Dustin,
Thank you for the prompt response, that solves my difficulty!

One thing you may want to consider is the affects of your lock on whether you have more writers than readers or the reverse for a normal environment. This[^] is an excellant article (but does not give you the code!) on various ways to perform your locks when dealing with many threads.

Thanks for the reference!
Among other snippets, I had been looking at this[^] excellent article, by Jon Skeet. Because of the way he does the code snippets, though, I got confused about locking on non-static objects (almost all his samples have static locking objects, though he does make reference to static vs. non-static in one place in the article). His Miscellanous Utility library[^] is also extremely useful (he provides a class that gives you the ability to have locks with timeouts).
Thanks again.
Sincerely,
Alexander Wiseman

I misread your question. You'll need a regular expression. If you're only looking for integers, a regex like "[0-9]+" would be good enough. You can run that against a string and look at all the matches. Have a look here: http://msdn2.microsoft.com/en-us/library/hs600312.aspx[^]

If you're using .NET 2.0 use a TryParse method, such as Int32.TryParse, to see if a string contains a number. If you're using .NET 1.x, then call Int32.Parse or Convert.ToInt32 - but be sure to wrap that call in a try/catch block because if the conversion fails, an exception will be thrown.
Checking if a string contains multiple numbers, like "12 43 656 234523 24", you can use the Split method of the String class to break the input into an array of strings. Then call Parse or TryParse on each string in the array. Beware that calling Split has subtle issues if the input value has multiple spaces in a row. You might want to remove extra spaces, or some other precautionary measure, before parsing the text into numbers.

will that work if my string is sth like "abc12def"? the check function should return true if it found a number inside a string.

No. You can use a regular expression, or loop over each character in the string and use Char.IsNumeric() to check if each char is a number.

hi
i could add exe file to my vstudio solution and set build action to Embedded Resource and by working with resources i could take it to stream .
i want to run my exe .. how to that ??
My code is ::
string fullName = this.GetResourceFullName("HDCopy.exe");//i want to run this exe
Stream stream = this.asm.GetManifestResourceStream(fullName);//load my exe to memory
//How to Run My exe from Memory (Stream) ??
private string GetResourceFullName(string resName)
{
string fullName = null;
foreach (string str in this.asm.GetManifestResourceNames())
{
if (str.EndsWith(resName))
{
fullName = str;
break;
}
}
return fullName;
}
HDCopy.exe is not dot net .

Check out the post by Steve Hanson at the bottom of this article[^]. It shows how to extract and run a managed EXE from an assembly. I'm not sure if it will work with unmanaged EXEs, though.

Beg, borrow and steal.
See CompletionCombo in the free Genghis controls:
http://www.sellsbrothers.com/tools/Genghis/[^]
If you don't like how it handles it, you can change the code. There is a lot of learning packed into the source code available there.

I think you might mean "How do I get a combobox to autocomplete input based on a letter?", if so, check out the combobox.autocomplete methods. look at AutoCompleteSource, AutoCompleteMode autocompletestringcollection.
I did this on the fly, so don't copy it word for word, but this should give you an idea.
//this assumes 2 comboboxes, cbSource and cbDestination.
<br />
private void BuildCompleteList()<br />
{<br />
AutoCompleteStringCollection cityList = new AutoCompleteStringCollection();<br />
foreach(DataRow dr in myCityInformationTable)<br />
{<br />
cityList.Add(dr["CityName"]);<br />
}<br />
cbSource.AutoCompleteCustomSource = cityList;<br />
cbList.AutoCompleteCustomSource = cityList;<br />
}<br />
In addition, remember to set the cb autocompletesource property for each combobox to custom source, and autocomplete mode to either SuggestAppend, Suggest, or Append as suits your functionality needs.
Hope this helps.
//Also, code from this was paraphrased from an example on page 160 of Brian Noyes "Data Binding with Windows Forms 2.0". I figured that I wrote this example, but I used his example as a starting point. Its a great reference for all your databinding/etc needs.

Hi,
I am trying to get the User details from an active directory but the code gives me only User names. I want their entire details like....eg. - User1 Domain/Test/Test1....
Urgent help is required.
Thanks.

The System.DirectoryServices.SearchResult class gives you all details.
After your Active Directory search, list all available properties and find the details you need:
foreach(string name in searchResult.Properties.PropertyNames)
{
Console.WriteLine("{0} = {1}", name, searchResult.Properties[name][0].ToString());
}

Hi,
Thanks. Your reply helped me a lot. One more thing I would like to ask here. I have a textbox in which let say I enter pooja.katiyar...this is my sAMAccountName. but when I click on the search button how can I get the property name for that particular value?
Actually I am trying to build a filter. In my UI I have a textbox and button. Whatever I enter in the textbox and click on the button, it should be able to find that record if it exists!
Thanks.
Pooja.

Hello All!!
I have created a windows service and the problem is when I log off my system account in which the service is currently running, the service stops. Why is this so? I want my service to run independent of my system account.
Thanx in advance

Is it a real windows service?

System.Windows.Forms.ListView does not support that.
Try the article search for "editable list view".

Yes, it can contain more than one output parameter

By asking each SqlParameter for its Value after the SqlCommand has been executed.
