I've a server application, which will return some strings for different users. The users can set their locale to the server, so the return string is will be in the language they specified.
In my scenario, i coudln't use CultureInfo.CurrentCulture as my server has to serve differnt locales. Is it the only resort I've to use is creating different resources file, and load it up with differnt ResourceManagers, and get the string myself. Can I built them into 1 assembly and loading with 1 ResourceManager only ? As I heard that ResourceManager is quite resource consuming.
Hiya, Everybody ^^

Hi,
I want to implement several custom cursors in my application. Is it possible to load the cursors from an imagelist or do I have to put them as a ressource in my application and load them this way?
Thanks,

Hi,
I have written a SQL database application which works great. The client has a remote pc (off site - which has its own database) and a remote laptop (on-site - which has its own database) so the employee can work if the power goes out. What I want to set up is a way to extract changes made to the database into packets and FTP to the offsite pc and read in those changes. I want to achieve a simular result but over the network, not through FTP.
Is there a way to extract changes from an SQL database of all transactions so i can send this information to the offsite and onsite pc?
OR
Is there any way to achieve this????
I am open to realistic suggestions or products.
Thanks
Stephen

Replication will help you out. But i am not sure about how to configure Replication in SQL Server.

Unfortunately, there is no .NET way of launching the .NET app. Your still dealing with a COM based app that knows nothing of the .NET Framework. So, the .NET application and Framework must be adapted to work in the COM world. That's why you need all the configuration on the client side. You can't get around it...

hi
how can i make the tap key when pressed go to specific columns
thx
|
|
|
|
|
Override ProcessCmdKey and change the CurrentCell property when ever Tab Key is being pressed. Refer the below code for details.
public class myGrid: System.Windows.Forms.DataGrid
{
protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
if(keyData == Keys.Tab)
{
this.CurrentCell = new DataGridCell
(this.CurrentCell.RowNumber,1);
}
return base.ProcessCmdKey (ref msg, keyData);
}
}
Do revert back whether it could solve your purpose or not?

hi
i make the Right to left Property of DataGrid to "true"
but thier is a problem that the cells when i write Numbers in it ... it displays this numbers in "arabic"
i want the numbers to be in "English"
what can i do !!?
Help !?

First tell me what the Localizble property value of your parent control. I mean if your datagrid contained in a form. Then what is the Localizble property value of that form. If it is True. Set it back to False.Why cause the RightToLeft property is an ambient property. An ambient property is a property on a control that, if not set, is retrieved from the parent control.

Hello all 
I have this problem with managing resources. I am writing a cataloging application in which i need to compute a MD5 hash value for each file in the tree structure given a directory. This is done recursively. Now until I have added a function to compute the hash everything was working smoothely however now the application freezes.
This could be because i do not have enough free resources. I tried calling a Dispose method of the MD5CryptoServiceProvier but it is protected therefore not allowed to be accessed.
IS Garbage Collector an option? If so where should it be applied.
To give you an idea. The function ComputeHash looks the following:
private string ComputeDigest(FileInfo file)<br />
{ <br />
MD5CryptoServiceProvider csp = new MD5CryptoServiceProvider();<br />
FileStream fstream;<br />
try<br />
{<br />
fstream = File.OpenRead(file.FullName);<br />
}<br />
catch(Exception e)<br />
{<br />
MessageBox.Show("Error Occured: " + e.Message);<br />
return null;<br />
}<br />
byte [] hash = csp.ComputeHash(fstream);<br />
fstream.Close();<br />
string hash_string = String.Copy(BitConverter.ToString(hash));<br />
csp.Clear();<br />
return hash_string;<br />
}

