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.
|
|
|
|
|
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.

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.

I think rather than GridView, Use Repeater Control .
|
|
|
|
|
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.

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
$@N@

|

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 !!!

Hi all,
I have a XML files that looks like this:
...
<dataset>
...
<p x="-0.979248" y="-0.00141319" />
...
</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.
|
|
|
|

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.
Regards
Sebastian

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...
<p x = "-0.975586" y = "0.000274252"/>
<p x = "-0.975342" y = "0.000164965"/>
<p x = "-0.97583" y = "0.000365295"/>
<p x = "-0.97583" y = "0.000365295"/>
<p x = "-0.974854" y = "-1.00148e-005"/>
I'll skip the regex and find the position fo "y = " and "/>" and grab the string between those positions.

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
Regards
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.

The error seems to be that the Column 'DistanceCovered' does not belong to table Table1 but there doesnt seem to be any mention of this column in my code any where. Have not checked the IIS logs will find out how to and see what info that gives me.
Thanks for your reply

Must be in there somewhere, in the FillPlayerMaxMinAverage method.
|
|
|
|
|
as you think this seems that you have a problem on your code, trace your app and find the problem

The problem is i have spent the last ten mins trying to get the same page to crash again and its running perfect now its doesnt make sense, the method mentioned FillPlayerMaxMinAverage does have statName as a param which may have been set to DistanceCovered but it just will not crash again, the page seems to be fine now so im just waiting for the next crash 
I managed to find the IIS logs, they are very messy, is there some less complicated way to check them ???

Thanks for ur replies guys....
I managed to find that one "Distance Covered" bug buried deep in the code and got it sorted now but the app is still crashing regularly, i have noticed that the majority of the crashes are happening in the Data Access Layer objects when they try to interact with the db. This is the most common crash i am seeing in Event Viewer. But the prob is this method is run regularly and only crashes sometimes.

I also have an application that I am supporting which becomes unstable / crashes. I was using the windows performance monitor and watching the .NET CLR Memory Total committed Bytes. The memory would just climb higher and higher and eventually the system would crash. I then looked into the Event viewer and we found error messages that lead us to the conclusion that there was a memory leak in one area of the application. The vendor fixed the leak and the system is more stable.
Start with monitoring the memory on the IIS server and check the memory usage, you may find a correlation between memory usage and system stability.
