Use the path starts from root directory. Something like /two/Default1.aspx and it can be accessible from anywhere within the site.

web.config identity impersonate - pwd in web.config [modified]

hello - i have three questions concerning impersonation.

(1) Not sure if I like to have password in the clear/web.config to do impersonation in ASP.NET

Example:

<br />
<authentication mode="Forms"><br />
			<forms<br />
    name="SomeWebApp"<br />
    loginUrl="LoginForm.aspx"<br />
    protection="All"<br />
    timeout="30"<br />
    path="/" /><br />
		</authentication><br />
		<br />
		<identity impersonate = "true"<br />
       userName = "MyBox\WEBAPPUSER"<br />
       password = "pwd"/><br />
<br />
<br />
		<authorization><br />
			<deny users="?" /><br />
		</authorization><br />

(2) Also, how can I grant right (by right click folder properties) to MyBox\WebAppUser so it can write/log to file under:
D:\Inetpub\wwwroot\SomeWebApp

Or should I just grant WRITE permission on the particular log file but then it means I'd have to pre-create the log file. tried couple things I hear perhaps I should grant permission on "Compiled directory" (or "Temporary ASP.NET files directory") of the asp.net app - I found it, it's under:
D:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files

I then granted permission on the folder - didn't seem to help problem (3) below. (But the dll's aren't in the temp folder)

(3) If I impersonate a non-Admin account, I get errors such as:

<br />
[FileLoadException: Could not load file or assembly 'Castle.Core' or one of its dependencies. Access is denied.]<br />
[FileLoadException: Could not load file or assembly 'Castle.Core, Version=1.0.3.0, Culture=neutral, PublicKeyToken=407dd0808d44fbdc' or one of its dependencies. Access is denied.]<br />
   System.Reflection.Assembly._nLoad(AssemblyName fileName, String codeBase, Evidence assemblySecurity, Assembly locationHint, StackCrawlMark& stackMark, Boolean throwOnFileNotFound, Boolean forIntrospection) +0<br />
   System.Reflection.Assembly.nLoad(AssemblyName fileName, String codeBase, Evidence assemblySecurity, Assembly locationHint, StackCrawlMark& stackMark, Boolean throwOnFileNotFound, Boolean forIntrospection) +43<br />
   System.Reflection.Assembly.InternalLoad(AssemblyName assemblyRef, Evidence assemblySecurity, StackCrawlMark& stackMark, Boolean forIntrospection) +127<br />
   System.Reflection.Assembly.InternalLoad(String assemblyString, Evidence assemblySecurity, StackCrawlMark& stackMark, Boolean forIntrospection) +142<br />
   System.Reflection.Assembly.Load(String assemblyString) +28<br />
   System.Web.Configuration.CompilationSection.LoadAssemblyHelper(String assemblyName, Boolean starDirective) +46<br />

These are dll sitting in the web app's bin folder under virtual directory and error goes away if I make impersonated account member of "Administrators", which is undesirable of course. Any suggestion? I tried add one dll in gacutil, that solve the problem for that one dll. Do I need to actually do this for ALL dll's? That's very troublesome. I suspect it has to do with assembly binding ... path probing ...

Thanks

Playing With The Club Starter Kit Again... [modified]

I've modified the Error.htm page for the application to include an image using the usual IMG tag. It won't display. It's a normal .jpg file, there's a copy in the /images folder, it's been officially added to the project, and the src is given as ~/images/myimage.jpg. It's inside a div with a corresponding CSS style class that specifies the size of the image and the visibility attribute as "visible." What the heck am I doing wrong here?

And while I'm on the subject, why is the Error page the only one in the project that is straight HTML with a .htm extension? Is that done to enable display when the ASP.Net app isn't responding?

[EDIT]

Okay, I've solved the first part. When a page has the extension .htm, references to outside resources are prefixed with .../foldername. When the page is suffixed with .aspx, a tilde will do.

Insert empty datarow into datatable

Hi all,

I am knowing how to insert datarow into datatable by using method below:

DataTable dt = new DataTable();   
DataRow myNewRow;   
myNewRow = dt.NewRow();   
myNewRow[0] = 1;   
myNewRow[1] = "johndoe" ;   
dt.Rows.Add(myNewRow);

But in my case, i have upto 20 columns for a row data.Then i don't want to use the For...Loop to declare each column's value. So, may i know its there have any others alternative to insert a empty row into datatable?

