If you want to find out what files there are, look at the System.IO.Directory.GetFiles method.
If you want to work with a file, look at the methods in the System.IO.File class. You can for example use the ReadAllText method to read a text file into a string.

Unless you are in the same local network as the database server, it can not save a file on your computer. You have to download the file from the server, whihc requires something like FTP or a web server on the server, or remote desktop access to the server.

The first thing you need to do is get a byte[] (byte array) of the image. You can use BitmapData from the LockBits as suggested before, or possibly save the bitmap to a MemoryStream and get the byte array from the stream.
Getting the binary display is then trivial, just use Convert.ToString on each byte:
foreach (byte index in byteArray)
{
Console.WriteLine(Convert.ToString(index, 2).PadLeft(8, '0'));
}
DaveBTW, in software, hope and pray is not a viable strategy. (Luc Pattyn)Visual Basic is not used by normal people so we're not covering it here. (Uncyclopedia)

how to perform an action against the mouse click on the header of the c#asp.net gridview's column.
|
|
|
|
|
U can get that in Javascript
This code needs to be registered on page load.
TableObject.rows[0].onclick = Function("return YourFunctionName(this);");
Here
TableObject is ur gridview object
rows[0] gives the first row that is the header row.
Then write ur logic in "YourFunctionName"

Help me....
I am new in c# application. i want to Control memory leak and
not exceed 30mb in Task manager memory status.now in our application
the memory status is 42mb. memory size will rise if open a new GUI.
But the memory size suddenly low up to 5~10mb if minimize that GUI.
why these are happened. And how can handle this.
where i written That( Garbage collection) code. please give
all details and articles path.
Hope..
Thankyou.

Hey Anish,
If you can give more details like what controls are you using or any specific code that you suspect to be the culprit , because its hard to find out any thing on the information you have mentioned , the information is too generic , to think of a solution

run concurrently.
But we used lot of GUI Component.

Task manager does give an accurate picture of how much memory your app is using. Use Perfmon as described in the article.

You forgot the "not" in "Task manager does not give an accurate picture of how much memory your app is using.".

As mentioned in the thread, the task manager does not give you an accurate measure of the amount of memory used.
As you are new to C# you are probably new to how the .NET memory management works. It allocates more memory if needed, but does not return it just because it's unused at the moment, but rather when the system needs it.
A system doesn't run better from having a lot of unused memory. On the contrary, trying to minimise the memory usage when there is no need for the memory is just unnecessary work for the system.
anishkannan wrote: now in our application the memory status is 42mb. memory size will rise if open a new GUI.

That is perfectly normal. When you minimise the application, the system sends a signal to it to try to free up some unused memory.
anishkannan wrote: And how can handle this.
It doesn't need handling. The memory management in .NET takes care of it all.
anishkannan wrote: where i written That( Garbage collection) code.
Don't mess with the garbage collector unless you really have an actual memory management problem. That is quite rare, and your situation is definitely not it.

Hi all,
I am trying to create a XML using DataSet.WriteXml.
The XML was created, but its not creating any node for NULLs.
I also tried by query
"SELECT (SELECT * FROM TBL_NAME FOR XML AUTO, ELEMENTS XSINIL) "
but the out put structure was changed. For bulk copy to SQL its not supporting due the columnnames were not matching.
Please suggest me how to create a XML including NULLs.
Thanks in advance.

|

Dunno, I've never used DataSet.WriteXml; for that matter, I rarely use a DataSet.
I suggest using an XmlDocument or XmlTextWriter to create XML files.
What I generally do for nulls is have an IsNull attribute that I can set:
<SomeValue IsNull="false" >blah</SomeValue>
<SomeValue IsNull="false" />
<SomeValue IsNull="true" />

Hello all,
i have the requirement to Extract data from image. can u plz help me out with the code.
I am strugling to extract data from image file using C# (.net 2.0)
For Ex: I have an image with a number.. I need process the image and extract the number and store it in sql DB.
Please help me for this implementation using C#.
Thanks

What kind of extraction are you talking about?
If it's simply a number presented as an image, google for OCR libraries. If the data is hidden in your images, google for steganography. Also, Corinna John has an excellent set of articles on the latter, here at CodeProject.
Cheers,
Vıkram.
