Hi,
I got the answer . Thank u
I Modified the code a little :
DirectoryInfo df = new DirectoryInfo(@"C:\Inetpub\wwwroot\Sample\images");
foreach(FileInfo f in df.GetFiles())
{
string p = f.FullName.Replace("images", "New Folder");
File.Create(p);
}

ysunil_74 wrote: string p = f.FullName.Replace("images", "New Folder");
File.Create(p);
That just creates an empty file in a different location  and will also cause interesting side effects if the filename has the string "images" in it.

What prevents you from iterating through the list of files returned through .GetFiles()?

I appreciate your post but it didn't answer my question yet.
I'll be more specific, I'll tell you exactly what I've already done and what else needs to be done.
(if it's necessary: I use VS 2008)
I created a solution named "Shehakim".
in this solution I added two projects:Windows application named "Shehakim" and ASP.NET Web Service Application named "AppSevices".
in the AppServices project I configured roles and users etc. at VS Menu>Projects>ASP.NET Configuration.
then in Project Properties>Web>Servers>UseVS...>I chose the deployment destination of the service to port 55438 and Virtual path /AppServices.
then,
in the "Shehakim" project properties>Services I chose "Use Forms Authentication" and I supplied this address in the fields: http://127.0.0.1:55438/AppServices.
now,
what I want to do is to create a login form (A windows based form) in the AppServices project so I can call this form from many applications, and causing the "Shehakim" project react correspondingly to the users authorization in the AppService.
thank you so much for your time!

I am attempting to determine at run time what the maximum file size is that can be written to a particular location (for example, if using FAT32 file system: ulong maxFileSize = Math.Min(4GB, AvailableDiskSpace)). I am currently able to find how much disk space is remaining using the WinAPI call 'GetDiskFreeSpaceEx', but I cannot figure out how to get the max file size. So far, my only thought is to make a call to the WinAPI method 'GetVolumeInformation', then take the resulting file system, and do a table lookup to discover this max size. Can anyone either (1) inform me of a better way of doing this, so I don't have to rebuild anytime a new file system comes out, or (2) let me know the strings that can currently be returned by 'GetVolumeInformation' so I can lookup as many different FS as possible? Thanks,
Sounds like somebody's got a case of the Mondays

Hi Jeff,
first of all, I don't know. I do have some code that tries to clear a small partition (FAT)
by writing then deleting one new big file, but occasionally this throws an error,
probably because the new directory entry itself may need an extra sector (or even cluster).

Yeah, I havn't found anything either. I just went to Wikipedia and copied a bunch of file systems they had listed with max file sizes, then made a switch statement checking if the string matched any of those names. I know I have the big ones for windows (since 95), which presumably will prove to be sufficient since I am using the WinAPI to get the values. Anyway, if you or anyone else comes up with a better way, please let me know. Thanks,

I have a simple question. How can I find out if a drive is local or mapped and if network mapped what the actual network mapping is? I am using a FolderBrowserDialog to retrieve the path string and need to make sure the path is converted to actual path and check to see if the path is on a removeable device, local hard drive, or network path. I used to be able to this in C++ with API calls (it has been years since I tried), and C++ is not C#.
Thanks,

You can invoke API calls with C#.

Hello
I have a datacolumn that uses an expression to sum other columns, for example i have 3 datacolumns: count1, count2 and count3.
A 4th column "total" uses the expression:
"IsNull([count1],0) + IsNull([count2],0) + IsNull([count3],0)"
Which works fine if any one column value in the row is null. However if all 3 columns have null values, the 4th column will be 0. I want it to be null. See example below.
|count1|count2|count3|total|
| 3| 2| 5| 10|
| 12| | 3| 15|
| | | | 0|
for that last row i would like the total value to be blank rather than 0. How can I achieve that in the expression?
thanks
Yann

I found the solution
expression should be:
IIF(IsNull(Count1, -1) = -1 and IsNull(Count2, -1) = -1 and IsNull(Count3, -1) = -1, null, IsNull([count1],0) + IsNull([count2],0) + IsNull([count3],0))"
the first part of the IIF statement checks that all 3 count columns are null and returns -1 if they are. If all three conditions are true then the expression evaluates to null. Otherwise it totals up the value.

There is a much more simple way to do this. Do your math, and if it equals 0, set the last column to DBNull.Value

Hi,
I have a variable which contains file path called filename and I use this variable to start a process like this: Process proc = Process.Start(filename); If I pass path to a text file then everything work well, but if I create a shortcut for that text file and use it to start a new process, the return value is null. Why does it happen? Apart from that for some executable files the return value is also null. I've checked msdn and according to it null is returned when there already exists same process but it's not the case.
How can I retrieve the process started in this way if the return value is null? Do I have to use winapi?
Thanks

Not every process returns a value either.
Launching a shortcut just doesn't return a value. You can launch the .EXE, or whatever document, directly and get the return value (if there is one!), but launching through a shortcut drops the return value.
There is no way to retrieve the return value if the one you get back is null.

I've developed a pretty robust app as one of my first projects. It's a windows app in C#. I'd like to know a little more about how Visual Studio compiles everything, and what all these resource files are..etc. I guess I expected everything to just compile into a single executable. (I'm used to console applications) .. What files are required, and what files are simply there for debugging? What's an Application Manifest file? and a Program debug database? Why are my output files in a funky three extention format? (ex. project.vshost.exe.config) etc.. Any links to resources would be helpful. Thanks everyone.

i am working in MS Access...........when i put a command button on Access form and go to the buildEvent......code builder..........a VB file opens....... i have no idea of VB how can i change settings so that i can code in C#
|

|

You can't. Access uses VBA (Visual Basic for Applications), not C#, to write code.

what you need to do is create a project in C# and connect to access the same way you would any other ODBC compatible database. There're tons of examples if you google on it.
Otherwise [Microsoft is] toast in the long term no matter how much money they've got. They would be already if the Linux community didn't have it's head so firmly up it's own command line buffer that it looks like taking 15 years to find the desktop.

how i can validate rdf's xmlns in c#
i.e.
<rdf:rdf xmlns:rdf = "http://www.here.com/why_the_how/rdf"
xmlns:rdfs = "http://www.there.com/how_the_why/schema"
xmlns:ex = "http://www.my.fake/animals">
here what i write so far:
if (output != "" && Regex.Match(output, "<[' ']*['\n']*[' ']*[a-z0-9]+[' ']*:[' ']*rdf[' ']*['\n']*[' ']*[xmlns[' ']*:[' ']*[a-z0-9]+[' ']*['\n']*[' ']*=[' ']*['\n']*[' ']*\"http://www.[a-z0-9]+.[a-z0-9]+[[/]*[a-z0-9]*[[_]*[a-z0-9]+]*[/[a-z0-9]*]*]*\"[' ']*['\n']*[' ']*]*>").Success)
but when duplicate an xmlns it say it is not valid

|
|

I didn't study profoundly your ex. pattern, but I think you should you some method as string.Split or something for each xmlns or http that appears in your string.
