Howdy,
I have had a web site running for some time now and I am constantly having issues with the statement User.IsInRole ("somegroup") returning a false value. It does not always happen but often the user is a memeber of the group which membership is being tested but the statement returns false. The application makes decisions based upon the return value and then the user does not have proper access to certain functionality within the site.
We normally have to stop and start the application pool on the iis server. Is there anything I am doing wrong?
thanks
Patrick

Hi,
I need to check the date changed, if changed i need to execute a snippet for first request after date change and for further requests another snippet executes.
How do i check the date is changed? and execute snippet for first request only?

Look at Validation[^]
you can run your validation on the client side too. If you are looking only date changed events then look at this[^]

Hi Friends,
I am looking for the C# code to place one image on another image. My requirement is exactly like the following link.
http://photofunia.com/
When user browse and select his image, it has to be adjusted on another image. Please provide me if you have any sample code or if you know any third party controls and codes which provide these kind of functionality.
Thanks in Advance
Regards,
Malleswar

There is not a piece of code that does this. Perhaps there is a third party that makes it simple, but its pretty simple to do it from scratch without any extra controls.
Its actually a combination of 'photoshop' techniques and code. You do actually have to layer two photos on top of one another however in a rendered code page. You use the standard DIV tags and then layer them via the absolute positioning, setting the z-index of two tags to force one behind the other. The top most photo needs to be a GIF that has the sections 'cut out' and made transparent where you want the underlying photo to 'show through'. You will need a tool like Photoshop to accomplish this part (and its really the hardest part of it all). Its an old, and simple technique.

Thank you for the reply.
Please provide me some links where I can get sample codes or third party tools for this.

Hi Guys,
I've got a section on a master page that is visible when logged in. It contains a link to click to log out, which runs the following code
Session.Abandon();
Response.Redirect("~/default.aspx");
However, on the default page, the Logged in section is still visible with the log out button, and i can still access the secure areas without authorization. (Code behind still hit, so it's not cached).
What else do i have to do to get someone completely logged out? :S
Regards

it is better to use Session.Remove("AuthKey") and check the "AuthKey" from Master page..
sometimes Session.Abandon fails to clear current session variables completely.

Hi all,
I have a problem with that instruction: For Each f In IO.Directory.GetFiles(sDir)
sDir = "R:\Temp" for example.
When I use that on a local directory on the C:\ driva it works ok, but when I try to use that on the network with a mapped drive (example: R:\Temp) I get the error: System.IO.DirectoryNotFoundException: Could not find a part of the path R:\Temp
Can you help me?
Thanks!!!!

use complete UNC path rather than your map drive path. IT will solve the problem
Abhishek Sur
|
|
|
|
|
When I use the complete UNC (for example: \\MyServer\Data\xxx\ ) I have a new problem: System.IO.IOException: Logon failure: unknown user name or bad password.
Is there any other way of listing the files on a network drive?
|
|
|
|
|
Finally I solved the logon problem with those lines of code in the web.config
<authentication mode="Windows">
<identity impersonate="true">
It works ok with thw complete UNC.
Thanks for your help!!

Can you explain your solution with a bit more detail about the changes to the web.config?
Thanks,
Patrick
|
|
|
|

Yes, I added this lines of code to the web.config so the denny access message is solved:
<br />
<authentication mode="Windows" /><br />
<br />
<identity impersonate="true"/><br />
<br />
Now the directories are listed ok in my code:
<br />
For Each f In IO.Directory.GetFiles(sDir)<br />
Dim myList As New ListItem<br />
If f.EndsWith(".xls") Then<br />
Dim intPosicion As Integer<br />
intPosicion = f.LastIndexOf("\")<br />
myList.Text = f.Substring(intPosicion + 1)<br />
lstPaths1.Items.Add(myList)<br />
End If<br />
Next<br />
Here I list all the filenames that ends with .xls and put it into a listbox.
Did you understand now?
Sorry english is not my language..I speak spanish.

Good Afternoon
My Application is Structured in a Way that before you login you must First Select a Database. Now i have one page that i want to change the Connection String Database name.
I have this function that get called on page load
public void UpdateConfig()
{
CommonFunctions obj = new CommonFunctions();
String strKey = "NEWDT";
String StrDatabase;
if (Session["ActiveDatabase"] != null)
{
StrDatabase = Convert.ToString(Session["ActiveDatabase"]);
}
else
{
StrDatabase = "oDirectv3";
}
String strValue = @"User id=sa;Password=abacus;Server=LOUWTJIE\SQLEXPRESSDatabase="+StrDatabase;
Configuration objConfig = WebConfigurationManager.OpenWebConfiguration("~");
AppSettingsSection objAppsettings = (AppSettingsSection)objConfig.GetSection("appSettings");
if (objAppsettings != null)
{
objAppsettings.Settings[strKey].Value = strValue;
objConfig.Save();
}
}
On the Development site it works well. But while still debugging the code, checking if its doing what i want, There is a point where it has to save the changes
objConfig.Save();
The Part will execute and message box will appear asking me if i really want to save the changes made, i will save yes and everything will be fine. But if i don debug it , it gives an Error that says
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
How can i do this and Suppress this dialogs
Thank you

You're going about this all wrong. You cant possible update the web.config for every different session - the reason it works in development is because you are the only session. Once this goes into a multi-user environment I cant see how it would operate sucessfully.
I have a similar issue in an app I am writing, and I configure using separate connection strings in the web config and make a decision which one to use at run-time based on the user's settings.
