Also, note that you may need to involve these namespaces:
using System.IO;
using Shell32;
using System.Runtime.InteropServices;
mpr.dll should be located in your Windows directory at the following location: C:\WINDOWS\system32. It's part of the OS. (I don't think that they changed it in Vista; I use XP.)
RESOURCETYPE_DISK is a constant hex value; you can use that line as-is.
destinationUser = "Domain\Username", e.g. @"MSHOME\Jane.Doe" or "MSHOME\\Jane.Doe"
destinationPass = The password for the user above.
destinationFolder = The path to the remote folder the user account has rights to. e.g., @"\\SERVER\ShareFolder" or "\\\\SERVER\\ShareFolder"
Note that the purpose of the code snippet given was to move a file from the local machine to a remote share. You would need to modify it slightly to open files instead. (Change the last line, right before the Catch block.) You don't need to provide a drive letter to use this code; I leave mine as string.Empty.

Could it be the user that is being set to run the service has no access to that folder?
|

Yeah, it was because of the user. I figured it out though. Thanx for replying.

Hi.
I've heard somewhere that openCV doesn't develop by Intel anymore ?
Is that true?
Thanks.

Does this have anything to do with C#?

well, we can use OpenCV in C#

I'm just being lazy, I could look it up for myself, but I have no idea what openCV is.

It's an open source image recognition package. It was originally developed by Intel, but Wikipedia doesn't say who develops it now

Hi,
I am trying to get the contents of a pdf file as text in my C# .net program.
I am using PDFBox 3.0 for reading the pdf as text.
However, the problem is that the pdf file is not physically located on the
same machine and I am accessing it through a URL.
The PDFBox documentation shows that there is a static function which is of the form :
PDDocument load(URL url)
This will load a document from a url.
However, C# does not have a URL class but rather it has a URI class.
Can anybody suggest a workaround.
Or is there any other free tool that would help me achieve reading the pdf file
as text from a URL?
Any help would be appreciated.
Thanks,
Aakar.

If the method takes a URL, then it must provide a URL class, unless it just takes it as a URI or a string.
What do the docs say ? Are there samples ?

Hi,
I am dynamically exporting data from asp.net page to excel format which works fine, but when I am exporting a float value 7.0 is being exported as 7 to the excel spread sheet. It is truncating the trailing zero and the decimal point.
Thanks,
vijju

I assume there is something wrong with your code. Hard to say what, without seeing it.

Does a value such as 7.01 also get truncated to 7? If not, and 7.01 shows up as 7.01 in Excel, then this is probably just a case of the default number format in Excel being 'General' which will cause values like 7.0, or 7.00, etc., to show up as 7 in Excel.
|
|
|
|
|
Only values like 7.0 is being exported into excel as 7. if it is a default number formating, then how do you get around it, and just show the value as it is 7.0 in excel.
thanks,
vijju

That's likely only a formatting issue in Excel. What happens with non-integer values?
|
|
|
|
|
All the values are exported as string. if it is 7.01, it works fine. but if it 7.0, then excel shows it as 7.
Thanks,
vijju

hi all ,
my query as following
var result = (from page in xmlDoc.Descendants("Page")
from id in page.Descendants("User")
select new
{
Name = page.Element("Name").Value,
ID = id.Element("ID").Value,
View = id.Element("View").Value,
Add = id.Element("Add").Value,
Edit = id.Element("Edit").Value,
Delete = id.Element("Delete").Value,
Grant = id.Element("Grant").Value,
UserID = id.Element("UserID").Value,
LoginID = id.Element("LoginID").Value
}).Distinct().Where(t => t.LoginID.StartsWith(LoginID) && t.Name == Name).ToList();
return result;
above query is working well......but it is case sensitive 
i don't know where is problem........

What do you mean "it is case sensitive"? The element names? Thats because XML is case sensitive.
only two letters away from being an asset

As has been said before, XML is case-sensitive. An icky solution would be to pass it the lower-case string representation of your XML document. You could also iterate through the descendants in xmlDoc, create a new XNode based on each descendant (except with the lower-case name) add them to a new XDocument and work with that for your query.
A side note: look at what you do with your query, particularly the Where() method. You could actually merge that into the query itself, making the code look more aesthetically pleasing. AFAIK, you can do most of what you would normally do with a List, with an IEnumerable

Wow, I didn't know about that. I've never really looked into XPath queries and functions, I'll have to do that now. Thanks for the tip

Hello to all. My first thread on this forum. I'm really new with C# and I got stuck with a pointer. I've done some research with no success.
I'm making an application that works with buffers. I have to call some C++ functions with data pointers as arguments. I'm trying to not use unsafe code.
One of the functions have two parameters of type char*. I've defined on C# two buffers:
byte[] Buffer1 = new byte[SIZE];
byte[] Buffer1 = new byte[SIZE];
On the dllimport I use marshaling:
....
[MarshalAs(UnmanagedType.LPArray)] byte[] buffer1,
[MarshalAs(UnmanagedType.LPArray)] byte[] buffer2,
....
These two buffers are filled by the C++ function.
In order to retrieve the data of the buffers, I use another C++ function. This function returns in a parameter the last buffer filled:
void FillBuff(char **Pbuff);
Pbuff is a pointer to one of the byte[] buffers defined above.
The problem is that I don't know how to define a C# to assign the pointer returned by the C++ function and accessing to the buffer's content.
Any suggestion?
Thanks in advance

Hi,
when mixing managed code and unmanaged/native code, I recommend you let the managed side do the array allocations (so they are real objects); doing so, all you need is one of two things:
1. the fixed keyword, which is OK if the array is used natively only while the native function executes; here the P/Invoke prototype takes a pointer where the native code expects a pointer.
2. the GCHandle class, which allows you to:
- pin the object, so the GC can no longer move it around
- get a pointer to it
- pass that pointer to the native function
- when done, free the GCHandle object.
Here the P/Invoke prototype takes an IntPtr where the native code expects a pointer.
BTW: for strings, there are easy shortcuts:
- read-only strings can be passed as string and accepted as char*
- read/write strings can be passed as StringBuilder (call ToString when done)