Note: Actually at the end, i will bound this datatable to a dropdwonlist.

any helps are welcome
Thanks in advance

regards
cocoonwls

Hi all,

I got a solution base on my case(in my case i want bind this dt to dropdownlist). In the dropdownlist control, firstly set appenddatabounditems to true, then add a empty items into collection. Then, at .cs just bind the data into that dropdownlist. Off course you have set the datatextfeild and datavaluefeild. Laugh | :laugh:

thanks for those view my question~

print customised footer on every page on client machine while printing

Hi coders,

Currently I am going through a bit complicated problem. It would be great if I get help from you.
The issues is, I have "print this page" button on each page on my site. Where I have called "window.print()". Now my client wants customised footer on that including his logo etc. So now, on that print button, I popup a window and pass the content to another predifed page with footer.
Its working nice if only 1 page print is their, but if content is big and expands to 2 or more pages then my footer is printed on last page only (Obviously). So, I wrote a code for manipulating the Registry Key for "Microsoft\\Internet Explorer\\PageSetup". Code is below:

string strPath = "Software\\Microsoft\\Internet Explorer\\PageSetup";
Microsoft.Win32.RegistryKey oKey = null;

/* The following lines of code takes care that error does not occur if registry settings are not at proper path.*/
oKey = Microsoft.Win32.Registry.CurrentUser.OpenSubKey (strPath, true);
if (oKey != null)
{
    oKey = Microsoft.Win32.Registry.CurrentUser.OpenSubKey(strPath, true);
}
else
{
  oKey = Microsoft.Win32.Registry.LocalMachine.OpenSubKey (strPath, true);
}

string strKey = "footer";
//object oValue = "&u&b&d";
object oValue = "test footer";
oKey.SetValue (strKey, oValue);
strKey = "header";
oValue = "&d";
oKey.SetValue(strKey, oValue);
 /* You can also get the value in registry by following line of code
    string strValue=oKey.GetValue (strKey).ToString();*/
 oKey.Close();

But, I think this will modify Server machine's registry value not client machine's.

Is their any other way to cop-up with this issue??

Any help will be greatful.

Thanks,

Correct. The only solution I can see, is to know where the page breaks are, and insert the footer accordingly.

Ouch!!! That will cause lot of coplexity. Specially if content have images, I have to mind image height and everything. Actually I thought of that before but for the same probelm as I mentioned, I refuse that solution.

I have also thought of one other solution that is to create word/pdf document (on click event of that button) on client machine and put footer on that. but that will look very ugly.(imagine clicking Print button, one document is being downloded on client machine).

Can I access client machine Registry by Javascript? I think thento It will cause permission problem to modify remote machine registry. Am I right?

Thanks for suggession Christian!!

determinte async postback trgger event

C. L. Phillip13-May-09 10:00

Let's say we have a ListView inside of an update panel. It has paging, sorting enabled and also has selectable rows. I was wondering if there is a way to determine way to determine which event caused the update panel to postback. So lets say selectedIndexChanged event fired, caused an async postback and now i can assign a callback only for when that event returns via Javascript.

I know you can call Sys.WebForms.PageRequestManager.getInstance.add_endRequest(EndHandler), but I believe that fires regardless of what event triggered the postback.

It's possible in code behind to get the control id of the async poster, for example:

ScriptManager current = ScriptManager.GetCurrent(this.Page);
if (current.IsInAsyncPostBack) {
    if (current.AsyncPostBackSourceElementID == myControl.UniqueID) {

    }
}

I'd be surprised if it wasn't available from the Sys.WebForms.PageRequestManager class, or in the event args from the client side.

Hi,

I have a menu on my web form. Each menu item has 25 subitems. its values are Production, jobTickets, configuration etc. My question is that when I click subitems Production it should show me page1.aspx and when I click on jobTickets it should show me page2.aspx. So how can I pass the values(production, jobTickets, configuration etc) to MenuItemClick method .

Why dont you use a sitemap and an asp menu or treeview to navigate your site?

Baffling behaviour with IE7 & Jquery

bVagadishnu13-May-09 9:18

Any hints on how to debug this scenario:

I inherited code which uses Jquery hoverIntent to swap images on left nav mouseover.

I open an .aspx page in IE7. The mouseover on the left nav changes the image showing in the center of the screen. Click on menu navigates to appropriate page.

I open the same page in IE7. The mouseover on the left nav changes nothing. Click on menu does nothing.

About 1 time in 15 the mouseover/navigation works.

View source in both situations reveals identical html.

Closest I could find is there is a bug in the jquery hoverIntent plug-in for IE7 on mouseout. The mouseout callback is an empty function.

Everything works fine in FF3

It turned out to be a race condition type problem.

The masterpage had script includes that performed set up functions in onready.
The aspx page needed to add a class to the body tag in the masterpage, also onready.

FF3 handled it. IE7 didn't.

I took the onready wrapper off the addclass code in the .aspx page and it works (so far)

OF course not. You auto generated them, remember ? You can define a template, but your template gets ADDED, you can't remove the autogenerated columns.
