I think you will find the same code will work, almost in C#. Your code is using char arrays, not byte arrays (In c I think there is no difference) however, in C# you have the option of:
string abc;
abc.ToCharArray();
or if you insist on bytes:
string abc;
System.Text.ASCIIEncoding ae = new System.Text.ASCIIEncoding();
ae.GetBytes(abc);

Thank you.
So do you mean I leave the rest of the code as it is?
And also, Would you possibly be able to point me in the right direction with a function to ENCODE the byte or char array I get from the above, back inot the original string please?
Thank you
Steve

Dear Qwertz
Thank you, but, the follwoing....
const string INST_ID = "23334 324234 324234 234234";
byte[] instIdInByteArray = Encoding.ASCII.GetBytes(INST_ID);
string instIdInString = Encoding.ASCII.GetString(instIdInByteArray);
That simply returns each byte for each char in the string, so I end up with a larger string.
I want the actual encoding of the digits in the string, into a byte array that is a decimal encoding in litle endian byte order of the digits.
Thank you
Steve

I know this is off topic, but am I missing something here?
This piece of code caught my eye:
if (strlen(InstID) != 58)
fprintf(stderr, "Warning: Installation ID has non-standard length.\n");
if (strlen(InstID) % 7 < 2)
{
fprintf(stderr, "Installation ID has invalid length.\n");
return -1;
}
My C++ is a bit rusty but why do that? Surely, the second if statement will always be true if the first one is false.
|
|
|
|
|
How so?
strlen(InstID) =
7m + {0, 1}: First is true (not 58), second is true (0 or 1).
58: First is false (not 58), second is false (2).
7m + {2, 3, 4, 5, 6}: First is true (anything but 58), second is false (2, 3, 4, 5, 6).
So basically, the length can only be of the form 58, but maybe 7m + {2, 3, 4, 5, 6} are acceptable.
Still have no idea how this makes sense though.

Yes, you are right. I was having a brain-fart.

I'm trying to learn how to communicate between applications and evaluation of the various projects i've come across have helped, but i still have one area i'm not having luck with. Lets say i have a tcpclient connected and it sends a message to server, servers listener accepts it adds the client object to a list and can respond to requests from the client. The connection stays active and my client gui app can press button repeating the process.
Now on sever side gui app lets say i want to initiate a message to the client. I try to utilize the same client object and send some data, but client does not get the message until the connection ends, ie a disconnect.
Anyone have any code examples or links to some that would demonstrate this process?

Good morning folks!
I'm trying to get a Session and redirect the user to another page, but it doesn' work.
If the user doesn't have permission then redirect to root: Default.aspx.
<br />
private UserStats userStats;<br />
<br />
protected void Session_Start(object sender, EventArgs e)<br />
{<br />
if ((UserStats)Session["UserStats"] != null)<br />
{<br />
userStats = (UserStats)Session["UserStats"];<br />
}<br />
}<br />
<br />
protected string PageBasePath<br />
{<br />
get<br />
{<br />
string basePathString = string.Format("{0}://{1}{2}", Request.Url.Scheme, Request.Url.Authority, Request.ApplicationPath);<br />
if (!basePathString.EndsWith("/")) basePathString = basePathString + "/";<br />
return basePathString;<br />
}<br />
}<br />
<br />
protected bool Compare(String x, String y)<br />
{<br />
Regex rg = new Regex(y);<br />
return rg.IsMatch(x);<br />
}<br />
<br />
protected void Application_PreRequestHandlerExecute(object sender, EventArgs e)<br />
{<br />
<br />
String ExtendsPermissions = "aspx|jpg|png"; <br />
String page = HttpContext.Current.Request.Path.ToString(); <br />
try<br />
{<br />
String expression = @"(/MYSITE/DIRECTORY/)(([a-zA-Z0-9_\/]+)*)\.(" + ExtendsPermissions + ")$";<br />
if (Compare(page, expression ) && userStats.Permission.Equals("DIRECTORY") )<br />
{ <br />
}<br />
else<br />
{<br />
<br />
HttpContext.Current.Response.Redirect(PageBasePath);
<br />
}<br />
}<br />
catch (Exception ex)<br />
{<br />
Response.Write(ex.Message);<br />
}<br />

hi all,
I wrote a service in c# and I prepared a setup to service but now
I want to unistall if service install before and then install last setup
how I do this??
thanks..
|

So you want to do an upgrade??
I will assume you have used a VS Setup project for doing this.
If you want your service to be updated and you use VS2008. Do the following:
Add a custom action for Install, Commit, Rollback and Uninstall and add "Primary output..." of your service project.
Add the Condition NOT PREVIOUSVERSIONSINSTALLED for Install and Commit.
In your Setup-project choose RemovePreviousVersion: True and change the UpgradeCode and Version .
IF you are using VS2005 you don't have to add the NOT PREVIOUSVERSIONSINSTALLED as a Condition. This was altered in VS2008.
I also assumed that you added a ProjectInstaller to your service project

