Hi,
Crystal Report 2008 has no problem connecting to oracle 9 in Crystal Report developer.
When the same report handled by C# 2005, with same connection setting,
i.e.
Rprt.SetDatabaseLogon("user", "password");
or
Rprt.SetDatabaseLogon("user", "password", "deserver", "dbname");
other method like
ConnectionInfo
When called with
Rprt.VerifyDatabase();
It generates error "Login Failure"
Any Suggestion?
Thanks

Perhaps the Oracle client isn't seeing the database correctly. Do you have TNSNames defined correctly.
|
|
|
|
|
The same machine use for Crystal Report 2008 and VS 2005.
Therefore they are using the same TNS Setting.
When Crystal Report Developer able to connect to Oracle 9i (retrieve data and print out), it sould be able to connect to Oracle in VS 2005.

Since the error is coming from Crystal, if you're using ReportViewer, have you wired Error and HandleException events. Do they reveal any extra info?

|
|

2 ways
1.
Form1 tmp_form1 = new Form1();
tmp_form1.BackGroundImage = Image.FromFile(FILEPATH);
tmp_form1.Show();
2.Delegates And Events[^]
one more i forgot
in Form1
Form2 tmp_form2 = new Form2();
tmp_form2.Form1Reference = this;
tmp_form2.Show();
you can change form1, backgrou...
Form1Reference.BackGroundImage =.....;

If the data field in data source you are setting for crystal reports has a byte[] field, I believe crystal report will convert it to image and show it on the report. I am not sure though.

At present I am using Entity Classes for Storing Values Retrieved from DataBase .
eg : I retrieved employeeName,employeeID and Salary from Database
and assigned it to properties EntEmpname, EntEmpId,ENTSalary of entity class and using it on front end .
Works fine for one record ,
My question is If I want to retrieve Multiple Records using Entity class do I have to create that many instances of Entity class or is there any other way out ?
|
|
|
|
|
Yes, you will, by definition, need a list of the Entity class. How else could it work ?

Hi Graus,
So suppose my query returned me a 1000 records, will it be better to use a Dataset or still list of the Entity class would be better ??

If you search this you will get plenty of discussions on this topic. IMO, you should go with custom strongly typed entity classes. Fill the entity classes with DataReader. Do you know a DataSet is filled using DataReader?
Assume your entity class name is Customer, you can return 1000 records keeping in a List<Customer>. Since List(T) supports enumeration, it can be directly supplied to DataSource of all popular controls which supports data binding.

Thanx Navaneeth,

I need to develop a windows application that will take backup (check for the modified files in a particular folderand compress it ) and copy it to folder on the remote server for which this host server is mapped to . .can someone guide me ?

anupa wrote: that will take backup (check for the modified files
Use a FileSystemWatcher control to get notified when files are modified.
anupa wrote: and compress it
Use GZip compression.
|
|
|
|
|
File.Copy will copy a file. There's zip stuff built into .NET 3.5, at least. The FileAttributes class will tell you when a file was last modified.
your client can just buy something that does all of this for $30, are you charging less than that ?

Hello Sir,
I once build an application for that purpose. Email me and I'll send you the source code for it.
Best,

I did some reading about embedded resources but they all dealt with pictures and other runtime functions.
How do I copy the file from a resource?
Thanks.
