Hi,
Ok my database sheme I use is XML, i am trying to populate the data in a treeview control but it gives me unhappy results.
Would it be easier or better by using an Access database rather than XML?
ok ine more question sorry, i have seen many times before a couple of application that store information in a file where they have their own extension. for example storing information in a file database like databse1.dat or smth. How do people do this or is this not C# at all?
Thanks guys
Regards

If you use the System.IO namespace to writ binary data, you can write any byte sequence you want, and call it whatever you like.
I doubt that moving to Access will, by itself, change how the tree control behaves.

Hi,
Thanks for the reply,
ok im using a binary file now to store my data and it writes perfect. but i have a problem with reading the data.
basically every line in the dat file is one record. how can i read only a specific line and retrieve those values?
Is it possible to populate a treeview control from a .dat binary file?
Thanks

You could tag the line with some string that you are pretty sure will be unique and then process the file line by line looking for that unique string. When it finds the line, parse the line into whatever format you require.

that wouldnt work really because i use a binary file not a text file so you cannot process line by line.
i have changed my mind am gonna stick with xml its alot better 
thanks for ur helps guys did learn alot though yay

It shouldn't matter whether the file is binary or not. When you read the file into memory it has to be parsed into a non-binary format in order for it's elements to be used by the program that is reading it.

Thank you,
It didn't work when i used the System.Diagnostics.Process.Start("IExplorer", "http://www.paologios.com") but it did work when i used System.Diagnostics.Process.Start("http://www.paologios.com") and it uses the default browser.
Thank you for you time.
Enjoy your day.

Never assume that the user is using a specific browser. Just open the url, and the default browser will open it.

hello every one !!
i have one problem i need to write a windows service that creates a folder and then on that folder i have a filesystem wathcher class to see if the file is created if created then move a file to remote computer. when i had hardcoded the folder to find file like c:/myfolder then i implemenetd filesystemwathcher on myfolder it worked fine now i have a case where i need to create a folder i.e my folder so that i can implement a file system watcher on any folder that is created on runtime.
to be short and precise i just want to create a folder(directory) by windows service not windows application.
any help would be greatly aprrecaited. happy windows servicing

If you run the service as user "LocalSystem", there a number of things you cannot do, by default (e.g., access a disk that is mounted as a network disk). The reason I mentioned default is because if you modify the default system policies you might overcome a number of these limitations.
You could run the service as an Administrator user. Then you would have access to doing pretty much anything you want.

hi
i want to ask that if there exit any function through which we can rotate image in c#.
i used the functions
rotateTransform( , ,)
and
RotateAt(, ,)
but the problem with these functions is that it create multiple data of the that image
i want to rotate the text from the image
thanx in advance

It creates a copy, yes. You can also set a rotate transform on your Graphics object, and so render the bitmap rotated, without ever rotating it.
s4_sabahatf wrote: i want to rotate the text from the image
You want to render text that is rotated on an image ? Well, you just need to set the rotation and translation on the graphics object, and you can draw your text that way.

ya i m using the graphics object by overridng the paint method but still it creates mulipte copies
then what shud i do??
|
|
|
|

I'm not sure what you mean by 'multiple copies' ? Do you have a memory leak ?
You can't rotate an image in place, you can't rotate it without making a copy. Doing it in your paint method makes a copy direct to the DC, and so costs nothing.

no no !!i dnt mean that for memory
let me expalin u
suppose i hav a image having text "SIg"
when i apply roation to that image it writes multiple times "Sig" "sig" on same image.it make partitions of that image .which creates problem

OK, that's because your code is wrong, obviously. Post your code.

now i solved my poblem by using DrawImage method,but now i m suffering from another problem that how will i change
g.DrawImage(, ,) into bitmap?
|
|
|
|
|
Build the graphics object from a bitmap ( Graphics.FromImage ), then call that method to draw onto it.
