该功能通过以下方式调用:
myChart.gChangeBarColour(1, "#000000");
这有效:
// Changes bars colour
this.gChangeBarColour = function(gBarID, gBarColour) {
if (gBarID <= this.gData.length && gBarID >= 0) {
document.getElementById("gBar" + gBarID).style.backgroundColor = '#000000';
}
}
但这不起作用:
// Changes bars colour
this.gChangeBarColour = function(gBarID, gBarColour) {
if (gBarID <= this.gData.length && gBarID >= 0) {
document.getElementById("gBar" + gBarID).style.backgroundColor = '" + gBarColour + "';
}
}
控制台完全没有错误!有任何想法吗？

gfx.DrawString(
thisTempLabel.LabelText,
new System.Drawing.Font(
thisTempLabel.LabelFont,
(float)thisTempLabel.fontSize
),
Brushes.Black,
new PointF(thisTempLabel.x, thisTempLabel.y)
);
问题是我的用户在PX中选择字体大小,并且System.Drawing.Font需要EM大小.我不知道怎么解决这个问题!
我可以使用像素渲染文字吗？
public enum WebWizDateFormat
{
DDMMYY,
MMDDYY,
YYDDMM,
YYMMDD
}
public class WebWizForumUser
{
public WebWizDateFormat DateFormat { get; set; }
public WebWizForumUser()
{
this.DateFormat = WebWizDateFormat.DDMMYY;
HttpContext.Current.Response.Write(this.DateFormat);
}
}
这有效,但是当我响应时,它需要以"dd/mm/yy"的格式出现,我该怎么做？
public static bool CheckLogin(string Username, string Password, bool AutoLogin)
{
bool LoginSuccessful;
// Trim inputs and verify lengths
Username = Username.Trim();
Password = Password.Trim().ToLower();
// Get the associated user records
DataClassesDataContext db = new DataClassesDataContext();
var q = (from User in db.tblForumAuthors where User.Username == Username select new
{
User.Password,
User.Salt,
User.Username,
User.Author_ID,
User.User_code,
User.Active,
User.Login_attempt,
User.Last_visit,
}).SingleOrDefault();
// Invalid details passed
if (q == null)
{
LoginSuccessful = false;
}
else
{
// Increment login attempts counter
int LoginAttempts … // Insert new record
ArtworkingDataContext dc = new ArtworkingDataContext();
tblArtworkData NewRecord = new tblArtworkData()
{
dateCreated = DateTime.Now,
templateID = TemplatesID,
userID = UsersID
};
dc.tblArtworkDatas.InsertOnSubmit(NewRecord);
// Set new values
this.Loaded = true;
this.ID = NewRecord.ID;
this.DateCreated = (DateTime)NewRecord.dateCreated;
this.TemplateID = (int)NewRecord.templateID;
this.UserID = (int)NewRecord.userID;
}
当我设置新值时,ID不需要转换,但其他人都需要转换,否则我得到:
Cannot implicitly convert type 'int?' to 'int'.
我已经厌倦了投出所有返回的数据,我做错了什么？为什么ID不需要演员？
对于 <input type="password" />
在ASP.net中:
PasswordField.text = RawPasswordString;
这不起作用,但可以通过以下方式规避:
PasswordField.Attributes.Add("value", RawPasswordString);
我这样做,所以当登记表失败,他们不需要,如果他们是有效的重新输入自己的密码,这让我很烦,在一些网站上没有尽头.我们有一个需要服务器验证的CAPTCHA字段,所以当这个失败时(最有可能失败的字段),我不希望它们输入正确的字段,但是密码因为清除而失败,这意味着它们必须输入CAPTCHA again.
有什么安全原因,如果这个页面是在HTTPS上就可以了吗？如果它是在带有nocaching的HTTPS上,我还应该注意什么呢？
如果我将登录用户重定向到我网站上的非SSL页面:
Response.Redirect("http://www.mysite.com/page.aspx");
但是母版页有代码:
if (IsLoggedIn)
ForceSSL();
其中将用户重定向到:
Response.Redirect("https://www.mysite.com/page.aspx");
在重定向和第二次重定向之间,是否有从客户端传输到服务器的不安全数据？

与我的其他问题相关:
数据设计
假设我有一个标签表:
tblTags
-------------
TagID (int)
Name (string)
还有两个内容表:
tblBlogs
-------------
Anchor (GUID, Primary Key)
BlogTitle (string)
+ More custom fields
tblTutorials
-------------
Anchor (GUID, Primary Key)
TutorialTitle (string)
+ More custom fields
还会有更多带有锚点的表格,它不仅仅是2.
然后将标签与上述实体相关联:
tblTagAnchors
-------------
TagID (int, Foreign Key)
Anchor (GUID, Foreign Key)
我的问题是,一旦我建立了博客和教程与特定标签的关联,有没有办法编写一个查询来返回带有特定标签的博客或教程？无需对博客和教程进行单独查询？
主要用途是搜索,类似于(伪):
select from tblBlogs and tblTutorials where the GUID exists in tblTagAnchors where tagID = 5
for each record returned
if record from Blog
response.write("<a href=blogView.aspx?ID=" + recID)
else if record …sql database-design guid foreign-keys foreign-key-relationship
