If you opened the image with a stream, or some object and you didn't close it, yes, you won't be able to delete it. However if you are only referencing it as a source for an image object in asp.net, that isn't really holding it. Either there is a stream holding it or some other program you use in your PC. If unsure, try to delete manually, if you get the same message, reset iis, and try to delete manually again, if it's deleted then you have something in your program that's locking it, otherwise another program is locking it.
If all else fails, may be asp.net doesn't have proper rights to delete it.

Is it possible to call a web service method from another web service? I am a beginner and know how to create a web service and to call a web service method from asp.net. But my client is asking me to develop a web service to call other web service. Please explain in details or if possible please provide me with some samples.
Thanks in advance,
Bala

Of course you can
A web service is a project, so you can simply reference your web service from your OTHER web service just like you did when you referenced the web service from the asp.net project.

Hi, good day.
I have a question about the checkbox in datagrid.
The problem is i have a datagrid in my page and i have 4 checkbox per row in the datagrid. I use the radio button to select the record and i can check the checkbox for certain specify action.
For an example, i select the record to be print in different type of report format. The checkbos is use to select which report format need to be printed out.
Did anyone can help me to solve this problem? Thanks..

what exactly is the problem which you are getting in that? As you can put all the checkboxes in the itemtemplate column of the datagrid and same with the radio button.

Hi.. my problem is in the datagrid i got 4 columns are chechbox. Each of the column with checkbox represent different type of report printing format( that is each column's checkbox will be redirect to the specify report page when the user checked on it). When user checked the checkbox, how i get to know the status on which report need to be printed out by the user.
Thanks..

when you want to know that which checkbox has been checked? Do you want to go to the server when user has checked any checkbox or after user checked the checkbox and clicks on some button?

yup.. user will click the "OK" button after checked the checbox on the selected record. User will be redirect to the page which the user have checked. If the user check more then 1 checkbox, user will be redirect to the report type page one follow another.

|
And what will happen if the user has checked for the multiple rows of the datagrid (ofcourse different options in the checkbox)?
Best Regards,

|
|
User only can select one row at a time because i use radio button to select the row.

Then you can use foreach loop to iterate through all the rows and then can find the checkbox and their value and do the operation as required.

Is it possible to keep the checkbox value and pass to another page? Because i need the checkbox value to perform another operation. Thanks..

No directly it is not possible but what you can do is you can store it in some session variable or if it is not big then can also be send through querystring.

how to write the code using query string? The value of the checkbox is which page the user will be redirect to. If use session, how the code looks like? Thanks.
Best Regards,
Pei Sun
|
|
|
|
|
suppose if you want to use session state then you can store the value like this:
Session["varName"] = "value what you want to store";
same way you can retrieve also:
string str = Session["varName"].ToString();
For querystring like this:
URL?varName="value what you want to pass";
and to retrieve :
str = Request.QueryString["varName"].ToString();

In the message, you failed to state the exact problem that you are facing.
Use TemplateColumn for the radio buttons and checkboxes. Then you can access those controls using FindControl() method of the datagrid cell.

Once you bind the checkboxes in the grid using item template or template column,
In print button_click u can access that checkboxes
i.e
1)get the row object of your grid
2)get the checkboxes reference
CheckBox cb1=rowobj.findcontrol('checkbox name');
-do- for 4 chkboxes
3)if(cb.checked)
{
write u r code here
}

can u provide me more deatails sample. Thanks..

I can not seem to figure out what the problem is with my code. (I
will post after my problem/question). If you perform a search of
categories in Horror, there are 4 titles that appear. I then click
on a title. The details for the title appear. When I perform
another search for a title, actor or director that exists in the
database it will search but the details of the movie I had previewed
stays on the screen. Any help is appreciated. Thanks, Terri Klepzig

 How in Asp.Net can you find the amount of time it took to generate the page? I see this sort of stuff on the bottom of websites all the time. Code or a link to a tutorial would be greatly appreciated

You can't, really. You can get the execution time of part of the generation process, but not the whole. However, that is probably what the others that you saw does anyway. What you can't measure is the compilation and creation of the page object, and the rendering of the page. The compilation takes about three seconds for the first page, and the time used for object creation and page rendering doesn't vary very much, so it's not very interresting anyway.
Get the current time as early in the page creation process as you can, like in the PreInit or Init event. Then get the current time as late as possible while you still can put anything in the page, like in the PreRender event. Subtract the times and put the result in the page.