Im building a C# wrapper for an unmanaged dll (BladeEnc.dll) and im not an expert in this, anyways.
I need to pass the following struct in:
BE_ERR beInitStream( PBE_CONFIG pbeConfig, PDWORD dwSamples, PDWORD dwBufferSize, PHBE_STREAM phbeStream )
typedef struct {
DWORD dwConfig;
union {
struct {
DWORD dwSampleRate;
BYTE byMode;
WORD wBitrate;
BOOL bPrivate;
BOOL bCRC;
BOOL bCopyright;
BOOL bOriginal;
} mp3;
struct {
DWORD dwSampleRate;
BYTE byMode;
WORD wBitrate;
BYTE byEncodingMethod;
} aac;
} format;
} BE_CONFIG, *PBE_CONFIG;
Now i got this in C#:
[StructLayout(LayoutKind.Sequential, Pack = 1)]
internal struct BE_CONFIG
{
public Int32 dwConfig;
public sFormat format;
}
[StructLayout(LayoutKind.Sequential)]
public struct sFormat
{
public sMP3 mp3;
public sAAC aac;
}
[StructLayout(LayoutKind.Sequential)]
public struct sMP3
{
public Int32 dwSampleRate;
public byte byMode;
public Int16 wBitrate;
public bool bPrivate;
public bool bCRC;
public bool bCopyright;
public bool bOriginal;
}
[StructLayout(LayoutKind.Sequential)]
public struct sAAC
{
public Int32 dwSampleRate;
public byte byMode;
public Int16 wBitrate;
public byte byEncodingMethod;
}
Now im testing this function (beInitStream) with the following code:
BE_CONFIG config;
Int32 dwSamples = 0;
Int32 dwBufferSize = 0;
int output;
IntPtr pConfig = IntPtr.Zero;
FileStream fs = new FileStream("C:\\test.mp3", FileMode.Create, FileAccess.Write);
config.dwConfig = BE_CONFIG_MP3;
config.format.mp3.dwSampleRate = 44100;
config.format.mp3.byMode = BE_MP3_MODE_STEREO;
config.format.mp3.bPrivate = false;
config.format.mp3.bCRC = false;
config.format.mp3.bCopyright = false;
config.format.mp3.bOriginal = false;
Marshal.StructureToPtr(Marshal.SizeOf(config), Marshal.AllocHGlobal(pConfig), false);
output = beInitStream(ref pConfig, ref dwSamples, ref dwBufferSize, fs.Handle);
Marshal.FreeHGlobal(pConfig);
fs.Close();
I keep getting the error BE_ERR_INVALID_FORMAT_PARAMETERS, so im assuming that there is something wrong with the structure.
Could anyone confirm and/or help me with this?

How do I send a string to the printer when I click on a specific button? And how do I add a CR (carriage return) into a string?

Printing is a complex topic (simplified by Windows Forms and .NET, but still complex). Even to print a single string, you need to create a PrintDocument object, and install handlers for various events. See MSDN documentation.
Michael Williams wrote:

That's easier. Just concatenate a "\n". That should work, but in some cases, you'll need the full CRLF: "\n\r".
strLines = strLine1 + "\n" + strLine2; -- LuisR

I need to read up on the implication of server farm AND database clustering on COM+ transaction. Any reference? Preferably URL's so I don't need to rush off to the bookstore.
Thanks in advance.

I'n new to programming and I'm writing a simple app where I generate a 2 digit random number in one textbox. When I click a button, I want the value of that textbox to appear inside another textbox.
After playing with this for hours (and learning along the way), I'm getting nowhere.... The closest I've come is this;
textBox1a.Text = (textBox1.ToString());
The text is entered into the text box as follows:
System.Windows.Forms.TextBox, Text: xx (where xx is the random #)
I don't want this - I just want the random number in place and not the whole string.
Any suggestions?
Thanks,
Mike

I recommand you to study or refer few C# programming books. MSDN is a nice guide for newbee like you. Better don't get into Visual Studio.NET IDE untile and unless you know little about how to use .NET laguages.
Here is the solution for your issue.
textBox1a.Text = (textBox1.Text.ToString());

MSDN has a lot of useful information for anyone programming with Microsoft technologies. (I'll assume the condescending tone was unintentional.)

I think that is bad advice. Read all you can, yes, but do it in addition to coding, not instead of it.

Why, again, are you using .ToString() on a string???

There are no default properties in C#, so you'll need to specifically state what property of textBox1 you're trying to get at, which, in this case, is the Text property.
textBox1a.Text = textBox1.Text; The compiler can't infer what you meant because you could have just as easily wanted to display textBox1's Name, BackColor, or PasswordChar, etc., in textBox1a.

Thanks for the help. The first reply solved my problem. I agree that I should be reading AND doing to learn the mosr efficient way. Thanks Charlie!
I have another ? that I'll post in a new thread.
