In the constructor of the Main class put some code that checks the list of processes that are running at that time. If you find you're exe there, just close the current one.

does anyone knows why ? how can i do to install my web service on IIS7 (windows server 2008) ?

void and static void problem

Dear all,

is is possible to call a static method from a non-static method and the other way around eg.:

private void Test1()
{
Test2();
}

private static void Test2()
{
//some stuff here
}

The example above will generate an error, but I would like to know if , and how it can be done.
Thank you for any assistance.

Kind regards,

Do you know how to call static methods from outside the class where it is defined? You can call it in the same way. If not then it means that you are not familiar with static methods so why do you use it? As for second question you will need an instance of a class that defines nonstatic method.

Within the same class, an instance method can call a static, but a static cannot call an instance.

The only way to do this is to have your Test2 method have an instance of the class as a parameter or make one available to it in some other way.

Forms not drawing correctly in Vista

I have an application with a form containing 2 textboxes and an animated GIF, this form works fine in all version of Windows that I have tried it on except Vista, for some reason the textboxes show the desktop through them and the GIF does not move. This is designed in VS 2003 using C# .NET 1.1.

Has anyone seen this behaviour before or have an idea what might cause it?

PRNADMINLib.PrinterCollection prnColl =
(PRNADMINLib.PrinterCollection)oMaster.get_Printers(ref oServerName);

I have the name of the server as a string which I believe needs to go into get_printers parameter but this parameter is expecting an object i.e. ref oServerName.
How can I pass my server string name to this object parameter?
Thanks

Hello DaveyM69
I am using the code in that article but the issue is where to get the oServerName as object?
I even tried the following code with slight changes to my previous code.
This is what I have now and error is FileNotFoundException on line:
PRNADMINLib.PrinterCollection prnColl =
(PRNADMINLib.PrinterCollection)oMaster.get_Printers(ref obj);

The actual error is:
The filename, directory name, or volume label syntax is incorrect. (Exception from HRESULT: 0x8007007B)

PRNADMINLib.PrintMaster oMaster = new PRNADMINLib.PrintMasterClass();
PRNADMINLib.Printer pPrinter = null;

object obj = txtServerName.Text.Trim();

PRNADMINLib.PrinterCollection prnColl =
(PRNADMINLib.PrinterCollection)oMaster.get_Printers(ref obj);
IEnumerator prnEnumerator = prnColl.GetEnumerator();
prnEnumerator.Reset();
while (prnEnumerator.MoveNext())
{
PRNADMINLib.Printer prnCurrent = prnEnumerator.Current as PRNADMINLib.Printer;
if (prnCurrent.PrinterName == strPrinter)
{
pPrinter = prnCurrent;
break;
}
}

I have corrected the code as follows but it seems the data is retrieved from the local machine as opposed to the ServerName.
Any suggestions?
PRNADMINLib.PrintMaster oMaster = new PRNADMINLib.PrintMasterClass();
PRNADMINLib.Printer pPrinter = null;

clsServer oServerName = new clsServer();

object obj = oServerName;

PRNADMINLib.PrinterCollection prnColl =
(PRNADMINLib.PrinterCollection)oMaster.get_Printers(ref obj);
IEnumerator prnEnumerator = prnColl.GetEnumerator();
prnEnumerator.Reset();
while (prnEnumerator.MoveNext())
{
PRNADMINLib.Printer prnCurrent = prnEnumerator.Current as PRNADMINLib.Printer;
if (prnCurrent.PrinterName == strPrinter)
{
pPrinter = prnCurrent;
break;
}
}

I really haven't got a clue - I just found some online resources that I thought might help you.

This page[^] has loads of info on printing of all kinds including (about halfway down) prnadmin.dll. It has a section on Enumerating Printers - but you should probably read and understand all of it before jumping to that section. It's in VB - (maybe VBS? I didn't check) but it should get you started - maybe try it at get it working in that language before translating so you'll know wheter it's a network/permission problem or just your code if it doesn't function.

I can't help you anymore than this. I have no experience of your particular problem and it seems noone else here has either as you've been asking for a long time and not got a solution, so if this doesn't help, you may be on your own. Good luck!

Does .Net 3.5 SP1 has a big integer class yet?

Does .Net 3.5 SP1 has a big integer class, with an arbitrary number of digits precision, yet?

It would be better if it is a .Net 2.0 class because all of my code is .Net 2.0 and I hope I do not have to upgrade to .Net 3.x just because of 1 class and the 2nd reason being the big .Net 3.x framework download.

Thank you in advance!

It does have one, but it is still internal.

The same (not very good) code can be found in the IronPython project.

It doesn't, but AFAIK you can use the BigInteger class from the J# library - vjslib.dll.

It has been there since 1.0. It is in the j# library. However, it got made internal for 3.5?

Remote Data Access Connection String using IP

three.leaf1-Oct-08 16:56

1-Oct-08 16:56

Hi, I'm developing a device application in C#.
I'm currently using a connection string that requires the data source and I'm using the database server name.

String RDAOleBDConnectionString = "Provider=SQLOLEDB;Data Source=" + NombreServidor + "," + Puerto + ";Integrated Security=SSPI;Initial Catalog =" + NombreBD + ";";

But I want to use the IP of the server as the Data Source, I tried to use it but it didn't work.
Also, when I'm running my application, when i try to synchronize the device and the server, I have to delete first the SQL tables because shows an error (the table already exists) when I try to get the last update in tables from the server.

Also, I haven't tested the application when I try to send the data to the server. Will i have to delete the table on the server? Or there is another way to send and receive data to the server and device without deleting tables?

The reason I don't want to delete tables is because i have a website solution manipulating this data and it can delete some of the data the device sent for different reasons, and i don't want to send data that it's already useless when the device syncs again.

thanks. Confused | :confused:
