Thanks for your reply.

This is what happening, i had tried your suggestion as well. but unfortunately things didnt well.

I have a COM dll in C# which i had named 'MyWrapper.dll'. Now in this dll i am referencing other 3rd party dll's which are
'NCI.EasyObjects.dll' and
'Microsoft.Practices.EnterpriseLibrary.Data.dll'. Now when i tried to strong name my MyWrapper.dll it gives the following error.

error CS1577: Assembly generation failed -- Referenced assembly 'NCI.EasyObjects' does not have a strong name
error CS1577: Assembly generation failed -- Referenced assembly 'Microsoft.Practices.EnterpriseLibrary.Data' does not have a strong name

Now like what you said i had tried

Bascilly why am i getting "is not a valid type library" error. Please help. How would i be able to strong name those dll's which are 3rd party.

Ok I found it, basically i went to the source code for each dll i was refering and then strong named it myself and compiled. Now the pain is any other dll referenced by those dlls also have to be strong named.....

But finally got the result.

thanks...

App.Config and ConfigurationSection

Anybody have any good examples of how to do this with a complex structure? This is a breeze using just straight XML, along with a few classes to represent your data in code, but using .NET 2's ConfigurationSection class and the various related attributes appears to be a royal pain in the arse for anything but simple configs. I also heard that IConfigurationSectionHandler is being obsoleted, so I probably shouldn't go down that route, either. Here's a sample of the XML format I want as an example of what I'm trying to accomplish:

<?xml version="1.0" encoding="utf-8" ?>

How can I delete all files and subfolders within a directory ?

HEllo,
I would appreciate if anyone provide me a snippet to delete all non empty subfolders and files under a directory. I tried with Directory.Delete(..), but it allows only non empty directory and I am not sure if that will delete non empty sub folders too.

Thanks and regards

Hi,
Thanks for the hint. But even using Recursion requires non empty directory, isn't it ? I want to delete all subfolders and files regardless they are empty or non empty.
Is there any easy way ?

Sure it does, but the trick is that you recursively call your method for all current subfolders and delete them afterwards when everything inside was deleted. Here some pseudocode to get you an idea of the recursive function.

void delete(string directory)
{
  delete all files in directory

  for all subdirectories in directory
  {
    call delete with current subdirectory
    delete the now empty subdirectory
  }
}

Using float.Parse(string) and language problems !

Hi !

I am using this simple : float.Parse(MyString); where MyString is "3.4" and it works fine .. on machines with language settings set to english (!!) I have tested on a machine with french settings and I get an exception (!geee!)

Unfortunately I can not change the file I parse depending on the local machine .. Is there a way I can change the language set used by the float.parsing ?

Cheers !

Use a format provider with the Parse method. To get a format provider with a period as decimal separator, you can use InvariantCulture:

float.Parse(myString, CultureInfo.InvariantCulture)

Does anyone know how or know of a website that demonstrates how to send sms messages via asp.net code without using an expensive gateway such as simplewire (they cost about 1,400/month)?

I'm not looking to bill through the cell phone (via premium SMS), I'm only looking to send out SMS text messages to users who have opted in to receive our local news & weather messages but I don't know of an affordable way to do so. At most, I would probably have no more than 10,000 SMS messages sent out per month (and even that's optimistic).

Thanks in advance.

Sensible way to scale and display large 1 bit Tiff G4!!

How can I scale up and down large(10,000*10,000) 1 bit Tiff G4 images. So far I have played with GDI+ transformations and interpolation modes but none helps quick scaling without loosing quality.It takes it more than 1 second to display such image after zoomin/zoomout.

While, Microsoft Document Imaging and IrfanView scales the same images smoothly and in less than half a second.I am willing to explore about image processing techniques, any hints/links about the same??

Thanks,

I have to make an application to write and read structures! I have to do it in c#! I know to do this in c/c++ but i have no idea how to do it in c#!

for example, my structure is like this:

(in C)
struct Info
{
int password;
string name;
etc.

}X;
( i used File *f, fopen etc..)
how to write this into a file (*.dat) and the read them...in c#

I found this example:

Hi,

add this using statement to your code:

<br />
using System.Runtime.Serialization.Formatters.Binary;<br />

use this code to read the file:

<br />
MyClass MyObject = null;<br />
BinaryFormatter binReader = new BinaryFormatter();<br />
System.IO.Stream readStream = File.Open("c:\blah.dat", FileMode.Open);<br />
MyObject = (MyClass)binReader.Deserialize(readStream);<br />
readStream.Close();<br />

and this one to write it:

<br />
MyClass MyObject = new MyClass();<br />
<br />
BinaryFormatter binWriter = new BinaryFormatter();<br />
System.IO.Stream writeStream = File.Open("c:\blah.dat", FileMode.Create);<br />
binWriter.Serialize(writeStream, MyObject);<br />
writeStream.Close();<br />

and this is the class (or struct) you want to write to a file...

<br />
[Serializable]<br />
public class MyClass<br />
{<br />
string SomeString = null;<br />
int SomeInteger = 0;<br />
string AnotherString = null;<br />
}<br />
