Using above code, I got succeeded in printing PDF file through command line. But it runs the Acrobat Reader and opens Save dialog box.
In my case, I want to suppress Save dialog box and save the file on other location using c# coding. I mean I want to save a PDF file behind the scene.

If I open a command line on that server and type that command, it returns all of the scheduled tasks for the system. If I run that code, it returns a blank page.
I have a very simple and stupid problem but I'm unable to find a solution. I'm trying to create folders and files locally through my code, however I get a permission exception when I try to write in a folder in my application. Normally I'd run this on a remote server, and ask the system administrator for writing permission on this specific folder, but I need to run this locally for the moment.
If I navigate to the file in windows explorer, and right click the folder and click on Properties, I can see that it's set as Read Only. However when I try to disable this tickbox and click on Accept, nothing happens. It ignores me, and next time I open the Properties of this same folder, it's still marked as Read Only.
I've googled this and found a solution which implies using MS-DOS and a command named "attrib". This is not working for me either. I also read about adding an ASP.NET account on my PC and granting the right permissions to this, but I'm not sure how to do is.
I have a couple of powershell command that are very simple.
disable-mailbox dadelgad -confirm:$false
enable-mailbox -identity 'dadelgad' -database 'NET5014DB10' -Alias 'dadelgad'
The first command is to disable an exchange mailbox and the second enables the mailbox. I am logged in as a user who is in the Organization Management group which has full admin priviledges to Exchange but is not a domain admin. If I run these commands directly in Powershell, they work fine but they do not work when called from C#.
I created a very simple windows forms app that has a couple of buttons that invokes these commands from C# code. Running the app as the user with full Exchange right, most commands work with no problem such as get-mailbox -identity 'dadelgad'. I can set flags in Exchange, add alias emails and do most functions but I cannot disable or enable an account.Do I need to be a domain admin to do these functions. It almost seems like a permission issue but the user has full rights to Exchange and can perform both of these commands directly in Powershell.
I've run into a problem after installing the 64 bit Oracle client onto my Win 7 x64 dev box. I have installed and configured the oracle client and added a reference to it in my library project and it runs without problems when deployed to a Win 2008 R2 server; however I cannot run it in the built-in VS2010 debugger.
The code throws a BadImageFormatException when the .open() statement is called on the connection object.
I figured out that if I will run it in IIS and move the application out of the default application pool, the error goes away for some reason.
However, I can't do this when I'm running the test project (MSTest) and I the result is that I cannot run unit tests against this code. Yes, I can mock it, but I would really like to understand and eliminate this error. There are several cases where I would like to test against some test data in the database.

View 1 RepliesI have an application that I use to run Exchange Powershell commands inside C# code like below. This is an example of the relevant lines I use to run the powershell command.
RunspaceConfiguration rsConfig = RunspaceConfiguration.Create();
PSSnapInException snapInException = null;
//load Exchange shell
rsConfig.AddPSSnapIn("Microsoft.Exchange.Management.PowerShell.E2010", out snapInException);
Runspace runSpace = RunspaceFactory.CreateRunspace(rsConfig);
//open runspace
runSpace.Open();
//setup pipeline
Pipeline pipeLine = runSpace.CreatePipeline();
String sScript = "get-mailbox -identity 'rj'";
//add script to pipeline
pipeLine.Commands.AddScript(sScript);
//run the script
pipeLine.Invoke();
pipeLine.Dispose();
This code works perfect in all cases until now. the script I am trying to run instead of the one above is to set the RetentionPolicy for a mailbox. The script I am trying to run looks like this: Set-Mailbox -Identity 'rj' -RetentionPolicy 'Main Campus Retention Policy' When I run this in powershell itself it works perfectly but when I try to run it using the code below I get the error, "Cannot invoke this function because the current host does not implement it."
From this error, it almost seems like the command that runs in C# cannot run the RetentionPolicy command but that doesn't make much sense. I have Googled this and tried everything suggested but no luck.
I have a web service that runs a query (from C#) to get a dataset from sql server. I get the following time out error. Googling on this error says, you can set the timeout on command object. But I am not using command object to set the timeout. This is the code I am using to get the dataset.

