No.The uninstall operation ,I mean,completely delete the application including db and registry entries .I could not uninstall the application yet.Is there atleast a way to debug the custom install actions?

I thought you were using an install shield with custom actions, the install shield will worry about all that for you!

Hi, I want to place my windows form 10 pixels from the right side of my user's screen.
But they have different screen resolutions, so i cant place it with a value in pixels.
So do anyone know how to do it?
I'm using this code on my form-load, to place the window:
<br />
this.Height = 175;<br />
this.Location = new Point(0, Screen.PrimaryScreen.WorkingArea.Height - this.Height);<br />
Thanks,
Elias Sorensen

<br />
int distanceFromRight=10;<br />
int distanceFromBottom=10;<br />
<br />
int screenWidth=Screen.PrimaryScreen.WorkingArea.Width;<br />
int screenHeight = Screen.PrimaryScreen.WorkingArea.Height;<br />
<br />
this.Left = screenWidth - this.Width - distanceFromRight;<br />
this.Top=screenHeight-this.Height-distanceFromBottom;<br />
<br />
or you can use
<br />
<br />
int x = screenWidth - this.Width - distanceFromRight;<br />
int y= screenHeight-this.Height-distanceFromBottom;<br />
<br />
this.SetBounds(x,y,this.Width,this.Height);<br />
<br />

Hi,
your code is placing the window at the bottom end of the screen, but flush left
since you specified zero for X.
you could replace that zero by an expression that is basically the same as you did
for Y, substituting widths for heights of course.

Hi Everyone
i've a problem using System.Security.Cryptography.RSACryptoServiceProvider class
when i work with this we must pass the RSA Crytographic parameteres to an object of the RSAParameters class
but they are in the form of Modulus, P, Q, Exponent & ...
we fill the RSAParameteres with these and pass it to the RSACryptoServiceProvider
but i have Public key and Private key from a certificate file, and i haven't Modulus, P, Q, Exponent & ...
i want to know how can i encrypt and decrypt string directly with Public & Private key not with Modulus, P, Q, Exponent & ...
thanx all.

Asymmetric keys can be created using ToXmlString() method
and can be retrieved using FromXmlString method
it can be done like this:
<br />
AsymmetricAlgorithm asym=AsymmetricAlgorithm.Create();<br />
string myCode=asym.ToXmlString(true);
<br />
RSACryptoServiceProvider rsa=new RSACryptoServiceProvider();<br />
rsa.FromXmlSring(myCode);<br />
<br />
<br />
and if you want the parameters you can use ExportParameters
and of course for converting it to xmlKey you can use ToXmlString again.
if you want get only the key (modulus) part before it you can create the complete key using a little xml operations or filling RSAParameters and importing it using ImportParameters method.
hope the post would be useful
good luck

So, what you said is completely true in the way of using generated randomly parameters, but id don't want to use them, I have Public Key & Private Key only, and I want to create parameters from them (and not randomly) and then using the parameters to encrypt and decrypt

Thanks for the answear before. I manage to cr8 app to open file as binary, and success.
but..... sometimes it can't read the whole content
This is my code :
<my code><br />
public byte[] readBin(string FILE_NAME)<br />
{<br />
FileStream fs = new FileStream(FILE_NAME, FileMode.Open, FileAccess.Read);<br />
BinaryReader r = new BinaryReader(fs);<br />
int FILE_LENGTH = (int)fs.Length;<br />
int i = 0;<br />
byte[] output = new byte[FILE_LENGTH];<br />
sbyte read;<br />
try<br />
{<br />
while (r.PeekChar() != -1)<br />
{<br />
read = r.ReadSByte();<br />
output[i++] = (byte)read;<br />
}<br />
}<br />
catch (Exception ex)<br />
{<br />
MessageBox.Show(ex.ToString());<br />
}<br />
<br />
r.Close();<br />
fs.Close();<br />
return (output);<br />
}<br />
</end of code>
It really can read few file perfectly include the file that can't be opened correctly before. but sometimes it still miss a part of file. eg:
a file contain binary like this (opened by UltraEdit32)

What are you using sbyte (signed byte) for? Keep it consistent and use byte all the way through.
Why don't you use ReadBytes[^] instead of peeking at the next item and then deciding whether to proceed or not.

oh yeah. about the sbyte, i forgot to change it back to byte. I use byte before. but I'm get frustated and try many things include change byte to sbyte.
Thank you very much. It really make my app run perfectly as i want.

Hi,
some more remarks:
1.
it is not common practice to use uppercase for variables (FILE_LENGTH)
and the underscore does not really belong there either; you have a
background in C/C++ I trust, C# coders don't do these things...
2.
there is no need for PeekChar and the End-Of-File test, since you already
know the file length
3.
there is no need for a loop; if you want to hold all the bytes in an array,
just call BinaryReader.ReadBytes(length)

hi
i want to create list of instance(s) of sql server that was installed on computer, how to do ?
thanks

Hi there .
A simple way to do this , just send and open empty connection in try catch block
Your connection string can looks like this following code :
<br />
private Boolean TestConnectionString()<br />
{<br />
string sqlServerDefaultConnectionString = "Data Source = (local) ; initial catalog = Master ; Integrated Security = true; ";<br />
<br />
SqlConnection sqlConnection = new SqlConnection();<br />
sqlConnection.ConnectionString = sqlServerDefaultConnectionString ;<br />
try<br />
{<br />
sqlConnection.Open();<br />
return true;<br />
}<br />
catch { return false; }<br />
finally <br />
{ <br />
if (!(sqlConnection == null)) <br />
{ sqlConnection.Close(); <br />
sqlConnection.Dispose();<br />
} <br />
}<br />
}<br />
<br />

That won't always work. What if there are no default instances of SQL Server installed. e.g. SQL Server 2005 Express Edition instals as an instance called SQLEXPRESS.

This sample[^] may give you the hints that you need to get you on the right tracks.

There is an article around here that shows how to get all the SQL Server instances on the visible network. Do a search in the C# database articles and you should be able to find it, since it is an app written in C#.

Is it possible to work with generic collections in crystal report?
I defined a generic list like this:
List<Employee> employeeList = new List<Employee>();
And now I want to bind this collection with crystal report and I don't know how crystal report can work with this collection fields in my employee class .
If anybody know please explain in some example .
Thank you very much .

hi i just wana know the exe of search option present in start menu of windows XP
|
|
|
|
|
Hi,
the search facility in Windows Explorer does not have its own EXE; when you
start a search no new process gets launched. You can verify this with some
system observation tool such as TaskInfo. Hence the search code is part of
what is always loaded, probably explorer.exe itself.
