Hi,
I don't know for sure, I suspect a service without a GUI may fail to display any problem it may have, all catch blocks that use MessageBox may become useless. Make sure there are no exceptions going unnoticed, so log them to a file or to EventLog, and make sure this works. Then go after the SerialPort problem.

one program with "advanced regedit" (regedit33)name, can change value's type.
exe : http://garr.dl.sourceforge.net/sourceforge/regedt33/regedt33.exe
source and exe : http://garr.dl.sourceforge.net/sourceforge/regedt33/regedt33.rar
registrykey.getvalue() method does not supprt REG_NONE values
and I have an REG_NONE value and I can change this value type to REG_DWORD
in this program .
I'm looking for a way to read REG_NONE types or read them as REG_DWORD
or change type of REG_NONE to REG_DWORD and read value in C#.

That someone was Luc[^]. Have you made any progress since your last answer?
Look here[^] for the information on the API itself. Search Google for P/Invoke example's to import the function.
In theory, an empty key would simply result in a null-value. Is there any special requirement to distinguish between empty keys and a key with no datatype?

Hello,
I'm having an Outlook 2007 addin, which opens an existing word 2007 document and fills in some userdata, which I receive from Outlook.
The next step is an actionpane, which should be opened in this worddocument.
I wrote some worddocumenttemplate in VS 2008 and got everything working:
...
namespace WordDocumentTaskpane
{
public partial class ThisDocument
{
private HelloControl hello = new HelloControl();
private void ThisDocument_Startup(object sender, System.EventArgs e)
{
this.ActionsPane.Controls.Add(hello);
}
...
This HelloControl is just a userconstrol to display some items from a database.
By working hard on the Outlook addin, I can't get the taskpane / actionspane created in the opend worddocument, because I can't call the according methods.
Are there any basic ideas?

Hello,
I've finished my application in C#,

Thanks (:

Is it a web or windows app? I'm assuming it is Windows so if you want it to be available for all users on the intranet you could use a click once installation, the app won't run from the server but it'll be available there for users to install.

You're rigth,
this is a windows application.
I'am trying to find a way that the users won't be needed to install the app on their computer because they'll have to install also the ODBC.
Isn't there any option that the users will be able to use it throught the server?

|

|
|
No,
i don't want all the users to connect by remote to my server.
|
|
|
|
|
Then why ask

Remote desktop is the way to go, why not? You can set up limited user accounts or safeguards to protect your server.

i am using ms sql server 2005. i used full text search (fts) facility. now i want to know that does fts cares about sequence of a phrase. for example
("select * from news AS N INNER JOIN containstable(news,datacontent,'local' AND 'company') AS A ON N.[id]=A.[KEY] ORDER BY A.RANK DESC",connec)
this returns results that includes local and company but anywhere in the document. but i want it like "my local company is very big." so i mean the word "company" must come after "local" (at least 1 time) to have a result. how can i do this. i tried it as 'local company' but an error occured.

Hi,
a little search for sql "full text search" phrase should lead you to the answer. It seems to be the phrases need to be in double quotes (as with most search engines), and of course the entire literal string should be in single quotes as usual.

Hi,
My requirement is to read the file one by one and update the content in database.
I'm getting Out of memory Exception while reading 32Mb text file. I ve used streamReader to read the File.
StreamReader strReader = new StreamReader(filePath);
return strReader.ReadToEnd();
I have tried with ReadLine() also. Same error comes.
Is there any solutions for this?
Thanks in advance

String _result = String.Empty;
using(StreamReader strReader = new StreamReader(filePath))
{
_result = strReader.ReadToEnd();
}
return _result;

Hi,
how many files (and how many megabytes of accumulated file data) does it take to get the OOM Exception? I suspect you are getting large-heap fragmentation.

Luc is probably right about heap fragmentation being the problem.
Instead of creating new strings with each read and flogging the heap to death like this:
string fileText ="";
while (strReader.EndOfFile())
{
fileText += strReader.ReadLine();
}
return fileText;
Use a stringBuilder initialized to the size of the file so that you only have a single memory allocation.
stringBuilder fileText = new stringBuilder(sizeOfFile);
while (strReader.EndOfFile())
{
fileText.AppendLine(strReader.ReadLine());
}
return fileText;

Textbox is having 3 lines
how to get lines count?
can anyone help me?

//to find number of lines
int lines = textBox1.Lines.Length;
//to find number of words
int words = textBox1.Text.Length;
//Note: If you find any of the answer is correct then vote for it. So that other members will know that the reply is correct....

Thank you very much.
this code is working fine.

Is incorrect - it gives the number of characters not words. I do not know of a built in function to give the word count of a text box, but you can do it with a regex:
Regex.Matches(textBox1.Text, @"[\S]+").Count
