• Gareth Hunter FTP Error: Index (zero based) must be greater than or equal to zero and less than the size of the argument list.

  Hi, I am using a FTP client in my application. This FTP client is a freeware for .NET version1.1. It works fine for all files except two files. But these two files are required to FTP to a mainframe machine. I am able to FTP these two files in command prompt but getting error if I am trying to FTP through my c# application. These two files are giving two different errors mentioned below: 1. Index (zero based) must be greater than or equal to zero and less than the size of the argument list. 2. Input string was not in a correct format. But strangely, if I am trying to FTP these files to a Windows platform then it's getting FTPed successfully.

  I want use "K" instead of "000". eg change 1500 to 1.5K, Is there someone knows how to write the formate code in the " ###" float f = 1500; string formatedString = f.ToString(" ### "); If you want one decimal you can do it like this: float f = 1500; string formattedString = f.ToString("0,.0K"); The above gives at least one digit before and after the decimal point, e.g.: f = 1500 => 1.5K f = 500 => 0.5K f = 499 => 0.0K JocularJoe , That's what I want indeed.

• Skill225 CLR and thread deadlocks

  Hello, I'm hosting the CLR (.NET 2.0) in an unmanaged C++ app. The CLR is used for calling C# plugin functions through IDispatch. The C# plugins are COM visible classes and are created from the app main UI thread. They are mostly used for accessing the app through a COM primary interop assembly generated with TLBIMP.EXE. The interop between C# and the app is achieved through the default Microsoft COM wrappers. This is all working fine but I'm having a problem when the C# functions are called by the app from a worker thread. At this point the CLR attempts to interop with the app via the UI main thread which is causing a deadlock because that thread is locked while the worker thread is executing. From what I see in the call stack (b ...Show All

• Paps SelectNode - create if does not exist

  I am looking for a slick solution for this scenario: Input to a method should be an XmlDocument, an XPath expression and a string value. The inner text of the node found by the XPath expression should be set the the string value, if the node is not found it should be created first. The creation of the node is the biggest challenge here and I wonder if there is a good solution or functions which I am missing which can help me to accomplish this. Currently I put many restrictions on the XPath expression to make it work (no complicated queries: no back and forward, no search expressions). If the expression would be, e.g. /Root/Node1/Node2 I would split the expression by the slashes and navigate forward node by node and create one if it ...Show All

• syhzaidi Determine if a path is a file or a directory

  Hi all! What is the more efficient way to determine if a given path represents a file or a directory in the file system For example: C:\Test.txt -> The function must return a value indicating the path is a file. C:\Windows -> -> The function must return a value indicating the path is a directory. Thanks in advance, Marco. Thank you very much, you helped me a lot! Bye, Marco. Hi, I think that a better aproach is to use the System.IO. File .Exists and System.IO. Directory .Exists functions. Here is an example: string path = @"C:\Temp.txt" ; if (System.IO. Directory .Exists(path)) { Console .WriteLine( "The given path is a directory." ); } if (System.IO. File .Exist ...Show All

• Frank S Does the .NET framework use true I/O completion ports for socket I/O?

  Hi, I have seen conflicting information about this. Does the current .NET framework actually use real Windows completion ports for asynchronous socket I/O (I believe this would mean it would have to call the native CreateIoCompletionPort API in Kernel32.dll). Isn't this the highest performance, most scalable choice for servers _If_ .NET doesn't actually use it, what considerations made them decide not to use it Thanks, Alex Hi Amit, Well then I should be able to use Reflector to see somewhere in System.DLL a call to CreateIoCompletionPort. True But I don't. Likewise if I dump all the strings in System.DLL I also don't see "CreateIoCompletionPort" anywhere. Am I missing something Th ...Show All

• stang4lyfe NotifyParentPropertyAttribute: how does it work

  The documentation for NotifyParentPropertyAttribute says that setting it to 'true' " indicates that the parent property is notified when the value of the property that this attribute is applied to is modified. " Bravo !!! The only thing left out of such brilliantly clear documentation is the very minor explanation of HOW " the parent property is notified when the value of the property that this attribute is applied to is modified. " Perhaps someone can enlighten me on how I am supposed to know in the parent property, with this attribute set to true, of my control that a child property has been modified, and how I am supposed to know which child property has been modified.

• gurvinder_gill Why the difference between Access Query Configuration and Tableadapter Query Configuration Wizard

  I have found that I can run a query using Access query builder works fine but the same query does not work in the "TableAdapter Query Configuration Wizard". Why is this Example: SELECT * from Rental_Agreement WHERE DateSerial(year(end_date), month(end_date) , day(end_date) - 5) = Date() This works in Acess 2003 but not in the "TableAdapter Query Configuration Wizard". Yes it was an Access table. The syntax was essentially the same as yours. You could also check the sandbox mode if the error is telling you that the function is unknown. It's stored in the Registry under the following key: \\HKEY_LOCAL_MACHINE\Software\Microsoft\Jet\4.0\engines\SandboxMode The va ...Show All
