So what do you guys think how should i copy the data. The problem is that I want to see if doc1 objects has been changed or not by comparing the initial state of the doc1 and storing in doc2.
i.e
if(doc1.body.innerhtml!=doc2.body.innerhtml)
{
MessageBoxshow("doc1 object has been changed");
}

By comparing the html string? Why do you need a second COM object to compare strings?

Thanks for replying but it doesn't work by comparing the two strings may be iam doing something very silly, that's why i am trying to create two object. The 2nd object holds the 1st object inital state data.

I don't understand. You posted the code showing that you wanted to compare the two strings
netJP12L wrote: if(doc1.body.innerhtml!=doc2.body.innerhtml)
All I am saying is that you don't need another COM object to compare strings. If you don't know what your requirements are I certainly don't. If you ever figure out what the requirements are maybe you could post them and someone could help you.

I am trying to put together a quick and dirty app, but have hit a problem and need a litle help!!
basically i have a DataAdpter and fill a datatable. This is then bound to a grid, and the user can edit the data (not add or delete records tho)
Easy so far!
Then they can click save and i call
_adapter.Update(_dataTable);
now if some of the data has been changed in the database i get an DBConcurrencyException. What i really want to do is prompt the user for each record that has changed by another app in the database, and ask if they want to force their values on the record or abort that record update, and continue with the rest. Can i do this, still using the _adapter.Update method? if not, whats the easyest (sp) way to do it
Many Thanks
Mark

after some digging, i have found the answer
adapter.ContinueUpdateOnError = true; will make sure it continues after an error
and
SqlCeCommandBuilder builder = new SqlCeCommandBuilder(adapter);
builder.ConflictOption = ConflictOption.OverwriteChanges;
Makes it a last in wins, which will do for my app.

Hi all.
I have a problem and i can't seem to solve it.
I have a DataTable with all the Data a need. From time to time i need to make a call to the DataBase to refresh the DataTable. I need to add/update/remove the rows from the DataTable comparing them to the rows that came from the DataBase.
How can i do that? I can add the new rows, but if some rows where deleted/updated in the DataBase how can i delete/update them from my DataTable?
|
|
|
|
|
How about just clearing the DataTable and re-grabbing the data from the database. since you're bring all the data down anyway, it would probably save some CPU time as well.

Thats right. But theres only one problem. If the user has scroll down the Grid and i clear the DataTable and refill-it then scroll will go to the first item in the list. Is there a way of avoinding that?
Thanks for your reply.

My file contains records which look like this:
EMPLOYEE001,M,20081105
First column is employee ID, second is gender and third is date.
I want to read this from a comma separated variable text file and think a regular expression is the way to do it. I do not want to create a dataset from the file.
Help much appreciated

To do what? You haven't asked a question, and a regular expression will not read records from a file.

Sorry for not being more clear. I will use a regular expression to validate my record I read from the .csv file.
Like this:
Regex regex = new Regex(expression);
string[] parts = regex.Split(record);
Sorry again

And you are basing that on? If you don't know how to use regular expressions, why do you think that's the way to do it?

Please see my answer above
Sorry, but I thought I wouldn't need to explain that I could get the record from the .csv text file.

I have done a code on 3D office. I would like to do it in interactive way which by pressing the arrow button, the object can be viewed from different perspective. However, my result come out with static image and my objects all disappear. The object exists if i doesn't include the Checkmovement function inside. I wonder what mistake i have done. Could anyone please kindly help me review my code and give comment. Thanks.

Why would anyone want to wade through over 400 lines of unformatted code to work out what you have done wrong? Try running in debug mode and see where things go wrong.

Agreed.
Reading the unformatted code is not easy, especially since you don't limit it down to what's important.

I would assume you've just got some bad math going on in the camera position calculations.
I would look at your values you're calculating for the following line of code and verify you're not moving the camera into a position/angle that is away from your 'office'.
Scene.SetCamera(sngPositionX, sngPositionY, sngPositionZ, sngLookAtX, sngLookAtY, sngLookAtZ);
Your initial values are:
sngPositionX = 0;
sngPositionY = 20;
sngPositionZ = 0;
sngLookAtX = 0;
sngLookAtY = 20;
sngLookAtZ = 50;
So, see if you're pointing your camera in the wrong direction.

Thanks to Andrew for kindly answer my question. Sorry to Ashfield if i have ask a stupid question but i have debugged it and it appeared no error. So, i just want to get what is wrong behind my logic. Anyway, thank you!

There are no stupid questions.
Regardless, by spending a little more time up front phrasing your question and making it easy to get a grasp of your problem, you'll find people are more willing to spend the time to answer you. It's just some helpful advice.
