It will only get set to 0 when the web server is restarted but when the page is reloaded.

Hi HarrisonB,
The hit counter should never be reinitialized to 0, even when the server goes down. It should read its value from some data store where a start value could be set (<> 0) at the beginning.
I think I can find some code where a xml file can be used. I will look it up and give you an answer as soon as I can.
Thanks for your time.

Good morning, most of my work is generally client server so some of the basic ASP.NET questions are a pain for me, so forgive me if this is stupid.
I am trying to load an image on the event of clicking a cell in a gridview. The gridview has a button and I am calling the RowCommand to load the picture. The field for the image name is in the gridview, the code looks like this (Basically)
protected void gvRecords_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "View")
{
Int32 rowIndex = Convert.ToInt32(e.CommandArgument.ToString());
string path = @"Images/Foo/images/";
string fileName = gvRecords.Rows[rowIndex].Cells[7].Text;
imgMyRecord.ImageUrl = Server.MapPath(path + fileName);
imgMyRecord.Height = 250;
imgMyRecord.Width = 250;
}
}
I have tried a static reference in the Mappath, but can't get the image to load. The possible caveat to this is that the "Images" folder referred to above is located on another server and is a virtual directory pointing to a UNC path. So I added the Virtual folder in the app folder pointing to \\server\folder.
Where is my issue? Is the setup of the virtual folder wrong or am I just plain old doing it wrong? Or both?

Examine the HTML source of your page and see exactly what ImageUrl is being created, debug from there.

I guess your css is not applying properly. Did you tested with all browser ?
If you are using FF, then install FireBug and test the CSS and all tags, or Copy the View Source of pages first time and then compare with second html code.
You will get to know the cause.

I would say this sounds like a session timeout.
Try to set a shorter time of period per session in web.config and try to confirm my suggestion.

Hello, On my local Dev machine I have developed a .net 3.5 (c#) web project (File System) and created the sql server 2005 objects i.e. tables. stored procedures, etc. All works fine. I have copied the database onto the Dev sql server. Now I would like to place the web site onto the dev server. Where do I start and what needs doing. Notice that I have developed the project using File System.
In addition, note that the .sln file is not present in the folder where I have the .cs and .aspx files.
Thanks

Hi To All,
I am having a requirement to get the database values into an array list using javascript.
Can any one suggest me

Using JavaScript alone? You can't. Use Ajax or scriptable web service to access the database from your JavaScript

Hello all,
I am developing a site using ASP.NET 3.5 using the default (English) language. I have a drop down button somewhere on the page which has two options English and Arabic with a lable that says Select a language you wish to view this site with.
Please how do I make this functional (i.e to change the site content to the selected Language)?
Thank you all for your usual assistance.

This is called localization. You need to use Localization features of ASP.NET.
Here is few startup article for you.

I have a question about defining a foreign key relationship on the same table.
will cascade property work on the table.
Thanks and regards,
Amit Patel
|
|
|
|

Hi Amit,
To create a Foreign Key, you must have a corresponding Primary Key in another table else not on the same table. The cascade on update option (if turned on/selected) automatically updates the foreign key as soon as you change it's primary key in the primary table.
Are you clear with this explanation? If yes, don't forget to mark it as a Good Answer.
Happy programming!

We can create primary and foreign key relation in same table that is what i already tried but on delete cascade property is not working.
Thanks and regards,
Amit PAtel

First of all, which database do you use?
They all handle such foreign keys (they are called self-referential) indifferent ways.
