我都是用這個上傳圖片，挺穩定的。
㈤ C證怎麼下載的照片怎麼上傳

㈥ 在C#中，如何實現上傳圖像的功能……
參考代碼如下：string filepath = FileUpload1.PostedFile.FileName;
string filename = filepath.Substring(filepath.LastIndexOf( "\\ "));
string fileEx = filepath.Substring(filepath.LastIndexOf( ". ")+1);
string serverpath = "C:/aa/upload/ " + filename;
string dbpath = "\\upload\\ " + filename;
if (fileEx == "jpg " || fileEx == "bmp " || fileEx == "gif ")
{
FileUpload1.PostedFile.SaveAs(serverpath);
Response.Write( "成功 ");
Image1.ImageUrl = @ "..\aa\upload\ " + filename;
}
else
{
Response.Write( "失敗 ");
}
string sql = "insert into gc_carno(id,carno,model,carphoto) values(100, ' "+TextBox1.Text+ " ', ' "+TextBox2.Text+ " ', ' "+dbpath+ " ') ";
OracleConnection conn = sda.getoracleconnection();
conn.Open();
OracleCommand cmd = new OracleCommand(sql,conn);
int i = cmd.ExecuteNonQuery();
if (i == 1)
{
Response.Write( " <script language= 'javascript '> alert( '添加成功 ') </script> ");
}
else
{
Response.Write( " <script language= 'javascript '> alert( '添加失敗 ') </script> ");
}
在資料庫存儲的是伺服器圖片的物理地址，數據類型是varchar型。
㈦ 怎樣從電腦上往8010c上傳圖片啊
藍牙，紅外，數據線。彩信。
㈧ C/S程序如何上傳圖片文件到伺服器
以文件形式保存在一個文件夾里,文件名用GUID方式命名
㈨ e251c上傳照片
要安PC STUDIO 才行 這樣手機的內存才能連接上
或者你可以先把照片復制到存儲卡上 然後在從存儲卡上移到電腦裡面去
㈩ 我在報名2級c語言，照片上傳時顯示javascript:_doPostBack("btnUpload")，是什麼問題，怎麼改
是javascript提交表單的機制，__doPostBack(eventTarget,eventArgument),eventTarget點擊的對象比如button，eventArgument是事件的參數，button的onclick事件轉化成HTML語言就是對應的__doPostBack(button的Name,''),javascript:__doPostBack('anp1','2')，anp1可能是換頁的，如果是頁面的話，就是anp1為頁面控制項，2為頁碼索引為第三頁，找後台的anp1控制項的SelectIndex_change後台事件