I want to issue an INSERT command for an SQL Server table using DataAdapter without first issuing a SELECT command. Could anybody send me lines of code to handle this? Also how do i manage INSERT into selective table columns (I have 10 columns but i only want to update 2 of them)?
View 2 RepliesI am working with odbcCommand class, in one case I got error that QueryTimeout Expired. Even though this SP is taking only 3-4 secs in DB to execute these specific values, When I set the CommandTimeout=0, then it worked fine.
1)Is it necessary to always use this property while working with Command Class.
2)If it is not suggested to use, but still if I use it then how it will impact the performance.
Below is my code sample.
OdbcConnection conObj;
OdbcCommand cmdObj;
OdbcDataAdapter daObj = new OdbcDataAdapter();
public DataTable GetIFAContractNoteData(string RecipientIDIFACN, DateTime BatchDateIFACN, int TransmittalReportIDIFACN) {
conObj = new OdbcConnection(GlobalVariables.strDsnName + ";" + GlobalVariables.strDsnDataBase + ";" + GlobalVariables.strDsnUserID + ";" + GlobalVariables.strDsnPassword);

I've recently started working in ASP.NET and RDBMS.I'm making a test form where I can do basic add,update,delete operations.I'm using OracleDataClient to do the DB operations.I was able to populate a listbox using OracleDataAdapter.
Now after clicking on update button,I intend to Update in DB.I've Dataadapter with it's update property.But the update query is not happening.The examples I saw over net all have Select command before Update.Is it actually like that or am I missing some point.
How does Oracle DataClient work with Insert,Update,Delete Commands.
I am executing a long-running Oracle stored procedure from .NET. The procedure takes about three hours to run. Ideally, the user should be able to kick off the procedure, close the browser, and come back later to check the results.
The problem is that the connection to the Oracle procedure is lost after exactly an hour. As you would expect, the Oracle procedre runs to completion if it is executed from SQL Plus. Strangely enough, it will also run to completion if I run in debug mode on my local machine (I start two threads, one of which executes the procedure. I set a breakpoint on the second thread).
Here is my connection string:
data source= (DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=serverx)(PORT=1521)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=TestSID)))
Some relevant sections from web.config:
<sessionState mode="InProc" cookieless="false" timeout="3000" stateNetworkTimeout="72000"/>
<httpRuntime executionTimeout="18000" maxRequestLength="2097151" />
Any thoughts as to why the connection is being lost in exactly an hour, and what I can do to maintain the connection until the procedure finishes?
i'm trying to issue a select command in my app soi could execute the command and retrive the data into a string variable.the problem is that this command is overloaded with DataSourceSelectArgument and i can't figure out what it is.i'm using sql server express and when issue a n insert command for example sq.Insert(); i have no problems.this the command that's holding me:
SqlDataSource sq = new SqlDataSource();
sq.ConnectionString = ConfigurationManager.ConnectionStrings["CustomerDatabaseConnectionString1"].ToString();
sq.SelectCommandType = SqlDataSourceCommandType.Text;
sq.SelectCommand = "SELECT * FROM CustomerTable where customerID = 1";
string result = sq.Select(some overload that's stopping me);

