Hi,
I need to Convert XML file into CSV file format
Pls forwad me the code for that in C# or vb,net
Regards,
sanjeev

I don't know about others, but I can only guide you to the right direction. I don't think that asking for the complete source code is a good idea.
I would:
1. Load the XML file into a table in a dataSet
2. Construct a new file on the disk giving it the extension .CSV
3. Loop through that table and copy each of its records into a new line of a text file by comma separating each column's content.
4. Save the file (close File streams)
5. Destroy dataSet
6. That's it
Hope this helps

Since Ms Excel can automatically load CSV files why don't you convert your XML file into a CSV one instead? (Now that I think about it, doesn't it load XML files automatically as well?)
Anyways, if you do decide to convert your XML file into a CSV one, take a look at these steps as they were suggested on the previous post:
1. Load the XML file into a table in a dataSet
2. Construct a new file on the disk giving it the extension .CSV
3. Loop through that table and copy each of its records into a new line of a text file by comma separating each column's content.
4. Save the file (close File streams)
5. Destroy dataSet
6. That's it
Hope this helps

I got a problem with a C# app trying to access files/folders on a LAN
When I try a Directory.Exists(foldername) it always returns false.
Directory.GetCreationTime(folder.Name) gives me a System.IO.IOException: Could not find a part of the path.
I can access all files on the network perfectly but just not with my C# app.
Any ideas on how to fix this?

Can you be a bit more specific on the way use for trying to access network files through C#? E.g. a sample portion of your code?

Polis

After some debugging etc. It seems that its a custom windows service thats trying to access those files (Service is setuped to use my user account details instead of local account).
Basically when I tried Directory.GetCreationTime(path) (C# App which is called by the services at certain timeperiod), it results in that error. I have an other C# app (with no ties to the services) and it works fine.
Any idea how to fix this?

Is your service running under the Local System account? THe Local System account doesn't have any rights to network resources. You have to go into the Services manager and chagne the account it's running under to one that has rights to the network files your trying to get at.

Yes , I have done that. It stills gives the same error. The user acount which the services uses has no problem accessing any network resources unless I use that C# program with the same services.

If the application works as a normal application, the account you THINK your using isn't the one your actually using for the service. Did you include the Domain in the username portion? Like MYDOMAIN\useraccount...

Yes I did that aswell, it even wouldnt allow me to register using only my username (so I did made that mistake). The code which is trying to access the files is a dll, if I am right its loaded into the memory space of the service so it isnt the app trying to access it.

Hey!
I am displaying everything that comes in on the serialPort in a RichTextBox.
I have made a stress test program that sends as much as it can to my program through the serialPort.
The Performance startas out as normal, but after a while I notice that it goes from 10% up to 100% of CPU usage in about 2 min (depending on the threshold of the RecivedDataEvent(in this case 32 bits))?
On the RichTextBox i am using a scrool to bottom code like this:
<br />
rtIncomeLogg.AppendText(inData);<br />
<br />
if (AUTOSCROLL)<br />
{<br />
rtIncomeLogg.HideSelection = false;<br />
rtIncomeLogg.Select(rtIncomeLogg.TextLength, 0);<br />
}<br />
I have tryed do unhook the rtIncomeLogg.AppendText(inData); so no data is appended to the textbox, and by doing this it lays on 10%-15% CPU usage.
I thougt that maby the textbox is becoming full and have problem appending text at the bottom, so a tryed to remove data so the lenth not exided 5000, but i dident got this to work(used the richTextBox.text.remove(0,nrOver5000).
I realy need to display data little by little.
Do you got any ide how to fasten this up? Maby clipboard is an ide? Maby regular textbox is betther then richtextbox?
Best Regards
Jimmy

The RichTextBox definitely isn't the best choice for this kind of output!
You could use a plain TextBox or, what I'd consider the best solution, a ListBox, where you can add entries, make the last entry visible and remove entries from the beginning of the list without too much trouble.
That way you can keep your logging entries to 100, 500, or whatever suits your needs.

Thanks!
I will test the plain TextBox. The ListBox would be some problems for me, the input on the serial port is not readed by row but read exisiting, this means that the rows will be strange.

I bet your RecivedDataEvent comes in through a non UI thread. You must not call AppendText or for that matter any method/property at all on the textbox from within that thread.
You need to call BeginInvoke or Invoke to marshal the call to the UI thread. Have a look at http://www.codeproject.com/useritems/begininvoke.asp[^]. It explains why you need to do that and also tells you how to use BeginInvoke.

Senthil

Yes i am using Invoke, i know that only the creating thread would be operating on the object/control.
I have no tested the plain textbox and its MUCH faster it semes like, but it also uses alot more CPU.
now its starts on 50% and it increase a little.
I will run more testst.
The problem with plain textbox simes to be that it is not using the \r\n propperly? insted it becomes a square??
Is there any setting for this? in richtextbox this works fine!
Best Regards
SnowJim
