If you need infos about the file from the server, you have to create your own FileInfo-class containing the properties you need.

<br />
public class MyFileInfoClass {<br />
<br />
   public Name { get; set; }<br />
   public FullName {get; set; }<br />
<br />
}<br />

Just create this object before you return the result of your method and fill the properties using the FileInfo on your server.

Btw. if you want to read the content of the file you have to transfer the file and not the FileInfo.

You can not use FileInfo in your result because it is not deserializable. What I suggested was that you create your class containing some properties of FileInfo you want to transport through the wire. But pls do not use the FileInfo-Type within the result, it will not work.

Rich text editor and master page?

ASP.NET has nothing to do with a rich text editor. Checkout free products like tinymce[^]

First of all there is nothing relation with Rich Editor control and master page. It can be placed in any content pages , so can easily displayed on master page.
You can Check for
fckeditor[^]

Or even if you search in Codeproject , there are some Excellent Java Script Editors available.

Hi,

sounds like the user does not have the permission to save the file. Check which user is editing the form and if this user has write-permissions in sharepoint.

I am ADMIN of the site and i have full access on it.
And I have created a service account which is used to impersonate the users, hence its not necessary that user has write access or not.

Re: An exception thrown while accessing local file

SeMartens13-Jan-09 2:37

Well, maybe the service account is used to store the file. Where will the file be stored: at the server or at the client pc? Did you checked the event log (security and application)? The description of the error in the event log will contain the user who will be used to store the file.

VisualStudio 2005 Is it possible to split Gridview column into multiple columns.

Is it possible to split a Gridview column into multiple columns.

That is one data column arranged into multi columns.
Say my data is AAA BBB CCC DDD EEE FFF GGG HHH III and I want it arranged

as so
AAA DDD GGG
BBB EEE HHH
CCC FFF III

instead of
AAA
BBB
CCC
DDD
EEE
FFF
GGG
HHH
III

as automatically produced.

Questions: Are there always nine columns or fields? Do you always need them in a 3x3 pattern? If so, I would not use a GridView. Assuming the data comes one row at a time from an ADO dataset or datareader, I would fill an asp:table dynamically, copying the data into dynamically created labels.

Someone's gotta be the last to know, but why is it always me?

Yes I reckon the only way to do it is use ADO dataset or datareader.

I just thought it might be possible to have one DATA field split into more than one GRIDVIEW column. The 3x3 pattern was just an example it could be any number of columns. Thanks.

ASP control hiding problem and DetailsView Paging

Hello,

question#1:

i have designed my master page in which there is an image(image1) on which i have added 4 imagebuttons, now when i add any other control to my page then any or all of these imagebuttons are hiding behind the image1...
may i know the reason ??

question#2

OK. You dont have to do that way. This is not Windows Forms. So just create a Table or on the < td > where you have placed your Image. set your "Image" as the "BackGroundImage". and then put your other "ImageButtons" on that Table or < td >. You can do this by using Overlapping < div >s, But it will not be displayed correctly over different browsers. So just go with the first option.

Question 2 ??? Comming soon !!! Smile | :)

Find highest XML value in

Hi all,

I have a XML files that looks like this:

...
<dataset>
...

...
</dataset>
...

I need to find the highest value of y. The files have 100 000 rows so it should be reasonable fast. But any suggestions are welcome.

Re: Find highest XML value in

SeMartens13-Jan-09 1:32

Hi,

first of all i wouldn't use an XML-class to load the dataset, this will be propably to slow. Try to use a stream to read the file line by line. There you could extract the y-value using a regular expression, or if all values have the same length (y is at the same index in every line) access it by its index. Then store the highest y-value somewhere and compare every y-value with this one. If the current y-value is higher overwrite the stored value.

This algorithm has a complexity of O(n). If you are using multiple processors you could think about splitting the file in two or more parts and use threads to accomplish the task.

Hope this helps you a bit.

Ah, OK. This was my first idea to solve the problem. But being an "old style" .net programmer I thought there was a more effective built in way to do it.

Stream and loop, simple enough...







I'll skip the regex and find the position fo "y = " and "/>" and grab the string between those positions.

ASP.NET 2.0 App Crashes

Hi All,
I have a database driven web app written with C#, Asp.NET 2.0 and uses an SQL Server 2005 back-end. The app usually crashes at least once a day but some days does not crash at all and others it crashes much more often, its like it gets stuck in a loop of constantly crashing. An iisreset fixes the problem so is it safe to assume its iis that is the problem but i really need to find out what the cause of the crash is so im just looking for some advice as to where to start, are there some tools i can use or whats the best way to go about this. Any help or advice would really be appreciated

Tim

Have you checked the event log on the server for some indication of what is causing the crash? Also check the IIS log files.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