"Add the Condition NOT PREVIOUSVERSIONSINSTALLED for Install and Commit.

how I add NOT PREVIOUSVERSIONSINSTALLED condition
and choose RemovePreviousVersion where is it??
|
|
|
|
|
I found them and I did them but it is not work
I unistall service "sc delete servisname" from command prompt ,is it necessary tu use this command?
|
|

|

No not really. Just to make sure I understand your question correctly, is this your scenario:
You have created a Windows Service (NT Service) and you have added a ProjectInstaller in that project.
You added a Setup project to your solution to install your Windows Service.
Now you want to make an upgrade of your Service, for instance upgrading from version 1.0 to 2.0.
Then you should do the following:
1. Create a Custom action to your Setup project for Install, Commit, Rollback and Uninstall, adding the Project Output.. of your Windows Service.
2. Change RemovePreviousVersion from false to true .
3. Change the Version of your Setup project (i.e. from 1.0 to 2.0).
4. Change the UpgradeCode of your Setup project (I believe VS asks you if you want to change this when you change the Version ).
5. If you are using VS 2008 (or 2010?), add the NOT PREVIOUSVERSIONSINSTALLED as a Condition . If you are using VS 2005, this is not necessary (Microsoft changed this behaviour between the 2005 and 2008 version of VS. This means that in 2008 the Service will not really be uninstalled in the Service Control Manager - only the binaries will we changed).
I know i repeated myself a bit from my previous answer, but this is actually the only steps you need to go through to make it work. If it doesn't work - please provide the code in your ProjectInstaller class , because maybe something is missing there. Also provide any error messages displayed.
You should not have to make any commands like "sc delete servisname" etc. All this should be taken care of by MSI.

thanks for your answers,you understand correctly my problem
my projectinstaller class only like this:
namespace SistemServis
{
[RunInstaller(true)]
public partial class ProjectInstaller : Installer
{
public ProjectInstaller()
{
InitializeComponent();
}
}
I added aproject installer but I didn't add anything else.
Do I have to write different things???
|
|
|
|
|
Okay, then that's your problem. You have to add code to the ProjectInstaller class that actually does the installation of your service. In your case it would look something like this (from MSDN example):
namespace SistemServis
{
[RunInstaller(true)]
public partial class ProjectInstaller : Installer
{
private ServiceInstaller serviceInstaller;
private ServiceProcessInstaller processInstaller;
public ProjectInstaller()
{
InitializeComponent();
processInstaller = new ServiceProcessInstaller();
serviceInstaller = new ServiceInstaller();
processInstaller.Account = ServiceAccount.LocalSystem;
serviceInstaller.StartType = ServiceStartMode.Manual;
serviceInstaller.ServiceName = "YourServiceName";
Installers.Add(serviceInstaller);
Installers.Add(processInstaller);
}
}
}
Good luck!

nothing changed
when I tried to install, service all times give this error:
error 1001:the apperred system is still there.
|
|
|
|
|
hmm.. that's odd. Could you make sure that your service is uninstalled when you run your "new" MSI (the one generated with the code I added), then make an install, change the version number (and upgrade code) and then perform an upgrade?

Hi Everyone
I am writing an Excel document in C#. I am writing it in 'Visual Studio 2008' and the project type is a '2007 Excel Workbook'. I was able to add all the controls and functionality I want to the Excel Workbook and it works. The problem is when I try to 'compile' (not sure if compile is the right word) the Excel document, it's dependent on a bunch of other files.
for example the resulting ExcelWorkbook2.xlsx file is dependent on a bunch of other files like:
ExcelWorkbook2.vsto
ExcelWorkbook2.dll
ExcelWorkbook2.dll.manifest
Is there a way to embed these files into the xlsx file so that the ExcelWorkbook2.xlsx will work on it's own?
I am writing this for some corporate people in my company and I think they'll have a hard time to remember to copy all these dependent files along with the Excel Workbook. So it would be nice to have everything in one file. I could probably write VBA Macros instead, but it would be nice to do it in C#.
Any help is appreciated
Regards
KOM UIT DAAAAA!!!

Ncb files are used for intellisense in C++ projects - at least that's the information I found in the web. Now I have a solution containing some 20 C# projects and one (1) C++ project, the main project being a C# project.
Before opening the solution (in Visual Studio 2005 Professional), I deleted the ncb file found in that project's directory. After closing the solution, an ncb file (with more than the size of all dlls and pdbs summed up) resides there.
Since the project is a C# project, I think that file is pretty useless, isn't it? How can I safely get rid of it?
By the way, I tried the tricks to be found by Google for C++ projects, they did not help here.

Did you try this:
Rename the file (VS root path)\VC\vcpackages\feacp.dll, then delete the .ncb file and now it should not be created again.

Thanks for the hint. I tried it, then the freshly created ncb file was only a few kB in size. But intellisense in C++ projects did not work anymore...
