Hi, again me, I found one potential prolem to check the authorize, it displays the folloiwng informaitn, "The server is configured to be used to access the specified physical path pass-through authentication with a predefined account. IIS Manager can not verify whether the built-in account has access. Make sure that the application pool identity has Read access to the physical path. If the server is connected to a domain, and the identity of the application pool "Network Service" or "Local System" is to make sure that has <domain> \ $ <computername> read access to the physical path. Try these settings again." Do you think is this cause the problem? if so, then what does it mean exactly?

HI, thank you very much! I just repeat exactly as what you have introduced in your article "Deploying ASP.NET Websites on IIS 7.0" , the same error gives, that is to say, the web.config has problem, I can not understand at all. because I just create a default website based on ASP.net without doing anything. frankly speaking, my website has been ready several months ago, I just want to publish it, but I do not how to publish it. I really have no idea why it is not succeful. Could you please help me? what could be the reason? I really hate IIS. I am looking forward to your reply. thanks again.

I have one quite simple website made by ASP.net, visual studio 2005, the website is nothing but just display 'hi'. I just want to know how to us IIS for it. however, it gives the following error message: This configuration section can not be used in this path. This is the case when the section is locked at a higher level. The closure takes place by default (overrideModeDefault = "Deny") is explicitly or with a location tag with overrideMode = "Deny" or the Legacyeinstellung allowOverride = "false" set. anyone can tell me what is the problem? thanks!! I have translated from German, the original information is as follows: HTTP-Fehler 500.19 - Internal Server Error Auf die angeforderte Seite kann nicht zugegriffen werden, da die zugehörigen Konfigurationsdaten für die Seite ungültig sind.

actually, I have tried this way, it does not work, but as you proposed again, then I tried again, and I find that the object should be conveted into string first, then it works! i.e.: <img style="height: 80px; width: 65px" src="<%# Server.UrlEncode(DataBinder.Eval(Container.DataItem, "BookCover").ToString()) %>" alt="not available"/> OK, great, I have got lot of help from you! You are quit active in this area, hopefully, more help can be obtained from you!

Hi, Abhishek, I have one more similar problem, which I do not know who to deal with: similary, I have one image field bind to the book cover, which is saved as the file path in a database, once again, I found that if the file contains C++ then the image file can not be correctly bound to the image field. do you have any idea why for this case? <asp:TemplateField HeaderText="Book Cover"> <ItemTemplate> <img style="height: 80px; width: 65px" src="<%# DataBinder.Eval(Container.DataItem, "BookCover") %>" alt="not available"/> </ItemTemplate> </asp:TemplateField>

thanks, it seems that I need to learn a lot! there are many things I have not known!

I use the following format to redirect from a search input text, but I have the following poblem: when the input textbox (i.e. TextBox_Search.Text ) contains ++ or #, it results in wrong result: e.g if I input "C++", then search_text is not "C++" but only "C"; if I input "C#", then search_text is empty! this is maybe due to string problem, but I do not how to deal with these cases. protected void Button_Search_Click(object sender, EventArgs e) { Response.Redirect("~/BookList.aspx?search_text=" + TextBox_Search.Text + "&search_based=" + DropDownList_search_term.SelectedValue + "&display_content=booksearch"); } string search_text = Request.QueryString.Get("search_text");

I found that in ASP.net databind and SQL database, I have met often the problem: when the file contains some special signs such as C++,and C#, then it can not be found by databound control or wrongly displayed. anyone can give me one hint how to deal with this? thanks!

right, I have used this way!

I found that in my webpage, once the alert messagebox (as follows) is shown then some control styles (such as, location, font size and so on) are changed in a unexpected way. what is the reason then? anyone suffered this problem before? Response.Write("<script>alert(sth is here!')</script>");

really? if so, I am confused by this code. thanks again!

thanks, I see!

thanks, I see, but do you know string strHostName = System.Net.Dns.GetHostName(); string clientIPAddress = System.Net.Dns.GetHostAddresses(strHostName).GetValue(0).ToString(); gives also IP? or sth else? thank you again!! your article is great!!

I tried this code on my own PC, it shows the IP: 127.0.0.1 this is obviouly not right. This is not the right IP of my computer. I saw from internet, there are also others have the same problem. then some people suggest using the following code: string strHostName = System.Net.Dns.GetHostName(); string clientIPAddress = System.Net.Dns.GetHostAddresses(strHostName).GetValue(0).ToString(); but it shows the result as follows: fe70::8c3:258f:3f47:fd6b%12 this is IP?? do you have more comments on this? thank you again!!