I am working on a 3-tier asp.net application. Currently I'm stuck up in a situation where I need to handle a specific type of exception (User Defined) in DAL and Show alert to the user if that exception occurs in DAL.
I tried following things:
1) I raised that exception from the DAL and catch it in BLL and throw a new BLL exception to for that DAL exception and finally catch it in the UI layer to show the alert to the user. I've successfully implement this in my project. But there are some issues in this approach. First of all I feel this is not right way to do this as it may lead to performance related issues. Secondly, the application contains more than 500 pages and classes. so I need to attach additional catch block in every method to catch the BLL exception. which is the last option i'd like to take.
2) in second approach I logged the the DAL exception into a text file. but problem in this approach is that how could the UI layer know that exception has occurred and show the alert to the user. Is there any event in asp.net where i could handle all this activities?
my question is what is the best approach to handle this type of situation? Will Exception handling block help me in this?
I've tried reading many articles on this but i couldn't get an answer for my question? I might not be using right keywords for my search.
In ASP.NET,How can i know the Specific details about an exception (like What kind of Exception it is (FileNotFound /Arithmentc etc..) )from a General Exception class object.
View 2 Replieshow would i do my Gridview delete command like a update command?
im using a datasource... and my delete command is like my update command... so i can change the status into "INACTIVE"...
DeleteCommand="UPDATE ACCOUNT_MAINTENANCE SET am_status = 'INACTIVE' WHERE (accmain_no = @accmain_no)"
UpdateCommand="UPDATE [ACCOUNT_MAINTENANCE] SET [account_type] = UPPER(@account_type), [min_deposit] = @min_deposit, [min_capital] = @min_capital WHERE [accmain_no] = @accmain_no"
when i press my delete command at gridview... the status changed into "INACTIVE" but when i refresh or press f5... it automatically update the status into "INACTIVE" also...
i have this application structure:
1. Presentation Layer which calls
2. Business Logic Layer which in turn calls
3. Data Access Layer to do the dealing with the database.
Now i have a Contacts page from where i can add a new contact to the database.So to add a New Contact i fill in all the required details and then call a Add Method (residing in the BLL) from the page, which in turn call a Add Method residing in the DAL.this method in the DAL returns the Current Identity of the record which is then return back to the BLL method and finally delivered on the page.this is fine. but what if a get an exception how do i handle it properly because the method in DAL has a return type of int and i dont want to throw another error!! coz other wise i will have to write try catch in almost all the methods.
//something like this
public int AddMethod(ContactClass contactObj)
{
int result = 0;[code]...
rather i want to show the user a user-friendly message which they can easily understand and in the mean while i will send a mail to myself documenting the Error that just occurred.how can i implement my custom exception classes.
Is there any way to uniquely identify a particular exception from the general exception class.
i.e any property or method that retrieves a unique identifier that to identify a particular exception.
I have kept some error values and corresponding error texts in an xml file. I want to read that xml file and have to taken the error ids and fix the corresponding texts to a label. in the case of a system exception we have to identify a particular exception.
Difference between Exception and Fault Exception..?
Can i use Fault Exception when i get the Exception.
We're getting this InternalSubStringWithChecks exception with our application's healthMonitoring.

I have simple 3 tier web application and have mostly CRUDE functionalities. Recently I required to add new console application to the existing solution in which I call data layer methods for retrieving data from DB but I get an exception "The type initializer for threw an exception."When I debugged I found that the exception is thrown at datalayer on first line of class where I get connectionstring from
web.config, the code is public static readonly string CONNECT_STRING =
ConfigurationManager.ConnectionStrings["DbConnectString"].ConnectionString;
Now if I hardcode the connection string value like public static readonly string CONNECT_STRING = "Data Source=XYZ;uid=sa;password=XXX;initial catalog=ABC;"
it works fine.I don't understand what is the issue here as web application works fine with this datalayer.
ave never used ajax.... I'm currently putting together a little web app that basically calls a program on the server itself (a command line tool) and displays the output to the web page.When the command line tool is run from the command line, it outputs status messages as it does it's thing... as it is now, my page just displays all the output when it's done. What I would like to do is show each line of output on the web page as they happen, just like when run from the command line. I'm guessing ajax is what I need... can anyone point me in the right direction for this specific scenario (user clicks button, output streams to web page as it happens without full page post backs)... a good example would be how ping.exe displays it's output on the command line
